Background: There has been a recent interest in the double row repair method for arthroscopic rotator cuff repair following favourable biomechanical results reported by some studies. The purpose of this study was to compare the clinical results of arthroscopic single row and double row repair methods in the full-thickness rotator cuff tears. Materials and Methods: 22 patients of arthroscopic single row repair (group I) and 25 patients who underwent double row repair (group II) from March 2003 to March 2005 were retrospectively evaluated and compared for the clinical outcomes. The mean age was 58 years and 56 years respectively for group I and II. The average follow-up in the two groups was 24 months. The evaluation was done by using the University of California Los Angeles (UCLA) rating scale and the shoulder index of the American Shoulder and Elbow Surgeons (ASES). Results: In Group I, the mean ASES score increased from 30.48 to 87.40 and the mean ASES score increased from 32.00 to 91.45 in the Group II. The mean UCLA score increased from the preoperative 12.23 to 30.82 in Group I and from 12.20 to 32.40 in Group II. Each method has shown no statistical clinical differences between two methods, but based on the sub scores of UCLA score, the double row repair method yields better results for the strength, and it gives more satisfaction to the patients than the single row repair method. Conclusions: Comparing the two methods, double row repair group showed better clinical results in recovering strength and gave more satisfaction to the patients but no statistical clinical difference was found between 2 methods.

The purpose of this study is to report on our experience with thermal capsulorrhaphy in the treatment of multidirectional instability of the shoulder. Thirty-three consecutive patients (33 shoulders) with multidirectional instability were treated with arthroscopic thermal capsulorrhaphy. Twelve patients had a history of traumatic dislocation. Three patients had been previously treated with open inferior capsular shift procedures. At a mean follow-up of 36 months (range, 24-40 months), results were available for 30 patients. On the basis of the UCLA rating scale, out of a possible 35 points, the mean preoperative score was 16.7 points and postoperatively it was 30.1 points, with 3 excellent, 20 good, and 7 poor results. Twenty-three patients (76%) were returned to full activity. In our experience the majority of patients with multidirectional instability were able to return to their previous occupations in the armed forces following thermal capsulorrhaphy. More information further defining the biomechanical pathology of capsular laxity and the specific role of electrothermal shrinkage in treating shoulder instability is needed.

The treatment of rotator cuff injury in the absence of a full-thickness tear has traditionally consisted of acromioplasty. However, this disorder may also be treated by arthroscopic rotator cuff debridement without acromioplasty. Our previous study of 79 shoulders so treated reported 87% good or excellent results at an average 53-month follow-up. The purpose of this article is to report the long-term, average 9.5-year follow-up of this cohort. Long-term follow-up of case series. We retrospectively reviewed the records of 62 shoulders in 60 patients who had undergone arthroscopic rotator cuff debridement for partial-thickness rotator cuff tears. Demographic criteria, residual pain, and the ability to return to recreational athletics were noted. The UCLA Shoulder Score and the Simple Shoulder Test scores were determined and statistical analysis performed. Using the UCLA Shoulder Score, there were 79% excellent or good results at an average 114 months of follow-up. Patients with Workers' Compensation claims had significantly worse results, with only 40% rated good or excellent. Of the 60 patients, 77% had no or only minimal pain, 57% were still able to perform recreational athletics without difficulty, and 20% could participate at a lower level of intensity. Arthroscopic debridement of rotator cuff injury in the absence of a full-thickness tear has good long-term results and minimizes additional surgical trauma. Level IV, case series.

The treatment of symptomatic partial rotator cuff tear has presented substantial challenge to orthopaedic surgeons as it can vary from conservative to surgical repair. Researches have established the influence of platelet rich plasma in healing damaged tissue. Currently very few data are available regarding the evidence of clinical and radiological outcome of partial rotator cuff tear treated with ultrasound guided platelet rich plasma injection in English literature. 20 patients with symptomatic partial rotator cuff tears were treated with ultrasound guided platelet rich plasma injection. Before and after the injection of platelet rich plasma scoring was done with visual analogue score, Constant shoulder score, and UCLA shoulder score at 8 weeks and third month. A review ultrasound was performed 8 weeks after platelet rich plasma injection to assess the rotator cuff status. Our study showed statistically significant improvements in 17 patients in VAS pain score, constant shoulder score and UCLA shoulder score. No significant changes in ROM were noted when matched to the contra-lateral side ( P < 0.001) at the 3 month follow-up. The study also showed good healing on radiological evaluation with ultrasonogram 8 weeks after platelet rich plasma injection. Ultrasound guided platelet rich plasma injection for partial rotator cuff tears is an effective procedure that leads to significant decrease in pain, improvement in shoulder functions, much cost-effective and less problematic compared to a surgical treatment.

To study effect of shoulder joint function after rotator cuff repair of polylactic acid absorbable membrane. From September 2015 to December 2016, 50 patients diagnosed with rotator cuff tear were selected and divided into treatment group and control group. There were 25 patients in control group, including 12 males and 13 females, with an average age of (48.7±3.5) years old, who received simple arthroscopic rotator cuff repair. There were 25 patients in treatment group, including 11 males and 14 females, with an average age of(49.2±4.1) years old, who performed arthroscopic rotator cuff repair with implanting polylactic acid absorbable membraneon shoulder of rotator cuff. Preoperative and postoperative VAS score, ASES score and UCLA score were recorded and compared between two groups. At 6 months after operation, preoperative VAS score in control group was 5.48±1.12, and decreased as 1.28±0.84 after operation; ASES score before operation was 52.24±4.64, and improved to 86.92±3.20 after operation;preoperative UCLA score improved from 14.36±1.89 before operation to 30.72±1.28 after operation. In treatment group, VAS score decreased from 5.36±1.32 before operation to 1.40±0.71 after operation;preoperative ASES score was 51.04±4.09, and improved to 88.96±2.79 after operation; UCLA score improved from 15.12±1.81 before operation to 32.12±1.33 after operation. There was no significant difference in VAS score between two groups, and ASES score, UCLA score in treatment group was obviously better than control group. Application of polylactic acid absorbable medical membrane could obviously improve shoulder function, and effectively prevent acromion adhesion after arthroscopic rotator cuff repair.

Reverse shoulder arthroplasty (RSA) can restore active elevation in rotator-cuff-deficient shoulders. However, RSA cannot restore active external rotation. The combination of latissimus dorsi transfer with RSA has been reported to restore both active elevation and external rotation. We hypothesised that in the combined procedure, harvesting the latissimus dorsi with a small piece of bone, leads to good tendon integrity, low rupture rates and good clinical outcome. Between 2004 and 2010, 13 patients (13 shoulders) were treated with RSA in combination with latissimus dorsi transfer in a modified manner. The mean follow-up was 65.4 months, and the mean age at index surgery was 71.1 years. All patients had external rotation lag sign and positive hornblower's sign, as well as radiological signs of cuff-tear arthropathy (Hamada 3, 4 or 5) and fatty infiltration grade 3 according to Goutallier et al. on magnetic resonance imaging (MRI). The outcome measures included the Constant Murley Score, University of California-Los Angeles (UCLA) shoulder score, Simple Shoulder Test (SST), visual analogue scale (VAS) and the Activities of Daily Living Requiring External Rotation (ADLER) score. Tendon integrity was evaluated with dynamic ultrasound. All patients were asked at final follow-up to rate their satisfaction as excellent, good, satisfied or dissatisfied. The overall mean Constant-Murley Shoulder Outcome Score (CMS) improved from 20.4 to 64.3 points (p < 0.001). Mean VAS pain score decreased from 6.8 to 1.1 (p < 0.001)., mean UCLA score improved from 7.9 to 26.4 (p < 0.001), mean SST score improved from 2.3 to 7.9 (p < 0.001) and mean postoperative ADLER score was 26 points. The average degree of abduction improved from 45° to 129° (p < 0.001), the average degree of anterior flexion improved from 55° to 138° (p < 0.001) and the average degree of external rotation improved from -16° to 21° (p < 0.001). Eight patients rated their results as very satisfied, three as satisfied and two as dissatisfied. This modified technique, which avoids cutting the pectoralis major tendon and involves harvesting the tendon together with a small piece of bone, leads to good or even better functional results compared with the results reported in the literature, and also has high patient satisfaction and low failure rates.

To evaluate the clinical and radiographic results from arthroscopic surgical treatment of the rotator cuff in patients with calcifying tendinitis. A retrospective study was conducted on twenty patients who underwent arthroscopic treatment for calcifying tendinitis of the shoulder between March 1999 and November 2005. Six patients were excluded due to loss of follow-up. The average follow-up period was 41.4 months. Eight patients (57%) were female and six (43%) were male. The right side was affected in 10 cases (71%) and the left in four cases (29%). Nine cases (64%) had calcification in the supraspinatus tendon, two (14%) in the infraspinatus tendon, and three (21%) in both tendons. In all cases, resection of the calcium deposits was performed by means of a needle (Jelco® No. 14) in combination with curettage (mini-curette). Two shoulders (14%) underwent subacromial decompression, and one (7%) underwent excision of the distal clavicle. A tendon-tendon suture was performed in three shoulders (21%). None of the patients underwent tendon-bone reinsertion. The mean score obtained on the UCLA scale was 33 points (26-35), thus indicating that a majority of patients had good results. In the final radiographic evaluation, none of the patients showed signs of calcification. Arthroscopic treatment of calcifying tendinitis of the shoulder safely allows excision of the calcification, leading to good results in relation to shoulder pain and function.

The purpose of this study was to investigate coactivation (CoA) testing as a clinical tool to monitor motor learning after latissimus dorsi tendon transfer. We evaluated 20 patients clinically with the American Shoulder and Elbow Surgeons (ASES) and University of California-Los Angeles (UCLA) outcomes scores, visual analog scale, active external rotation (aER), and isometric strength testing in abduction and external rotation. Measurements of aER were performed while the latissimus dorsi was activated in its new function of external rotation with concomitant activation (coactivation) of its native functions (adduction and extension). Bilateral surface electromyographic (EMG) activity was recorded during aER measurements and the strength testing procedure (EMG activity ratio: with/without CoA). Patients were divided into two groups (excellent/good vs fair/poor) according to the results of the ASES and UCLA scores. The mean follow-up was 57.8 ± 25.2 months. Subdivided by clinical scores, the superior outcome group lost aER with CoA, whereas the inferior outcome group gained aER (UCLA score: -2.2° ± 7.4° vs +4.3° ± 4.1°; P = .031). Patients with inferior outcomes in the ASES score showed higher latissimus dorsi EMG activity ratios (P = .027), suggesting an inadequate motor learning process. Isometric strength testing revealed that the latissimus dorsi transfer had significantly greater activity compared with the contralateral side (external rotation, P = .008; abduction, P = .006) but did not have comparable strength (external rotation, P = .017; abduction, P = .009). Patients with inferior clinical results were more likely to be dependent on CoA to gain external rotation. Therefore, CoA testing may be used as a tool to evaluate the status of postoperative motor learning after latissimus dorsi transfer.

To evaluate shoulder functional results and the retear rate of arthroscopic repair of the rotator cuff augmented with platelet-rich plasma (PRP). Prospective case series with single-row arthroscopic repair of the rotator cuff augmented with PRP. Only cases of isolated supraspinatus tears with retraction of less than 3 cm were included in this series. The PRP used was obtained by apheresis. It was applied on liquid consistency in its activated form, with the addition of autologous thrombin. Patients were evaluated after 12 months of the surgical procedure. The Constant-Murley, UCLA and VAS scales were used, and the retear rate was assessed using magnetic resonance imaging (MRI). Fourteen patients were evaluated (14 shoulders). The mean Constant-Murley score was 45.64 ± 12.29 before the operation and evolved to 80.78 ± 13.22 after the operation (p < 0.001). The UCLA score increased from 13.78 ± 5.66 to 31.43 ± 3.9 (p < 0.001). The patients' pain level decreased from a median of 7.5 (p25% = 6, p75% = 8) to 0.5 (p25% = 0, p75% = 3) (p = 0.0013) according to the VAS score. None of the patients presented complete retear. Three patients (21.4%) showed partial retear, without transfixation. Only one patient developed complications (adhesive capsulitis). Patients submitted to arthroscopic rotator cuff repair augmented with PRP showed significant functional improvement and none of them had complete retearing.

To report on the knowledge and use of both general and disease-specific shoulder outcomes scores among orthopedic surgeons. A 22-question Internet survey was administered to members of the American Orthopaedic Society for Sports Medicine, the Arthroscopy Association of North American, and the International Society of Arthroscopy, Knee Surgery, and Orthopedic Sports Medicine via voluntary e-mail participation. Questions targeted demographic information, preferred surgical management of shoulder conditions, and the preferred use of shoulder outcomes instruments in clinical practice. Excluding defunct and duplicate e-mails among membership societies, a total of 3892 unique e-mails were sent, from which 1129 surveys were returned and were fully completed (29%). The largest number of respondents were in private practice (52%); 21% were in academia; and 26% were in a mix of settings. As for location, 74% practiced in the United States, 10% in Europe, 8% in Mexico/South America, and 6% in Asia. A total of 31% total respondents used scores all or most of the time, and 30% used scores at least some of the time. Respondents felt that the 3 most commonly utilized shoulder scores were the American Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) score, and the Constant score. The majority of respondents (76%) performed all-arthroscopic instability repairs. The ASES and Western Ontario Shoulder Instability Index (WOSI) scores were the most preferred measures to monitor instability patients, whether or not the scores were actually implemented in their practice. Most perform between 10 and 25 superior labrum anterior-posterior repairs per year and preferred the ASES, UCLA, and Constant scores for these repairs; rotator cuff repair preferred outcomes instruments were similar. When asked to choose 1 score for all shoulder conditions, the ASES was the clear favorite. This study reports the knowledge and utilization of shoulder scores for both general and disease-specific conditions. Most respondents preferred the ASES score for most shoulder conditions; however, other scores, such as the WOSI, the Constant, and the Short-Form (SF)-36/12, were popular. This information offers insight into the current and future use of shoulder outcomes both for general and disease-specific use.

To explore the effectiveness of the arthroscopic separate double-layer suture bridge technique in treatment of the delaminated rotator cuff tear. Between May 2013 and May 2015, 54 patients with the delaminated rotator cuff tears were recruited in the study. They were randomly allocated into 2 groups to receive repair either using arthroscopic separate double-layer suture bridge technique (trial group, n =28) or using arthroscopic whole-layer suture bridge technique (control group, n =26). There was no significant difference in gender, age, injured side, tear type, and preoperative visual analogue scale (VAS) score, Constants score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score, and the range of motion of shoulder joint between 2 groups ( P >0.05). Postoperative functional scores, range of motion, and recurrence rate of tear in 2 groups were observed and compared. The operation time was significant longer in trial group than in control group ( t =8.383, P =0.000). All incisions healed at stage Ⅰ without postoperative complication. All the patients were followed up 12 months. At 12 months postoperatively, the UCLA score, ASES score, VAS score, Constant score, and the range of motion were significantly improved when compared with the preoperative values in 2 groups ( P <0.05). However there was no significant difference in above indexes between 2 groups ( P >0.05). Four cases (14.3%) of rotator cuff tear recurred in trial group while 5 cases (19.2%) in control group, showing no significant difference ( χ 2 =0.237, P =0.626). Compared with the arthroscopic whole-layer suture bridge technique, arthroscopic separate double-layer suture bridge technique presents no significant difference in the shoulder function score, the range of motion, and recurrence of rotator cuff tear, while having a longer operation time.

We identified ten patients who underwent arthroscopic revision of anterior shoulder stabilisation between 1999 and 2005. Their results were compared with 15 patients, matched for age and gender, who had a primary arthroscopic stabilisation during the same period. At a mean follow-up of 37 and 36 months, respectively, the scores for pain and shoulder function improved significantly between the pre-operative and follow-up visits in both groups (p = 0.002), with no significant difference between them (p = 0.4). The UCLA and Rowe shoulder scores improved significantly (p = 0.004 and p = 0.002, respectively), with no statistically significant differences between groups (p = 0.6). Kaplan-Meier analysis for time to recurrent instability showed no differences between the groups (p = 0.2). These results suggest that arthroscopic revision anterior shoulder stabilisation is as reliable as primary arthroscopic stabilisation for patients who have had previous open surgery for recurrent anterior instability.

The aim of this study was to compare the short-term outcomes of arthroscopic TightRope ® fixation with that of hook plate fixation in patients with acute unstable acromioclavicular joint dislocations. We conducted a prospective case-control study of twenty-six patients with an acute ACJ dislocation who underwent surgical repair with either an arthroscopic TightRope ® fixation or a hook plate from 2013 to 2016. Clinical and radiological data were collected prospectively. Clinical outcomes were evaluated using the Constant Score, the University of California at Los Angeles (UCLA) Shoulder Score, Oxford Shoulder Score as well as the visual analogue scale. Radiological outcomes were assessed with the coracoclavicular distance (CCD). Sixteen patients underwent arthroscopic TightRope ® fixation, while 10 patients underwent hook plate fixation. There were no significant differences in the preoperative variables except for the mean UCLA 4b infraspinatus score (TightRope ® 2.8 vs. hook plate 3.8; p = 0.030). Duration of surgery was significantly longer in the TightRope ® group. At 1 year post-operatively, the TightRope ® group had a significantly better Constant Score and CCD with no complications. All patients with hook plate fixation had to undergo a second procedure for removal of implant, and 3 patients had complications. Arthroscopic TightRope ® fixation is a good option for the treatment of acute unstable ACJ dislocations. It has better short-term clinical and radiological outcomes as well as lesser complications when compared to hook plate fixation. Therapeutic, Level III.

Calcified rotator cuff tendinitis is a common cause of chronic shoulder pain that leads to significant pain and functional limitations. Although most patients respond well to conservative treatment, some eventually require surgical treatment. To evaluate the clinical outcome with arthroscopic removal of calcific deposit and rotator cuff repair without acromioplasty for the treatment of calcific tendinitis of the supraspinatus tendon. Case series; Level of evidence, 4. This study retrospectively evaluated 30 consecutive patients with a mean age of 49.2 years. The mean follow-up was 35 months (range, 24-88 months). Pre- and postoperative functional assessment was performed using the Constant score, University of California Los Angeles (UCLA) score, and Quick Disabilities of the Arm, Shoulder, and Hand (DASH). Pain was assessed by visual analog scale (VAS). Radiographs and magnetic resonance imaging (MRI) were performed to evaluate the recurrence of calcifications and the indemnity of the supraspinatus tendon repair. Significant improvement was obtained for pain (mean VAS, 8.7 before surgery to 0.8 after; P < .001). The mean Constant score increased from 23.9 preoperatively to 85.3 postoperatively (P < .001), the mean Quick DASH score decreased from 47.3 preoperatively to 8.97 postoperatively (P < .001), and the UCLA score increased from 15.8 preoperatively to 32.2 postoperatively (P < .001). MRI examination at last follow-up (70% of patients) showed no tendon tears, and 96.2% of patients were satisfied with their results. Arthroscopic removal and rotator cuff repair without acromioplasty can lead to good results in patients with symptomatic calcifying tendonitis of the supraspinatus tendon.

The UCLA LS-R is the most extensively used scale to assess loneliness. However, few studies examine the scale's use on older individuals. The goal of the study is to analyse the suitability of the scale´s structure for assessing older individuals. The UCLA LS-R scale was administered to a random sample of 409 community-dwelling residents of Madrid (53% women) aged 65-84 years (obtained from the MentDis_ICF65+ study). Confirmatory factor analysis was used to assess the factor structure of the UCLA LS-R. The internal consistency of the scale obtained a Cronbach's alpha of .85. All the analysed models of factor structure of the UCLA LS-R achieved a fairly good fit and RMSEA values over .80. The models that best fit the empirical data are those of Hojat (1982) and Borges et al. (2008). The data suggest an equivalent effectiveness of UCLA LS-R in adults under 65 and over 65, which may indicate a similar structure of the loneliness construct in both populations. This outcome is consistent with the idea that loneliness has two dimensions: emotional loneliness and social loneliness. The use of short measures that are easy to apply and interpret should help primary care professionals identify loneliness problems in older individuals sooner and more accurately.

The authors report the results of a retrospective study of 59 arthroscopic acromioplasties. Objective shoulder assessment was made following the relative Constant score and UCLA rating scale. Subjective satisfaction of the patient was assessed on an analogic scale. The patients were divided into 3 groups, according to the subacromial pathology treated. The first group (27 shoulders in 23 patients) included patients with subacromial impingement without a complete rotator cuff tear. The objective result, between 80 and 90%, was close to results in others series reported. Distinction between patients with no tear or partial tear of the cuff showed better results for patients with partial tears. This surprising finding may be at least partially explained by the fact that these patients were older than those without a cuff tear. The results of this study, and the review of the literature, confirmed the value of subacromial decompression as a treatment for impingement without complete cuff tear resistant to at least 6 months of conservative treatment; comparison between surgical and arthroscopic series showed similar results. The second group (19 shoulders in 19 patients) included patients with impingement and complete cuff tear. The objective results and the literature review led us to specify indications. Subacromial decompression with debridment of the tear has given excellent results in older patients--over 60 for most authors--when the tear was limited. In our study, the function of the shoulder at revision was good when the tear was limited to the supraspinatus and part of the infraspinatus. The third group (13 shoulders in 10 patients) included patients with calcifying tendinitis. Arthroscopic acromioplasty was performed in every case; excision of the calcification was performed in less than half of the cases and did not influence the final result. The calcifications had disappeared at revision in all cases. This may suggest that the treatment of the associated impingement was the most important procedure in these cases.

The purpose of this study was to evaluate the clinical and radiologic outcomes of unstable distal clavicle fractures treated with anatomic plate fixation without coracoclavicular ligament augmentation and to compare the outcome of Neer type IIA with that of type IIB. Twenty-five patients with unstable distal clavicle fractures who underwent anatomic plate fixation without coracoclavicular ligament augmentation were enrolled prospectively, including 9 patients of Neer type IIA and 16 patients of Neer type IIB. Clinical outcomes were evaluated using Constant and University of California-Los Angeles (UCLA) scores. Coracoclavicular distance was measured on plain radiographs. Bone union was achieved in all patients. Satisfactory clinical and radiologic outcomes were obtained regardless of fracture type. After operation, the mean coracoclavicular distance on the injured side was increased by 10% compared with the uninjured side. However, between the patients who showed an increased coracoclavicular distance >10% (Constant score, 89.4 ± 3.7; UCLA score, 32.6 ± 3) and the patients with increased coracoclavicular distance <10% of the uninjured side (Constant score, 88.7 ± 3.6; UCLA score, 31.9 ± 3), there was no statistically significant difference in clinical outcomes of Constant score (P = .934) and UCLA score (P = .598). In unstable distal clavicle fractures, precontoured anatomic plate fixation without coracoclavicular ligament augmentation showed satisfactory clinical outcomes and high union rates even with a small lateral fragment. Patients who had increased coracoclavicular distance also demonstrated satisfactory shoulder functional outcomes regardless of the fracture type. Therefore, anatomic plate fixation without additional coracoclavicular ligament augmentation can be considered one of the treatment options for unstable distal clavicle fracture.

The use of platelet-rich plasma (PRP) is an innovative clinical therapy, especially in arthroscopic rotator cuff repair. The purpose of this study was to compare the clinical improvement and tendon-to-bone healing with and without PRP therapy in arthroscopic rotator cuff repair. A systematic search was done in the major medical databases to evaluate the studies using PRP therapy (PRP+) or with no PRP (PRP-) for the treatment of patients with rotator cuff tears. We reviewed clinical scores such as the Constant score, the American Shoulder and Elbow Surgeons score, the University of California at Los Angeles (UCLA) Shoulder Rating Scale, the Simple Shoulder Test, and the failure-to-heal rate by magnetic resonance imaging between PRP+ and PRP- groups. Five studies included in this review were used for a meta-analysis based on data availability. There were no statistically significant differences between PRP+ and PRP- groups for overall outcome scores (P > .05). However, the PRP+ group exhibited better healing rates postoperatively than the PRP- group (P = .03) in small/moderate full-thickness tears. The use of PRP therapy in full-thickness rotator cuff repairs showed no statistically significant difference compared with no PRP therapy in clinical outcome scores, but the failure-to-heal rate was significantly decreased when PRP was used for treatment of small-to-moderately sized tears. PRP therapy may improve tendon-to-bone healing in patients with small or moderate rotator cuff tears. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

The Japanese Orthopaedic Association shoulder score cutoff values were calculated in patients with rotator cuff repair using the University of California at Los Angeles shoulder score. Overall, 175 patients with rotator cuff repair were subjects in this study. The University of California at Los Angeles and Japanese Orthopaedic Association shoulder scores were evaluated before surgery and at 3, 6, 9, and 12 months after surgery. The cutoff value of the Japanese Orthopaedic Association shoulder score was determined using the 4-stage criteria of the University of California at Los Angeles shoulder score and a University of California at Los Angeles shoulder score of 28 points, which is the boundary between an excellent/good group and a fair/poor group. Both the JOA shoulder and UCLA shoulder scores showed significant improvement at 6, 9, and 12 months from the preoperative scores (p < 0.0001). There was a strong correlation between the total values of the two scores (r = 0.85, p < 0.0001). The cutoff value of the Japanese Orthopaedic Association shoulder score based on the highest accuracy from receiver operating characteristic curve analysis was 83 points. A Japanese Orthopaedic Association shoulder score cutoff value of 83 was equivalent to a University of California at Los Angeles shoulder score cutoff value of 28 for distinguishing between excellent/good and fair/poor outcomes after rotator cuff repair.

2016-05-04

Fracture of the clavicle is common, accounting for 2.6 to 4.0 % of all fractures, with an overall incidence of 36.5 to 64 per 100,000 per year. Around 80 % of clavicle fractures occur in the middle third of the clavicle. Randomised controlled trials comparing treatment interventions have failed to indicate the best therapeutic practices for these fractures. The objective of this study is to evaluate the effects (benefits and harms) of two commonly-used conservative interventions: the figure-of-eight bandage versus the arm sling as treatments of middle-third clavicle fractures. This project has been designed as a single-centre, two-arm randomised controlled trial that will compare two interventions: figure-of-eight bandage versus the arm sling. We propose to recruit 110 adults, aged 18 years or older, with an acute (less than 10 days since injury) middle-third clavicle fracture. The primary outcomes to be evaluated will be function and/or disability measured by the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire. In order to assess the secondary outcomes, the Modified University of California at Los Angeles (modified - UCLA) Shoulder Rating Scale will be used. The occurrence of pain (Visual Analogue Scale for pain (VAS)), treatment failure, adverse events and the ability to return to previous activities will also be recorded and evaluated as secondary outcomes. the primary outcome DASH score and the secondary outcomes - modified UCLA and VAS scores - will be analysed graphically. We will apply generalised mixed models with the intervention groups (two levels), and time-point assessments (seven levels) as fixed effects and patients as a random effect. According to the current literature there is very limited evidence from two small trials regarding the effectiveness of different methods of conservative interventions for treating clavicle fractures. This is the first randomised controlled trial comparing the figure-of-eight bandage versus the arm sling for treating clavicle fractures that follows the CONSORT Statement guidelines.

In cases of the large or massive rotator cuff tears, retear rates after rotator cuff repairs remain high. We introduced an arthroscopic-assisted modified Debeyre-Patte procedure which enables to decrease the tension of torn rotator cuff by sliding supraspinatus and infraspinatus laterally keeping fascia connection to the rhomboids. The objective of this study was to examine the clinical outcomes and retear rates after an arthroscopic-assisted modified Debeyre-Patte procedure for irreparable large and massive rotator cuff tears. Thirty-three rotator cuff tear patients (34 shoulders) were selected. These patients underwent arthroscopic-assisted modified Debeyre-Patte procedures and were observed postoperatively for at least 24 months. Magnetic resonance imaging (MRI) was used to evaluate the preoperative location of the torn rotator cuff stump and fatty infiltration of the muscles composing the rotator cuff, as well as the repaired rotator cuffs. Shoulder functional evaluations through the use of the Constant and Murley scores and the University of California Los Angeles (UCLA) shoulder score were compared before and after surgery, and the preoperative global fatty degeneration index (GFDI) was compared between retear and healed shoulders. MRI showed that 77% of shoulders were healed and 23% exhibited retear postoperatively. The mean preoperative GFDI was 1.99 among the 26 healed shoulders and 2.54 among the 8 retear shoulders (p < .05). When the Goutallier's classification was grade 3 or lower for all 3 cuff muscles for fatty infiltration, the retear rate was 14.3%. The mean Constant and Murley scores in healed and retear groups respectively improved from 34.7 ± 15.8, 30.0 ± 15.1 points (p = 0.47) preoperatively to 70.8 ± 8.3, 53.9 ± 14.0 points (p < .001), and UCLA scores in healed and retear groups from 13.8 ± 3.9, 12.4 ± 5.0 points (p = 0.46) preoperatively to 32.8 ± 2.7, 28.4 ± 3.6 points (p < .001). The clinical outcomes of healed shoulders after the arthroscopic-assisted modified Debeyre-Patte procedure were favorable. If the torn rotator cuff stump is retracted near the glenoid fossa, and the rotator cuff muscle scored Goutallier grade 3 or lower, this modified Debeyre-Patte procedure would be a viable option.

Rotator cuff repair typically results in a satisfactory, although variable, clinical outcome. However, anatomic failure of the repaired tendon often occurs. Patch augmentation can improve the results of open rotator cuff repair by supporting the healing process, protecting the suture, and reducing friction in the subacromial space. Cohort study; Level of evidence, 3. A total of 152 patients with a posterosuperior massive rotator cuff tear were treated by open repair only (control group; n = 51; mean age, 67.06 ± 4.42 years), open repair together with collagen patch augmentation (collagen group; n = 49; mean age, 66.53 ± 5.17 years), or open repair together with polypropylene patch augmentation (polypropylene group; n = 52; mean age, 66.17 ± 5.44 years) and were retrospectively studied. Patients were evaluated preoperatively and after 36 months with a visual analog scale (VAS) and the University of California, Los Angeles (UCLA) shoulder rating scale and by measuring elevation of the scapular plane and strength with a dynamometer. The VAS and UCLA scores were also obtained 2 months postoperatively. Tendon integrity was assessed after 1 year by ultrasound. Patients were homogeneous as per the preoperative assessment. After 2 months, results (mean ± standard deviation) for the control, collagen, and polypropylene groups, respectively, were as follows: VAS scores were 6.96 ± 1.11, 6.46 ± 1.02, and 4.92 ± 0.90, while UCLA scores were 11.29 ± 1.46, 11.40 ± 1.51, and 19.15 ± 1.99. After 36 months, the mean scores for the respective groups were 3.66 ± 1.05, 4.06 ± 1.02, and 3.28 ± 1.10 for the VAS and 14.88 ± 1.98, 14.69 ± 1.99, and 24.61 ± 3.22 for the UCLA scale. In addition, after 36 months, elevation on the scapular plane was 140.68° ± 9.84°, 140.61° ± 12.48°, and 174.71° ± 8.18°, and abduction strength was 8.73 ± 0.54 kg, 9.03 ± 0.60 kg, and 13.79 ± 0.64 kg for the control, collagen, and polypropylene groups, respectively. The retear rate after 12 months was 41% (21/51) for the control group, 51% (25/49) for the collagen group, and 17% (9/52) for the polypropylene group. In particular, the reduced 12-month retear rate and the increased UCLA scores, abduction strength, and elevation at 3-year follow-up were statistically significant for patients treated with a polypropylene patch compared with those treated with repair only or with a collagen patch. Polypropylene patch augmentation of rotator cuff repair was demonstrated to significantly improve the 36-month outcome in terms of function, strength, and retear rate.

To evaluate the results from surgical treatment of 84 cases of acute acromioclavicular dislocation, using a posterosuperior access route. Eighty-four cases of acute acromioclavicular dislocation (grade III in the Allman-Tossy classification) operated between November 2002 and May 2010 were evaluated. The patients' mean age was 34 years. The diagnoses were made using clinical and radiographic evaluations. The patients were operated by the same surgical team, within three weeks of the date of the trauma, using a posterosuperior approach to the shoulder to access the top of the base of the coracoid process for placement of two anchors, which were used in reducing the dislocation. The minimum follow-up was 12 months. The postoperative clinical-radiographic evaluation was done using the modified Karlsson criteria and the University of California at Los Angeles (UCLA) score. 92.8% of the 84 patients treated presented good or excellent results, and 7.2% presented fair or poor results, using the UCLA assessment score. According to the modified Karlsson criteria, 76.2% were assessed as grade A, 17.9% as grade B and 5.9% as grade C. The posterosuperior access route to the shoulder is a new option for accessing the coracoid process and treating acromioclavicular dislocation, with clinical and radiographic results equivalent to those in the literature.

The treatment of 3and 4 part proximal humeral fractures in elderly patients is still controversial. The frequent co-existence of poor quality bone and rotator cuff abnormalities in patients with multiple clinical conditions and with difficulties for physical rehabilitation leads to disappointing clinical results, even when the radiological images are acceptable. To evaluate the clinical, radiological, and functional results in patients over 65 years old with complex proximal humerus fractures treated with reverse shoulder arthroplasty. A prospective review was carried out on 30 patients (26 women and 4 men) with proximal humeral fractures treated with reverse shoulder arthroplasty in our department. The mean age was 74.9 years (SD=6.3), and the mean follow-up was 34.5 months (SD=19.3). Clinical and functional results were acceptable, with a mean forward flexion of 124° and a mean external rotation of 13°. The mean abbreviated Constant abbreviated score was 49.1 (SD=14.1), 27 (SD=6.3) in the UCLA scale, and 32.2 (SD=19.2) in the QuickDASH questionnaire. The large majority (80%) of the patients are pain free, and they do not need medication to do daily activities. The complication rate was 13.3%. We consider that reverse shoulder arthroplasty is a valid option to treat 3and 4 part proximal humeral fractures in elderly patients. The surgical goals should include the anatomical reconstruction of the tuberosities, avoiding enlargement of the operated arm greater than 2cm. Copyright © 2016 SECOT.

Rotator cuff tears have a high recurrence rate, even after arthroscopic rotator cuff repair. Although some biomechanical evidence suggests the superiority of the double-row vs the single-row technique, clinical findings regarding these methods have been controversial. The purpose of this study was to determine whether the double-row repair method results in a lower incidence of recurrent tearing compared with the single-row method. Electronic databases were systematically searched to identify reports of randomized, controlled trials (RCTs) comparing single-row with double-row rotator cuff repair. The primary outcome assessed was retear of the repaired cuff. Secondary outcome measures were the American Shoulder and Elbow Surgeons (ASES) shoulder score, the Constant shoulder score, and the University of California, Los Angeles (UCLA) score. Heterogeneity between the included studies was assessed. Six studies involving 428 patients were included in the review. Compared with single-row repair, double-row repair demonstrated a lower retear incidence (risk ratio [RR]=1.71 [95% confidence interval (CI), 1.18-2.49]; P=.005; I(2)=0%) and a reduced incidence of partial-thickness retears (RR=2.16 [95% CI, 1.26-3.71]; P=.005; I(2)=26%). Functional ASES, Constant, and UCLA scores showed no difference between single- and double-row cuff repairs. Use of the double-row technique decreased the incidence of retears, especially partial-thickness retears, compared with the single-row technique. The functional outcome was not significantly different between the 2 techniques. To improve the structural outcome of the repaired rotator cuff, surgeons should use the double-row technique. However, further long-term RCTs on this topic are needed. Copyright 2014, SLACK Incorporated.

This prospective, randomized study was performed to evaluate the results of mini-open and arthroscopic rotator cuff repair in a comparative case series of patients followed for 24 months. A total of 125 patients were randomized to mini-open (Group I) or arthroscopic (Group II) rotator cuff repair at the time of surgical intervention. The University of California Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeons (ASES) index, and muscle strength were measured to evaluate the clinical results, while magnetic resonance arthrography was used at 24-month follow-up to investigate the postoperative rotator cuff integrity. Fifty-three patients in Group I and 55 patients in Group II were available for evaluation at 24-month follow-up. At 24-month follow-up, the UCLA score, the ASES index, and muscle strength were statistically significantly increased in both groups postoperatively, while no significant difference was detected between the 2 groups. Intact rotator cuffs were investigated in 42 patients in Group I and 35 in Group II, and there was a significant difference in postoperative structural integrity between the two groups (P < 0.05). When analysis was limited to the patients with full-thickness tear, the muscle strength of the shoulder was significantly better in Group II, and the retearing rate was significantly higher in Group II. Based on the results obtained from this study, it can be indicated that arthroscopic and mini-open rotator cuff repair displayed substantially equal outcomes, except for higher retearing rate in the arthroscopic repair group. While for patients with full-thickness tear, arthroscopic rotator cuff repair displayed better shoulder strength and significantly higher retearing rate as compared to mini-open rotator cuff repair at 24-month follow-up.

To evaluate the methods and the outcomes of complex intra-articular glenoid fractures, treated by open reduction and internal fixations. The outcomes of 11 cases of complex intra-articular glenoid scapular fractures were retrospectively analyzed. The fractures were classified as type IV in five cases, type Va in two and Vb in four cases, according to Ideberg classification system. The mean step or gap between the main articular fragments was 6.3 ± 6.2 (4-25) mm. The fractures were openly reduced through a Judet approach and fixed with reconstructive plates or bands placed on the lateral and medial side of affected scapula, respectively. The main articular fragments were strengthened with a 4.0-mm cannulated screw in five cases. The bone union, the anterior flexion, the external and internal rotation of the shoulders were checked and recorded. The functional outcomes were evaluated using DASH questionnaire, Constant and UCLA shoulder score systems, respectively. 11 patients were followed up with an average of 28.2 ± 12.6 (12-50) months. All the fractures were united smoothly without second intervention. At the latest visiting, the mean anterior flexion of affected shoulder was 157.3 ± 7.37° (range 150°-170°), the mean external rotation of the affected shoulder was 58.2 ± 7.5° (range 50°-70°). When the shoulder in the internal rotation, the extended thumb reached to L4 or L1 or T10 or T7 in one case, to T12 in two cases and to T8 in four cases, respectively, the mean Constant score was 91.7 ± 2.8 (86-96) points. The mean UCLA score was 32.7 ± 1.7 (30-35) points, leading to four cases of excellent and seven cases of good results. The mean DASH score was 7.4 ± 3.3 (3.4-13) points. Good outcomes could be obtained when Ideberg IV and V glenoid fractures were treated by open reduction and internal fixation through a Judet approach.

The optimal procedure for anterior shoulder instability with a borderline (15%-20%) bone defect on the anterior rim of the glenoid is still controversial. To compare the clinical outcome and recurrence rate between the arthroscopic Bankart repair and Latarjet procedure among patients with recurrent anterior shoulder instability and a borderline glenoid bone defect. Cohort study; Level of evidence, 3. The authors retrospectively reviewed cases of arthroscopic Bankart repair and the Latarjet procedure for recurrent anterior shoulder instability with a borderline (15%-20%) glenoid bone defect. Enrollment comprised 149 patients (Bankart group, n = 118; Latarjet group, n = 31). The mean follow-up and age at operation were 28.9 ± 7.3 months (range, 24-73 months) and 26 ± 5 years (range, 16-46 years), respectively. Rowe and UCLA (University of California, Los Angeles) shoulder scores significantly improved from 42.0 ± 14.3 and 22.9 ± 3.2 preoperatively to 90.9 ± 15.4 and 32.5 ± 3.3 postoperatively in the Bankart group ( P < .001) and from 41.0 ± 17.9 and 22.3 ± 3.4 to 91.1 ± 16.1 and 32.3 ± 3.4 in the Latarjet group ( P < .001), respectively. There were no significant between-group differences in Rowe ( P = .920) or UCLA ( P = .715) scores at the final follow-up. Mean postoperative loss of motion during forward flexion, external rotation in abduction, and internal rotation to the posterior was 3.0° ± 6.2°, 11.6° ± 10.2°, and 0.6 spinal segment in the Bankart group and 3.7° ± 9.8°, 10.3° ± 12.8°, and 0.9 spinal segment in the Latarjet group, respectively. These differences were not significant. However, the loss of external rotation at the side was significantly greater in the Bankart group (13.3° ± 12.9°) than in the Latarjet group (7.3° ± 18.1°, P = .034). The overall recurrence rate was significantly higher in the Bankart group (22.9%) than in the Latarjet group (6.5%), ( P = .040). The Latarjet procedure and arthroscopic Bankart repair both provided satisfactory clinical outcome scores and pain relief for anterior shoulder instability with a borderline glenoid bone defect. However, the Latarjet procedure resulted in significantly lower recurrences and less external rotation limitation than the arthroscopic Bankart repair. Therefore, the Latarjet procedure could be a more reliable surgical option in anterior recurrent instability with a borderline glenoid bone defect.

Due to the highly organized tissue and avascular nature of the rotator cuff, rotator cuff tears have limited ability to heal after the tendon is reinserted directly on the greater tubercle of the humerus. Consequently, retears are among the most common complications after rotator cuff repair. Augmentation of rotator cuff repairs with patches has been an active area of research in recent years to reduce retear rate. Graft augmentation with 3D collagen could prevent retears of the repaired tendon and improve tendon-bone healing in moderate to large rotator cuff tears. Randomized controlled study; Level of evidence, 2. A prospective, randomized controlled study was performed in a consecutive series of 112 patients age 50 to 85 years who underwent rotator cuff repair with the suture-bridge technique (58 patients, control group) or the suture-bridge technique augmented with 3-dimensional (3D) collagen (54 patients, study group). All patients were followed for 28.2 months (range, 24-36 months). Visual analog scale score for pain, University of California Los Angeles (UCLA) shoulder score, and Constant score were determined. Magnetic resonance imaging was performed pre- and postoperatively (at a minimum of 24 months) to evaluate the integrity of the rotator cuff and the retear rate of the repaired tendon. Three patients in each group had biopsies at nearly 24 months after surgery with histological assessment and transmission electron microscopy. A total of 104 patients completed the final follow-up. At the 12-month follow-up, the UCLA shoulder score was 28.1 ± 1.9 in the study group, which was significantly better than that in the control group (26.9 ± 2.1, P = .002). The Constant score was also significantly better in the study group (87.1 ± 3.2) than in the control group (84.9 ± 4.2, P = .003). However, at the final follow-up, no significant differences were found in the UCLA shoulder scores (29.4 ± 1.9 in the control group and 30.0 ± 1.6 in the study group, P = .052) or Constant scores (89.9 ± 3.2 in the control group and 90.8 ± 3.5 in the study group, P = .18). In terms of structural integrity, more patients in the study group had a favorable type I retear grade (18/51) than in the control group (10/53) ( P = .06). The postoperative retear rate was 34.0% in the control group and 13.7% in the study group, thus indicating a significantly lower retear rate in the study group ( P = .02). Biopsy specimens of the tendon-bone interface in 6 patients revealed more bone formation and more aligned fibers with larger diameters in the study group than in the control group. No intraoperative or postoperative complications were noted in either group. 3D collagen augmentation could provide effective treatment of moderate to large rotator cuff tears, providing substantial functional improvement, and could reduce the retear rate. This technique could also promote new tendon-bone formation, thus exerting a prominent effect on tendon-bone healing.

Background: The optimal treatment of acute, complete dislocation of the acromioclavicular joint (ACJ) is still unresolved. Purpose: To determine the difference between operative and nonoperative treatment in acute Rockwood types III and V ACJ dislocation. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: In the operative treatment group, the ACJ was reduced and fixed with 2 transarticular Kirschner wires and ACJ ligament suturing. The Kirschner wires were extracted after 6 weeks. Nonoperatively treated patients received a reduction splint for 4 weeks. At the 18- to 20-year follow-up, the Constant, University of California at Los Angeles Shoulder Rating Scale (UCLA), Larsen, and Simple Shoulder Test (SST) scores were obtained, and clinical and radiographic examinations of both shoulders were performed. Results: Twenty-five of 35 potential patients were examined at the 18- to 20-year follow-up. There were 11 patients with Rockwood type III and 14 with type V dislocations. Delayed surgical treatment for ACJ was used in 2 patients during follow-up: 1 in the operatively treated group and 1 in the nonoperatively treated group. Clinically, ACJs were statistically significantly less prominent or unstable in the operative group than in the nonoperative group (normal/prominent/unstable: 9/4/3 and 0/6/3, respectively; P = .02) and in the operative type III (P = .03) but not type V dislocation groups. In operatively and nonoperatively treated patients, the mean Constant scores were 83 and 85, UCLA scores 25 and 27, Larsen scores 11 and 11, and SST scores 11 and 12 at follow-up, respectively. There were no statistically significant differences in type III and type V dislocations. In the radiographic analysis, the ACJ was wider in the nonoperative than the operative group (8.3 vs 3.4 mm; P = .004), and in the type V dislocations (nonoperative vs operative: 8.5 vs 2.4 mm; P = .007). There was no statistically significant difference between study groups in the elevation of the lateral end of the clavicle. Both groups showed equal levels of radiologic signs of ACJ osteoarthritis and calcification of the coracoclavicular ligaments. Conclusion: Nonoperative treatment was shown to produce more prominent or unstable and radiographically wider ACJs than was operative treatment, but clinical results were equally good in the study groups at 18- to 20-year follow-up. Both treatment methods showed statistically significant radiographic elevations of the lateral clavicle when compared with a noninjured ACJ. PMID:26535287

Clinical and Radiographic Outcomes With Assessment of the Learning Curve in Arthroscopically Assisted Latissimus Dorsi Tendon Transfer for Irreparable Posterosuperior Rotator Cuff Tears.

To evaluate the clinical results of an arthroscopy-assisted latissimus dorsi tendon transfer (aLD) for irreparable posterosuperior cuff tears as a primary surgery. The secondary aim of this study was to quantify the learning curve using the log-linear model. We hypothesized that aLD significantly improved shoulder function and that there was consistent reduction of the operative time in support of a learning-curve effect. After the arthroscopic partial repair was completed, the latissimus dorsi tendon was harvested via axillary mini-open incision and fixed with a knotless anchor arthroscopically. All patients were evaluated preoperatively and postoperatively using a modified University of California Los Angeles (UCLA) scoring system, active range of motion, and the visual analog scale (VAS) for pain. The operative time was recorded to quantify the learning curve using a log-linear model. Thirty patients with a mean age of 67.4 years who underwent aLD were included. At a mean of 34 months after an aLD, the mean UCLA score increased from 15.7 preoperatively to 28.8 postoperatively (P < .001). The mean active forward elevation increased from 105° preoperatively to 149° postoperatively (P < .001). The mean active external rotation increased from 22° preoperatively to 32° postoperatively (P < .001). The VAS improved from 58 mm to 18 mm (P < .001). In all but 2 cases (93%), the preoperative osteoarthritis grade was maintained. The mean operative time was 145 minutes. A significant linear correlation was observed between the operative time and cumulative volume of cases after performing a logarithmic transformation. The learning rate was calculated as 84%. Arthroscopy-assisted latissimus dorsi tendon transfer is a technically demanding procedure; however, it can lead to significant improvements in overall shoulder pain and function. This study also confirmed a learning-curve effect for the aLD. The learning rate was 84%, indicating the existence of a long learning period. Level IV, therapeutic case series.

This article examines the growing social phenomenon of elderly people living alone from 2 points of view: the objective loneliness of living alone and the subjective loneliness of feeling lonely. To validate the UCLA loneliness scale as a tool for the overall measurement of loneliness and to determine the social profile in elderly people living alone. Observational study carried out over 2 years (2012-2013) to identify elderly people living alone; case-control study to validate the UCLA loneliness scale. The sample was taken from 3 surgeries belonging to 2 Primary Care health centres from urban and rural areas. We studied construct validity, discriminant validity and sensitivity analysis were analysed. Of the elderly population studied 22.3% live alone, 61.7% due to loss of spouse, with a mean age of 70.7 years, and 82.7% women; 17.3% have no family ties and 63.2% feel lonely. UCLA loneliness scale has a construct validity with a high correlation between items. The discriminant validity was confirmed in relation to the elderly who do not live alone, with Cronbach alpha of 0.95, and it is sensitive to change. One in 4-5 elderly live alone, mainly due to the loss of spouse. There are 3 times as many women as men who live alone. Two out of 3 experience the feeling of loneliness. The UCLA loneliness scale has proved to be a useful and sensitive tool to measure loneliness in the elderly population. Copyright © 2015 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

To identify the complications concerning the use of metal anchors in shoulder arthroscopic procedures. Methods: 28 shoulders of 28 patients (23 male and 5 female) have been re-operated in the period between December 1997 and August 2007, at Hospital Ortopédico, Belo Horizonte Hospital and Military Police Hospital in Belo Horizonte, MG, as a result of complications such as loose anchors and prominent anchors. The primary surgeries intended to treat 20 anterior traumatic instabilities (71.5%), one posterior instability (3.5%), one slap injury (3.5%), six procedures for treating injuries on the rotator cuff (21.5%). We used the X-ray classification suggested by Samilson and Prieto and Outerbridge arthroscopic classification for assessing patients' degree of arthrosis. All patients were evaluated by the UCLA (University of California at Los Angeles) index criteria. Results: In all patients, arthroscopic reviews were made. In two cases, after anchors removal, clinical signs of instability were seen, leading to the decision of providing open stabilization by Latarjet-Patte technique. Conclusion: the complications with metallic-suture anchors result from inappropriate surgical techniques applied in arthroscopy. PMID:26998465

Duke, Danny; Krishnan, Mohan; Faith, Melissa; Storch, Eric A

2006-01-01

This study examined the psychometric properties of the Brief Fear of Negative Evaluation (BFNE) Scale in a nonclinical, nonstudent sample. Participants were administered the BFNE Scale, Beck Depression Inventory (BDI), and the UCLA Loneliness Scale. No differences were found across age, but women scored significantly higher on the BFNE Scale than men. Confirmatory factor analysis supported a two-factor solution corresponding to positive and reverse scored items. Internal consistency was excellent for the positive scored factor (alpha=.94), acceptable for the reverse scored factor (alpha=.73), and good for the full BFNE Scale (alpha=.80). BFNE scores were significantly correlated in the expected directions with the BDI and the UCLA Loneliness Scale. Implications of these findings for clinical practice and future research are discussed.

Generalized joint laxity has been proposed as a significant risk factor for failure after arthroscopic anterior shoulder stabilization. The purpose of this study was to prospectively measure joint mobility in patients undergoing arthroscopic anterior shoulder stabilization and to determine whether hypermobility is a risk factor for worse outcomes compared with patients having normal joint mobility. Patients with anterior shoulder instability were prospectively enrolled. Generalized joint hypermobility was measured using the Beighton Hypermobility Score and the Rowe, UCLA, SANE, SST, and WOSI scores were administered and reported as patient outcomes preoperatively and following arthroscopic anterior shoulder stabilization at 6 weeks, 6 months, 12 months, and 24 months postoperatively. Patients were stratified into two groups based on their Beighton Hypermobility Score, with scores ≥ 4/9 indicative of joint hypermobility. Sixteen patients with joint hypermobility (JH) and 18 non-hypermobile patients (NJH) were enrolled. At baseline, there were no significant differences in demographic characteristics or baseline patient-reported outcomes. Significantly more patients in the NJH group had SLAP tears (n = 10) compared to the JH group (n = 2) (p = .013). At all follow-up times, there were no significant differences between the NJH and JH groups with regard to patient-reported outcome scores (p > .05). In the JH group, 17% of patients reported recurrent instability at two years postoperatively compared to 25% of patients in the NJH group. There was no significant difference in failure rate (p = .67). There was no significant difference in patient-reported outcomes or recurrent instability in patients with versus without joint hypermobility undergoing arthroscopic anterior shoulder stabilization.

To examine the measurement properties and factor structure of the short version of the Revised University of California Los Angeles (R-UCLA) loneliness scale from the Health and Retirement Study (HRS). Based on data from 3,706 HRS participants aged 65 + who completed the 2012 wave of the HRS and its Psychosocial Supplement, the measurement properties and factorability of the R-UCLA were examined by conducting an exploratory factor analysis (EFA) and the confirmatory factor analysis (CFA) on randomly split halves. The average score for the 11-item loneliness scale was 16.4 (standard deviation: 4.5). An evaluation of the internal consistency produced a Cronbach's α of 0.87. Results from the EFA showed that two- and three-factor models were appropriate. However, based on the results of the CFA, only a two-factor model was determined to be suitable because there was a very high correlation between two factors identified in the three-factor model, available social connections and sense of belonging. This study provides important data on the properties of the 11-item R-UCLA scale by identifying a two-factor model of loneliness: feeling isolated and available social connections. Our findings suggest the 11-item R-UCLA has good factorability and internal reliability. Copyright © 2017 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

Ideberg type III glenoid fractures with associated superior shoulder suspensory complex (SSSC) injuries are rare, and related treatments have not been reported in the literature. The purpose of this study was to evaluate the clinical outcomes of such injuries treated with open reduction and internal fixation (ORIF). Between July 2007 and April 2012, ten patients with Ideberg type III glenoid fractures were surgically treated using ORIF with 2 cannulated screws or a screw combined with a metacarpal plate through an anterior approach. Patients with associated SSSC injuries underwent ORIF with K-wires or plates. Information was available for 9 patients with a mean follow-up of 24.1±18.2 months. Mean bone-healing time was 8.4±2.2 weeks. At last follow-up, mean forward flexion of the operative shoulder was 157.8°±7.5°, mean external rotation was 62.9°±7.9°, and mean internal rotation was thoracic level T6±0.8. Mean Constant score was 84.1±3.7 points, which was a mean of 92.7%±3.4% of that seen in the contralateral shoulder. Mean UCLA score and Disabilities of the Arm, Shoulder and Hand score were 33.6±1.7 and 16.6±7.7, respectively. The results show that Ideberg type III glenoid fractures with associated SSSC injuries can be successfully treated using ORIF through an anterior approach. Glenoid fractures and SCCC injuries should be treated simultaneously. Copyright 2013, SLACK Incorporated.

To evaluate the integrity of the subscapularis tendon by strength, function and magnetic resonance imaging after deltopectoralis access for anterior shoulder instability. 20 patients with anterior shoulder instability have been evaluated. Minimum follow-up was 12 months, with a mean of 40 months. Only male patients were included, with a mean of age of 29 years (20 - 42 years). The patients have been submitted to physical examinations of mobility, muscular strength, Belly Test and Gerber Test. The isokinetic strength in internal and external rotation, in angular speeds of 60(0)/s and 180(0)/s, for both shoulders was measured using a dynamometer. In 15 patients magnetic resonance imaging (MRI) was carried out on both shoulders for evaluating the thickness, cross-sectional area and atrophy of the subscapularis muscle. A significant difference was found between torque peaks at the speed of 60(0)/s for internal (p=0.036) and external (p=0.008) rotation. However, at 180(0)/s the opposite happens (internal rotation: p=0.133; external rotation: p=0.393). Subscapularis muscle thickness and area are significantly smaller than the normal side, with a deficit of 19% and 23%, respectively. According to Rowe and UCLA scores, we find excellent and good results for the majority of patients, with a mean of 88 and 31.6 points, respectively. Despite of the good functional results, open surgery can limit strength and reduce the thickness and the cross-sectional area of subscapularis muscle. However, the best results were found in the patients who had the dominant side operated.

Few studies of large-to-massive contracted rotator cuff tears have examined the arthroscopic complete repair obtained by a posterior interval slide and whether the clinical outcomes or structural integrity achieved are better than those after partial repair without the posterior interval slide. The study included forty-one patients with large-to-massive contracted rotator cuff tears, not amenable to complete repair with margin convergence alone. The patients underwent either arthroscopic complete repair with a posterior interval slide and side-to-side repair of the interval slide edge (twenty-two patients; Group P) or partial repair with margin convergence (nineteen patients; Group M). The patient assignment was not randomized. The Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) score, University of California at Los Angeles (UCLA) shoulder score, and range of motion were used to compare the functional outcomes. Preoperative and six-month postoperative magnetic resonance arthrography (MRA) images were compared within or between groups. At the two-year follow-up evaluation, the SST, ASES score, UCLA score, and range of motion had significantly improved (p < 0.001 for all) in both groups. However, no significant differences were detected between groups. Even though the difference in preoperative tear size on MRA images was not significant, follow-up MRA images identified a retear in twenty patients (91%) in Group P and a significant difference in tear size between groups (p = 0.007). The complete repair group with an aggressive release had no better clinical or structural outcomes compared with the partial repair group with margin convergence alone for large-to-massive contracted rotator cuff tears. In addition, the complete repair group had a 91% retear rate and a greater defect on follow-up MRA images. Even though this study had a relatively short-term follow-up, a complete repair of large-to-massive contracted rotator cuff tears, with an aggressive release such as posterior interval slide, may not have an increased benefit compared with partial repair without posterior interval slide.

The purpose of this study was to appraise the retear rate and clinical outcomes of platelet-rich plasma use in patients undergoing arthroscopic full-thickness rotator cuff repair. We searched the Cochrane Library, PubMed, and EMBASE databases for randomized controlled trials comparing the outcomes of arthroscopic rotator cuff surgery with or without the use of platelet-rich plasma. Methodological quality was assessed by the Detsky quality scale. When there was no high heterogeneity, we used a fixed-effects model. Dichotomous variables were presented as risk ratios (RRs) with 95% confidence intervals (CIs), and continuous data were measured as mean differences with 95% CIs. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the quality of evidence for each individual outcome. Eight randomized controlled trials were included, with the sample size ranging from 28 to 88. Overall methodological quality was high. Fixed-effects analysis showed that differences were not significant between the 2 groups in retear rate (RR, 0.94; 95% CI, 0.70 to 1.25; P = .66), Constant score (mean difference, 1.12; 95% CI, -1.38 to 3.61; P = .38), and University of California at Los Angeles (UCLA) score (mean difference, -0.68; 95% CI, -2.00 to 0.65; P = .32). The strength of GRADE evidence was categorized respectively as low for retear, moderate for Constant score, and low for UCLA shoulder score. Our meta-analysis does not support the use of platelet-rich plasma in the arthroscopic repair of full-thickness rotator cuff tears over repairs without platelet-rich plasma because of similar retear rates and clinical outcomes.

Rotator cuff tear is a common problem either after trauma or after degenerative tear in old age group. Arthroscopic repair is the current concept of rotator cuff repair. Here, we are trying to evaluate the functional outcome after arthroscopic repair of full thickness rotator cuff tear (single row) in Indian population. Twenty five patients (14 males and 11 females) who underwent arthroscopic repair of full thickness rotator cuff tear at a single institution were included in the study. Postoperatively patient's shoulder was rated according to UCLA score, pain was graded according to the visual analog score. The range of motion was analysed and documented. The mean age of the patients were 50.48 years. The preoperative VAS score mode was 7 and post operative VAS was 1 (p value <0.001). The UCLA grading was good in 80% (n = 20), fair in 12% (n = 3), excellent in 8% (n = 2) and poor results were seen in none of the patients. The mean UCLA improved from a score of 15.84 to 30.28 with a p value <0.001. Mean postoperative forward flexion was 161.6°, mean abduction was 147.6° and mean external rotation was 45.4°. Arthroscopic repair is a good procedure for full thickness rotator cuff tear with minimal complications. The newer double row repair claims to be biomechanically superior with faster healing rates without functional advantages, hence we used a single row repair considering the Indian population and the cost effectiveness of the surgery with good to excellent results.

Psoriasis is a common, long-term skin disease associated with high levels of psychological distress and a considerable adverse impact on life. The effects of psoriasis, beyond skin affliction, are seldom recognized and often undertreated. The aim of the study is to evaluate the quality of life, anxiety and depression, self-esteem and loneliness in patients with psoriasis. Eighty-four patients with psoriasis were enrolled in the study. The quality of life, depression and anxiety, loneliness and self-esteem of the patient were assessed using the Dermatology Life Quality Index, Hospital Anxiety and Depression Scale, the UCLA loneliness Scale (UCLA-Version 3) and Rosenberg's Self-esteem Scale, respectively. The Dermatology Quality of Life Index score among psoriasis patients was 12.61 ± 4.88. They had statistically significantly higher scores according to the Hospital Anxiety and Depression Scale -anxiety subscale (p=0.032)-compared with healthy volunteers. Moreover, a statistically significant difference was found between the two groups concerning the UCLA-scale (p=0.033) and RSES-scale (p<0.0001). Female patients presented with lower self-esteem than male patients. Psoriasis is a distressing, recurrent disorder that significantly impairs quality of life. Therefore, the recognition and future management of psoriasis may require the involvement of multi-disciplinary teams to manage the physical, psychological and social aspects of the condition, as is the case for systemic, long-term conditions.

We aimed to perform a systematic review to identify factors that may lead to poorer outcomes in arthroscopic surgery for posterior shoulder instability. We searched MEDLINE, Embase and the Cochrane Database of Systematic Reviews for 757 unique articles. We eventually included 22 articles. Data were analysed using Review Manager 5.3. The presence of chondral damage was associated with poorer outcomes as reflected in a higher post-operative Quick Disabilities of theArm, Shoulder and Hand score (mean difference (MD) = 17.1; 95% confidence interval (CI) = 2.82-31.4; p = 0.02), higher WesternOntario Shoulder Instability (WOSI) index (MD = 468.0; 95% CI = 136.5-799.5; p = 0.006), lower Simple Shoulder Test score (MD = -2.40; 95% CI = -4.34 to -0.46; p = 0.02) and a lower Single Assessment Numeric Evaluation score (MD = -15.4; 95% CI = -30.6 to -0.23; p = 0.05). The presence of previous shoulder surgery was associated with poorer outcomes as depicted by a lower American Shoulder and Elbow Society (ASES) score (MD = -93.1; 95% CI = -96.9 to -89.3; p < 0.0001). The availability of workers' compensation was associated with poorer outcomes as revealed by a lower rate of return to work (odds ratio (OR) = 0.02; 95% CI = 0.00-0.20; p = 0.0008). The presence of additional procedures while performing surgery for posterior shoulder instability was associated with poorer outcomes as reflected by lower ASES scores (MD = -6.70; 95% CI = -8.64 to -4.76; p < 0.0001), higher WOSI index (MD = 63.4; 95% CI = 33.0-93.8; p < 0.0001), lower University of California at Los Angeles (UCLA) scores (MD = -2.30; 95% CI = -2.81 to -1.79; p < 0.0001), higher pain scores (MD = 0.72; 95% CI = 0.39-1.05; p < 0.0001) and higher post-operative instability (MD = 0.80; 95% CI = 0.57-1.03; p < 0.0001). The presence of chondral damage, previous shoulder surgery, concomitant surgery and workman's compensation was associated with poorer outcomes for arthroscopic repair of posterior shoulder instability. Further studies should be done to further validate these factors.

Local application of autologous platelet rich plasma (PRP) improves tendon healing in patients undergoing arthroscopic rotator cuff repair. Prospective, randomized, controlled, double blind study; considering an alpha level of 5%, a power of 80%, 22 patients for group are needed. Fifty-three patients who underwent shoulder arthroscopy for the repair of a complete rotator cuff tear were randomly divided into 2 groups, using a block randomization procedure. A treatment group (N = 26) consisted of those who received an intraoperative application of PRP in combination with an autologous thrombin component. A control group (N = 27) consisted of those who did not receive that treatment. Patients were evaluated with validated outcome scores. A magnetic resonance image (MRI) was performed in all cases at more than 1 year post-op. All patients had the same accelerated rehabilitation protocol. The 2 groups were homogeneous. The pain score in the treatment group was lower than the control group at 3, 7, 14, and 30 days after surgery (P < .05). On the Simple Shoulder Test (SST), University of California (UCLA), and Constant scores, strength in external rotation, as measured by a dynamometer, were significantly higher in the treatment group than the control group at 3 months after surgery (strength in external rotation [SER]: 3 ± 1.6 vs 2.1 ± 1.3 kg; SST: 8.9 ± 2.2 vs 7.1 ± 2.7; UCLA: 26.9 ± 3 vs 24.2 ± 4.9; Constant: 65 ± 9 vs 57.8 ± 11; P < .05). There was no difference between the 2 groups after 6, 12, and 24 months. The follow-up MRI showed no significant difference in the healing rate of the rotator cuff tear. In the subgroup of grade 1 and 2 tears, with less retraction, SER in the PRP group was significant higher at 3, 6, 12, and 24 months postoperative (P < .05). The results of our study showed autologous PRP reduced pain in the first postoperative months. The long-term results of subgroups of grade 1 and 2 tears suggest that PRP positively affected cuff rotator healing. Copyright © 2011 Journal of Shoulder and Elbow Surgery Board of Trustees.

To identify all available shoulder disability questionnaires designed to measure physical functioning and to examine those with satisfactory clinimetric quality. We used the Medline database and the "Guide des outils de mesure de l'évaluation en médecine physique et de réadaptation" textbook to search for questionnaires. Analysis took into account the development methodology, clinimetric quality of the instruments and frequency of their utilization. We classified the instruments according to the International Classification of Functioning, Disability and Health. Thirty-eight instruments have been developed to measure disease-, shoulder- or upper extremity-specific outcome. Four scales assess upper-extremity disability and 3 others shoulder disability. We found 6 scales evaluating disability and shoulder pain, 7 scales measuring the quality of life in patients with various conditions of the shoulder, 14 scales combining objective and subjective measures, 2 pain scales and 2 unclassified scales. Older instruments developed before the advent of modern measurement development methodology usually combine objective and subjective measures. Recent instruments were designed with appropriate methodology. Most are self-administered questionnaires. Numerous shoulder outcome measure instruments are available. There is no "gold standard" for assessing shoulder function outcome in the general population.

This study aimed to evaluate the clinical outcomes and structural integrity of arthroscopic repair of intratendinous rotator cuff tear. Patients who were diagnosed with an intratendinous tear but in whom conservative treatment failed were selected and underwent arthroscopic repair. Between 2008 and 2014, a total of 30 patients (6 men, 24 women; mean age, 59 ± 3.7 years) met the inclusion criteria and were followed up. The mean follow-up period was 26.3 ± 0.7 months. The results were evaluated using the University of California at Los Angeles (UCLA) score, the Society of the American Shoulder and Elbow Surgeons rating scale (ASES) questionnaire, and the visual analog scale (VAS) and range of motion (ROM) were measured preoperatively and at final follow-up. Magnetic resonance imaging (MRI) was performed preoperatively and at 6.7 ± 0.2 months postoperatively. Postoperative MRI was performed on 27 out of 30 patients and analysed using the Sugaya classification. Corresponding to the preoperative MRI findings, arthroscopic findings of intratendinous tears were observed in all 30 patients. The mean active forward elevation ROM was 137.3° ± 15.4° before surgery and 168.8° ± 15.2° at the final follow-up. The internal and external rotations at abduction were 31.7° ± 5.1° and 63.0° ± 11.6° before surgery, respectively, and 60.5° ± 8.0° and 75.2° ± 10.8° after surgery, respectively. The UCLA score improved from of 20.1 ± 7.4 points preoperative to 28.4 ± 5.5 points at the final follow-up. The ASES score improved from 55.7 ± 15.3 points preoperative to 82.6 ± 9.7 points postoperatively. The VAS for pain score decreased from 6.4 ± 1.2 points preoperative to 1.6 ± 0.9 points postoperative. Satisfactory outcomes (excellent/good) in terms of UCLA and ASES scores were observed in 29 of 30 patients. Based on Sugaya classification, grades I, II, and III structural integrities were observed in 9, 14, and 4 patients, respectively. Successful clinical outcomes and structural integrity can be achieved with arthroscopic repair of intratendinous rotator cuff tears involving more than half thickness (> 50%). Therefore, arthroscopic repair is a practical next treatment option for patients with intratendinous rotator cuff tears in whom conservative treatment fails. IV.

Persistent or recurrent glenohumeral instability after a previous operative stabilization can be a complex problem. Our aim is to establish the incidence of recurrence and its revision surgery, and to analyse the functional results of the revision instability surgery, as well as to determine surgical protocols to perform it. A retrospective analysis was conducted on 16 patients with recurrent instability out of 164 patients operated on between 1999 and 2011. The mean follow-up was 57 months and the mean age was 29 years. To evaluate functional outcome we employed Constant, Rowe, UCLA scores and the visual analogue scale. Of the 12 patients who failed the initial arthroscopic surgery, 6 patients underwent an arthroscopic antero-inferior labrum repair technique, 4 using open labrum repair techniques, and 2 coracoid transfer. The two cases of open surgery with recurrences underwent surgery for coracoid transfer. Results of the Constant score were excellent or good in 64% of patients. Surgical revision of instability is a complex surgery essentially for two reasons: the difficulty in recognising the problem, and the technical demand (greater variety and the increasingly complex techniques).

Objectives: The purpose of this study is to report the clinical outcomes of patients undergoing an arthroscopic rotator cuff repair with and without acromioplasty at a minumul of two year follow-up. Methods: Patients undergoing arthroscopic repair of full thickness rotator cuff tears were randomized into acromioplasty or non-acromioplasty groups. Pre-operatively, validated outcome scores including the Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons score (ASES), UCLA score, and SF-12 health assessment were collected along with physical examination including range of motion and dynamometer strength testing. Pre-operative imaging was also reviewed to classify the acromial morphology, acromial angle, and lateral acromial angulation. Intra-operative data including tear size, repair configuration, and concomitant procedures were recorded. Postoperatively, data was collected at 6 weeks, 6 months, one year and at two years. Results are reported as mean ± standard deviation. Student’s t-test was utilized for statistical analysis with an alpha value of 0.05 set as significant. Results: Sixty-one patients completed surveys pre- and post-operatively at a mean 2.6 years. All patients had at least two year follow-up. Thirty-five patients with an average age of 58.4 years (range 44.4 - 74.7) were randomized to the acromioplasty group (22 male, 13 female) and 26 patients with a mean age of 58.2 years (range 42.9-77.0) to the non-acromioplasty group (17 male, 9 female). All outcome scores improved significantly (p < 0.05) in both groups from pre- to post-operatively at two year follow-up. In the acromioplasty group, improvements were observed for SST (5.6 ± 2.7 to 10.7 ± 1.7), ASES (53.5 ± 16.8 to 91.0 ± 13.5) and UCLA (10.7 ± 3.1 to 17.9 ± 30.0) scores. In the non-acromioplasty group, SST increased from 5.6 ± 3.1 to 10.5 ± 2.2; ASES from 58.9 ± 19.1 to 93.5 ± 10.8, and UCLA from 12.0 ± 2.8 to 17.4 ± 3.7. There was no statistical difference in clinical outcome when comparing the groups. Conclusion: The results of this study demonstrate no difference in clinical outcomes following rotator cuff repair with or without acromioplasty at two years postoperatively. These data suggest that acromioplasty may not need to be performed following rotator cuff repair, particularly in the setting of normal acromial architecture.

Chronic leg ulcers are a public health problem that can have a significant impact on the patient's physical, socioeconomic and psychological status. The aim of this study is to evaluate the quality of life, anxiety and depression, self-esteem and loneliness in patients suffering from leg ulcers. A total of 102 patients were enrolled in the study. The quality of life, anxiety and depression, self-esteem and loneliness of the patient were assessed using the Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), Rosenberg's Self-esteem Scale (RSES) and the UCLA Loneliness Scale (UCLA-Version 3), respectively. The mean DLQI score was 13·38 ± 2·59, suggesting a serious effect on the quality of life of patients. Those with leg ulcers had statistically significant higher scores according to the HADS-total scale (P = 0·031) and HADS-anxiety subscale (P = 0·015) compared with healthy volunteers. Moreover, a statistically significant difference was found between the two groups concerning the UCLA-scale (P = 0·029). Female patients presented with a higher score of anxiety (P = 0·027) and social isolation (P = 0·048), and worse quality of life (P = 0·018) than male patients. A severe quality of life impairment was documented, reflecting a significant psychosocial impact on patients with leg ulcers. © 2014 The Authors.

69 women and 42 men responded to the Coopersmith Self-esteem Inventory, the Revised UCLA Loneliness Scale, the Hong Psychological Reactance Scale, and the Famous Sayings test. Also, subjects rated their happiness using a Likert scale. Men scored significantly higher than did women on the UCLA Loneliness, Hostility, and Psychological Reactance measures, and lower on the Conventional Mores and Social Acquiescence measures. Loneliness scores positively correlated with Psychological Reactance scores and negatively with Self-esteem and Conventional Mores scores and with happiness self-ratings for both sexes. Men who scored higher on Psychological Reactance tended to score lower on Conventional Mores. Happiness ratings correlated negatively with Psychological Reactance for all subjects and positively with Conventional Mores for men subjects only. Women's self-esteem scores correlated positively with self-ratings of happiness and negatively with Psychological Reactance, Hostility, and Fear of Failure. Finally, women's Psychological Reactance scores correlated positively with those on Bass's Fear of Failure scale.

To identify all available shoulder disability questionnaires and to examine those that could be used for athlete. We systematically reviewed the literature in Medline using the keywords shoulder, function, scale, index, score, questionnaire, disability, quality of life, assessment, and evaluation. We searched for scales used for athletes with the keywords scale name AND (sport OR athlete). Data were completed by using the "Guide des Outils de Mesure et d'Evaluation en Médecine Physique et de Réadaptation" textbook. Analysis took into account the clinimetric quality of the instruments and the number of items specifically related to sports. A total of 37 instruments have been developed to measure disease-, shoulder-specific or upper extremity specific outcome. Older instruments were developed before the advent of modern measurement methods. They usually combined objective and subjective measures. Recent instruments were designed with use of more advanced methods. Most are self-administered questionnaires. Fourteen scales included items assessing sport activity. Four of these scales have been used to assess shoulder disability in athlete. Six scales have been used to assess such disability but do not have specific items related to sports. There is no gold standard for assessing shoulder outcome in the general population and no validated outcome instruments specifically for athletes. We suggest the use of ASES, WOSI and WORC scales for evaluating shoulder function in the recreational athletes. The DASH scale should be evaluated in this population. The principal criterion in evaluating shoulder function in the high level athlete is a return to the same level of sport performance. Further studies are required to identify measurement tools for shoulder disability that have a high predictive value for return to sport.

Pain and psychological well-being of older persons living in nursing homes: an exploratory study in planning patient-centred intervention.

This article is a report on a study to examine the pain situation, the use of oral analgesics and non-pharmacological strategies and the psychological well-being of older patients living in nursing homes; the relationships between pain and psychological well-being were also explored. Pain is common among older adults world-wide, and tends to be under-treated. Indeed, the high prevalence of pain may further hinder the fulfilment of psychological needs in a Maslow hierarchy of needs model. It was a quantitative cross-sectional study; older adults from six nursing homes were invited to join the study in 2007-2009, with a response rate of 100%. Pain was measured using the Geriatric Pain Assessment, happiness using the Subjective Happiness Scale, life satisfaction using the Life Satisfaction Index - A Form, loneliness using the Revised UCLA Loneliness Scale and depression was measured using the Geriatric Depression Scale. A convenience sample of 302 older patients (213 females and 89 males aged from 60 to 101, mean age of 84·99) joined the study. The majority of them had experienced pain in the previous 3 months, with a pain intensity of 4·51 on a 10-point scale. Pain sites were mainly the knee, back, shoulder and musculoskeletal areas. Only 50% of them took oral analgesics, and 70% used non-pharmacological measures for pain relief. The pain group reported significantly more loneliness and depression when compared with their no-pain counterparts. As the number of older patients increases, so does the need for alternative accommodation; thus, pain management education is urgently needed for staff and nursing home residents. © 2011 The Authors.

To verify whether a shoulder exercises program according to Bobath reduced the shoulder pain in hemiplegic patients. We studied a total of 20 patients with pain shoulder. Ten patients are assigned to group R (submitted to rehabilitation) and ten to group R+E (submitted to rehabilitation and shoulder exercises program according to Bobath). Shoulder exercises program was self-performed by the patients after training in occupational rehabilitation unit. The assessment of patients was performed at admission to hospital, at discharge and three months after discharge. Shoulder pain (VAS), shoulder range of motion, disability (FIM), motor function (Fugl-Meyer scale) and spasticity (Ashworth scale) of paretic arm were evaluated in all patients. VAS was similar in both groups at admission and decreased in group R+E at discharge without reaching significant differences (p=0.253). On the contrary, VAS and Shoulder range of motion improved statistically in group R+E (p=0.0001, p<0.04 respectively) after three months. The others variables measured did not change. This study showed that a shoulder exercises program according to Bobath reduces shoulder pain of patients with hemiplegia if it is performed daily and for a long period of time.

Patient-reported outcome measures have increasingly accompanied objective examination findings in the evaluation of orthopaedic interventions. Our objective was to determine whether a validated measure of mental health (Short Form-36 Mental Component Summary [SF-36 MCS]) or measures of tear severity on magnetic resonance imaging were more strongly associated with self-assessed shoulder pain and function in patients with symptomatic full-thickness rotator cuff tears. One hundred and sixty-nine patients with full-thickness rotator cuff tears were prospectively enrolled. Patients completed the Short Form-36, visual analog scales for shoulder pain and function, the Simple Shoulder Test (SST), and the American Shoulder and Elbow Surgeons (ASES) instrument at the time of diagnosis. Shoulder magnetic resonance imaging examinations were reviewed to document the number of tendons involved, tear size, tendon retraction, and tear surface area. Age, sex, body mass index, number of medical comorbidities, smoking status, and Workers' Compensation status were recorded. Bivariate correlations and multivariate regression models were calculated to identify associations with baseline shoulder scores. The SF-36 MCS had the strongest correlation with the visual analog scale for shoulder pain (Pearson correlation coefficient, -0.48; p < 0.001), the visual analog scale for shoulder function (Pearson correlation coefficient, -0.33; p < 0.001), the SST (Pearson correlation coefficient, 0.37; p < 0.001), and the ASES score (Pearson correlation coefficient, 0.51; p < 0.001). Tear severity only correlated with the visual analog scale for shoulder function; the Pearson correlation coefficient was 0.19 for tear size (p = 0.018), 0.18 for tendon retraction (p = 0.025), 0.18 for tear area (p = 0.022), and 0.20 for the number of tendons involved (p = 0.011). Tear severity did not correlate with other scores in bivariate correlations (all p > 0.05). In all multivariate models, the SF-36 MCS had the strongest association with the visual analog scale for shoulder pain, the visual analog scale for shoulder function, the SST, and the ASES score (all p < 0.001). Patient mental health may play an influential role in patient-reported pain and function in patients with full-thickness rotator cuff tears. Further studies are needed to determine its effect on the outcome of the treatment of rotator cuff disease. Copyright © 2016 by The Journal of Bone and Joint Surgery, Incorporated.

Constant's Shoulder Scale is a validated and widely applied instrument for assessment of shoulder function. We used this instrument to assess which treatment and demographic variables contribute to shoulder dysfunction after neck dissection in head and neck cancer patients. A convenience sample of 54 patients with 64 neck dissections and minimum follow-up of 11 months were evaluated. Thirty-two accessory nerve-sparing modified radical (MRND) and 32 selective neck (SND) dissections were performed. Multivariable regression analysis was used to determine the variables that were predictive for shoulder dysfunction. Clinical variables included age, time from surgery, handedness, weight, radiation therapy, neck dissection type, tumor stage, and site. Patients receiving MRND had significantly worse shoulder function than patients with SND (p =.0007). Radiation therapy contributed negatively, whereas weight contributed positively (p =.0001). The critical factors contributing to shoulder dysfunction after neck dissection were weight, radiation therapy, and neck dissection type. Copyright 2002 Wiley Periodicals, Inc.

2011-02-01

The purpose of this study was to determine and compare the efficacy of kinesio tape and physical therapy modalities in patients with shoulder impingement syndrome. Patients (n = 55) were treated with kinesio tape (n = 30) three times by intervals of 3 days or a daily program of local modalities (n = 25) for 2 weeks. Response to treatment was evaluated with the Disability of Arm, Shoulder, and Hand scale. Patients were questioned for the night pain, daily pain, and pain with motion. Outcome measures except for the Disability of Arm, Shoulder, and Hand scale were assessed at baseline, first, and second weeks of the treatment. Disability of Arm, Shoulder, and Hand scale was evaluated only before and after the treatment. Disability of Arm, Shoulder, and Hand scale and visual analog scale scores decreased significantly in both treatment groups as compared with the baseline levels. The rest, night, and movement median pain scores of the kinesio taping (20, 40, and 50, respectively) group were statistically significantly lower (p values were 0.001, 0.01, and 0.001, respectively) at the first week examination as compared with the physical therapy group (50, 70, and 70, respectively). However, there was no significant difference in the same parameters between two groups at the second week (0.109, 0.07, and 0.218 for rest, night, and movement median pain scores, respectively). Disability of Arm, Shoulder, and Hand scale scores of the kinesio taping group were significantly lower at the second week as compared with the physical therapy group. No side effects were observed. Kinesio tape has been found to be more effective than the local modalities at the first week and was similarly effective at the second week of the treatment. Kinesio taping may be an alternative treatment option in the treatment of shoulder impingement syndrome especially when an immediate effect is needed.

The aim of this study was to analyze the clinical and functional results of hook plate fixation in Neer type 2 distal clavicle fractures. We retrospectively analyzed 16 patients (11 males, 5 females) who were diagnosed with Neer type 2 distal clavicle fractures and treated with hook plate fixation between 2013 and 2014. Mean age was 38 (range: 27-61), and mean follow-up time was 14.3 (range: 12-18) months. Complications seen on radiographs were implant failure and subacromial osteolysis. The clinical results were evaluated with modified UCLA (University of California Los Angeles) scoring system. Bone union was achieved in all patients at the end of the first 4 months. Mean modified UCLA score was 32.75 (range 31-35). In 12 patients (68%), the implants had to be removed due to complications. After removal, the complaints regressed and shoulders' range of motion increased. Clinical and radiological results on the fixation of Neer type 2 distal clavicle fractures with a hook plate are good in terms of fracture union and function. The major disadvantage of the method was the requirement of early implant removal due to the hardware related complications and good results can be achieved only after plate removal. Optimizing the length of hook plate may lower the rate of complications. Level IV, Therapeutic study. Copyright © 2016 Turkish Association of Orthopaedics and Traumatology.

The main goal of this study was to propose and validate a tool to quantify the psychological readiness of athletes to return to sport following traumatic shoulder instability and conservative or surgical management. «Knee» was replaced by the term «shoulder» in the Anterior Cruciate Ligament-Return to Sport after Injury scale. This pilot test of the Shoulder Instability-Return to Sport after Injury scale (SIRSI) was performed in a group of athletes who underwent surgery for post-traumatic chronic anterior shoulder instability. The final version was then validated according to the international COSMIN methodology. A retrospective study was performed including all rugby players who had reported an episode of instability between 2012 and 2013. The WOSI and the Walch-Duplay scales were used as reference questionnaires. Sixty-two patients were included, mean age 26 ± 5.2 years old, 5 women/57 men. Patients were professional or competitive athletes (70.9%) and followed-up for 4.6 ± 1.6 years after the first episode of shoulder instability. Shoulder surgery was performed in 30/62 (48.4%) patients, a mean 1.6 ± 1.2 years after the first episode of instability. The SIRSI was strongly correlated with the reference questionnaires (r = 0.80, p < 10 -5 ). The mean SIRSI score was significantly higher in patients who returned to play rugby (60.9 ± 26.6% vs 38.1 ± 25.6%, p = 0.001). The internal consistency of the scale was high (α = 0.96). Reproducibility of the test-retest was excellent (ρ = 0.93, 95% CI [0.89-0.96], p < 10 -5 ). No ceiling/floor effects were found. The SIRSI is a valid, reproducible scale that identifies patients who are ready to return to the same sport after an episode of shoulder instability, whether they undergo surgery or not. III.

This study examined the effectiveness of manipulation under ultrasound-guided brachial plexus block in patients with recalcitrant idiopathic frozen shoulder and diabetic secondary frozen shoulder (diabetic frozen shoulder). Forty-four idiopathic frozen shoulders and 10 diabetic frozen shoulders with failed conservative treatment for at least 3 months were included in this study. The manipulation was performed under ultrasound-guided brachial plexus block and visual analogue scale, range of motion, and Constant scores were measured before manipulation and at the last follow-up examination. No major complications were observed during the procedure. Sufficient improvement was not obtained in two patients during the procedure and to avoid complications, the procedure was discontinued and subsequently arthroscopic capsular release was performed. Visual analogue scale, range of motion towards all directions, and Constant scores were significantly improved after the manipulation in both the idiopathic frozen shoulder and diabetic frozen shoulder groups, however the diabetic group showed inferior results compared with those of the idiopathic group. This manipulation was effective and shortened the duration of symptoms in most of the idiopathic and diabetic frozen shoulders without major complications during the procedure. Diabetic frozen shoulder showed inferior clinical results and difficulty in recovery in range of motion, which indicated that diabetic frozen shoulder should be discussed as a different entity.

Children with obstetrical brachial plexus injury often develop an internal rotation and adduction contracture about the shoulder as a secondary deformity, resulting in an inability to externally rotate and abduct the shoulder. The Hoffer procedure is evaluated for its potential benefit in improving shoulder abduction and external rotation and its impact on activities of daily living. This is a retrospective review of patients treated in brachial plexus injury clinic who underwent tendon transfer procedures about the shoulder. Preoperative and postoperative active movement and active range of motion were measured and recorded using the Mallet scale and the Active Movement Scale. Twenty patients were included in the study. Average age at time of surgery was 6.35 years. Thirteen patients had primary brachial plexus reconstructive surgery and four patients had concomitant wrist extension tendon transfer procedures. All patients had full passive range of motion preoperatively. The average follow-up period was 25.45 months. Average differences in pre-Hoffer and post-Hoffer Mallet scale scores are as follows: active abduction, 1.20; external rotation, 1.35; hand-to-neck, 1.25; hand-to-back, 0.75; hand-to-mouth, 0.65; and aggregate score, 5.20 (p<0.001 for all). Average differences in relevant pre-Hoffer and post-Hoffer Active Movement Scale scores are as follows: shoulder abduction, 2.10; shoulder external rotation, 4.25; and shoulder internal rotation, -0.80. All patients maintained full range of motion passively; thus, no functional loss was experienced. These results showed very high statistical significance (p<0.001 for all) and clinical significance. Younger patients (≤6 years) and those with better preoperative shoulder flexion and shoulder internal rotation yielded better postoperative results. The Hoffer procedure provides clinically and statistically significant improvement in external rotation and abduction while preserving functional internal rotation range in the child with obstetrical brachial plexus palsy and secondary shoulder deformity.

The purpose of this study was to report a new surgical technique for the treatment of unstable distal clavicle fracture with modified tension band fixation (MTBF) and coracoclavicular (CC) stabilisation, and evaluate the radiologic and clinical outcome of these patients. Thirteen patients who had a fracture of the distal clavicle (Neer classification type IIb) were treated with MTBF and CC stabilisation. After the CC stabilisation was performed with a suture anchor or flip button, internal fixation using MTBF was carried out. Each patient was followed up for a minimum of 12 months and their clinical and radiological results were analysed. The mean period required for fracture union was 12.6 (range, 8-24) weeks and union was successfully completed in all cases. The mean Constant score at the final follow-up was 94.7 (88-100); the modified University of California, Los Angeles (UCLA) shoulder rating scale was 31.3 points (range, 22-35). All patients returned to normal daily activities at an average of 3.7 months postoperatively (range, 3-5 months). One patient had a new fracture around drilled holes for CC stabilisation by inappropriate tunnelling. MTBF and CC stabilisation is a useful technique for treating an unstable distal clavicle fracture. This procedure provides minimal incision and stable fixation without causing any further acromioclavicular joint injury to those with distal clavicle fractures. Copyright © 2014 Elsevier Ltd.

'Internet addiction' is excessive computer use that interferes with daily life of a person. We designed this study in order to evaluate the predictor effect of depression, loneliness, anger and interpersonal relationship styles for internet addiction as well as develop a model. Forty (40) male internet addicted patients were selected from our hospital's internet Addiction Outpatient Clinic. During the study, the Internet Addiction Test (IAT), the Beck Depression Inventory (BDI), the State Trait Anger Expression Scale (STAXI), the UCLA-Loneliness Scale (UCLA-LS), and the Interpersonal Relationship Styles Scale (IRSS) were used for the evaluation of the patients. The results of this study showed that the 'duration of internet use' (B=2.353, p=0.01) and STAXI 'anger in' subscale (B=1.487, p=0.01) were the predictors of internet addiction. When the clinicians suspect for the internet overuse, regulation of internet usage might be helpful. Psychiatric treatments for expressing anger and therapies that focus on validation of the feelings may be useful.

Evaluative measurement properties of the patient-specific functional scale for primary shoulder complaints in physical therapy practice.

Clinical measurement, longitudinal. To assess the test-retest reliability, construct validity, and responsiveness of the Patient-Specific Functional Scale (PSFS) in patients with a primary shoulder complaint. Health measurement outcomes have become increasingly important for evaluating treatment. Patient-specific questionnaires are useful tools for determining treatment goals and evaluating treatment in individual patients. These questionnaires have not yet been validated in patients with nonspecific shoulder pain. Patients completed the PSFS, the numeric pain rating scale, and the Shoulder Pain and Disability Index at baseline, and after 1 week and 4 to 6 weeks. Test-retest reliability was determined using intraclass correlation coefficients. To assess convergent validity, change scores of the PSFS were correlated with the numeric pain rating scale and Shoulder Pain and Disability Index change scores. Responsiveness was assessed by calculating the area under the curve, the minimal clinically important change, and minimal detectable change, using the global rating of change as an external criterion. Fifty patients (37 men; mean age, 47.7 years) participated in the study. Reliability was high (intraclass correlation coefficient = 0.87; 95% confidence interval [CI]: 0.72, 0.94). The correlations between the change scores of the PSFS and those of the Shoulder Pain and Disability Index and numeric pain rating scale were 0.45 (95% CI: 0.17, 0.80) and 0.55 (95% CI: 0.29, 0.73), respectively. The area under the curve for the PSFS was 0.67 (95% CI: 0.51, 0.83). The minimal detectable change and minimal clinically important change were 0.97 and 1.29 points, respectively. These results suggest that the PSFS is a reliable, valid, and responsive instrument that can be used as an evaluative instrument in patients with a primary shoulder complaint.

Health-related profile and quality of life among nursing home residents: does pain matter?

2013-12-01

The purpose of this exploratory cross-sectional study was to explore the health-related profile and quality of life among older persons living with and without pain in nursing homes. Ten nursing homes were approached, and 535 older persons were invited to join the study from 2009 to 2011. The nursing home residents' demographic information and information regarding their pain situation and the use of oral analgesic drug and nondrug therapy among the older residents with chronic pain were also collected. Residents' physical health (using the Barthel Activities of Daily Living (ADL) and Elderly Mobility Scores); psychologic health, including happiness, life satisfaction, depression, and loneliness (using the Happiness Scale, the Life Satisfaction Scale, the Geriatric Depression Scale, and the UCLA Loneliness Scale); and quality of life were investigated. Among the 535 nursing home residents, 396 (74%) of them suffered from pain, with mean pain scores of 4.09 ± 2.19, indicating medium pain intensity a remaining 139 (26%) reported no pain. The location of pain was mainly in the knees, back and shoulders. Our results demonstrated that, with the exception of the no-pain group (p < .05), nursing home residents' pain affected both their psychologic health, including happiness, life satisfaction, and depression, and their physical quality of life. Nevertheless, only one-half of the older persons with pain used oral analgesic drug or nondrug therapy to relieve their pain. Pain had a significant impact on their mobility and ADL, was positively correlated with happiness and life satisfaction, and was negatively correlated with loneliness and depression. Pain management is a high priority in elderly care; as such, innovative and interdisciplinary strategies are necessary to enhance quality of life particularly for older persons living in nursing homes.

Studies assessing life satisfaction and feelings of loneliness in mid-aged women are scarce. To assess loneliness, life satisfaction and related factors in mid-aged Spanish women. This was a cross sectional study in which 182 women aged 40 to 65 completed the menopause rating scale (MRS), the University of California at Los Angeles loneliness scale (UCLA-LS), the life satisfaction index A (LSI-A), and a general socio-demographic questionnaire containing personal/partner data. Internal consistency of each tool was also computed. Median [interquartile range] age of the sample was 51 [9.0] years. A 55.5% were postmenopausal, 47.3% had increased body mass index (BMI) values, 57.7% were abdominally obese, 1.6% had hypertension and 86.3% had a stable partner. In addition, 4.9% used hormone therapy and 19.2% psychotropic drugs. Multiple linear regression analysis found that higher UCLA-LS scores (more loneliness) correlated with MRS psychological scores, partner alcohol abuse, living in urban areas, lower LSI-A scores (less life satisfaction) and not having a stable partner. Lower LSI-A scores (worse life satisfaction) correlated with severe female economical problems, BMI values and UCLA-LS and MRS psychological scores. Loneliness and life satisfaction in this mid-aged female sample was influenced by personal and partner issues which seem to play a much more relevant role than biological aspects. More research is warranted in this regard. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

To develop and validate a sports activity scale for patients with a diagnosis of femoroacetabular impingement (FAI).
 A nine level Hip Sports Activity Scale (HSAS) was constructed both in German and English languages. Fifty-nine consecutive patients undergoing surgical treatment for FAI at two centers in Switzerland and in the US completed a questionnaire set consisting of the HSAS, the University of California at Los Angeles (UCLA) activity scale and different hip joint-specific and generic outcome tools. For reliability assessment, the HSAS was completed twice about nine days apart. Evidence of reliability, validity and responsiveness was investigated by classical psychometric analyses.
 Reliability was excellent for both the German and the English versions with intraclass correlation coefficients of 0.94 and 0.96, respectively. Evidence of convergent validity was supported by moderate to high correlations with the UCLA activity scale and with the joint-specific measures used. Evidence of divergent validity was supported by low correlations with the SF-12 Mental Component Scale and the WOMAC stiffness subscale. The standardised response mean was 0.69.
 The HSAS is a reliable and valid tool to determine sports levels in patients suffering from FAI. Its use in future studies investigating outcomes in young patients with hip disease can be recommended.

2015-11-01

The aim of this study was to compare the clinical and radiographic outcomes between two different plating methods (superior vs. anteroinferior) in minimally invasive plate osteosynthesis (MIPO) for acute displaced clavicular shaft fractures. A prospective, randomized controlled trial was performed in a single centre. Nineteen patients were treated with superior plating and 18 with anteroinferior plating using the MIPO technique. A 3.5-mm locking reconstruction plate was bent preoperatively and applied to either the anteroinferior or superior aspect of the clavicle through two separate incisions. The operating time, time to union, the proportional length difference, complications, and functional outcome of the shoulder joint were evaluated using the Constant score and the University of California Los Angeles (UCLA) score. There was no statistically significant difference in the Constant score and UCLA score. The mean time to union was 16.8 weeks for superior plating and 17.1 weeks for anteroinferior plating (p=0.866). The average operation time was 77.2min in superior plating and 79.4min in anteroinferior plating (p=0.491). One patient in the superior plating group showed plate failure. Despite no significant difference, one patient had nonunion in the superior plating group (p>0.999). From a clinical perspective, although MIPO with anteroinferior plating provides better outcomes especially in complications without statistically significant difference, both plating methods provided satisfactory clinical and radiographic outcomes.

2006-07-01

The purposes of this study were to assess the loneliness of Japanese high school students who own and use a mobile phone, to clarify the relationships between students' loneliness and their social network and frequency of use of e-mail feature, and to demonstrate relationships with a student's social network and recognition of the benefits and drawbacks of mobile phone use. The participants were 227 students from two classes in each grade of a high school in the Kanto region of Japan. Participants answered a questionnaire covering the UCLA Loneliness Scale as well as questions pertaining to the circumstances of use of their mobile phones, their social networks (e.g., number of friends), and their perceptions of the benefits and drawbacks of mobile phone use. The questionnaires of students owning a mobile phone were analyzed. Total scores for the UCLA Loneliness Scale were calculated, and factor analysis was performed for the benefits and drawbacks. A total of 220 questionnaires were returned, for which 94.1 percent of respondents owned a mobile phone. The percentages of male and female respondents were 58% and 42%. Chronbach's alpha for the UCLA Loneliness Scale (total score) was 0.87, a result similar to previous studies with high school and university students. Factor analysis revealed five factors associated with the benefits and drawbacks of mobile phone use. Multiple-regression analysis showed that 42.9% of the variance in "frequency of e-mail use" was explained by grade level, frequency of mobile phone use, and two of the five factors from the benefits and drawbacks ("difficulty of communication," and "possible sleep loss due to nighttime e-mailing"). Stepwise multiple-regression analysis revealed that 24.4% of the variance in UCLA Loneliness Score was explained by gender, the frequency of e-mail use, the number of friends and the presence/absence of a girlfriend or boyfriend. Presence of an active social network and frequent e-mailing by mobile phone reduced students' loneliness. The frequency depended on their recognition of the benefits and drawbacks of mobile phone use and by the frequency of mobile phone use. This study established that students appreciate the usefulness of their mobile phone as an immediate communication tool, and are aware of its limitations. Although they experience frustration and lack of sleep (because of nighttime use), students use mobile phones to deepen their friendships.

Reliability, validity, and responsiveness of the Persian version of Shoulder Activity Scale in a group of patients with shoulder disorders.

2015-01-01

The aim of this methodological study was to cross-culturally translate the Shoulder Activity Scale (SAS) into the Persian and determine its clinimetric properties including reliability, validity, and responsiveness in patients with shoulder disorders. Persian version of the SAS was obtained after standard forward-backward translation. Three questionnaires were completed by the respondents: SAS, shoulder pain and disability index (SPADI), and Short-Form 36 Health Survey (SF-36). The patients completed the SAS, 1 week after the first visit to evaluate the test-retest reliability. Construct validity was evaluated by examining the associations between the scores on the SAS and the scores obtained from the SPADI, SF-36, and age of the patients. To assess responsiveness, data were collected in the first visit and then again after 4 weeks physiotherapy intervention. Test-retest reliability and internal consistency were assessed using Intra-class Correlation Coefficient (ICC) and Cronbach's alpha, respectively. To evaluate construct validity, Spearman's rank correlation was used. The ability of the SAS to detect changes was evaluated by the receiver-operating characteristics method. No problem or language difficulties were reported during translation process. Test-retest reliability of the SAS was excellent with an ICC of 0.98. Also, the marginal Cronbach's alpha level of 0.64 was obtained. The correlation between the SAS and the SPADI was low, proving divergent validity, whereas the correlations between the SAS and the SF-36/age were moderate proving convergent validity. A marginally acceptable responsiveness was achieved for the Persian SAS. The study provides some evidences to support the test-retest reliability, internal consistency, construct validity, and responsiveness of the Persian version of the SAS in patients with shoulder disorders. Therefore, it seems that this instrument is a useful measure of shoulder activity level in research setting and clinical practice. The shoulder activity scale (SAS) is a reliable, valid, and responsive measure of shoulder activity level in Persian-speaking patients with different shoulder disorders. The results on clinimetric properties of the Persian SAS are comparable with its original, English version. Persian version of the SAS can be used in "clinical" and "research" settings of patients with shoulder disorders.

This retrospective study compared the clinical and radiologic outcomes of patients who underwent arthroscopic rotator cuff repairs by the suture-bridge and double-row modified Mason-Allen techniques. From January 2012 to May 2013, 76 consecutive cases of full-thickness rotator cuff tear, 1 to 4 cm in the sagittal plane, for which arthroscopic rotator cuff repair was performed, were included. The suture-bridge technique was used in 37 consecutive shoulders; and the double-row modified Mason-Allen technique, in 39 consecutive shoulders. Clinical outcomes at a minimum of 2 years (mean, 35.7 months) were evaluated postoperatively using the visual analog scale; University of California, Los Angeles Shoulder Scale; American Shoulder and Elbow Surgeons Subjective Shoulder Scale; and Constant score. Postoperative cuff integrity was evaluated at a mean of 17.7 months by magnetic resonance imaging. At the final follow-up, the clinical outcomes improved in both groups (all P < .001) but with no significant differences between the 2 groups (all P > .05). The retear rate was 18.9% in the shoulders subjected to suture-bridge repair and 12.8% in the double-row modified Mason-Allen group; the difference was not significant (P = .361). Despite the presence of fewer suture anchors, the patients who underwent double-row modified Mason-Allen repair had comparable shoulder functional outcomes and a comparable retear rate with those who underwent suture-bridge repair. Therefore, the double-row modified Mason-Allen repair technique can be considered an effective treatment for patients with medium- to large-sized full-thickness rotator cuff tears.

Prevalence and anatomical location of muscle tenderness in adults with nonspecific neck/shoulder pain

PubMed Central

2011-01-01

Background Many adults experience bothersome neck/shoulder pain. While research and treatment strategies often focus on the upper trapezius, other neck/shoulder muscles may be affected as well. The aim of the present study is to evaluate the prevalence and anatomical location of muscle tenderness in adults with nonspecific neck/shoulder pain. Methods Clinical neck/shoulder examination at two large office workplaces in Copenhagen, Denmark. 174 women and 24 men (aged 25-65 years) with nonspecific neck/shoulder pain for a duration of at least 30 days during the previous year and a pain intensity of at least 2 on a modified VAS-scale of 0-10 participated. Exclusion criteria were traumatic injuries or other serious chronic disease. Using a standardized finger pressure of 2 kg, palpable tenderness were performed of eight anatomical neck/shoulder locations in the left and right side on a scale of 'no tenderness', 'some tenderness' and 'severe tenderness'. Results In women, the levator scapulae, neck extensors and infraspinatus showed the highest prevalence of severe tenderness (18-30%). In comparison, the prevalence of severe tenderness in the upper trapezius, occipital border and supraspinatus was 13-19%. Severe tenderness of the medial deltoid was least prevalent (0-1%). In men, the prevalence of severe tenderness in the levator scapulae was 13-21%, and ranged between 0-8% in the remainder of the examined anatomical locations. Conclusions A high prevalence of tenderness exists in several anatomical locations of the neck/shoulder complex among adults with nonspecific neck/shoulder pain. Future research should focus on several neck/shoulder muscles, including the levator scapulae, neck extensors and infraspinatus, and not only the upper trapezius.

The purpose of this study was to investigate clinical and radiologic outcomes of clavicle hook plate fixation for distal-third clavicle fracture (Neer type II) and to compare the clinical and radiologic outcomes and complications between Neer type IIA and type IIB. We retrospectively reviewed 35 patients who underwent open reduction and internal fixation with AO hook locking compression plate (LCP) for distal clavicle fracture, including 13 patients with Neer type IIA and 22 patients with type IIB. Visual analog scale pain score, shoulder scores (subjective shoulder value, University of California-Los Angeles shoulder score, American Shoulder and Elbow Surgeons score), and active range of motion were evaluated to determine clinical outcome. Coracoclavicular distance was measured, and that of the injured side at last follow-up was compared with that of the uninjured side to evaluate radiologic outcomes. AO hook LCP fixation for distal-third clavicle fracture (Neer type II) produced satisfactory radiologic outcomes, including high union rates (100%) and coracoclavicular distance maintenance, as well as satisfactory clinical outcomes, including visual analog scale score for pain, shoulder scores (subjective shoulder value, University of California-Los Angeles shoulder score, American Shoulder and Elbow Surgeons score), and active range of motion. There were no significant differences between Neer type IIA and type IIB. With regard to complications, 22.9% of patients experienced shoulder stiffness and 17.1% had subacromial erosion; however, there were no significant differences between the 2 groups. The AO hook LCP is a suitable choice for Neer type IIA and type IIB distal-third clavicle fracture fixation. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

2009-11-01

The aim of this study was to evaluate the initial effects of scapular mobilization (SM) on shoulder range of motion (ROM), scapular upward rotation, pain, and function. Pretest-posttest for 3 groups (SM, sham, and control). A double-blinded, randomized, placebo-controlled trial was conducted to evaluate the initial effect of the SM at a sports physiotherapy clinic. 39 subjects (22 women, 17 men; mean age 54.30 +/- 14.16 y, age range 20-77 y). A visual analog scale, ROM, scapular upward rotation, and function were assessed before and just after SM. SM (n = 13) consisted of the application of superoinferior gliding, rotations, and distraction to the scapula. The sham (n = 13) condition replicated the treatment condition except for the hand positioning. The control group (n = 13) did not undergo any physiotherapy and rehabilitation program. Pain severity was assessed with a visual analog scale. Scapular upward rotation was measured with a baseline digital inclinometer. Constant Shoulder Score (CSS) was used to measure shoulder function. After SM, we found significant improvements for shoulder ROM, scapular upward rotation, and CSS between pretreatment and posttreatment compared with the sham and control groups. In the sham group, shoulder-ROM values increased or decreased for the shoulder and scapular upward rotation was not changed. Pain, ROM, and physical function of the shoulder were not significantly different in the sham group than in controls (P > .05). SM may be a useful manual therapy technique to apply to participants with a painful limitation of the shoulder. SM increases ROM and decreases pain intensity.

This study investigated the correlation between the neck disability index (NDI) and visual analogue scale (VAS), which are indicators of neck pain, shoulder joint range of motion (ROM), and muscle strength in women with a slight forward head posture. This study was carried out on 42 female college students attending Uiduk University in Gyeongju, Korea. The neck pain and disability index for each subject was measured using VAS and NDI, respectively. Two physiotherapists measured the shoulder joint ROM and muscle strengths of the subjects using a goniometer and a dynamometer, respectively. External rotation, internal rotation, and abduction of the shoulder joint were measured for each subject. A significant negative correlation between neck pain and shoulder joint ROM in external rotation and the muscle strength of the shoulder joint in abduction was found in the subjects. In addition, a significant positive correlation was observed between ROM in external rotation and muscle strength in abduction. This study showed a significant negative correlation between neck pain and ROM in external rotation as well as between neck pain and the muscle strength in abduction.

Because pangolins are unique mammals with a body and limbs almost entirely sheathed in hard keratinous overlapping scales and with digging and climbing abilities, the shoulder girdle muscles may differ significantly from those of other mammals including the partially osteoderm-clad armadillos. Therefore, we conducted a functional anatomical study of the shoulder girdle muscles in Chinese pangolins (Manis pentadactyla pentadactyla, Pholidota) and some armadillo species (Dasypodidae). Our CT scans revealed that the pangolin's overlapping scales are hard structures completely encasing the limbs. The armadillo's limbs, however, are covered with small relatively soft non-overlapping scales embedded in the skin, and articulate completely free of the hard osteodermal carapace. The attachments of some shoulder girdle muscles in the pangolin have moved from the surrounding edges of the scapula to the spine, and they, therefore, fully cover the scapula. In addition, some pangolin shoulder girdle muscles cross the shoulder joint to insert on the distal humerus, but this does not occur in armadillos. We cannot rule out the possibility that these muscle modifications represent adaptations for digging and/or climbing in pangolins. Our results and previous literature do not establish specific links between them and locomotive modes. However, we propose that the Chinese pangolin may use its derived muscular features when walking to move its armor-restricted forelimbs more effectively by swinging its head from side to side. © 2015 Wiley Periodicals, Inc.

Objective To assess whether functional activity, perceived health, and depressive symptoms differ between individuals with traumatic paraplegia with and without shoulder pain. Design Cross sectional and comparative investigation using the unified questionnaire. Setting Neural Regeneration and Repair Division unit of Taipei Veterans General Hospital in Taiwan. Participants Seventy-six patients with paraplegia (23 with and 53 without shoulder pain) who had experienced spinal cord injury at American Spinal Injury Association Impairment Scale T2 to T12 neurologic level (at least 6 months previously). Outcome measures Spinal Cord Independence Measure (SCIM), a single item from the Medical Outcomes Study 36-Item Short-Form Health Survey, and Patient Health Questionnaire-9 (PHQ-9) depression scale. Results Shoulder pain was prevalent in 30% patients. Patients with shoulder pain had significantly worse perceived health and greater depressive symptoms than those without. No significant difference was found in functional ability between groups. Greater shoulder pain intensity was related to higher depressive scores (r = 0.278, P = 0.017) and lower self-perceived health scores (r = −0.433, P < 0.001) but not SCIM scores (P = 0.342). Conclusion Although shoulder pain was unrelated to functional limitation, it was associated with lower perceived health and higher depressive mood levels. PMID:25296991

The aim of the current study was to investigate the relationship between pressure pain thresholds, shoulder movement, mood state, pain perception, muscle endurance, quality of life and fatigue in breast cancer survivors (BCS). Fifty-nine BCS reporting fatigue were examined at 6 months post-treatment. Women completed the Piper Fatigue Scale, the Breast Cancer-Specific Quality of Life Questionnaire, the Profile of Mood State, and neck-shoulder visual analogue scale. Additionally, shoulder flexion range of motion, the McQuade test (trunk flexor endurance) and pressure pain thresholds over the C5-C6 joint, the deltoid muscle, the second metacarpal and tibialis anterior muscle were assessed. Fatigue was greater in those patients with higher depression (r= 0.45, P < 0.05), higher shoulder pain (r= 0.39, P < 0.05), higher neck pain (r= 0.46, P < 0.01), lower body image (r=-0.34, P < 0.05) and reduced shoulder movement (r=-0.32, P < 0.05). Regression analyses demonstrated that depression, cervical pain intensity, body image and shoulder mobility were associated with fatigue (r= 0.55, P < 0.001). A psychological state characterised with higher depression and reduced body image and a physical impairment with higher cervical pain intensity and reduced shoulder mobility confirm multidimensional character of fatigue in BCS. © 2011 Blackwell Publishing Ltd.

Background: Glenohumeral instability is a common abnormality, especially among athletes. Previous studies have evaluated outcomes after arthroscopic stabilization in patients with anterior or posterior shoulder instability but have not compared outcomes between groups. Purpose: To compare return-to-sport and other patient-reported outcomes in patients after primary arthroscopic anterior, posterior, and combined anterior and posterior shoulder stabilization. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary arthroscopic anterior, posterior, or combined anterior and posterior shoulder stabilization were contacted at a minimum 2-year follow-up. Patients completed a survey that consisted of return-to-sport outcomes as well as the Western Ontario Shoulder Instability Index (WOSI), Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Sur’geons (ASES) score, and Shoulder Activity Scale. Results: A total of 151 patients were successfully contacted (anterior: n = 81; posterior: n = 22; combined: n = 48) at a mean follow-up of 3.6 years. No significant differences were found between the groups with regard to age at the time of surgery or time to follow-up. No significant differences were found between the groups in terms of WOSI (anterior: 76; posterior: 70; combined: 78; P = .28), SANE (anterior: 87; posterior: 85; combined: 87; P = .79), ASES (anterior: 88; posterior: 83; combined: 91; P = .083), or Shoulder Activity Scale (anterior: 12.0; posterior: 12.5; combined: 12.5; P = .74) scores. No significant difference was found between the groups in terms of the rate of return to sport (anterior: 73%; posterior: 68%; combined: 75%; P = .84). Conclusion: Athletes undergoing arthroscopic stabilization of anterior, posterior, or combined shoulder instability can be expected to share a similar prognosis. High patient-reported outcome scores and moderate to high rates of return to sport were achieved by all groups. PMID:29637085

To determine whether there is a difference in shoulder-related physical function and quality of life between postoperative rehabilitation patients receiving standard care and those receiving care according to the American Society of Shoulder and Elbow Therapists' rehabilitation guideline for arthroscopic anterior capsulolabral repair of the shoulder. Descriptive studies with comparison between a retrospective and a prospective cohort. Municipal outpatient rehabilitation centre. A total of 96 arthroscopic Bankart-operated patients. A total of 52 patients received standard care; 44 patients underwent rehabilitation according to the American Society of Shoulder and Elbow Therapists' rehabilitation guideline. Primary outcome variable was Western Ontario Shoulder Instability Index. Secondary outcome measures were Patient-Specific Functional Scale, shoulder range of motion, return to work, return to sports, and costs. There was no significant difference in adjusted mean change scores between the standard care group and the guideline group in the primary outcome variable (Western Ontario Shoulder Instability Index total = 574.85 vs. 644.48) or the secondary outcomes (Patient-Specific Functional Scale = 4.6 vs. 5.0; range of motion in forward flexion = 46.49° vs. 49.58°; external rotation in adduction = 28.58° vs. 34.18°; external rotation in abduction = 51.29° vs. 47.55°; weeks until return to work = 5.2 vs. 6.9; weeks until return to sports =13.9 vs. 13.1; costs = number of visits; 18.5 vs. 15.9). There were no significant between-group differences in shoulder-related physical function and quality of life between the standard care group and the guideline group, following Bankart operations. © The Author(s) 2014.

To estimate the impact of a U.S. inner-city medical education program on medical school graduates' intentions to practice in underserved communities. The authors conducted an analysis of secondary data on 1,088 medical students who graduated from either the joint University of California, Los Angeles/Charles R. Drew University Medical Education Program (UCLA/Drew) or the UCLA School of Medicine between 1996 and 2002. Intention to practice in underserved communities was measured using students' responses to questionnaires administered at matriculation and graduation for program improvement by the Association of American Medical Colleges. Multivariate logistic regression analysis was used to compare the odds of intending to practice in underserved communities among UCLA/Drew students with those of their counterparts in the UCLA School of Medicine. Compared with students in the UCLA School of Medicine, UCLA/Drew students had greater adjusted odds of reporting intention to work in underserved communities at graduation, greater odds of maintaining or increasing such intentions between matriculation and graduation, and lower odds of decreased intention to work in underserved communities between matriculation and graduation. Training in the UCLA/Drew program was independently associated with intention to practice medicine in underserved communities, suggesting that a medical education program can have a positive effect on students' goals to practice in underserved areas.

Frozen shoulder is a glenohumeral joint disorder that movement because of adhesion and the existence of fibrosis in the shoulder capsule. Platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. To date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. A 45-year-old man with shoulder adhesive capsulitis volunteered for this treatment. He underwent two consecutive platelet-rich plasma injections at the seventh and eighth month after initiation of symptoms. We measured pain, function, ROM by the visual analogue scale (VAS), scores from the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and goniometer; respectively. After first injection, the patient reported 60% improvement regarding diurnal shoulder pain, and no night pain. Also, two-fold improvement for ROM and more than 70% improvement for function were reported. This study suggests the use of platelet-rich plasma in frozen shoulder to be tested in randomized trials.

The arthroscopic suture-bridge technique has proved to provide biomechanically firm fixation of the torn rotator cuff to the tuberosity by increasing the footprint contact area and pressure. However, a marginal dog-ear deformity is encountered not infrequently when this technique is used, impeding full restoration of the torn cuff. To evaluate the structural and functional outcomes of the use of a modified suture-bridge technique to prevent a marginal dog-ear deformity compared with a conventional suture-bridge method in rotator cuff repair. Cohort study; Level of evidence 2. A consecutive series of 71 patients aged 50 to 65 years who underwent arthroscopic rotator cuff repair for full-thickness medium-sized to massive tears was evaluated. Patients were divided into 2 groups according to repair technique: a conventional suture-bridge technique (34 patients; group A) versus a modified suture-bridge technique to prevent a marginal dog-ear deformity (37 patients; group B). Radiographic evaluations included postoperative cuff integrity using MRI. Functional evaluations included pre- and postoperative range of motion (ROM), pain visual analog scale (VAS), the University of California, Los Angeles (UCLA) shoulder rating scale, the Constant score, and the American Shoulder and Elbow Surgeons (ASES) score. All patients were followed up clinically at a minimum of 1 year. When the 2 surgical techniques were compared, postoperative structural integrity by Sugaya classification showed the distribution of types I:II:III:IV:V to be 4:20:2:4:4 in group A and 20:12:4:0:1 in group B. More subjects in group B had a favorable Sugaya type compared with group A (P < .001). The postoperative healed:retear rate was 26:8 in group A and 36:1 in group B, with a significantly lower retear rate in group B (P = .011). However, there were no significant differences in ROM and all functional outcome scores between the 2 groups postoperatively. When surgical techniques were compared across healed (n = 62) and retear (n = 9) groups, significantly fewer modified suture-bridge technique repairs were found in the retear group (P = .03). There were significant differences between healed and retear groups in functional outcome scores, with worse results in the retear group. A modified suture-bridge technique to prevent a marginal dog-ear deformity provided better structural outcomes than a conventional suture-bridge technique for medium-sized to massive rotator cuff tears. This technique may ultimately provide better functional outcomes by decreasing the retear rate. © 2014 The Author(s).

Fall prevention is essential in patients after arthroscopic rotator cuff repair because of the high risk of re-rupture. However, there are no reports related to falls that occur during the early postoperative period, while the affected limb is immobilized. This study assessed gait performance and falls in patients using a shoulder abduction brace after arthroscopic rotator cuff repair. Prospective cohort and postoperative repeated measures. This study included 29 patients (mean age, 67.1 ± 7.4 years) who underwent arthroscopic rotator cuff repair followed by rehabilitation. The timed up and go test, Geriatric Depression Scale, and Falls Efficacy Scale were measured, and the numbers of falls were compared between those shoulder abduction brace users and patients who had undergone total hip or knee arthroplasty. In arthroscopic rotator cuff repair patients, there were significant improvements in timed up and go test and Geriatric Depression Scale, but no significant differences in Falls Efficacy Scale, between the second and fifth postoperative weeks ( p < 0.05). Additionally, arthroscopic rotator cuff repair patients fell more often than patients with total hip arthroplasty or total knee arthroplasty during the same period. The findings suggest that rehabilitation in arthroscopic rotator cuff repair patients is beneficial, but decreased gait performance due to the immobilizing shoulder abduction brace can lead to falls. Clinical relevance Although rehabilitation helps motor function and mental health after arthroscopic rotator cuff repair, shoulder abduction brace use is associated with impaired gait performance, high Falls Efficacy Scale scores, and risk of falls, so awareness of risk factors including medications and lower limb dysfunctions is especially important after arthroscopic rotator cuff repair.

UCLA IGPP Space Plasma Simulation Group

NASA Technical Reports Server (NTRS)

1998-01-01

During the past 10 years the UCLA IGPP Space Plasma Simulation Group has pursued its theoretical effort to develop a Mission Oriented Theory (MOT) for the International Solar Terrestrial Physics (ISTP) program. This effort has been based on a combination of approaches: analytical theory, large scale kinetic (LSK) calculations, global magnetohydrodynamic (MHD) simulations and self-consistent plasma kinetic (SCK) simulations. These models have been used to formulate a global interpretation of local measurements made by the ISTP spacecraft. The regions of applications of the MOT cover most of the magnetosphere: the solar wind, the low- and high-latitude magnetospheric boundary, the near-Earth and distant magnetotail, and the auroral region. Most recent investigations include: plasma processes in the electron foreshock, response of the magnetospheric cusp, particle entry in the magnetosphere, sources of observed distribution functions in the magnetotail, transport of oxygen ions, self-consistent evolution of the magnetotail, substorm studies, effects of explosive reconnection, and auroral acceleration simulations.

The aim of the current study was to validate the self-report section of the American Shoulder and Elbow Surgeons questionnaire (ASES-p) into Spanish. Shoulder pathology patients were recruited and followed up to 6 months post treatment. The ASES-p, Constant, SF-36 and Barthel scales were filled-in pre and post treatment. Reliability was tested with Cronbach's alpha, convergent validity with Spearman's correlations coefficients. Confirmatory factor analysis (CFA) and the Rasch model were implemented for assessing structural validity and unidimensionality of the scale. Models with and without the pain item were considered. Responsiveness to change was explored via standardised effect sizes. Results were acceptable for both tested models. Cronbach's alpha was 0.91, total scale correlations with Constant and physical SF-36 dimensions were >0.50. Factor loadings for CFA were >0.40. The Rasch model confirmed unidimensionality of the scale, even though item 10 "do usual sport" was suggested as non-informative. Finally, patients with improved post treatment shoulder function and those receiving surgery had higher standardised effect sizes. The adapted Spanish ASES-p version is a valid and reliable tool for shoulder evaluation and its unidimensionality is supported by the data.

Platelet-rich plasma (PRP) has been recently used to enhance and accelerate the healing of musculoskeletal injuries and diseases, but evidence is still lacking, especially on its effects after rotator cuff repair. Platelet-rich plasma accelerates recovery after arthroscopic rotator cuff repair in pain relief, functional outcome, overall satisfaction, and enhanced structural integrity of repaired tendon. Cohort study; Level of evidence, 2. Forty-two patients with full-thickness rotator cuff tears were included. Patients were informed about the use of PRP before surgery and decided themselves whether to have PRP placed at the time of surgery. Nineteen patients underwent arthroscopic rotator cuff repair with PRP and 23 without. Platelet-rich plasma was prepared via plateletpheresis and applied in the form of a gel threaded to a suture and placed at the interface between tendon and bone. Outcomes were assessed preoperatively and at 3, 6, 12, and finally at a minimum of 16 months after surgery (at an average of 19.7 ± 1.9 months) with respect to pain, range of motion, strength, and overall satisfaction, and with respect to functional scores as determined using the following scoring systems: the American Shoulder and Elbow Surgeon (ASES) system, the Constant system, the University of California at Los Angeles (UCLA) system, the Disabilities of the Arm, Shoulder and Hand (DASH) system, the Simple Shoulder Test (SST) system, and the Shoulder Pain and Disability Index (SPADI) system. At a minimum of 9 months after surgery, repaired tendon structural integrities were assessed by magnetic resonance imaging. Platelet-rich plasma gel application to arthroscopic rotator cuff repairs did not accelerate recovery with respect to pain, range of motion, strength, functional scores, or overall satisfaction as compared with conventional repair at any time point. Whereas magnetic resonance imaging demonstrated a retear rate of 26.7% in the PRP group and 41.2% in the conventional group, there was no statistical significance between the groups (P = .388). The results suggest that PRP application during arthroscopic rotator cuff repair did not clearly demonstrate accelerated recovery clinically or anatomically except for an improvement in internal rotation. Nevertheless, as the study may have been underpowered to detect clinically important differences in the structural integrity, additional investigations, including the optimization of PRP preparation and a larger randomized study powered for healing rate, are necessary to further determine the effect of PRP.

This study seeks to investigate the psychometric properties of the short version of the revised 'Experience of Close Relationships' questionnaire, comparing non-clinical and clinical samples. In total 702 subjects participated in this study, of whom 531 were non-clinical participants and 171 were psychiatric patients. They completed the short version of the revised 'Experience of Close Relationships' questionnaire (ECR-R-18), the Perceived Stress Scale-10(PSS-10), the Rosenberg Self-Esteem Scale (RSES) and the UCLA Loneliness scale. A retest of the ECR-R-18 was then performed at four-week intervals. Then, confirmatory factor analyses were performed to test the validity of the new scale. The ECR-R-18 showed a fair to good internal consistency (α 0.77 to 0.87) for both samples, and the test-retest reliability was found to be satisfactory (ICC = 0.75). The anxiety sub-scale demonstrated concurrent validity with PSS-10 and RSES, while the avoidance sub-scale showed concurrent validity with the UCLA Loneliness Scale. Confirmatory factor analysis using method factors yielded two factors with an acceptable model fit for both groups. An invariance test revealed that the ECR-R-18 when used on the clinical group differed from when used with the non-clinical group. The ECR-R-18 questionnaire revealed an overall better level of fit than the original 36 item questionnaire, indicating its suitability for use with a broader group of samples, including clinical samples. The reliability of the ECR-R- 18 might be increased if a modified scoring system is used and if our suggestions with regard to future studies are followed up.

The reverse shoulder prosthesis aims to restore the stability and function of pathological shoulders, but the biomechanical aspects of the geometrical changes induced by the implant are yet to be fully understood. Considering a large-scale musculoskeletal model of the upper limb, the aim of this study is to evaluate how the Delta reverse shoulder prosthesis influences the biomechanical behavior of the shoulder joint. In this study, the kinematic data of an unloaded abduction in the frontal plane and an unloaded forward flexion in the sagittal plane were experimentally acquired through video-imaging for a control group, composed of 10 healthy shoulders, and a reverse shoulder group, composed of 3 reverse shoulders. Synchronously, the EMG data of 7 superficial muscles were also collected. The muscle force sharing problem was solved through the minimization of the metabolic energy consumption. The evaluation of the shoulder kinematics shows an increase in the lateral rotation of the scapula in the reverse shoulder group, and an increase in the contribution of the scapulothoracic joint to the shoulder joint. Regarding the muscle force sharing problem, the musculoskeletal model estimates an increased activity of the deltoid, teres minor, clavicular fibers of the pectoralis major, and coracobrachialis muscles in the reverse shoulder group. The comparison between the muscle forces predicted and the EMG data acquired revealed a good correlation, which provides further confidence in the model. Overall, the shoulder joint reaction force was lower in the reverse shoulder group than in the control group. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study is to evaluate the stability of interface between Co-Cr-Mo (CCM) UCLA abutment and external hex implant. Sixteen external hex implant fixtures were assigned to two groups (CCM and Gold group) and were embedded in molds using clear acrylic resin. Screw-retained prostheses were constructed using CCM UCLA abutment and Gold UCLA abutment. The external implant fixture and screw-retained prostheses were connected using abutment screws. After the abutments were tightened to 30 Ncm torque, 5 kg thermocyclic functional loading was applied by chewing simulator. A target of 1.0 × 10 6 cycles was applied. After cyclic loading, removal torque values were recorded using a driving torque tester, and the interface between implant fixture and abutment was evaluated by scanning electronic microscope (SEM). The means and standard deviations (SD) between the CCM and Gold groups were analyzed with independent t-test at the significance level of 0.05. Fractures of crowns, abutments, abutment screws, and fixtures and loosening of abutment screws were not observed after thermocyclic loading. There were no statistically significant differences at the recorded removal torque values between CCM and Gold groups ( P >.05). SEM analysis revealed that remarkable wear patterns were observed at the abutment interface only for Gold UCLA abutments. Those patterns were not observed for other specimens. Within the limit of this study, CCM UCLA abutment has no statistically significant difference in the stability of interface with external hex implant, compared with Gold UCLA abutment.

In the past, several studies have suggested the existence of a "periarthritic personality" in patients with frozen shoulder. We conducted a study to determine differences in personality traits in patients with primary and secondary frozen shoulders. We prospectively evaluated 118 patients (84 women and 34 men; mean age, 53.8 years; SD 7.56) with a frozen shoulder. Of these patients, 48 had an idiopathic frozen shoulder and 70 had a secondary frozen shoulder. Personality traits were determined by the NEO Five-Factor Inventory (NEO-FFI) scale. This questionnaire measures the 5 major personality traits and is based on the norms determined in a neutral test situation for 2415 controls. Compared with healthy controls, no differences in personality traits were found in patients with primary and secondary frozen shoulder, except for Conscientiousness and Extraversion, for which patients with secondary frozen shoulder scored significantly higher than healthy controls. Patients with primary frozen shoulder scored significantly higher on Openness to Experience than did patients with secondary frozen shoulder; on the other 4 Big Five personality traits, no significant differences were found between patients with primary and secondary frozen shoulder. More specifically, patients with idiopathic frozen shoulder did not score higher on the trait Neuroticism as would be expected from previous publications. Our study results do not indicate that patients with an idiopathic frozen shoulder have a specific personality compared with healthy controls. Only a few differences were found in personality traits when the entire frozen shoulder group was compared with healthy controls and between patients with primary and secondary frozen shoulders. The results of this study suggest that these differences are not sufficient to speak about a specific "frozen shoulder personality."

Hikikomori, a form of social withdrawal first reported in Japan, may exist globally but cross-national studies of cases of hikikomori are lacking. To identify individuals with hikikomori in multiple countries and describe features of the condition. Participants were recruited from sites in India, Japan, Korea and the United States. Hikikomori was defined as a 6-month or longer period of spending almost all time at home and avoiding social situations and social relationships, associated with significant distress/impairment. Additional measures included the University of California, Los Angeles (UCLA) Loneliness Scale, Lubben Social Network Scale (LSNS-6), Sheehan Disability Scale (SDS) and modified Cornell Treatment Preferences Index. A total of 36 participants with hikikomori were identified, with cases detected in all four countries. These individuals had high levels of loneliness (UCLA Loneliness Scale M = 55.4, SD = 10.5), limited social networks (LSNS-6 M = 9.7, SD = 5.5) and moderate functional impairment (SDS M = 16.5, SD = 7.9). Of them 28 (78%) desired treatment for their social withdrawal, with a significantly higher preference for psychotherapy over pharmacotherapy, in-person over telepsychiatry treatment and mental health specialists over primary care providers. Across countries, participants with hikikomori had similar generally treatment preferences and psychosocial features. Hikikomori exists cross-nationally and can be assessed with a standardized assessment tool. Individuals with hikikomori have substantial psychosocial impairment and disability, and some may desire treatment. © The Author(s) 2014.

We collected data on breeding season diet composition of Red-shouldered Hawks (Buteo lineatus) in south Texas and compared these data, and those reported from studies elsewhere to examine large scale spatial variation in prey use in eastern North America. Red-shouldered Hawk diets aligned into two significantly different groups, which appear to correlate with latitude. The diets of Red-shouldered Hawks in group 1, which are of more northern latitudes, had significantly more mammalian prey and significantly less amphibian prey than those in group 2, which are at more southerly latitudes. Our meta-analysis demonstrated the dietary flexibility of Red-shouldered Hawks, which likely accounts for their broad distribution by exploiting regional variations in taxon-specific prey availability.

The goals of this study were to compare neck and shoulder stiffness values determined by shear wave ultrasound elastography with those obtained with a muscle hardness meter and to verify the correspondence between objective and subjective stiffness in the neck and shoulder. Twenty-four young men and women participated in the study. Their neck and shoulder stiffness was determined at six sites. Before the start of the measurements, patients rated their present subjective symptoms of neck and shoulder stiffness on a 6-point verbal scale. At all measurement sites, the correlation coefficients between the values of muscle hardness indices determined by the muscle hardness meter and shear wave ultrasound elastography were not significant. Furthermore, individuals' subjective neck and shoulder stiffness did not correspond to their objective symptoms. These results suggest that the use of shear wave ultrasound elastography is essential to more precisely assess neck and shoulder stiffness.

We recently constructed a general population job exposure matrix (JEM), The Shoulder JEM, based on expert ratings. The overall aim of this study was to convert expert-rated job exposures for upper arm elevation and repetitive shoulder movements to measurement scales. The Shoulder JEM covers all Danish occupational titles, divided into 172 job groups. For 36 of these job groups, we obtained technical measurements (inclinometry) of upper arm elevation and repetitive shoulder movements. To validate the expert-rated job exposures against the measured job exposures, we used Spearman rank correlations and the explained variance[Formula: see text] according to linear regression analyses (36 job groups). We used the linear regression equations to convert the expert-rated job exposures for all 172 job groups into predicted measured job exposures. Bland-Altman analyses were used to assess the agreement between the predicted and measured job exposures. The Spearman rank correlations were 0.63 for upper arm elevation and 0.64 for repetitive shoulder movements. The expert-rated job exposures explained 64% and 41% of the variance of the measured job exposures, respectively. The corresponding calibration equations were y=0.5%time+0.16×expert rating and y=27°/s+0.47×expert rating. The mean differences between predicted and measured job exposures were zero due to calibration; the 95% limits of agreement were ±2.9% time for upper arm elevation >90° and ±33°/s for repetitive shoulder movements. The updated Shoulder JEM can be used to present exposure-response relationships on measurement scales. Published by the BMJ Publishing Group Limited.

The arthroscopic Bankart repair and open Bristow-Latarjet procedure are the 2 most commonly used techniques to treat recurrent shoulder instability. To compare in a case control-matched manner the 2 techniques, with particular emphasis on return to sport after surgery. Cohort study; Level of evidence, 3. A study was conducted in 2 hospitals matching 60 patients with posttraumatic recurrent anterior shoulder instability with a minimum follow-up of 2 years (30 patients treated with arthroscopic Bankart procedure and 30 treated with open Bristow-Latarjet procedure). Patients with severe glenoid bone loss and revision surgeries were excluded. In one hospital, patients were treated with arthroscopic Bankart repair using anchors; in the other, patients underwent the Bristow-Latarjet procedure. Patients were matched according to age at surgery, type and level of sport practiced before shoulder instability (Degree of Shoulder Involvement in Sports [DOSIS] scale), and number of dislocations. The primary outcomes were return to sport (Subjective Patient Outcome for Return to Sports [SPORTS] score), rate of recurrent instability, Oxford Shoulder Instability Score (OSIS), Subjective Shoulder Value (SSV), Western Ontario Shoulder Instability Index (WOSI), and range of motion (ROM). After a mean follow-up of 5.3 years (range, 2-9 years), patients who underwent arthroscopic Bankart repair obtained better results in terms of return to sport (SPORTS score: 8 vs 6; P = .02) and ROM in the throwing position (86° vs 79°; P = .01), and they reported better subjective perception of the shoulder (SSV: 86% vs 75%; P = .02). No differences were detectable using the OSIS or WOSI. The rate of recurrent instability was not statistically different between the 2 groups (Bankart repair 10% vs Bristow-Latarjet 0%; P = .25), although the study may have been underpowered to detect a clinically important difference in this parameter. The multiple regression analysis showed that the independent variables associated with return to sport were preoperative DOSIS scale, type of surgery, and recurrent dislocations after surgery. Patients who played sports with high upper extremity involvement (eg, swimming, rugby, martial arts) at a competitive level (DOSIS scale 9 or 10) had a lower level of return to sport with both repair techniques. Arthroscopic stabilization using anchors provided better return to sport and subjective perception of the shoulder compared with the open Bristow-Latarjet procedure in the population studied. Recurrence may be higher in the arthroscopic Bankart group; further study is needed on this point. © 2016 The Author(s).

PURPOSE The purpose of this study is to evaluate the stability of interface between Co-Cr-Mo (CCM) UCLA abutment and external hex implant. MATERIALS AND METHODS Sixteen external hex implant fixtures were assigned to two groups (CCM and Gold group) and were embedded in molds using clear acrylic resin. Screw-retained prostheses were constructed using CCM UCLA abutment and Gold UCLA abutment. The external implant fixture and screw-retained prostheses were connected using abutment screws. After the abutments were tightened to 30 Ncm torque, 5 kg thermocyclic functional loading was applied by chewing simulator. A target of 1.0 × 106 cycles was applied. After cyclic loading, removal torque values were recorded using a driving torque tester, and the interface between implant fixture and abutment was evaluated by scanning electronic microscope (SEM). The means and standard deviations (SD) between the CCM and Gold groups were analyzed with independent t-test at the significance level of 0.05. RESULTS Fractures of crowns, abutments, abutment screws, and fixtures and loosening of abutment screws were not observed after thermocyclic loading. There were no statistically significant differences at the recorded removal torque values between CCM and Gold groups (P>.05). SEM analysis revealed that remarkable wear patterns were observed at the abutment interface only for Gold UCLA abutments. Those patterns were not observed for other specimens. CONCLUSION Within the limit of this study, CCM UCLA abutment has no statistically significant difference in the stability of interface with external hex implant, compared with Gold UCLA abutment.

2018-01-01

Rotator cuff tendinopathy is a primary cause of shoulder pain and dysfunction. Several effective nonsurgical treatment methods have been described for chronic rotator cuff tendinopathy. Prolotherapy with polydeoxyribonucleotide (PDRN), which consists of active deoxyribonucleotide polymers that stimulate tissue repair, is a nonsurgical regenerative injection that may be a viable treatment option. The objective of this study was to assess the efficacy of PDRN in the treatment of chronic rotator cuff tendinopathy. The records of patients with chronic rotator cuff tendinopathy ( n =131) were reviewed retrospectively, and the patients treated with PDRN prolotherapy ( n =32) were selected. We measured the main outcome of the shoulder pain and disability index score on a numerical rating scale of average shoulder pain. Compared with baseline data, significant improvements in the shoulder pain and disability index and pain visual analog scale scores were demonstrated at one week after the end of treatment, and at one month and three months later. PDRN prolotherapy may improve the conservative treatment of painful rotator cuff tendinopathy for a specific subset of patients.

Complication rates remain high after reverse total shoulder arthroplasty (RTSA). Salvage options after implant failure have not been well defined. This study examines the role of reimplantation and revision RTSA after failed RTSA, reporting outcomes and complications of this salvage technique. Sixteen patients underwent component revision and reimplantation after a prior failed RTSA from 2004 to 2011. Indications included baseplate failure (7 patients, 43.8%), instability (6 patients, 37.5%), infection (2 patients, 12.5%), and humeral loosening (1 patient, 6.3%). The average age of the patient during revision surgery was 68.6 years. Outcomes information at follow-up was recorded, including visual analog scale score for pain, subjective shoulder value, American Shoulder and Elbow Surgeons score, and Simple Shoulder Test score, and these were compared with pre-revision values. Repeated surgeries and complications were noted. Average time to follow-up from revision was 58.9 months (minimum, 2 years; range, 24-103 months). The average postoperative visual analog scale score for pain was 1.7/10 (7.5/10 preoperatively; P < .0001), and the subjective shoulder value was 62% (17% preoperatively; P < .0001). The average postoperative American Shoulder and Elbow Surgeons score was 66.7, and the Simple Shoulder Test score was 52.6. Fourteen patients (88%) noted that they felt "better" postoperatively than before their original RTSA and would go through the procedure again if given the option. Nine patients suffered major complications (56%), and 6 of these ultimately underwent further procedures (38% of cohort). Salvage options after failure of RTSA remain limited. Component revision and reimplantation can effectively relieve pain and improve function compared with baseline values, and patient satisfaction levels are moderately high. However, complication rates and reoperation rates are significant. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc. All rights reserved.

2015-09-01

There are little patient-reported data on functional outcomes of tarsal coalition resection in children and adolescents. The purpose of this study is to evaluate the medium-term (>2 y) outcomes in patients who have had surgical excision of their symptomatic tarsal coalition and to compare patient-based outcomes in patients who have calcaneonavicular (CN) coalitions to those with talocalcaneal (TC) coalitions. A billing query was conducted to identify patients who had surgical excision of their tarsal coalition between 2003 and 2008. Eligible patients were mailed questionnaires consisting of a modified American Orthopaedic Foot and Ankle Society (AOFAS) score and the University of California at Los Angeles (UCLA) activity scale. Patients were also specifically asked if their activity level was limited by their foot pain. Only patients who returned questionnaires were included. Demographics and diagnostic images were reviewed. A nonresponder analysis was completed. Complications such as infection and reoperation were reported. Sixty-three patients (22 females, 41 males) who returned questionnaires were included in the analysis. Twenty-four patients had bilateral surgery. TC coalitions were present in 20 patients (32%); CN coalitions were present in 43 patients (68%).Overall, mean modified AOFAS score was 88.3 and mean UCLA activity score was 8.33 at an average of 4.62 years after surgery. Patients who had TC coalitions had similar modified AOFAS scores (88.4) and UCLA activity scores (8.4) when compared with those with CN coalitions (88.0 and 8.3, both not significant).Of the 73% (46/63) patients who reported that their activity levels were not limited by their foot pain, the mean AOFAS score was 93.9 and the mean UCLA activity score was 8.9; 32 of these were CN and 14 were TC coalitions. Of the 27% (17/63) patients who reported that their activity levels were limited by their foot pain, the mean AOFAS score was 72.9 and the mean UCLA activity score was 6.9; 11 of these were CN and 6 were TC coalitions. There was a statistically significant difference in these groups both in modified AOFAS score (P<0.0001) and UCLA activity score (P=0.006). There was no difference in outcomes between those who were treated for a TC and CN coalition. Patient-reported outcomes after surgical excision of tarsal coalition reveal that >70% of patients' activities are not limited by pain and their functional outcome is terrific. A few patients continue to have problems with ongoing foot pain and activity limitations. The type of coalition does not seem to be an indicative factor in determining outcome.

To conduct a meta-analysis with randomized controlled trials (RCTs) published in full text to determine the benefits of concomitant acromioplasty in repairing full-thickness rotator cuff tears. Literature search was performed in PubMed, Embase and the Cochrane Library from databases inception through February 2016 to identify RCTs evaluating the efficacy of performing a concomitant acromioplasty. Statistical heterogeneity among studies was quantitatively evaluated by I-squared index (I(2)) and trial sequential analysis (TSA) was applied to control random errors. Five RCTs totaling 523 patients were included. There was no statistically significant difference in Constant score (WMD = 1.00; 95 % CI -4.40 to 6.41; P = 0.72), University of California-Los Angeles (UCLA) score (WMD = 0.48; 95 % CI -0.79 to 1.76; P = 0.46), visual analog scale (VAS) for pain (WMD = -0.23; 95 % CI -0.58 to 0.11; P = 0.19) and re-tear rate (RR = 0.46; 95 % CI 0.14 to 1.53; P = 0.21) between acromioplasty group and the nonacromioplasty group. However, it was found to be related to a greater increase in American Shoulder and Elbow Surgeons (ASES) score (WMD = 3.02; 95 % CI 0.24 to 5.80; P = 0.03). Unfortunately, this difference was not reinforced by subsequent TSA. In addition, subgroup analysis showed no substantial difference of ASES score in patients with type-1 (WMD = -8.21; 95 % CI -23.55 to 7.14; P = 0.29), type-2 (WMD = 0.97; 95 % CI -5.10 to 7.05; P = 0.75), or type-3 (WMD = 2.32; 95 % CI -9.96 to 14.61; P = 0.71) acromion. A significant higher ASES score was observed during the comparison despite lacking reinforcement by TSA. No difference was found in Constant score, UCLA score, VAS, re-tear rate and subgroup analysis did not confirm the impact of acromion type on eventual therapeutic outcome. Future studies with large number of participants, long-term follow-ups, data of patient-reported outcomes and stratification for acromion type are of the essence for demonstrating whether functional or structural differences exist in patients undergoing arthroscopic repair of full-thickness rotator cuff tears with or without acromioplasty.

Ankle arthrodesis (AAD) and total ankle replacement (TAR) are the major surgical treatment options for severe ankle arthritis. There is an ongoing discussion in the orthopaedic community whether ankle arthrodesis or ankle fusion should be the treatment of choice for end stage osteoarthritis. The purpose of this study was to compare the participation in sports and recreational activities in patients who underwent either AAD or TAR for end-stage osteoarthritis of the ankle. A total of 41 patients (21 ankle arthrodesis /20 TAR) were examined at 34.5 (SD18.0) months after surgery. At follow-up, pre- and postoperative participation in sports and recreational activities has been assessed. Activity levels were determined using the ankle activity score according to Halasi et al. and the University of California at Los Angeles (UCLA) activity scale. Clinical and functional outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. The percentage of patients participating in sports and recreational activities, UCLA score and AOFAS score were compared between both treatment groups. In the AAD group 86% were active in sports preoperatively and in the TAR group this number was 76%. Postoperatively in both groups 76% were active in sports (AAD, p = 0.08). The UCLA score was 7.0 (± 1.9) in the AAD group and 6.8 (± 1.8) in the TAR group (p = 0.78). The AOFAS score reached 75.6 (± 14) in the AAD group and 75.6 (± 16) in the TAR group (p = 0.97). The ankle activity score decrease was statistically significant for both groups (p = 0.047). Our study revealed no significant difference between the groups concerning activity levels, participation in sports activities, UCLA and AOFAS score. After AAD the number of patients participating in sports decreased. However, this change was not statistically significant.

Polio infection can often lead to orthopedic complications such as arthritis, osteoporosis, muscle weakness, skeletal deformation, and chronic instability of the joints. The purpose of this study was to assess the outcomes and associated complications of arthroplasty in shoulders with sequelae of poliomyelitis. Seven patients (average age, 70 years) were treated between 1976 and 2013 with shoulder arthroplasty for the sequelae of polio. One patient underwent reverse shoulder arthroplasty, 2 had a hemiarthroplasty, and 4 had total shoulder arthroplasty. Average follow-up was 87 months. Outcome measures included pain, range of motion, and postoperative modified Neer ratings. Overall pain scores improved from 5 to 1.6 points (on a 5-point scale) after shoulder arthroplasty. Six shoulders had no or mild pain at latest follow-up, and 6 shoulders rated the result as much better or better. Mean shoulder elevation improved from 72° to 129°, and external rotation improved from 11° to 56°. Average strength in elevation decreased from 3.9 to 3.4 postoperatively, and external rotation strength decreased from 3.9 to 3.3. This, however, did not reach significance. Evidence of muscle imbalance with radiographic instability was found in 4 shoulders that demonstrated superior subluxation, anterior subluxation, or both. This remained asymptomatic. No shoulder required revision or reoperation. Shoulder arthroplasty provides significant pain relief and improved motion in patients with sequelae of poliomyelitis. Muscle weakness may be responsible for postoperative instability, and careful selection of the patient with good upper extremity muscles must be made.

It is common for patients to require staged bilateral shoulder arthroplasties. There is a unique cohort of patients who require an anatomic total shoulder arthroplasty (TSA) and a contralateral reverse shoulder arthroplasty (RSA). This study compared the outcomes of patients with a TSA in 1 shoulder and an RSA in the contralateral shoulder. Our institutional database was queried to identify all patients with a TSA and a contralateral RSA. Data collection included patient demographics, preoperative and latest follow-up shoulder range of motion, radiographic analysis, and postoperative complications. Identified patients were assessed at follow-up visits or contacted by phone for functional outcome scores. Nineteen patients met our inclusion/exclusion criteria. There was statistically significant greater internal rotation in the TSA shoulder (P= .044) but no significant difference in forward elevation (P = .573) or external rotation (P= .368). There was no radiographic evidence of humeral or glenoid component loosening of any arthroplasty implants. There were no significant differences between TSA and RSA shoulders for the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment (P= .381), Simple Shoulder Test (P = .352), Single Assessment Numerical Evaluation (P = .709), and visual analog scale satisfaction (P= .448) or pain scores (P= .305). Thirteen patients (68.4%) preferred the RSA side, 1 patient (5.3%; z = 4.04, P < .001) patient preferred the TSA side, and 5 patients expressed no preference. Despite known limitations and differences between TSA and RSA designs, patients who have received both implants are highly satisfied with both. The only parameter in which the TSA had superior outcomes was internal rotation. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

2013-06-01

The purpose of this paper is to provide up-to-date guidelines on rehabilitation after anatomical shoulder prosthesis for concentric shoulder osteoarthritis, as previous guidelines date back to late 1970s and are no longer adequate due to the evolution of prosthesis models and surgical techniques. The physiatric committee of the Italian Society of Shoulder and Elbow Surgery (SICSeG-Società Italiana di Chirurgia della Spalla e del Gomito) performed a search for all the existing literature related to rehabilitation after shoulder replacement. A total of 29 papers concerning shoulder rehabilitation were reviewed. In addition, the main Italian orthopedic surgeons and physiatrists dealing with shoulder surgery and rehabilitation were interviewed to obtain indications when literature was not conclusive. From literature evaluation and expert consultation, we produced guidelines concerning: patient evaluation by means of adequate rating scales, preoperative treatment, early intermediate and advanced postoperative phases, rehabilitation of scapulo-thoracic joint, return to work and sports, length of rehabilitation and follow-up. This proposal for guidelines was presented during the 11th SICSeG Congress on May 2012 and to the main scientific societies concerned in shoulder surgery and rehabilitation. A consensus conference is needed in order to formalize and make them usable from all the professional figures involved in this field.

Sex, shoulder pain, and range of motion in manual wheelchair users.

PubMed

Wessels, Karla K; Brown, Jennifer L; Ebersole, Kyle T; Sosnoff, Jacob J

2013-01-01

Upwards of 70% of manual wheelchair users (MWUs) experience shoulder pain. Pain is more prevalent among females than males. The causes of this sex discrepancy are not understood. Decreased range of motion (ROM) has been suggested as a major contributor, but the interaction of sex, ROM, and shoulder pain has not been investigated, thus the purpose of this investigation. We divided 30 MWUs (18 males, 12 females; 21.93 +/- 3.77 yr) into two groups based on self-reported shoulder pain: pain group (n = 14; 9 males, 5 females) and no pain group (n = 16; 9 males, 7 females). We used a digital goniometer to assess ROM. Participants' shoulder active and passive ROMs were tested bilaterally on the following joint motions: flexion, extension, abduction, adduction, internal rotation, and external rotation. We used a visual analog scale to assess shoulder pain. Of the participants, 47% reported shoulder pain. Overall, the no pain group had greater ROM than the pain group, with further analysis revealing this association was only significant in females during extension (p < 0.05). ROM impairments were only present in extension in females with shoulder pain. The mechanism underlying this sex difference is not clear.

2017-01-01

The purpose of this study was to evaluate the postural and muscular demands placed on the shoulders and neck of dental hygienists when performing a simulated manual scaling task. Nineteen healthy female dental hygienists performed 30-min of simulated manual scaling on a manikin head in a laboratory setting. Surface electromyography was used to monitor muscle activity from several neck and shoulder muscles, and neck and arm elevation kinematics were evaluated using motion capture. The simulated scaling task resulted in a large range of neck and arm elevation angles and excessive low-level muscular demands in the neck extensor and scapular stabilising muscles. The physical demands varied depending on the working position of the hygienists relative to the manikin head. These findings are valuable in guiding future ergonomics interventions aimed at reducing the physical exposures of dental hygiene work. Practitioner Summary: Given that this study evaluates the physical demands of manual scaling, a procedure that is fundamental to dental hygiene work, the findings are valuable to identify ergonomics interventions to reduce the prevalence of work-related injuries, disability and the potential for early retirement among this occupational group.

The knowledge-attitude dissociation in geriatric education: can it be overcome?

A knowledge-attitude dissociation often exists in geriatrics where knowledge but not attitudes towards elderly patients improve with education. This study aims to determine whether a holistic education programme incorporating multiple educational strategies such as early exposure, ageing simulation and small group teaching results in improving geriatrics knowledge and attitudes among medical students. We administered the 18-item University of California Los Angeles (UCLA) Geriatric Knowledge Test (GKT) and the Singapore-modified 16-item UCLA Geriatric Attitudes Test (GAT) to 2nd year students of the old curriculum in 2009 (baseline reference cohort, n = 254), and before and after the new module to students of the new curriculum in 2010 (intervention cohort, n = 261), both at the same time of the year. At baseline, between the baseline reference and intervention cohort, there was no difference in knowledge (UCLA-GKT Score: 31.6 vs 33.5, P = 0.207) but attitudes of the intervention group were worse than the baseline reference group (UCLA-GAT Score: 3.53 vs 3.43, P = 0.003). The new module improved both the geriatric knowledge (UCLA-GKT Score: 34.0 vs 46.0, P <0.001) and attitudes (UCLA-GAT Score: 3.43 vs 3.50, P <0.001) of the intervention cohort. A geriatric education module incorporating sound educational strategies improved both geriatric knowledge and attitudes among medical students.

In the literature it has been shown that posterior capsule flexibility is a precursor to shoulder problems. However, no study thus far has shown the influence of the flexibility of posterior capsule in different shoulder pathologies. This study set about to compare the role of posterior capsule tightness in different shoulder problems. One-hundred-twenty-five patients diagnosed with shoulder subacromial impingement syndrome (n= 52), partial rotator cuff tear (n= 31) or frozen shoulder (n= 42) and 30 asymptomatic peers participated in the study. Horizontal adduction was assessed in side-lying position for posterior capsule tightness. Pain was measured via the visual analogue scale and shoulder range of motion and active total elevation was assessed with goniometer. Hand behind the back (HBB) test was assessed the active internal rotation by measuring the distance between T5 and the thumb. It was found that the affected side of the posterior capsules of the patients with subacromial impingement syndrome (p< 0.001), partial rotator cuff tear (p< 0.001) and frozen shoulder (p< 0.001) was stiffer than their healthy side. There were significant differences among groups in the level of tightness in the posterior capsule between the affected and the healthy sides (p< 0.001). All range of motion of the shoulder including HBB test and the posterior capsule tightness of the affected side are found to be correlated (p< 0.05). This study emphasized that the posterior capsule's susceptibility to tightness is most evident in frozen shoulder among different shoulder problems.

Hypothesis/Purpose: The purpose was to determine the effect of an injection of adipose-derived MSCs loaded in fibrin glue during arthroscopic rotator cuff repair on clinical outcomes and to evaluate its effect on structural integrity using magnetic resonance imaging (MRI). The hypothesis was that the application of adipose-derived MSCs would improve outcomes after the surgical repair of a rotator cuff tear. Cohort study; Level of evidence, 3. Among 182 patients treated with arthroscopic surgery for a rotator cuff tear, 35 patients treated with arthroscopic rotator cuff repair alone (conventional group) were matched with 35 patients who underwent arthroscopic rotator cuff repair with an injection of adipose-derived MSCs loaded in fibrin glue (injection group) based on sex, age, and lesion size. Outcomes were assessed with respect to the visual analog scale (VAS) for pain, range of motion (ROM) (including forward flexion, external rotation at the side, and internal rotation at the back), and functional measures of the Constant score and University of California, Los Angeles (UCLA) shoulder rating scale. Repaired tendon structural integrity was assessed by using MRI at a minimum of 12 months after surgery, and the mean clinical follow-up was 28.8 ± 4.2 months in the conventional group and 28.3 ± 3.8 months in the injection group. The mean VAS score at rest and during motion improved significantly in both groups after surgery. However, there were no significant differences between the groups at the final follow-up ( P = .256 and .776, respectively). Compared with preoperative measurements, forward flexion and external rotation at the side significantly improved at the final follow-up in both groups (all P < .05). However, no significant improvements in internal rotation at the back were observed in either group ( P = .625 and .834 for the conventional and injection groups, respectively). There were also no significant differences between the groups at the final follow-up for any of the 3 ROM positions (all P > .05). The mean Constant score and UCLA score improved significantly in both groups after surgery, but there were no significant differences between the groups at the final follow-up ( P = .634 and .302, respectively). MRI indicated a retear rate of 28.5% in the conventional group and 14.3% in the injection group ( P < .001). This study revealed that an injection of adipose-derived MSCs loaded in fibrin glue during rotator cuff repair could significantly improve structural outcomes in terms of the retear rate. There were, however, no clinical differences in the 28-month period of follow-up. Although still in the early stages of application, MSC augmentation of surgical rotator cuff repair appears useful for providing an adequate biological environment around the repair site.

The aim of this study is (1) to investigate the prevalence rate of arm lymphedema, pain, impaired shoulder range of motion, strength and shoulder function one year after a sentinel lymph node biopsy (SLNB) for breast cancer and (2) to determine predictive factors for these complications. A longitudinal study was performed. One hundred patients with a sentinel-lymph node negative breast cancer were included. All patients were measured before surgery and one year after. Arm lymphedema was measured with the perimeter, pain with the Visual Analogue Scale, shoulder range of motion with an inclinometer, strength with a handheld dynamometer and shoulder function with the Disability of Arm, Shoulder and Hand questionnaire. Patient-, breast cancer- and treatment-related variables were recorded. One year after surgery 8% of sentinel node-negative breast cancer patients had developed arm lymphedema. Fifty percent of patients had pain, 30% had an impaired shoulder range of motion, 8% had a decreased handgrip strength and 49% had an impaired shoulder function. Pain, shoulder range of motion, strength and shoulder dysfunctions changed significantly over one year (p < 0.001). Higher Body Mass Index is a predictive variable for shoulder dysfunctions one year post-SLNB. Prevalence rate of lymphedema and other upper limb impairments may not be underestimated after SLNB. Pain, shoulder range of motion, handgrip strength and shoulder function change significantly up to one year compared to preoperative values in sentinel node-negative breast cancer patients.

The purpose of this study was to evaluate the radiologic and clinical outcomes of coracoclavicular (CC) stabilization using a suture button device for Neer type IIB lateral clavicle fractures. Eighteen consecutive patients with Neer type IIB fractures were treated with CC stabilization using a TightRope device (Arthrex, Naples, FL, USA). The mean follow-up period was 46.6 months (range, 24-75 months). Radiologic outcomes were assessed using serial plain radiographs. Clinical outcomes were evaluated using the visual analog scale pain score; University of California, Los Angeles score; American Shoulder and Elbow Surgeons score; and subjective shoulder value. Intraoperative and postoperative complications were also evaluated. Of the 18 cases, 17 (94.4%) showed complete bony union. The mean final visual analog scale pain score was 1.1; University of California, Los Angeles score, 31.3; American Shoulder and Elbow Surgeons score, 88.6; and subjective shoulder value, 88.5%. Four complications were observed: (1) intraoperative coracoid process fracture, (2) nonunion, (3) delayed union, and (4) shoulder stiffness. The case with a coracoid process fracture during coracoid tunnel generation was converted to the K-wire tension band technique. CC stabilization using a suture button device for Neer type IIB lateral clavicle fractures yielded satisfactory radiologic and clinical outcomes. The major advantage of this technique is that implant removal is not required. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

To measure the effects of Bobath-based (BB) therapy on depression, shoulder pain and health-related quality of life (HRQoL) of patients during one year after stroke. In a prospective, non-randomized design, the use of BB therapy was compared with a more task-oriented therapy and no BB therapy. A total of 324 patients in 12 hospitals. Patients in the intervention group received BB therapy, whereas patients in the control group received no BB therapy and a more task-oriented therapy. HRQoL was measured using the SF-36; depression was measured with the Center of Epidemiological Studies Depression Scale and shoulder pain was measured with the Visual Analogue Scale at discharge, 6 and 12 months. Linear and logistic regression analyses were performed. No effects of BB therapy on HRQoL or shoulder pain were found. After one year fewer patients were depressed in the BB group (30%) than in the non-BB group (43%); the adjusted odds ratio was 0.6 (95% confidence interval 0.3-1.0). BB therapy did not have any effect on HRQoL or shoulder pain in stroke patients. Healthcare professionals should reconsider the use of BB therapy in the care of stroke patients.

A rotator cuff tear is a relatively frequent cause of pain and restricted motion of the shoulder. Some orthopaedists believe that any attempt at rotator cuff reconstruction will fail. The aim of this paper is to present our experience with arthroscopic reconstruction of rotator cuff tears. Between January 1998 and December 2008, 319 patients with an early diagnosis of rotator cuff rupture were treated. The group included 67 women and 252 men, with an average age of 37 years (range, 24 to 71 years) at the time of surgery. The patients indicated for arthroscopic reconstruction had to show free motion of the shoulder, had a full thickness tear up to 3 cm in size in the sagittal plane and a Patte stage 2 tear in the frontal plane at the maximum. The outcome of surgery was evaluated at one year of follow-up and included the patient's self-assessment, modified UCLA score and incidence of complications. The probability of failure was calculated as an odds ratio of an implant failure to failure of the other implants and the probability of repeat surgery in a given implant was calculated as a relative risk in relation to the other implants. The average operative time was 52 minutes (range, 25 to 85); the average UCLA score increased from 10 to 31 points (p<0.00001). An excellent or a good result was achieved in 80% of the patients. Rotator cuff reconstruction failed in 32 patients (11%), of whom 22 (7.6%) underwent revision surgery. The failure was due to migration of rotator cuff anchors or thread failure in 14 patients (14/32; 44%). The GII anchors showed the highest risk of failure, with the odds ratio of 5.55 (95 % CI, 2.22 to 13.84) for mechanical failure of the method and a relative risk of revision surgery of 7.62 (95% CI, 2.86 to 20.27). For comparison, the RC anchors had the odds ratio for mechanical failure equal to 0.55 (95 % CI, 0.25 to 1.24) and the relative risk of repeat surgery equal to 0.41 (95% CI, 0.12 to 1.43). In addition, 18 complications were recorded. The frequency of deep wound infection was 0.7% (2/319). Six patients (2.1%) required repeat surgery for symptomatic bursitis and adhesive capsulitis. A recent meta-analysis has found no significant difference between the results of surgical rotator cuff reconstruction and its conservative treatment. We do not support this view but present here evidence that, when certain conditions are fulfilled, arthroscopic reconstruction can produce a very good clinical outcome. The arthroscopic reconstruction of a rotator cuff tears results in a marked relief of pain and improved joint function. An ideal candidate for this treatment should show passive free motion at the shoulder joint, no clinical signs of bursitis, and mobilisable tendon stumps of the torn rotator cuff. In addition, these patients should be highly motivated for post-operative rehabilitation. A suture device was most effective in rotator cuff repair. For good fixation into the bone it is recommended to use special implants that have a minimal risk of dislodgement or anchor thread failure.

The incidence of asymptomatic rotator cuff tears has been reported to range from 15% to 39%, but the influence of asymptomatic rotator cuff pathology on shoulder function is not well understood. This study assessed the effects of asymptomatic rotator cuff pathology on shoulder kinematics, strength, and patient-reported outcomes. A clinical ultrasound examination was performed in 46 asymptomatic volunteers (age: 60.3 ± 7.5 years) with normal shoulder function to document the condition of their rotator cuff. The ultrasound imaging identified the participants as healthy (n = 14) or pathologic (n = 32). Shoulder motion was measured with a biplane x-ray imaging system, strength was assessed with a Biodex (Biodex Medical Systems, Inc., Shirley, NY, USA), and patient-reported outcomes were assessed using the Western Ontario Rotator Cuff Index and visual analog scale pain scores. Compared with healthy volunteers, those with rotator cuff pathology had significantly less abduction (P = .050) and elevation (P = .041) strength, their humerus was positioned more inferiorly on the glenoid (P = .018), and the glenohumeral contact path length was longer (P = .007). No significant differences were detected in the Western Ontario Rotator Cuff Index, visual analog scale, range of motion, or acromiohumeral distance. The differences observed between the healthy volunteers and those with asymptomatic rotator cuff pathology lend insight into the changes in joint mechanics, shoulder strength, and conventional clinical outcomes associated with the early stages of rotator cuff pathology. Furthermore, these findings suggest a plausible mechanical progression of kinematic and strength changes associated with the development of rotator cuff pathology.

Although ultrasound (US)-guided subacromial injection has shown increased accuracy in needle placement, whether US-guided injection produces better clinical outcome is still controversial. Therefore, this study aimed to compare the efficacy of subacromial corticosteroid injection under US guidance with palpation-guided subacromial injection in patients with chronic subacromial bursitis. Patients with chronic subacromial bursitis were randomized to a US-guided injection group and a palpation-guided injection group. The subjects in each group were injected with a mixture of 0.5 mL dexamethasone suspension and 3 mL lidocaine into the subacromial bursa. The primary outcome measures were the visual analog scale for pain and active and passive ranges of motion of the affected shoulder. Secondary outcome measures were the Shoulder Pain and Disability Index, the Shoulder Disability Questionnaire, and the 36-item Short-Form Health Survey (SF-36). The primary outcome measures were evaluated before, immediately, 1 wk, and 1 month after the injection; the secondary outcome measures were evaluated before, 1 wk, and 1 month after the injection. Of the 145 subjects screened, 46 in each group completed the study. Significantly greater improvement in passive shoulder abduction and in physical functioning and vitality scores on the SF-36 were observed in the US-guided group. The pre- and postinjection within-group comparison revealed significant improvement in the visual analog scale for pain and range of motion, as well as in the Shoulder Pain and Disability Index, Shoulder Disability Questionnaire, and SF-36 scores, in both groups. The US-guided subacromial injection technique produced significantly greater improvements in passive shoulder abduction and in some items of the SF-36. US is effective in guiding the needle into the subacromial bursa in patients with chronic subacromial bursitis.

Current literatures describe good clinical outcomes of acute displaced fracture of clavicle treated with minimally invasive plate osteosynthesis (MIPO). But, there are little comparative data of the outcomes between open plating and MIPO techniques. We compared the outcomes of open plating and MIPO for treatment of acute displaced clavicular shaft fractures. The author performed a retrospective review on a consecutive series of patients with clavicular shaft fracture who underwent open plating or MIPO. Fourteen patients were treated with open plating with interfragmentary screw fixation, and 19 were treated with the MIPO technique without exposing a fracture site itself. A superior plating method was applied to both groups. Patient demographics, clinical outcomes using Constant score and University of California Los Angeles (UCLA) shoulder score, operation time, union rate, complications, and radiographic evaluation were evaluated. There were no statistically significant differences in the demographic data, including patient's variables (age, gender, involved side, smoking, alcohol, and diabetic status) and fracture characteristics (trauma mechanism, distribution of fracture type, presence of polytrauma, and time from trauma to surgery) between the two groups. Mean operation time was 87.5 min in open plating and 77.2 min in MIPO (p=0.129). The mean time to union was 15.7 weeks in patients who underwent open plating and 16.8 weeks in patients who underwent MIPO (p=0.427). Although there was no significant difference, nonunion developed 1 case in MIPO while none was in open plating. Four patients in open plating had skin numbness (none in MIPO, p=0.024). There was no significant difference in the Constant score and UCLA score of the two surgical methods. This study showed that both open plating with interfragmentary screw fixation (Open plating) and minimally invasive plate osteosynthesis (MIPO) are equally effective and safe treatment methods for acute displaced clavicle shaft fracture.

The aim of our study was to evaluate the shoulder function after clavicular hook plate fixation of acute acromioclavicular dislocations (Rockwood type III) in a population group consisting exclusively of high-demand military personnel. This prospective study was carried out at a tertiary care military orthopaedic centre during 2012-2013 using clavicular hook plate for management of acromioclavicular injuries without coracoclavicular ligament reconstruction in 33 patients. All patients underwent routine implant removal after 16 weeks. The functional outcome was assessed at 3, 6 and 12 months after hook plate removal and 2 years from the initial surgery using the Constant Murley and UCLA Scores. All the patients were male serving soldiers and had sustained acromioclavicular joint dislocation (Rockwood type III). Mean age of the patient group was 34.24 years (21-55 years). The mean follow-up period in this study was 23.5 months (20-26 months) after hook plate fixation and an average of 19.9 months (17-22 months) after hook plate removal. The average Constant Score at 3 months after hook plate removal was 60.3 as compared to 83.7 and 90.3 at 6 months and 1 year, respectively, and an average of 91.8 at the last follow-up that was approximately 2 years after initial surgery which was statistically significant (p value <0.05). The UCLA Score was an average of 15.27, 25.9 and 30.1 at 3, 6 months and 1 year, respectively, after removal of hook plate which improved further an average of 32.3 at the last follow-up, which was also statistically significant (p value <0.05). Clavicular hook plate fixation without coracoclavicular ligament reconstruction is a good option for acute acromioclavicular dislocations producing excellent medium-term functional results in high-demand soldiers.

Service-learning is a pedagogy that combines academic rigor with activities that address human and community needs. Over the past three years, we have developed a service-learning course that involves UCLA students working with 6th graders in an economically disadvantaged neighborhood to address issues of environmental science and health. This past year UCLA students conducted a research project in collaboration with a middle school class to investigate levels of pathogen-indicating organisms in beach sand near the Santa Monica pier. All students were taught necessary methods in class by the UCLA professor, and then met at the field site. Fieldwork involved collection of water and sand samples from various locations, extraction of bacteria from sand by shaking with buffer and decanting, and addition of sample to growth media that allow quantification of two organisms, Escherichia coli and enterococci. These organisms are typically used to indicate fecal contamination of water. Methods were straightforward and were accomplished by the 6th graders with only modest supervision by the UCLA students. Results showed extremely high levels of pathogen indicating organisms in the vicinity of a diverted stormdrain, indicating a continuing problem with the diversion. Levels decreased with distance away from the stormdrain, indicating migration of the organisms from the site of the diversion. UCLA students then visited the sixth grade classroom to help the sixth graders create Powerpoint posters including statement of hypotheses, graphs of the results, pictures of the entire process, and conclusions. Middle school students then visited UCLA to tour the campus and present their posters at a poster session hosted by the Center for Embedded Networked Sensing at UCLA. Desired outcomes at the 6th grade level included: 1) increased interest in science; 2) greater knowledge of and interest in attending college; and 3) enhanced knowledge of and feeling of political empowerment concerning environmental health issues. Outcomes for the UCLA students included: 1) gains in learning through the action of teaching; 2) awareness of education justice issues in Los Angeles; and 3) enhanced feeling of personal commitment to community and political advocacy work.

Wet cupping therapy (WCT) is a traditional complementary method recommended to decrease the symptoms of a lot of diseases and used in the treatment of pain syndromes. In this pilot study, the possible effects of wet cupping therapy on nonspecific neck and upper shoulder pain were investigated. Sixty one eligible volunteer participants with nonspecific neck and upper shoulder pain for at least 3 months were allocated. The Numeric Rating Scale (NRS) was used to assess pain scores. Pain scores were recorded before and after wet cupping therapy. The mean scores of neck pain in study group were 7.02 (SD = 1.8) before and 3.70 (SD = 2.2) after cupping therapy. The decrease of pain scores between pre- and post-test was statistically significant (p < 0.05). It can be stated that WCT has potential therapeutic effect in nonspecific neck and upper shoulder pain. Future full-scale randomized controlled trials will be needed to provide firm evidence of the effectiveness of this intervention. Copyright © 2016 Elsevier Ltd. All rights reserved.

OBJECTIVE—To study the effect of accuracy on the clinical outcome of local steroid injections to the shoulder.
METHODS—37 patients with shoulder symptoms of at least two months' duration received local injections of a mixture of triamcinolone and radiographic contrast material using a standardised technique. Radiographs of the joint were taken immediately afterwards. Details of the patients' symptoms (assessed by visual analogue scales) and range of movement at the joint were obtained before and two weeks after the injection. At follow up the patients were also assessed by means of a five point global rating scale of maximum and current benefit.
RESULTS—14 of the 38 procedures (37%) were judged to be accurately placed: four of the 14 attempted subacromial injections (29%) and 10 of the 24 attempted glenohumeral injections (42%). There were significant differences in relation to outcome between the accurately placed and the inaccurately placed groups.
CONCLUSIONS—Accuracy of steroid placement by injection in patients with shoulder symptoms may significantly affect the clinical outcome.

To (1) investigate the immediate effects of myofascial induction (MI), with placebo electrotherapy as a control, on perceived pain, cervical/shoulder range of motion (ROM), and mood state in breast cancer survivors (BCSs) with shoulder/arm morbidity; and (2) examine the relationships between pain modifications and cervical/shoulder ROM on the side affected by breast cancer. Randomized, single-blind, placebo-controlled crossover study. Physical therapy laboratory. BCSs (N=21) who had a diagnosis of stage I-IIIA breast cancer and had completed adjuvant therapy (except hormonal treatment). During each session, the BCSs received either an MI (fascial unwinding) intervention focused on the upper limb area following the Pilat approach or placebo pulsed shortwave therapy (control group). Each session lasted 30 minutes, and an adequate washout period of 4 weeks between sessions was established. The visual analog scale (VAS) for pain and anxiety, shoulder-cervical goniometry for ROM, the Profile of Mood States for psychological distress, and the Attitudes Towards Massage Scale were used. An analysis of covariance (ANCOVA) revealed significant time × group interactions for VAS affected arm (P=.031) but not for VAS cervical (P=.332), VAS nonaffected arm (P=.698), or VAS anxiety (P=.266). The ANCOVA also revealed significant interactions for affected shoulder flexion (P<.001), abduction (P<.001), external rotation (P=.004), and internal rotation (P=.001). Significant interactions for affected cervical rotation (P=.022) and affected cervical lateral flexion (P=.038) were also found. A significant negative correlation was found between changes in VAS affected arm and shoulder/arm internal rotation ROM (r=-.46; P=.03). A single MI session decreases pain intensity and improves neck-shoulder ROM to a greater degree than placebo electrotherapy for BCSs experiencing pain.

Shoulder disorders are a common cause of disability and pain. The Shoulder Pain and Disability Index (SPADI) is a frequently employed and previously validated measure of shoulder pain and disability. Although the SPADI has high reliability and construct validity, greater differences between individual patients are often observed than would be expected on the basis of diagnosis and pathophysiology alone. This study aims to determine how psychological factors (namely depression, catastrophic thinking, and self-efficacy) affect pain and perceived disability in the shoulder. A cohort of 139 patients completed a sociodemographic survey and elements from the SPADI, Pain Self-Efficacy Questionnaire (PSEQ), Pain Catastrophizing Scale (PCS), and Patient Health Questionnaire Depression Scale (PHQ-2). Bivariate and multivariate analyses were performed to determine the association of psychosocial factors, demographic characteristics, and specific diagnosis with shoulder pain and disability. The SPADI score showed medium correlation with the PCS (r = 0.43; p < 0.001), PHQ-2 (r = 0.39; p < 0.001), and PSEQ (r = -0.45; p < 0.001). Current work status (F = 4.35; p = 0.006) and body mass index (r = 0.27; p = 0.002) were also associated with the SPADI score. In the multivariate analysis, greater catastrophic thinking (estimate, 0.003; p = 0.029), lower self-efficacy (estimate, -0.005; p = 0.001), higher body mass index (estimate, 0.006; p = 0.048), and being disabled (estimate, 0.15; p = 0.017) or retired (estimate, 0.16; p < 0.001) compared with being employed were associated with worse SPADI scores. The primary diagnosis did not have a significant relationship (p > 0.05) with the SPADI. Catastrophic thinking and decreased self-efficacy are associated with greater shoulder pain and disability. Our data support the notion that patient-to-patient variation in symptom intensity and magnitude of disability is more strongly related to psychological distress than to the specific shoulder diagnosis.

Double-row arthroscopic rotator cuff repairs were developed to improve initial biomechanical strength of repairs to improve healing rates. Despite biomechanical improvements, failure of healing remains a clinical problem. To evaluate the anatomical results after double-row arthroscopic rotator cuff repair with ultrasound to determine postoperative repair integrity and the effect of various factors on tendon healing. Case series; Level of evidence, 4. Forty-eight patients (49 shoulders) who had a complete arthroscopic rotator cuff repair (double-row technique) were evaluated with ultrasound at a minimum of 6 months after surgery. Outcome was evaluated at a minimum of 1-year follow-up with standardized history and physical examination, visual analog scale for pain, active forward elevation, and preoperative and postoperative shoulder scores according to the system of the American Shoulder and Elbow Surgeons and the Simple Shoulder Test. Quantitative strength was measured postoperatively. Ultrasound and physical examinations were performed at a minimum of 6 months after surgery (mean, 16 months; range, 6 to 36 months) and outcome questionnaire evaluations at a minimum of 12 months after surgery (mean, 29 months; range, 12 to 55 months). Of 49 repairs, 25 (51%) were healed. Healing rates were 67% in single-tendon tears (16 of 24 shoulders) and 36% in multitendon tears (9 of 25 shoulders). Older age and longer duration of follow-up were correlated with poorer tendon healing (P < .03). Visual analog scale for pain, active forward elevation, American Shoulder and Elbow Surgeons scores, and Simple Shoulder Test scores all had significant improvement from baseline after repair (P < .0001). Increased age and longer duration of follow-up were associated with lower healing rates after double-row rotator cuff repair. The biological limitation at the repair site, as reflected by the effects of age on healing, appears to be the most important factor influencing tendon healing, even after maximizing repair biomechanical strength with a double-row construct.

Prof M. G. Kivelson and Dr. K. K. Khurana (UCLA (University of California, Los Angeles)) are co-investigators on the Cluster Magnetometer Consortium (CMC) that provided the fluxgate magnetometers and associated mission support for the Cluster Mission. The CMC designated UCLA as the site with primary responsibility for the inter-calibration of data from the four spacecraft and the production of fully corrected data critical to achieving the mission objectives. UCLA will also participate in the analysis and interpretation of the data. The UCLA group here reports its excellent progress in developing fully intra-calibrated data for large portions of the mission and an excellent start in developing inter-calibrated data for selected time intervals, especially extended intervals in August, 2001 on which a workshop held at ESTEC in March, 2002 focused. In addition, some scientific investigations were initiated and results were reported at meetings.

The librarian as research informationist: a case study.

How can an embedded research informationist add value to the scientific output of research teams? The University of California-Los Angeles (UCLA) Louise M. Darling Biomedical Library is an academic health sciences library serving the clinical, educational, and research needs of the UCLA community. A grant from the National Library of Medicine funded a librarian to join a UCLA research team as an informationist. The informationist meets regularly with the research team and provides guidance related to data management, preservation, and other information-related issues. Early results suggest that the informationist's involvement has influenced the team's data gathering, storage, and curation methods. The UCLA Library has also changed the librarian's title to research informationist to reflect the new activities that she performs. The research informationist role provides an opportunity for librarians to become effective members of research teams and improve research output.

This follows reporting of the primary outcomes of implant accuracy and gait analysis that showed significant advantages in the robotic arm-assisted group. A total of 139 patients were recruited from a single centre. Patients were randomised to receive either a manual UKA implanted with the aid of traditional surgical jigs, or a UKA implanted with the aid of a tactile guided robotic arm-assisted system. Outcome measures included the American Knee Society Score (AKSS), Oxford Knee Score (OKS), Forgotten Joint Score, Hospital Anxiety Depression Scale, University of California at Los Angeles (UCLA) activity scale, Short Form-12, Pain Catastrophising Scale, somatic disease (Primary Care Evaluation of Mental Disorders Score), Pain visual analogue scale, analgesic use, patient satisfaction, complications relating to surgery, 90-day pain diaries and the requirement for revision surgery. From the first post-operative day through to week 8 post-operatively, the median pain scores for the robotic arm-assisted group were 55.4% lower than those observed in the manual surgery group (p = 0.040).At three months post-operatively, the robotic arm-assisted group had better AKSS (robotic median 164, interquartile range (IQR) 131 to 178, manual median 143, IQR 132 to 166), although no difference was noted with the OKS.At one year post-operatively, the observed differences with the AKSS had narrowed from a median of 21 points to a median of seven points (p = 0.106) (robotic median 171, IQR 153 to 179; manual median 164, IQR 144 to 182). No difference was observed with the OKS, and almost half of each group reached the ceiling limit of the score (OKS > 43). A greater proportion of patients receiving robotic arm-assisted surgery improved their UCLA activity score.Binary logistic regression modelling for dichotomised outcome scores predicted the key factors associated with achieving excellent outcome on the AKSS: a pre-operative activity level > 5 on the UCLA activity score and use of robotic-arm surgery. For the same regression modelling, factors associated with a poor outcome were manual surgery and pre-operative depression. Robotic arm-assisted surgery results in improved early pain scores and early function scores in some patient-reported outcomes measures, but no difference was observed at one year post-operatively. Although improved results favoured the robotic arm-assisted group in active patients (i.e. UCLA ⩾ 5), these do not withstand adjustment for multiple comparisons. Cite this article : M. J. G.

To examine whether musculoskeletal shoulder pain and limitations in shoulder range of motion (ROM) at discharge from first rehabilitation are associated with activities and participation restrictions 5 years later in persons with spinal cord injury (SCI). Prospective cohort study. Eight specialized SCI rehabilitation centers. Subjects (N=138) with an SCI admitted for first rehabilitation. Not applicable. Peak power output (POpeak), Wheelchair Skills Test (WST), FIM motor score, ability to transfer, Physical Activity Scale for Individuals with Physical Disabilities (PASIPD), mobility range and social behavior subscales of the Sickness Impact Profile 68 (SIPSOC), and employment status. Mean age of the subjects at discharge was 39 years, 72% were men, 32% had tetraplegia, and in 65% the SCI was motor complete. At discharge, 39% reported shoulder pain and 32% had a limited shoulder ROM. In the analyses of variance, shoulder ROM limitation, but not shoulder pain, was associated with all but 1 outcome at 5 years. In the regression analyses, ROM limitations of the shoulder were negatively associated with the ability to transfer (P=.004), FIM motor scores (P<.001), and return to work (P= .027) 5 years after discharge. No significant associations were found with POpeak, WST performance time, SIPSOC, and PASIPD. The presence of limitations in shoulder ROM, but not shoulder pain, at discharge is associated with limitations in activities and employment status 5 years later.

The purpose of our study was to investigate whether shoulder taping affects shoulder kinematics in injured and previously injured overhead athletes during a seated throw. Twenty-six overhead college athletes threw a handball three times with and without tape, while seated on a chair. An 8-camera Vicon Motion Capture system recorded markers placed on the upper limb and trunk during each of the throwing conditions. Scaled musculoskeletal models of the upper limb were created using OpenSim and inverse kinematics used to obtain relevant joint angles. Shoulder taping had no main effect on external (ER) and internal (IR) rotation range (ROM) of the shoulder, but a significant interaction effect was found (p = 0.003 and 0.02, respectively), depending on previous injury status, whereby both the ER and IR ROM of the shoulder in the group of previously injured athletes decreased when taped (143-138° and 54-51°, respectively), but increased in the group who had never been injured (131-135° and 42-44°, respectively). Maximum abduction range and ball velocity were not affected by the application of shoulder taping, regardless of previous injury status. Thus, application of shoulder taping has a differential effect on maximum shoulder ER and IR ROM during throwing depending on previous injury status. These findings have implications for returning athletes to sport after injury and for screening athletes at risk of injury. Copyright © 2011 Orthopaedic Research Society.

Shoulder sports injuries are relatively common in athletes who perform highly repetitive motions. The purposes of this study were to determine the prevalence of and risk factors for shoulder injuries and to analyze how individual and other sport characteristics contribute to the risk of shoulder injuries among 6 overhead sports, those being swimming, rowing, wrestling, basketball, volleyball, and handball. A cross-sectional study was carried out on 613 Iranian overhead sports athletes in different collegiate sport fields. Data were collected using different questionnaires. A structured questionnaire including demographics, sport characteristics, and also prevalence and risk factors of shoulder pain was used. Visual analogue scale and Disability of the Arm, Shoulder, and Hand questionnaires were used to determine the pain intensity and functional disability, respectively. Point, last 6-month, last year, and lifetime prevalences of shoulder pain were 21.4%, 29%, 38.8%, and 41.6%, respectively. The highest point prevalence was related to the rowing athletes with 31.9% and the lowest for swimming athletes (12.3%). Sex, body mass index, sport level, days of practice per week, and satisfaction with income were found to be significantly correlated with the prevalence of shoulder pain (P < .05 in all instances). For those with shoulder pain, the mean pain intensity and functional disability were 53.8 mm and 15.46%, respectively. The prevalence of shoulder pain in athletes with highly repetitive overhead motions seems to be high. Copyright © 2012 National University of Health Sciences. Published by Mosby, Inc.

This study examined the hypothesis that ipsilateral upper extremity elevation for muscle-sparing thoracotomy procedures contributes to the postoperative shoulder pain. Prospective observational study. Medical center. ASA physical status 1-2 patients undergoing elective lung surgeries including pneumonectomy, lobectomy, and segmentectomy performed through either the anterolateral approach or video-assisted thoracotomy surgery. Postoperative observation of ipsilateral shoulder pain. Postoperative examinations of sites of shoulder pain (clavicle, anterior, lateral,or posterior aspect of acromion, posterior neck, supraspinatus, infraspinatus, and these entire areas) with or without trigger points, visual analog scale score of wound pain, and requested counts of analgesics. The number of patients who suffered from postoperative shoulder pain was 37 of 70 (52.9%). Demographic data, anterolateral/VATS ratio, VAS scores, and requested counts of rescue analgesics requirement were similar in the groups of patients with and without postoperative shoulder pain. The segmentectomy caused a significantly higher incidence of postoperative shoulder pain compared with other procedures (p < 0.05). The supra- and infraspinatus were significantly higher areas of painful regions compared to the other sites. The 16 of 37 patients (43.2%) with shoulder pain showed defined trigger points in their painful areas. These results supported the hypothesis that myofascial involvement contributed, to some extent, to shoulder pain after muscle-sparing thoracotomy with ipsilateral upper extremity elevation.

To assess the pain course after intraarticular injection of a gadolinium-containing contrast material admixed with anesthetic for magnetic resonance (MR) arthrography of the shoulder in relation to internal derangements of the shoulder. Institutional review board approval and informed consent were obtained for this study. The study sample consisted of 655 consecutive patients (249 female, 406 male; median age, 54 years) referred for MR arthrography of the shoulder. Pain level was measured at baseline, directly after intraarticular injection of the gadolinium-containing contrast material admixed with anesthetic, 4 hours after injection, 1 day (18-30 hours) after injection, and 1 week (6-8 days) after injection with a visual analog scale (range, 0-10). MR arthrography was used to assess the following internal derangements: lesions of the rotator cuff tendons and long biceps tendon, adhesive capsulitis (frozen shoulder), fluid in the subacromial bursa, labral tears, and osteoarthritis of the glenohumeral joint. History of shoulder surgery was recorded. Linear regression models were calculated for the dependent variable (difference between follow-up pain and baseline pain), with the independent variable grouping adjusted for age and sex. There was no significant association between pain level over time and internal derangements of the shoulder, nor was there significant association between pain level over time in patients with a history of shoulder surgery and patients without a history of shoulder surgery. Neither internal derangements nor prior surgery have an apparent effect on the pain course after MR arthrography of the shoulder. (c) RSNA, 2010.

Few musculoskeletal models are available to assess shoulder deeper muscle demand during overhead lifting tasks. Our objective was to implement a musculoskeletal model to assess the effect of lifting height and load on shoulder muscle work. A musculoskeletal model scaled from 15 male subjects was used to calculate shoulder muscle work during six lifting tasks. Boxes containing three different loads (6, 12 and 18 kg) were lifted by the subjects from the waist to shoulder or eye level. After optimisation of the maximal isometric force of the model's muscles, the bio-fidelity of the model was improved by 19%. The latter was able to reproduce the subjects' lifting movements. Mechanical work of the rotator cuff muscles, upper trapezius and anterior deltoid was increased with lifting load and height augmentation. In conclusion, the use of a musculoskeletal model validated by electromyography enabled to evaluate the muscle demand of deep muscles during lifting tasks.

Low-Temperature Crystal Structures of the Hard Core Square Shoulder Model.

In many cases, the stability of complex structures in colloidal systems is enhanced by a competition between different length scales. Inspired by recent experiments on nanoparticles coated with polymers, we use Monte Carlo simulations to explore the types of crystal structures that can form in a simple hard-core square shoulder model that explicitly incorporates two favored distances between the particles. To this end, we combine Monte Carlo-based crystal structure finding algorithms with free energies obtained using a mean-field cell theory approach, and draw phase diagrams for two different values of the square shoulder width as a function of the density and temperature. Moreover, we map out the zero-temperature phase diagram for a broad range of shoulder widths. Our results show the stability of a rich variety of crystal phases, such as body-centered orthogonal (BCO) lattices not previously considered for the square shoulder model.

To study the correlation between limited shoulder range of motion in persons with spinal cord injury at discharge and the performance of activities, wheeling performance, transfers and participation one year later. Multicentre prospective cohort study. A total of 146 newly injured subjects with spinal cord injury. Shoulder range of motion was measured at discharge. One year later, Functional Independence Measure (FIM), transfer ability, wheelchair circuit and Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) were assessed. Corrections were made for possible confounding factors (age, gender, level and completeness of injury, time since injury and shoulder pain). All subjects with limited shoulder range of motion at discharge had a lower FIM motor score and were less likely (total group 5 times, and subjects with tetraplegia 10 times less likely) to be able to perform an independent transfer one year later. Subjects with limited shoulder range of motion in the total group needed more time to complete the wheelchair circuit. No significant associations with the PASIPD were found in either group. Persons with spinal cord injury and limited shoulder range of motion at discharge are more limited in their activities one year later than those without limited shoulder range of motion.

To compare 2 different treatment approaches, physical therapy modalities, and joint mobilization versus whole-body cryotherapy (WBC) combined with physical therapy modalities and joint mobilization, for symptoms of adhesive capsulitis (AC) of the shoulder. A randomized trial. Hospital. Patients with AC of the shoulder (N=30). Patients were randomly assigned to 2 groups. The WBC group received physical therapy modalities, passive joint mobilization of the shoulder, and WBC, whereas the non-WBC group received only physical therapy modalities and passive joint mobilization of the shoulder. Visual analog scale (VAS), active range of motion (ROM) of flexion, abduction, internal and external rotation of the shoulder, and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) were measured before and after the intervention. A statistically significant difference between groups was found for the VAS, active ROM of flexion, abduction, internal rotation, and external rotation, and the ASES with greater improvements in the WBC group (Ps<.01). Overall, both groups showed a significant improvement in all outcome measures and ROM measures from pre to post at a level of P<.01. There is significant improvement with the addition of WBC to treatment interventions in this sample of patients. Copyright © 2013 American Congress of Rehabilitation Medicine.

The calibration effort for the Magnetospheric Multiscale Mission (MMS) Analog Fluxgate (AFG) and Digital Fluxgate (DFG) magnetometers is a coordinated effort between three primary institutions: University of California, Los Angeles (UCLA); Space Research Institute, Graz, Austria (IWF); and Goddard Space Flight Center (GSFC). Since the successful deployment of all 8 magnetometers on 17 March 2015, the effort to confirm and update the ground calibrations has been underway during the MMS commissioning phase. The in-flight calibration processes evaluate twelve parameters that determine the alignment, orthogonalization, offsets, and gains for all 8 magnetometers using algorithms originally developed by UCLA and the Technical University of Braunschweig and tailored to MMS by IWF, UCLA, and GSFC. We focus on the processes run at GSFC to determine the eight parameters associated with spin tones and harmonics. We will also discuss the processing flow and interchange of parameters between GSFC, IWF, and UCLA. IWF determines the low range spin axis offsets using the Electron Drift Instrument (EDI). UCLA determines the absolute gains and sensor azimuth orientation using Earth field comparisons. We evaluate the performance achieved for MMS and give examples of the quality of the resulting calibrations.

[Purpose] The aim of the study was to investigate the effect of kinesio tape on pain, range of motion, and disability of the shoulder. [Subjects and Methods] Seventy-four female patients who underwent modified radical mastectomy participated in this study. They were randomly divided into two groups, an experimental group that received kinesio tape for the shoulder joint in addition to a conventional physiotherapy program and a control group that received the physiotherapy program only. Outcome measures included the Visual Analogue Scale, shoulder range of motion, and Shoulder Pain and Disability Index. [Results] The experimental group showed significant differences in all outcome measures both within and between groups. The control group only showed a significant within group difference in shoulder flexion. [Conclusion] Clinicians should be able to recognize the benefits achieved through the use of adjunct treatment options such as kinesio tape in comparison with benefits that can be obtained through the use of individual modalities in physical therapy. Kinesio tape can be suggested and recommended for postmastectomy patients, especially for shoulder pain, range of motion, and disability. PMID:28174439

The Patient-Reported Outcomes Measurement Information System (PROMIS) consists of question banks for health domains through computer adaptive testing (CAT). For patients with glenohumeral arthritis, (1) there would be high correlation between traditional patient-reported outcome (PRO) measures and the PROMIS upper extremity item bank (PROMIS UE) and PROMIS physical function CAT (PROMIS PF CAT), and (2) PROMIS PF CAT would not demonstrate ceiling effects. Cohort study (diagnosis); Level of evidence, 3. Sixty-one patients with glenohumeral osteoarthritis were included. Each patient completed the American Shoulder and Elbow Surgeons (ASES) assessment form, Marx Shoulder Activity Scale, Short Form-36 physical function scale (SF-36 PF), EuroQol 5 Dimensions (EQ-5D) questionnaire, Western Ontario Osteoarthritis Shoulder (WOOS) index, PROMIS PF CAT, and the PROMIS UE. Correlation was defined as high (>0.7), moderate (0.4-0.6), or weak (0.2-0.3). Significant floor and ceiling effects were present if more than 15% of individuals scored the lowest or highest possible total score on any PRO. The PROMIS PF demonstrated excellent correlation with the SF-36 PF ( r = 0.81, P < .0001) and good correlation with the ASES ( r = 0.62, P < .0001), EQ-5D ( r = 0.64, P < .001), and WOOS index ( r = 0.51, P < .01). The PROMIS PF demonstrated low correlation with the Marx scale ( r = 0.29, P = .02). The PROMIS UE demonstrated good correlation with the ASES ( r = 0.55, P < .0001), SF-36 ( r = 0.53, P < .01), EQ-5D ( r = 0.48, P < .01), and WOOS ( r = 0.34, P <.01), and poor correlation with the Marx scale ( r = 0.06, P = .62). There were no ceiling or floor effects observed. The mean number of items administered by the PROMIS PRO was 4. These data suggest that for a patient population with operative shoulder osteoarthritis, PROMIS UE and PROMIS PF CAT may be valid alternative PROs. Additionally, PROMIS PF CAT offers a decreased question burden with no ceiling effects.

This study was to investigate the effects of complex exercise on shoulder range of motion and pain for women with breast cancer-related lymphedema. 69 women participated in this study and then they were randomly allocated to complex exercise group (n = 35) or the conventional decongestive therapy group (n = 34). All subjects received 8 sessions for 4 weeks. To identify the effects on shoulder range of motion and pain, goniometer and visual analog scale were used, respectively. The outcome measurements were performed before and after the 4 week intervention. After 4 weeks, complex exercise group had greater improvements in shoulder range of motion and pain compared with the conventional decongestive therapy group (p < 0.05). These results suggest that complex exercise is beneficial to improve shoulder range of motion as well as pain of the women with breast cancer-related lymphedema. Complex exercise would be useful to improve shoulder range of motion and pain of the women with breast cancer-related lymphedema.

2010-07-01

An examination was made of how differences in the proficiency of massage practitioners had different physical and psychological effects on clients. Eight healthy 50-year-old females, suffering from chronic neck and shoulder stiffness, were recruited and four interventions were conducted: three 40-minute massage therapy interventions, one each by a freshman and a sophomore student studying massage therapy, and one by their instructor, and one rest on the massage table. Visual analogue scale score for muscle stiffness in the neck and shoulder, state anxiety score, and salivary cortisol concentration levels and secretory immunoglobulin A, were measured pre- and post- interventions. Visual analogue scale of neck and shoulder stiffness after massage by the instructor was significantly lower than that after the other interventions, and the score of state anxiety was lower than that after resting.

2018-06-01

The deltopectoral approach for reverse shoulder arthroplasty (RSA) requires subscapularis tenotomy or lesser tuberosity osteotomy. Whether the subscapularis should be repaired at the conclusion of the procedure remains controversial. The present study sonographically assessed the subscapularis after RSA and evaluated the effect of tendon integrity on functional outcome. All patients who had undergone RSA in the Gold Coast University Hospital between 2005 and 2016 were included. Sonography was performed by a blinded examiner. Function was assessed using the Disabilities of the Arm, Shoulder and Hand, the Constant-Murley, and Oxford Shoulder scores. Internal rotation ability was recorded on a 6-point scale. The study included 43 patients (48 shoulders). Median length of follow-up was 19 months (range, 4-132 months). On sonography, the subscapularis was graded intact in 6 shoulders (13%), intact with mild attenuation in 16 (33%), severely attenuated in 15 (31%), and not intact or absent in 11 (23%). Differences in Disabilities of the Arm, Shoulder and Hand, Constant-Murley, or Oxford Shoulder scores between intact and attenuated or absent subscapularis shoulders were not significant. Internal rotation scores were significantly higher in the intact and mildly attenuated tendon group than in the absent tendon group (U = 1.0, P = .001 and U = 28.5, P = .007, respectively). The present work is the first long-term outcome study of RSA using sonography to assess the subscapularis. Subscapularis integrity did not appear to have a measurable effect on patient outcome as measured by standard scores but was important for internal rotation ability after RSA.

Postlaparoscopic shoulder pain (PLSP) remains a common problem after laparoscopies. The aim of this study was to investigate the correlation between pressure pain threshold (PPT) of different muscles and PLSP after gynecologic laparoscopy, and to explore the effect of parecoxib, a cyclooxygenase-2 inhibitor, on the changes of PPT. The patients were randomly allocated into two groups; group P and group C. In group P, parecoxib 40 mg was intravenously infused at 30 minutes before surgery and 8 and 20 hours after surgery. In group C, normal saline was infused at the corresponding time point. PPT assessment was performed 1 day before surgery and at postoperative 24 hours by using a pressure algometer at bilateral shoulder muscles (levator scapulae and supraspinatus) and forearm (flexor carpi ulnaris). Meanwhile, bilateral shoulder pain was evaluated through visual analog scale score at 24 hours after surgery. Preoperative PPT level of the shoulder, but not of the forearm, was significantly and negatively correlated with the intensity of ipsilateral PLSP. In group C, PPT levels of shoulder muscles, but not of forearm muscles, decreased after laparoscopy at postoperative 24 hours. The use of parecoxib significantly improved the decline of PPT levels of bilateral shoulder muscles (all P <0.01). Meanwhile, parecoxib reduced the incidence of PLSP (group P: 45% vs group C: 83.3%; odds ratio: 0.164; 95% confidence interval: 0.07-0.382; P <0.001) and the intensity of bilateral shoulder pain (both P <0.01). Preoperative PPT levels of shoulder muscles are closely associated with the severity of shoulder pain after gynecologic laparoscopy. PPT levels of shoulder muscles, but not of forearm muscles, significantly decreased after surgery. Parecoxib improved the decrease of PPT and relieved PLSP.

Shoulder injuries associated with the throwing and fielding demands of the game are common in elite cricketers. This study aimed to identify the factors associated with shoulder injuries in an elite junior squad. Cross-sectional study. Sixty players aged 15-19 years, from the Cricket Victoria elite junior male squads completed questionnaires and 46 completed clinical assessments conducted by a physiotherapist that included shoulder strength, range of movement and scapula position. Participants were classified into two groups; players currently reporting shoulder problems (SP) and those not reporting shoulder problems (NSP) on the basis of their response to the question 'Have you had any problems with your shoulder in the last 12 months that have affected you training for or playing cricket?'. Fifteen percent (9 of 60) of participants reported shoulder problems (SP). The level of shoulder disability in participants with SP, classified on standard self-report scales, was mild to moderate. The major difference between groups was that the SP group displayed a significant downward rotation of the scapula in almost all shoulder positions. There were no differences between the two groups for training factors, range of motion, or in clinical test results. However, contrary to expectations the SP group exhibited greater strength than the NSP group on some variables. A consistently downwardly rotated scapula associated with young cricketers with SP may predispose these cricketers to ongoing injury through impingement and also through increased load on the rotator cuff muscles acting at the glenohumeral joint during throwing.

To examine the frequency, influencing factors and clinical course of shoulder pain in patients following lung resection. Thoracoscopes have been introduced in the surgical treatment of lung cancer and allow for less invasive surgery with a minimal incision. However, decubitus position-related shoulder pain on the operated side has not yet been investigated. A longitudinal descriptive study. Patients who underwent lung resection in the decubitus position. Patients were interviewed 2 days before surgery and once daily for 5 days after surgery. Interview items included background data, the concomitant use of epidural anaesthesia, operative duration, the presence of preoperative shoulder stiffness (excluding shoulder pain), type of surgery and site of operation. The intensity of pain was approximately 5 on an 11-point numerical rating scale. Descriptive statistics on patient backgrounds were obtained using SPSS Statistics 22 for Windows. Of the 74 patients who underwent lung resection in a decubitus position, 30 (40.5%) developed shoulder pain on the operated side. The highest rating occurred 1 day after surgery and decreased over time. The following two factors were found to influence shoulder pain on the operated side: operative duration (Z = -2.63; p = .01) and the presence of preoperative shoulder stiffness (excluding shoulder pain) (χ 2  = 4.16; p = .04). This study demonstrated that approximately 40% of patients who underwent lung resection in the decubitus position developed shoulder pain. The presence of postoperative shoulder pain was related to both the duration of the operation and to the presence of preoperative shoulder stiffness. Although the shoulder pain resolves within 4 days, it causes the patient additional discomfort and distress. Therefore, further research is needed on positioning for thoracotomy in order to investigate ways to reduce or eliminate this complication of lung surgery. © 2017 John Wiley & Sons Ltd.

Rape is considered a stressful trauma and often with durable consequences. How the aftermath of rape is for young adolescents' girls considering acute stress is an overlooked field and remains to be studied. In this study, we wanted to investigate acute stress among adolescent victims of rape and the psychometric properties of the Acute Stress Checklist for Children (ASC-Kids). A clinical sample (n = 79) of raped girls, 13-17 years old who had turned to a special rape victim unit for treatment, answered the ASC-Kids. ASC-Kids was also given to a group of minor stressed, non-raped adolescents in the same age range (n = 154) together with the University of California at Los Angeles Post-traumatic Stress Disorder Reaction Index (UCLA PTSD RI), and the Sense of Coherence Scale 13 (SOC-13). The scores from the groups were compared and showed significant differences in mean values on all the diagnostic criteria of acute stress disorder. In the clinical group, 36.7% obtained full ASD criteria. ASC-Kids could discriminate well between groups. Cronbach's alpha was found to be excellent, and the correlation between the UCLA PTSD RI and ASC-Kids found to be good; both ASC-Kids and UCLA PTSD RI had a good and moderate negative correlation with SOC-13. Adolescent female rape victims were shown to have a very high level of acute stress, and the ASC-Kids was found to have sound psychometrics and can be a valuable screening instrument to support clinicians in their assessments of an indication of adolescents after potentially stressful events such as rape.

The purpose of this study was to evaluate the early outcome of shoulder tendon transfer in patients with brachial plexus injury and to determine the factors associated with favorable outcomes. Fifty-two patients with traumatic brachial plexus injury and a paralytic shoulder were included in the study. All patients were evaluated at a mean of nineteen months (range, twelve to twenty-eight months) postoperatively. Twelve patients had a C5-6 injury, twenty-two had a C5-7 injury, five had a C5-8 injury, and thirteen had a C5-T1 injury. Transfer of the lower portion of the trapezius muscle was performed either in isolation or as part of multiple tendon transfers to improve shoulder function. Additional muscles transferred included the middle and upper portions of the trapezius, levator scapulae, upper portion of the serratus anterior, teres major, latissimus dorsi, and pectoralis major. All patients had a stable shoulder postoperatively. Shoulder external rotation improved substantially in all patients from no external rotation (hand-on-belly position) to a mean of 20° (p = 0.001). Patients who underwent additional transfers had marginal improvement of shoulder flexion, from a mean of 10° preoperatively to 60° postoperatively, and of shoulder abduction, from a mean of 10° to 50° (p = 0.01 for each). Mean pain on a visual analog scale improved from 6 points preoperatively to 2 points postoperatively. The mean Disabilities of the Arm, Shoulder and Hand (DASH) score improved from 59 to 47 points (p = 0.001). The mean Subjective Shoulder Value improved from 5% to 40% (p = 0.001). Greater age, higher body mass index, and more extensive nerve injury were associated with a poorer DASH score in a multivariate analysis (p = 0.003). Tendon transfers about the shoulder can improve shoulder function in patients with brachial plexus injury resulting in a paralytic shoulder. Significant improvement of shoulder external rotation but only marginal improvements of shoulder abduction and flexion can be achieved. The outcome can be expected to be better in patients with less severe nerve injury.

To perform a systematic review and meta-analysis of randomized controlled trials on the efficacy of workplace-based interventions to prevent or treat shoulder pain. A systematic review of 4 databases was performed up to January 2016. Randomized controlled trials were included if the intervention under study was a workplace-based intervention performed to prevent or reduce shoulder pain and disability in workers. The methodological quality of the studies was evaluated and meta-analyses were conducted. Pooled mean differences and risk ratios were calculated. Data from 4 studies on strengthening exercises performed in the workplace for workers with shoulder pain (n = 368) were pooled. A statistically significant reduction in pain intensity was observed compared with different control interventions (mean differences (scale out of 10) 1.31 (95% confidence interval (95% CI) 0.86-1.76)). Pooled data from 5 studies on the efficacy of workstation modifications (n = 2,148) showed a statistically significant reduction in the prevalence of shoulder pain with a risk ratio of 1.88 (95% CI 1.20-2.96) compared with different control interventions. Low-grade evidence exists that a workplace exercise programme may reduce the intensity of shoulder pain, and that workstation modifications may reduce the prevalence of shoulder pain.

To investigate the feasibility of rice pads for improving nonuniform fat suppression in magnetic resonance imaging (MRI) of the neck, shoulder, and elbow using the chemical shift selective (CHESS) technique. CHESS imaging of the neck, shoulder, and elbow was performed on 10 healthy volunteers with and without the use of rice pads. Images were visually assessed by one radiologist and one radiologic technologist using a four-point scale. Results were compared using Wilcoxon's signed rank sum test. Images with and without rice pads were rated 3.9 and 1.5 for the neck (P = 0.002), 3.85 and 2.5 for the shoulder (P = 0.002), and 3.4 and 2.45 for the elbow (P = 0.004). Fat-suppressed images obtained using the CHESS technique were significantly improved by rice pads for the neck, shoulder, and elbow, indicating that image deterioration with CHESS caused by magnetic field nonuniformity can be improved by rice pads in all body areas.

Background: The validation of widely used scales facilitates the comparison across international patient samples. Objective: The objective was to translate, culturally adapt and validate the Simple Shoulder Test into Argentinian Spanish. Methods: The Simple Shoulder Test was translated from English into Argentinian Spanish by two independent translators, translated back into English and evaluated for accuracy by an expert committee to correct the possible discrepancies. It was then administered to 50 patients with different shoulder conditions.Psycometric properties were analyzed including internal consistency, measured with Cronbach´s Alpha, test-retest reliability at 15 days with the interclass correlation coefficient. Results: The internal consistency, validation, was an Alpha of 0,808, evaluated as good. The test-retest reliability index as measured by intra-class correlation coefficient (ICC) was 0.835, evaluated as excellent. Conclusion: The Simple Shoulder Test translation and it´s cultural adaptation to Argentinian-Spanish demonstrated adequate internal reliability and validity, ultimately allowing for its use in the comparison with international patient samples.

Steroid injection for shoulder pain causes prolonged increased glucose level in type 1 diabetics

PubMed Central

Povlsen, Bo; Povlsen, Sebastian D

2014-01-01

Shoulder pain is very common in diabetic patients and often treated with steroid injections, with subsequent increases in blood glucose levels or the need for additional insulin being questioned. We report a case of significant and prolonged elevation of blood glucose levels and resultant insulin requirement in a type 1 diabetic man after a single 40 mg injection of triamcinolone for shoulder pain. Within 48 h, the shoulder pain as assessed by a visual analogue scale (0–10) was reduced to zero, but the elevated insulin requirements continued for 4 weeks after the injection. This finding suggests that steroid injections for shoulder pain in diabetics may not always be as safe as previously thought. We propose that medical practitioners advise their patients to monitor their glucose levels more carefully after such injections and that caution is exercised when considering administrating these injections to those who have poorly controlled blood glucose levels preinjection to avoid ketoacidosis.

Neck and shoulder pain is fairly common among adolescents in Korea and results in significant health problem. The aims of this prospective study was to identify the effects of education, in terms of recognition of this issue and posture correction, on prevalence and severity of neck and shoulder pain in Korean adolescents. A prospective, observational cohort design was used. The 912 students from two academic high schools in the city of Seoul were eligible for the current study and 887 completed this study. After a baseline cross-sectional survey, students listened to a lecture about cervical health, focusing on good posture, habits, and stretching exercises to protect the spine, and were encouraged by their teachers to keep the appropriate position. And follow-ups were conducted 3 months later, to evaluate the effect of education. The prevalence of neck and shoulder pain was decreased 19.5% (from 82.5 to 66.4%). The baseline mean usual and worst numeric rating scale were 19.9/100 (95% CI, 18.1-21.7) and 31.2/100 (95% CI, 28.7-33.2), respectively. On the follow-up survey, the mean usual and worst numeric rating scale were decreased significantly by 24.1 and 21.7%, respectively, compared with baseline (P < 0.01). Of the 570 students reporting neck and shoulder pain, 16.4% responded that they had experienced improvement during the 3 months. Education; recognition of this issue and posture correction, for cervical health appeared to be effective in decreasing the prevalence and severity of neck and shoulder pain at a 3 month follow-up.

2017-01-01

Background The windmill pitching motion has been associated with risk for shoulder injury. Since there are no pitching limits on youth fast-pitch softball pitchers, these athletes often pitch multiple games across consecutive days. Strength changes, fatigue levels, and shoulder pain that develop among female fast-pitch pitchers over the course of consecutive days of pitching have not been investigated. Hypothesis Over the course of 2 and 3-day fast-pitch softball tournaments, pitchers will develop progressive objective weakness and increased subjective shoulder fatigue and pain without complete recovery between days. Study Design Cross-Sectional Study. Methods Female fast-pitch softball pitchers between the ages of 14 and 18 who were pitching in 2 and 3-day tournaments were recruited for study participation. At the beginning and end of each day of tournament play, pitchers were asked to quantify shoulder fatigue and shoulder pain levels of their dominant throwing arm using a 10-point visual analog scale (VAS). Shoulder abduction, flexion, external rotation, internal rotation, elbow flexion, and elbow extension strength measurements were gathered using a hand-held dynamometer. Results Over the course of an average single day of tournament participation, pitchers developed significant increases in VAS shoulder fatigue (2.0, 95% CI: 1.3 to 3.0), and pain (1.3, 95% CI: 0.5 to 2.3) and significant strength loss in all tested motions. Pitchers also developed significant increases in VAS shoulder fatigue (3.5, 95% CI: 1.5 to 5.5), VAS shoulder pain (2.5, 95% CI: 1.0 to 4.5) and strength loss in all tested motions over the entire tournament. Shoulder pain, fatigue, and strength do not fully recover between days. The accumulation of subjective shoulder pain and fatigue over the course of tournament play were closely correlated. Conclusion Among youth female fast-pitch softball pitchers, there is a progressive increase in shoulder fatigue, pain, and weakness over the course of 2 and 3-day tournaments without full recovery between consecutive days pitching.

Because there are no pitching limits on youth fast-pitch softball pitchers, these athletes often pitch multiple games across consecutive days. Strength changes, fatigue levels, and shoulder pain that develop among female fast-pitch pitchers over the course of consecutive days of pitching have not been investigated. Over the course of 2- and 3-day fast-pitch softball tournaments, pitchers will develop progressive objective weakness and increased subjective shoulder fatigue and pain without complete recovery between days. Cross-sectional study; Level of evidence, 3. Fourteen female fast-pitch softball pitchers between the ages of 14 and 18 years were evaluated for strength and fatigue changes across 2- and 3-day tournaments. At the beginning and end of each day of tournament play, pitchers were asked to quantify shoulder fatigue and shoulder pain levels of their dominant throwing arm using a 10-point visual analog scale (VAS). Shoulder abduction, flexion, external rotation, internal rotation, elbow flexion, and elbow extension strength measurements were gathered using a handheld dynamometer. Over the course of an average single day of tournament participation, pitchers developed significant increases in VAS scores for shoulder fatigue (median, 2.0; 95% CI, 1.3-3.0) and pain (median, 1.3; 95% CI, 0.5-2.3) and significant strength loss in all tested motions. Pitchers also developed significant increases in VAS shoulder fatigue (median, 3.5; 95% CI, 1.5-5.5), VAS shoulder pain (median, 2.5; 95% CI, 1.0-4.5), and strength loss in all tested motions over the entire tournament. Shoulder pain, fatigue, and strength do not fully recover between days. The accumulation of subjective shoulder pain and fatigue over the course of tournament play were closely correlated. Among youth female fast-pitch softball pitchers, there is a progressive increase in shoulder fatigue, pain, and weakness over the course of 2- and 3-day tournaments without full recovery between consecutive days of pitching.

Treatment of myofascial trigger points in patients with chronic shoulder pain: a randomized, controlled trial

PubMed Central

2011-01-01

Background Shoulder pain is a common musculoskeletal problem that is often chronic or recurrent. Myofascial trigger points (MTrPs) cause shoulder pain and are prevalent in patients with shoulder pain. However, few studies have focused on MTrP therapy. The aim of this study was to assess the effectiveness of multimodal treatment of MTrPs in patients with chronic shoulder pain. Methods A single-assessor, blinded, randomized, controlled trial was conducted. The intervention group received comprehensive treatment once weekly consisting of manual compression of the MTrPs, manual stretching of the muscles and intermittent cold application with stretching. Patients were instructed to perform muscle-stretching and relaxation exercises at home and received ergonomic recommendations and advice to assume and maintain good posture. The control group remained on the waiting list for 3 months. The Disabilities of Arm, Shoulder and Hand (DASH) questionnaire score (primary outcome), Visual Analogue Scale for Pain (VAS-P), Global Perceived Effect (GPE) scale and the number of muscles with MTrPs were assessed at 6 and 12 weeks in the intervention group and compared with those of a control group. Results Compared with the control group, the intervention group showed significant improvement (P < 0.05) on the DASH after 12 weeks (mean difference, 7.7; 95% confidence interval (95% CI), 1.2 to 14.2), on the VAS-P1 for current pain (mean difference, 13.8; 95% CI, 2.6 to 25.0), on the VAS-P2 for pain in the past 7 days (mean difference, 10.2; 95% CI, 0.7 to 19.7) and VAS-P3 most severe pain in the past 7 days (mean difference, 13.8; 95% CI, 0.8 to 28.4). After 12 weeks, 55% of the patients in the intervention group reported improvement (from slightly improved to completely recovered) versus 14% in the control group. The mean number of muscles with active MTrPs decreased in the intervention group compared with the control group (mean difference, 2.7; 95% CI, 1.2 to 4.2). Conclusions The results of this study show that 12-week comprehensive treatment of MTrPs in shoulder muscles reduces the number of muscles with active MTrPs and is effective in reducing symptoms and improving shoulder function in patients with chronic shoulder pain.

Chou, Kee-Lee

2005-09-01

The Shyness Scale (SS) is a brief instrument for assessing shyness as a personality trait. The psychometric properties of the Chinese version of the SS were investigated in a random sample of 192 Macau Chinese older adults. The Chinese version of the SS possesses high internal consistency and exhibited satisfactory short-term test-retest reliability. The Chinese version of the SS exhibited acceptable convergent validity with other negative measures of psychological well-being including negative emotional states (assessed by the Negative Affect Scale), loneliness (assessed by the UCLA Loneliness Scale), and state anxiety and trait anxiety (assessed by STAI). The divergent validity of the Chinese version of the SS was demonstrated by the negative but significant association between the SS and self esteem (assessed by Rosenberg Self Esteem Inventory).

Shoulder pain is disabling and has a considerable socio-economic impact. Over 50% of patients presenting in primary care still have symptoms after 6 months; moreover, prognostic factors such as pain intensity, age, disability level and duration of complaints are associated with poor outcome. Most shoulder complaints in this group are categorized as non-specific. Musculoskeletal ultrasound might be a useful imaging method to detect subgroups of patients with subacromial disorders.This article describes the design of a prospective cohort study evaluating the influence of known prognostic and possible prognostic factors, such as findings from musculoskeletal ultrasound outcome and working alliance, on the recovery of shoulder pain. Also, to assess the usual physiotherapy care for shoulder pain and examine the inter-rater reliability of musculoskeletal ultrasound between radiologists and physiotherapists for patients with shoulder pain. A prospective cohort study including an inter-rater reliability study. Patients presenting in primary care physiotherapy practice with shoulder pain are enrolled. At baseline validated questionnaires are used to measure patient characteristics, disease-specific characteristics and social factors. Physical examination is performed according to the expertise of the physiotherapists. Follow-up measurements will be performed 6, 12 and 26 weeks after inclusion. Primary outcome measure is perceived recovery, measured on a 7-point Likert scale. Logistic regression analysis will be used to evaluate the association between prognostic factors and recovery. The ShoCoDiP (Shoulder Complaints and using Diagnostic ultrasound in Physiotherapy practice) cohort study will provide information on current management of patients with shoulder pain in primary care, provide data to develop a prediction model for shoulder pain in primary care and to evaluate whether musculoskeletal ultrasound can improve prognosis.

One-stage surgical treatment for concomitant rotator cuff tears with shoulder stiffness has comparable results with isolated rotator cuff tears: a systematic review.

Addressing preoperative shoulder stiffness before rotator cuff repair (RCR) is advocated, but the effectiveness of this approach is debatable. We hypothesized that 1-stage treatment of concomitant rotator cuff tear (RCT) with shoulder stiffness has comparable results with isolated RCT. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the databases including MEDLINE, Embase, Cochrane Library, and Scopus were searched using the keywords of "shoulder stiffness" OR "adhesive capsulitis" OR "frozen shoulder" AND "rotator cuff." Studies that met all the criteria compared the 2 arms of isolated RCT vs. RCT with concomitant shoulder stiffness, received no physical therapy before surgery, and reported data of preoperative and postoperative range of motion (ROM) and functional outcomes after surgery. Four level III studies met the inclusion criteria. The non-stiff group (isolated RCT) included 460 patients who underwent RCR; the stiff group (RCT with concomitant shoulder stiffness) included 111 patients who underwent RCR and manipulation under anesthesia with or without capsular release. There were significant differences in preoperative ROM between stiff and non-stiff groups. At final follow-up, there were no statistical differences in all ROM between the 2 groups. There was no significant difference in comparing preoperative and postoperative outcome scores including visual analog scale for pain, Constant, modified American Shoulder and Elbow Surgeons, and University of California-Los Angeles scores. Concomitant surgical treatment of nonmassive RCT and moderate shoulder stiffness in 1 stage may have comparable results to the surgical treatment of RCT in patients without preoperative stiffness. Therefore, a physical therapy regimen before surgical intervention may not be necessary. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

To determine the effects of a brief single component of the graded motor imagery (GMI) sequence (mirror therapy) on active range of motion (AROM), pain, fear avoidance, and pain catastrophization in patients with shoulder pain. Single-blind case series. Three outpatient physical therapy clinics. Patients with shoulder pain and limited AROM (N=69). Patients moved their unaffected shoulder through comfortable AROM in front of a mirror so that it appeared that they were moving their affected shoulder. We measured pain, pain catastrophization, fear avoidance, and AROM in 69 consecutive patients with shoulder pain and limited AROM before and immediately after mirror therapy. There were significant differences in self-reported pain (P=.014), pain catastrophization (P<.001), and the Tampa Scale of Kinesiophobia (P=.012) immediately after mirror therapy; however, the means did not meet or exceed the minimal detectable change (MDC) for each outcome measure. There was a significant increase (mean, 14.5°) in affected shoulder flexion AROM immediately postmirror therapy (P<.001), which exceeded the MDC of 8°. A brief mirror therapy intervention can result in statistically significant improvements in pain, pain catastrophization, fear avoidance, and shoulder flexion AROM in patients presenting with shoulder pain with limited AROM. The immediate changes may allow a quicker transition to multimodal treatment, including manual therapy and exercise in these patients. Further studies, including randomized controlled trials, are needed to investigate these findings and determine longer-term effects. Copyright © 2017 American Congress of Rehabilitation Medicine.

To describe a modified technique for arthroscopic-assisted transfer of the latissimus dorsi tendon in a selected group of patients with irreparable rotator cuff tears and pseudoparalysis and to evaluate its short-term results. Fifteen patients with irreparable rotator cuff tears and pseudoparalysis treated by arthroscopic-assisted latissimus dorsi tendon transfer were included. The mean patient age was 61.53 ± 6.24 years (range, 52-71 years). Patients were assessed with physical examination, University of California Los Angeles (UCLA) Score and Constant-Murley score, as well as visual analog scale score at a mean follow-up of 26.4 ± 2.58 months (range, 24-31 months). At final follow-up, mean UCLA score increased to 27.47 ± 6.31 compared with the preoperative UCLA score of 6.53 ± 2.1 (P < .001). Constant-Murley score was 21 ± 7.41 and 59.73 ± 13.62 (P < .001), visual analog scale pain score was 7.47 ± 1.06 and 2.47 ± 0.91 (P < .001), active forward flexion was 58° ± 21.11° and 130° ± 30.05° (P < .001), active abduction was 51° ± 21.64° and 129.67° ± 25.45° (P < .001), and active external rotation was 13.33° ± 21.68° and 32° ± 18.03° (P < .001) preoperatively and postoperatively, respectively. Mean acromiohumeral distance was 3.13 ± 1.40 mm preoperatively, whereas it was 5.67 ± 1.67 mm postoperatively (P < .001). No significant complications requiring a revision surgery was observed during the final follow-up. The modified technique of arthroscopic-assisted transfer of the latissimus dorsi tendon is a feasible, minimally invasive option for the surgical treatment of irreparable rotator cuff tears in a subset of patients with pseudoparalysis.

Background: The high demands to the glenohumeral joint and the violent shoulder blows experienced during martial arts (MA) could compromise return to sports and increase the recurrence rate after arthroscopic stabilization for anterior shoulder instability in these athletes. Purpose: To report the functional outcomes, return to sports, and recurrences in a series of MA athletes with anterior shoulder instability treated with arthroscopic stabilization with suture anchors. Study Design: Case series; Level of evidence, 4. Methods: A total of 20 consecutive MA athletes were treated for anterior shoulder instability at a single institution between January 2008 and December 2013. Range of motion (ROM), the Rowe score, a visual analog scale (VAS), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Return-to-sport and recurrence rates were also evaluated. Results: The mean age at the time of surgery was 25.4 years (range, 18-35 years), and the mean follow-up was 71 months (range, 36-96 months). No significant difference in preoperative and postoperative shoulder ROM was found. The Rowe, VAS, and ASOSS scores showed statistical improvement after surgery (P < .001). In all, 19 athletes (95%) returned to sports. However, only 60% achieved ≥90% recovery after surgery. The recurrence rate was 20%. Conclusion: In this retrospective study of a consecutive cohort of MA athletes, arthroscopic anterior shoulder stabilization significantly improved functional scores. However, only 60% of the athletes achieved the same level of competition, and there was a 20% recurrence rate. PMID:28932751

Transplant "tourism" typically refers to the practice of traveling outside the country of residence to obtain organ transplantation. This study describes the characteristics and outcomes of 33 kidney transplant recipients who traveled abroad for transplant and returned to University of California, Los Angeles (UCLA) for follow-up. Posttransplantation outcomes were compared between tourists and a matched cohort of patients who underwent transplantation at UCLA (matched for age, race, transplant year, dialysis time, previous transplantation, and donor type). Median follow-up time was 487 d (range 68 to 3056). Compared with all patients who underwent transplantation at UCLA, tourists included more Asians and had shorter dialysis times. Most patients traveled to their region of ethnicity with the majority undergoing transplantation in China (44%), Iran (16%), and the Philippines (13%). Living unrelated transplants were most common. Tourists presented to UCLA a median of 35 d after transplantation. Four patients required urgent hospitalization, three of whom lost their grafts. Seventeen (52%) patients had infections, with nine requiring hospitalization. One patient lost her graft and subsequently died from complications related to donor-contracted hepatitis B. One-year graft survival was 89% for tourists and 98% for the matched UCLA cohort (P = 0.75). The rate of acute rejection at 1 yr was 30% in tourists and 12% in the matched cohort. Tourists had a more complex posttransplantation course with a higher incidence of acute rejection and severe infectious complications.

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) consists of question banks for health domains through computer adaptive testing (CAT). Hypothesis: For patients with glenohumeral arthritis, (1) there would be high correlation between traditional patient-reported outcome (PRO) measures and the PROMIS upper extremity item bank (PROMIS UE) and PROMIS physical function CAT (PROMIS PF CAT), and (2) PROMIS PF CAT would not demonstrate ceiling effects. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Sixty-one patients with glenohumeral osteoarthritis were included. Each patient completed the American Shoulder and Elbow Surgeons (ASES) assessment form, Marx Shoulder Activity Scale, Short Form–36 physical function scale (SF-36 PF), EuroQol 5 Dimensions (EQ-5D) questionnaire, Western Ontario Osteoarthritis Shoulder (WOOS) index, PROMIS PF CAT, and the PROMIS UE. Correlation was defined as high (>0.7), moderate (0.4-0.6), or weak (0.2-0.3). Significant floor and ceiling effects were present if more than 15% of individuals scored the lowest or highest possible total score on any PRO. Results: The PROMIS PF demonstrated excellent correlation with the SF-36 PF (r = 0.81, P < .0001) and good correlation with the ASES (r = 0.62, P < .0001), EQ-5D (r = 0.64, P < .001), and WOOS index (r = 0.51, P < .01). The PROMIS PF demonstrated low correlation with the Marx scale (r = 0.29, P = .02). The PROMIS UE demonstrated good correlation with the ASES (r = 0.55, P < .0001), SF-36 (r = 0.53, P < .01), EQ-5D (r = 0.48, P < .01), and WOOS (r = 0.34, P <.01), and poor correlation with the Marx scale (r = 0.06, P = .62). There were no ceiling or floor effects observed. The mean number of items administered by the PROMIS PRO was 4. Conclusion: These data suggest that for a patient population with operative shoulder osteoarthritis, PROMIS UE and PROMIS PF CAT may be valid alternative PROs. Additionally, PROMIS PF CAT offers a decreased question burden with no ceiling effects. PMID:28944248

Management of massive rotator cuff tears in shoulders without glenohumeral arthritis remains problematic for surgeons. Repairs of massive rotator cuff tears have failure rates of 20% to 94% at 1 to 2 years postoperatively as demonstrated with arthrography, ultrasound, and magnetic resonance imaging. Additionally, inconsistent outcomes have been reported with debridement alone of massive rotator cuff tears, and limitations have been seen with other current methods of operative intervention, including arthroplasty and tendon transfers. The use of interposition porcine acellular dermal matrix xenograft in patients with massive rotator cuff tears will result in improved subjective outcomes, postoperative pain, function, range of motion, and strength. Case series; Level of evidence, 4. Sixty patients (61 shoulders) were prospectively observed for a mean of 50.3 months (range, 24-63 months) after repair of massive rotator cuff tears with porcine acellular dermal matrix xenograft as an interposition graft. Subjective outcome data were obtained with visual analog scale for pain score (0-10, 0 = no pain) and Modified American Shoulder and Elbow Surgeons (MASES) score. Active range of motion in flexion, external rotation, and internal rotation were recorded. Strength in the supraspinatus and infraspinatus muscles was assessed manually on a 10-point scale and by handheld dynamometer. Ultrasound was used to assess the integrity of the repair during latest follow-up. Mean visual analog scale pain score decreased from 4.0 preoperatively to 1.0 postoperatively ( P < .001). Mean active forward flexion improved from 140.7° to 160.4° ( P < .001), external rotation at 0° of abduction from 55.6° to 70.1° ( P = .001), and internal rotation at 90° of abduction from 52.0° to 76.2° ( P < .001). Supraspinatus manual strength increased from 7.7 to 8.8 ( P < .001) and infraspinatus manual strength from 7.7 to 9.3 ( P < .001). Mean dynamometric strength in forward flexion was 77.7 N in nonoperative shoulders (shoulder that did not undergo surgery) and 67.8 N ( P < .001) in operative shoulders (shoulder that underwent rotator cuff repair with interposition porcine dermal matrix xenograft). Mean dynamometric strength in external rotation was 54.5 N in nonoperative shoulders and 50.1 N in operative shoulders ( P = .04). Average postoperative MASES score was 87.8. Musculoskeletal ultrasound showed that 91.8% (56 of 61) of repairs were fully intact; 3.3% (2 of 61), partially intact; and 4.9% (3 of 61), not intact. Patients who underwent repair of massive rotator cuff tears with interposition porcine acellular dermal matrix graft have good subjective function as assessed by the MASES score. Patients have significant improvement in pain, range of motion, and manual muscle strength. Postoperative ultrasound demonstrated that the repair was completely intact in 91.8% of patients, a vast improvement compared with results previously reported for primary repairs of massive rotator cuff tears.

In upper brachial plexus palsy patients, loss of shoulder function and elbow flexion is obvious as the result of paralysed muscles innervated by the suprascapular, axillary and musculocutaneus nerve. Shoulder stabilisation, restoration of abduction and external rotation are important as more distal functions will be affected by the shoulder situation. Between 2005 and 2011, eleven patients with upper type brachial plexus palsy were operated on with triceps nerve branch transfer to anterior axillary nerve branch and spinal accessory nerve transfer to the suprascapular nerve for shoulder abduction and external rotation restoration. Nine patients met the inclusion criteria for the study. All patients were men with ages ranged from 21 to 35 years (average, 27.4 years). The interval between injury and surgery ranged from 4 to 11 months (average, 7.2 months). Atrophy of the supraspinatus, infraspinatus and deltoid muscle and subluxation at the glenohumeral joint was obvious in all patients preoperatively. During the pre-op examination all patients had at least muscle grading 4 on the triceps muscle. The mean post-operative value of shoulder abduction was 112.2° (range: 60-170°) while preoperatively none of the patients was able for abduction (p<0.001). The mean post-operative value of shoulder external rotation was 66° (range: 35-110°) while preoperatively none of them was able for external rotation (p<0.001). Postoperative values of shoulder abduction were significantly better that those of external rotation (p=0.0004). The postoperative average muscle grading for shoulder abduction according the MRC scale was 3.6±0.5 and for the shoulder external rotation was 3.2±0.4. Combined nerve transfer by using the spinal accessory nerve for suprascapular nerve neurotisation and one of the triceps nerve branches for axillary nerve and teres minor branch neurotisation is an excellent choice for shoulder abduction and external rotation restoration.

To find intra rater and inter rater reliability of Dynamic Rotator Stability Test (DRST) and to find concurrent validity of Dynamic Rotator Stability Test (DRST) with University of Pennsylvania Shoulder Score (PENN) Scale. 40 subjects of either gender between the age group of 18-70 with painful shoulder conditions of musculoskeletal origin was selected through convenient sampling. Tester 1 and tester 2 administered DRST and PENN scale randomly. In a subgroup of 20 subjects DRST was administered by both the testers to find the inter rater reliability. 180° Standard Universal Goniometer was used to take measurements. For intra-rater reliability, all the test variables were showing highly significant correlation (p=.94 - 1). For inter -rater, with tester 2, test variables like position, ROM, force, direction of abnormal translation, pain during the test, compensatory movement during test were found to be significant (p=.71-1).only some variables of DRST showed significant correlation with PENN scale (P=.320-.450). Dynamic Rotator Stability Test has good intra rater and moderate inter rater reliability. Concurrent validity of Dynamic Rotator Stability Test was found to be poor when compared to PENN Shoulder Score.

Summary Introduction. Work-related Musculoskeletal Disorders (WMSDs) can impact on fatigue and productivity of office workers. This study aimed to investigate the effect of musculoskeletal problems on fatigue and productivity among office personnel. Methods. This study was performed on 101 Iranian office workers. Data were gathered through a demographic questionnaire, Nordic Musculoskeletal Questionnaire, Numeric Rating Scale, Persian version of Multidimensional Assessment of Fatigue Scale, and Persian version of Health and Work Questionnaire. Results. The results revealed that the highest prevalence rates of musculoskeletal symptoms in the past week were related to neck (41.6%), lower back (41.6%), and shoulders (40.6%). The mean score of discomfort/pain was 1.67, 1.55, and 1.31 in the neck, lower back, and shoulders, respectively. Additionally, the severity of discomfort/pain in neck, shoulders, lower back, and thighs was correlated to total fatigue. The severity of discomfort/pain in neck, lower back, buttock, and thighs was also correlated to the concentration/focus subscale of productivity. Conclusions. Improvement of working conditions is suggested to reduce musculoskeletal problems and fatigue and enhance productivity. PMID:29123372

We developed a Korean version of the disabilities of arm, shoulder, and hand outcome questionnaire (K-DASH) by performing cross-cultural adaptation and evaluated the reliability and validity of the K-DASH. The K-DASH, SF-36, and Visual Analog Scale (VAS) for pain were administered to 161 patients with arm, shoulder, and hand problems. The internal consistency of the disability/symptom scores of the K-DASH was high (Cronbach's alpha 0.94). The retest assessed 131 of the 161 patients. The intraclass correlation coefficient was 0.91. The construct validity was evaluated using the correlations between the K-DASH and the SF-36 and VAS. The physical and mental component summary scales of the SF-36 and the VAS at rest and during activity were significantly correlated with the DASH disability/symptom scores. Despite the linguistic and cultural differences, the reliability and validity of the K-DASH were just as excellent as those of the original DASH.

Responsiveness of the numeric pain rating scale in patients with shoulder pain and the effect of surgical status.

PubMed

Michener, Lori A; Snyder, Alison R; Leggin, Brian G

2011-02-01

The Numeric Pain Rating Scale (NPRS) is commonly used to assess pain. Change in the NPRS across time can be interpreted with responsiveness indices. To determine the minimal clinically important difference (MCID) of the NPRS. Single-group repeated measures. Outpatient rehabilitation clinics. Patients with shoulder pain (N = 136). At the initial evaluation patients completed the Penn Shoulder Score (PSS), which includes pain, satisfaction, and function sections. Pain was measured using an 11-point NPRS for 3 conditions of pain: at rest, with normal daily activities, and with strenuous activities. The NPRS average was calculated by averaging the NPRS scores for 3 conditions of pain. The final PSS was completed after 3-4 wk of rehabilitation. To determine the MCID for the NPRS average, the minimal detectible change of 8.6 points for the PSS function scale (0-60 points) was used as an external criterion anchor to classify patients as meaningfully improved (≥8.6 point change) or not improved (<8.6-point change). The MCID for the NPRS average was also determined for subgroups of surgical and nonsurgical patients. Cohen's effect sizes were calculated as a measure of group responsiveness for the NPRS average. Using a receiver-operating-characteristic analysis, the MCID for the average NPRS for all patients was 2.17, and it was 2.17 for both the surgical and nonsurgical subgroup: area-under-the-curve range .74-.76 (95%CI: .55-.95). The effect size for all patients was 1.84, and it was 1.51 and 1.94 for the surgical and nonsurgical groups, respectively. The NPRS average of 3 pain questions demonstrated responsiveness with an MCID of 2.17 in patients with shoulder pain receiving rehabilitation for 3-4 wk. The effect sizes indicated a large effect. However, responsiveness values are not static. Further research is indicated to assess responsiveness of the NPRS average in different types of patients with shoulder pain.

To compare the clinical efficacy in the treatment of post-stroke shoulder-hand syndrome between floating-needle therapy and conventional acupuncture on the basis of rehabilitation training. One hundred cases of post-stroke shoulder-hand syndrome were randomized into a floating-needle group and an acupuncture group, 50 cases in each one. The passive and positive rehabilitation training was adopted in the two groups. Additionally, in the floating-needle group, the floating-needle therapy was used. The needle was inserted at the site 5 to 10 cm away from myofasical trigger point (MTrP), manipulated and scattered subcutaneously, for 2 min continuously. In the acupuncture group, the conventional acupuncture was applied at Jianqian (EX-UE), Jianyu (LI 15), Jianliao (TE 14), etc. The treatment was given once every two days, 3 times a week, and 14 days of treatment were required. The shoulder hand syndrome scale (SHSS), the short form McGill pain scale (SF-MPQ) and the modified Fugl-Meyer motor function scale (FMA) were used to evaluate the damage severity, pain and motor function of the upper limbs before and after treatment in the two groups. The clinical efficacy was compared between the two groups. SHSS score, SF-MPQ score and FMA score were improved significantly after treatment in the two groups (all P < 0.01), and the improvements in the floating-needle group were superior to those in the acupuncture group (all P < 0.05). The total effective rate was 94.0% (47/50) in the floating-needle group, which was better than 90.0% (45/50) in the acupuncture group (P < 0.05). The floating-needle therapy combined with rehabilitation training achieves a satisfactory efficacy on post-stroke shoulder-hand syndrome, which is better than the combined therapy of conventional acupuncture and rehabilitation training.

Background Many patients suffer from severe shoulder complaints after breast cancer surgery and axillary lymph node dissection. Physiotherapy has been clinically observed to improve treatment of these patients. However, it is not a standard treatment regime. The purpose of this study is to investigate the efficacy of physiotherapy treatment of shoulder function, pain and quality of life in patients who have undergone breast cancer surgery and axillary lymph node dissection. Methods Thirty patients following breast cancer surgery and axillary lymph node dissection were included in a randomised controlled study. Assessments were made at baseline and after three and six months. The treatment group received standardised physiotherapy treatment of advice and exercises for the arm and shoulder for three months; the control group received a leaflet containing advice and exercises. If necessary soft tissue massage to the surgical scar was applied. Primary outcome variables were amount of pain in the shoulder/arm recorded on the Visual Analogue Scale, and shoulder mobility (flexion, abduction) measured using a digital inclinometer under standardized conditions. Secondary outcome measures were shoulder disabilities during daily activities, edema, grip strength of both hands and quality of life. The researcher was blinded to treatment allocation. Results All thirty patients completed the trial. After three and six months the treatment group showed a significant improvement in shoulder mobility and had significantly less pain than the control group. Quality of life improved significantly, however, handgrip strength and arm volume did not alter significantly. Conclusion Physiotherapy reduces pain and improves shoulder function and quality of life following axillary dissection after breast cancer. Trial registration ISRCTN31186536 PMID:17760981

To determine the efficacy of Anma massage therapy for patients with Parkinson's disease (PD) in geriatric health services facilities. (1) Immediate treatment effects: 10 PD patients, in the intervention period with Hoehn and Yahr (H&Y) scale at stage 5, received 30-40 min sessions of Anma massage therapy. In the non-intervention period, six PD patients did not undergo this therapy. The shoulder joint range of motion (ROM) was measured before and after each session. (2) Continuous treatment effects: Six PD patients in the intervention period received the same massage sessions once a week continuously for seven weeks. One week after the completion of the treatment, the ROM of the shoulder joints was measured. (1) Shoulder abduction on the more affected side showed immediate significant improvements. (2) Shoulder abduction on the more affected side and less affected side showed notable effects of continuous treatment procedure leading to significant improvement. The above results suggested the efficacy of successive Anma massage therapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

Erosion, transportation and the nature of the Maria

Lunar Orbiter and Apollo photographs of the moon and laboratory simulations of a surface transportation mechanism are discussed. Studies of shoulders at junctions of old mountains with flat mare surfaces show that the crater density in the shoulder is lower than that in the neighboring ground. The crisscross pattern is very pronounced on the mountain slope, is on the shoulder in a smaller scale, and is absent on the mare surface. It is concluded that the material forming the shoulders came there as a consequence of a surface transportation mechanism, and that the shoulders reached their present configuration later than the final shaping of the mare surface. Seismic signal transmission and mascon distribution data indicate that the filling of mare basins did not occur in a similar manner. An electrostatic mechanism for surface transportation was studied experimentally by bombarding material with electrons. An electric field resulted which was capable of dislodging and moving grains. It was also found that the junction line between different materials remains sharp, and materials do not mix even when the junction line itself moves.

To compare the efficacy difference in the treatment of shoulder pain in post-stroke shoulder-hand syndrome among floating acupuncture, oral administration of western medicine and local fumigation of Chinese herbs. Ninety cases of post-stroke shoulder-hand syndrome (stage I) were randomized into a floating acupuncture group, a western medicine group and a local Chinese herbs fumigation group, 30 cases in each one. In the floating acupuncture group, two obvious tender points were detected on the shoulder and the site 80-100 mm inferior to each tender point was taken as the inserting point and stimulated with floating needling technique. In the western medicine group, mobic 7.5 mg was prescribed for oral administration. In the local Chinese herbs fumigation group, the formula for activating blood circulation and relaxing tendon was used for local fumigation. All the patients in three groups received rehabilitation training. The floating acupuncture, oral administration of western medicine, local Chinese herbs fumigation and rehabilitation training were given once a day respectively in corresponding group and the cases were observed for 1 month. The visual analogue scale (VAS) and Takagishi shoulder joint function assessment were adopted to evaluate the dynamic change of the patients with shoulder pain before and after treatment in three groups. The modified Barthel index was used to evaluate the dynamic change of daily life activity of the patients in three groups. With floating acupuncture, shoulder pain was relieved and the daily life activity was improved in the patients with post-stroke shoulder-hand syndrome, which was superior to the oral administration of western medicine and local Chinese herbs fumigation (P < 0.01). With local Chinese herbs fumigation, the improvement of shoulder pain was superior to the oral administration of western medicine. The difference in the improvement of daily life activity was not significant statistically between the local Chinese herbs fumigation and oral administration of western medicine, the efficacy was similar between these two therapies (P > 0.05). The floating acupuncture relieves shoulder pain of the patients with post-stroke shoulder-hand syndrome promptly and effectively, and the effects on shoulder pain and the improvements of daily life activity are superior to that of the oral administration of western medicine and local Chinese herbs fumigation.

The aims of the study were to assess the overall reduction of pain in patients undergoing ultrasound-guided shoulder injections and to characterize the preinjection point-of-care ultrasound findings and use of clinical services postinjection including the use of magnetic resonance imaging and surgeries. Data of 172 patients who underwent ultrasound-guided subacromial subdeltoid injection or glenohumeral joint injection were reviewed for preinjection point-of-care ultrasound findings, change in pain intensity at 2 mos from baseline, and use of care at 6 mos' postinjection. Pain intensity was measured by the numeric rating scale and a dichotomous report of global impression of significant improvement in pain. Responders were defined as those with 50% or more reduction in numeric rating scale or those with global impression of 50% or more improvement. There were 141 responders among the 172 patients analyzed. Full-thickness rotator cuff tears were higher in the ultrasound-guided subacromial subdeltoid injection group when compared with the glenohumeral joint injection group (P = 0.038) and abnormal bicipital tendon findings higher in the glenohumeral joint injection group (P = 0.016). There were no significant differences in specific abnormal U findings between responders versus nonresponders. Twelve patients had a shoulder magnetic resonance imaging and four patients underwent operative interventions after the injection. Overall pain reduction after ultrasound-guided shoulder injections was favorable in the short term. There was no specific preinjection point-of-care ultrasound findings associated with clinical pain reduction after injection. Additional imaging and operative intervention after ultrasound-guided shoulder injections seemed to be relatively low.

[Relationship between four components of assertiveness and mental health among high school students].

PubMed

Watanabe, Asami

2009-04-01

This study examines the relationship between four components of assertiveness ("open expression", "control of emotion", "consideration for others" and "self-direction") and mental health. In Study 1, the analysis of interviews with thirteen high school students suggested that some components did not have a positive relationship with mental health. In Study 2, 176 high school students completed a questionnaire which included the UCLA isolation scale, the General Health Questionnaire (GHQ) and a scale to measure the four components of assertiveness. The results showed that an excessively high score for "consideration for others" was associated with mental unhealthiness. This component probably has an optimum level to maintain mental health.

Shoulder pain and loss of function are directly associated with obesity. We hypothesized that significant interactions would exist between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) and obesity status on functional and quality of life (QOL) outcomes over the long term. Clinical and QOL outcomes (American Shoulder and Elbow Surgeons Evaluation form, Shoulder Pain and Disability Index, University of California at Los Angeles Shoulder Rating scale, Medical Outcomes Short Form 12 (SF-12), range of motion (ROM), and strength) were longitudinally compared in patients with low and high body mass index (BMI) after a TSA or a RSA. Prospectively collected data of patients with a TSA or RSA were reviewed (N = 310). Preoperative, 2-year, and final follow-up visits were included (range 3-17 years; mean 5.0 ± 2.5 years). Patient data were stratified for analysis using BMI. Morbidly obese patients had worse preoperative functional scores and QOL compared to the other groups. There were no significant interactions of BMI group by surgery type for any of the outcome variables except for active external rotation ROM. Morbidly obese patients attained lower SF-12 scores compared to the remaining groups at each time point. Both TSA and RSA can be expected to impart positive functional outcomes in patients irrespective of BMI. Morbidly obese patients do not attain the same gains in Medical Outcomes SF-12 scores as the non-morbidly obese patients. The lower improvements in active external ROM may be due to morphological limitations of excessive adiposity. This is a level II study.

Periarthritis (PA) shoulder characterised by pain and restricted range of motion has a plethora of treatment options with inconclusive evidence. Platelet Rich Plasma (PRP) is an emerging treatment option and its efficacy needs to be examined and compared with other routine interventions. To assess the efficacy of PRP injection and compare it with corticosteroid injection and ultrasonic therapy in the treatment of PA shoulder. Patients with PA shoulder (n=195) were randomised to receive single injection of PRP (2 ml) or corticosteroid (80 mg of methylprednisolone) or ultrasonic therapy (seven sittings in two weeks; 1.5 W/cm 2 , 1 MHz, continuous mode). All participants were also advised to perform a home based 10 minute exercise therapy. The primary outcome measure was active range of motion of the shoulder. Secondary outcome measures used were Visual Analogue Scale (VAS) for pain and a shortened version of Disabilities of the Arm, Shoulder and Hand (QuickDASH) for function. Participants were evaluated at 0, 3, 6 and 12 weeks. Chi-square test, one way and repeated measures of ANOVA tests were used to determine significant differences. PRP treatment resulted in statistically significant improvements over corticosteroid and ultrasonic therapy in active as well as passive range of motion of shoulder, VAS and QuickDASH at 12 weeks. At six weeks, PRP treatment resulted in statistically significant improvements over ultrasonic therapy in VAS and QuickDASH. No major adverse effects were observed. This study demonstrates that single injection of PRP is effective and better than corticosteroid injection or ultrasonic therapy in treatment of PA shoulder.

Diaphragm-Sparing Nerve Blocks for Shoulder Surgery.

PubMed

Tran, De Q H; Elgueta, Maria Francisca; Aliste, Julian; Finlayson, Roderick J

Shoulder surgery can result in significant postoperative pain. Interscalene brachial plexus blocks (ISBs) constitute the current criterion standard for analgesia but may be contraindicated in patients with pulmonary pathology due to the inherent risk of phrenic nerve block and symptomatic hemidiaphragmatic paralysis. Although ultrasound-guided ISB with small volumes (5 mL), dilute local anesthetic (LA) concentrations, and LA injection 4 mm lateral to the brachial plexus have been shown to reduce the risk of phrenic nerve block, no single intervention can decrease its incidence below 20%. Ultrasound-guided supraclavicular blocks with LA injection posterolateral to the brachial plexus may anesthetize the shoulder without incidental diaphragmatic dysfunction, but further confirmatory trials are required. Ultrasound-guided C7 root blocks also seem to offer an attractive, diaphragm-sparing alternative to ISB. However, additional large-scale studies are needed to confirm their efficacy and to quantify the risk of periforaminal vascular breach. Combined axillary-suprascapular nerve blocks may provide adequate postoperative analgesia for minor shoulder surgery but do not compare favorably to ISB for major surgical procedures. One intriguing solution lies in the combined use of infraclavicular brachial plexus blocks and suprascapular nerve blocks. Theoretically, the infraclavicular approach targets the posterior and lateral cords, thus anesthetizing the axillary nerve (which supplies the anterior and posterior shoulder joint), as well as the subscapular and lateral pectoral nerves (both of which supply the anterior shoulder joint), whereas the suprascapular nerve block anesthetizes the posterior shoulder. Future randomized trials are required to validate the efficacy of combined infraclavicular-suprascapular blocks for shoulder surgery.

A National Science Foundation Graduate Teaching Fellows in K- 12 Education program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/ ) partners UCLA faculty and graduate students (fellows) with urban middle and high school science teachers and their students to foster programs of science and engineering exploration that bring the environment of Los Angeles into the classroom. UCLA science and engineering graduate fellows serve as scientists-in-residence at four partner schools to integrate inquiry-based science lessons, facilitate advancements in science content teaching, and ultimately, to improve their own science communication skills. As part of their fellowship, graduate students are required to develop three "major" lessons, including one based on their PhD research at UCLA. During the first four years of the project, the SEE-LA fellows have developed a range of research-based activities, including lessons on sustainable fisheries, ecosystems and remote sensing, earthquakes, urban water quality including invertebrate observations, and post-fire soil chemistry, among others. This presentation will provide an overview of the SEE-LA GK-12 program and development of research lessons that also address California State Science Standards. We also discuss potential sustainability of GK-12 type outreach and education programs. The SEE-LA program has provided development of graduate student communication and teaching skills while also contributing significantly to the integration of science education into K-12 curriculum in Los Angeles schools.

Background and objectives: Transplant “tourism” typically refers to the practice of traveling outside the country of residence to obtain organ transplantation. This study describes the characteristics and outcomes of 33 kidney transplant recipients who traveled abroad for transplant and returned to University of California, Los Angeles (UCLA) for follow-up. Design, settings, participants, & measurements: Posttransplantation outcomes were compared between tourists and a matched cohort of patients who underwent transplantation at UCLA (matched for age, race, transplant year, dialysis time, previous transplantation, and donor type). Median follow-up time was 487 d (range 68 to 3056). Results: Compared with all patients who underwent transplantation at UCLA, tourists included more Asians and had shorter dialysis times. Most patients traveled to their region of ethnicity with the majority undergoing transplantation in China (44%), Iran (16%), and the Philippines (13%). Living unrelated transplants were most common. Tourists presented to UCLA a median of 35 d after transplantation. Four patients required urgent hospitalization, three of whom lost their grafts. Seventeen (52%) patients had infections, with nine requiring hospitalization. One patient lost her graft and subsequently died from complications related to donor-contracted hepatitis B. One-year graft survival was 89% for tourists and 98% for the matched UCLA cohort (P = 0.75). The rate of acute rejection at 1 yr was 30% in tourists and 12% in the matched cohort. Conclusions: Tourists had a more complex posttransplantation course with a higher incidence of acute rejection and severe infectious complications. PMID:18922987

Home care workers are at risk of various harmful occupational exposures, health complaints and sick leave. Identifying occupational exposures related to shoulder-neck and low back pain, and assessing the comparative importance of such exposures, for home care workers. One hundred and thirty-eight home care workers in a large municipality in Norway participated in the study (response rate 76.2%). Questionnaire comprised a combination of standardized items and context-specific VAS scales on mental, social, emotional and physical work demands, perceived general tension and pain in shoulder-neck and low back. Severe pain scores for both shoulder-neck and low back regions were common, with individual variations. All VAS measures on occupational exposures were significantly correlated with shoulder-neck pain and all except social demands were significantly correlated with low back pain. However, stronger associations were found with perceived general tension, which proved to be the strongest predictor of shoulder-neck and low back pain, indicating a mediating effect in the relationship between occupational exposures and musculoskeletal pain. Identifying and alleviating occupational exposures is important to ensure a healthy and sustainable work environment. Special attention should be drawn to early signs of symptoms, such as general tension, preventing further development of musculoskeletal pain.

The purpose of this study was to document the diagnosis, surgical treatment, and functional outcome in patients with subscapularis ruptures after shoulder arthroplasty. Prospective objective and subjective data were collected on 7 patients with symptomatic rupture of the subscapularis tendon after shoulder arthroplasty. Presenting signs and symptoms included pain, weakness in internal rotation, increased external rotation, and anterior instability. All patients were treated with surgical repair of the ruptured tendon. Four required repair augmentation with a transfer of the pectoralis major tendon. After subscapularis repair and pectoralis transfer, 2 patients continued to have anterior instability and required an additional operation to address the instability. At a mean follow-up of 2.3 years (range, 18-55 months), the mean American Shoulder and Elbow Surgeons shoulder score in this study group was 63.2. The mean patient satisfaction rating, on a 10-point scale, was 6.2. Factors associated with post-arthroplasty subscapularis ruptures included subscapularis lengthening techniques used to address internal rotation contracture and previous surgery that violated the subscapularis tendon. Symptomatic subscapularis rupture after shoulder arthroplasty introduces the need for additional surgery and a period of protected or delayed rehabilitation after arthroplasty. Although symptoms were adequately addressed with appropriate surgical treatment, decreased functional outcomes were observed.

Nontraumatic full-thickness rotator cuff tears are commonly initially treated conservatively. If conservative treatment fails, rotator cuff repair is a viable subsequent option. The objective of the present meta-analysis is to evaluate the shoulder-specific outcomes one year after arthroscopic or mini-open rotator cuff repair of nontraumatic rotator cuff tears. A literature search was conducted in PubMed and EMBASE within the period January 2000 to January 2017. All studies measuring the clinical outcome at 12 months after nontraumatic rotator cuff repair of full-thickness rotator cuff tears were listed. We included 16 randomized controlled trials that met our inclusion criteria with a total of 1.221 shoulders. At 12 months after rotator cuff repair, the mean Constant score had increased 29.5 points; the mean American Shoulder and Elbow Score score increased by 38.6 points; mean Simple Shoulder Test score was 5.6 points; mean University of California Los Angeles score improved by 13.0 points; and finally, mean Visual Analogue Scale score decreased by 4.1 points. Based on this meta-analysis, significant improvements in the shoulder-specific indices are observed 12 months after nontraumatic arthroscopic or mini-open rotator cuff repair.

Compensating for intersegmental dynamics across the shoulder, elbow, and wrist joints during feedforward and feedback control.

Maeda, Rodrigo S; Cluff, Tyler; Gribble, Paul L; Pruszynski, J Andrew

2017-10-01

Moving the arm is complicated by mechanical interactions that arise between limb segments. Such intersegmental dynamics cause torques applied at one joint to produce movement at multiple joints, and in turn, the only way to create single joint movement is by applying torques at multiple joints. We investigated whether the nervous system accounts for intersegmental limb dynamics across the shoulder, elbow, and wrist joints during self-initiated planar reaching and when countering external mechanical perturbations. Our first experiment tested whether the timing and amplitude of shoulder muscle activity account for interaction torques produced during single-joint elbow movements from different elbow initial orientations and over a range of movement speeds. We found that shoulder muscle activity reliably preceded movement onset and elbow agonist activity, and was scaled to compensate for the magnitude of interaction torques arising because of forearm rotation. Our second experiment tested whether elbow muscles compensate for interaction torques introduced by single-joint wrist movements. We found that elbow muscle activity preceded movement onset and wrist agonist muscle activity, and thus the nervous system predicted interaction torques arising because of hand rotation. Our third and fourth experiments tested whether shoulder muscles compensate for interaction torques introduced by different hand orientations during self-initiated elbow movements and to counter mechanical perturbations that caused pure elbow motion. We found that the nervous system predicted the amplitude and direction of interaction torques, appropriately scaling the amplitude of shoulder muscle activity during self-initiated elbow movements and rapid feedback control. Taken together, our results demonstrate that the nervous system robustly accounts for intersegmental dynamics and that the process is similar across the proximal to distal musculature of the arm as well as between feedforward (i.e., self-initiated) and feedback (i.e., reflexive) control. NEW & NOTEWORTHY Intersegmental dynamics complicate the mapping between applied joint torques and the resulting joint motions. We provide evidence that the nervous system robustly predicts these intersegmental limb dynamics across the shoulder, elbow, and wrist joints during reaching and when countering external perturbations.

The extratropical 40-day oscillation in the UCLA general circulation model. Part 1: Atmospheric angular momentum

NASA Technical Reports Server (NTRS)

Marcus, S. L.; Ghil, M.; Dickey, J. O.

1994-01-01

Variations in atmospheric angular momentum (AAM) are examined in a three-year simulation of the large-scale atmosphere with perpetual January forcing. The simulation is performed with a version of the University of California at Los Angeles (UCLA) general circulation model that contains no tropical Madden-Julian Oscillation (MJO). In addition, the results of three shorter experiments with no topography are analyzed. The three-year standard topography run contains no significant intraseasonal AAM periodicity in the tropics, consistent with the lack of the MJO, but produces a robust, 42-day AAM oscillation in the Northern Hemisphere (NH) extratropics. The model tropics undergoes a barotropic, zonally symmetric oscillation, driven by an exchange of mass with the NH extratropics. No intraseasonal periodicity is found in the average tropical latent heating field, indicating that the model oscillation is dynamically rather than thermodynamically driven. The no-mountain runs fail to produce an intraseasonal AAM oscillation, consistent with a topographic origin for the NH extratropical oscillation in the standard model. The spatial patterns of the oscillation in the 500-mb height field, and the relationship of the extratropical oscillation to intraseasonal variations in the tropics, will be discussed in Part 2 of this study.

The objective of this study was to evaluate the psychometric properties of the Constant-Murley Score (CMS) in various shoulder pathologies, based on a systematic review and expert standardized evaluations. A systematic review was performed in MEDLINE and EMBASE databases. Titles and abstracts were reviewed and finally the included articles were grouped according to patients' pathologies. Two expert evaluators independently assessed the CMS properties of reliability, validity, responsiveness to change, interpretability and burden score in each group, using the EMPRO (Evaluating Measures of Patient Reported Outcomes) tool. The CMS properties were assessed per attribute and overall for each considered group. Only the concept and measurement model was assessed globally. Five individual pathologies (i.e. subacromial, fractures, arthritis, instability and frozen shoulder) and two additional groups (i.e. various pathologies and healthy subjects) were considered. Overall EMPRO scores ranged from 58.6 for subacromial to 30.6 points for instability. Responsiveness to change was the only quality to obtain at least 50 points across all groups, but for frozen shoulder. Insufficient information was obtained in relation to the concept and measurement model and great variability was seen in the other evaluated attributes. The current evidence does not support the CMS as a gold standard in shoulder evaluation. Its use is advisable for subacromial pathology; but data are inconclusive for other shoulder conditions. Prospective studies exploring the psychometric properties of the scale, particularly for fractures, arthritis, instability and frozen shoulder are needed. Systematic review.

Shoulder surgery can produce severe postoperative pain and movement limitations. Evidence has shown that regional nerve block is an effective management for postoperative shoulder pain. The purpose of this study was to investigate the postoperative analgesic effect of intravenous patient-controlled analgesia (PCA) combined with interscalene nerve block in comparison to PCA alone after shoulder surgery. In this study, 103 patients receiving PCA combined with interscalene nerve block (PCAIB) and 48 patients receiving PCA alone after shoulder surgery were included. Patients' characteristics, preoperative shoulder score and range of motion, surgical and anesthetic condition in addition to visual analog scale (VAS) pain score, postoperative PCA consumption, and adverse outcomes were evaluated. The results showed that PCA combined with interscalene nerve block (PCAIB) group required less volume of analgesics than PCA alone group in 24 hours (57.76 ± 23.29 mL versus 87.29 ± 33.73 mL, p < 0.001) and 48 hours (114.86 ± 40.97 mL versus 183.63 ± 44.83 mL, p < 0.001) postoperatively. The incidence of dizziness in PCAIB group was significantly lower than PCA group (resp., 1.9% and 14.6%, p = 0.005). VAS, nausea, and vomiting were less in group PCAIB, but in the absence of significant statistical correlation. Interscalene nerve block is effective postoperatively in reducing the demand for PCA analgesics and decreasing opioids-induced adverse events following shoulder surgery.

Inclusion criteria were patients with glenoid bone loss (GBL) ranging from 5% to 25%, anterior capsular deficiency, and Hill-Sachs lesion who underwent ASA technique. Exclusion criteria were GBL >25%, multidirectional instability, preexisting osteoarthritis, and overhead sports activities. Visual analog scale (VAS) scale for pain, Rowe score, and American Shoulder and Elbow Surgeons (ASES) scores were used to assess results. Loss of shoulder external rotation was measured with the arm at the side (ER1 position) or 90° in abduction (ER2 position). Analysis of variance and Fisher tests were used for data evaluation. Significance was established at P ≤ .05. One hundred ten patients (84 men and 26 women, mean age 27 years) were evaluated with a mean follow-up of 40.5 months (range: 24 to 65 months). In 98 patients, a Hill-Sachs lesion was observed and in 57 patients a capsular deficiency was present. Three patients (2.7%) had a traumatic redislocation. At final follow-up, the mean scores were as follows: VAS scale decreased from a mean of 3.5 to 0.5 (P = .015), Rowe score increased from 57.4 to 95.3 (P = .035), and ASES score increased from 66.5 to 96.5 (P = .021). The mean deficit of external rotation was 8° ± 2.5° in the ER1 position and 4° ± 1.5° in the ER2 position. The ASA procedure has been shown to be effective in restoring joint stability in patients practicing sports, affected by chronic anterior shoulder instability associated with anterior GBL (<25%), capsular deficiency, and Hill-Sachs lesions, with mild restriction of external rotation.

Gombosi, Tamas I.

The University of Michigan participated in the joint UCLA/Maryland fusion science center focused on plasma physics problems for which the traditional separation of the dynamics into microscale and macroscale processes breaks down. These processes involve large scale flows and magnetic fields tightly coupled to the small scale, kinetic dynamics of turbulence, particle acceleration and energy cascade. The interaction between these vastly disparate scales controls the evolution of the system. The enormous range of temporal and spatial scales associated with these problems renders direct simulation intractable even in computations that use the largest existing parallel computers. Our efforts focused on twomore » main problems: the development of Hall MHD solvers on solution adaptive grids and the development of solution adaptive grids using generalized coordinates so that the proper geometry of inertial confinement can be taken into account and efficient refinement strategies can be obtained.« less

Acromioplasty is commonly performed during arthroscopic rotator cuff repair, but its effect on short-term outcomes is debated. To report the short-term clinical outcomes of patients undergoing arthroscopic repair of full-thickness rotator cuff tears with and without acromioplasty. Randomized controlled trial; Level of evidence, 2. Patients undergoing arthroscopic repair of full-thickness rotator cuff tears were randomized into acromioplasty or nonacromioplasty groups. The Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) score, Constant score, University of California-Los Angeles (UCLA) score, and Short Form-12 (SF-12) health assessment were collected along with physical examination including range of motion and dynamometer strength testing. Intraoperative data including tear size, repair configuration, and concomitant procedures were recorded. Follow-up examination was performed at regular intervals up to 2 years. Preoperative imaging was reviewed to classify the acromial morphologic type, acromial angle, and lateral acromial angulation. A total of 114 patients were initially enrolled in the study, and 95 (83%; 43 nonacromioplasty, 52 acromioplasty) were available for a minimum 2-year follow-up. There were no significant differences in baseline characteristics, including number of tendons torn, repair configuration, concomitant procedures, and acromion type and angles. Within groups, there was a significant (P < .001) improvement in all functional outcome scores from preoperatively to all follow-up time points, including 2 years, for the nonacromioplasty and acromioplasty groups (ASES score: 55.1-91.5, 48.8-89.0; Constant score: 48.3-75.0, 51.9-78.7, respectively). There were no significant differences in functional outcomes between nonacromioplasty and acromioplasty groups or between subjects with different acromial features at any time point. The results of this study demonstrate no difference in clinical outcomes after rotator cuff repair with or without acromioplasty at 2 years postoperatively. © 2014 The Author(s).

The purpose of this study was to determine: 1) the test-retest reliability of Fear-Avoidance Beliefs Questionnaire (FABQ) Work (FABQW) subscale, FABQ Physical Activity (FABQPA) subscale, Shoulder Pain and Disability Index (SPADI) Pain subscale, SPADI Disability subscale, and Numeric Pain Rating scale (NPRS); and 2) the relationship between the FABQPA, FABQW, SPADI pain, SPADI disability, and NPRS after 4 weeks of pragmatically applied physical therapy (PT) in patients with shoulder pain. Prospective, single-group observational design. Data were collected at initial evaluation, the first follow-up visit prior to the initiation of treatment, and after 4 weeks of treatment. Statistically significant Intraclass Correlation Coefficient (ICC 2,1 ) values were reported for the FABQPA, FABQW, SPADI Pain, SPADI Disability, and NPRS. A statistically significant moderate relationship between the FABQPA subscale, SPADI subscale, and NPRS could not be established prior to and after 4 weeks of pragmatically applied PT. Statistically significant differences were observed between the initial evaluation and four-week follow-up for the FABQPA, SPADI Pain, SPADI Disability, and NPRS (p < 0.01). Since a meaningful relationship between the FABQ, SPADI, and NPRS did not exist, it suggests that the FABQPA may be measuring a metric other than pain. This study suggests that the FABQW may not be sensitive to change over time.

To investigate the effects of a shoulder sling on balance in patients with hemiplegia. Twenty-seven hemiplegic stroke patients (right 13, left 14) were enrolled in this study. The subjects' movement in their centers of gravity (COGs) during their static and dynamic balance tests was measured with their eyes open in each sling condition-without a sling, with Bobath's axillary support (Bobath sling), and with a simple arm sling. The percent times in quadrant, overall, anterior/posterior, and medial/lateral stability indexes were measured using a posturography platform (Biodex Balance System SD). Functional balance was evaluated using the Berg Balance Scale and the Trunk Impairment Scale. All balance tests were performed with each sling in random order. The COGs of right hemiplegic stroke patients and all hemiplegic stroke patients shifted to, respectively, the right and posterior quadrants during the static balance test without a sling (p<0.05). This weight asymmetry pattern did not improve with either the Bobath or the simple arm sling. There was no significant improvement in any stability index during either the static or the dynamic balance tests in any sling condition. The right and posterior deviations of the hemiplegic stroke patients' COGs were maintained during the application of the shoulder slings, and there were no significant effects of the shoulder slings on the patients' balance in the standing still position.

The purpose of this study was to measure the additional effect of adding interferential current (IFC) to an exercise and manual therapy program for patients with unilateral shoulder impingement syndrome. Forty-five participants were randomly assigned to group 1 (exercise and manual therapy), group 2 (exercise and manual therapy + IFC), or group 3 (exercise and manual therapy + placebo ultrasound). Individuals participated in 16 treatment sessions, twice a week for 8 weeks. The primary outcome of the study was total score of the Shoulder Pain and Disability Index (SPADI). The secondary outcomes were the pain and disability subscales of SPADI, Numeric Rating Scale, and Pain-Related Self-Statement Scale. Adjusted between-group mean differences (MDs) and 95% confidence intervals (CIs) were calculated using linear mixed models. After 16 treatment sessions, statistically significant but not clinically important differences were identified in favor of the exercise and manual therapy program alone in the SPADI-total (group 1 vs group 2, MD 11.12 points, 95% CI 5.90-16.35; group 1 vs group 3, MD 13.43 points, 95% CI 8.21-18.65). Similar results were identified for secondary outcomes. The addition of IFC does not generate greater clinical effects in an exercise and manual therapy program for individuals with unilateral shoulder impingement syndrome. Copyright © 2018.

[Purpose] The aim of our study was to compare the initial effects of scapular proprioceptive neuromuscular facilitation techniques and classic exercise interventions with physiotherapy modalities on pain, scapular dyskinesis, range of motion, and function in adhesive capsulitis. [Subjects and Methods] Fifty-three subjects were allocated to 3 groups: scapular proprioceptive neuromuscular facilitation exercies and physiotherapy modalities, classic exercise and physiotherapy modalities, and only physiotherapy modalities. The intervention was applied in a single session. The Visual Analog Scale, Lateral Scapular Slide Test, range of motion and Simple Shoulder Test were evaluated before and just after the one-hour intervention in the same session (all in one session). [Results] All of the groups showed significant differences in shoulder flexion and abduction range of motion and Simple Shoulder Test scores. There were statistically significant differences in Visual Analog Scale scores in the proprioceptive neuromuscular facilitation and control groups, and no treatment method had significant effect on the Lateral Scapular Slide Test results. There were no statistically significant differences between the groups before and after the intervention. [Conclusion] Proprioceptive neuromuscular facilitation, classic exercise, and physiotherapy modalities had immediate effects on adhesive capsulitis in our study. However, there was no additional benefit of exercises in one session over physiotherapy modalities. Also, an effective treatment regimen for shoulder rehabilitation of adhesive capsulitis patients should include scapular exercises. PMID:27190456

Single-blind randomized clinical trial, with a follow-up of 24 weeks. To determine the effects of hyperthermia via localized microwave diathermy on pain and disability in comparison to subacromial corticosteroid injections in patients with rotator cuff tendinopathy. Hyperthermia improves symptoms and function in several painful musculoskeletal disorders. However, the effects of microwave diathermy in rotator cuff tendinopathy have not yet been established. Ninety-two patients with rotator cuff tendinopathy and pain lasting for at least 3 months were recruited from the outpatient clinic of the Department of Orthopaedics and Traumatology, University Hospital, Rome, Italy. Participants were randomly allocated to either local microwave diathermy or subacromial corticosteroids. The primary outcome measure was the short form of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH). Secondary outcome measures were the Constant-Murley shoulder outcome score and a visual analog scale for pain assessment. At the end of treatment and at follow-up, both treatment groups experienced improvements in all outcome measures relative to baseline values. Changes over time in QuickDASH, Constant-Murley, and visual analog scale scores were not different between treatment arms. In patients with rotator cuff tendinopathy, the effects of localized microwave diathermy on disability, shoulder function, and pain are equivalent to those elicited by subacromial corticosteroid injections.

The aim of this study was to investigate short-term and long-term treatment effects of dry needling (DN) and manual pressure (MP) technique with the primary goal of determining if DN has better effects on disability, pain, and muscle characteristics in treating myofascial neck/shoulder pain in women. In this randomized clinical trial, 42 female office workers with myofascial neck/shoulder pain were randomly allocated to either a DN or MP group and received 4 treatments. They were evaluated with the Neck Disability Index, general numeric rating scale, pressure pain threshold, and muscle characteristics before and after treatment. For each outcome parameter, a linear mixed-model analysis was applied to reveal group-by-time interaction effects or main effects for the factor "time." No significant differences were found between DN and MP. In both groups, significant improvement in the Neck Disability Index was observed after 4 treatments and 3 months (P < .001); the general numerical rating scale also significantly decreased after 3 months. After the 4-week treatment program, there was a significant improvement in pain pressure threshold, muscle elasticity, and stiffness. Both treatment techniques lead to short-term and long-term treatment effects. Dry needling was found to be no more effective than MP in the treatment of myofascial neck/shoulder pain.

Scaling approach in predicting the seatbelt loading and kinematics of vulnerable occupants: How far can we go?

PubMed

2016-09-01

Occupants with extreme body size and shape, such as the small female or the obese, were reported to sustain high risk of injury in motor vehicle crashes (MVCs). Dimensional scaling approaches are widely used in injury biomechanics research based on the assumption of geometrical similarity. However, its application scope has not been quantified ever since. The objective of this study is to demonstrate the valid range of scaling approaches in predicting the impact response of the occupants with focus on the vulnerable populations. The present analysis was based on a data set consisting of 60 previously reported frontal crash tests in the same sled buck representing a typical mid-size passenger car. The tests included two categories of human surrogates: 9 postmortem human surrogates (PMHS) of different anthropometries (stature range: 147-189 cm; weight range: 27-151 kg) and 5 anthropomorphic test devices (ATDs). The impact response was considered including the restraint loads and the kinematics of multiple body segments. For each category of the human surrogates, a mid-size occupant was selected as a baseline and the impact response was scaled specifically to another subject based on either the body mass (body shape) or stature (the overall body size). To identify the valid range of the scaling approach, the scaled response was compared to the experimental results using assessment scores on the peak value, peak timing (the time when the peak value occurred), and the overall curve shape ranging from 0 (extremely poor) to 1 (perfect match). Scores of 0.7 to 0.8 and 0.8 to 1.0 indicate fair and acceptable prediction. For both ATDs and PMHS, the scaling factor derived from body mass proved an overall good predictor of the peak timing for the shoulder belt (0.868, 0.829) and the lap belt (0.858, 0.774) and for the peak value of the lap belt force (0.796, 0.869). Scaled kinematics based on body stature provided fair or acceptable prediction on the overall head/shoulder kinematics (0.741, 0.822 for the head; 0.817, 0.728 for the shoulder) regardless of the anthropometry. The scaling approach exhibited poor prediction capability on the curve shape for the restraint force (0.494 and 0.546 for the shoulder belt; 0.585 and 0.530 for the lap belt). It also cannot well predict the excursion of the pelvis and the knee. The results revealed that for the peak lap belt force and the forward motion of the head and shoulder, the underlying linear relationship with body size and shape is valid over a wide anthropometric range. The chaotic nature of the dynamic response cannot be fully recovered by the assumption of the whole-body geometrical similarity, especially for the curve shape. The valid range of the scaling approach established in this study can be reasonably referenced in predicting the impact response of a given specific population with expected deviation. Application of this knowledge also includes proposing strategies for restraint configuration and providing reference for ATD and/or human body model (HBM) development for vulnerable occupants.

Introduction Periarthritis (PA) shoulder characterised by pain and restricted range of motion has a plethora of treatment options with inconclusive evidence. Platelet Rich Plasma (PRP) is an emerging treatment option and its efficacy needs to be examined and compared with other routine interventions. Aim To assess the efficacy of PRP injection and compare it with corticosteroid injection and ultrasonic therapy in the treatment of PA shoulder. Materials and Methods Patients with PA shoulder (n=195) were randomised to receive single injection of PRP (2 ml) or corticosteroid (80 mg of methylprednisolone) or ultrasonic therapy (seven sittings in two weeks; 1.5 W/cm2, 1 MHz, continuous mode). All participants were also advised to perform a home based 10 minute exercise therapy. The primary outcome measure was active range of motion of the shoulder. Secondary outcome measures used were Visual Analogue Scale (VAS) for pain and a shortened version of Disabilities of the Arm, Shoulder and Hand (QuickDASH) for function. Participants were evaluated at 0, 3, 6 and 12 weeks. Chi-square test, one way and repeated measures of ANOVA tests were used to determine significant differences. Results PRP treatment resulted in statistically significant improvements over corticosteroid and ultrasonic therapy in active as well as passive range of motion of shoulder, VAS and QuickDASH at 12 weeks. At six weeks, PRP treatment resulted in statistically significant improvements over ultrasonic therapy in VAS and QuickDASH. No major adverse effects were observed. Conclusion This study demonstrates that single injection of PRP is effective and better than corticosteroid injection or ultrasonic therapy in treatment of PA shoulder. PMID:28658861

The impending burden of revision shoulder arthroplasty has increased interest in outcomes of revision procedures. Painful glenoid arthrosis following hemiarthroplasty is a common cause of reoperation, and conversion to anatomic total shoulder arthroplasty is one option. We identified patients who underwent revision of painful hemiarthroplasty to total shoulder arthroplasty over a 15-year period in a single tertiary-care health system. Presurgical and operative data were analyzed for 28 patients who met the inclusion and exclusion criteria. Patients were contacted at a minimum of 2 years' follow-up after revision surgery for functional outcome scores, reoperations, and implant survival. The 2- and 5-year implant survival rates were 93% and 86%, respectively. Functional outcomes were obtained from 21 patients with surviving implants. The mean American Shoulder and Elbow Surgeons score, visual analog scale score for pain, and Single Assessment Numerical Evaluation score were 78 ± 20, 2.3 ± 2.6, and 71 ± 24, respectively. The mean Short Form 12 mental and physical scores were 49 ± 10 and 43 ± 9, respectively. Of the patients, 17 (81%) were either satisfied or very satisfied with their outcome. Complications were seen in 10 patients (36%), and 6 patients (21%) required reoperation. Anatomic total shoulder arthroplasty following hemiarthroplasty can achieve successful outcomes and implant survival rates. Given our poor understanding of reverse shoulder arthroplasty longevity, this procedure should remain an option for patients with glenoid arthrosis and an intact rotator cuff.

Although reverse shoulder arthroplasty provides excellent clinical results in appropriately selected patients, loss of external and internal rotation may occur. Component selection, design, and placement affect postoperative results. Recent studies considered the effect of humeral component version on functional results. The current study investigated whether humeral stem retroversion affects the outcomes of reverse shoulder arthroplasty with a retrospective review of a multisurgeon, industry-sponsored, prospectively gathered database of a single reverse shoulder arthroplasty implant. All patients had at least 2-year follow-up. Clinical outcomes, including American Shoulder and Elbow Surgeons score, visual analog scale pain score, Short Form-12 Mental and Physical Component scores, range of motion, and internal rotation function, were compared between patients with humeral retroversion of 10° or less (group A) and those with humeral retroversion of 20° or greater (group B). Radiographic outcomes were compared. The analysis included 64 patients (group A, 29 patients; group B, 35 patients). No clinical or statistically significant difference was found in American Shoulder and Elbow Surgeons scores. Both groups showed statistical and clinical improvement vs preoperative scores, with group A averaging 77.8 and group B averaging 79.2 at final follow-up. No differences were found between groups in range of motion or ability to perform tasks that require shoulder internal rotation. Patients can expect good clinical improvement after reverse shoulder arthroplasty. No difference was found in clinical or radiologic outcomes based on humeral component retroversion. Despite the theoretical increase in external rotation when the humeral component is placed closer to native retroversion, the results did not show this effect. [Orthopedics. 2017; 40(3):179-186.].

To evaluate the correlation between indirect magnetic resonance (MR) arthrographic imaging findings and the clinical symptoms and prognosis of patients with frozen shoulder. Indirect MR arthrography was performed for 52 patients with primary frozen shoulder (mean age 55.1 ± 9.0 years) and 52 individuals without frozen shoulder (mean age 53.1 ± 10.7 years); capsular thickening and enhancement of the axillary recess as well as soft tissue thickening of the rotator interval were evaluated. Clinical symptom severity was assessed using the Visual Analogue Scale for Pain (VAS Pain), simple shoulder test (SST), Constant score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM). At 6-month follow-up, we evaluated whether MR arthrography findings correlated with the clinical symptoms and prognosis. Capsular thickening and enhancement of the axillary recess as well as soft tissue thickening of the rotator interval were significantly greater in the patient group than in the controls (p < 0.001). Capsular thickening of the axillary recess did not correlate with clinical symptoms or ROM (n.s.); however, capsular enhancement correlated with clinical symptom severity according to VAS Pain (p = 0.005), SST (p = 0.046), and ASES scores (p = 0.009). Soft tissue thickening of the rotator interval did not correlate with clinical symptom severity, but was associated with external rotation limitation (p = 0.002). However, none of the parameters correlated with clinical symptoms at 6-month follow-up. Indirect MR arthrography provided ancillary findings, especially with capsular enhancement, for evaluating clinical symptom severity of frozen shoulder, but did not reflect the prognosis. MR findings in frozen shoulder should not replace clinical judgments regarding further prognosis and treatment decisions. IV.

Shoulder pain of musculoskeletal origin is the main cause of upper limb pain of non-traumatic origin. Despite being one of the most common reasons for consultation, there is no established protocol for treatment due to the complexity of its etiology. However, it has been shown that the presence of myofascial trigger points on the shoulder muscles is a common condition associated with patients suffering from shoulder pain. This protocol has been created which describes the design of a randomized controlled trial to evaluate the effectiveness of the inclusion of dry needling (DN) within a protocol of manual physiotherapy and therapeutic exercise in the treatment of chronic shoulder pain of unspecific origin. Thirty-six participants aged 18-65 years will be recruited having mechanical chronic shoulder pain on unspecific origin and meeting the inclusion criteria. These will be randomized to one of two interventions, (i) DN, manual physiotherapy and therapeutic exercise or (ii) sham DN, manual physiotherapy and therapeutic exercise. The protocol will cover 6 weeks of treatment, with a 6-month follow-up. Our main outcome measure will be the Visual Analogue Scale for pain. This is the first study to combine the use of DN, manual physiotherapy and an exercise program with a 6-month follow-up, thus becoming a new contribution to the treatment of chronic shoulder pain, while new lines of research may be established to help determine the effects of DN on chronic shoulder pain and the frequency and proper dosage.

To determine the efficacy of polydeoxyribonucleotide (PDRN) injection for rotator cuff disease (RCD). Case-controlled, retrospective, comparative study. Outpatient clinic at a university-affiliated tertiary care hospital. Patients (N=106) with chronic nontraumatic refractory RCD who were unresponsive to at least 1 month of conservative treatment: 55 patients received PDRN injection (PDRN group) and 51 continued conservative treatment (control group). Not applicable. Shoulder Pain and Disability Index, score on a visual analog scale of the average shoulder pain level, number of analgesic ingestions per day, isometric strength of shoulder abductor, active range of motion (flexion, abduction, internal rotation, external rotation), and maximal tear size of tendon on ultrasonography at pretreatment and 3 and 6 months postinjection. There was no significant difference between the 2 groups in terms of age, sex, shoulder affected, duration of symptoms, and ultrasonographic findings at pretreatment. Compared with the control group, the treatment group showed a significant improvement in Shoulder Pain and Disability Index, visual analog scale score, and number of analgesic ingestions per day. However, there was no difference in isometric strength, active range of motion, and maximal tear size of tendon. No adverse events were reported. To our knowledge, this is the first study to assess the efficacy of PDRN injection for patients with RCD. The PDRN injection group showed improvement in pain and subjective disability in patients with RCD and continued to show improvement for 3 months thereafter; the PDRN injection can be an optional treatment for patients with chronic RCD who show no response to other treatments.

Objective. To investigate the effect of workplace neck/shoulder strength training with and without regular supervision on neck/shoulder pain and headache among office workers. Method. A 20-week cluster randomized controlled trial among 351 office workers was randomized into three groups: two training groups with the same total amount of planned exercises three times per week (1) with supervision (3WS) throughout the intervention period, (2) with minimal supervision (3MS) only initially, and (3) a reference group (REF). Main outcome is self-reported pain intensity in neck and shoulder (scale 0–9) and headache (scale 0–10). Results. Intention-to-treat analyses showed a significant decrease in neck pain intensity the last 7 days in 3MS compared with REF: −0.5 ± 0.2 (P < 0.02) and a tendency for 3WS versus REF: −0.4 ± 0.2 (P < 0.07). Intensity of headache the last month decreased in both training groups: 3WS versus REF: −1.1 ± 0.2 (P < 0.001) and 3MS versus REF: −1.1 ± 0.2 (P < 0.001). Additionally, days of headache decreased 1.0 ± 0.5 in 3WS and 1.3 ± 0.5 in 3MS versus REF. There were no differences between the two training groups for any of the variables. Conclusion. Neck/shoulder training at the workplace reduced neck pain and headache among office workers independently of the extent of supervision. This finding has important practical implications for future workplace interventions. PMID:24701581

Shoulder pain occurs commonly in food service workers (FSWs) who repetitively perform motions of the upper limbs. Myofascial trigger points (MTrPs) on the upper trapezius (UT) are among the most common musculoskeletal shoulder pain syndromes. This study determined the psychological, posture, mobility, and strength factors associated with pain severity in FSWs with UT pain due to MTrPs.In this cross-sectional study, we measured 17 variables in 163 FSWs with UT pain due to MTrPs: a visual analog scale (VAS) pain score, age, sex, Borg rating of perceived exertion (BRPE) scale, beck depression inventory, forward head posture angle, rounded shoulder angle (RSA), shoulder slope angle, scapular downward rotation ratio, cervical lateral-bending side difference angle, cervical rotation side difference angle, glenohumeral internal rotation angle, shoulder horizontal adduction angle, serratus anterior (SA) strength, lower trapezius (LT) strength, bicep strength, and glenohumeral external rotator strength, in 163 FSWs with UT pain due to MTrPs.The model for factors influencing UT pain with MTrPs included SA strength, age, BRPE, LT strength, and RSA as predictor variables that accounted for 68.7% of the variance in VAS (P < .001) in multiple regression models with a stepwise selection procedure. The following were independent variables influencing the VAS in the order of standardized coefficients: SA strength (β = -0.380), age (β = 0.287), BRPE (β = 0.239), LT strength (β = -0.195), and RSA (β = 0.125).SA strength, age, BRPE, LT strength, and RSA variables should be considered when evaluating and intervening in UT pain with MTrPs in FSWs.

The aim of the present microleakage study was to assess the sealing ability of nanohybrid composite crowns with different finish lines exposed to simulated mechanical periodontal treatment (SMPT). After sample size calculation (α=0.05; β=0.20; δ=1.0; σ=0.8), sixty extracted mandibular molars were divided into four groups (N.=15): G1, 90° shoulder; G2, beveled 90° shoulder; G3, 90° shoulder and SMPT; G4, beveled 90° shoulder and SMPT. Tooth preparations were carried out by means of diamond burs and Arkansas stones. The buildup of crowns was performed with a nanohybrid composite on master casts obtained after polyether impressions and crowns were cemented with self-adhesive cement. Groups G3 and G4 were subjected to the equivalent of five years of semestral mechanical periodontal scaling with Gracey curettes (2-mm long strokes, 5 N). Samples were immersed into a methylene blue supersaturated solution for 10 minutes. Microleakage was measured by stereomicroscopic observation of multiple sections of the samples and leakage data underwent statistical analysis with non-parametric tests. Marginal microleakage was 1.53±1.27% and 17.60±12.72% of the length of the adhesive interface in G1 and G2, respectively. SMPT reduced dye penetration (P<0.001) with G3 not leaking at all and G4 leaking along the 5.58±1.84% of the adhesive interface. The bevel preparation significantly worsened the marginal seal both in control and treated crowns (P<0.001). Microleakage of nanohybrid composite crowns increased by adding a bevel to a 90° shoulder preparation and diminished after SMPT.

Elite cello playing requires complex and refined motor control. Cellists are prone to right shoulder and thoracolumbar injuries. Research informing injury management of cellists and cello pedagogy is limited. The aims of this study were to quantify the torso, right shoulder, and elbow joint movement used by elite cellists while performing a fundamental playing task, a C major scale, under two volume conditions. An eight degrees of freedom upper limb biomechanical model was applied to 3D motion capture data of the torso, upper arm, and forearm for 31 cellists with a mean experience of 19.4 yrs (SD 9.1). Two-factor ANOVA compared the joint positions between the four cello strings and two volume conditions. Significant (p<0.05) effects were found for either the string and/or volume conditions across all torso, shoulder, and elbow joint degrees of freedom. The torso was consistently positioned in left rotation from 5.0° (SD 5.6) at the beginning of the scale, increasing to 16.3° (5.5) at its apogee. The greatest mean shoulder flexion, internal rotation, and abduction joint angles were observed when playing at the tip of the bow on the top string (A): 107.2° (11.6), 59.1° (7.1), and -76.9° (15.7), respectively, during loud playing. Elite cellists use specific movement patterns to achieve string crossings and volume regulation during fundamental playing tasks. Implications of the static left-rotated torso posture and high degrees of combined shoulder flexion and internal rotation can be used to inform clinical and pedagogical practices.

To investigate the effectiveness of traditional manual acupuncture combined with rehabilitation therapy versus rehabilitation therapy alone for shoulder hand syndrome after stroke. PubMed, EMBASE, the Cochrane Library, Chinese Biomedicine Database, China National Knowledge Infrastructure, VIP Information Database, Wan Fang Database and reference lists of the eligible studies were searched up to July 2017 for relevant studies. Randomized controlled trials that compared the combined effects of traditional manual acupuncture and rehabilitation therapy to rehabilitation therapy alone for shoulder hand syndrome after stroke were included. Two reviewers independently screened the searched records, extracted the data and assessed risk of bias of the included studies. The treatment effect sizes were pooled in a meta-analysis using RevMan 5.3 software. A total of 20 studies involving 1918 participants were included in this study. Compared to rehabilitation therapy alone, the combined therapy significantly reduced pain on the visual analogue scale and improved limb movement on the Fugl-Meyer Assessment scale and the performance of activities of daily living (ADL) on the Barthel Index scale or Modified Barthel Index scale. Of these, the visual analogue scale score changes were significantly higher (mean difference = 1.49, 95% confidence interval = 1.15-1.82, P < 0.00001) favoring the combined therapy after treatment, with severe heterogeneity ( I 2  = 71%, P = 0.0005). Current evidence suggests that traditional manual acupuncture integrated with rehabilitation therapy is more effective in alleviating pain, improving limb movement and ADL. However, considering the relatively low quality of available evidence, further rigorously designed and large-scale randomized controlled trials are needed to confirm the results.

2014-01-01

In recent years, research indicated that the problematic effects of Internet use must be examined together with individual differences present in its users with which such effects are contingent. This study examined loneliness in adolescents as a mediator of the relationship between shyness and their generalized problematic Internet use (PIU). A total of 1469 adolescents (48.5% male, 51.5% female) from Grade 8 and Grade 9 classes participated in this study. Using the Social Reticence Scale (SRS), the revised UCLA Loneliness scale and the Generalized Problematic Internet Use scale, initial findings indicated significant correlations among the three variables. Results from the study further revealed that loneliness completely mediated the relationship between shyness and generalized problematic Internet use. Implications for intervention work addressing both loneliness and shyness issues facing adolescents who are problematic users of the Internet were discussed.

The patient's position during an axillary thoracotomy can cause postoperative pain and decrease mobility of the ipsilateral shoulder. In this study, we assessed whether the implementation of a standardized analgesia program using transcutaneous electrical nerve stimulation (TENS) decreases local pain and improves ipsilateral shoulder mobility. Randomized, single-blind, single-center clinical trial of 50 patients who had undergone anatomical lung resection via axillary muscle-sparing thoracotomy. Patients were treated with TENS devices for 30 minutes every 8 hours, beginning on postoperative day 1. Pain and mobility of the affected limb were recorded at the same time on postoperative days 1 through 3. A visual analogue scale was used for pain assessment and shoulder mobility was assessed with a goniometer. Results were compared using a non-parametric test. Twenty-five patients were randomized to each group. Mean age of the control group was 62.7±9.3 years and 63.4±10.2 years in the experimental group. Shoulder mobility parameters were similar in both groups on all postoperative days. However, pain during flexion significantly decreased on day 2 (P=.03) and day 3 (P=.04) in the experimental group. The use of TENS decreases pain from shoulder flexion in patients undergoing axillary thoracotomy for pulmonary resection. Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.

Hamer, P; Bunker, TD

2014-01-01

INTRODUCTION The aim of this prospective study was to assess the immediate and long-term effectiveness of arthroscopic capsular release in a large cohort of patients with a precise and isolated diagnosis of stage II idiopathic frozen shoulder. METHODS All patients underwent a preoperative evaluation. Patients with secondary frozen shoulder and those with concurrent pathology at arthroscopy were excluded. This left 136 patients with a stage II arthroscopically confirmed idiopathic frozen shoulder. At each postoperative attendance, a record was made of pain, function and range of motion. At 12 months, the Oxford shoulder score was calculated, and pain and range of motion were assessed. RESULTS Fifty per cent achieved good pain relief within a week and eighty per cent within six weeks of arthroscopic capsular release. The mean preoperative visual analogue scale pain score was 6.6 and the mean postoperative score was 1.0. The mean time to achieving good pain relief was 16 days following surgery. No patient could sleep through the night prior to surgery while 90% reported having a complete night’s sleep at a mean of 12 days after surgery. The mean postoperative Oxford shoulder score was 38/48 and the mean improvement was 19.2. CONCLUSIONS This large series demonstrates that arthroscopic capsular release is a safe procedure, with rapid improvement in pain and a marked improvement in range of motion. PMID:24417832

To determine the subacute effects of cervicothoracic spinal thrust/non-thrust in addition to shoulder non-thrust plus exercise in patients with subacromial pathology. This was a randomized, single blinded controlled trial pilot study. This trial was registered at ClinicalTrials.gov (NCT01753271) and reported according to Consolidated Standards of Reporting Trials requirements. Patients were randomly assigned to either shoulder treatment plus cervicothoracic spinal thrust/non-thrust or shoulder treatment-only group. Primary outcomes were average pain intensity (Numeric Pain Rating Scale) and physical function (Shoulder Pain and Disability Index) at 2 weeks, 4 weeks, and patient discharge. 18 patients, mean age 43.1(15.8) years satisfied the eligibility criteria and were analyzed for follow-up data. Both groups showed statistically significant improvements in both pain and function at 2 weeks, 4 weeks, and discharge. The between-group differences for changes in pain or physical function were not significant at any time point. The addition of cervicothoracic spinal thrust/non-thrust to the shoulder treatment-only group did not significantly alter improvement in pain or function in patients with subacromial pathology. Both approaches appeared to provide an equally notable benefit. Both groups improved on all outcomes and met the criteria for clinical relevance for both pain and function. 2b.

Methods: Systematic literature searches were performed to identify self administered shoulder disability questionnaires. A checklist was developed to evaluate and compare the clinimetric quality of the instruments. Results: Two reviewers identified and evaluated 16 questionnaires by our checklist. Most studies were found for the Disability of the Arm, Shoulder, and Hand scale (DASH), the Shoulder Pain and Disability Index (SPADI), and the American Shoulder and Elbow Surgeons Standardised Shoulder Assessment Form (ASES). None of the questionnaires demonstrated satisfactory results for all properties. Most questionnaires claim to measure several domains (for example, pain, physical, emotional, and social functioning), yet dimensionality was studied in only three instruments. The internal consistency was calculated for seven questionnaires and only one received an adequate rating. Twelve questionnaires received positive ratings for construct validity, although depending on the population studied, four of these questionnaires received poor ratings too. Seven questionnaires were shown to have adequate test-retest reliability (ICC >0.70), but five questionnaires were tested inadequately. In most clinimetric studies only small sample sizes (n<43) were used. Nearly all publications lacked information on the interpretation of scores. Conclusion: The DASH, SPADI, and ASES have been studied most extensively, and yet even published validation studies of these instruments have limitations in study design, sample sizes, or evidence for dimensionality. Overall, the DASH received the best ratings for its clinimetric properties. PMID:15020324

2016-06-01

The purpose of this study was to investigate the effects of brain-computer interface (BCI)-controlled functional electrical stimulation (FES) training on shoulder subluxation of patients with stroke. Twenty subjects were randomly divided into two groups: the BCI-FES group (n = 10) and the FES group (n = 10). Patients in the BCI-FES group were administered conventional therapy with the BCI-FES on the shoulder subluxation area of the paretic upper extremity, five times per week during 6 weeks, while the FES group received conventional therapy with FES only. All patients were assessed for shoulder subluxation (vertical distance, VD; horizontal distance, HD), pain (visual analogue scale, VAS) and the Manual Function Test (MFT) at the time of recruitment to the study and after 6 weeks of the intervention. The BCI-FES group demonstrated significant improvements in VD, HD, VAS and MFT after the intervention period, while the FES group demonstrated significant improvements in HD, VAS and MFT. There were also significant differences in the VD and two items (shoulder flexion and abduction) of the MFT between the two groups. The results of this study suggest that BCI-FES training may be effective in improving shoulder subluxation of patients with stroke by facilitating motor recovery.

Neck-shoulder symptoms are frequent among workers. Psychosocial factors at work have been associated with neck-shoulder symptoms, but few studies have examined job strain, the combined effect of high psychological demands (PD) and low decision latitude (DL). To examine the association between psychosocial factors at work and the prevalence of self-reported neck-shoulder symptoms among white-collar workers. In a cross-sectional study of 1543 white-collar workers, PD and DL at work were measured with Karasek's questionnaire. Prevalent cases were workers for whom neck-shoulder symptoms were present for >or=3 days during the previous 7 days and for whom pain intensity was greater than half the visual analogue scale. Gender and social support at work were evaluated as potential effect modifiers. Workers exposed to high job strain had a higher prevalence of neck-shoulder symptoms [adjusted prevalence ratio (PR): 1.54, 95% confidence interval (CI): 1.00-2.37]. No modifying effect of gender was observed in this association. The effect of job strain was stronger in workers with low social support (adjusted PR: 1.84, 95% CI: 0.92-3.68). These associations tended to be stronger and/or more precise when using alternative exposures and case definition. Namely, a stronger job strain effect was observed when a tertile cut-off was used to classify exposure (adjusted PR: 2.47, 95% CI: 1.15-5.32). These results suggest that primary prevention of neck-shoulder symptoms among white-collar workers should consider the exposure to job strain, especially when workers are exposed to low social support at work.

Fragmentation of the landscape by large-scale mining may affect Red-shouldered Hawk (Buteo lineatus) populations by reducing the amount of forested habitat available in a landscape and by creating fragmented forest parches surrounded by reclaimed mine lands. We examined habitat characteristics and relative abundance of Red-shouldered Hawks in reclaimed mine landscapes within four treatments: early-successional grassland habitat, mid-successional shrub/pole habitat, late-successional fragmented forest habitat, and late-successional intact forest habitat. We quantified microhabitat characteristics within an 11.3-m-radius plot centered on 156 vegetation plots throughout the four treatments. We surveyed 48 stations on and adjacent to three mines for Red-shouldered Hawks using standardized broadcast call techniques during February 2000-January 2001 and measured landscape characteristics within 1000-m buffer zones centered on each station from digitized aerial photographs. Mean abundance of Red-shouldered Hawks was significantly higher in the intact forest (x?? = 0.07 detections/ point, SE = 0.03) than the grassland (x?? = 0.01, SE = 0.01) treatment, but did not differ from the fragmented forest (x?? = 0.03, SE = 0.01) or shrub/pole (x?? = 0.03, SE = 0.01) treatments. Most microhabitat characteristics in both fragmented and intact forest differed from shrub/pole and grasslands. Amount of wetland was the most important characteristic determining presence of Red-shouldered Hawks in a forest-dominated landscape. More wetlands in the landscape may provide abundant amphibians and reptiles, which are important in the diet of Red-shouldered Hawks. ?? 2003 The Raptor Research Foundation, Inc.

To evaluate the clinical results and analyse the complications of total reverse shoulder replacement performed in our centre over an 8 year period. A retrospective study was conducted on 50 patients (52 shoulders), with a mean age of 70.15 years (range 51 to 84 years) between December 2004 and December 2012, who received a total reverse shoulder replacement, all performed by the same surgeon. The results have been evaluated according to clinical data, radiography study, a satisfaction scale, and the Constant scale, with a minimum follow-up of 16 months. Five of the cases (9.62%) had been intervened due to fractures of the proximal end of the humerus, 6 cases (11.53%) as surgical consequence of a prosthesis revision, 10 cases (19.23%) due to fracture sequelae, and 30 cases (59.62%) were patients with arthropathy due to a massive fracture of the rotator cuff. After a mean follow up of 35.78 months (range, 16-82), satisfactory clinical results were obtained in 80% of cases, with a mean preoperative Constant of 27.7 points, and reaching 67.1 points 12 months after the operation. On the visual analogue scale, 8.25 points were obtained before the surgery, which decreased to 2.25 points 12 months later. The complications rate was 15.38%, which were due to an intra-operative fracture (1.92%), deep infection (3.84%), instability (3.84%), and early mechanical loosening (3.84%). Scapular notching was observed in the radiographic study in 9 (17.3%) cases. After the results obtained, it could be said that total reverse shoulder replacement achieved encouraging results in the short term for the treatment of glenohumeral arthrosis and massive tears of the rotary cuff. On analysing our series, it can be seen that the complications rate is much higher when it is used to treat fracture sequelae in which there is a loss of proximal humerus bone stock.

Exploring Your Universe at UCLA: Steps to Developing and Sustaining a Large STEM Event

NASA Astrophysics Data System (ADS)

Curren, I. S.; Vican, L.; Sitarski, B.; Jewitt, D. C.

2015-12-01

Public STEM events are an excellent method to implement informal education and for scientists and educators to interact with their community. The benefits of such events are twofold. First and foremost, science enthusiasts and students both young and old, in particular, are exposed to STEM in a way that is accessible, fun, and not as stringent as may be presented in classrooms where testing is an underlying goal. Second, scientists and educators are given the opportunity to engage with the public and share their science to an audience who may not have a scientific background, thereby encouraging scientists to develop good communication practices and skills. In 2009 graduate student members of Astronomy Live!, an outreach organization in the UCLA Department of Physics and Astronomy, started a free and public event on the campus that featured a dozen hands-on outreach activities. The event, though small at the time, was a success and it was decided to make it an annual occurrence. Thus, Exploring Your Universe (EYU) was born. Primarily through word of mouth, the event has grown every year, both in number of attendees and number of volunteers. In 2009, approximately 1000 people attended and 20 students volunteered over the course of an eight-hour day. In 2014, participation was at an all-time high with close to 6000 attendees and over 400 volunteers from all departments in the Division of Physical Sciences (plus many non-divisional departments and institutes, as well as non-UCLA organizations). The event, which is the largest STEM event at UCLA and one of the largest in Los Angeles, now features near 100 hands-on activities that span many STEM fields. EYU has been featured by the UCLA news outlets, Daily Bruin and UCLA Today, and is often lauded as their favorite event of the year by attendees and volunteers alike. The event is entirely student-run, though volunteers include faculty, staff, researchers and students alike. As the event has grown, new systems for managing its many aspects have been adopted. Here, we will present the details of how the event was created and has remained successful, and sustainable.

What is the effect of a shoulder-strengthening program to prevent shoulder pain among junior female team handball players?

2017-01-01

Background Excessively high stresses are applied to the shoulder joint of handball players, mainly caused by overhead throwing. Shoulder pain is a significant problem among junior female team handball players and both male and female top-level team handball players in Norway. Method A randomized selection was performed among the best female junior teams (J 16) in the Trøndelag region of Norway in the 2014–2015 season. Three teams were randomized to the intervention group and three teams to the control group. Players in the intervention group (n=53) participated in a seven-month, three-times-a-week shoulder-muscle strength-training program, while those in the control group (n=53) participated in a comparable handball training, but did not conduct any specific strength training during the season. Results A strength-training program had no effect on the prevention of shoulder pain. Overall, the players reported shoulder pain, but graded the pain low on visual analog scale (VAS). Both the intervention group and the control group reported pain under 1 on VAS at baseline and posttest, and there was no significant difference within or between the groups when it came to the intensity of pain reported on VAS. A significant difference (p<0.048) was found between the groups on the sport-specific part of the quick-Disability of the Arm, Shoulder and Hand (DASH) form, but it did not fulfill the minimal demand to change and the players scored it low, something that indicates little functional problems when it comes to team handball. The intervention group was significantly stronger (p<0.008) on the push-ups test compared to the control group on the posttest. The intervention group increased the number of push-ups from 3.1 to 6.4, while the control group went from 2.3 to 3.6. Aside from this, there were no significant differences in between the groups. Conclusion A shoulder-strengthening program had no effect on the prevention of shoulder pain among junior female team handball players. PMID:28435335

Shoulder pain is a significant problem among junior female team handball players and both male and female top-level team handball players in Norway. A randomized selection was performed among the best female junior teams (J 16) in the Trøndelag region of Norway in the 2014-2015 season. Three teams were randomized to the intervention group and three teams to the control group. Players in the intervention group (n=53) participated in a seven-month, three-times-a-week shoulder-muscle strength-training program, while those in the control group (n=53) participated in a comparable handball training, but did not conduct any specific strength training during the season. A strength-training program had no effect on the prevention of shoulder pain. Overall, the players reported shoulder pain, but graded the pain low on visual analog scale (VAS). Both the intervention group and the control group reported pain under 1 on VAS at baseline and posttest, and there was no significant difference within or between the groups when it came to the intensity of pain reported on VAS. A significant difference ( p <0.048) was found between the groups on the sport-specific part of the quick-Disability of the Arm, Shoulder and Hand (DASH) form, but it did not fulfill the minimal demand to change and the players scored it low, something that indicates little functional problems when it comes to team handball. The intervention group was significantly stronger ( p <0.008) on the push-ups test compared to the control group on the posttest. The intervention group increased the number of push-ups from 3.1 to 6.4, while the control group went from 2.3 to 3.6. Aside from this, there were no significant differences in between the groups. A shoulder-strengthening program had no effect on the prevention of shoulder pain among junior female team handball players.

Primary hyperhidrosis, although extensively documented in adults, typically has onset that dates back to early childhood. It is an unpleasant and socially disabling problem for the affected child, but little attention has been paid to the disease in adolescents. The objective of the current study was to evaluate the effectiveness of botulinum toxin type A (BTXA) in adolescents with primary palmar and axillary hyperhidrosis and to determine its effect on quality of life and social isolation. Thirty-five individuals (17 girls, 18 boys) with moderate to severe palmar and axillary hyperhidrosis were treated with BTXA (onabotulinum). Patients were examined at baseline and 6 months after treatment. The Hyperhidrosis Disease Severity Scale (HDSS) was used to evaluate disease severity and the Children's Dermatology Life Quality Index (CDLQI) was used to assess quality of life. The University of California at Los Angeles loneliness scale (UCLA version 3) was used to assess personal perception of loneliness and social isolation. The median age of the participants was 14 years, and 48.6% were female. Twenty-one had palmar hyperhidrosis, and 14 had axillary hyperhidrosis. Total CDLQI and social isolation scores decreased significantly after treatment with BTXA (both p < 0.001). There was a significant difference between pre- and post-treatment levels of severity of hyperhidrosis. No statistically significant difference was documented for CDLQI and UCLA scores between boys and girls. Treatment of hyperhidrosis with BTXA resulted in improvement in quality of life, social skills, and activities. © 2014 Wiley Periodicals, Inc.

Persistent Complex Bereavement Disorder (PCBD) is a newly proposed diagnosis placed in the Appendix of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as an invitation for further research. To date, no studies have examined the dimensionality of PCBD or explored whether different PCBD criteria domains relate in similar, versus differential, ways to other psychological conditions common to war-exposed bereaved youth, including symptoms of Posttraumatic Stress Disorder (PTSD) and depression. We evaluated the dimensionality of proposed PCBD B and C symptom domains, and their respective relations with measures of PTSD and depression, in 1142 bereaved Bosnian adolescents exposed to the 1992-1995 Bosnian civil war. Instruments included the UCLA PTSD Reaction Index, the Depression Self-Rating Scale, and the UCLA Grief Screening Scale (a prototype measure of PCBD symptoms). We investigated potential differences in grief, PTSD, and depression scores as a function of cause of death. We then examined hypothesized differential relations between PCBD B and C symptom domain subscales and selected external correlates, specifically measures of depression and the four-factor emotional numbing model of PTSD. Results of both analyses provide preliminary evidence of a multidimensional structure for PCBD in this population, in that the PCBD Criterion C subscale score covaried more strongly with each of the four PTSD factors and with depression than did PCBD Criterion B. We conclude by discussing theoretical, methodological, clinical, and policy-related implications linked to the ongoing study of essential features of PCBD.

In children with brachial plexus birth palsy (BPBP) undergoing tendon transfers to augment shoulder external rotation, it is unclear whether transfer of the latissimus dorsi with its combined latissimus dorsi and teres major (cLT) versus isolated teres major (iTM) tendon transfer yield different outcomes. Records of patients with BPBP who underwent shoulder tendon transfers to augment external rotation were retrospectively reviewed. Transfer type (cLT or iTM) was considered indiscriminate by virtue of surgeon preference. Modified Mallet Scale (mMS) and Active Movement Scale scores were recorded. Patients with <12 months' follow-up, C7 or lower palsy, humeral osteotomy, shoulder procedure(s) within 8 months, microsurgery within 1 year, or recurrent glenohumeral subluxation confirmed by postoperative imaging were excluded. Matched cohorts were identified within each tendon transfer group to yield similar preoperative shoulder function and glenohumeral alignment status. Outcomes for all tendon transfers as well as differences between cLT and iTM cohorts were analyzed. Among 121 cLT and 34 iTM transfers, 49 cLT and 14 iTM met the inclusion criteria. Subsequent matching of cohorts yielded 28 patients (14 cLT and 14 iTM). Average age at time of transfer was 3.0±1.4 years. Follow-up averaged 4.1±3.1 years. There were no statistically significant preoperative differences between cohorts, thus matching criteria were validated. Regardless of tendon(s) transferred, mMS external rotation improved (2.2 to 3.5, P<0.001), whereas mMS internal rotation decreased (3.8 to 3.2, P<0.001). When comparing matched cohorts, cLT transfer produced a greater mMS external rotation improvement than iTM (2.1 vs. 1.5, respectively; P=0.025). Loss of midline function (defined as mMS external rotation <3) occurred in 5 (35.7%) cLT and 2 (14.3%) iTM patients. Both cLT or iTM transfer are effective at augmenting shoulder external rotation in children with C5-C6 BPBP. Furthermore, cLT transfers may yield a larger improvement in external rotation in certain patients. However, both techniques slightly decrease shoulder internal rotation. Given that more total cLT patients lost midline function among matched cohorts, iTM transfer may still be considered when limited midline function is a concern. Level III.

Background Platelet-rich products (PRP) are widely used for rotator cuff tears. However, whether platelet-rich products produce superior clinical or radiological outcomes is controversial. This study aims to use meta-analysis to compare clinical and radiological outcomes between groups with or without platelet-rich products. Methods The Pubmed, Embase, and Cochrane library databases were searched for relevant studies published before April 20, 2013. Studies were selected that clearly reported a comparison between the use or not of platelet-rich products. The Constant, ASES, UCLA, and SST scale systems and the rotator cuff retear rate were evaluated. The weighted mean differences and relative risks were calculated using a fixed-effects model. Results Seven studies were enrolled in this meta-analysis. No significant differences were found for the Constant scale (0.73, 95% CI, −1.82 to 3.27, P = 0.58), ASES scale (−2.89, 95% CI, −6.31 to 0.53, P = 0.1), UCLA scale (−0.79, 95% CI, −2.20 to 0.63, P = 0.28), SST scale (0.34, 95% CI, −0.01 to 0.69, P = 0.05), and the overall rotator cuff retear rate (0.71, 95% CI, 0.48 to 1.05, P = 0.08). Subgroup analysis according to the initial tear size showed a lower retear rate in small- and medium-sized tears (0.33, 95% CI, 0.12 to 0.91, P = 0.03) after platelet-rich product application but no difference for large- and massive-sized tears (0.86, 95% CI, 0.60 to 1.23, P = 0.42). Conclusion In conclusion, the meta-analysis suggests that the platelet-rich products have no benefits on the overall clinical outcomes and retear rate for the arthroscopic repair of full-thickness rotator cuff tears. However, a decrease occurred in the rate of retears among patients treated with PRP for small- and medium-sized rotator cuff tears but not for large- and massive-sized tears.

In order to elucidate the genetic basis of autosomal dominant retinitis pigmentosa (adRP) in a large eight-generation family (UCLA-RP09) of British descent, we assessed linkage between the UCLA-RP09 adRP gene and numerous genetic loci, including eight adRP candidate genes, five anonymous adRP-linked DNA loci, and 20 phenotypic markers. Linkage to the UCLA-RP09 disease gene was excluded for all eight candidate genes analyzed, including rhodopsin (RP4) and peripherin/RDS (RP7), for the four adRP loci RP1, RP9, RP10 and RP11, as well as for 17 phenotypic markers. The anonymous DNA marker locus D17S938, linked to adRP locus RP13 on chromosome 17p13.1, yieldedmore » a suggestive but not statistically significant positive lod score. Linkage was confirmed between the UCLA-RP09 adRP gene and markers distal to D17S938 in the chromosomal region 17p13.3. A reanalysis of the original RP13 data from a South African adRP family of British descent, in conjunction with our UCLA-RP09 data, suggests that only one adRP locus exists on 17p but that it maps to a more telomeric position, at band 17p13.3, than previously reported. Confirmation of the involvement of RP13 in two presumably unrelated adRP families, both of British descent, suggests that this locus is a distinct adRP gene in a proportion of British, and possibly other, adRP families. 39 refs., 4 figs., 3 tabs.« less

HIV-associated cardiomyopathy (HIVCM) is of clinical concern in developing countries because of a high HIV-1 prevalence, especially subtype C, and limited access to highly active antiretroviral therapy (HAART). For these reasons, we investigated the direct and indirect effects of HIV-1 subtype C infection of cultured human cardiomyocytes and the mechanisms leading to cardiomyocytes damage; as well as a way to mitigate the damage. We evaluated a novel approach to mitigate HIVCM using a previously reported gp120 binding and HIV-1 neutralizing aptamer called UCLA1. We established a cell-based model of HIVCM by infecting human cardiomyocytes with cell-free HIV-1 or co-culturing human cardiomyocytes with HIV-infected monocyte derived macrophages (MDM). We discovered that HIV-1 subtype C unproductively (i.e. its life cycle is arrested after reverse transcription) infects cardiomyocytes. Furthermore, we found that HIV-1 initiates apoptosis of cardiomyocytes through caspase-9 activation, preferentially via the intrinsic or mitochondrial initiated pathway. CXCR4 receptor-using viruses were stronger inducers of apoptosis than CCR5 utilizing variants. Importantly, we discovered that HIV-1 induced apoptosis of cardiomyocytes was mitigated by UCLA1. However, UCLA1 had no protective effective on cardiomyocytes when apoptosis was triggered by HIV-infected MDM. When HIV-1 was treated with UCLA1 prior to infection of MDM, it failed to induce apoptosis of cardiomyocytes. These data suggest that HIV-1 causes a mitochondrial initiated apoptotic cascade, which signal through caspase-9, whereas HIV-1 infected MDM causes apoptosis predominantly via the death-receptor pathway, mediated by caspase-8. Furthermore the data suggest that UCLA1 protects cardiomyocytes from caspase-mediated apoptosis, directly by binding to HIV-1 and indirectly by preventing infection of MDM.

The aim of this study was to compare vertical and horizontal adjustments of castable abutments after conducting casting and soldering procedures. Twelve external hexagonal implants (3.75 × 10 mm) and their UCLA abutments were divided according their manufacturer and abutment type: PUN (plastic UCLA, Neodent), PUC (plastic UCLA, Conexão), PU3i (plastic UCLA, Biomet 3i), and PUTN (plastic UCLA with Tilite milled base, Neodent). Three infrastructures of a fixed partial implant-supported bridge with 3 elements were produced for each group. The measurements of vertical (VM) and horizontal (HM) misfits were obtained via scanning electron microscopy after completion of casting and soldering. The corresponding values were determined to be biomechanically acceptable to the system, and the results were rated as a percentage. Statistical analysis establishes differences between groups by chi-square after procedures, and McNeman's test was applied to analyze the influence of soldering over casting (α ≤ .05). For the values of VM and HM, respectively, when the casting process was complete, it was observed that 83.25% and 100% (PUTN), 33.3% and 27.75% (PUN), 33.3% and 88.8% (PUC), 33.3% and 94.35% (PU3i) represented acceptable values. After completing the requisite soldering, acceptable values were 50% and 94.35% (PUTN), 16.6% and 77.7% (PUN), 38.55% and 77.7% (PUC), and 27.75% and 94.35% (PU3i). Within the limitations of this study, it can be concluded that the premachined abutments presented more acceptable VM values. The HM values were within acceptable limits before and after the soldering procedure for most groups. Further, the soldering procedure resulted in an increase of VM in all groups.

The study was an exploratory, one group pretest/post-test study, with the objective of investigating the short-term effects of thoracic spine thrust manipulations (TSTMs) on patients with shoulder impingement syndrome (SIS). There is evidence that manual physical therapy that includes TSTM and non-thrust manipulation and exercise is effective for the treatment of patients with SIS. However, the relative contributions of specific manual therapy interventions are not known. To date, no published studies address the short-term effects of TSTM in the treatment of SIS. Fifty-six patients (40 males, 16 females; mean age 31.2+/-8.9) with SIS underwent a standardized shoulder examination, immediately followed by TSTM techniques. Outcomes measured were the Numeric Pain and Rating Scale (NPRS) and the Shoulder Pain and Disability Index (SPADI), all collected at baseline and at a 48-h follow-up period. Additionally, the Global Rating of Change Scale (GRCS) was collected at 48-h follow-up to measure patient perceived change. At 48-h follow-up, the NPRS change scores for Neer impingement sign, Hawkins impingement sign, resisted empty can, resisted external rotation, resisted internal rotation, and active abduction were all statistically significant (p<0.01). The reduction in the SPADI score was also statistically significant (p<0.001) and the mean GRCS score=1.4+/-2.5. In conclusion, TSTM provided a statistically significant decrease in self reported pain measures and disability in patients with SIS at 48-h follow-up.

Validated clinician outcome scores are considered less associated with psychosocial factors than patient-reported outcome measurements (PROMs). This belief may lead to misconceptions if both instruments are related to similar factors. We asked: In patients with chronic shoulder pain, what biopsychosocial factors are associated (1) with PROMs, and (2) with clinician-rated outcome measurements? All new patients between the ages of 18 and 65 with chronic shoulder pain from a unilateral shoulder injury admitted to a Swiss rehabilitation teaching hospital between May 2012 and January 2015 were screened for potential contributing biopsychosocial factors. During the study period, 314 patients were screened, and after applying prespecified criteria, 158 patients were evaluated. The median symptom duration was 9 months (interquartile range, 5.5-15 months), and 72% of the patients (114 patients) had rotator cuff tears, most of which were work injuries (59%, 93 patients) and were followed for a mean of 31.6 days (SD, 7.5 days). Exclusion criteria were concomitant injuries in another location, major or minor upper limb neuropathy, and inability to understand the validated available versions of PROMs. The PROMs were the DASH, the Brief Pain Inventory, and the Patient Global Impression of Change, before and after treatment (physiotherapy, cognitive therapy and vocational training). The Constant-Murley score was used as a clinician-rated outcome measurement. Statistical models were used to estimate associations between biopsychosocial factors and outcomes. Greater disability on the DASH was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale combined coefficient, 0.64; 95% CI, 0.25-1.03; p = 0.002) and social factors (language, professional qualification combined coefficient, -6.15; 95% CI, -11.09 to -1.22; p = 0.015). Greater pain on the Brief Pain Inventory was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale combined coefficient, 0.076; 95% CI, 0.021-0.13; p = 0.006). Poorer impression of change was associated with psychological factors (Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia coefficient, 0.93; 95% CI, 0.87-0.99; p = 0.026) and social factors (education, language, and professional qualification coefficient, 6.67; 95% CI, 2.77-16.10; p < 0.001). Worse clinician-rated outcome was associated only with psychological factors (Hospital Anxiety and Depression Scale (depression only), Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia combined coefficient, -0.35; 95% CI, -0.58 to -0.12; p = 0.003). Depressive symptoms and catastrophizing appear to be key factors influencing PROMs and clinician-rated outcomes. This study suggests revisiting the Constant-Murley score.

Shoulder instability is a relatively common condition occurring in 2% of the population. PROMIS (Patient-Reported Outcome Measurement Information System) was developed by the National Institutes of Health in an effort to advance patient-reported outcome (PRO) instruments by developing question banks for major health domains. To compare PROMIS instruments to current PRO instruments in patients who would be undergoing operative intervention for recurrent shoulder instability. Cohort study (diagnosis); Level of evidence, 2. A total of 74 patients with a primary diagnosis of shoulder instability who would be undergoing surgery were asked to fill out the American Shoulder and Elbow Surgeons shoulder assessment form (ASES), Marx shoulder activity scale (Marx), Short Form-36 Health Survey Physical Function subscale (SF-36 PF), Western Ontario Shoulder Instability Index (WOSI), PROMIS physical function computer adaptive test (PF CAT), and PROMIS upper extremity item bank (UE). Correlation between PRO instruments was defined as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), and poor (0.2-0.3). Utilization of the PROMIS UE demonstrated excellent correlation with the SF-36 PF ( r = 0.78, P < .01) and ASES ( r = 0.71, P < .01); there was excellent-good correlation with the EQ-5D ( r = 0.66, P < .01), WOSI ( r = 0.63, P < .01), and PROMIS PF CAT ( r = 0.63, P < .01). Utilization of the PROMIS PF CAT demonstrated excellent correlation with the SF-36 PF ( r = 0.72, P < .01); there was excellent-good correlation with the ASES ( r = 0.67, P < .01) and PROMIS UE ( r = 0.63, P < .01). When utilizing the PROMIS UE, ceiling effects were present in 28.6% of patients aged 18 to 21 years. Patients, on average, answered 4.6 ± 1.8 questions utilizing the PROMIS PF CAT. The PROMIS UE and PROMIS PF CAT demonstrated good to excellent correlation with common shoulder and upper extremity PRO instruments as well as the SF-36 PF in patients with shoulder instability. In patients aged ≤21 years, there were significant ceiling effects utilizing the PROMIS UE. While the PROMIS PF CAT appears appropriate for use in adults of any age, our findings demonstrate that the PROMIS UE has significant ceiling effects in patients with shoulder instability who are ≤21 years old, and we do not recommend use of the PROMIS UE in this population.

High prevalence of shoulder girdle muscles with myofascial trigger points in patients with shoulder pain

PubMed Central

Background Shoulder pain is reported to be highly prevalent and tends to be recurrent or persistent despite medical treatment. The pathophysiological mechanisms of shoulder pain are poorly understood. Furthermore, there is little evidence supporting the effectiveness of current treatment protocols. Although myofascial trigger points (MTrPs) are rarely mentioned in relation to shoulder pain, they may present an alternative underlying mechanism, which would provide new treatment targets through MTrP inactivation. While previous research has demonstrated that trained physiotherapists can reliably identify MTrPs in patients with shoulder pain, the percentage of patients who actually have MTrPs remains unclear. The aim of this observational study was to assess the prevalence of muscles with MTrPs and the association between MTrPs and the severity of pain and functioning in patients with chronic non-traumatic unilateral shoulder pain. Methods An observational study was conducted. Subjects were recruited from patients participating in a controlled trial studying the effectiveness of physical therapy on patients with unilateral non-traumatic shoulder pain. Sociodemographic and patient-reported symptom scores, including the Disabilities of the Arm, Shoulder, and Hand (DASH) Questionnaire, and Visual Analogue Scales for Pain were compared with other studies. To test for differences in age, gender distribution, and education level between the current study population and the populations from Dutch shoulder studies, the one sample T-test was used. One observer examined all subjects (n = 72) for the presence of MTrPs. Frequency distributions, means, medians, standard deviations, and 95% confidence intervals were calculated for descriptive purposes. The Spearman's rank-order correlation (ρ) was used to test for association between variables. Results MTrPs were identified in all subjects. The median number of muscles with MTrPs per subject was 6 (active MTrPs) and 4 (latent MTrPs). Active MTrPs were most prevalent in the infraspinatus (77%) and the upper trapezius muscles (58%), whereas latent MTrPs were most prevalent in the teres major (49%) and anterior deltoid muscles (38%). The number of muscles with active MTrPs was only moderately correlated with the DASH score. Conclusion The prevalence of muscles containing active and latent MTrPs in a sample of patients with chronic non-traumatic shoulder pain was high. PMID:21711512

Study Design Secondary analysis of prospectively collected data. Background An abundance of evidence has highlighted the influence of pain catastrophizing and fear avoidance on clinical outcomes. Less is known about the interaction of positive psychological resources with these pain-associated distress factors. Objective To assess whether optimism moderates the influence of pain catastrophizing and fear avoidance on 3-month clinical outcomes in patients with shoulder pain. Methods Data from 63 individuals with shoulder pain (mean ± SD age, 38.8 ± 14.9 years; 30 female) were examined. Demographic, psychological, and clinical characteristics were obtained at baseline. Validated measures were used to assess optimism (Life Orientation Test-Revised), pain catastrophizing (Pain Catastrophizing Scale), fear avoidance (Fear-Avoidance Beliefs Questionnaire physical activity subscale), shoulder pain intensity (Brief Pain Inventory), and shoulder function (Pennsylvania Shoulder Score function subscale). Shoulder pain and function were reassessed at 3 months. Regression models assessed the influence of (1) pain catastrophizing and optimism and (2) fear avoidance and optimism. The final multivariable models controlled for factors of age, sex, education, and baseline scores, and included 3-month pain intensity and function as separate dependent variables. Results Shoulder pain (mean difference, -1.6; 95% confidence interval [CI]: -2.1, -1.2) and function (mean difference, 2.4; 95% CI: 0.3, 4.4) improved over 3 months. In multivariable analyses, there was an interaction between pain catastrophizing and optimism (β = 0.19; 95% CI: 0.02, 0.35) for predicting 3-month shoulder function (F = 16.8, R 2 = 0.69, P<.001), but not pain (P = .213). Further examination of the interaction with the Johnson-Neyman technique showed that higher levels of optimism lessened the influence of pain catastrophizing on function. There was no evidence of significant moderation of fear-avoidance beliefs for 3-month shoulder pain (P = .090) or function (P = .092). Conclusion Optimism decreased the negative influence of pain catastrophizing on shoulder function, but not pain intensity. Optimism did not alter the influence of fear-avoidance beliefs on these outcomes. Level of Evidence Prognosis, level 2b. J Orthop Sports Phys Ther 2017;47(1):21-30.

Objectives To develop and validate a national set of best practice statements for use in post-stroke aphasia rehabilitation. Design Literature review and statement validation using the RAND/UCLA Appropriateness Method (RAM). Participants A national Community of Practice of over 250 speech pathologists, researchers, consumers and policymakers developed a framework consisting of eight areas of care in aphasia rehabilitation. This framework provided the structure for the development of a care pathway containing aphasia rehabilitation best practice statements. Nine speech pathologists with expertise in aphasia rehabilitation participated in two rounds of RAND/UCLA appropriateness ratings of the statements. Panellists consisted of researchers, service managers, clinicians and policymakers. Main outcome measures Statements that achieved a high level of agreement and an overall median score of 7–9 on a nine-point scale were rated as ‘appropriate’. Results 74 best practice statements were extracted from the literature and rated across eight areas of care (eg, receiving the right referrals, providing intervention). At the end of Round 1, 71 of the 74 statements were rated as appropriate, no statements were rated as inappropriate, and three statements were rated as uncertain. All 74 statements were then rated again in the face-to-face second round. 16 statements were added through splitting existing items or adding new statements.

To develop and validate a national set of best practice statements for use in post-stroke aphasia rehabilitation. Literature review and statement validation using the RAND/UCLA Appropriateness Method (RAM). A national Community of Practice of over 250 speech pathologists, researchers, consumers and policymakers developed a framework consisting of eight areas of care in aphasia rehabilitation. This framework provided the structure for the development of a care pathway containing aphasia rehabilitation best practice statements. Nine speech pathologists with expertise in aphasia rehabilitation participated in two rounds of RAND/UCLA appropriateness ratings of the statements. Panellists consisted of researchers, service managers, clinicians and policymakers. Statements that achieved a high level of agreement and an overall median score of 7-9 on a nine-point scale were rated as 'appropriate'. 74 best practice statements were extracted from the literature and rated across eight areas of care (eg, receiving the right referrals, providing intervention). At the end of Round 1, 71 of the 74 statements were rated as appropriate, no statements were rated as inappropriate, and three statements were rated as uncertain. All 74 statements were then rated again in the face-to-face second round. 16 statements were added through splitting existing items or adding new statements. Seven statements were deleted leaving 83 statements. Agreement was reached for 82 of the final 83 statements. This national set of 82 best practice statements across eight care areas for the rehabilitation of people with aphasia is the first to be validated by an expert panel. These statements form a crucial component of the Australian Aphasia Rehabilitation Pathway (AARP) (http://www.aphasiapathway.com.au) and provide the basis for more consistent implementation of evidence-based practice in stroke rehabilitation.

The treatment of young patients with glenohumeral arthritis has been challenging. Alternative treatment options include activity modification, arthroscopic débridement, and arthroplasty. Addressing the glenoid during arthroplasty in this population of patients continues to be a significant challenge. In this study, we evaluated the midterm outcomes of hemiarthroplasty with biologic resurfacing of the glenoid with human dermal matrix allograft. Between 2004 and 2011, 55 patients underwent hemiarthroplasty and biologic resurfacing of the glenoid with human dermal matrix allograft. The average age was 50 ± 9 years. Subjective evaluation was performed with the Western Ontario Osteoarthritis of the Shoulder Index, American Shoulder and Elbow Surgeons score, visual analog scale, and Single Assessment Numeric Evaluation. Patients returned to the clinic for clinical examination and radiographic evaluation. The average follow-up was 60 months. The average postoperative American Shoulder and Elbow Surgeons score was 76 ± 22, and the Western Ontario Osteoarthritis of the Shoulder Index score was 76% ± 22%. The visual analog scale score was 2.4 ± 2.6. The average preoperative Single Assessment Numeric Evaluation score was 33% ± 22%, which significantly improved to 72% ± 22% postoperatively. Eighty-one percent of the patients were satisfied (10/47) or highly satisfied (28/47) with their result. With radiographic evaluation, the average joint space was 1 ± 1 mm preoperatively and 2 ± 1 mm postoperatively. A total of 5 cases (9.1%) were revised to anatomic total shoulder arthroplasty with implantation of a glenoid component. Hemiarthroplasty with biologic resurfacing of the glenoid using human dermal matrix allograft can lead to successful midterm outcomes with satisfactory complication and revision rates. Both patient satisfaction and clinical outcome remain high regardless of radiographic outcome. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

To evaluate the feasibility of 3D fast spin-echo (FSE) imaging with compressed sensing (CS) for the assessment of shoulder. Twenty-nine patients who underwent shoulder MRI including image sets of axial 3D-FSE sequence without CS and with CS, using an acceleration factor of 1.5, were included. Quantitative assessment was performed by calculating the root mean square error (RMSE) and structural similarity index (SSIM). Two musculoskeletal radiologists compared image quality of 3D-FSE sequences without CS and with CS, and scored the qualitative agreement between sequences, using a five-point scale. Diagnostic agreement for pathologic shoulder lesions between the two sequences was evaluated. The acquisition time of 3D-FSE MRI was reduced using CS (3min 23s vs. 2min 22s). Quantitative evaluations showed a significant correlation between the two sequences (r=0.872-0.993, p<0.05) and SSIM was in an acceptable range (0.940-0.993; mean±standard deviation, 0.968±0.018). Qualitative image quality showed good to excellent agreement between 3D-FSE images without CS and with CS. Diagnostic agreement for pathologic shoulder lesions between the two sequences was very good (κ=0.915-1). The 3D-FSE sequence with CS is feasible in evaluating the shoulder joint with reduced scan time compared to 3D-FSE without CS. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective This study seeks to establish the efficacy of single-lead, 3-week peripheral nerve stimulation (PNS) therapy for pain reduction in stroke survivors with chronic hemiplegic shoulder pain. Design Single-site, pilot, randomized controlled trial for adults with chronic shoulder pain after stroke. Participants were randomized to receive a 3-week treatment of single-lead PNS or usual care (UC). The primary outcome was the worst pain in the last week (Brief Pain Inventory, Short Form question 3) measured at baseline, and weeks 1,4, 12, and 16. Secondary outcomes included pain interference (Brief Pain Inventory, Short Form question 9), pain measured by the ShoulderQ Visual Graphic Rating Scales; and health-related quality of life (SF-36v2). Results Twenty-five participants were recruited, 13 to PNS and 12 to UC. There was a significantly greater reduction in pain for the PNS group compared to controls, with significant differences at 6 and 12 weeks after treatment. Both PNS and UC were associated with significant improvements in pain interference and physical health related quality of life. Conclusions Short-term PNS is a safe and efficacious treatment for shoulder pain. Pain reduction is greater than compared to UC and is maintained for at least 12 weeks after treatment. PMID:24355994

Electron phase-space holes, regions of positive potential on the scale of the Debye length, have been observed in auroras as well as in laboratory experiments. These potential structures, also known as Time Domain Structures (TDS), are packets of intense electric field spikes that have significant components parallel to the local magnetic field. In an ongoing investigation at UCLA, TDS were observed on the surface of two magnetized flux ropes produced within the Large Plasma Device (LAPD). A barium oxide (BaO) cathode was used to produce an 18 m long magnetized plasma column and a lanthanum hexaboride (LaB6) source was used to create 11 m long kink unstable flux ropes. Using two probes capable of measuring the local electric and magnetic fields, correlation analysis was performed on tens of thousands of these structures and their propagation velocities, probability distribution function and spatial distribution were determined. The TDS became abundant as the flux ropes collided and appear to emanate from the reconnection region in between them. In addition, a preliminary analysis of the permutation entropy and statistical complexity of the data suggests that the TDS signals may be chaotic in nature.

One of the most significant challenges in large-scale climate modeling, as well as in high-performance computing in other scientific fields, is that of effectively integrating many software models from multiple contributors. A software framework facilitates the integration task. both in the development and runtime stages of the simulation. Effective software frameworks reduce the programming burden for the investigators, freeing them to focus more on the science and less on the parallel communication implementation, while maintaining high performance across numerous supercomputer and workstation architectures. This document proposes a strawman framework design for the climate community based on the integration of Cactus, from the relativistic physics community, and UCLA/UCB Distributed Data Broker (DDB) from the climate community. This design is the result of an extensive survey of climate models and frameworks in the climate community as well as frameworks from many other scientific communities. The design addresses fundamental development and runtime needs using Cactus, a framework with interfaces for FORTRAN and C-based languages, and high-performance model communication needs using DDB. This document also specifically explores object-oriented design issues in the context of climate modeling as well as climate modeling issues in terms of object-oriented design.

Purpose The pain experience has multiple influences but little is known about how specific biological and psychological factors interact to influence pain responses. The current study investigated the combined influences of genetic (pro-inflammatory) and psychological factors on several pre-clinical shoulder pain phenotypes. Methods An exercise-induced shoulder injury model was used, and a priori selected genetic (IL1B, TNF/LTA region, IL6 single nucleotide polymorphisms, SNPs) and psychological (anxiety, depressive symptoms, pain catastrophizing, fear of pain, kinesiophobia) factors were included as the predictors of interest. The phenotypes were pain intensity (5-day average and peak reported on numerical rating scale), upper-extremity disability (5-day average and peak reported on the QuickDASH instrument), and duration of shoulder pain (in days). Results After controlling for age, sex, and race, the genetic and psychological predictors were entered separately as main effects and interaction terms in regression models for each pain phenotype. Results from the recruited cohort (n = 190) indicated strong statistical evidence for the interactions between 1) TNF/LTA SNP rs2229094 and depressive symptoms for average pain intensity and duration and 2) IL1B two-SNP diplotype and kinesiophobia for average shoulder pain intensity. Moderate statistical evidence for prediction of additional shoulder pain phenotypes included interactions of kinesiophobia, fear of pain, or depressive symptoms with TNF/LTA rs2229094 and IL1B. Conclusion These findings support the combined predictive ability of specific genetic and psychological factors for shoulder pain phenotypes by revealing novel combinations that may merit further investigation in clinical cohorts, to determine their involvement in the transition from acute to chronic pain conditions.

Despite the fact that the number of disabled individuals participating in sports is increasing, there are only sparse reports in the literature concerning overuse injuries. The purpose of this study was to compare scapular resting position, shoulder pain, and function in wheelchair basketball, amputee soccer, and disabled table tennis players. Descriptive study. A total of 63 disabled players from amputee soccer, wheelchair basketball, and disabled table tennis participated in our study. Scapular resting position was taken as primary outcome; pain and function were taken as secondary outcome measurements. Scapular resting position was evaluated with Lateral Scapular Slide Test. Visual Analog Scale was used for evaluating shoulder pain intensity. Quick disabilities of the arm, shoulder, and hand questionnaire were used to assess upper extremity function. There was a significant difference in shoulder pain, function, and scapular resting position in all groups (p < 0.05). Paired comparisons between amputee soccer and wheelchair basketball players and also amputee soccer and disabled table tennis showed difference for all measurement parameters (p < 0.05). When the results are evaluated, it may be stated that amputee soccer players have better scapular resting position than other sports. Crutch usage may not negatively affect scapular resting position and perceived function as much as wheelchair usage. Exercise techniques for shoulder and resting position could be included in training programs of disabled athletes. Wheelchair/crutch usage is a risk, and special exercise techniques for shoulder and dyskinesis could be included in training programs to prevent injury. However, it may not just be important for wheelchair athletes, it may also be important for amputee soccer players. In particular, total upper extremity evaluations and exercises could be added within exercise programs. © The International Society for Prosthetics and Orthotics 2014.

Conservative management for uncomplicated displaced clavicle fractures is common practice. Delay of surgical fixation may result in less favorable outcomes. A retrospective cohort study was conducted of 60 patients with a closed mid-third clavicle fracture that did not meet current operative or nonoperative guidelines; 20 primary (plate fixation <6 weeks), 20 delayed (plate fixation >6 weeks), and 20 matched conservative patients were included. Each patient completed 2 questionnaires, the Disabilities of the Arm, Shoulder, and Hand and the American Shoulder and Elbow Surgeons, as well as visual analog scales for pain, cosmetic satisfaction, and overall satisfaction. In addition, 10 patients from each group underwent clinical review of scapular rotation by the lateral scapular slide test, clinical impingement, range of motion assessment, and radiologic review of clavicle union and length. The American Shoulder and Elbow Surgeons patient self-reported questionnaire demonstrated a median score of 5.5 for the delayed group, 2 for the primary group, and 1 for the conservative group (P = .032). The median Disabilities of the Arm, Shoulder, and Hand score was 7.92 for the delayed group, 3.32 for the primary group, and 1.67 for the conservative group (P = .212). Six patients in the delayed group had scapular malrotation compared with 2 in the primary group and none in the conservative group (P = .008). Flexion and external rotation in 90° abduction were decreased in the conservative group (P = .049 and .041, respectively). We support the conservative management of uncomplicated displaced clavicle fractures but recognize that a lower threshold for early surgery should be considered where optimal shoulder function is required.

Retear and stiffness are not uncommon outcomes of rotator cuff repair. The purpose of this study was to evaluate the relationship between rotator cuff repair healing and shoulder stiffness. A total of 1,533 consecutive shoulders had an arthroscopic rotator cuff repair by a single surgeon. Patients assessed their shoulder stiffness using a Likert scale preoperatively and at 1, 6, 12, and 24 weeks (6 months) postoperatively, and examiners evaluated passive range of motion preoperatively and at 6, 12, and 24 weeks postoperatively. Repair integrity was determined by ultrasound evaluation at 6 months. After rotator cuff repair, there was an overall significant loss of patient-ranked and examiner-assessed shoulder motion at 6 weeks compared with preoperative measurements (p < 0.0001), a partial recovery at 12 weeks, and a full recovery at 24 weeks. Shoulders that were stiff before surgery were more likely to be stiff at 6, 12, and, to a lesser extent, 24 weeks after surgery (r = 0.10 to 0.31; p < 0.0001). A stiffer shoulder at 6 and 12 weeks (but not 24 weeks) postoperatively correlated with better rotator cuff integrity at 6 months postoperatively (r = 0.11 to 0.18; p < 0.001). The retear rate of patients with ≤20° of external rotation at 6 weeks postoperatively was 7%, while the retear rate of patients with >20° of external rotation at 6 weeks was 15% (p < 0.001). In patients who developed stiffness after surgery, a rotator cuff repair was more likely to heal. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The purpose of this preliminary study was to investigate changes in shoulder pain, disability, and perceived level of recovery after 2 sessions of upper thoracic and upper rib high-velocity low-amplitude (HVLA) thrust manipulation in patients with shoulder pain secondary to second and third rib syndrome. This exploratory study evaluated 10 consecutive individuals with shoulder pain, with or without brachial pain, and a negative Neer impingement test, who completed the Shoulder Pain and Disability Index (SPADI), the numeric pain rating scale (NPRS), and the global rating of change. Patients received 2 sessions of HVLA thrust manipulation targeting the upper thoracic spine bilaterally and the second and third ribs on the symptomatic side. Outcome measures were completed after the first treatment session, at 48 hours, 1 month, and 3 months. Patients showed a significant decrease in SPADI (F = 59.997; P = .001) and significant decrease in resting shoulder NPRS (F = 63.439; P = .001). For both NPRS and SPADI, there were significant differences between the pretreatment scores and each of the postintervention scores through 3-month follow-up (P < .05). Large within-group effect sizes (Cohen's d ≥ 0.8) were found between preintervention data and all postintervention assessments in both outcomes. Mean global rating of change scores (+6.8 at 3 months) indicated "a very great deal better" outcome at long-term follow-up. This group of patients with shoulder pain secondary to second and third rib syndrome who received upper thoracic and upper rib HVLA thrust manipulations showed significant reductions in pain and disability and improvement in perceived level of recovery.

Predicting vulnerability to hopelessness. A longitudinal analysis.

PubMed

Bonner, R L; Rich, A R

1991-01-01

The role of loneliness, irrational beliefs, and deficient reasons for living in predicting vulnerability to hopelessness under conditions of negative life stress was examined. Subjects (N = 178) completed the UCLA Loneliness Scale. Rational Beliefs Inventory, and the Reasons for Living Inventory at the beginning of the semester. Then, at midterm, measures of negative life stress, depression, and hopelessness were obtained from the same subjects. It was hypothesized that the vulnerability factors would interact with negative life stress to predict hopelessness, independent of depressed mood. The results of multiple regression analyses supported this hypothesis. Implications for research, prevention, and treatment are noted.

This cross-sectional study analyzed the influence of chronic shoulder pain (CSP) on movement variability/kinematics during humeral elevation, with the trunk and elbow motions constrained to avoid compensatory strategies. For this purpose, 37 volunteers with CSP as the injured group (IG) and 58 participants with asymptomatic shoulders as the control group (CG) participated in the study. Maximum humeral elevation (Emax), maximum angular velocity (Velmax), variability of the maximum angle (CVEmax), functional variability (Func_var), and approximate entropy (ApEn) were calculated from the kinematic data. Patients' pain was measured on the visual analogue scale (VAS). Compared with the CG, the IG presented lower Emax and Velmax and higher variability (i.e., CVEmax, Func_var, and ApEn). Moderate correlations were achieved for the VAS score and the kinematic variables Emax, Velmax and variability of curve analysis, Func_varm, and ApEn. No significant correlation was found for CVEmax. In conclusion, CSP results in a decrease of angle and velocity and an increased shoulder movement variability when the neuromuscular system cannot use compensatory strategies to avoid painful positions.

Coracoid syndrome: a neglected cause of anterior shoulder pain.

PubMed

Gigante, Antonio; Bottegoni, Carlo; Barbadoro, Pamela

2016-01-01

the present prospective open-label study was designed to gain further insights into a condition thought to constitute a neglected but not uncommon syndrome characterized by anterior shoulder pain and tenderness to palpation over the apex of the coracoid process, not related to rotator cuff or pectoralis minor tendinopathy, long head of the biceps tendon disorders, or instability. The aim was to clarify its prevalence, clinical characteristics, differential diagnosis and response to corticosteroid injections. patients with primary anterior shoulder pain precisely reproduced by deep pressure on the apex of the coracoid process were recruited. Patients with clinical or instrumental signs of other shoulder disorders were excluded. Patients were given an injection of triamcinolone acetonide 40 mg/ml 1 ml at the coracoid trigger point. They were evaluated after 15, 30 and 60 days and at 2 years using Equal Visual Analog Scale (EQ-VAS) and the Italian version of the Simple Shoulder Test (SST). between January 1 and December 31 2010, we treated 15 patients aged 26-66 years. The majority were women (86.67%). At 15 days, 6 (40%) patients reported complete resolution of their symptoms, while 9 (60%) complained of residual symptoms and received another injection. At 30 days, 14 (93.33%) patients were pain-free and very satisfied. At 2 years, the 14 patients who had been asymptomatic at 30 days reported that they had experienced no further pain or impaired shoulder function. The analysis of variance for repeated measures showed a significant effect of time on EQ-VAS and SST scores. the present study documents the existence, and characteristics, of a "coracoid syndrome" characterized by anterior shoulder pain and tenderness to palpation over the apex of the coracoid process and showed that the pain is usually amenable to steroid treatment. This syndrome should be clearly distinguished from anterior shoulder pain due to other causes, in order to avoid inappropriate conservative or surgical treatment. Level IV, therapeutic case series.

Specific strength training can reduce neck and shoulder pain in office workers, but the optimal combination of exercise frequency and duration remains unknown. This study investigates how one weekly hour of strength training for the neck and shoulder muscles is most effectively distributed. A total of 447 office workers with and without neck and/or shoulder pain were randomly allocated at the cluster-level to one of four groups; 1×60 (1WS), 3×20 (3WS) or 9×7 (9WS) min a week of supervised high-intensity strength training for 20 weeks, or to a reference group without training (REF). Primary outcome was self-reported neck and shoulder pain (scale 0-9) and secondary outcome work disability (Disability in Arms, Shoulders and Hands (DASH)). The intention-to-treat analysis showed reduced neck and right shoulder pain in the training groups after 20 weeks compared with REF. Among those with pain ≥3 at baseline (n=256), all three training groups achieved significant reduction in neck pain compared with REF (p<0.01). From a baseline pain rating of 3.2 (SD 2.3) in the neck among neck cases, 1WS experienced a reduction of 1.14 (95% CI 0.17 to 2.10), 3WS 1.88 (0.90 to 2.87) and 9WS 1.35 (0.24 to 2.46) which is considered clinically significant. DASH was reduced in 1WS and 3WS only. One hour of specific strength training effectively reduced neck and shoulder pain in office workers. Although the three contrasting training groups showed no statistical differences in neck pain reduction, only 1WS and 3WS reduced DASH. This study suggests some flexibility regarding time-wise distribution when implementing specific strength training at the workplace.

To evaluate how transfer technique and subject characteristics relate to ultrasound measures of shoulder soft tissue pathology and self-reported shoulder pain during transfers in a sample of wheelchair users with spinal cord injury (SCI). Cross-sectional observational study. Research laboratory, national and local veterans' wheelchair sporting events. A convenience sample of wheelchair users (N=76) with nonprogressive SCI. Participants were aged >18 years, >1 year postinjury, and could complete repeated independent wheelchair transfers without the use of their leg muscles. Not applicable. Transfer pain items from the Wheelchair User's Shoulder Pain Index; transfer technique assessed using the Transfer Assessment Instrument (TAI); and shoulder pathology markers examined using the Ultrasound Shoulder Pathology Rating Scale (USPRS). Better transfer technique (higher TAI) correlated with less injury (lower USPRS) (partial η(2)=.062, P<.05) and less pain during transfers (partial η(2)=.049, P<.10). Greater age was the strongest predictor of greater pathology (USPRS total: partial η(2)=.225, supraspinatus grade: partial η(2)=.174, P<.01). An interaction between technique and weight was found (P<.10): participants with lower body weights showed a decrease in pathology markers with better transfer technique (low weight: R(2)=.422, P<.05; middle weight: R(2)=.200, P<.01), while those with higher weight showed little change with technique (R(2)=.018, P>.05). Participants with better transfer technique exhibited less shoulder pathology and reported less pain during transfers. The relationship between technique and pathology was strongest in lower-weight participants. While causation cannot be proven because of study design, it is possible that using a better transfer technique and optimizing body weight could reduce the incidence of shoulder pathology and pain.

Intervention randomized controlled trials involving wrist and shoulder arthroscopy: a systematic review

PubMed Central

2014-01-01

Background Although arthroscopy of upper extremity joints was initially a diagnostic tool, it is increasingly used for therapeutic interventions. Randomized controlled trials (RCTs) are considered the gold standard for assessing treatment efficacy. We aimed to review the literature for intervention RCTs involving wrist and shoulder arthroscopy. Methods We performed a systematic review for RCTs in which at least one arm was an intervention performed through wrist arthroscopy or shoulder arthroscopy. PubMed and Cochrane Library databases were searched up to December 2012. Two researchers reviewed each article and recorded the condition treated, randomization method, number of randomized participants, time of randomization, outcomes measures, blinding, and description of dropouts and withdrawals. We used the modified Jadad scale that considers the randomization method, blinding, and dropouts/withdrawals; score 0 (lowest quality) to 5 (highest quality). The scores for the wrist and shoulder RCTs were compared with the Mann–Whitney test. Results The first references to both wrist and shoulder arthroscopy appeared in the late 1970s. The search found 4 wrist arthroscopy intervention RCTs (Kienböck’s disease, dorsal wrist ganglia, volar wrist ganglia, and distal radius fracture; first 3 compared arthroscopic with open surgery). The median number of participants was 45. The search found 50 shoulder arthroscopy intervention RCTs (rotator cuff tears 22, instability 14, impingement 9, and other conditions 5). Of these, 31 compared different arthroscopic treatments, 12 compared arthroscopic with open treatment, and 7 compared arthroscopic with nonoperative treatment. The median number of participants was 60. The median modified Jadad score for the wrist RCTs was 0.5 (range 0–1) and for the shoulder RCTs 3.0 (range 0–5) (p = 0.012). Conclusion Despite the increasing use of wrist arthroscopy in the treatment of various wrist disorders the efficacy of arthroscopically performed wrist interventions has been studied in only 4 randomized studies compared to 50 randomized studies of significantly higher quality assessing interventions performed through shoulder arthroscopy.

To determine the efficacy of prolotherapy for refractory rotator cuff disease. Retrospective case-control study. University-affiliated tertiary care hospital. Patients with nontraumatic refractory rotator cuff disease (N=151) who were unresponsive to 3 months of aggressive conservative treatment. Of the patients, 63 received prolotherapies with 16.5% dextrose 10-ml solution (treatment group), and 63 continued conservative treatment (control group). Not applicable. Visual analog scale (VAS) score of the average shoulder pain level for the past 1 week, Shoulder Pain and Disability Index (SPADI) score, isometric strength of the shoulder abductor, active range of motion (AROM) of the shoulder, maximal tear size on ultrasonography, and number of analgesic ingestions per day. Over 1-year follow-up, 57 patients in the treatment group and 53 in the control group were analyzed. There was no significant difference between the 2 groups in age, sex, shoulder dominance, duration of symptoms, and ultrasonographic findings at pretreatment. The average number of injections in the treatment group is 4.8±1.3. Compared with the control group, VAS score, SPADI score, isometric strength of shoulder abductor, and shoulder AROM of flexion, abduction, and external rotation showed significant improvement in the treatment group. There were no adverse events. To our knowledge, this is the first study to assess the efficacy of prolotherapy in rotator cuff disease. Prolotherapy showed improvement in pain, disability, isometric strength, and shoulder AROM in patients with refractory chronic rotator cuff disease. The results suggest positive outcomes, but one should still take caution in directly interpreting it as an effective treatment option, considering the limitations of this nonrandomized retrospective study. To show the efficacy of prolotherapy, further studies on prospective randomized controlled trials will be required. Copyright © 2015 American Congress of Rehabilitation Medicine.

2014-12-01

Transfer of the latissimus dorsi tendon to the posterosuperior part of the rotator cuff is an option in active patients with massive rotator cuff tears to restore shoulder elevation and external rotation. However, it is unknown whether this treatment prevents progression of cuff tear arthropathy. The purpose of this study was to determine whether the observed improvement in shoulder function in the early postoperative period with latissimus dorsi tendon transfer for irreparable rotator cuff tears will be permanent or will deteriorate in the midterm period (at 1-5 years after surgery). During a 6-year period, we performed 11 latissimus dorsi tendon transfers in 11 patients for patients with massive, irreparable, chronic tears of the posterosuperior part of the rotator cuff (defined as > 5 cm supraspinatus and infraspinatus tendon tears with Goutallier Grade 3 to 4 fatty infiltration on MRI), for patients who were younger than 65 years of age, and had high functional demands and intact subscapularis function. No patients were lost to followup; minimum followup was 12 months (median, 33 months; range, 12-62 months). The mean patient age was 55 years (median, 53 years; range, 47-65 years). Shoulder forward elevation, external rotation, and Constant-Murley and American Shoulder and Elbow Surgeons scores were assessed. Pain was assessed by a 0- to 10-point visual analog scale. Acromiohumeral distance and cuff tear arthropathy (staged according to the Hamada classification) were evaluated on radiographs. Shoulder forward elevation, external rotation, Constant-Murley scores, and American Shoulder and Elbow Surgeons scores improved at 6 months. However, although shoulder motion values and Constant-Murley scores remained unchanged between the 6-month and latest evaluations, American Shoulder and Elbow Surgeons scores decreased in this period (median, 71; range, 33-88 versus median, 68; range, 33-85; p = 0.009). Visual analog scale scores improved between the preoperative and 6-month evaluations but then worsened (representing worse pain) between the 6-month and latest evaluations (median, 2; range, 0-5 versus median, 2; range, 1-6; p = 0.034), but scores at latest followup were still lower than preoperative values (median, 7; range, 4-8; p = 0.003). Although acromiohumeral distance values were increased at 6 months (median, 8 mm; range, 6-10 mm; p = 0.023), the values at latest followup (median, 8 mm; range, 5-10 mm) were no different from the preoperative ones (mean, 7 mm; range, 6-9 mm; p > 0.05). According to Hamada classification, all patients were Grade 1 both pre- and postoperatively, except one who was Grade 3 at latest followup. The latissimus dorsi tendon transfer may improve shoulder function in irreparable massive rotator cuff tears. However, because the tenodesis effect loses its strength with time, progression of the arthropathy should be expected over time. Nevertheless, latissimus dorsi tendon transfer may help to delay the need for reverse shoulder arthroplasty for these patients. Level IV, therapeutic study.

We present first results of the UCLA-LANL Reanalysis Project. Radiation belt relativistic electron Phase Space Density is obtained using the data assimilative VERB code combined with observations from GEO, CRRES, and Akebono data. Reanalysis of data shows the pronounced peaks in the phase space density and pronounced dropouts of fluxes during the main phase of a storm. The results of the reanalysis are discussed and compared to the simulations with the recently developed VERB 3D code.

Leon Knopoff died at his home in Sherman Oaks, Calif., on 20 January 2011 at the age of 85. A man of wide-ranging talents, he had the rare distinction of being simultaneously a professor of physics, a professor of geophysics, and a research musicologist at the University of California, Los Angeles (UCLA). As an undergraduate he studied electrical engineering and obtained his Ph.D. in physics and mathematics at the California Institute of Technology (Caltech) in 1949. He was recruited to the Institute of Geophysics (now the Institute of Geophysics and Planetary Physics) at UCLA in 1950 by Louis Slichter, where he became a professor of geophysics in 1957 and of geophysics and physics in 1961. He became a research musicologist in the UCLA Institute of Ethnomusicology soon after it was formed in 1960. Other appointments included faculty positions at Miami University in Ohio (1948-1950) and Caltech (1962-1963) and visiting appointments at Cambridge, Karlsruhe, Harvard, Santiago, Trieste, and Venice.

To report general life and health satisfaction after arthroscopic Bankart repair in patients with post-traumatic recurrent anterior glenohumeral instability and to investigate postoperative time lost to return to work at 2-year follow-up. Between 2011 and 2013 patients treated with arthroscopic Bankart repair in the beach chair position for acute shoulder instability were included in this study. Questions on Life Satisfaction Modules (FLZ M ) and the Short Form 12 (SF-12) were used as quality-of-life outcome scales. Oxford Instability Score (OIS), Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), and self-reported American Shoulder and Elbow Surgeons (ASES) shoulder index were used as functional outcome scales. Return to work (months) was monitored and analyzed depending on physical workload. Data were assessed the day before surgery and prospectively monitored until 24 months postoperatively. Quality-of-life outcome was correlated with functional shoulder outcome and compared with normative age-adjusted data. Paired t-test, Wilcoxon test, Mann-Whitney U-Test, and Spearman's correlation coefficient were used for statistical analysis. Fifty-three patients were prospectively included. The mean age at surgery was 29.4 years. Satisfaction with general life and satisfaction with health (FLZ M ) as well as physical component scale (SF-12) improved significantly to values above normative data within 6 to 12 months after surgery (each P < .001). OIS, QuickDASH, and ASES improved significantly from baseline until 24 months after surgery (each P < .001). For ASES, improvement above minimal clinically important difference was shown. There was a positive correlation between quality of life and functional outcome scores (P < .05; rho, 0.3-0.4). Mean time to return to work was 2 months (range, 0-10; standard deviation, 1.9), with significantly longer time intervals observed in patients with heavy physical workload (3.1 months; range, 0 to 10; standard deviation, 2.4; P = .002). Following arthroscopic Bankart repair, quality of life was impaired during early course after surgery and increased significantly above preoperative levels within 6 to 12 months after the procedure. A steady state of excellent quality-of-life and functional outcomes was noted after 12 months of follow-up. Quality-of-life outcome scales correlated significantly with the functional outcome. Heavy physical workload must be considered as a risk factor for prolonged time lost to return to work. Level III, prospective noncomparative therapeutic case series.

A planetary boundary layer (PBL) model is presented which employs a mixed layer entrainment formulation to describe the mass exchange between the mixed layer with the upper, laminar atmosphere. A modified coordinate system couples the mixed layer model with large scale and sub-grid scale processes of a general circulation model. The vertical coordinate is configured as a sigma coordinate with the lower boundary, the top of the PBL, and the prescribed pressure level near the tropopause expressed as coordinate surfaces. The entrainment mass flux is parameterized by assuming the dissipation rate of turbulent kinetic energy to be proportional to the positive part of the generation by convection or mechanical production. The results of a simulation of July are presented for the entire globe.

To identify the ability of the Persian-version of the Shoulder Pain and Disability Index (SPADI) and the Disabilities of the Arm, Shoulder, and Hand (DASH) to detect changes in shoulder function following physiotherapy intervention (i.e. responsiveness) and to determine the change score that indicates a meaningful change in functional ability of the patient (i.e. Minimally Clinically Important Difference (MCID)). A convenient sample of 200 Persian-speaking patients with shoulder disorders completed the SPADI and the DASH at baseline and then again 4 weeks after physiotherapy intervention. Furthermore, patients were asked to rate their global rating of shoulder function at follow-up. The responsiveness was evaluated using two methods: the receiver operating characteristics (ROC) method and the correlation analysis. Two useful statistics extracted from the ROC method are the area under curve (AUC) and the optimal cutoff point called as MCID. Both the SPADI and the DASH showed the AUC of greater than 0.70 (AUC ranges = 0.77-0.82). The best cutoff points (or change scores) for the SPADI-total, SPADI-pain, SPADI-disability and the DASH were 14.88, 26.36, 23.86, and 25.41, respectively. Additionally, moderate to good correlations (Gamma = -0.51 to -0.58) were found between the changes in SPADI/DASH and changes in global rating scale. The Persian SPADI and DASH have adequate responsiveness to clinical changes in patients with shoulder disorders. Moreover, the MCIDs obtained in this study will help the clinicians and researchers to determine if a Persian-speaking patient with shoulder disorder has experienced a true change following a physiotherapy intervention. Implications for Rehabilitation Responsiveness was evaluated using two methods; the receiver operating characteristics (ROC) method and the correlation analysis. The Persian SPADI and DASH can be used as two responsive instruments in both clinical practice and research settings. The MCIDs of 14.88 and 25.41 points obtained for the SPADI-total and DASH indicated that the change scores of at least 14.88 points on the SPADI-total and 25.41 points on the DASH is necessary to certain that a true change has occurred following a physiotherapy intervention.

Social connections are essential for the survival of a social species like humans. People differ in the degree to which they are sensitive to perceived deficits in their social connections, but evidence suggests that they nevertheless construe the nature of their social connections similarly. This construal can be thought of as a mental representation of a multi-faceted social experience. A three-dimensional mental representation has been identified with the UCLA Loneliness Scale and consists of Intimate, Relational, and Collective Connectedness reflecting beliefs about one's individual, dyadic, and collective (group) social value, respectively. Moreover, this mental representation has been replicated with other scales and validated across age, gender, and racial/ethnic lines in U.S. samples. The purpose of this study is to evaluate the extent to which this three-dimensional representation applies to people whose social lives are experienced in a collectivistic rather than individualistic culture. To that end, we used confirmatory factor analyses to assess the fit of the three-dimensional mental structure to data collected from Chinese people living in China. Two hundred sixty-seven young adults (16–25 yrs) and 250 older adults (50–65 yrs) in Beijing completed the revised UCLA Loneliness Scale and demographic and social activity questionnaires. Results revealed adequate fit of the structure to data from young and older Chinese adults. Moreover, the structure exhibited equivalent fit in young and older Chinese adults despite changes in the Chinese culture that exposed these two generations to different cultural experiences. Social activity variables that discriminated among the three dimensions in the Chinese samples corresponded well with variables that discriminated among the three dimensions in the U.S.-based samples, indicating cultural commonalities in the factors predicting dimensions of people's representations of their social connections. Equivalence of the three-dimensional structure is relevant for an understanding of cultural differences in the sources of loneliness and social connectedness. PMID:23028486

Psoriasis and leg ulcers have a marked impact on the patient's quality of life and represent a life-long burden for affected patients. The aim of this study is to compare the quality of life, anxiety and depression, self-esteem, and loneliness in patients with psoriasis and leg-ulcer patients. Eighty patients with leg ulcers, eighty patients with psoriasis, and eighty healthy controls were included in this study. The quality of life, depression and anxiety, loneliness of the patient, and self-esteem were assessed using the Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), the UCLA loneliness Scale (UCLA-Version 3), and the Rosenberg's Self-esteem Scale (RSES), respectively. The DLQI score among patients with psoriasis was 12.74 ± 4.89 and leg ulcer patients was 13.28 ± 2.57. The patients with psoriasis presented statistically significant higher anxiety (9.87 ± 4.56) than both leg ulcer patients (8.26 ± 2.82) and controls (6.45 ± 1.89), while leg ulcer patients also presented higher anxiety than controls. Regarding self-esteem, although there were no significant differences between the patients with psoriasis (15.25 ± 3.20) and the ones with leg ulcers (15.89 ± 2.93), they both presented statistically significant lower self-esteem scores than control group (18.53 ± 3.04). The patients with psoriasis presented statistically significant higher levels of loneliness and social isolation (46.18 ± 6.63) compared to leg ulcer patients (43.73 ± 5.68) than controls (42.49 ± 3.41). Psoriasis and leg ulcers are long-term skin diseases associated with significant impairment of the patient's quality of life, anxiety, and self-esteem, which are frequently under-recognized. © 2016 by the Wound Healing Society.

This study was undertaken to assess the reliability of the posterior approach under ultrasonographic guidance (PAUGA), with the arm abducted, before performing direct magnetic resonance (MR) arthrography of the shoulder. A total of 111 (82 men, 29 women; mean age, 24 years) underwent direct MR arthrography of the shoulder. Patients were enrolled because of glenohumeral instability (n=71), chronic shoulder pain (n=25), suspicion of rotator cuff tear (n=13) and adhesive capsulitis (n=2). Patients were placed in the lateral position, on the contralateral side to that being examined; the arm of the shoulder undergoing the examination was placed in slight internal rotation with the hand under the contralateral armpit. A gadolinium-based solution was injected into the articular capsule under cryoanaesthesia and sonographic guidance. A posterior approach was systematically applied. For each patient, the number of injection attempts, room time, complications and pain, as recorded on a 10-point visual analogue scale (VAS), were noted. For quantitative parameters (room time and pain intensity), the mean and standard deviation (SD) were calculated. Direct MR arthrographies were performed successfully in all patients; no immediate or late major complications were observed. Fourteen patients (12.6%) reported temporary and self-limiting compromise of arm movements, and 13 patients (11.7%) reported a vagal reaction not requiring medication. In 102 cases (92%), the injection was successful at the first attempt, whereas in the remaining nine cases (8%), needle repositioning without any additional puncture was required to obtain clear sonographic depiction of the position of the needle tip. Mean room time was 7.2±1.4 min. Mean pain intensity was 3.2±0.4 on the 10-point VAS scale. PAUGA is a reliable and rapid technique that is well tolerated by patients and easy for the radiologist to perform.

The prevalence of musculoskeletal pain in the shoulder, arm and hand is high among slaughterhouse workers, allegedly due to the highly repetitive and forceful exposure of these body regions during work. Work disability is a common consequence of these pains. Lowering the physical exposure through ergonomics intervention is the traditional strategy to reduce the workload. An alternative strategy could be to increase physical capacity of the worker through strength training. This study investigates the effect of two contrasting interventions, participatory ergonomics versus strength training on pain and work disability in slaughterhouse workers with chronic pain. 66 slaughterhouse workers were allocated to 10 weeks of (1) strength training of the shoulder, arm and hand muscles for 3 x 10 minutes per week, or (2) participatory ergonomics involving counseling on workstation adjustment and optimal use of work tools (~usual care control group). Inclusion criteria were (1) working at a slaughterhouse for at least 30 hours per week, (2) pain intensity in the shoulder, elbow/forearm, or hand/wrist of at least 3 on a 0-10 VAS scale during the last three months, (3) pain lasting for more than 3 months, (4) frequent pain (at least 3 days per week) (5) at least moderate work disability, (6) no strength training during the last year, (7) no ergonomics instruction during the last year.Perceived pain intensity (VAS scale 0-10) of the shoulder, elbow/forearm and hand/wrist (primary outcome) and Disability of the Arm, Shoulder and Hand (Work module, DASH questionnaire) were measured at baseline and 10-week follow-up. Further, total muscle tenderness score and muscle function were assessed during clinical examination at baseline and follow-up. This RCT study will provide experimental evidence of the effectiveness of contrasting work-site interventions aiming at reducing chronic pain and work disability among employees engaged in repetitive and forceful work.

The UCLA-DOE Institute of Genomics and Proteomics is an organized research unit of the University of California, sponsored by the Department of Energy through the mechanism of a Cooperative Agreement. Today the Institute consists of 10 Principal Investigators and 7 Associate Members, developing and applying technologies to promote the biological and environmental missions of the Department of Energy, and 5 Core Technology Centers to sustain this work. The focus is on understanding genomes, pathways and molecular machines in organisms of interest to DOE, with special emphasis on developing enabling technologies. Since it was founded in 1947, the UCLA-DOE Institute hasmore » adapted its mission to the research needs of DOE and its progenitor agencies as these research needs have changed. The Institute started as the AEC Laboratory of Nuclear Medicine, directed by Stafford Warren, who later became the founding Dean of the UCLA School of Medicine. In this sense, the entire UCLA medical center grew out of the precursor of our Institute. In 1963, the mission of the Institute was expanded into environmental studies by Director Ray Lunt. I became the third director in 1993, and in close consultation with David Galas and John Wooley of DOE, shifted the mission of the Institute towards genomics and proteomics. Since 1993, the Principal Investigators and Core Technology Centers are entirely new, and the Institute has separated from its former division concerned with PET imaging. The UCLA-DOE Institute shares the space of Boyer Hall with the Molecular Biology Institute, and assumes responsibility for the operation of the main core facilities. Fig. 1 gives the organizational chart of the Institute. Some of the benefits to the public of research carried out at the UCLA-DOE Institute include the following: The development of publicly accessible, web-based databases, including the Database of Protein Interactions, and the ProLinks database of genomicly inferred protein function linkages. The development of publicly accessible, web-based servers, including the HOTPATCH server, the ProKnow Server and the SAVEs server. All of these are accessible from the home page of the Institute.

The impact of electronic health records (EHRs) and their effects on optimizing the patient experience has been debated nationally. Currently, there is a paucity of data in this area, and existing research offers conflicting results. Since 2006, the Assessing Residents' CI-CARE (ARC) program has evaluated the physician-patient interaction of resident physicians at University of California, Los Angeles (UCLA) Health utilizing a 20-item questionnaire administered through facilitator-patient interviews. To evaluate the impact of EHR implementation on the patient experience. Retrospective cohort study. Two academic medical campuses: Ronald Reagan UCLA Medical Center and UCLA Medical Center, Santa Monica. A total of 3417 surveys, spanning December 1, 2012 to May 30, 2013, were assessed. This included patient representation from 9 departments within UCLA Health. Surveys were analyzed to assess physician-patient communication. Statistical comparisons were made using χ analysis. All 16 questions assessing physician-patient communication received better responses in the 3 months following EHR implementation, compared to the 3 months prior to implementation. Of these, 9 questions illustrated statistically significant improvement, whereas the improvement in the remaining 7 questions was not statistically significant. These results suggest that EHRs may improve physician-patient communication. The ARC infrastructure allowed for observation of this trend; however, future research should aim to further validate and understand the etiologies of this improvement. © 2014 Society of Hospital Medicine.

Loneliness and Schizotypy Are Distinct Constructs, Separate from General Psychopathology.

Loneliness is common in youth and associated with a significantly increased risk of psychological disorders. Although loneliness is strongly associated with psychosis, its relationship with psychosis proneness is unclear. Our aim in this paper was to test the hypothesis that loneliness and schizotypal traits, conveying risk for schizophrenia spectrum disorders, are similar but separate constructs. Pooling data from two non-clinical student samples (N = 551) we modeled the structure of the relationship between loneliness and trait schizotypy. Loneliness was assessed with the University of California, Los Angeles Loneliness Scale (UCLA-3), whilst negative (Social Anhedonia) and positive (Perceptual Aberrations) schizotypal traits were assessed with the Wisconsin Schizotypy Scales-Brief (WSS-B). Fit statistics indicated that the best fitting model of UCLA-3 scores comprises three correlated factors (Isolation, Related Connectedness, and Collective Connectedness), consistent with previous reports. Fit statistics for a two factor model of positive and negative schizotypy were excellent. Next, bi-factor analysis was used to model a general psychopatholgy factor (p) across the three loneliness factors and separate negative and positive schizotypy traits. The results showed that all items (except 1) co-loaded on p. However, with the influence of p removed, additional variance remained within separate sub-factors, indicating that loneliness and negative and positive trait schizotypy are distinct and separable constructs. Similarly, once shared variance with p was removed, correlations between sub-factors of loneliness and schizotypal traits were non-significant. These findings have important clinical implications since they suggest that loneliness should not be conflated with the expression of schizotypy. Rather, loneliness needs to be specifically targeted for assessment and treatment in youth at risk for psychosis.

Subtalar Coalitions: Does the Morphology of the Subtalar Joint Involvement Influence Outcomes After Coalition Excision?

PubMed

Mahan, Susan T; Prete, Victoria I; Spencer, Samantha A; Kasser, James R; Bixby, Sarah D

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score). Blinded analysis of the preoperative CT scan findings determined the presence of a standard MF versus a PMST coalition. The perioperative factors and postoperative outcomes between the MF and PMST coalitions were compared. A total of 51 feet (36 patients) were included. The mean follow-up duration was 2.6 years after surgery. Of the 51 feet, 15 (29.4%) had a PMST coalition and 36 (70.6%) had an MF coalition. No difference was found in the UCLA activity score; however, the mean AOFAS scale score was higher for patients with PMST (95.7) than for those with MF (86.5; p = .018). Of the patients with a PMST, none had foot pain limiting their activities at the final clinical follow-up visit. However, in the group with an MF subtalar coalition, 10 (27.8%) had ongoing foot pain limiting activity at the final follow-up visit (p = .024). Compared with MF subtalar tarsal coalitions, patients with PMST coalitions showed significantly improved clinical outcomes after excision. Preoperative identification of the facet morphology can improve patient counseling and expectations after surgery. Copyright © 2017 American College of Foot and Ankle Surgeons.

Interscalene block (ISB) can provide pain relief after shoulder surgery, but a reliable quantification of its analgesic benefits is lacking. This meta-analysis examines the effect of single-shot ISB on analgesic outcomes during the first 48 hours after shoulder surgery. We retrieved randomized and quasirandomized controlled trials examining the analgesic benefits of ISB compared with none in shoulder surgery. Severity of postoperative pain measured on a visual analog scale (10 cm scale, 0 = no pain, 10 = worst pain) at rest at 24 hours was the designated primary outcome. Secondary outcomes included pain severity at rest and with motion at 2, 4, 6, 8, 12, 16, 32, 36, 40, and 48 hours postoperatively. Opioid consumption, postoperative nausea and vomiting, patient satisfaction with pain relief, and postanesthesia care unit and hospital discharge time were also assessed. A total of 23 randomized controlled trials, including 1090 patients, were analyzed. Patients in the ISB group had more severe postoperative pain at rest by a weighed mean difference (95% confidence interval) of 0.96 cm (0.08-1.83; P = 0.03) at 24 hours compared with no ISB, but there was no difference in pain severity beyond that point. The duration of pain relief at rest and with motion after ISB were 8 and 6 hours, respectively, with a corresponding weighed mean difference in visual analog scale pain scores (99% confidence interval) of -1.59 cm (-2.60 to -0.58) and -2.20 cm (-4.34 to -0.06), respectively, with no additional pain relief benefits beyond these points. ISB reduced postoperative opioid consumption up to 12 hours, decreased postoperative nausea and vomiting at 24 hours, and expedited postanesthesia care unit and hospital discharge. The type, dose, and volume of local anesthetic used did not affect the results. ISB can provide effective analgesia up to 6 hours with motion and 8 hours at rest after shoulder surgery, with no demonstrable benefits thereafter. Patients who receive an ISB can suffer rebound pain at 24 hours but later experience similar pain severity compared with those who do not receive an ISB. ISB can also provide an opioid-sparing effect and reduce opioid-related side effects in the first 12 and 24 hours postoperatively, respectively. These findings are useful to inform preoperative risk-benefit discussions regarding ISB for shoulder surgery.

The purpose of this study was to prospectively evaluate the effect of benzyl alcohol, a common preservative in normal saline, on postprocedural pain after intraarticular injection for direct shoulder MR arthrography. From April 2011 through January 2013, 138 patients underwent direct shoulder MR arthrography. Using the Wong-Baker Faces Pain Scale, patients were asked to report their shoulder pain level immediately before and immediately after the procedure and then were contacted by telephone 6, 24, and 48 hours after the procedure. Fourteen patients did not receive the prescribed amount of contrast agent for diagnostic reasons or did not complete follow-up. Sixty-two patients received an intraarticular solution including preservative-free normal saline (control group) and 62 patients received an intraarticular solution including normal saline with 0.9% benzyl alcohol as a contrast diluent (test group). Patients were randomized as to which intraarticular diluent they received. Fluoroscopic and MR images were reviewed for extracapsular contrast agent administration or extravasation, full-thickness rotator cuff tears, and adhesive capsulitis. The effect of preservative versus control on pain level was estimated with multiple regression, which included time after procedure as the covariate and accounted for repeated measures over patients. Pain scale scores were significantly (p = 0.0382) higher (0.79 units; 95% CI, 0.034-1.154) with benzyl alcohol preservative compared with control (saline). In both study arms, the pain scale scores decreased slightly after the procedure, increased by roughly 1 unit over baseline for the test group and 0.3 unit over baseline for the control group by 6 hours after the procedure, were 0.50 unit over baseline for the test group and 0.12 unit over baseline for the control group at 24 hours, then fell to be slightly greater than baseline at 48 hours with benzyl alcohol and slightly less than baseline without benzyl alcohol. These trends over time were highly significant (p < 0.0001). Shoulder arthrography is often associated with postprocedural discomfort that begins immediately after the procedure and resolves by 48 hours. There is significantly increased patient discomfort at 6 and 48 hours when using normal saline preserved with benzyl alcohol as a diluent compared with using normal saline without preservative as a diluent.

Muscle fatigue affecting glenohumeral and/or scapular muscles is suggested as one of the contributing factors to the development of subacromial impingement syndrome (SAIS). Nonetheless, the fatigability of shoulder girdle muscles in association with the pathomechanics of SAIS has not been reported. This study aimed to measure and compare fatigue progression within the shoulder girdle musculature of patients and healthy controls. 75 participants including 39 patients (20 females; 19 males) and 36 healthy controls (15 females; 21 males) participated in the study. Study evaluated the progression of muscle fatigue in 15 shoulder girdle muscles by means of surface and fine-wire EMG during submaximal contraction of four distinct movements (abduction, flexion, internal and external rotation). Shoulder strength, subjective pain experience (McGill Pain Questionnaire), and psychological status (Hospital Anxiety and Depression Scale) were also assessed. The results were compared between patient and control groups according to the gender. Despite marked fatigue observed in the majority of muscles particularly during flexion and abduction at 90°, overall results indicated a lower tendency of fatigue progression in the impingement group across the tests (p < 0.05 - p < 0.001). Shoulder Strength, pain experience, and psychological status were significantly different between the two groups (P < .05). Lower tendency to fatigue progression in the impingement group can be attributed to the presence of fear avoidance and pain-related muscle inhibition, which in turn lead to adaptations in motor programme to reduce muscle recruitment and activation. The significantly higher levels of pain experience and anxiety/depression in the impingement group further support this proposition. Copyright © 2017 Elsevier Ltd. All rights reserved.

Shoulder dislocation is the most common dislocation among the large joints. The aim here was to compare the effectiveness of reduction of acute anterior shoulder dislocation with or without articular anesthesia. Prospective randomized trial conducted in Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-Unifesp). From March 2008 to December 2009, 42 patients with shoulder dislocation were recruited. Reductions using traction-countertraction for acute anterior shoulder dislocation with and without lidocaine articular anesthesia were compared. As the primary outcome, pain was assessed through application of a visual analogue scale before reduction, and one and five minutes after the reduction maneuver was performed. Complications were also assessed. Forty-two patients were included: 20 in the group without analgesia (control group) and 22 in the group that received intra-articular lidocaine injection. The group that received intra-articular lidocaine had a statistically greater decrease in pain over time than shown by the control group, both in the first minute (respectively: mean 2.1 (0 to 5.0), standard deviation, SD 1.3, versus mean 4.9 (2.0 to 7.0, SD 1.5; P < 0.001) and the fifth minute (respectively: mean 1.0; 0 to 3.0; SD = 1.0 versus mean 4.0; 1.0 to 6.0; SD = 1.4; P < 0.001). There was one failure in the control group. There were no other complications in either group. Reduction of anterior shoulder dislocation using intra-articular lidocaine injection is effective, since it is safe and diminishes the pain. ISRCTN27127703.

Regional anesthesia and analgesia for shoulder surgery is most commonly performed via interscalene nerve block. We developed an ultrasound-guided technique that specifically targets the C5 nerve root proximal to the traditional interscalene block and assessed its efficacy for shoulder analgesia. Prospective case series. Vanderbilt Bone and Joint Surgery Center. Patients undergoing shoulder arthroscopy at an ambulatory surgery center. Thirty-five outpatient shoulder arthroscopy patients underwent an analgesic nerve block using a new technique where ultrasound visualization of the C5 nerve root served as the primary target at a level proximal to the traditional interscalene approach. The block was performed with 15mL of 0.5% plain ropivicaine. Post anesthesia care unit pain scores, opioid consumption, hand strength, and duration of block were recorded. Cadaver dissection after injection with methylene blue confirmed that the primary target under ultrasound visualization was the C5 nerve root. Pain scores revealed 97% patients had 0/10 pain at arrival to PACU, with 91% having a pain score of 3/10 or less at discharge from PACU. Medical Research Council (MRC) hand strength mean (SD) score was 4.17 (0.92) on a scale of 1-5. The mean (SD) duration of the block was 13.9 (3.5) hours. A new technique for ultrasound-guided blockade at the level of the C5 nerve root proximal to the level of the traditional interscalene block is efficacious for shoulder post-operative pain control.

To examine the efficiency of electrical stimulation in combination with Bobath techniques in the prevention of inferior and anterior shoulder subluxation in acute stroke patients. A prospective randomized controlled trial. Intensive care unit and inpatient clinics of neurology in a university hospital. Forty-eight patients with acute stroke, divided equally into control and study groups. Subjects in both groups were treated in accordance with the Bobath concept during the early hospitalization period. In addition to Bobath techniques, electrical stimulation was also applied to the supraspinatus muscle, mid and posterior portions of the deltoid muscle of patients in the study group. Two radiological methods were used to measure the horizontal, vertical and total asymmetry and vertical distance values of the shoulder joint. Motor functions of the arm were evaluated with the Motor Assessment Scale. The hospitalization period was 12.62 ± 2.24 days for the control group and 11.66 ± 1.88 days for the study group. Shoulder subluxation occurred in 9 (37.5%) subjects in the control group, whereas it was not observed in the study group. All shoulder joint displacement values were higher in the control group than in the study group (horizontal asymmetry P = 0.0001, vertical asymmetry P = 0.0001, total asymmetry P = 0.0001, vertical range P = 0.002). Application of electrical stimulation combined with the Bobath approach proved to be efficient in preventing inferior and anterior shoulder subluxation in the acute stages of stroke.

Local administration of opioids causes effective analgesia without adverse effects related to the central nervous system. After the beneficial demonstration of peripheral opioid receptors in joint synovia, intra-articular opioid injections were used for pain treatment. Clinical studies have reported the safety and efficacy of hyaluronate injection in the shoulder joint of patients with osteoarthritis, periarthritis, rotator cuff tears, and adhesive capsulitis. To estimate the efficacy of intra-articular hyaluronate and tramadol injection for adhesive capsulitis of the shoulder compared with that of intra-articular hyaluronate injection alone. Thirty patients with adhesive capsulitis of the shoulder were randomized to the hyaluronate group (n= 16) or the tramadol group (n= 14). Hyaluronate group members were administered five weekly intra-articular hyaluronate injections; tramadol group members were administered three weekly intra-articular hyaluronate and tramadol injections and then two weekly intra-articular injections of hyaluronate. Visual Analog Scale (VAS), passive range of motion (PROM) of the shoulder joint, and Shoulder Pain and Disability Index (SPADI) scores were assessed at baseline and weeks 1, 2, 3, 4, and 6 after the initial injection. A significant improvement was observed in VAS, PROM, and SPADI scores between time points in both groups. In comparison in both groups at weeks 1 and 2 after the initial injection the VAS scores of the tramadol group were significantly lower than those of the hyaluronate group. Intra-articular hyaluronate with tramadol showed more rapid and strong analgesic effects than intra-articular hyaluronate alone and did not induce any adverse effects.

The role of sex as an important biological determinant of vulnerability to sustaining injury and gender as a social determinate of access to resources, referral for medical care and perceived disability remains conflicted in injured workers. The purpose of this study was to examine sex and gender disparity following a compensable work-related shoulder injury. This study involved cross-sectional analyses of data of two independent samples of workers with shoulder injury. Measures of disability and pain were the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Numerical Pain Rating Scale (NPRS) for patients seen at an Early Shoulder Physician Assessment (ESPA) program and the American Shoulder and Elbow Surgeons (ASES) assessment form and Visual Analogue Scale (VAS) for the sample who underwent surgery. The files of 1000 (443 females, 557 men) consecutive patients seen at an ESPA program and 150 (44 females, and 106 men) consecutive patients who underwent rotator cuff surgery (repair or decompression) were reviewed. Significant gender disparity was observed in the referral pattern of injured workers seen at the ESPA program who were referred for surgical consultation (22 vs. 78 % for females and males respectively, p < 0.0001). The independent rotator cuff surgical group had a similar gender discrepancy (29 % vs. 71 %, p < 0.0001). The timeframe from injury to surgery was longer in women in the surgical group (p = 0.01). As well, women waited longer from the date of consent to date of surgery (p = 0.04). Women had higher incidence of repetitive injuries (p = 0.01) with men reporting higher incidence of falls (p = 0.01). Women seen at the ESPA program were more disabled than men (p = 0.02). Women in both samples had a higher rate of medication consumption than men (p = 0.01 to <0.0001). Men seen at the ESPA program had a higher prevalence of full thickness rotator cuff tears (p < 0.0001) and labral pathology (p = 0.01). However, these pathologies did not explain gender disparity in the subsample of ESPA who were referred for surgical consultation or those who had surgery. Sex and gender disparity exists in workers with shoulder injuries and is evident in the mechanism of injury, perceived disability, medication consumption, referral pattern, and wait time for surgery.

The critical shoulder angle (CSA) is the angle created between the superior and inferior bone margins of the glenoid and the most lateral border of the acromion. A few studies recently investigated the relation between CSA and functional outcomes after rotator cuff repair. However, there is a lack of research investigating the effect of CSA on postoperative tendon integrity after rotator cuff repair. To assess the effects of the CSA on postoperative tendon integrity after rotator cuff repair. Cohort study; Level of evidence, 3. All patients who underwent rotator cuff repair for full-thickness supraspinatus tears by 1 senior surgeon between January 2010 and January 2014 were included in this study. All patients had standardized anteroposterior shoulder radiographs the day before surgery. CSA and acromial index (AI) were measured. AI was derived by measuring the distance from the glenoid plane to the lateral border of the acromion and dividing it by the distance from the glenoid plane to the lateral aspect of the humeral head. Functional scores-including American Shoulder and Elbow Surgeons shoulder evaluation form, modified University of California at Los Angeles score, Constant-Murley score, and visual analog scale for pain-were used to evaluate shoulder function at a minimum follow-up of 2 years. Meanwhile, magnetic resonance imaging examinations were performed to evaluate rotator cuff integrity according to the Sugaya method and the signal/noise quotient (SNQ) of the rotator cuff tendon. A total of 90 patients were included in this study: 42 patients with a single-row repair and 48 with a double-row repair. There was a significant positive correlation between CSA or AI and tendon SNQ. On the basis of CSA, the patients were divided into 2 groups: large CSA (>38°) and control (CSA ≤38°). At final follow-up, the large CSA group and the control CSA group demonstrated no significant differences in American Shoulder and Elbow Surgeons, University of California at Los Angeles, Constant, and visual analog scale scores. Postoperative magnetic resonance imaging revealed that the large CSA group had 9 cases of retear, with a significantly higher retear rate than the control group (15% vs 0%, P = .03). Furthermore, the tendon SNQ of the large CSA group was significantly greater than that of the control group. CSA did not appear to influence postoperative functional outcomes, while those in the large CSA group had poor tendon integrity after rotator cuff repair. These findings indicate that a large CSA is associated with an increased risk of rotator cuff tendon retear after repair.

The aim of this study was to assess whether side-to-side differences in morphology and function of the upper limbs in 11-12 year-old male baseball players with throwing-related pain (n=14) were more pronounced than that of age-matched healthy untrained subjects (n=16). Baseball players 1) had played baseball≥4.5 h·wk -1 for ≥ 4 years and (2) suffered from moderate-intensity (3-6 points on 10-point questionnaire scale) throwing-related pain in the shoulder or elbow in at least 2 training sessions within the past month. The range of motion (ROM), function and structure of the elbows and shoulders were assessed using goniometry, isokinetic dynamometry and ultrasonography. While the ROM and eccentric external peak torque of internal shoulder rotation were lower, the thickness of the supraspinatus tendon, the ulnar collateral ligament and articular cartilage of the humeral head were larger in baseball players than controls. There were, however, no significant side-to-side differences in any parameter in either group. In conclusion, it is unlikely that side-to-side differences in shoulder and upper limb structure and function contributed to the throwing-related pain in young baseball players, but low shoulder eccentric external peak torque and range of internal rotation may predispose to throwing-related pain. © Georg Thieme Verlag KG Stuttgart · New York.

Moderate to severe ipsilateral shoulder pain is a common complaint following thoracic surgery. In this prospective, parallel-group study at Odense University Hospital, 76 patients (aged > 18 years) scheduled for lobectomy or pneumonectomy were randomised 1:1 using a computer-generated list to receive an ultrasound-guided supraclavicular phrenic nerve block with 10 ml ropivacaine or 10 ml saline (placebo) immediately following surgery. A nerve catheter was subsequently inserted and treatment continued for 3 days. The study drug was pharmaceutically pre-packed in sequentially numbered identical vials assuring that all participants, healthcare providers and data collectors were blinded. The primary outcome was the incidence of unilateral shoulder pain within the first 6 h after surgery. Pain was evaluated using a numeric rating scale. Nine of 38 patients in the ropivacaine group and 26 of 38 patients in the placebo group experienced shoulder pain during the first 6 h after surgery (absolute risk reduction 44% (95% CI 22-67%), relative risk reduction 65% (95% CI 41-80%); p = 0.00009). No major complications, including respiratory compromise or nerve injury, were observed. We conclude that ultrasound-guided supraclavicular phrenic nerve block is an effective technique for reducing the incidence of ipsilateral shoulder pain after thoracic surgery. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

A locomotive syndrome (LS) risk test for evaluation of physical ability is recently proposed. The objective of this study is to evaluate the utility of this test by examining physical ability, neuropathic pain, nociceptive pain, shoulder complaints, and quality of life (QOL). A prospective cohort study was conducted in 523 subjects (240 males, 283 females; mean age: 63.3 years) at a health checkup. Data collected using visual analog scales (VAS) for shoulder pain, low back pain, sciatica, and knee pain, neuropathic pain, shoulder complaint, body mass index (BMI), osteoporosis, and SF-36 were compared among three LS risk stages. Subjects in LS risk stage 1 (24%) had significantly more osteoporosis, slower gait speed, weaker muscle strength and higher VAS, with no difference in age and BMI compared to those with no LS risk (50%). Subjects in stage 2 (26%) had significantly poorer results for all items. Shoulder complaint, neuropathic pain and QOL differed significantly among all three groups and worsened with decline in mobility on the LS risk test. LS risk test is easy and useful screening tool for evaluation of mobility and for screening for pain and complaint associated with activity of daily living and QOL.

The purpose of this study was to compare virtual MR arthroscopic reconstructions with arthroscopic images in patients affected by shoulder joint instability. MR arthrography (MR-AR) of the shoulder is now a well-assessed technique, based on the injection of a contrast medium solution, which fills the articular space and finds its way between the rotator cuff (RC) and the glenohumeral ligaments. In patients with glenolabral pathology, we used an additional sequence that provided virtual arthroscopy (VA) post-processed views, which completed the MR evaluation of shoulder pathology. We enrolled 36 patients, from whom MR arthrographic sequence data (SE T1w and GRE T1 FAT SAT) were obtained using a GE 0.5 T Signa--before any surgical or arthroscopic planned treatment; the protocol included a supplemental 3D, spoiled GE T1w positioned in the coronal plane. Dedicated software loaded on a work-station was used to elaborate VAs. Two radiologists evaluated, on a semiquantitative scale, the visibility of the principal anatomic structures, and then, in consensus, the pathology emerging from the VA images. These images were reconstructed in all patients, except one. The visualization of all anatomical structures was acceptable. VA and MR arthrographic images were fairly concordant with intraoperative findings. Although in our pilot study the VA findings did not change the surgical planning, the results showed concordance with the surgical or arthroscopic images.

The purpose of this study was to determine the effect of Clinical Pilates exercises on patients with shoulder pain. Thirty-three patients, experiencing shoulder pain continuously for at least four weeks were selected as study subjects. The patients were randomly divided into two groups, namely Clinical Pilates exercise (n = 17) group and conventional exercise (n = 16) group. The patients were treated for five days a week, the total treatment being carried out for 10 days. The assessment of pain and disability amongst the patients were done at the baseline and at the end of the treatment sessions, using Visual Analogue Scale (VAS) and Shoulder Pain and Disability Index (SPADI). The clinical Pilates exercise group showed a significant improvement in all scores used for assessment (p < 0.05), while the conventional exercise group demonstrated a significant improvement only in the SPADI total score (p < 0.05). A comparison of scores for the VAS, SPADI-Pain and SPADI-Total between the two groups, revealed a significant improvement in the Clinical Pilates exercise group (p < 0.05). It was demonstrated by the study that Clinical Pilates exercise is an efficient technique for patients experiencing shoulder pain, as it helps reduce pain and disability among them.

Calcific and noncalcific tendinitis of the shoulder can be unresponsive to conventional therapies. Extracorporeal shock-wave therapy (ESWT) has been suggested as an alternative treatment. To assess the efficacy of ESWT in patients with calcific and noncalcific tendinitis. MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, Web of Science, and Google Scholar were searched up to 1 November 2013. Randomized, controlled trials (RCTs) comparing high-energy versus low-energy ESWT or placebo for treatment of calcific or noncalcific tendinitis of the shoulder. Outcome measures included pain (visual analogue scale score), functional assessment (Constant-Murley score), and resolution of calcifications. Three independent reviewers abstracted data and determined eligibility and quality by consensus. Twenty-eight RCTs met the inclusion criteria. Studies were heterogeneous. Twenty RCTs compared ESWT energy levels and placebo and consistently showed that high-energy ESWT was significantly better than placebo in decreasing pain and improving function and resorption of calcifications in calcific tendinitis. No significant difference was found between ESWT and placebo in treatment of noncalcific tendinitis. The number of RCTs was small, and the studies were heterogeneous. High-energy ESWT is effective for improving pain and shoulder function in chronic calcific shoulder tendinitis and can result in complete resolution of calcifications. This therapy may be underutilized for a condition that can be difficult to manage. None.

Presentation on the Modeling and Educational Demonstrations Laboratory Curriculum Materials Center (MEDL-CMC): A Working Model and Progress Report

Physical analog models and demonstrations can be effective educational tools for helping instructors teach abstract concepts in the Earth, planetary, and space sciences. Reducing the learning challenges for students using physical analog models and demonstrations, however, can often increase instructors' workload and budget because the cost and time needed to produce and maintain such curriculum materials is substantial. First, this presentation describes a working model for the Modeling and Educational Demonstrations Laboratory Curriculum Materials Center (MEDL-CMC) to support instructors' use of physical analog models and demonstrations in the science classroom. The working model is based on a combination of instructional resource models developed by the Association of College & Research Libraries and by the Physics Instructional Resource Association. The MEDL-CMC aims to make the curriculum materials available for all science courses and outreach programs within the institution where the MEDL-CMC resides. The sustainability and value of the MEDL-CMC comes from its ability to provide and maintain a variety of physical analog models and demonstrations in a wide range of science disciplines. Second, the presentation then reports on the development, progress, and future of the MEDL-CMC at the University of California Los Angeles (UCLA). Development of the UCLA MEDL-CMC was funded by a grant from UCLA's Office of Instructional Development and is supported by the Department of Earth, Planetary, and Space Sciences. Other UCLA science departments have recently shown interest in the UCLA MEDL-CMC services, and therefore, preparations are currently underway to increase our capacity for providing interdepartmental service. The presentation concludes with recommendations and suggestions for other institutions that wish to start their own MEDL-CMC in order to increase educational effectiveness and decrease instructor workload. We welcome an interuniversity collaboration to further develop the MEDL-CMC model.

A National Science Foundation Graduate Teaching Fellows in K- 12 Education program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/ ) partners UCLA faculty and graduate students (fellows) with urban middle and high school science teachers and their students to foster programs of science and engineering exploration that bring the environment of Los Angeles into the classroom. UCLA graduate fellows serve as scientists-in-residence at four partner schools to integrate inquiry-based science lessons, facilitate advancements in science content teaching, and ultimately, to improve their own science communication skills. As part of their fellowship, graduate students are required to develop inquiry-based lessons in their partner classroom. During the first two years of the project, the SEE-LA fellows have developed a range of inquiry-based activities, from invertebrate observations in an urban stream system, to water and home energy consumption surveys, to a school biodiversity investigation, to a school-wide alternative energy fair, to engineering the cleanup of environmental disasters, such as the recent oil spill in the Gulf of Mexico. Several of the current fellows have dissertation research in water resource related fields and are specifically integrating lessons specific to their research into their partner classrooms, including urban stream water quality, post-fire watershed behavior, beach water quality assessment and E. coli source tracking. This presentation will provide an overview of goals of the SEE-LA GK-12 program, development of inquiry-based water resource lessons and resulting engagement in the partner classrooms. University and local pre-college school partnerships provide an excellent opportunity to support the development of graduate student communication and teaching skills while also contributing significantly to the integration of science education into K-12 curriculum.

A National Science Foundation Graduate Teaching Fellows in K- 12 Education program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA) has just completed its first year (of a five-year program) and has greatly expanded UCLA’s science and engineering partnerships with LA Unified and Culver City Unified School Districts. The SEE-LA program partners UCLA faculty, graduate students (fellows), middle and high school science teachers and their students into a program of science and engineering exploration that brings the environment of Los Angeles into the classroom. UCLA graduate fellows serve as scientists-in-residence at the four partner schools to integrate inquiry-based science and engineering lessons, facilitate advancements in science content teaching, and ultimately, to improve their own science communication skills. As part of their fellowship, graduate students are required to develop three inquiry-based lessons in their partner classroom, including a lesson focused on their dissertation research, a lesson focused on the environmental/watershed theme of the project, and a lesson that involves longer-term data collection and synthesis with the grade 6-12 teachers and students. The developed long-term projects ideally involve continued observations and analysis through the five-year project and beyond. During the first year of the project, the ten SEE-LA fellows developed a range of long-term research projects, from seasonal invertebrate observations in an urban stream system, to home energy consumption surveys, to a school bioblitz (quantification of campus animals and insects). Examples of lesson development and integration in the classroom setting will be highlighted as well as tools required for sustainability of the projects. University and local pre-college school partnerships provide an excellent opportunity to support the development of graduate student communication skills while also contributing significantly to the integration of sustainable research projects into K-12 curriculum.

To demonstrate the in situ repair technique of high-degree partial-thickness articular surface lesions of the supraspinatus tendon (SS). The procedure consists of the arthroscopic surgical repair of these lesions, without the need to complete the lesion, as occurs in traditional classical technique. A small incision is made in the longitudinal direction of the intact bursal fibers and where bone fixation anchors are introduced, which makes the procedure easier. These anchors are transferred to the tendon and thus enable the repair of the lesion. 48 shoulders were operated in the period 2010-2015. The minimum follow-up was 12 months and maximum 60 months. Ages ranged from 38 years to 75 years (mean 54 years). They were indicated for the repair of high-degree symptomatic lesions and at least 30% intact superior bursal fibers of good quality. Patients were evaluated according to the UCLA criteria, the results were: 69% excellent, 17% good, 7% fair, and 7% poor. Fair results occurred in three patients with associated symptoms of polyarthralgia who remained with residual pain. Three patients developed postoperative joint stiffness (7%). The procedure under study is safe and easy to reproduce. It shows high rates of positive results (86%). The opening made in the bursal side of the SS tendon allowed the arthroscope to remain in the subacromial space, making it easier to perform surgery.

Socioeconomic variables influence various healthcare issues in different ways. The effect of socioeconomic variables on the shoulder has not been well studied. Because activity level, defined by how much a patient actually does, is an important patient outcome measure and prognostic factor for the shoulder, studying its association with occupation and income will advance our understanding of how these variables relate to shoulder disorders, treatments, and outcomes. We asked: (1) Does shoulder activity score correlate with income level, stratified by gender? (2) Do different employment groups-heavy, moderate, light, student, retired-have different shoulder activity scores, as stratified by gender? (3) Is type of sports participation (contact or overhead) associated with income level, employment type, race, or household size? A survey collected the Brophy and Marx shoulder activity score and demographic information, such as age, gender, race, income, type of employment, and household size from 1625 individuals 18 years and older with no current or previous shoulder pain or injury who are members of a research panel matched to the United States population by age, gender, household income and size, race/ethnicity, and geography. Men and women were analyzed separately. Activity level was controlled for age. Shoulder activity correlated with income level among men (R = 0.03; p < 0.001) and women (R = 0.06; p = 0.0002). For men, heavy employment had the highest Shoulder Activity Scale (SAS) level (12.1 ± 4.9), which was more than SAS levels in sedentary (9.1 ± 4.5; mean difference, 3.0; 95% CI, 2.5-3.6; p = 0.001), student (8.8 ± 5.1; mean difference, 3.3; 95% CI, 3.0-3.7; p = 0.007), retired (8.0 ± 4.6; mean difference, 4.1; 95% CI, 3.6-4.7; p = 0.0001), and not working (7.5 ± 5.3; mean difference, 4.6; 95% CI, 4.6-4.6; p < 0.001) categories; similarly, for women, heavy employment had the highest SAS level (12.0 ± 5.8). However, as there were few women working in heavy labor, the only significant difference in women was between moderate employment (8.8 ± 4.2) and sedentary employment (7.0 ± 4.1; mean difference, 1.8; 95% CI, 1.6-1.9; p = 0.0015). Participation in contact (19.9% vs 12.0%; p = 0.006) and overhead sports (25.2% vs 14.2%; p < 0.001) was greater among males with higher incomes. Shoulder activity level is related to the socioeconomic factors of income and type of employment. Heavy laborers have higher shoulder activity level, likely directly related to their work. Individuals with higher incomes also have higher shoulder activity level, probably attributable to recreation as evidenced by their greater participation in contact and overhead sports. Independent of the underlying cause, these patients probably are more likely to seek treatment for shoulder disorders and may be more challenging to treat because of their elevated activity level. Future research should focus on how elevated activity level in these populations affects their risk for shoulder disorders, and their use of and outcomes from treatment for these disorders.

Although platelet-rich plasma (PRP) has been used in rotator cuff repair, most authors have been unable to report the advantages of this method in clinical trials. The use of PRP promotes better functional and structural results in arthroscopic rotator cuff repair. Randomized controlled trial; Level of evidence, 1. This was a prospective, randomized, double-blind study with 2 groups of 27 patients each (PRP group and control group). Complete supraspinatus tears with retraction of less than 3 cm were subjected to arthroscopic single-row repair; at the end of the surgical procedure, liquid PRP prepared by apheresis was given to the patients in the PRP group with autologous thrombin. The outcomes were assessed by the University of California at Los Angeles (UCLA) and Constant scales, visual analog scale (VAS) for pain, and magnetic resonance imaging (MRI) before and 3, 6, 12, and 24 months after surgery. The significance level was 5%. The 2 groups of patients exhibited significant clinical improvement (P < .001). Between the preoperative assessment and 24-month follow-up, the mean UCLA score increased from 13.63 ± 3.639 to 32.70 ± 3.635 and from 13.93 ± 4.649 to 32.44 ± 4.318 in the control and PRP groups, respectively (P = .916). The mean Constant score increased from 47.37 ± 11.088 to 85.15 ± 9.879 in the control group and from 46.96 ± 11.937 to 84.78 ± 14.048 in the PRP group (P = .498). The mean VAS score varied from 7.00 ± 1.939 and 6.67 ± 1.617 before surgery to 1.15 ± 1.916 and 0.96 ± 2.244 at the 24-month assessment in the control and PRP groups, respectively (P = .418). The only difference was in the mean UCLA score at 12 months, with 30.04 ± 4.528 in the control group and 32.30 ± 3.506 in the PRP group (P = .046). The control group exhibited 1 case of a complete retear and 4 partial retears, and the PRP group exhibited 2 cases of partial retears (P = .42). Platelet-rich plasma prepared by apheresis and applied in the liquid state with thrombin did not promote better clinical results at 24-month follow-up. Given the numbers available for analysis, the retear rate also did not change. © 2014 The Author(s).

[Purpose] The aim of this study was to evaluate the musculoskeletal symptoms, pain and risk of postures as well as the effects of stretching exercise on the work-related symptoms and pain of bus drivers. [Subjects and Methods] Eighty-one drivers were randomly recruited from a bus corporation for this study. Information about pain levels, painful regions, and general characteristics of subjects was obtained using the symptom research form (KOSHA Code H-30-2003). The level of pain was assessed on a scale of numeric rating scale (NRS) which is divided by 10. Ergonomic posture assessment was conducted using the rapid upper limb assessment (RULA). Self-stretching exercise was performed for 4 weeks by the bus drivers who suffered from neck and shoulder pain. [Results] Musculoskeletal symptoms were present in the order of shoulder, neck, lower back and lower extremities. Compared with other jobs, the final score, and the action level of bus drivers were very high, showing 57.6% of action levels 3 and 4. A statistically significant decrease of pain was shown after the self-stretching intervention. There was also a significant decrease of musculoskeletal symptoms in the neck and shoulders after the self-stretching exercise. [Conclusion] Performing stretching for musculoskeletal symptoms had a positive influence on the symptoms and reduced pain. PMID:25540496

Background Chronic rotator cuff pathology (CRCP) is a common shoulder condition causing pain and disability. Physiotherapy is often the first line of management for CRCP yet there is little conclusive evidence to support or refute its effectiveness and no formal evaluation of its cost-effectiveness. Methods/Design This randomised, double-blind, placebo-controlled trial will involve 200 participants with CRCP recruited from medical practices, outpatient departments and the community via print and radio media. Participants will be randomly allocated to a physiotherapy or placebo group using concealed allocation stratified by treating physiotherapist. Both groups will receive 10 sessions of individual standardised treatment over 10 weeks from one of 10 project physiotherapists. For the following 12 weeks, the physiotherapy group will continue a home exercise program and the placebo group will receive no treatment. The physiotherapy program will comprise shoulder joint and spinal mobilisation, soft tissue massage, postural taping, and home exercises for scapular control, posture and rotator cuff strengthening. The placebo group will receive inactive ultrasound and gentle application of an inert gel over the shoulder region. Blinded assessment will be conducted at baseline and at 10 weeks and 22 weeks after randomisation. The primary outcome measures are self reported questionnaires including the shoulder pain and disability index (SPADI), average pain on an 11-point numeric rating scale and participant perceived global rating of change. Secondary measures include Medical Outcomes Study 36-item short form (SF-36), Assessment of Quality of Life index, numeric rating scales for shoulder pain and stiffness, participant perceived rating of change for pain, strength and stiffness, and manual muscle testing for shoulder strength using a handheld dynamometer. To evaluate cost-effectiveness, participants will record the use of all health-related treatments in a log-book returned to the assessor monthly. To test the effect of the intervention using an intention-to-treat analysis, linear regression modelling will be applied adjusting for baseline outcome values and other demographic characteristics. Participant measures of perceived change will be compared between groups by calculating the relative risks and their 95% confidence intervals at each time point using log binomial regression. Discussion Results from this trial will contribute to the evidence regarding the effectiveness of a physiotherapy program for the management of CRCP.

[Purpose] The purpose of this study was to investigate clinical effects of deep cervical flexor (DCF) muscles exercise on pain, Neck Disability Index (NDI), and neck and shoulder postures in patients with chronic neck pain. [Subjects and Methods] Twenty-eight patients with chronic neck pain were randomly assigned into either the general strengthening exercise (GSE) group or the DCF activation group as control and experimental groups, respectively. All exercises were performed three times per week over 4 weeks. NDI and numeric rating scale (NRS) score for pain were determined and radiological assessment of neck-shoulder postures (head tilt angle [HTA], neck flexion angle [NFA], and forward shoulder angle [FSA]) was performed before (baseline), 4 weeks after, and 8 weeks after exercise in order to directly compare the exercise effects between the groups. [Results] In the DCF group, the NDI, NRS score, and neck-shoulder postures (analyzed by uisng HTA, NFA, and FSA) were significantly improved. [Conclusion] DCF activation exercise was effective to alleviate pain, recover functions, and correct forward head posture in the patients with neck pain. Hence, it might be recommended in the rehabilitation of patients with chronic neck pain. PMID:26957772

Muscle fatigue is considered to be one cause of shoulder pain, and subjects with generalized joint hypermobility (GJH) are affected more by shoulder pain. The purpose of this study was to examine the effects of muscle fatigue on acromiohumeral distance (AHD) and scapular dyskinesis in women with GJH. Thirty-six asymptomatic participants were assigned to either a GJH (n = 20) or control group (n = 16) using the Beighton scale. Before and after elevation fatigue trials, AHD was measured with ultrasonography at rest and when the arm was in 90° active elevation. A scapular dyskinesis test was used to visually observe alterations in scapular movement. Our results showed that in both groups, the fatigue reduced AHD in the 90° elevation position and increased the presence of scapular dyskinesis; however, no differences were found between the two groups. Although GJH has been identified as a factor for developing musculoskeletal disorders, generalized joint hypermobility did not result in changes to scapular dyskinesis or AHD, even after an elevation fatigue task. More studies are needed to evaluate the effects of muscle fatigue in subjects with GJH and a history of shoulder instability.

The UCLA School of Medicine's Interactive Multi-media Exercises (IMMEX) Project began its outreach into pre-college education in the Los Angeles area in 1993. The project provides a model in which software and technology are effectively intertwined with teaching, learning, and assessment (of both students' and teachers' performances) in the classroom. The project has evolved into a special collaboration between the medical school and Los Angeles teachers. UCLA faculty and staff work with science teachers and administrators from elementary, middle, and high schools. The program benefits ethnically and racially diverse groups of students in schools ranging from the inner city to the suburbs. The project's primary goal is to use technology to increase students' achievement and interest in science, including medicine, and thus move more students into the medical school pipeline. Evaluations from outside project evaluators (West Ed) as well as from teachers and IMMEX staff show that the project has already had a significant effect on teachers' professional development, classroom practice, and students' achievement in the Los Angeles area.

To evaluate the clinical and magnetic resonance imaging (MRI) outcome of arthroscopic rotator cuff repair with the use of leukocyte-platelet-rich plasma (L-PRP) in patients with large or massive rotator cuff tears. A comparative cohort of patients with large or massive rotator cuff tears undergoing arthroscopic repair was studied. Two consecutive groups of patients were included: rotator cuff repairs with L-PRP injection (group 1, n = 35) and rotator cuff repairs without L-PRP injection (group 2, n = 35). A double-row cross-suture cuff repair was performed by a single surgeon with the same rehabilitation protocol. Patients were clinically evaluated with the Constant score; Simple Shoulder Test score; University of California, Los Angeles (UCLA) score; and strength measurements by use of a handheld dynamometer. Rotator cuff healing was evaluated by postoperative MRI using the Sugaya classification (type 1 to type 5). We prospectively evaluated the 2 groups at a minimum 2-year follow-up. The results did not show differences in cuff healing between the 2 groups (P = .16). The size of recurrent tears (type 4 v type 5), however, was significantly smaller in group 1 (P = .008). There was no statistically significant difference in the recurrent tear rate (types 4 and 5) between the 2 groups (P = .65). There was no significant difference between group 1 and group 2 in terms of University of California, Los Angeles score (29.1 and 30.3, respectively; P = .90); Simple Shoulder Test score (9.9 and 10.2, respectively; P = .94); Constant score (77.3 and 78.1, respectively; P = .82); and strength (7.5 and 7.0, respectively; P = .51). In our study the use of autologous L-PRP did not improve the quality of tendon healing in patients undergoing arthroscopic repair of large or massive rotator cuff tears based on postoperative MRI evaluation. The only significant advantage was that the L-PRP patients had smaller iterative tears. However, the functional outcome was similar in the 2 groups of patients. Level III, case-control study.

Bone Grafting the Glenoid Versus Use of Augmented Glenoid Baseplates with Reverse Shoulder Arthroplasty.

PubMed

Jones, Richard B; Wright, Thomas W; Roche, Christopher P

2015-12-01

Large glenoid defects are a difficult reconstructive problem for surgeons performing reverse shoulder arthroplasty (rTSA). Options to address glenoid defects include eccentric reaming, bone grafting, and augmented glenoid baseplates. Augmented glenoid baseplates may provide a simpler, cost-effective, bone-preserving option compared to other techniques. No studies report the use of augmented baseplates to correct glenoid deformity in rTSA relative to the use of glenoid bone graft. We retrospectively reviewed 80 patients that received a primary rTSA and received either a structural bone graft or an augmented glenoid baseplate to address a significant glenoid defect. There were 39 patients in the augmented baseplate cohort and 41 patients in the bone graft cohort. The augmented baseplate cohort contained 24 8° posterior augment implants and 15 10° superior augment baseplates. The bone graft cohort consisted of 36 autograft humeral heads and 5 allograft femoral heads. The average follow-up for rTSA patients with an augmented baseplate was 28.3 ± 5.7 months, and the average follow-up for rTSA patients with glenoid bone graft was 34.1 ± 15.0 months. Each patient was scored preoperatively and at latest follow-up using the SST, UCLA, ASES, Constant, and SPADI metrics. Range of motion data was obtained as well. All patients demonstrated significant improvements in pain, ROM, and functional scores following treatment with rTSA using either augmented baseplates or glenoid bone graft to correct glenoid defects. The database contained no complications for the augmented glenoid baseplate cohort, and six complications (14.6%) for the glenoid bone graft cohort (including two glenoid loosenings and graft failures). Additionally, the augmented baseplate cohort showed a lower scapular notching rate of 10% as compared to the bone graft cohort which had a notching rate of 18.5%. The results of this study suggest that either augmented glenoid baseplates or glenoid bone graft can be used to address large glenoid defects during rTSA with significant improvement in outcomes. Augmented glenoid baseplates may achieve a lower complication and scapular notching rate, but additional and longer-term clinical follow-up is required to confirm these results.

Postoperative shoulder pain remains a significant problem after laparoscopy. Pneumoperitoneum with insufflation of carbon dioxide (CO2) is thought to be the most important cause. Reduction of pneumoperitoneum pressure may, however, compromise surgical visualisation. Recent studies indicate that the use of deep neuromuscular blockade (NMB) improves surgical conditions during a low-pressure pneumoperitoneum (8 mmHg). The aim of this study was to investigate whether low-pressure pneumoperitoneum (8 mmHg) and deep NMB (posttetanic count 0 to 1) compared with standard-pressure pneumoperitoneum (12 mmHg) and moderate NMB (single bolus of rocuronium 0.3 mg kg with spontaneous recovery) would reduce the incidence of shoulder pain and improve recovery after laparoscopic hysterectomy. A randomised, controlled, double-blinded study. Private hospital in Denmark. Ninety-nine patients. Randomisation to either deep NMB and 8 mmHg pneumoperitoneum (Group 8-Deep) or moderate NMB and 12 mmHg pneumoperitoneum (Group 12-Mod). Pain was assessed on a visual analogue scale (VAS) for 14 postoperative days. The primary endpoint was the incidence of shoulder pain during 14 postoperative days. Secondary endpoints included area under curve VAS scores for shoulder, abdominal, incisional and overall pain during 4 and 14 postoperative days; opioid consumption; incidence of nausea and vomiting; antiemetic consumption; time to recovery of activities of daily living; length of hospital stay; and duration of surgery. Shoulder pain occurred in 14 of 49 patients (28.6%) in Group 8-Deep compared with 30 of 50 (60%) patients in Group 12-Mod. Absolute risk reduction was 0.31 (95% confidence interval 0.12 to 0.48; P = 0.002). There were no differences in any secondary endpoints including area under the curve for VAS scores. Deep NMB and low-pressure pneumoperitoneum (8 mmHg) reduced the incidence of shoulder pain after laparoscopic hysterectomy in comparison to moderate NMB and standard-pressure pneumoperitoneum (12 mmHg).

Irreparable posterosuperior rotator cuff tears are treated in several ways. Transfer of the latissimus dorsi is an alternative with acceptable mid-term results, but long-term results have rarely been published. The cases of 108 consecutive patients with 115 shoulders treated with latissimus dorsi transfer between 2000 and 2005 were reviewed clinically and radiographically. Ninety-three shoulders in eighty-six patients were included in the follow-up analysis. The mean duration of follow-up was 9.3 years (range, 6.6 to 11.7 years), and the mean age at the operation was fifty-six years (range, forty to seventy-two years). Outcome measures included the Constant-Murley score (Constant score), American Shoulder and Elbow Surgeons (ASES) index, and visual analog scale (VAS) for pain. The progress of cuff tear arthropathy was determined with radiographic evaluation according to the system described by Hamada et al. The mean relative Constant score improved from 44% preoperatively to 71% at the time of follow-up (p < 0.0001, effect size = 0.6), excluding the clinical failures. Similarly, the mean ASES index improved from 30 to 70 (p < 0.0001, effect size = 0.7), and the mean VAS score decreased from 7.8 to 2.4 (p < 0.0001, effect size = 0.8). A pain-free outcome was reported in only eighteen shoulders (19%). Active shoulder movement improved significantly (p < 0.05). The mean Hamada radiographic grade of cuff tear arthropathy increased from 1.7 (range, 0 to 2) preoperatively to 2.2 (range, 1 to 5) (p < 0.0001, effect size = 0.2). The rate of clinical failure of latissimus dorsi transfer was 10%, and the rate of shoulder prosthetic replacement after latissimus dorsi transfer was 4%. Pain relief and improvement of shoulder function were maintained a mean of 9.3 years after latissimus dorsi transfer for irreparable posterosuperior cuff defects. The younger the patient, the better the outcome. Copyright © 2015 by The Journal of Bone and Joint Surgery, Incorporated.

Post-laparoscopic pain syndrome is well recognized and characterized by abdominal and particularly shoulder tip pain; it occurs frequently following laparoscopic cholecystectomy. The etiology of post-laparoscopic pain can be classified into three aspects: visceral, incision, and shoulder. The origin of shoulder pain is only partly understood, but it is commonly assumed that the cause is overstretching of the diaphragmatic muscle fibers owing to a high rate of insufflations. This study aimed to compare the frequency and intensity of shoulder tip pain between low-pressure (7 mmHg) and standard-pressure (14 mmHg) in a prospective randomized clinical trial. One hundred and forty consecutive patients undergoing elective laparoscopic cholecystectomy were randomized prospectively to either high- or low-pressure pneumoperitoneum and blinded by research nurses who assessed the patients during the postoperative period. The statistical analysis included sex, mean age, weight, American Society of Anesthesiologists (ASA) grade, operative time, complication rate, duration of surgery, conversion rate, postoperative pain by using visual analogue scale, number of analgesic injections, incidence and severity of shoulder tip pain, and postoperative hospital stay. p < 0.05 was considered indicative of significance. The characteristics of the patients were similar in the two groups except for the predominance of males in the standard-pressure group (controls). The procedure was successful in 68 of 70 patients in the low-pressure group compared with in 70 patients in the standard group. Operative time, number of analgesic injections, visual analogue score, and length of postoperative days were similar in both groups. Incidence of shoulder tip pain was higher in the standard-pressure group, but not statistically significantly so (27.9% versus 44.3%) (p = 0.100). Low-pressure pneumoperitoneum tended to be better than standard-pressure pneumoperitoneum in terms of lower incidence of shoulder tip pain, but this difference did not reach statistical significance following elective laparoscopic cholecystectomy.

EVALUATION AND TREATMENT OF A PATIENT DIAGNOSED WITH ADHESIVE CAPSULITIS CLASSIFIED AS A DERANGEMENT USING THE MCKENZIE METHOD: A CASE REPORT.

The McKenzie Method of mechanical diagnosis and therapy (MDT) is supported in the literature as a valid and reliable approach to the management of spine injuries. It can also be applied to the peripheral joints, but has not been explored through research to the same extent. This method sub-classifies an injury based on tissue response to mechanical loading and repeated motion testing, with directional preferences identified in the exam used to guide treatment. The purpose of this case report is to demonstrate the assessment, intervention, and clinical outcomes of a subject classified as having a shoulder derangement syndrome using MDT methodology. The subject was a 52-year-old female with a four-week history of insidious onset left shoulder pain, referred to physical therapy with a medical diagnosis of adhesive capsulitis. She presented with pain (4-7/10 on the visual analog scale [VAS]) and decreased shoulder range of motion that limited her activities of daily living and work capabilities (Upper Extremity Functional Index (UEFI) score: 55/80). Active and passive ranges of motion (A/PROM) were limited in all planes. Repeated motion testing was performed, with an immediate reduction in pain and increased shoulder motion in all planes following repeated shoulder extension. As a result, her MDT classification was determined to be derangement syndrome. Treatment involved specific exercises, primarily repeated motions, identified as symptom alleviating during the evaluation process. The subject demonstrated significant improvements in the UEFI (66/80), VAS (0-2/10), and ROM within six visits over eight weeks. At the conclusion of treatment, A/PROM was observed to be equal to the R shoulder without pain. This subject demonstrated improved symptoms and functional abilities following evaluation and treatment using MDT methodology. While a cause-effect relationship cannot be determined with a single case, MDT methodology may be a useful approach to the examination, and potentially management, of patients with shoulder pain. This method offers a patient specific approach to treating the shoulder, particularly when the pathoanatomic structure affected is unclear. 4.

Development of an HIV Postexposure Prophylaxis (PEP) Protocol for Trainees Engaging in Academic Global Health Experiences.

Global health (GH) education programs have become increasingly common in U.S. medical schools and graduate medical education programs, with growing numbers of medical students, residents, and fellows participating in clinical experiences in settings with high HIV prevalence and limited resources. However, there are no guidelines for provision of HIV postexposure prophylaxis (PEP) to trainees engaging in these academic GH experiences. Faculty of the Global Health Education Programs (GHEP) at the David Geffen School of Medicine at UCLA and GH partner institutions recognized the need for PEP access for trainees engaged in GH experiences. In 2013-2014, key UCLA faculty collaborated in the development of the UCLA GHEP PEP Protocol, which includes provision of PEP medications to trainees prior to departure, an on-call infectious disease/HIV specialist to advise trainees who have exposures, and a system for following up with exposed trainees while on the GH rotation and after their return. Between February 2014 and September 2016, 112 medical students and 110 residents received education on the PEP protocol during their predeparture orientation. The protocol was used for 28 exposures (27 occupational, 1 nonoccupational), with PEP recommended in 3 occupational cases (all needlesticks) and the single nonoccupational case. There were no reported HIV seroconversions. The authors plan to formally evaluate the PEP protocol, conduct a qualitative assessment with trainees and both UCLA and GH partner faculty, and discuss best practices with institutions across the United States and with GH partners.

Despite the theoretic basis and interest in using platelet-rich plasma (PRP) to improve the potential for rotator cuff healing, there remains ongoing controversy regarding its clinical efficacy. The objective of this systematic review was to identify and summarize the available evidence to compare the efficacy of arthroscopic rotator cuff repair in patients with full-thickness rotator cuff tears who were concomitantly treated with PRP. We searched the Cochrane Central Register of Controlled Trials, Medline, Embase, and PubMed for eligible studies. Two reviewers selected studies for inclusion, assessed methodologic quality, and extracted data. Pooled analyses were performed using a random effects model to arrive at summary estimates of treatment effect with associated 95% confidence intervals. Five studies (2 randomized and 3 nonrandomized with comparative control groups) met the inclusion criteria, with a total of 261 patients. Methodologic quality was uniformly sound as assessed by the Detsky scale and Newcastle-Ottawa Scale. Quantitative synthesis of all 5 studies showed that there was no statistically significant difference in the overall rate of rotator cuff retear between patients treated with PRP and those treated without PRP (risk ratio, 0.77; 95% confidence interval, 0.48 to 1.23). There were also no differences in the pooled Constant score; Simple Shoulder Test score; American Shoulder and Elbow Surgeons score; University of California, Los Angeles shoulder score; or Single Assessment Numeric Evaluation score. PRP does not have an effect on overall retear rates or shoulder-specific outcomes after arthroscopic rotator cuff repair. Additional well-designed randomized trials are needed to corroborate these findings. Level III, systematic review of Level I, II, and III studies.

Injury to the infraclavicular brachial plexus is an uncommon but serious complication of shoulder dislocation. This work aims to determine the effectiveness of operative treatment in patients with this type of injury. Thirty-three patients (26 men and 7 women; mean age, 45 years and 3 months) treated operatively for brachial plexus injury resulting from shoulder dislocation between the years 2000 and 2013 were included in this retrospective case series. Motor function of affected limbs was assessed pre- and postoperatively with the use of the British Medical Research Council (BMRC) scale. Sensory function in the areas innervated by ulnar and median nerves was evaluated with the BMRC scale modified by Omer and Dellon and in the remaining areas with the Highet classification. Follow-up lasted 2-10 years (mean, 5.1 years). Good postoperative recovery of nerve function was observed in 100% of musculocutaneous, 93.3% of radial, 66.7% of median, 64% of axillary, and 50% of ulnar nerve injuries. No recovery was observed in 5.6% of median, 6.7% of radial, 10% of ulnar, and 20% of axillary nerve injuries. Injury to a single nerve was associated with worse treatment outcome than multiple nerve injury. Obtaining improvement in peripheral nerve function after injury resulting from shoulder dislocation may require operative intervention. The type of surgical procedure depends on intraoperative findings: sural nerve grafting in cases of neural elements' disruption, internal neurolysis when intraneural fibrosis is observed, and external neurolysis in the remaining cases. The outcomes of surgical treatment are good, and the risk of intra- and postoperative complications is low. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of our study was to compare the effectiveness of subacromial bupivacaine infusion and a transdermal fentanyl patch in the treatment of postoperative pain after arthroscopic shoulder surgery. Sixty patients with rotator cuff disease scheduled for elective arthroscopic shoulder surgery were enrolled in the study. For the treatment of postoperative pain, 30 patients constituted group F and received a 12.0-μg/h fentanyl patch for 72 hours and saline solution infusion in a subacromial manner at the rate of 4 mL/h. The remaining 30 patients constituted group B and received a placebo patch and an infusion of 2.5-mg/mL bupivacaine in a subacromial manner for 72 hours. The primary outcome measure was the postoperative numerical rating scale pain score. The consumption of opioids, ibuprofen, and acetaminophen was also recorded. The Constant scores and general recovery were followed up until the 90th postoperative day. There was no statistically significant difference in the numerical rating scale scores (P = .60) between the groups. No differences in the use of rescue analgesic were observed except that the patients receiving bupivacaine used more ibuprofen (median, 1,200 mg v 600 mg) during the day of surgery (P = .042). No difference was found in general recovery between the groups. A fentanyl patch delivering 12-μg/h fentanyl offers an easy and safe treatment option as a part of multimodal analgesia with few adverse effects in the treatment of postoperative pain in a carefully selected patient group after arthroscopic shoulder surgery.

Subacromial pain syndrome (SAPS) accounts for around 50 % of all cases of shoulder pain. The most commonly used treatments are glucocorticosteroid (steroid) injections and exercise therapy; however, despite treatment SAPS patients often experience relapse of their symptoms. Therefore the clinical effect of combining steroid and exercise therapy is highly relevant to clarify. The aim of this randomized controlled trial was to investigate if exercise therapy added to steroid injection in patients with SAPS will improve the effect of the injection therapy on shoulder pain. In this two-arm randomized trial running over 26 weeks, patients with unilateral shoulder pain (> 4 weeks) and thickened subacromial bursa (> 2 mm on US) were included. At baseline all participants received two steroid injections into the painful shoulder with an interval of one week. Subsequently they were randomized (1:1) to either 10 weeks exercise of the involved shoulder (intervention group) or exercise of the uninvolved shoulder (control group). The patients were re-examined after the exercise program (at week 13) and again at week 26. The primary outcome assessed after 26 weeks was change in shoulder pain analyzed using the intention-to-treat principle (non-responder imputation). Ninety-nine SAPS patients (58 female) participated (49 intervention/50 control). At both follow up visits (week 13 and 26) no statistically significant between-group differences in pain changes on a visual analog scale (mm) were seen (13 weeks: pain at rest 1.7 (95 % CI -3.6 to 7.0; P = 0.53); pain in activity 2.2 (95 % CI -6.5 to 10.9; P = 0.61), 26 weeks: rest 5.6 (95 % CI -0.9 to 12.1; P = 0.09); activity 2.2 (95 % CI -6.8 to 11.2; P = 0.62). The reduction in pain was most evident in the control group at all four pain measurements. The only difference between groups was seen by US examination at week 13, where fewer participants with impingement were observed in the intervention group compared with the controls (9 vs. 19 participants; P = 0.03). Exercise therapy in the painful shoulder in SAPS patients did not improve the effectiveness of steroid injections for shoulder pain in patients with unilateral SAPS and enlarged subacromial bursa on US examination.

The Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow score is a reliable and sensitive tool to measure the performance of overhead athletes. The purpose of this study was to carry out a cross-cultural adaptation and validation of the KJOC questionnaire in Italian and to assess its reliability, validity, and responsiveness. Ninety professional athletes with a painful shoulder were included in this study and were assigned to the "injury group" (n = 32) or the "overuse group" (n = 58); 65 were managed conservatively and 25 were treated by arthroscopic surgery. To assess the reliability of the KJOC score, patients were asked to fill in the questionnaire at baseline and after 2 weeks. To test the construct validity, KJOC scores were compared to those obtained with the Italian version of the Disabilities of the Arm, Shoulder, and Hand (DASH) scale, and with the DASH sports/performing arts module. To test KJOC score responsiveness, the follow-up KJOC scores of the participants treated conservatively were compared to those of the patients treated by arthroscopic surgery. Statistical analysis demonstrated that the KJOC questionnaire is reliable in terms of the single items and the overall score (ICC 0.95-0.99); that it has high construct validity (r s  = -0.697; p < 0.01); and that it is responsive to clinical differences in shoulder function (p < 0.0001). The Italian version of the KJOC Shoulder and Elbow score performed in a similar way to the English version and demonstrated good validity, reliability, and responsiveness after conservative and surgical treatment.

Effective postoperative pain management after shoulder arthroscopy is a critical component to recovery, rehabilitation, and patient satisfaction. This systematic review provides a comprehensive overview of level 1 and level 2 evidence regarding postoperative pain management for outpatient arthroscopic shoulder surgery. Systematic review. We performed a systematic review of the various modalities reported in the literature for postoperative pain control after outpatient shoulder arthroscopy and analyzed their outcomes. Analgesic regimens reviewed include regional nerve blocks/infusions, subacromial/intra-articular injections or infusions, cryotherapy, and oral medications. Only randomized control trials with level 1 or level 2 evidence that compared 2 or more pain management modalities or placebo were included. We excluded studies without objective measures to quantify postoperative pain within the first postoperative month, subjective pain scale measurements, or narcotic consumption as outcome measures. A combined total of 40 randomized control trials met our inclusion criteria. Of the 40 included studies, 15 examined nerve blocks, 4 studied oral medication regimens, 12 studied subacromial infusion, 8 compared multiple modalities, and 1 evaluated cryotherapy. Interscalene nerve blocks (ISBs) were found to be the most effective method to control postoperative pain after shoulder arthroscopy. Increasing concentrations, continuous infusions, and patient-controlled methods can be effective for more aggressively controlling pain. Dexamethasone, clonidine, intrabursal oxycodone, and magnesium have all been shown to successfully improve the duration and adequacy of ISBs when used as adjuvants. Oral pregabalin and etoricoxib administered preoperatively have evidence supporting decreased postoperative pain and increased patient satisfaction. On the basis of the evidence in this review, we recommend the use of ISBs as the most effective analgesic for outpatient arthroscopic shoulder surgery.

This study evaluated clinical outcomes of osteochondral allograft (OCA) transplantation for humeral head osteochondral defects. We hypothesized that patients with isolated humeral head disease would achieve favorable results and that patients with bipolar disease would experience inferior outcomes. We identified patients who underwent humeral head OCA transplantation. Subjective questionnaire data were obtained preoperatively and at a minimum of 2 years postoperatively. Radiographs were evaluated for graft incorporation. Failure was defined by conversion to shoulder arthroplasty, American Shoulder and Elbow Surgeons score <50, or dissatisfaction with the surgical result. Twenty patients (65% male) met inclusion criteria. Patients were an average age of 24.8 ± 8.1 years. Eleven patients underwent concomitant glenoid surgery (microfracture or meniscal allograft resurfacing). Follow-up was available for 18 patients (90%) at mean of 67 months. All grafts incorporated except 2. Four patients underwent shoulder arthroplasty at mean of 25 months postoperatively (all after pain pump chondrolysis). Eleven of the 20 patients were satisfied (all dissatisfied patients underwent glenoid surgery). Significant improvements (P < .001) were seen for the visual analog scale (from 6.1 to 1.5), Simple Shoulder Test (from 32 to 73), American Shoulder and Elbow Surgeons score (from 39 to 76), and the physical component of the 12-Item Short Form Survey (from 38 to 48). Pain pump patients who did not progress to arthroplasty experienced inferior satisfaction (40% vs. 87.5%, P = .04) and a trend toward inferior outcomes compared with the rest of the cohort. OCA transplantation is a viable option for young patients with isolated humeral chondral injury. Patients with bipolar disease or a history of intra-articular pain pump have increased failure and decreased subjective outcomes.

Neck and shoulder pain, back pain and low back pain are common symptoms in Japanese subjects, and it is important to elucidate the pathology and associated factors of these pains due to their frequency and impact on the quality of life (QOL) and activities of daily living (ADL). The purpose of the present study was to investigate whether body composition is associated with these pains. We collected the data of 273 Japanese subjects regarding the presence and the visual analogue scale (VAS) of neck and shoulder pain, back pain, low back pain and body composition parameters calculated using bioelectrical impedance analysis (BIA) technology. Furthermore, we investigated the association between these pains and the body composition using statistical methods. According to a multivariate analysis adjusted for age and gender, lower total body water ratio was significantly associated with the presence of neck and shoulder pain at present (P < 0.05); additionally, total body muscle mass (standardized β = -0.26, 95 % CI, -0.17 - -0.008, P < 0.05), total body water (standardized β = -0.27, 95 % CI, -0.23 - -0.04, P < 0.01), appendicular muscle mass (standardized β = -0.29, 95 % CI, -0.36 - -0.04, P < 0.05), and the appendicular muscle mass index (AMI) (standardized β = -0.24, 95 % CI, -1.18 - -0.20, P <0.01) were negatively correlated with the VAS of neck and shoulder pain, whereas no body composition parameters were significantly associated with back pain, low back pain at present and any type of chronic pain. The present study demonstrated that some body composition parameters regarding body water and body muscle were associated or correlated with the presence or intensity of neck and shoulder pain.

Chronic pain is influenced by biological, psychological, social, and cultural factors. The current study investigated potential roles for combinations of genetic and psychological factors in the development and/or maintenance of chronic musculoskeletal pain. An exercise-induced shoulder injury model was used and a priori selected genetic (ADRB2, COMT, OPRM1, AVPR1A, GCH1, and KCNS1) and psychological (anxiety, depressive symptoms, pain catastrophizing, fear of pain, and kinesiophobia) factors were included as predictors. Pain phenotypes were shoulder pain intensity (5-day average and peak reported on numerical rating scale), upper-extremity disability (5-day average and peak reported on the QuickDASH), and shoulder pain duration (in days). After controlling for age, sex, and race the genetic and psychological predictors were entered as main effects and interaction terms in separate regression models for the different pain phenotypes. Results from the recruited cohort (n = 190) indicated strong statistical evidence for interactions between the COMT diplotype and 1) pain catastrophizing for 5-day average upper-extremity disability and 2) depressive symptoms for pain duration. There was moderate statistical evidence for interactions for other shoulder pain phenotypes between additional genes (ADRB2, AVPR1A, and KCNS1) and depressive symptoms, pain catastrophizing, or kinesiophobia. These findings confirm the importance of the combined predictive ability of COMT with psychological distress, and reveal other novel combinations of genetic and psychological factors that may merit additional investigation in other pain cohorts.

Information on referred pain can be helpful for diagnosing diseases of the visceral organs. Here, the authors report a patient with cervical spinal cord injury (SCI) who had referred pain at the right side from the neck to shoulder, as a presentation of pulmonary embolism (PE). A 55-year-old man with complete tetraplegia, due to cervical SCI after C5 and C6 vertebral body fracture, complained of right neck-to-shoulder pain (numerical scale rating: 6). Despite pain medication (meloxicam 15 mg, gabapentin 400 mg, and propacetamol HCl 1 g), the pain was not reduced. Along with right neck-to-shoulder pain, he presented mild fever (37.8°C) and mildly elevated respiratory rate (20 breaths/min). D-dimer level was also mildly elevated to 6.09 mg/mL (normal value: < 0.5 mg/mL). Computed tomography pulmonary angiography revealed PE in the right lower lobe pulmonary artery. For managing PE, rivaroxaban was administered for three days. After the administration of rivaroxaban, the patient's pain completely disappeared. This study shows that pain at the neck-to-shoulder area can occur following unexpected causes such as PE. Not limited to PE, the evaluation of diseases in the thoracic or abdominal organs is recommended if patients with cervical SCI present refractory pain in the dermatomes innervated by high cervical nerve roots.

Shoulder pain can be difficult to treat due to its complex anatomic structure, and different treatment methods can be used. We aimed to examine the efficacy of photobiomodulation therapy (PBMT) and suprascapular nerve (SSN)-pulsed radiofrequency (RF) therapy. In this prospective, randomized, controlled, single-blind study, 59 patients with chronic shoulder pain due to impingement syndrome received PBMT (group H) or SSN-pulsed RF therapy (group P) in addition to exercise therapy for 14 sessions over 2 weeks. Records were taken using visual analog scale (VAS), Shoulder Pain and Disability Index (SPADI), and Nottingham Health Profile (NHP) scoring systems for pretreatment (PRT), posttreatment (PST), and PST follow-up at months 1, 3, and 6. There was no statistically significant difference in initial VAS score, SPADI, and NHP values between group H and group P (p > 0.05). Compared to the values of PRT, PST, and PST at months 1, 3, and 6, VAS, SPADI, and NHP values were statistically significantly lower in both groups (p < 0.001). There was no statistically significant difference at all measurement times in VAS, SPADI, and NHP between the two groups. We established that PBMT and SSN-pulsed RF therapy are effective methods, in addition to exercise therapy, in patients with chronic shoulder pain. PBMT seems to be advantageous compared to SSN-pulsed RF therapy, as it is a noninvasive method.

This study was to determine face and construct validity of a new virtual reality-based shoulder arthroscopy simulator which uses passive haptic feedback. Fifty-one participants including 25 novices (<20 shoulder arthroscopies) and 26 experts (>100 shoulder arthroscopies) completed two tests: for assessment of face validity, a questionnaire was filled out concerning quality of simulated reality and training potential using a 7-point Likert scale (range 1-7). Construct validity was tested by comparing simulator metrics (operation time in seconds, camera and grasper pathway in centimetre and grasper openings) between novices and experts test results. Overall simulated reality was rated high with a median value of 5.5 (range 2.8-7) points. Training capacity scored a median value of 5.8 (range 3-7) points. Experts were significantly faster in the diagnostic test with a median of 91 (range 37-208) s than novices with 1177 (range 81-383) s (p < 0.0001) and in the therapeutic test 102 (range 58-283) s versus 229 (range 114-399) s (p < 0.0001). Similar results were seen in the other metric values except in the camera pathway in the therapeutic test. The tested simulator achieved high scores in terms of realism and training capability. It reliably discriminated between novices and experts. Further improvements of the simulator, especially in the field of therapeutic arthroscopy, might improve its value as training and assessment tool for shoulder arthroscopy skills. II.

The aims of this study were to test the associations of the Internet addiction symptoms with impulsiveness, loneliness, novelty seeking and behavioral inhibition systems among adults with attention-deficit/hyperactivity disorder (ADHD) and adults with non-ADHD. A total of 146 adults aged between 19 and 33 years involved in this study. Participants were assessed with the Chinese version of the adult ADHD Self-report scale (ASRS), the Revised Chen Internet Addiction Scale (CIAS-R), the Barratt Impulsiveness Scale 11 (BIS-11), the Tridimensional Personality Questionnaire (TPQ), the UCLA loneliness scale, and the Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS Scale). The results of hierarchical regression analysis indicated that impulsiveness, loneliness, and behavioral inhibition system were significant predictors of Internet addition among adults with ADHD. Higher loneliness was significantly associated with more severe Internet addition symptoms among the non-ADHD group. Adults with high impulsiveness, loneliness, and BIS should be treated with caution for preventing Internet addiction. In addition, adults with and without ADHD should be provided with different preventative strategies. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Periacetabular osteotomy (PAO) is an effective treatment for symptomatic acetabular dysplasia. However, whether postoperative participation in sports leads to progression of the Kellgren-Lawrence (KL) grade of osteoarthritis (OA) in these patients is unclear. To investigate (1) participation in sports before and after PAO and (2) whether postoperative participation in sports leads to progression of the KL grade. Case-control study; Level of evidence, 3. The authors retrospectively reviewed data on 161 patients (183 hips) who underwent PAO for symptomatic acetabular dysplasia with preoperative KL grade 1 or 2 between 1998 and 2011. The mean age at the time of surgery was 42.0 ± 10.9 years (range, 12-64 years), and the mean follow-up duration was 100 months (range, 13-180 months). Data included participation in sports, the University of California, Los Angeles (UCLA) activity scale score, age at the time of surgery, body mass index, follow-up duration, history of treatment for developmental hip dislocations, Merle d'Aubigné-Postel score, Oxford Hip Score, center-edge angle, and KL grade. Univariate and multivariate analyses were applied to determine which factors were associated with progression to KL grade 3 or 4 after PAO. The number of patients who participated in sports significantly increased from 50 (31.1%) preoperatively to 89 (55.3%) postoperatively. The mean UCLA score significantly increased from 4.7 ± 2.1 preoperatively to 5.5 ± 2.0 postoperatively. The KL grade progressed to grade 3 or 4 in 16 hips, including 4 hips that underwent conversion to total hip arthroplasty. No significant differences were found in postoperative participation in sports (89 hips [53.3%] vs 11 hips [68.8%], respectively; P = .24) and the UCLA score (5.6 ± 2.0 vs 5.1 ± 2.0, respectively; P = .30) between hips with KL grade 1 or 2 and KL grade 3 or 4. A multivariate analysis revealed that no factors, including postoperative participation in sports, were significantly associated with progression to KL grade 3 or 4. Postoperative participation in sports after PAO did not significantly and negatively influence progression of the KL grade at midterm follow-up.

The biofidelity of pediatric anthropomorphic test devices (ATDs) continues to be evaluated with scaled-down adult data, a methodology that requires inaccurate assumptions about the likeness of biomechanical properties of children and adults. Recently, evaluation of pediatric ATDs by comparison of pediatric volunteer (PV) data has emerged as a valuable and practical alternative to the use of scaled adult data. This study utilized existing PV data to evaluate a 3-year-old side impact ATD, the Q3s. Though ATDs have been compared to volunteer responses in frontal impacts, this study is the first to extend ATD-PV comparison methods to the Q3s ATD and among the first to extend these methods to side impacts. Previously conducted experiments were replicated in order to make a direct comparison between the Q3s and PVs. PV data were used from 4- to 7-year-olds (shoulder tests, n=14) and 6- to 8-year-olds (sled tests, n=7). Force-deflection data were captured during quasistatic shoulder tests through manual displacement of the shoulder joint. Resulting shoulder stiffness was compared between the Q3s and PVs. Low-speed far-side sled tests were conducted with the Q3s at lateral (90°) and oblique (60°) impacts. Primary outcomes of interest included (1) lateral displacement of the torso, (2) torso rollout angle, and (3) kinematic trajectories of the head and neck. The Q3s exhibited shoulder stiffness values at least 32 N/mm greater than the PVs for all conditions (PV muscle tensed and relaxed, deflection calculated for full- and half-thoracic). In lateral sled tests, the Q3s demonstrated increased coronal torso rollout (Q3s: 49.2°; PVs: 35.7°±12.4°) and lateral (ΔY) movement of the top of the head (Q3s: -389 mm; PVs: -320±23 mm) compared to PVs. In oblique trials, the Q3s achieved significantly decreased lateral torso displacement (Q3s: 153.3 mm; PVs: 193.6±25.6 mm) and top of the head forward (ΔX) motion (Q3s: 68 mm; PVs: 133 ± 20 mm) compared to PVs. In all tests, greater downward (ΔZ) excursions of C4 and T1 were observed in the Q3s relative to PVs. Increased Q3s shoulder stiffness could affect head-neck kinematics as well as thorax responses because unrealistic force can be transmitted to the spine from the shoulder. Q3s and PV trajectories were of similar shape, although Q3s head kinematics displayed rigid body motion followed by independent lateral bending of the head, suggesting cervical and thoracic spine rigidity compared to PVs.

Participatory ergonomic intervention versus strength training on chronic pain and work disability in slaughterhouse workers: study protocol for a single-blind, randomized controlled trial

PubMed Central

2013-01-01

Background The prevalence of musculoskeletal pain in the shoulder, arm and hand is high among slaughterhouse workers, allegedly due to the highly repetitive and forceful exposure of these body regions during work. Work disability is a common consequence of these pains. Lowering the physical exposure through ergonomics intervention is the traditional strategy to reduce the workload. An alternative strategy could be to increase physical capacity of the worker through strength training. This study investigates the effect of two contrasting interventions, participatory ergonomics versus strength training on pain and work disability in slaughterhouse workers with chronic pain. Methods/design 66 slaughterhouse workers were allocated to 10 weeks of (1) strength training of the shoulder, arm and hand muscles for 3 x 10 minutes per week, or (2) participatory ergonomics involving counseling on workstation adjustment and optimal use of work tools (~usual care control group). Inclusion criteria were (1) working at a slaughterhouse for at least 30 hours per week, (2) pain intensity in the shoulder, elbow/forearm, or hand/wrist of at least 3 on a 0–10 VAS scale during the last three months, (3) pain lasting for more than 3 months, (4) frequent pain (at least 3 days per week) (5) at least moderate work disability, (6) no strength training during the last year, (7) no ergonomics instruction during the last year. Perceived pain intensity (VAS scale 0–10) of the shoulder, elbow/forearm and hand/wrist (primary outcome) and Disability of the Arm, Shoulder and Hand (Work module, DASH questionnaire) were measured at baseline and 10-week follow-up. Further, total muscle tenderness score and muscle function were assessed during clinical examination at baseline and follow-up. Discussion This RCT study will provide experimental evidence of the effectiveness of contrasting work-site interventions aiming at reducing chronic pain and work disability among employees engaged in repetitive and forceful work.

The Advanced Throwers Ten Exercise Program incorporates sustained isometric contractions in conjunction with dynamic shoulder movements. It has been suggested that incorporating isometric holds may facilitate greater increases in muscular strength and endurance. However, no objective evidence currently exists to support this claim. The purpose of this research was to compare the effects of a sustained muscle contraction resistive training program (Advanced Throwers Ten Program) to a more traditional exercise training protocol to determine if increases in shoulder muscular strength and endurance occur in an otherwise healthy population. It was hypothesized that utilizing a sustained isometric hold during a shoulder scaption exercise from the Advanced Throwers Ten would produce greater increases in shoulder strength and endurance as compared to a traditional training program incorporating a isotonic scapular plane abduction (scaption) exercise. Randomized Clinical Trial. Fifty healthy participants were enrolled in this study, of which 25 were randomized into the traditional training group (age: 26 ± 8, height:172 ± 10 cm, weight: 73 ± 13 kg, Marx Activity Scale: 11 ± 4) and 25 were randomized to the Advanced Throwers Ten group (age: 28 ± 9, height: 169 ± 23 cm, weight: 74 ± 16 kg, Marx Activity Scale: 11 ± 5). No pre-intervention differences existed between the groups (P>0.05). Arm endurance and strength data were collected pre and post intervention using a portable load cell (BTE Evaluator, Hanover, MD). Both within and between group analyses were done in order to investigate average torque (strength) and angular impulse (endurance) changes. The traditional and Advanced Throwers Ten groups both significantly improved torque and angular impulse on both the dominant and non-dominant arms by 10-14%. There were no differences in strength or endurance following the interventions between the two training groups (p>0.75). Both training approaches increased strength and endurance as the muscle loads were consistent between protocols indicating that either approach will have positive effects. Level 2.

The Great East Japan Earthquake and devastating Tsunami hit hard everything on the northeastern coast of Japan. This study aimed to determine socio-psychological factors for "subjective shoulder pain" of the survivors at 2 years evaluated by a self-report questionnaire. Between November 2012 to February 2013, survivors replied to the self-report questionnaire, and 2275 people consented to join this study. Living status was divided into 5 categories (1. same house as before the earthquake (reference group), 2. temporary small house, 3. apartment, 4. house of relatives or acquaintance, 5. new house) and economic hardship was divided into 4 categories (1. normal (reference group), 2. a little bit hard, 3. hard, 4. very hard). Gender, age, body mass index, living areas, smoking and drinking habits, complications of diabetes mellitus and cerebral stroke, working status, and walking time were considered as the confounding factors. Kessler Psychological Distress Scale of ≥10/24 and Athens Insomnia Scale of ≥6/24 points were defined as a presence of psychological distress and sleep disturbance, respectively. We used multiple logistic regression analysis to examine the association of shoulder pain with living environment, economic hardship, psychological distress, and sleep disturbance at 2 years after the earthquake. There were significant differences in the risk of having shoulder pain in those with "apartment" (OR = 1.74, 95% CI = 1.03-2.96), "house of relatives or acquaintance" (OR = 2.98, 95% CI = 1.42-6.25), economic hardship of "hard" (OR = 1.71, 95% CI = 1.08-2.7) and "very hard" (OR = 2.51, 95% CI = 1.47-4.29), and sleep disturbance (OR = 2.96, 95% CI = 2.05-4.27). Living status of "apartment" and "house of relatives or acquaintance", economic hardship of "hard" and "very hard", and "sleep disturbance" were significantly associated with shoulder pain.

The transfer of latissimus dorsi and teres major tendons to rotator cuff have been developed to rebalance the muscular dysfunction and improve shoulder range of motion in children with obstetrical brachial plexus palsy (OBPP). No previous study reported the ideal postoperative physical therapy program for these cases. The aim of the present study was to design appropriate postoperative physical therapy (PT) program after latissimus dorsi and teres major tendons transfer to rotator cuff in OBPP to improve upper limb function. Time series design. The patients were recruited from outpatient clinic of Kasr EL Aini Hospital, Cairo, Egypt. Forty seven OBPP infants (4.64±1.21 years with a range of 2.5 to 7 years, 21male and26 female) were allocated to one group. All patients had functional limitation in the involved arm due to muscle paralysis and contracture. Twenty-five patients had C5-C6 nerve root lesions while 22 had C5-C6-C7 nerve root lesions. The children underwent the surgical procedures of the transfer of latissimus dorsi and teres major tendons to rotator cuff. After the surgery the children participated in a designed physical therapy program for 6 months. Active shoulder abduction, flexion and external rotation range of motion (ROM) were assessed by electrogoniometer, and functional assessments were measured using the modified Mallet scale. All measurements were taken preoperative, 6 weeks, 3 months, and 6 months postoperatively after the application of the designed PT program. Repeated measure analysis of variance (ANOVA) followed by Bonferroni post-hoc test were used to show the improvement in all measured variables. Analysis revealed that shoulder abduction, flexion and external rotation ROM and shoulder function measured by modified Mallet scale were significantly improved (P<0.0001) after the designed postoperative PT program. It can be concluded that the combination treatment of surgical procedure and the postoperative physical therapy program seem to be effective in improving shoulder and arm functions in children with OBPP. This study describes a detailed physical therapy program after latissimus dorsi and teres major tendons transfer to rotator cuff in OBPP.

We previously showed that inactivating the anterior interpositus nucleus in cats disrupts prehension; paw paths, normally straight and accurate, become curved, hypometric, and more variable. In the present study, we determined the joint kinematic and dynamic origins of this impairment. Animals were restrained in a hammock and trained to reach and grasp a cube of meat from a narrow food well at varied heights; movements were monitored using the MacReflex analysis system. The anterior interpositus nucleus was inactivated by microinjection of the GABA agonist muscimol (0.25-0.5 microgram in 0.5 microliter saline). For each joint, we computed the torque due to gravity, inertial resistance (termed self torque), interjoint interactions (termed interaction torque), and the combined effects of active muscle contraction and passive soft tissue stretch (termed generalized muscle torque). Inactivation produced significant reductions in the amplitude, velocity, and acceleration of elbow flexion. However, these movements continued to scale normally with target height. Shoulder extension was reduced by inactivation but wrist angular displacement and velocity were not. Inactivation also produced changes in the temporal coordination between elbow, shoulder, and wrist kinematics. Dynamic analysis showed that elbow flexion both before and during inactivation was produced by the combined action of muscle and interaction torque, but that the timing depended on muscle torque. Elbow interaction and muscle torques were scaled to target height both before and during inactivation. Inactivation produced significant reductions in elbow flexor interaction and muscle torques. The duration of elbow flexor muscle torque was prolonged to compensate for the reduction in flexor interaction torque. Shoulder extension was produced by extensor interaction and muscle torques both before and during inactivation. Inactivation produced a reduction in shoulder extension, primarily by reduced interaction torque, but without compensation. Wrist plantarflexion, which occurred during elbow flexion, was driven by plantarflexor interaction and gravitational torques both before and during inactivation. Muscle torque acted in the opposite direction with a phase lead to restrain the plantarflexor interaction torque. During inactivation, there was a reduction in plantarflexor interaction torque and a loss of the phase lead of the muscle torque. Our findings implicate the C1/C3 anterior interpositus zone of the cerebellum in the anticipatory control of intersegmental dynamics during reaching, which zone is required for coordinating the motions of the shoulder and wrist with those of the elbow. In contrast, this cerebellar zone does not play a role in scaling the movement to match a target.

Multiple studies have shown that quality of care for dementia in primary care is poor, with physician adherence to dementia quality indicators (QIs) ranging from 18% to 42%. In response, the University of California at Los Angeles (UCLA) Health System created the UCLA Alzheimer's and Dementia Care (ADC) Program, a quality improvement program that uses a comanagement model with nurse practitioner dementia care managers (DCM) working with primary care physicians and community-based organizations to provide comprehensive dementia care. The objective was to measure the quality of dementia care that nurse practitioner DCMs provide using the Assessing Care of Vulnerable Elders (ACOVE-3) and Physician Consortium for Performance Improvement QIs. Participants included 797 community-dwelling adults with dementia referred to the UCLA ADC program over a 2-year period. UCLA is an urban academic medical center with primarily fee-for-service reimbursement. The percentage of recommended care received for 17 dementia QIs was measured. The primary outcome was aggregate quality of care for the UCLA ADC cohort, calculated as the total number of recommended care processes received divided by the total number of eligible quality indicators. Secondary outcomes included aggregate quality of care in three domains of dementia care: assessment and screening (7 QIs), treatment (6 QIs), and counseling (4 QIs). QIs were abstracted from DCM notes over a 3-month period from date of initial assessment. Individuals were eligible for 9,895 QIs, of which 92% were passed. Overall pass rates of DCMs were similar (90-96%). All counseling and assessment QIs had pass rates greater than 80%, with most exceeding 90%. Wider variation in adherence was found among QIs addressing treatments for dementia, which patient-specific criteria triggered, ranging from 27% for discontinuation of medications associated with mental status changes to 86% for discussion about acetylcholinesterase inhibitors. Comprehensive dementia care comanagement with a nurse practitioner can result in high quality of care for dementia, especially for assessment, screening, and counseling. The effect on treatment QIs is more variable but higher than previous reports of physician-provided dementia care. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

UCLA's Institute for Planets and Exoplanets: Structuring an Education and Public Outreach Program from the Ground Up

Geoscience education and public outreach efforts (EPO), both formal and informal, are critical to increasing science literacy amongst members of the public and securing the next generation of geoscientists. At UCLA, the Institute for Planets and Exoplanets (iPLEX) has developed a multifaceted program to administer meaningful and original hands-on education and outreach to the public, teachers/professors, and students. To build the program, we first developed a virtual "home base" using Wordpress. With the needs of our community in mind, we structured the website to serve three categories of individuals: the public, teachers/professors, and volunteers. To serve the public, we have developed a series of informal education events (e.g., Exploring Your Universe) that bring thousands of science enthusiasts to campus. For those unable to participate in hands-on demonstrations or for those who would like to see them again, informational videos were developed and made available on our online Physical Demonstrations Digital Library (PDDL). The PDDL contains a second set of videos that are tutorial in nature and specifically designed with teachers, TAs and professors in mind. In addition, we have produced a publicly available annual newsletter written at the level of the informed public that details exciting and current planetary research at UCLA. Another facet of the program, designed with teachers in mind is our application-based private outreach event system in which teachers may choose to have volunteers come to their school with interactive demos or to come to UCLA to speak with scientists and tour laboratories. The final branch of the iPLEX EPO and education program caters to volunteers and includes an online "hub" where volunteers can register for events, download demonstration information packets, and discuss tips with other volunteers. We have recently developed a "Science Education, Outreach, and Communication" course to be integrated into UCLA's undergraduate geology curriculum that will serve twofold to train new volunteers and educate young scientists on how to communicate their field to the public. Feedback from participants indicates an overall increase in geoscience EPO participation and satisfaction from the public, teachers, and volunteers alike since iPLEX's program was emplaced.

[Purpose] This study compared the effects on neck-shoulder pain and mobility of strengthening exercises for the neck flexors and scapular retractors performed on a Swiss ball and a mat. [Subjects] Twenty student volunteers were the subjects. [Methods] The students were randomly assigned to two groups: Mat group (n=10), and Swiss ball group (n=10). At pre-test, post-test, and 1-week follow-up pain was assessed using the visual analogue scale (VAS), the pain pressure threshold (PPT) of the shoulder was measured with an algometer, and neck mobility was measured with a Zebris. [Results] The data analysis revealed that there was a significant decrease in pain and significant increase in neck flexion in both groups, and the Swiss ball group showed better results. [Conclusion] Strengthening the neck flexors and scapular retractors for stabilization of the neck using exercises on a Swiss ball was more effective at reducing the pain and stabilizing the neck than mat exercises.

Although somatic symptoms are common complaints of patients with major depressive disorder (MDD), their associations with suicide are still unclear. A total of 811 MDD outpatients of aged between 18 to 64 years were enrolled nationwide in Korea with the suicidality module of the Mini-International Neuropsychiatric Interview (MINI) and the Depression and Somatic Symptom Scale (DSSS). On stepwise regression analysis, current suicidality scores were most strongly associated with chest pain in men, and neck or shoulder pain in women. Severe chest pain was associated with higher current suicidality scores in men than in women, whereas severe neck or shoulder pain showed no significant differences between the genders. In conclusion, MDD patients of both sexes with suicidal ideation showed significantly more frequent and severe somatic symptoms than those without. Current suicidal risk was associated with chest pain in men, and neck or shoulder pain in women. We suggest that clinicians pay attention to patients' somatic symptoms in real world practice.

Dementia is a chronic disease that requires both medical and social services to provide high quality of care and prevent complications. As a result of time constraints in practice, lack of systems-based approaches, and poor integration of community-based organizations (CBOs), the quality of care for dementia is poor compared to other diseases that affect older persons. The UCLA Alzheimer’s and Dementia Care (UCLA ADC) program partners with CBOs to provide comprehensive, coordinated, patient-centered care for patients with Alzheimer’s disease and other dementias. The goals of the program are to maximize patient function, independence and dignity, minimize caregiver strain and burnout and reduce unnecessary costs. The UCLA ADC program consists of five key components: patient recruitment and a dementia registry, structured needs assessments of patients in the registry and their caregivers, creation and implementation of individualized dementia care plans based on needs assessments and input from the primary care physicians, monitoring and revising care plans, as needed, and access 24/7, 365 days a year for assistance and advice. The program uses a co-management model with a nurse practitioner Dementia Care Manager working with primary care physicians and CBOs. Based on the first 150 patients served, the most common recommendations in the initial care plans were referrals to support groups (73%), Alzheimer’s Association Safe Return (73%), caregiver training (45%), and medication adjustment (41%). The program will be evaluated on its ability to achieve the triple aim of better care for individuals, better health for populations, and lower costs. PMID:24329821

PURPOSE The aim of this study was to evaluate the interface accuracy of computer-assisted designed and manufactured (CAD/CAM) titanium abutments and implant fixture compared to gold-cast UCLA abutments. MATERIALS AND METHODS An external connection implant system (Mark III, n=10) and an internal connection implant system (Replace Select, n=10) were used, 5 of each group were connected to milled titanium abutment and the rest were connected to the gold-cast UCLA abutments. The implant fixture and abutment were tightened to torque of 35 Ncm using a digital torque gauge, and initial detorque values were measured 10 minutes after tightening. To mimic the mastication, a cyclic loading was applied at 14 Hz for one million cycles, with the stress amplitude range being within 0 N to 100 N. After the cyclic loading, detorque values were measured again. The fixture-abutment gaps were measured under a microscope and recorded with an accuracy of ±0.1 µm at 50 points. RESULTS Initial detorque values of milled abutment were significantly higher than those of cast abutment (P<.05). Detorque values after one million dynamic cyclic loadings were not significantly different (P>.05). After cyclic loading, detorque values of cast abutment increased, but those of milled abutment decreased (P<.05). There was no significant difference of gap dimension between the milled abutment group and the cast abutment group after cyclic loading. CONCLUSION In conclusion, CAD/CAM milled titanium abutment can be fabricated with sufficient accuracy to permit screw joint stability between abutment and fixture comparable to that of the traditional gold cast UCLA abutment.

While the primary objective of joint arthroplasty is to improve patient quality of life, pain, and function, younger active patients often demand a return to higher function that includes sporting activity. Knowledge of rates and predictors of return to sports will help inform expectations in patients anticipating return to sports after joint arthroplasty. We measured the rate of sports participation at 1 year using the UCLA activity score and explored 11 variables, including choice of procedure/prosthesis, that might predict return to a high level of sporting activity, when controlling for potential confounding variables. We retrospectively evaluated 736 patients who underwent primary metal-on-polyethylene THA, metal-on-metal THA, hip resurfacing arthroplasty, revision THA, primary TKA, unicompartmental knee arthroplasty, and revision TKA between May 2005 and June 2007. We obtained UCLA activity scores on all patients; we defined high activity as a UCLA score of 7 or more. We evaluated patient demographics (age, sex, BMI, comorbidity), quality of life (WOMAC score, Oxford Hip Score, SF-12 score), and surgeon- and procedural/implant-specific variables to identify factors associated with postoperative activity score. Minimum followup was 11 months (mean, 12.1 months; range, 11-13 months). Preoperative UCLA activity score, age, male sex, and BMI predicted high activity scores. The type of operation and implant characteristics did not predict return to high activity sports. Our data suggest patient-specific factors predict postoperative activity rather than factors specific to type of surgery, implant, or surgeon factors. Level II, prognostic study.

Clinical measurement. Currently there are no self-report questionnaires in Thai to evaluate disability levels in patients suffering from upper extremity musculoskeletal disorders. To translate and cross-cultural adaptation the disabilities of the arm, shoulder and hand (DASH) questionnaire to Thai version and to evaluate content validity, construct validity and internal consistency of the questionnaire. The DASH-TH was produced by following cross-cultural adaptation guidelines stated by the Institute for Work and Health (IWH). Forty Thai patients with arm, shoulder or hand problems participated in field testing of the questionnaire. Content validity was determined by obtaining the item-objective congruence (IOC) value for each questionnaire item. Correlation between the DASH-TH score and numeric rating scale was used to assess construct validity. Internal consistency of DASH-TH was measured using Cronbach's alpha coefficient. Forty patients (14 males, 26 females) with arm, shoulder or hand problems enrolled in the present study. The average age of patients was 44.8 years. The index of item-objective congruence (IOC) of each item ranged from 0.7 to 1.0. The Cronbach's alpha coefficient of the questionnaire was 0.938. There was no correlation between DASH-TH score and numeric rating scale. The DASH-TH has high content validity and internal consistency. N/A. Copyright © 2014 Hanley & Belfus.

The objective of this study was to prospectively evaluate whether intraarticular anesthesia can reduce pain after MR or CT arthrography of the shoulder. This study included 120 patients who underwent CT or MR arthrography of the shoulder. The patients were randomized into two groups: the study group (n = 60), each administered an intraarticular injection of the contrast agent mixed with a local anesthetic (2% mepivacaine); and the control group (n = 60), each injected with the contrast agent only. Each patient's pain level was assessed at five phases-baseline and immediately, 2 hours, 1 day, and 2 days after injection-by using a visual analog scale or a verbal rating scale. The net pain score at each phase was also calculated. The pain course and net pain score were compared between study and control groups by repeated-measures analysis of variance. After the patients were divided into subgroups according to patient- or procedure-related factors, the efficacy of the intraarticular local anesthetic in each subgroup was evaluated. The pain course showed a quadratic trend and was not significantly different between study and control groups. The net pain score also was not significantly different between the two groups. No subgroup showed a significantly different efficacy of the intraarticular local anesthetic between the two groups. Intraarticular local anesthesia did not reduce arthrography-related pain.

Emotion dysregulation has been linked to binge eating disorder (BED) and bulimia nervosa (BN) although the mechanisms by which it affects BN/BED psychopathology are unclear. This study tested loneliness as a mediator between emotion dysregulation and BN/BED psychopathology. A treatment-seeking sample of 107 women with BN or BED was assessed for loneliness (UCLA Loneliness Scale), emotion dysregulation (Difficulties in Emotion Regulation Scale), and BN/BED psychopathology (Eating Disorder Examination) before treatment. Hierarchical linear regressions and bootstrapping mediation models were run. Greater overall emotion dysregulation was associated with greater BN/BED psychopathology, mediated by loneliness (95 % CI 0.03, 0.09). Emotion dysregulation, however, did not mediate between loneliness and BN/BED psychopathology (95 % CI −0.01, 0.01). Targeting loneliness may effectively treat emotional aspects of BN/BED in women.

Experiential avoidance (EA) involves the unwillingness to remain in contact with aversive experiences such as painful feelings, thoughts, and emotions. EA is often associated with the development and maintenance of emotional problems. Since loneliness is characterized by negative emotions such as sadness and pessimism, which is often linked to emotional problems, this study aims to test the mediating effects of EA on the relationship between emotion regulation abilities (ERA) and loneliness in a sample of Chinese adults. Five hundred undergraduates completed questionnaires measuring EA (Acceptance and Action Questionnaire; AAQ-Ⅱ), ERA (Failure-relate action orientation; Action Control Scale, ACS-90) and loneliness (UCLA Loneliness Scale). Structural equation modeling showed that EA fully-mediated the relationship between ERA and loneliness. The findings suggest EA is a key mechanism in explaining why people with high ERA are prone to feeling lower levels of loneliness. In particular, these findings have important implications for designing effective psychological interventions for loneliness.

Work-related musculoskeletal disorders are increasing due to industrialisation of work processes. Task variation has been suggested as potential intervention. The objectives of this study were to investigate, first, the influence of task variation on electromyographic (EMG) manifestations of shoulder muscle fatigue and discomfort; second, noticeable postural shoulder changes over time; third, if the association between task variation and EMG might be biased by postural changes. Outcome parameters were recorded using multichannel EMG, Optotrak and the Borg scale. Fourteen participants performed a one-hour repetitive Pegboard task in one continuous and two interrupted conditions with rest and a pick-and-place task, respectively. Manifestations of shoulder muscle fatigue and discomfort feelings were observed throughout the conditions but these were not significantly influenced by task variation. After correction for joint angles, the relation between task variation and EMG was significantly biased but significant effects of task variation remained absent. Comparing a one-hour continuous, repetitive Pegboard task with two interrupted conditions revealed no significant influences of task variation. We did observe that the relation between task variation and EMG was biased by posture and therefore advise taking account for posture when investigating manifestations of muscle fatigue in assembly tasks.

This is a randomized comparative study of the efficacy of celecoxib and loxoprofen in patients with frozen shoulder (scapulohumeral periarthritis). Patients with frozen shoulder who presented with pain as the symptom were divided at random into a celecoxib treatment group (100 mg/dose, twice daily; n = 37) and a loxoprofen treatment group (60 mg/dose, 3 times daily; n = 33). Medication was continued for 1-2 weeks in each group. Each patient was asked to rate the pain on a visual analog scale (score 0-5). This score significantly improved (indicating marked alleviation of pain) in both the celecoxib group (from 3.41 ± 0.86 before treatment to 2.30 ± 1.02 after treatment) and the loxoprofen group (from 3.73 ± 0.67 before treatment to 2.76 ± 0.96 after treatment). In the analysis of disappearance of pain, the percentage of patients showing disappearance of nocturnal pain was significantly higher in the celecoxib group (71.4 %) than in the loxoprofen group (36.8 %). The results confirm that celecoxib is comparable to loxoprofen in terms of analgesic efficacy in patients with frozen shoulder. Among other findings, we report that celecoxib was more effective for nocturnal pain than loxoprofen.

Ketamine has anti-inflammatory, analgesic and antihyperalgesic effect and prevents pain associated with wind-up. We investigated whether low doses of ketamine infusion during general anesthesia combined with single-shot interscalene nerve block (SSISB) would potentiate analgesic effect of SSISB. Forty adult patients scheduled for elective arthroscopic shoulder surgery were enrolled and randomized to either the control group or the ketamine group. All patients underwent SSISB and followed by general anesthesia. During an operation, intravenous ketamine was infused to the patients of ketamine group continuously. In control group, patients received normal saline in volumes equivalent to ketamine infusions. Pain score by numeric rating scale was similar between groups at 1, 6, 12, 24, 36, and 48 hr following surgery, which was maintained lower than 3 in both groups. The time to first analgesic request after admission on post-anesthesia care unit was also not significantly different between groups. Intraoperative low dose ketamine did not decrease acute postoperative pain after arthroscopic shoulder surgery with a preincisional ultrasound guided SSISB. The preventive analgesic effect of ketamine could be mitigated by SSISB, which remains one of the most effective methods of pain relief after arthroscopic shoulder surgery.

The purposes of this study were (1) to assess the construct validity of the Shoulder Pain and Disability Index (SPADI) and (2) to determine whether the SPADI is more responsive than the Sickness Impact Profile (SIP), a generic health status measure. The sample consisted of 94 patients who were diagnosed with a shoulder problem and referred to six outpatient physical therapy clinics. Clinically meaningful change was determined by use of an ordinal rating scale designed to determine whether the patient's shoulder function was improved, the same, or worse following treatment. Spearman rho correlations were calculated for the initial visit SPADI and SIP scores. The standardized response mean (SRM) was used to measure responsiveness for the patients who were judged to be improved. One-tailed paired t tests (alpha = .01) were used to determine whether differences existed among SRM values. Correlations between the SPADI and SIP scores ranged from r = .01 to r = .57. The SRM value was higher for the SPADI total score (SRM = 1.38) than for the SIP total score (SRM = 0.79). Most correlations between SPADI and SIP scores provided support for the construct validity of the SPADI. The SPADI does not appear to strongly reflect occupational and recreational disability and is more responsive than the SIP.

2017-12-01

UCLA Health embarked to transform care by integrating lean methodology in a key clinical project, Readmission Reduction Initiative (RRI). The first step focused on assembling a leadership team to articulate system-wide priorities for quality improvement. The lean principle of creating a culture of change and accountability was established by: 1) engaging stakeholders, 2) managing the process with performance accountability, and, 3) delivering patient-centered care. The RRI utilized three major lean principles: 1) A3, 2) root cause analyses, 3) value stream mapping. Baseline readmission rate at UCLA from 9/2010-12/2011 illustrated a mean of 12.1%. After the start of the RRI program, for the period of 1/2012-6/2013, the readmission rate decreased to 11.3% (p<0.05). To impact readmissions, solutions must evolve from smaller service- and location-based interventions into strategies with broader approach. As elucidated, a systematic clinical approach grounded in lean methodologies is a viable solution to this complex problem. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of this study was to perform a systematic review, meta-analysis, and meta-regression of all Level I and Level II studies comparing the clinical or structural outcomes, or both, after rotator cuff repair with and without platelet-rich product (PRP) supplementation. A literature search of the PubMed and EMBASE databases was performed to identify all Level I or II studies comparing the clinical or structural outcomes, or both, after arthroscopic repair of full-thickness rotator cuff tears with (PRP+ group) and without (PRP- group) PRP supplementation. Data included outcome scores (American Shoulder and Elbow Surgeons [ASES], University of California Los Angeles [UCLA], Constant, Simple Shoulder Test [SST] and visual analog scale [VAS] scores) and retears diagnosed with imaging studies. Meta-analyses compared preoperative, postoperative, and gain in outcome scores and relative risk ratios for retears. Meta-regression compared the effect of PRP treatment on outcome scores and retear rates according to 6 covariates. Minimum effect sizes that were detectable with 80% power were also calculated for each study. Eleven studies were included in this review and a maximum of 8 studies were used for meta-analyses according to data availability. There were no statistically significant differences between the PRP+ and PRP- groups for overall outcome scores or retear rates (P > .05). Overall gain in the Constant score was decreased when liquid PRP was injected over the tendon surface compared with PRP application at the tendon-bone interface (-6.88 points v +0.78 points, respectively; P = .046); however, this difference did not reach the previously reported minimum clinically important difference (MCID) for Constant scores. When the initial tear size was greater than 3 cm in anterior-posterior length, the PRP+ group exhibited decreased retear rates after double-row repairs when compared with the PRP- group (25.9% v 57.1%, respectively; P = .046). Sensitivity power analyses revealed that most included studies were only powered to detect large differences in outcome scores between groups. There were no statistically significant differences in overall gain in outcome scores or retear rates between treatment groups. Gain in Constant scores was significantly increased when PRPs were applied at the tendon-bone interface when compared with application over the top of the repaired tendon. Retear rates were significantly decreased when PRPs were used for the treatment of tears greater than 3 cm in anterior-posterior length using a double-row technique. Most of the included studies were only powered to detect large differences in outcome scores between treatment groups. In addition, an increased risk for selection, performance, and attrition biases was found. Level II, meta-analysis of Level I and Level II studies.

The project objective was to understand mechanisms by which atmosphere-land-ocean processes impact precipitation in the mean climate and interannual variations, focusing on tropical and subtropical regions. A combination of modeling tools was used: an intermediate complexity land-atmosphere model developed at UCLA known as the QTCM and the NASA Seasonal-to-Interannual Prediction Program general circulation model (NSIPP GCM). The intermediate complexity model was used to develop hypotheses regarding the physical mechanisms and theory for the interplay of large-scale dynamics, convective heating, cloud radiative effects and land surface feedbacks. The theoretical developments were to be confronted with diagnostics from the more complex GCM to validate or modify the theory.

OBJECTIVE: To translate, to perform a cultural adaptation of and to test the reproducibility of the Cochin Hand Functional Scale questionnaire for Brazil. METHODS: First, the Cochin Hand Functional Scale questionnaire was translated into Portuguese and was then back-translated into French. These translations were reviewed by a committee to establish a Brazilian version of the questionnaire to be tested. The validity and reproducibility of the Cochin Hand Functional Scale questionnaire was evaluated. Patients of both sexes, who were aged 18 to 60 years and presented with rheumatoid arthritis affecting their hands, were interviewed. The patients were initially interviewed by two observers and were later interviewed by a single rater. First, the Visual Analogue Scale for hand pain, the Arm, Shoulder and Hand Disability questionnaire and the Health Assessment Questionnaire were administered. The third administration of the Cochin Hand Functional Scale was performed fifteen days after the first administration. Ninety patients were assessed in the present study. RESULTS: Two questions were modified as a result of the assessment of cultural equivalence. The Cronbach's alpha value for this assessment was 0.93. The intraclass intraobserver and interobserver correlation coefficients were 0.76 and 0.96, respectively. The Spearman's coefficient indicated that there was a low level of correlation between the Cochin Hand Functional Scale and the Visual Analogue Scale for pain (0.46) and that there was a moderate level of correlation of the Cochin Scale with the Health Assessment Questionnaire (0.66) and with the Disability of the Arm, Shoulder and Hand questionnaire (0.63). The average administration time for the Cochin Scale was three minutes. CONCLUSION: The Brazilian version of the Cochin Hand Functional Scale was successfully translated and adapted, and this version exhibited good internal consistency, reliability and construct validity.

The 12-layer UCLA general circulation model encompassing troposphere and stratosphere (and superjacent 'sponge layer') is described. Prognostic variables are: surface pressure, horizontal velocity, temperature, water vapor and ozone in each layer, planetary boundary layer (PBL) depth, temperature, moisture and momentum discontinuities at PBL top, ground temperature and water storage, and mass of snow on ground. Selection of space finite-difference schemes for homogeneous incompressible flow, with/without a free surface, nonlinear two-dimensional nondivergent flow, enstrophy conserving schemes, momentum advection schemes, vertical and horizontal difference schemes, and time differencing schemes are discussed.

The number of arthroscopic rotator cuff surgeries is consistently increasing. Although generally considered successful, the reported number of retears after rotator cuff repair is substantial. Short-term clinical outcomes are reported to be rarely impaired by tendon retears, whereas to our knowledge, there is no study documenting long-term clinical outcomes and tendon integrity after arthroscopic rotator cuff repair. To investigate longitudinal long-term repair integrity and clinical outcomes after arthroscopic rotator cuff reconstruction. Case series; Level of evidence, 4. Thirty patients who underwent arthroscopic rotator cuff repair with suture anchors for a full-tendon full-thickness tear of the supraspinatus or a partial-tendon full-thickness tear of the infraspinatus were included. Two and 10 years after initial arthroscopic surgery, tendon integrity was analyzed using magnetic resonance imaging (MRI). The University of California, Los Angeles (UCLA) score and Constant score as well as subjective questions regarding satisfaction with the procedure and return to normal activity were used to evaluate short- and long-term outcomes. At the early MRI follow-up, 42% of patients showed a full-thickness rerupture, while 25% had a partial rerupture, and 33% of tendons remained intact. The 10-year MRI follow-up (129 ± 11 months) showed 50% with a total rerupture, while the other half of the tendons were partially reruptured (25%) or intact (25%). The UCLA and Constant scores significantly improved from preoperatively (UCLA total: 50.6% ± 20.2%; Constant total: 44.7 ± 10.5 points) to 2 years (UCLA total: 91.4% ± 16.0% [ P < .001]; Constant total: 87.8 ± 15.3 points [ P < .001]) and remained significantly higher after 10 years (UCLA total: 89.7% ± 15.9% [ P < .001]; Constant total: 77.5 ± 15.6 points [ P < .001]). The Constant total score and Constant strength subscore, but not the UCLA score, were also significantly better at 10 years postoperatively in patients with intact tendons compared with patients with retorn tendons (Constant total: 89.0 ± 7.8 points vs 75.7 ± 14.1 points, respectively [ P = .034]; Constant strength: 18.0 ± 4.9 points vs 9.2 ± 5.2 points, respectively [ P = .006]). The majority of patients rated their satisfaction with the procedure as "excellent" (83.3%), and 87.5% returned to their normal daily activities. Arthroscopic rotator cuff repair showed good clinical long-term results despite a high rate of retears. Nonetheless, intact tendons provided significantly superior clinical long-term outcomes, making the improvement of tendon healing and repair integrity important goals of future research efforts.

To assess the effectiveness of joint mobilization combined with stretching exercises in patients with frozen shoulder. A randomized controlled clinical pilot trial. Department of Orthopedics and Traumatology. Thirty patients with frozen shoulder. All participants were randomly assigned to one of two treatment groups: joint mobilization and stretching versus stretching exercises alone. Both groups performed a home exercise program and were treated for six weeks (18 sessions). The primary outcome measures for functional assessment were the Disabilities of the Arm, Shoulder and Hand score and the Constant score. The secondary outcome measures were pain level, as evaluated with a visual analog scale, and range of motion, as measured using a conventional goniometer. Patients were assessed before treatment, at the end of the treatment, and after one year as follow-up. Two-by-two repeated-measures ANOVA with Bonferroni corrections revealed significant increases in abduction (91.9° [CI: 86.1-96.7] to 172.8° [CI: 169.7-175.5]), external rotation (28.1° [CI: 22.2-34.2] to 77.7° [CI: 70.3-83.0]) and Constant score (39.1 [CI: 35.3-42.6] to 80.5 [75.3-86.6]) at the one-year follow-up in the joint mobilization combined with stretching exercise group, whereas the group performing stretching exercise alone did not show such changes. In the treatment of patients with frozen shoulder, joint mobilization combined with stretching exercises is better than stretching exercise alone in terms of external rotation, abduction range of motion and function score. © The Author(s) 2015.

[Manual trigger point therapy of shoulder pain : Randomized controlled study of effectiveness].

Although chronic shoulder pain is highly prevalent and myofascial trigger points (mTrP) are thought to be found in the majority of patients with shoulder complaints, the influence on the pain mechanism remains unclear. There are only very few controlled clinical studies on the effects of manual trigger point compression therapy. This randomized controlled trial (RCT) compared the short-term effects of manual trigger point compression therapy (n = 6) with manual sham therapy (n = 6) in patients with unilateral shoulder pain due to myofascial syndrome (MFS). The measurement data were collected before and after two sessions of therapy. Pressure pain thresholds (PPT) of mTrP and symmetrically located points on the asymptomatic side were measured together with neutral points in order to detect a potential unilateral or generalized hyperalgesia. Additionally, the pain was assessed on a visual analog scale (VAS) at rest and during movement and the neck disability index (NDI) and disabilities of the arm, shoulder and hand (DASH) questionnaires were also completed and evaluated. Both treatment modalities led to a significant improvement; however, the manual trigger point compression therapy was significantly more effective in comparison to sham therapy, as measured by different parameters. The significant improvement of PPT values in the interventional group even at sites that were not directly treated, indicates central mechanisms in pain threshold modulation induced by manual compression therapy. The weaker but still measurable effects of sham therapy might be explained by the sham modality being a hands on technique or by sufficient stimulation of the trigger point region during the diagnostics and PPT measurements.

The purpose of this study was to examine the effects of task-oriented electromyography-triggered stimulation for shoulder subluxation, muscle activation, pain and upper extremity function in hemiparetic stroke patients. Twenty participants with subacute hemiparetic stroke were recruited for this study and were randomly divided into two groups: experimental group (n = 10) and control group (n = 10). Subjects in the experimental group participated in task-oriented electromyography triggered stimulation for 30 minutes, five times a week for four weeks, whereas the control group received cyclic functional electrical stimulation for 30 minutes, five times a week for four weeks. Subjects in both groups received conventional physical therapy for four weeks (30 min/day, five times/week). Data collected included the degree of shoulder subluxation which had been confirmed by X-ray, muscle activation of the supraspinatus and posterior deltoid muscles by electromyography, pain by the Visual Analogue Scale (VAS), and hand function by the Fugl-Meyer Assessment (FMA) before and after the four week exercise period. The results showed significant improvement in shoulder subluxation, muscle activation, and VAS results in the experimental group, compared with the control group(p < 0.05). FMA scores showed no significant differences between the two groups. In conclusion, task-oriented electromyography-triggered stimulation improved shoulder subluxation, muscle activation, pain and upper extremity function. These results suggest that task-oriented electromyography-triggered stimulation is effective and beneficial for individuals with subacute stroke, and that further studies should be conducted on multivarious anatomical regions.

Many patients with rotator cuff tears suffer from nocturnal shoulder pain, resulting in sleep disturbance. To determine whether rotator cuff tear size correlated with sleep disturbance in patients with full-thickness rotator cuff tears. Cross-sectional study; Level of evidence, 3. Patients with a diagnosis of unilateral full-thickness rotator cuff tears (diagnosed via magnetic resonance imaging [MRI]) completed the Pittsburgh Sleep Quality Index (PSQI), a visual analog scale (VAS) quantifying their shoulder pain, and the American Shoulder and Elbow Surgeons (ASES) questionnaire. Shoulder MRI scans were analyzed for anterior-posterior tear size (mm), tendon retraction (mm), Goutallier grade (0-4), number of tendons involved (1-4), muscle atrophy (none, mild, moderate, or severe), and humeral head rise (present or absent). Bivariate correlations were calculated between the MRI characteristics and baseline survey results. A total of 209 patients with unilateral full-thickness rotator cuff tears were included in this study: 112 (54%) female and 97 (46%) male (mean age, 64.1 years). On average, shoulder pain had been present for 24 months. The mean PSQI score was 9.8, and the mean VAS score was 5.0. No significant correlations were found between any of the rotator cuff tear characteristics and sleep quality. Only tendon retraction had a significant correlation with pain. Although rotator cuff tears are frequently associated with nocturnal pain and sleep disruption, this study demonstrated that morphological characteristics of full-thickness rotator cuff tears, such as size and tendon retraction, do not correlate with sleep disturbance and have little to no correlation with pain levels.

Abstract Context: The overhead throwing motion is complex, and restrictions in range of motion (ROM) at the hip may place additional demands on the shoulder that lead to injury. However, the relationship between hip and shoulder ROM in athletes with and without a history of shoulder injury is unknown. Objective: To (1) determine if differences exist in hip and shoulder ROM between professional baseball players with a history of shoulder injury and those with no history of shoulder injury and (2) assess relationships between hip and shoulder ROM in these players. Design: Cross-sectional study. Patients or Other Participants: Fifty-seven professional baseball players. Main Outcome Measure(s): Outcome measures consisted of hip extension and internal rotation, shoulder internal and external rotation, glenohumeral internal-rotation deficit, and history of shoulder injury. Differences in shoulder and hip ROM were assessed with a 1-way analysis of variance. Associations between hip and shoulder ROM were assessed with linear regression. Results: Nonpitchers with a history of shoulder injury had more external rotation and less internal rotation of the shoulder than nonpitchers with no history of shoulder injury. Glenohumeral internal-rotation deficit was greater in both pitchers and nonpitchers with a history of shoulder injury. The relationship between dominant hip extension and shoulder external rotation was significant for pitchers with a history of shoulder injury and nonpitchers with a history of shoulder injury. Conclusions: Shoulder injury may be associated with specific measures of hip and shoulder ROM, and hip extension and shoulder external rotation may be related in baseball players with a history of shoulder injury. Additional research is necessary to understand the specific mechanisms of shoulder injury in the throwing athlete. PMID:20210623

Metabolic syndrome is a constellation of medical conditions that arise from insulin resistance and abnormal adipose deposition and function. In patients with metabolic syndrome and De Quervain tenosynovitis this might affect the outcome of treatment by local corticosteroid injection. A total of 64 consecutive patients with De Quervain tenosynovitis and metabolic syndrome treated with corticosteroid injection were age- and sex-matched with 64 control patients without metabolic syndrome. The response to treatment, including visual analogue scale score for pain, objective findings consistent with De Quervain tenosynovitis (tenderness at first dorsal compartment, Finkelstein test result), and Disability of the Arm, Shoulder, and Hand score were assessed at 6, 12, and 24 weeks follow-up. Treatment failure was defined as persistence of symptoms or surgical intervention. Prior to treatment, patients with metabolic syndrome had mean initial pain visual analogue scale and Disability of the Arm, Shoulder, and Hand scores similar to those in the control group. The proportion of treatment failure in the metabolic syndrome group (43%) was significantly higher than that in the control group (20%) at 6 months follow-up. The pain visual analogue scale scores in the metabolic syndrome group were higher than the scores in the control group at the 12- and 24-week follow-ups. The Disability of the Arm, Shoulder, and Hand scores of the metabolic syndrome group were higher (more severe symptoms) than those of the control group at the 12- and 24-week follow-ups. Although considerable improvements in symptom severity and hand function will likely occur in patients with metabolic syndrome, corticosteroid injection for De Quervain tenosynovitis is not as effective in these patients compared with age- and sex-matched controls in terms of functional outcomes and treatment failure.

In fractured reservoirs in the basement of extensional basins, fault and fracture parameters like density, spacing and length distribution are key properties for modelling and prediction of reservoir properties and fluids flow. As only large faults are detectable using basin-scale geophysical investigations, these fine-scale parameters need to be inferred from faults and fractures in analogous rocks at the outcrop. In this study, we use the western shoulder of the Upper Rhine Graben as an outcropping analogue of several deep borehole projects in the basement of the graben. Geological regional data, DTM (Digital Terrain Model) mapping and outcrop studies with scanlines are used to determine the spatial arrangement of the faults from the regional to the reservoir scale. The data shows that: 1) The fault network can be hierarchized in three different orders of scale and structural blocks with a characteristic structuration. This is consistent with other basement rocks studies in other rifting system allowing the extrapolation of the important parameters for modelling. 2) In the structural blocks, the fracture network linked to the faults is linked to the interplay between rock facies variation linked to the rock emplacement and the rifting event.

Pain is a complex and subjective reality and can be magnified by nonorganic or nonanatomic sources. Multiple studies have demonstrated a correlation between psychological factors and patients' perceptions of musculoskeletal pain and disability. In addition, nonorganic findings as part of the physical examination are well and long recognized. The purpose of this study was to analyze the relationship between a shoulder examination test, palpation of the sternoclavicular joint (SCJ), and psychosocial conditions including chronic pain, depression, and anxiety. From June until October 2016, all new patients of 2 sports/shoulder fellowship-trained surgeons at an academic practice were screened for study enrollment. After their consent was obtained, patients were given a set of 5 surveys (Pain Catastrophizing Scale; Patient-Health Questionnaire 2; Pain Self-Efficacy Questionnaire; shortened Disabilities of the Arm, Shoulder and Hand questionnaire; and Shoulder Pain and Disability Index) to complete. The physician then completed a comprehensive standardized physical examination, with the examining physician being blinded to the patient's survey responses. Palpation of the SCJ was done with the examiner's thumbs and was accompanied by the question "Does this hurt?" If a positive pain response was given, clarification as to the correct side of the pain was made. A total of 132 patients were enrolled and completed the surveys and physical examination. Of the patients, 26 (19.7%) reported SCJ pain with SCJ palpation. Patients with and without confirmed pain on SCJ palpation had significantly different (P < .001) mean scores for all 5 surveys. A review of the medical histories between the 2 groups identified a significantly increased prevalence of chronic pain and mental health disorders, such as anxiety and depression, in SCJ palpation-positive patients. Patients who confirmed pain on SCJ palpation had significantly higher scores on various psychological surveys than those who denied pain on palpation, indicating that a portion of their pain was stemming from a nonorganic source. Inclusion of SCJ palpation during a routine shoulder or upper extremity physical examination may improve selection of treatment options for patients.

Rotator cuff tendinopathy (RCT) is a significant source of disability and loss of work. Platelet-rich plasma (PRP) has been suggested to be beneficial in the treatment of RCT. To investigate the effect of PRP injections on pain and shoulder functions in patients with chronic RCT. Randomized controlled trial; Level of evidence, 1. A total of 40 patients, 18 to 70 years of age, with (1) a history of shoulder pain for >3 months during overhead-throwing activities, (2) MRI findings of RCT or partial tendon ruptures, and (3) a minimum 50% reduction in shoulder pain with subacromial injections of an anesthetic were included in this placebo-controlled, double-blind randomized clinical trial. Patients were randomized into a PRP group (n = 20) or placebo group (n = 20). Patients received an ultrasound-guided injection into the subacromial space that contained either 5 mL of PRP prepared from autologous venous blood or 5 mL of saline solution. All patients underwent a 6-week standard exercise program. Outcome measures (Western Ontario Rotator Cuff Index [WORC], Shoulder Pain and Disability Index [SPADI], 100-mm visual analog scale [VAS] of shoulder pain with the Neer test, and shoulder range of motion) were assessed at baseline and at 3, 6, 12, and 24 weeks and 1 year after injection. Comparison of the patients revealed no significant difference between the groups in WORC, SPADI, and VAS scores at 1-year follow-up (P = .174, P = .314, and P = .904, respectively). Similar results were found at other assessment points. Within each group, the WORC, SPADI, and VAS scores showed significant improvements compared with baseline at all time points (P < .001). In the range of motion measures, there were no significant group × time interactions. At 1-year follow-up, a PRP injection was found to be no more effective in improving quality of life, pain, disability, and shoulder range of motion than placebo in patients with chronic RCT who were treated with an exercise program.

Deviant shoulder girdle movement is suggested as an eminent factor in the etiology of shoulder pain. Reliable measurements of shoulder girdle kinematics are a prerequisite for optimizing clinical management strategies. The purpose of this study was to evaluate the reliability, measurement error, and internal consistency of measurements with performance-based clinical tests for shoulder girdle kinematics and positioning in patients with shoulder pain. The MEDLINE, Embase, CINAHL, and SPORTDiscus databases were systematically searched from inception to August 2015. Articles published in Dutch, English, or German were included if they involved the evaluation of at least one of the measurement properties of interest. Two reviewers independently evaluated the methodological quality per studied measurement property with the 4-point-rating scale of the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) checklist, extracted data, and assessed the adequacy of the measurement properties. Forty studies comprising more than 30 clinical tests were included. Actual reported measurements of the tests were categorized into: (1) positional measurement methods, (2) measurement methods to determine dynamic characteristics, and (3) tests to diagnose impairments of shoulder girdle function. Best evidence synthesis of the tests was performed per measurement for each measurement property. All studies had significant limitations, including incongruence between test description and actual reported measurements and a lack of reporting on minimal important change. In general, the methodological quality of the selected studies was fair to poor. High-quality evidence indicates that measurements obtained with the Modified Scapular Assistance Test are not reliable for clinical use. Sound recommendations for the use of other tests could not be made due to inadequate evidence. Across studies, diversity in description, performance, and interpretation of similar tests was present, and different criteria were used to establish similar diagnoses, mostly without taking into account a clinically meaningful context. Consequently, these tests lack face validity, which hampers their clinical use. Further research on validity and how to integrate a clinically meaningful context of movement into clinical tests is warranted. © 2017 American Physical Therapy Association

This study was conducted to report loss of reduction and complications after single-tunnel coracoclavicular (CC) ligament reconstruction with autogenous semitendinosus tendon graft for acute acromioclavicular (AC) joint dislocations. This retrospective study included patients with acute, unstable AC dislocations (surgery within 6 weeks after trauma). We excluded patients with chronic injury and distal clavicle fractures with CC ligaments disruption. We measured the CC distance on anteroposterior radiographs of both clavicles, preoperatively, immediately postoperatively, and at the final follow-up visit. We evaluated clinical outcomes using the American Shoulder and Elbow Surgeons Shoulder Assessment and the University of California, Los Angeles Shoulder Rating Scale scores and perioperative complications. There were 30 patients (27 men and 3 women) with mean age of 41 years (range, 19-70 years). The mean follow-up period was 31 months (range, 12-186 months). Mean CC distance was 15.5 ± 3.7 mm (84% ± 14% of the contralateral shoulder) preoperatively, 8.9 ± 2.6 mm (9% ± 40%) immediately postoperatively (P < .001), and 10.6 ± 3.3 mm (24% ± 39%) at the final assessment (P < .001), showing an increase of the CC distance during the follow-up. Loss of reduction (defined as >25% increase of CC distance) developed in 14 patients (47%), and complications occurred in 6 patients (20%), including 3 distal clavicle fractures through the tunnel. Final clinical scores were significantly lower in patients with complications (27 vs. 33 of the University of California, Los Angeles assessment [P < .001] and 81 vs. 95 of the American Shoulder and Elbow Surgeons Shoulder assessment [P < .001]). In acute AC joint dislocation, single-tunnel CC ligament reconstruction using autogenous tendon graft resulted in loss of reduction rate of 47% and a complication rate of 20%. The development of complications adversely affected clinical outcomes. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc. All rights reserved.

Objective: To estimate the extent to which psychophysical quantitative sensory test (QST) and patient factors (gender, age and comorbidity) predict pain, function and health status in people with shoulder disorders. To determine if there are gender differences for QST measures in current perception threshold (CPT), vibration threshold (VT) and pressure pain (PP) threshold and tolerance. Design: A cross-sectional study design. Setting: MacHAND Clinical Research Lab at McMaster University. Subjects: 34 surgical and 10 nonsurgical participants with shoulder pain were recruited. Method: Participants completed the following patient reported outcomes: pain (Numeric Pain Rating, Pain Catastrophizing Scale, Shoulder Pain and Disability Index) and health status (Short Form-12). Participants completed QST at 4 standardized locations and then an upper extremity performance-based endurance test (FIT-HaNSA). Pearson r’s were computed to determine the relationships between QST variables and patient factors with either pain, function or health status. Eight regression models were built to analysis QST’s and patient factors separately as predictors of either pain, function or health status. An independent sample t-test was done to evaluate the gender effect on QST. Results: Greater PP threshold and PP tolerance was significantly correlated with higher shoulder functional performance on the FIT-HANSA (r =0.31-0.44) and lower self-reported shoulder disability (r = -0.32 to -0.36). Higher comorbidity was consistently correlated (r =0.31-0.46) with more pain, and less function and health status. Older age was correlated to more pain intensity and less function (r =0.31-0.57). In multivariate models, patient factors contributed significantly to pain, function or health status models (r2 =0.19-0.36); whereas QST did not. QST was significantly different between males and females [in PP threshold (3.9 vs. 6.2, p < .001) and PP tolerance (7.6 vs. 2.6, p < .001) and CPT (1.6 vs. 2.3, p =.02)]. Conclusion: Psychophysical dimensions and patient factors (gender, age and comorbidity) affect self-reported and performance-based outcome measures in people with shoulder disorders. PMID:29399220

Convex Clustering: An Attractive Alternative to Hierarchical Clustering

2015-01-01

The primary goal in cluster analysis is to discover natural groupings of objects. The field of cluster analysis is crowded with diverse methods that make special assumptions about data and address different scientific aims. Despite its shortcomings in accuracy, hierarchical clustering is the dominant clustering method in bioinformatics.

Dizziness and unsteadiness are common symptoms following a whiplash injury. To compare the effect of 3 exercise programs on balance, dizziness, proprioception and pain in patients with chronic whiplash complaining of dizziness. A sub-analysis of a randomized study. One hundred and forty subjects were randomized to either a physiotherapist-guided neck-specific exercise (NSE), physiotherapist-guided neck-specific exercise, with a behavioural approach (NSEB) or prescription of general physical activity (PPA) group. Pre intervention, 3, 6 and 12 months post baseline they completed the University of California Los Angeles Dizziness Questionnaire (UCLA-DQ), Visual Analogue Scales (VAS) for, dizziness at rest and during activity and physical measures (static and dynamic clinical balance tests and head repositioning accuracy (HRA)). There were significant time by group differences with respect to dizziness during activity and UCLA-Q favouring the physiotherapy led neck specific exercise group with a behavioural approach. Within group analysis of changes over time also revealed significant changes in most variables apart from static balance. Between and within group comparisons suggest that physiotherapist led neck exercise groups including a behavioural approach had advantages in improving measures of dizziness compared with the general physical activity group, although many still complained of dizziness and balance impairment. Future studies should consider exercises specifically designed to address balance, dizziness and cervical proprioception in those with persistent whiplash. Crown Copyright © 2015.

The primary goal in cluster analysis is to discover natural groupings of objects. The field of cluster analysis is crowded with diverse methods that make special assumptions about data and address different scientific aims. Despite its shortcomings in accuracy, hierarchical clustering is the dominant clustering method in bioinformatics. Biologists find the trees constructed by hierarchical clustering visually appealing and in tune with their evolutionary perspective.

Muscle strength and fatigue in newly diagnosed patients with myasthenia gravis.

PubMed

Vinge, Lotte; Andersen, Henning

2016-10-01

Dynamometry is increasingly used as an objective measurement of muscle strength in neurological diseases. No study has applied dynamometry in untreated newly diagnosed patients with myasthenia gravis (MG). Isometric muscle strength at the shoulder, knee, and ankle was determined in 21 MG patients before and after initial anti-myasthenic treatment. Isometric strength was compared with MG evaluation scales. Muscle strength was reduced for knee extensors and shoulder abductors but normal for ankle extensors. Isometric muscle strength did not correlate significantly with manual muscle testing (MG Composite). Dynamometry revealed improved muscle strength of up to 50% (median 17%; range -1.8-49.8) despite no change in the MG Composite score. Dynamometry appears to be a more sensitive method of identifying changes in limb strength than MG evaluation scales. This supports the use of dynamometry in MG patients, especially for evaluation of the effect of anti-myasthenic treatment. Muscle Nerve 54: 709-714, 2016. © 2016 Wiley Periodicals, Inc.

Frozen shoulder is a potential complication after shoulder surgery. It is a clinical condition that is often associated with marked disability and can have a profound effect on the patient's quality of life. The incidence, etiology, pathology and prognostic factors of postoperative frozen shoulder after shoulder surgery are not known. The purpose of this explorative study was to determine the incidence of postoperative frozen shoulder after various operative shoulder procedures. A second aim was to identify prognostic factors for postoperative frozen shoulder after shoulder surgery. 505 consecutive patients undergoing elective shoulder surgery were included in this prospective cohort study. Follow-up was 6 months after surgery. A prediction model was developed to identify prognostic factors for postoperative frozen shoulder after shoulder surgery using the TRIPOD guidelines. We nominated five potential predictors: gender, diabetes mellitus, type of physiotherapy, arthroscopic surgery and DASH score. Frozen shoulder was identified in 11% of the patients after shoulder surgery and was more common in females (15%) than in males (8%). Frozen shoulder was encountered after all types of operative procedures. A prediction model based on four variables (diabetes mellitus, specialized shoulder physiotherapy, arthroscopic surgery and DASH score) discriminated reasonably well with an AUC of 0.712. Postoperative frozen shoulder is a serious complication after shoulder surgery, with an incidence of 11%. Four prognostic factors were identified for postoperative frozen shoulder: diabetes mellitus, arthroscopic surgery, specialized shoulder physiotherapy and DASH score. The combination of these four variables provided a prediction rule for postoperative frozen shoulder with reasonable fit. Level II, prospective cohort study.

This study compared the removal torque values (RTVs) of different abutments (straight, angled, and gold premachined UCLA-type) in external- and internal-hex implants after dynamic cyclic loading with the clinical situation of the anterior maxilla simulated. An ideal cast of a maxilla with a missing right central incisor was fabricated in dental stone, and an implant analog was embedded in this model at a 15-degree angle labial to the long axis of the left central incisor. Thirty external-hex and 30 internal-hex implants were used. A total of 10 straight abutments, 10 angled abutments, and 10 gold premachined UCLA-type abutments of each system and 60 abutment screws were tested. Initial RTVs were measured after each assembly was tightened to 30 Ncm. Straight abutments and angled abutments were prepared and gold-premachined UCLA-type abutments were waxed and cast with low-fusing gold alloy for the central incisor. RTVs were then measured again. After each assembly was tightened, a metal crown was temporarily cemented. After cyclic loading of 20 to 200 N was applied 1 million times, RTVs were measured for a third time. Statistical analysis (alpha = .05) was performed to evaluate the results. The angled abutment group showed significantly higher RTVs than the straight abutment and gold premachined UCLA-type abutment groups in external-hex implants. However, no significant difference in RTVs was found among abutments in internal-hex implants. The time of analysis of RTV was found to significantly influence mean RTVs. Mean RTVs of external- and internal-hex implants showed significant differences. Within the limitations of this study, there were significant differences in RTVs among different abutment groups in external-hex implants. There were no significant differences in RTVs among different abutment groups in internal-hex implants.

Chronic pain is influenced by biological, psychological, social, and cultural factors. The current study investigated potential roles for combinations of genetic and psychological factors in the development and/or maintenance of chronic musculoskeletal pain. An exercise-induced shoulder injury model was used, and a priori selected genetic (ADRB2, COMT, OPRM1, AVPR1 A, GCH1, and KCNS1) and psychological (anxiety, depressive symptoms, pain catastrophizing, fear of pain, and kinesiophobia) factors were included as predictors. Pain phenotypes were shoulder pain intensity (5-day average and peak reported on numerical rating scale), upper extremity disability (5-day average and peak reported on the QuickDASH), and shoulder pain duration (in days). After controlling for age, sex, and race, the genetic and psychological predictors were entered as main effects and interaction terms in separate regression models for the different pain phenotypes. Results from the recruited cohort (N = 190) indicated strong statistical evidence for interactions between the COMT diplotype and 1) pain catastrophizing for 5-day average upper extremity disability and 2) depressive symptoms for pain duration. There was moderate statistical evidence for interactions for other shoulder pain phenotypes between additional genes (ADRB2, AVPR1 A, and KCNS1) and depressive symptoms, pain catastrophizing, or kinesiophobia. These findings confirm the importance of the combined predictive ability of COMT with psychological distress and reveal other novel combinations of genetic and psychological factors that may merit additional investigation in other pain cohorts. Interactions between genetic and psychological factors were investigated as predictors of different exercise-induced shoulder pain phenotypes. The strongest statistical evidence was for interactions between the COMT diplotype and pain catastrophizing (for upper extremity disability) or depressive symptoms (for pain duration). Other novel genetic and psychological combinations were identified that may merit further investigation. Copyright © 2014 American Pain Society. Published by Elsevier Inc. All rights reserved.

What factors are predictors of emotional health in patients with full-thickness rotator cuff tears?

2016-11-01

The importance of emotional and psychological factors in treatment of patients with rotator cuff disease has been recently emphasized. Our goal was to establish factors most predictive of poor emotional health in patients with full-thickness rotator cuff tears (FTRCTs). In 2007, we began to prospectively collect data on patients with symptomatic, atraumatic FTRCTs. All patients completed a questionnaire collecting data on demographics, symptom characteristics, comorbidities, willingness to undergo surgery, and patient-related outcomes (12-Item Short Form Health Survey, American Shoulder and Elbow Surgeons score, Western Ontario Rotator Cuff Index [WORC], Single Assessment Numeric Evaluation score, Shoulder Activity Scale). Physicians recorded physical examination and imaging data. To evaluate the predictors of lower WORC emotion scores, a linear multiple regression model was fit. Baseline data for 452 patients were used for analysis. In patients with symptomatic FTRCTs, the factors most predictive of worse WORC emotion scores were higher levels of pain (interquartile range odds ratio, -18.9; 95% confidence interval, -20.2 to -11.6; P < .0001) and lower Single Assessment Numeric Evaluation scores (rating of percentage normal that patients perceive their shoulder to be; interquartile range odds ratio, 6.2; 95% confidence interval, 2.5-9.95; P = .0012). Higher education (P = .006) and unemployment status (P = .0025) were associated with higher WORC emotion scores. Education level, employment status, pain levels, and patient perception of percentage of shoulder normalcy were most predictive of emotional health in patients with FTRCTs. Structural data, such astendon tear size, were not. Those with poor emotional health may perceive their shoulder to be worse than others and experience more pain. This may allow us to better optimize patient outcomes with nonoperative and operative treatment of rotator cuff tears. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

The ability to identify pitchers at risk for injury could be valuable to a professional baseball organization. To our knowledge, there have been no prior studies examining the predictive value of preseason strength measurements. Preseason weakness of shoulder external rotators is associated with increased risk of in-season throwing-related injury in professional baseball pitchers. Cohort study (prognosis); Level of evidence, 2. Preseason shoulder strength was measured for all pitchers in a professional baseball organization over a 5-year period (2001-2005). Prone internal rotation (IR), prone external rotation (PER), seated external rotation (SER), and supraspinatus (SS) strength were tested during spring training before each season. The players were then prospectively followed throughout the season for incidence of throwing-related injury. Injuries were categorized on an ordinal scale, with no injury, injury treated conservatively, and injury resulting in surgery delineated 0, 1, and 2, respectively. Subset analyses of shoulder injuries and of players with prior surgery were also performed. The association between strength measurements and injury was analyzed using Spearman rank correlation. A statistically significant association was observed for PER strength (P = .003), SER strength (P = .048), and SS strength (P = .006) with throwing-related injury requiring surgical intervention. Supraspinatus strength was also significantly associated with incidence of any shoulder injury (P = .031). There was an association between the ratio of PER/IR strength and incidence of shoulder injury (P = .037) and some evidence for an association with overall incidence of throwing-related injury (P = .051). No associations were noted in the subgroup of players with prior surgery. Preseason weakness of external rotation and SS strength is associated with in-season throwing-related injury resulting in surgical intervention in professional baseball pitchers. Thus, preseason strength data may help identify players at risk for injury and formulate strengthening plans for prevention.

Changes in social isolation and loneliness following total hip and knee arthroplasty: longitudinal analysis of the English Longitudinal Study of Ageing (ELSA) cohort.

2017-09-01

To determine the prevalence and change in social isolation and loneliness in people before and after total hip arthroplasty (THA) and total knee arthroplasty (TKA) in England. The English Longitudinal Study of Ageing (ELSA) dataset, a prospective study of community-dwelling older adults, was used to identify people who had undergone primary THA or TKA because of osteoarthritis. Social isolation was assessed using the ELSA Social Isolation Index. Loneliness was evaluated using the Revised University of California, Los Angeles (UCLA) Loneliness Scale. The prevalence of social isolation and loneliness were calculated and multilevel modelling was performed to assess the potential change of these measures before arthroplasty, within a two-year operative-recovery phase and a following two-year follow-up. The sample consisted of 393 people following THA and TKA. The prevalence of social isolation and loneliness changed from 16.9% to 18.8% pre-operative to 21.8% and 18.9% at the final post-operative follow-up respectively. This was not a statistically significant change for either measure (P = 0.15; P = 0.74). There was a significant difference in social isolation at the recovery phase compared to the pre-operative phase (P = 0.01), where people following arthroplasty reported an increase in social isolation (16.9-21.4%). There was no significant difference between the assessment phases in respect to UCLA Loneliness Scale score (P ≥ 0.74). Given the negative physical and psychological consequences which social isolation and loneliness can have on individuals following THA or TKA, clinicians should be mindful of this health challenge for this population. The reported prevalence of social isolation and loneliness suggests this is an important issue. Copyright © 2017 Osteoarthritis Research Society International. Published by Elsevier Ltd.

Replacing climatological potential evapotranspiration estimates with dynamic satellite-based observations in operational hydrologic prediction models

NASA Astrophysics Data System (ADS)

Franz, K. J.; Bowman, A. L.; Hogue, T. S.; Kim, J.; Spies, R.

2011-12-01

In the face of a changing climate, growing populations, and increased human habitation in hydrologically risky locations, both short- and long-range planners increasingly require robust and reliable streamflow forecast information. Current operational forecasting utilizes watershed-scale, conceptual models driven by ground-based (commonly point-scale) observations of precipitation and temperature and climatological potential evapotranspiration (PET) estimates. The PET values are derived from historic pan evaporation observations and remain static from year-to-year. The need for regional dynamic PET values is vital for improved operational forecasting. With the advent of satellite remote sensing and the adoption of a more flexible operational forecast system by the National Weather Service, incorporation of advanced data products is now more feasible than in years past. In this study, we will test a previously developed satellite-derived PET product (UCLA MODIS-PET) in the National Weather Service forecast models and compare the model results to current methods. The UCLA MODIS-PET method is based on the Priestley-Taylor formulation, is driven with MODIS satellite products, and produces a daily, 250m PET estimate. The focus area is eight headwater basins in the upper Midwest U.S. There is a need to develop improved forecasting methods for this region that are able to account for climatic and landscape changes more readily and effectively than current methods. This region is highly flood prone yet sensitive to prolonged dry periods in late summer and early fall, and is characterized by a highly managed landscape, which has drastically altered the natural hydrologic cycle. Our goal is to improve model simulations, and thereby, the initial conditions prior to the start of a forecast through the use of PET values that better reflect actual watershed conditions. The forecast models are being tested in both distributed and lumped mode.

Effectiveness of Trauma-Focused Cognitive Behavioral Therapy for Children and Adolescents: A Randomized Controlled Trial in Eight German Mental Health Clinics.

PubMed

Goldbeck, Lutz; Muche, Rainer; Sachser, Cedric; Tutus, Dunja; Rosner, Rita

Trauma-focused cognitive behavioral therapy (Tf-CBT) is efficacious for children and adolescents with posttraumatic stress symptoms (PTSS). Its effectiveness in clinical practice has still to be investigated. To determine whether Tf-CBT is superior to waiting list (WL), and to investigate the predictors of treatment response. We conducted a single-blind parallel-group randomized controlled trial in eight German outpatient clinics with the main inclusion criteria of age 7-17 years, symptom score ≥35 on the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA), and caregiver participation. Patients were randomly assigned to 12 sessions of Tf-CBT (n = 76) or a WL (n = 83). The primary outcome was the CAPS-CA symptom score assessed at 4 months by blinded evaluators. The secondary measures were diagnostic status, the Children's Global Assessment Scale (CGAS), self-reported and caregiver-reported PTSS (UCLA-PTSD Reaction Index), the Child Posttraumatic Cognitions Inventory (CPTCI), the Children's Depression Inventory (CDI), the Screen for Child Anxiety- Related Emotional Disorders (SCARED), the Child Behavior Checklist (CBCL/4-18), and the Quality of Life Inventory for Children. Intention-to-treat analyses showed that Tf-CBT was significantly superior to WL on the CAPS-CA (Tf-CBT: baseline = 58.51 ± 17.41; 4 months = 32.16 ± 26.02; WL: baseline = 57.39 ± 16.05; 4 months = 43.29 ± 25.2; F1, 157 = 12.3; p = 0.001; d = 0.50), in terms of secondary measures of the CGAS, UCLA-PTSD-RI, CPTCI, CDI, SCARED, and CBCL/4-18, but not in terms of quality of life. Age and comorbidity significantly predicted treatment response. Tf-CBT is effective for children and adolescents with heterogeneous trauma types in German service settings. Younger patients with fewer comorbid disorders show most improvement. © 2016 S. Karger AG, Basel.

Subacromial injection of autologous platelet-rich plasma versus corticosteroid for the treatment of symptomatic partial rotator cuff tears.

PubMed

Shams, Ahmed; El-Sayed, Mohamed; Gamal, Osama; Ewes, Waled

2016-12-01

Rotator cuff tears are one of the most common causes of chronic shoulder pain and disability. They significantly affect the quality of life. Reduced pain and improved function are the goals of conventional therapy, which includes relative rest, pain therapy, physical therapy, corticosteroid injections and surgical intervention. Tendons have a relative avascular nature; hence, their regenerative potential is limited. There is some clinical evidence that the application of autologous platelets may help to revascularize the area of injury in rotator cuff pathologies. This prospective randomized controlled study was done to evaluate the results of subacromial injection of platelet-rich plasma (PRP) versus corticosteroid injection therapy in 40 patients with symptomatic partial rotator cuff tears. All patients were assessed before injection, 6 weeks, 3 and 6 months after injection, using the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), the Constant-Murley Score (CMS), the Simple Shoulder Test (SST) and a Visual Analog Scale (VAS) for pain. An MRI was performed before and 6 months after the injection for all the included patients and was graded on 0-5 scale. Both injection groups showed statistically significantly better clinical outcomes over time compared with those before injection. There was a statistically significant difference between RPP group and corticosteroid group 12 weeks after injection, regarding VAS, ASES, CMS and SST in favor of the RPP group. MRI showed an overall slight nonsignificant improvement in grades of tendinopathy/tear in both groups, however, without statistically significant differences between the two groups. PRP injections showed earlier better results as compared to corticosteroid injections, although statistically significant better results after 6 months could not be found. Therefore, subacromial RPP injection could be considered as a good alternative to corticosteroid injection, especially in patients with a contraindication to corticosteroid administration. II.

Rasch Model Analysis Gives New Insights Into the Structural Validity of the QuickDASH in Patients With Musculoskeletal Shoulder Pain.

PubMed

Jerosch-Herold, Christina; Chester, Rachel; Shepstone, Lee

2017-09-01

Study Design Cross-sectional secondary analysis of a prospective cohort study. Background The shortened version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) is a widely used outcome measure that has been extensively evaluated using classical test theory. Rasch model analysis can identify strengths and weaknesses of rating scales and goes beyond classical test theory approaches. It uses a mathematical model to test the fit between the observed data and expected responses and converts ordinal-level scores into interval-level measurement. Objective To test the structural validity of the QuickDASH using Rasch analysis. Methods A prospective cohort study of 1030 patients with shoulder pain provided baseline data. Rasch analysis was conducted to (1) assess how the QuickDASH fits the Rasch model, (2) identify sources of misfit, and (3) explore potential solutions to these. Results There was evidence of multidimensionality and significant misfit to the Rasch model (χ 2 = 331.09, P<.001). Two items had disordered threshold responses with strong floor effects. Response bias was detected in most items for age and sex. Rescoring resulted in ordered thresholds; however, the 11-item scale still did not meet the expectations of the Rasch model. Conclusion Rasch model analysis on the QuickDASH has identified a number of problems that cannot be easily detected using traditional analyses. While revisions to the QuickDASH resulted in better fit, a "shoulder-specific" version is not advocated at present. Caution needs to be exercised when interpreting results of the QuickDASH outcome measure, as it does not meet the criteria for interval-level measurement and shows significant response bias by age and sex.

2017-08-01

The purpose of this study was to evaluate the functional outcomes of medialized rotator cuff repair and the continuity of repaired tendon in chronic retracted rotator cuff tears. Thirty-five consecutive patients were selected from 153 cases that underwent arthroscopic rotator cuff repair for more than medium-sized posterosuperior rotator cuff tears between July 2009 and July 2012 performed with the medialized repair. All cases were available for at least 2 years of postoperative follow-up. The visual analog scale of pain, muscle strength, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and University of California-Los Angeles score were evaluated. At the final follow-up, all clinical outcomes were significantly improved. The visual analog scale score for pain improved from 6 ± 1 preoperatively to 2 ± 1 postoperatively. The range of motion increased from preoperatively to postoperatively: active forward elevation, from 134° ± 49° to 150° ± 16°; active external rotation at the side, from 47° ± 15° to 55° ± 10°; and active internal rotation, from L3 to L1. The shoulder score also improved: Constant score, from 53.5 ± 16.7 to 79 ± 10; American Shoulder and Elbow Surgeons score, from 51 ± 15 to 82 ± 8; and University of California-Los Angeles score, from 14 ± 4 to 28 ± 4. The retear cases at the final follow-up were 6 (17%). Medialized repair may be useful in cases in which anatomic bone-to-tendon repair would be difficult because of the excessive tension of the repaired tendon and a torn tendon that does not reach the anatomic insertion.

To compare the effect of dextrose prolotherapy on pain levels and degenerative changes in painful rotator cuff tendinopathy against 2 potentially active control injection procedures. Randomized controlled trial, blinded to participants and evaluators. Outpatient pain medicine practice. Persons (N=73) with chronic shoulder pain, examination findings of rotator cuff tendinopathy, and ultrasound-confirmed supraspinatus tendinosis/tear. Three monthly injections either (1) onto painful entheses with dextrose (Enthesis-Dextrose), (2) onto entheses with saline (Enthesis-Saline), or (3) above entheses with saline (Superficial-Saline). All solutions included 0.1% lidocaine. All participants received concurrent programmed physical therapy. Primary: participants achieving an improvement in maximal current shoulder pain ≥2.8 (twice the minimal clinically important difference for visual analog scale pain) or not. Secondary: improvement in the Ultrasound Shoulder Pathology Rating Scale (USPRS) and a 0-to-10 satisfaction score (10, completely satisfied). The 73 participants had moderate to severe shoulder pain (7.0±2.0) for 7.6±9.6 years. There were no baseline differences between groups. Blinding was effective. At 9-month follow-up, 59% of Enthesis-Dextrose participants maintained ≥2.8 improvement in pain compared with Enthesis-Saline (37%; P=.088) and Superficial-Saline (27%; P=.017). Enthesis-Dextrose participants' satisfaction was 6.7±3.2 compared with Enthesis-Saline (4.7±4.1; P=.079) and Superficial-Saline (3.9±3.1; P=.003). USPRS findings were not different between groups (P=.734). In participants with painful rotator cuff tendinopathy who receive physical therapy, injection of hypertonic dextrose on painful entheses resulted in superior long-term pain improvement and patient satisfaction compared with blinded saline injection over painful entheses, with intermediate results for entheses injection with saline. These differences could not be attributed to a regenerative effect. Dextrose prolotherapy may improve on the standard care of painful rotator cuff tendinopathy for certain patients.

To identify the etiology of hemiplegic shoulder pain by arthrographic and clinical examinations and to determine the correlation between arthrographic measurements and clinical findings in patients with hemiplegic shoulder pain. Case series. Medical center of a 1582-bed teaching institution in Taiwan. Thirty-two consecutive patients with hemiplegic shoulder pain within a 1-year period after first stroke were recruited. Not applicable. Clinical examinations included Brunnstrom stage, muscle spasticity distribution, presence or absence of subluxation and shoulder-hand syndrome, and passive range of motion (PROM) of the shoulder joint. Arthrographic measurements included shoulder joint volume and capsular morphology. Most patients had onset of hemiplegic shoulder pain less than 2 months after stroke. Adhesive capsulitis was the main cause of shoulder pain, with 50% of patients having adhesive capsulitis, 44% having shoulder subluxation, 22% having rotator cuff tears, and 16% having shoulder-hand syndrome. Patients with adhesive capsulitis showed significant restriction of passive shoulder external rotation and abduction and a higher incidence of shoulder-hand syndrome (P=.017). Those with irregular capsular margins had significantly longer shoulder pain duration and more restricted passive shoulder flexion (P=.017) and abduction (P=.020). Patients with shoulder subluxation had significantly larger PROM (flexion, P=.007; external rotation, P<.001; abduction, P=.001; internal rotation, P=.027), lower muscle tone (P=.001), and lower Brunnstrom stages of the proximal upper extremity (P=.025) and of the distal upper extremity (P=.001). Muscle spasticity of the upper extremity was slightly negatively correlated with shoulder PROM. Shoulder joint volume was moderately positively correlated with shoulder PROM. After investigating the hemiplegic shoulder joint through clinical and arthrographic examinations, we found that the causes of hemiplegic shoulder pain are complicated. Adhesive capsulitis was the leading cause of shoulder pain, followed by shoulder subluxation. Greater PROM of the shoulder joint, associated with larger joint volume, decreased the occurrence of adhesive capsulitis. Proper physical therapy and cautious handling of stroke patients to preserve shoulder mobility and function during early rehabilitation are important for a good outcome.

To determine whether immobilization after arthroscopic rotator cuff repair improved tendon healing compared with early passive motion. A systematic electronic literature search was conducted to identify randomized controlled trials (RCTs) comparing early passive motion with immobilization after arthroscopic rotator cuff repair. The primary outcome assessed was tendon healing in the repaired cuff. Secondary outcome measures were range of motion (ROM) and American Shoulder and Elbow Surgeons (ASES) shoulder scale, Simple Shoulder Test (SST), Constant, and visual analog scale (VAS) for pain scores. Pooled analyses were performed using a random effects model to obtain summary estimates of treatment effect with 95% confidence intervals. Heterogeneity among included studies was quantified. Three RCTs examining 265 patients were included. Meta-analysis revealed no significant difference in tendon healing in the repaired cuff between the early-motion and immobilization groups. A significant difference in external rotation at 6 months postoperatively favored early motion over immobilization, but no significant difference was observed at 1 year postoperatively. In one study, Constant scores were slightly higher in the early-motion group than in the immobilization group. Two studies found no significant difference in ASES, SST, or VAS score between groups. We found no evidence that immobilization after arthroscopic rotator cuff repair was superior to early-motion rehabilitation in terms of tendon healing or clinical outcome. Patients in the early-motion group may recover ROM more rapidly. Level II; systematic review of levels I and II studies.

Upper trunk obstetric brachial plexus injury can cause profound shoulder and elbow dysfunction. Although neuroma excision with interpositional sural nerve grafting is the current gold standard, distal nerve transfers have a number of potential advantages. The goal of this study was to compare the clinical outcomes and health care costs between nerve grafting and distal nerve transfers in children with upper trunk obstetric brachial plexus injury. In this prospective cohort study, children who underwent triple nerve transfers were followed with the Active Movement Scale for 2 years. Their outcomes were compared to those of children who underwent nerve graft reconstruction. To assess health care use, a cost analysis was also performed. Twelve patients who underwent nerve grafting were compared to 14 patients who underwent triple nerve transfers. Both groups had similar baseline characteristics and showed improved shoulder and elbow function following surgery. However, the nerve transfer group displayed significantly greater improvement in shoulder external rotation and forearm supination 2 years after surgery (p < 0.05). The operative time and length of hospital stay were significantly lower (p < 0.05), and the overall cost was approximately 50 percent less in the nerve transfer group. Triple nerve transfer for upper trunk obstetric brachial plexus injury is a feasible option, with better functional shoulder external rotation and forearm supination, faster recovery, and lower cost compared with traditional nerve graft reconstruction.

Abstract: SAPS simulation with GITM/UCLA-RCM coupled model Author: Yang Lu, Yue Deng, Jiapeng Guo, Donghe Zhang, Chih-Ping Wang, Cheng Sheng Ion velocity in the Sub Aurora region observed by Satellites in storm time often shows a significant westward component. The high speed westward stream is distinguished with convection pattern. These kind of events are called Sub Aurora Polarization Stream (SAPS). In March 17th 2013 storm, DMSP F18 satellite observed several SAPS cases when crossing Sub Aurora region. In this study, Global Ionosphere Thermosphere Model (GITM) has been coupled to UCLA-RCM model to simulate the impact of SAPS during March 2013 event on the ionosphere/thermosphere. The particle precipitation and electric field from RCM has been used to drive GITM. The conductance calculated from GITM has feedback to RCM to make the coupling to be self-consistent. The comparison of GITM simulations with different SAPS specifications will be conducted. The neutral wind from simulation will be compared with GOCE satellite. The comparison between runs with SAPS and without SAPS will separate the effect of SAPS from others and illustrate the impact on the TIDS/TADS propagating to both poleward and equatorward directions.

Increasingly, hospitals and physicians are becoming acquainted with business intelligence strategies and tools to improve quality of care. In 2007, the University of California Los Angeles (UCLA) Department of Neurosurgery created a quality dashboard to help manage process measures and outcomes and ultimately to enhance clinical performance and patient care. At that time, the dashboard was in a platform that required data to be entered manually. It was then reviewed monthly to allow the department to make informed decisions. In 2009, the department leadership worked with the UCLA Medical Center to align mutual quality-improvement priorities. The content of the dashboard was redesigned to include 3 areas of priorities: quality and safety, patient satisfaction, and efficiency and use. Throughout time, the neurosurgery quality dashboard has been recognized for its clarity and its success in helping management direct improvement strategies and monitor impact. We describe the creation and design of the neurosurgery quality dashboard at UCLA, summarize the evolution of its assembly process, and illustrate how it can be used as a powerful tool of improvement and change. The potential challenges and future directions of this business intelligence tool are also discussed.

Rupture of any two or more parts of the superior shoulder suspensory complex (SSSC) including the distal clavicle, acromion, coracoid process, glenoid cavity of the scapula, acromioclavicular ligament, and coracoclavicular ligament is associated with shoulder girdle instability and is an indication for surgery. Here we report a case of acromioclavicular joint dislocation associated with coracoid process fracture. A 48-year-old man sustained a hard blow to the left shoulder from a fall, and simple radiography detected a coracoid process fracture and acromioclavicular joint dislocation. The injury consisted of a rupture of two parts of the SSSC. For the coracoid process fracture, osteosynthesis was performed using hollow cancellous bone screws. For the acromioclavicular joint dislocation, hook plate fixation and the modified Neviaser's procedure were performed. The bone healed well 5 months after surgery, at which time the screws were removed. At 18 months after initial surgery, the coracoid process fracture had healed with a 10% rate of dislocation on radiography, and the patient currently has no problem performing daily activities, no range of motion limitations, and a Japanese Orthopaedic Association scale score of 93.

Theoretical Study of α-V2O5 -Based Double-Wall Nanotubes.

2015-10-05

First-principles calculations of the atomic and electronic structure of double-wall nanotubes (DWNTs) of α-V2 O5 are performed. Relaxation of the DWNT structure leads to the formation of two types of local regions: 1) bulk-type regions and 2) puckering regions. Calculated total density of states (DOS) of DWNTs considerably differ from that of single-wall nanotubes and the single layer, as well as from the DOS of the bulk and double layer. Small shoulders that appear on edges of valence and conduction bands result in a considerable decrease in the band gaps of the DWNTs (up to 1 eV relative to the single-layer gaps). The main reason for this effect is the shift of the inner- and outer-wall DOS in opposite directions on the energetic scale. The electron density corresponding to shoulders at the conduction-band edges is localized on vanadium atoms of the bulk-type regions, whereas the electron density corresponding to shoulders at the valence-band edges belongs to oxygen atoms of both regions. © 2015 WILEY-VCH Verlag GmbH & Co.

Patient-reported outcome measures (PROMs) are valuable tools for quantifying outcomes of orthopedic surgery. However, when baseline scores are not obtained, there is considerable controversy about whether PROMs can be administered retrospectively for patients to recall their preoperative state. We investigated the accuracy of patient recall after total shoulder arthroplasty (TSA) using the American Shoulder and Elbow Surgeons (ASES) assessment score. Recalled ASES scores were collected postoperatively at 6 weeks, 3 months, 6 months, and 12 months from 169 patients who previously completed baseline scores before TSA. The ASES total score was divided into its two subcomponents: functional ability and visual analog scale (VAS) for pain. We compared preoperative and recalled scores for each subcomponent and the total ASES score. Recalled ASES function scores were comparable to corresponding preoperative scores across all time points (analysis of variance, P = .21), but recalled VAS pain was significantly higher at all time points beyond 6 weeks after surgery (P = .0001 at 3 months; P = .005 at 6 months; and P = .001 at 12 months). As a result, the ASES total score was only comparable at 6 weeks after surgery (P = .39) and differed at all time points thereafter. Patients are able to recall preoperative function with considerable accuracy for up to 12 months after TSA. However, beyond 6 weeks postoperatively, patients recall having worse pain than they originally reported, and recalled ASES total scores are unreliable as a result.

Massage therapy is one of the most commonly used complementary therapies for patients with Parkinson's disease (PD). The aim of this preliminary study was to evaluate the effects of traditional Japanese massage therapy on various symptoms of patients with PD. The study design was a case series study. The study was conducted at the Center for Integrative Medicine, Tsukuba University of Technology, Japan. The subjects were 10 patients with idiopathic PD (mean age, 69.6±7.7 years; range, 55-85 years) who presented for consultation with a neurologist between February and April 2009 and who desired massage therapy in conjunction with standard pharmaceutical treatment. The intervention comprised a 30-minute session of traditional Japanese massage in conjunction with standard conventional medication. The outcome measures were as follows: Gait speed in the 20-m walk test (10-m walk and return) for gait disturbance, angular range of shoulder joint motion for frozen shoulder, and a visual analogue scale (VAS) for assessing the severity of each of various symptoms (hypophonia, shoulder stiffness, muscle pain, heaviness or lassitude of a body part, and fatigue), as determined before and after the massage session. (1) Patients with gait disturbance showed improved gait speed, (2) those with frozen shoulder showed improved range of motion of the shoulder joint, and (3) VAS scores for assessing the severity of other subjective symptoms were improved. These results suggest that traditional Japanese massage therapy used in combination with medication is effective for alleviating various symptoms in patients with PD and may contribute to enhancing their health-related quality of life. Larger studies with a control group are required to verify these findings.

To compare the effects of platelet-rich plasma injection with those of dry needling on shoulder pain and function in patients with rotator cuff disease. A single-centre, prospective, randomized, double-blinded, controlled study. University rehabilitation hospital. Thirty-nine patients with a supraspinatus tendon lesion (tendinosis or a partial tear less than 1.0 cm, but not a complete tear) who met the inclusion criteria recruited between June 2010 and February 2011. Two dry needling procedures in the control group and two platelet-rich plasma injections in the experimental group were applied to the affected shoulder at four-week intervals using ultrasound guidance. The Shoulder Pain and Disability Index, passive range of motion of the shoulder, a physician global rating scale at the six-month follow-up, adverse effects monitoring and an ultrasound measurement were used as outcome measures. The clinical effect of the platelet-rich plasma injection was superior to the dry needling from six weeks to six months after initial injection (P < 0.05). At six months the mean Shoulder Pain and Disability Index was 17.7 ± 3.7 in the platelet-rich plasma group versus 29.5 ± 3.8 in the dry needling group (P < 0.05). No severe adverse effects were observed in either group. Autologous platelet-rich plasma injections lead to a progressive reduction in the pain and disability when compared to dry needling. This benefit is certainly still present at six months after treatment. These findings suggest that treatment with platelet-rich plasma injections is safe and useful for rotator cuff disease.

Rotator cuff tears are one of the most common causes of shoulder malfunction and pain, which lead to a significant reduction in the quality of life. This present study investigated the effects of subacromial platelet-rich plasma injections [i.e. autologous conditioned plasma (ACP) injections] as compared to standard subacromial cortisone injection therapy in 50 patients with partial rotator cuff tears. Before injection, and 6 weeks, 12 weeks and 6 months thereafter, the patients were assessed by the Constant-Murley score (CMS), the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), the simple shoulder test (SST) and a pain visual analogue scale (VAS). An MRI was also performed before and 6 months after injection. Both patient groups had statistically significant better shoulder score outcomes over time. ASES, SST and CMS outcomes after 12 versus 6 weeks were better in the ACP group as compared to the cortisone group. VAS, ASES and CMS outcomes after 12 weeks versus baseline in the ACP group were better as compared to the cortisone group. There was a statistically significant difference between ACP group and cortisone group 12 weeks after injection regarding VAS, ASES, SST and CMS in favour of the ACP group. The MRI showed an improvement in grade of tendinopathy in both groups, however, without statistically significant differences between the two groups. Compared with cortisone injections, ACP injections show earlier benefit as compared to cortisone injections although a statistically significant difference after 6 months could not be found. Therefore, subacromial ACP injections are a good alternative to subacromial cortisone injections, especially in patients with contraindication to cortisone. Therapeutic study, Level III.

Introduction Chronic shoulder pain is a very complex syndrome, and the mechanisms involved in its perpetuation remain unclear. Psychological factors appear to play a role in the perpetuation of symptoms in people with shoulder chronicity. The purpose of this systematic review is to examine the role of psychological factors in the perpetuation of symptoms (pain intensity and disability) in people with chronic shoulder pain. Methods and analysis A systematic search was performed on PubMed, AMED, CINAHL, PubPsych and EMBASE from inception to July 2017. Longitudinal studies with quantitative designs analysing the role of psychological factors on pain intensity, disability or both were included. The methodological quality of the included studies was evaluated with an adapted version of the Newcastle Ottawa Scale. The level of evidence per outcome was examined using the Grading of Recommendations Assessment, Development and Evaluation approach. Results A total of 27 articles were included with a sample of 11 176 people with chronic shoulder pain. The risk of bias ranges from 7/21 to 13/21 across the studies. The quality of the evidence was very low. High levels of self-efficacy, resilience and expectations of recovery were significantly associated with low levels of pain intensity and disability. Inversely, high levels of emotional distress, depressive symptoms, anxiety, preoperative concerns, fear-avoidance beliefs, somatisation and pain catastrophising were significantly associated with high levels of pain intensity and disability. Discussion Our results suggest that psychological factors may influence the perpetuation of pain intensity and disability, with very low evidence. A meta-analysis was not carried out due to the heterogeneity of the included studies so results should be interpreted with caution. PROSPERO trial registration number CRD42016036366. PMID:29654040

This study presents the preliminary results of a new arthroscopic technique consisting of the association of 2 procedures, capsulolabral repair and subscapularis augmentation tenodesis, in the treatment of traumatic anterior shoulder instability with both glenoid bone loss and a Hill-Sachs lesion. Eighty-nine patients engaged in sports were enrolled in this retrospective case-series study with 2 to 5 years' follow-up. All patients underwent a computed tomography scan to assess the percentage of glenoid bone loss by the Pico method. A prior stabilization procedure had failed in 20 patients, who were then segregated into a different group. Visual analog scale (VAS), Rowe, and American Shoulder and Elbow Surgeons (ASES) scores were used to assess the results. Only 3 of 89 patients had a post-traumatic redislocation. The mean length of follow-up was 31.5 months (range, 25-60 months). The VAS, Rowe, and ASES scores showed significant improvements: The VAS score decreased from a mean of 3.1 to 0.5 (P = .0157), the Rowe score increased from 58.9 to 94.1 (P = .0215), and the ASES score increased from 68.5 to 95.5 (P = .0197). The mean deficit of external rotation was 6° with the arm at the side of the trunk, and the mean deficit was 3° with the arm in 90° of abduction. The described procedure is a reproducible and effective technique used to restore joint stability in patients engaged in sports who have incurred anterior recurrent shoulder dislocation associated with glenoid bone loss (<25%) and a Hill-Sachs lesion.

Postoperative pain control is a significant concern after total shoulder arthroplasty. Injectable periarticular liposomal bupivacaine, which has been found to decrease opioid use after orthopedic procedures, has been proposed as a viable alternative to regional anesthesia. This study compared the efficacy of liposomal bupivacaine vs interscalene block among patients undergoing total shoulder arthroplasty. A retrospective review was conducted of 79 patients who underwent anatomic total shoulder arthroplasty performed by a single surgeon between January 2013 and April 2015. Patient demographics, in-hospital Numeric Pain Rating Scale (NPRS) score obtained at 12-hour intervals, length of stay, and total in-hospital morphine equivalents in both the bupivacaine (n=25) and block (n=44) groups were recorded. Differences in length of stay, morphine equivalents, and age were assessed with Wilcoxon tests. Sex differences were assessed with the chi-square test. Repeated measures analysis with least square means was used to assess longitudinal changes in NPRS scores. No significant differences were found between groups for sex (P=.89), age (P=.81), American Society of Anesthesiologists classification (P=.50), preoperative opioid use (P=.41), length of stay (P=.32), or morphine equivalents (P=.71). The average NPRS score in the first 12 hours was 3.01 for the bupivacaine group and 4.41 for the interscalene block group (P=.25). By 48 hours postoperatively, average NPRS scores were similar (P=.93) for the 2 groups, 4.90 for the bupivacaine group and 4.19 for the interscalene block group. The findings for this cohort of patients undergoing anatomic total shoulder arthroplasty showed no significant difference for pain scores, postoperative narcotic use, or length of stay with injectable liposomal bupivacaine vs interscalene block.

The effects of balneotherapy on chronic shoulder pain were studied. In this single-blind, randomized, follow-up study involving 46 patients with chronic shoulder pain, one group of patients received physiotherapy--exercise and transcutaneous electrical nerve stimulation--and the other group received balneotherapy in addition to physiotherapy for 4 weeks on 15 occasions. The following parameters were recorded before treatment (at week 0) and after treatment (at weeks 4, 7, and 13): Shoulder Pain and Disability Index (SPADI), the Short Form (36) Health Survey (SF-36) and EuroQuol-5D (EQ-5D) quality of life questionnaires, pain at rest and on movement on the visual analog scale (VAS), and active and passive range of motion. The SPADI pain, function, and total scores and the VAS scores at rest and on movement significantly improved in both groups after treatments. A greater improvement was observed in the balneotherapy group compared to the control group; regarding some parameters (VAS score on movement and SPADI function score at visit 2; VAS score at rest at visits 3 and 4), the difference between the groups was significant. The improvement of SF-36 and EQ-5D quality of life scores and the active range of motion was more pronounced in the balneotherapy group, the difference between the groups was not significant, except for EQ-5D at visit 2. Improvement of passive range of motion was not significant. Balneotherapy may have a beneficial effect on the clinical parameters and quality of life of patients with chronic shoulder pain. The number of patients should be increased.

To analyze the validity of measurements of medial rotation (MR) of the shoulder, using vertebral levels, according to the variation in the position of the humeral diaphysis, and to test the bi-goniometer as a new measuring instrument. 140 shoulders (70 patients) were prospectively evaluated in cases presenting unilateral shoulder MR limitation. The vertebral level was evaluated by means of a visual scale and was correlated with the angle obtained according to the position of the humeral diaphysis, using the bi-goniometer developed with the Department of Mechanical Engineering of Mackenzie University. The maximum vertebral level reached through MR on the unaffected side ranged from T3 to T12, and on the affected side, from T6 to the trochanter. Repositioning of the affected limb in MR according to the angular values on the normal side showed that 57.13% of the patients reached lower levels, between the sacrum, gluteus and trochanter. From analysis on the maximum vertebral level attained and the variation between the affected angle x (frontal plane: abduction and MR of the shoulder) and the unaffected angle x in MR, we observed that the greater the angle of the diaphyseal axis was, the lower the variation in the vertebral level attained was. From evaluating the linear correlation between the variables of difference in maximum vertebral level reached and variation in the affected angle y (extension and abduction of the shoulder) and the unaffected angle y in MR, we observed that there was no well-established linear relationship between these variables. Measurement of MR using vertebral levels does not correspond to the real values, since it varies according to the positioning of the humeral diaphysis.

Conclusion: Measurement of MR using vertebral levels does not correspond to the real values, since it varies according to the positioning of the humeral diaphysis. PMID:27047845

Body mass index (BMI) has recently been identified as a predictor of outcomes following reconstructive surgery of shoulder palsies. In this study, we sought to determine if the same holds true for the reconstruction of elbow flexion. Forty patients who had undergone partial ulnar-to-biceps nerve transfer (Oberlin's procedure) for shoulder palsy were assessed and compared against 18 previously reported patients who had undergone reconstruction for elbow palsies. The British Medical Research Council (BMRC) scale and an index dividing shoulder abduction strength in the affected arm by healthy arm were recorded. All patients had undergone surgery within 12 months of injury and had ≥ 12 months of follow-up. M4 or M3 biceps strength was obtained in 90 % of patients. Final strength on the affected side averaged 5.8 kg, versus 20.2 kg on the normal side, for a mean recovery index score of 0.30. In this sample of 40 patients, BMI did not predict percentage strength or BMRC grade recovery. Neither did age, number of roots involved, the affected side, nor time to surgery. Comparing patients with elbow versus shoulder reconstruction, there were no differences, except that patients undergoing Oberlin's procedure had a statistically longer duration of time between injury and surgical repair (7.4 vs 5.1 months, p < 0.006). Our data suggest that proximal muscle re-innervation is functionally more dependent upon BMI than distal re-innervation, likely because proximal muscles must support the weight of the entire extremity, while more distal muscles do not. BMI should be taken into consideration when planning surgery.

Chronic pain and disability of the arm, shoulder, and hand severely affect labor market participation. Ergonomic training and education is the default strategy to reduce physical exposure and thereby prevent aggravation of pain. An alternative strategy could be to increase physical capacity of the worker by physical conditioning. To investigate the effect of 2 contrasting interventions, conventional ergonomic training (usual care) versus resistance training, on pain and disability in individuals with upper limb chronic pain exposed to highly repetitive and forceful manual work. Examiner-blinded, parallel-group randomized controlled trial with allocation concealment. Slaughterhouses located in Denmark, Europe. Sixty-six adults with chronic pain in the shoulder, elbow/forearm, or hand/wrist and work disability were randomly allocated to 10 weeks of specific resistance training for the shoulder, arm, and hand muscles for 3 x 10 minutes per week, or ergonomic training and education (usual care control group). Pain intensity (average of shoulder, arm, and hand, scale 0 - 10) was the primary outcome, and disability (Work module of DASH questionnaire) as well as isometric shoulder and wrist muscle strength were secondary outcomes. Pain intensity, disability, and muscle strength improved more following resistance training than usual care (P < 0.001, P = 0.05, P <0.0001, respectively [corrected]). Pain intensity decreased by 1.5 points (95% confidence interval -2.0 to -0.9) following resistance training compared with usual care, corresponding to an effect size of 0.91 (Cohen's d). Blinding of participants is not possible in behavioral interventions. However, at baseline outcome expectations of the 2 interventions were similar. Resistance training at the workplace results in clinical relevant improvements in pain, disability, and muscle strength in adults with upper limb chronic pain exposed to highly repetitive and forceful manual work.

Traditionally, fewer postoperative sport restrictions are imposed on hemiarthroplasty (HHA) patients on than reverse total shoulder arthroplasty (RTSA) patients. However, functional outcomes have been shown to be superior in RTSA. No direct comparison of RTSA vs HHA has been done on rates of return to sports in patients with glenohumeral arthritis and rotator cuff dysfunction, proximal humeral fractures, or rheumatoid arthritis. This is a retrospective review of consecutive RTSA and HHA patients collected from our institution's shoulder arthroplasty registry. All patients playing sports preoperatively with minimum 1-year follow-up were included. Final follow-up included an additional patient-reported questionnaire with questions regarding physical fitness and sport activities. The study included 102 RTSA and 71 HHA patients. Average age at surgery was 72.3 years for RTSA compared with 65.6 years for HHA (P < .001). Patients undergoing RTSA had improved visual analog scale scores compared with HHA (-5.6 vs -4.2, P = .007), returned to sports after RTSA at a significantly higher rate (85.9% vs 66.7%, P = .02), and were more likely to be satisfied with their ability to play sports (P = .013). HHA patients were also more likely to have postoperative complaints than RTSA patients (63% vs 29%, P < .0001). No sports-related complications occurred. Female sex, age <70 years, surgery on the dominant extremity, and a preoperative diagnosis of arthritis with rotator cuff dysfunction predicted a higher likelihood of return to sports for patients undergoing RTSA compared with HHA. Despite traditional sport restrictions placed on RTSA, patients undergoing RTSA can return to sports at rates higher than those undergoing HHA, with fewer postoperative complaints.

The primary purpose of this study was to examine relations between trauma exposure, post-resettlement stressors, perceived discrimination, and mental health symptoms in Somali adolescent refugees resettled in the U.S. Participants were English-speaking Somali adolescent refugees between the ages of 11 and 20 (N = 135) who had resettled in the U.S. Participants were administered an interview battery comprising self-report instruments that included the UCLA Posttraumatic Stress Disorder (PTSD) Index, the War Trauma Screening Scale, the Every Day Discrimination scale, the Adolescent Post-War Adversities Scale, and the Acculturative Hassles Inventory. Results indicated that cumulative trauma was related to PTSD and depression symptoms. Further, post-resettlement stressors, acculturative stressors, and perceived discrimination were also associated with greater PTSD symptoms after accounting for trauma, demographic, and immigration variables. Number of years since resettlement in the US and perceived discrimination were significantly related to depressive symptoms, after accounting for trauma, demographic, and immigration variables. Further research elucidating the relations between post-resettlement stressors, discrimination, and mental health of refugee adolescents may inform intervention development.

Ice hockey body checks involving direct shoulder-to-head contact frequently result in head injury. In the current study, we examined the effect of shoulder pad style on the likelihood of head injury from a shoulder-to-head check. Shoulder-to-head body checks were simulated by swinging a modified Hybrid-III anthropomorphic test device (ATD) with and without shoulder pads into a stationary Hybrid-III ATD at 21 km/h. Tests were conducted with three different styles of shoulder pads (traditional, integrated and tethered) and without shoulder pads for the purpose of control. Head response kinematics for the stationary ATD were measured. Compared to the case of no shoulder pads, the three different pad styles significantly (p < 0.05) reduced peak resultant linear head accelerations of the stationary ATD by 35-56%. The integrated shoulder pads reduced linear head accelerations by an additional 18-21% beyond the other two styles of shoulder pads. The data presented here suggest that shoulder pads can be designed to help protect the head of the struck player in a shoulder-to-head check.

To investigate African unaccompanied refugee minors (URMs) living in Austria for posttraumatic stress disorder (PTSD) prevalence and related symptoms, comorbidity, demographics and coping strategies. "UCLA PTSD Index and inventories" and "Scales for Children Afflicted by War and Persecution (SCWP)" were used to assess 41 African URMs. The study revealed lower PTSD rates than measured among URMs in previous studies. Girls were more likely to develop PTSD. PTSD was significantly correlated with single war-related traumatic events. The depression score for the sample was above the clinical cut-off value. Trauma-specific psychopathology was less severe than reported in other studies. These findings could be explained by concepts of resilience. Other implications, such as response bias, are discussed.

Use of animals for therapeutic purposes, animal assisted therapy or AAT is a method for improving quality of life for long-term inpatients. The object of this paper was to evaluate dog companionship as a form of AAT and its effects on perception of loneliness in geriatric nursing home residents. The participants were involved in a six-month program of dog companionship three times weekly for 90 minutes. There were 21 residents included in the program, with a mean age of 80 years. Loneliness was measured by the short version of the UCLA Scale of loneliness. Comparison of test results before and after participation in the program showed that dog companionship reduces the perception of loneliness.

We present 3D global fluid simulations of the UCLA upgraded Large Plasma Device (LAPD). This device confines an 18-m-long, cylindrically symmetric plasma with a uniform magnetic field. The plasma in the simulations is generated by density and temperature sources inside the computational domain, and sheath boundary conditions are applied at the ends of the plasma column. In 3D simulations of the entire plasma, we observe strong, rotating intermittent density and temperature fluctuations driven by resistive driftwave turbulence with finite parallel wavenumbers. Analogous simulations carried out in the 2D limit (that is, assuming that the motions are purely interchange-like) display much weaker mode activity driven a Kelvin-Helmholtz instability. The properties and scaling of the turbulence and transport will be discussed.
