Aim. This study investigates consequences of chronic neck pain on muscle function and the rehabilitating effects of contrasting interventions. Methods. Women with trapezius myalgia (MYA, n = 42) and healthy controls (CON, n = 20) participated in a case-control study. Subsequently MYA were randomized to 10 weeks of specific strength training (SST, n = 18), general fitness training (GFT, n = 16), or a reference group without physical training (REF, n = 8). Participants performed tests of 100 consecutive cycles of 2 s isometric maximal voluntary contractions (MVC) of shoulder elevation followed by 2 s relaxation at baseline and 10-week follow-up. Results. In the case-control study, peak force, rate of force development, and rate of force relaxation as well as EMG amplitude were lower in MYA than CON throughout all 100 MVC. Muscle fiber capillarization was not significantly different between MYA and CON. In the intervention study, SST improved all force parameters significantly more than the two other groups, to levels comparable to that of CON. This was seen along with muscle fiber hypertrophy and increased capillarization. Conclusion. Women with trapezius myalgia have lower strength capacity during repetitive MVC of the trapezius muscle than healthy controls. High-intensity strength training effectively improves strength capacity during repetitive MVC of the painful trapezius muscle. PMID:24707475

Improving cancer pain management in Malaysia.

Lim, Richard

2008-01-01

Within Malaysia's otherwise highly accessible public healthcare system, palliative medicine is still an underdeveloped discipline. Government surveys have shown that opioid consumption in Malaysia is dramatically lower than the global average, indicating a failure to meet the need for adequate pain control in terminally ill patients. Indeed, based on daily defined doses, only 24% of patients suffering from cancer pain receive regular opioid analgesia. The main barriers to effective pain control in Malaysia relate to physicians' and patients' attitudes towards the use of opioids. In one survey of physicians, 46% felt they lacked knowledge to manage patients with severe cancer pain, and 64% feared effects such as respiratory depression. Fear of addiction is common amongst patients, as is confusion regarding the legality of opioids. Additional barriers include the fact that no training in palliative care is given to medical students, and that smaller clinics often lack facilities to prepare and stock cheap oral morphine. A number of initiatives aim to improve the situation, including the establishment of palliative care departments in hospitals and implementation of post-graduate training programmes. Campaigns to raise public awareness are expected to increase patient demand for adequate cancer pain relief as part of good care. Copyright 2008 S. Karger AG, Basel.

The purpose of this study was to assess the extent to which patients undergoing flexible bronchoscopy (FOB) experience pain and to identify patient factors and process of care factors that are associated with pain. We conducted a prospective cohort study on 481 patients undergoing FOB. Overall control of pain during FOB was the primary outcome. The mean age of the patients was 48 yr, 50% were male, and 32% required supplemental oxygen prior to FOB. Pain control was excellent in 36% of patients, but 10% considered it to be fair or poor. Patient factors associated with excellent pain control were excellent health (versus poor health, OR = 6.25 [95% CI, 2.28-16.67]), more education (college education versus high school education, OR = 1.72 [95% CI, 1.05-2.86]), and not having asthma (OR = 2.86 [95% CI, 1.09-7.14]). Process of care factors associated with excellent pain control were not being bothered by scope insertion (versus bothered, OR = 3.65 [95% CI, 1.99-6.98]), no memory of FOB (versus some memory, OR = 2.33 [95% CI, 1.24-4.44]), and higher ratings of information about the procedure (per 1-point increase on a 12-point scale, OR = 1.57 [95% CI, 1.41-1.78]). This is the first large-scale, prospective study to evaluate patient and process of care factors that influence pain control during FOB. It demonstrated that there are patient characteristics and process of care factors that need to be considered when evaluating pain during bronchoscopy. Improved preparation of patients with lower education, inferior health status, and asthma may lead to decreased pain during FOB. Bronchoscopists may be able to reduce pain during FOB by identifying methods to decrease pain on scope insertion, by improving the information provided to patients, and by achieving greater levels of amnesia during FOB.

To evaluate the effect of swimming on pain, functional capacity, aerobic capacity, and quality of life in patients with fibromyalgia (FM). Randomized controlled trial. Rheumatology outpatient clinics of a university hospital. Women with FM (N=75; age range, 18-60y) randomly assigned to a swimming group (SG) (n=39) or a walking group (WG) (n=36). The SG performed 50 minutes of swimming 3 times a week for 12 weeks, with a heart rate at 11 beats under the anaerobic threshold. The WG performed walking with a heart rate at the anaerobic threshold, with the same duration and frequency as the SG. Participants were evaluated before the exercise protocols (t0), at 6 weeks (t6), and at 12 weeks (t12) after the onset of the protocols. The primary outcome measure was the visual analog scale for pain. The secondary measurements were the Fibromyalgia Impact Questionnaire and the Medical Outcomes Study 36-Item Short-Form Health Survey for quality of life; a spiroergometric test for cardiorespiratory variables; and the timed Up & Go test for functional performance. Patients in both groups experienced improvement in pain after the 12-week program, with no difference between groups (P=.658). The same results were found regarding functional capacity and quality of life. Moreover, no statistical difference between groups was found regarding aerobic capacity over time. Swimming, like walking, is an effective method for reducing pain and improving both functional capacity and quality of life in patients with FM.

Chronic whiplash is a debilitating condition characterized by increased sensitivity to painful stimuli, maladaptive illness beliefs, inappropriate attitudes, and movement dysfunctions. Previous work in people with chronic low back pain and chronic fatigue syndrome indicates that pain neurophysiology education is able to improve illness beliefs and attitudes as well as movement performance. This single-case study (A-B-C design) with six patients with chronic whiplash associated disorders (WAD) was aimed at examining whether education about the neurophysiology of pain is accompanied by changes in symptoms, daily functioning, pain beliefs, and behavior. Periods A and C represented assessment periods, while period B consisted of the intervention (pain neurophysiology education). Results showed a significant decrease in kinesiophobia (Tampa Scale for Kinesiophobia), the passive coping strategy of resting (Pain Coping Inventory), self-rated disability (Neck Disability Index), and photophobia (WAD Symptom List). At the same time, significantly increased pain pressure thresholds and improved pain-free movement performance (visual analog scale on Neck Extension Test and Brachial Plexus Provocation Test) were established. Although the current results need to be verified in a randomized, controlled trial, they suggest that education about the physiology of pain is able to increase pain thresholds and improve pain behavior and pain-free movement performance in patients with chronic WAD.

The objective of this study was to examine alteration in head repositioning accuracy (HRA), range of motion, and pain intensity in patients with chronic cervical pain syndrome without a history of cervical trauma. The study was a prospective, randomized, controlled trial. Forty-one patients with chronic cervical pain were randomly assigned to either a control group or a chiropractic treatment group. All patients were clinically examined, given general information on cervical pain, and provided with training instructions based on the clinical evaluation. The treatment included sessions with high-velocity and low-amplitude manipulation, proprioceptive neuromuscular facilitation, ischemic compression of myofascial trigger points, and spinal rehabilitation exercises aiming to normalize cervical range of motion (CROM) and HRA. Subjective pain intensity, cervical kinesthetic sensibility, and CROM were recorded before and after the study period. There was no difference between the treatment patients and the control subjects at the beginning with regard to age, sex, subjective pain intensity, range of motion, and HRA. At the 5-week follow-up, the treatment patients showed significant reductions in pain and improvement of all HRA aspects measured whereas the control subjects did not show any reduction in pain and improvement in only one HRA aspect. No significant difference was detected in CROM. The results of this study suggest that chiropractic care can be effective in influencing the complex process of proprioceptive sensibility and pain of cervical origin. Short, specific chiropractic treatment programs with proper patient information may alter the course of chronic cervical pain.

To investigate the effect of combining pain education, specific exercises and graded physical activity training (exercise) compared with pain education alone (control) on physical health-related quality of life (HR-QoL) in chronic neck pain patients. A multicentre randomised controlled trial of 200 neck pain patients receiving pain education. The exercise group received additional exercises for neck/shoulder, balance and oculomotor function, plus graded physical activity training. Patient-reported outcome measures (Short Form-36 Physical and Mental component summary scores, EuroQol-5D, Beck Depression Inventory-II, Neck Disability Index, Pain Bothersomeness, Patient-Specific Functioning Scale, Tampa Scale of Kinesiophobia, Global Perceived Effect) and clinical tests (Aastrand Physical Fitness, cervical Range of Motion, Pressure Pain Threshold at infraspinatus, tibialis anterior and cervical spine, Cranio-cervical Flexion, Cervical Extension muscle function, and oculomotion) were recorded at baseline and after 4 months. The exercise group showed statistically significant improvement in physical HR-QoL, mental HR-QoL, depression, cervical pressure pain threshold, cervical extension movement, muscle function, and oculomotion. Per protocol analyses confirmed these results with additional significant improvements in the exercise group compared with controls. This multimodal intervention may be an effective intervention for chronic neck pain patients.

Cancer pain is a distressing and complex experience. It is feasible that the systematic collection and feedback of patient-reported outcome measurements (PROMs) relating to pain could enhance cancer pain management. We aimed to conduct a systematic review of interventions in which patient-reported pain data were collected and fed back to patients and/or professionals in order to improve cancer pain control. MEDLINE, EMBASE and CINAHL databases were searched for randomised and non-randomised controlled trials in which patient-reported data were collected and fed back with the intention of improving pain management by adult patients or professionals. We conducted a narrative synthesis. We also conducted a meta-analysis of studies reporting pain intensity. 29 reports from 22 trials of 20 interventions were included. PROM measures were used to alert physicians to poorly controlled pain, to target pain education and to link treatment to management algorithms. Few interventions were underpinned by explicit behavioural theories. Interventions were inconsistently applied or infrequently led to changes in treatment. Narrative synthesis suggested that feedback of PROM data tended to increase discussions between patients and professionals about pain and/or symptoms overall. Meta-analysis of 12 studies showed a reduction in average pain intensity in intervention group participants compared with controls (mean difference=-0.59 (95% CI -0.87 to -0.30)). Interventions that assess and feedback cancer pain data to patients and/or professionals have so far led to modest reductions in cancer pain intensity. Suggestions are given to inform and enhance future PROM feedback interventions. Published by the BMJ Publishing Group Limited.

Bailey, Lucas; Sun, Jing; Courtney, Mark; Murphy, Paul

2015-05-01

To evaluate paediatric post-tonsillectomy pain management using oxycodone when a specific analgesia information sheet is included with standard postoperative information. Oxycodone information sheets were randomly allocated to half the study children's post-tonsillectomy information pack. The trial was double-blinded to the surgeon, anaesthetist, nursing and administrative staff. Parents and children completed the pain assessment on day 3, 5 and 7. On day 10 the parents completed a questionnaire. A postoperative analgesia information sheet provides for higher satisfaction and knowledge for parents using oxycodone (p<0.001) and children have improved postoperative pain control, most significantly at day 5 (p<0.05). Parent assessment of the child's analgesia was superior with the oxycodone information sheet, most significantly at day 3 and 7 post operatively (p<0.05). There is also a positive correlation between the parents' observed pain score and children's self reported pain score, with a low correlation efficient level observed (p<0.001). Information sheets are useful in education and use of postoperative analgesia. The primary objective to explore the efficacy of the information sheet has proved to be successful in this setting. Given risks of opioid analgesia, it is recommended that postoperative information sheets be given to all parents, to provide for improved analgesia control and safe management of children in the postoperative period.

To evaluate whether psychotherapy with somatosensory stimulation is effective for the treatment of pain and quality of life in patients with endometriosis-related pain. Patients with a history of endometriosis and chronic pelvic pain were randomized to either psychotherapy with somatosensory stimulation (ie, different techniques of acupuncture point stimulation) or wait-list control for 3 months, after which all patients were treated. The primary outcome was brain connectivity assessed by functional magnetic resonance imaging. Prespecified secondary outcomes included pain on 11-point numeric rating scales (maximal and average global pain, pelvic pain, dyschezia, and dyspareunia) and physical and mental quality of life. A sample size of 30 per group was planned to compare outcomes in the treatment group and the wait-list control group. From March 2010 through March 2012, 67 women (mean age 35.6 years) were randomly allocated to intervention (n=35) or wait-list control (n=32). In comparison with wait-list controls, treated patients showed improvements after 3 months in maximal global pain (mean group difference -2.1, 95% confidence interval [CI] -3.4 to -0.8; P=.002), average global pain (-2.5, 95% CI -3.5 to -1.4; P<.001), pelvic pain (-1.4, 95% CI -2.7 to -0.1; P=.036), dyschezia (-3.5, 95% CI -5.8 to -1.3; P=.003), physical quality of life (3.8, 95% CI 0.5-7.1, P=.026), and mental quality of life (5.9, 95% CI 0.6-11.3; P=.031); dyspareunia improved nonsignificantly (-1.8, 95% CI -4.4 to 0.7; P=.150). Improvements in the intervention group remained stable at 6 and 24 months, and control patients showed comparable symptom relief after delayed intervention. Psychotherapy with somatosensory stimulation reduced global pain, pelvic pain, and dyschezia and improved quality of life in patients with endometriosis. After 6 and 24 months, when all patients were treated, both groups showed stable improvements. ClinicalTrials.gov, https://clinicaltrials.gov, NCT01321840.

First trimester abortions especially cervical dilation and suction aspiration are associated with pain, despite various methods of pain control. Compare different methods of pain control during first trimester surgical abortion. We searched multiple electronic databases with the appropriate key words, as well as reference lists of articles, and contacted professionals to seek other trials. Randomized controlled trials comparing methods of pain control in first trimester surgical abortion at less than 14 weeks gestational age using electric or manual suction aspiration. Outcomes included intra- and postoperative pain, side effects, recovery measures and satisfaction. Two reviewers independently extracted data. Meta-analysis results are expressed as weighted mean difference (WMD) or Peto Odds ratio with 95% confidence interval (CI). We included forty studies with 5131 participants. Due to heterogeneity we divided studies into 7 groups:Local anesthesia: Data was insufficient to show a clear benefit of a paracervical block (PCB) compared to no PCB or a PCB with bacteriostatic saline. Pain scores during dilation and aspiration were improved with deep injection (WMD -1.64 95% CI -3.21 to -0.08; WMD 1.00 95% CI 1.09 to 0.91), and with adding a 4% intrauterine lidocaine infusion (WMD -2.0 95% CI -3.29 to -0.71, WMD -2.8 95% CI -3.95 to -1.65 with dilation and aspiration respectively).PCB with premedication: Ibuprofen and naproxen resulted in small reduction of intra- and post-operative pain.Analgesia: Diclofenac-sodium did not reduce pain.Conscious sedation: The addition of conscious intravenous sedation using diazepam and fentanyl to PCB decreased procedural pain.General anesthesia (GA): Conscious sedation increased intraoperative but decreased postoperative pain compared to GA (Peto OR 14.77 95% CI 4.91 to 44.38, and Peto OR 7.47 95% CI 2.2 to 25.36 for dilation and aspiration respectively, and WMD 1.00 95% CI 1.77 to 0.23 postoperatively).

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

This correlational study investigated the relationships between temperament, beliefs about pain control, and pain intensity ratings in a group of 103 women diagnosed with endometriosis. Temperament traits were assessed using the Formal Characteristics of Behaviour-Temperament Inventory. Beliefs about pain control were measured using the Polish version of the Beliefs about Pain Control Questionnaire. The Numerical Rating Scale (NRS-11) was used to measure pain intensity. There was a high negative correlation between the temperament trait of endurance and pain intensity ratings. Moderate negative correlations with pain intensity were found for internal beliefs about pain control. Hierarchical multiple regression analysis indicated that the endurance trait and internal beliefs about pain control accounted for 33 % of the variance in pain intensity ratings in women with endometriosis.

Patients with post-stroke spasticity (PSS) commonly experience pain in affected limbs, which may impact quality of life. To assess onabotulinumtoxinA for pain in patients with PSS from the BOTOX(®) Economic Spasticity Trial, a multicenter, randomized, double-blind, placebo-controlled trial. Patients with PSS (N = 273) were randomized to 22- to 34-week double-blind treatment with onabotulinumtoxinA + standard care (SC) or placebo injection + SC and were eligible to receive open-label onabotulinumtoxinA up to 52 weeks. Assessments included change from baseline on the 11-point pain numeric rating scale, proportion of patients with baseline pain ≥4 achieving ≥30% and ≥50% improvement in pain, and pain interference with work at Week 12, end of double-blind treatment, and Week 52. At baseline, most patients (74.3%) experienced pain and 47.4% had pain ≥4 (pain subgroup). Mean pain reduction from baseline at Week 12 was significantly greater with onabotulinumtoxinA + SC (-0.77, 95% CI -1.14 to -0.40) than placebo + SC (-0.13, 95% CI -0.51 to 0.24; P < 0.05). Higher proportions of patients in the pain subgroup achieved ≥30% and ≥50% reductions in pain at Week 12 with onabotulinumtoxinA + SC (53.7% and 37.0%, respectively) compared with placebo (28.8% and 18.6%, respectively; P < 0.05). Reductions in pain were sustained through Week 52. Compared with placebo + SC, onabotulinumtoxinA consistently reduced pain interference with work. This is the first randomized, placebo-controlled trial demonstrating statistically significant and clinically meaningful reductions in pain and pain interference with work with onabotulinumtoxinA in patients with PSS.

The institution of a postoperative Acute Pain Control Service is mandatory to improve the control of pain induced by surgical injury. Treatment of postoperative pain may be achieved using a combination of analgesic agents and techniques, reducing the incidence of side effects owing to the lower doses of the individual drugs. In 1997 we established an Acute Pain Service (APS) at the San Raffaele Hospital in Milan. The aim of this study was to assess the efficacy and safety of our APS both in terms of treatment protocols and organisational issues. In this prospective observational study we included 592 patients undergoing abdominal, gynecological, or orthopedic surgery with severe expected pain. According to general guidelines on pain treatment, the patients were assigned to different treatment protocols based on the kind of operation. All protocols were based on the multimodal therapy, with the association of nonsteroidal anti-inflammatory drugs (NSAIDS), opioids and regional anesthesia techniques. During the first 48 h of the postoperative period we recorded vital signs, level of pain and occurrence of any side effect. Our analgesic protocols proved to be effective and safe (low incidence of side effects) for every surgery. The incidence of postoperative nausea and vomiting was higher in patients receiving patient-controlled morphine than that with continuous epidural or nerve block. After lower abdominal surgery, pain at movement at 24 h was significantly lower in the epidural group than in the Patient Control Analgesia group. Nausea and vomiting, numbness and paresthesias at the lower limbs were higher in gynecological patients. A larger percentage of orthopedic patients in the epidural group reported numbness and paresthesias at the lower limbs in comparison with patients receiving continuous peripheral nerve block. In agreement with previous literature, this study confirmed that a multimodal approach to pain treatment provides an adequate control of

How parents respond to their child in pain is critically important to how both parent and child attempt to cope with pain. We examined the influence of parental catastrophic thinking about child pain on their prioritization for pain control. Using a vignette methodology, parents reported, in response to different pain scenarios, on their imagined motivation for 2 competing goals: to control their child's pain (ie, pain control) or to encourage their child's participation in daily activities (ie, activity engagement). The effects of parent gender, pain intensity, and duration on parental goal priority were also explored. Findings indicated that higher levels of parental catastrophic thoughts were associated with the parents prioritizing child pain control over activity engagement. This effect was significantly moderated by pain duration. Specifically, pain control was more of a priority for those high in catastrophic thinking when the pain was more acute. In contrast, parental catastrophic thoughts had no effect on the pain control strategy favored by parents in situations with longer-lasting pain. Furthermore, independently of parental catastrophic thoughts, heightened priority for pain control was observed in highly intense and chronic pain situations. Moreover, in highly intense pain, priority for pain control was stronger for mothers compared with fathers. Theoretical and clinical implications and directions for future research are discussed.

Previously, outpatient Yoga programs for patients with chronic low back pain (CLBP) lasting several months have been found to reduce pain, analgesic requirement and disability, and improve spinal mobility. This study evaluated changes in pain, anxiety, depression and spinal mobility for CLBP patients on short-term, residential Yoga and physical exercise programs, including comprehensive yoga lifestyle modifications. A seven day randomized control single blind active study in an residential Holistic Health Centre in Bangalore, India, assigned 80 patients (37 female, 43 male) with CLBP to yoga and physical exercise groups. The Yoga program consisted of specific asanas and pranayamas for back pain, meditation, yogic counselling, and lectures on yoga philosophy. The control group program included physical therapy exercises for back pain, and matching counselling and education sessions. Group×time interactions (p<0.05) and between group differences (p<0.05) were significant in all variables. Both groups' scores on the numerical rating scale for pain reduced significantly, 49% in Yoga (p<0.001, ES=1.62), 17.5% in controls (p=0.005, ES=0.67). State anxiety (STAI) reduced 20.4% (p<0.001, ES=0.72) and trait anxiety 16% (p<0.001, ES=1.09) in the yoga group. Depression (BDI) decreased in both groups, 47% in yoga (p<0.001, ES=0.96,) and 19.9% in controls (p<0.001, ES=0.59). Spinal mobility ('Sit and Reach' instrument) improved in both groups, 50%, in yoga (p<0.001, ES=2.99) and 34.6% in controls (p<0.001, ES=0.81). Seven days intensive residential Yoga program reduces pain, anxiety, and depression, and improves spinal mobility in patients with CLBP more effectively than physiotherapy exercises.

Evaluate laser acupuncture (LA) as an adjuvant therapy in pain management during percutaneous kidney biopsy procedure in children and adolescents. This prospective, double-blinded, randomized controlled trial enrolled patients aged 7 to 26 years admitted to a children's hospital for percutaneous kidney biopsy. Patients received LA to treatment points (acupuncture group) or sham points (control group) before the procedure. The laser delivered a dose of 42 J/cm over 10 acupoints. Patients and parents rated the pain during and after the biopsy, and change in pain scores were calculated for each patient. Anxiety, vital signs, sedation medication, and patient's biopsy experience were secondary outcomes. Sixty-nine treatments (33 in the acupuncture group and 36 in the control group) were eligible for analysis. Patients in the acupuncture group reported a significantly improved change in the pain score after the biopsy compared with the controls (0.8 vs -0.5, P = 0.044). Patients in the acupuncture group had a statistically significant decrease in procedure vital signs including heart rate (-1.8 vs 5.6, P = 0.043) and respiratory rate (-2.4 vs 0.4, P = 0.045) when compared with controls. Parents also perceived a correspondingly greater improvement in their child's pain for those in the acupuncture group compared with the controls (2.3 vs 0.3, P = 0.04). Adjunctive LA significantly improved pain after pediatric percutaneous kidney biopsies.

A secondary analysis of the telephone care Indiana Cancer Pain and Depression trial was performed. Patients (n = 274) were interviewed at baseline and after 1, 3, 6, and 12 months. Pain improvement outcomes included both a continuous measure (Brief Pain Inventory score) and a categorical measure (pain improved versus pain not improved). Predictor variables included change in depression, age, sex, race, marital status, socioeconomic disadvantage, medical comorbidity, type of cancer, and phase of cancer. Multivariable repeated measures were conducted, adjusting for intervention group assignment, baseline pain severity, and time in months since baseline assessment. Factors significantly predicting both continuous and categorical pain improvement included participating in the intervention group (β = -0.92, p < .001, odds ratio [OR] = 2.53, 95% confidence interval [CI] = 1.65-3.89), greater improvement in depression (β = -0.31, p = .003, OR = 1.84, 95% CI = 1.35-2.51), higher socioeconomic status (Socioeconomic Disadvantage index; β = 0.25, p = .034; OR = 0.73, 95% CI = 0.56-0.94), and fewer comorbid conditions (β = 0.20, p = .002; OR = 0.84, 95% CI = 0.73-0.96). Patients with more severe pain at baseline or with recurrent or progressive cancer were less likely to experience continuous or categorical pain improvement, respectively. Effective management of depression and comorbid conditions along with improvement of social services could be critical components of a comprehensive pain management. Patients with more severe pain or with recurrent or progressive cancers may require closer monitoring and adequate treatment of pain. Trial Registration clinicaltrials.gov Identifier: NCT00313573.

The review demonstrates the unique advantages of ultrasonography in pain control. Several imaging modalities can be used to guide pain control, such as computed tomography, magnetic resonance imaging, and radiography. Ultrasonography has unique advantages over these other modalities in terms of its non-ionizing radiation, real-time imaging, portability, and cost-effectiveness. Ultrasonography with color Doppler and elastography can provide safer guidance to avoid blood vessels and the nerve trunk when using steroid or xylocaine infusions to encase the nerve trunk. This review focuses on the control of chronic pain in the upper limbs, lower limbs, and trunk. Copyright © 2014. Published by Elsevier B.V.

The problem of cancer-related pain afflicts millions of people annually. The study described here was aimed at improving cancer patients' pain control through a planned patient education program. A randomized clinical trial with a Solomon Four-Group design was used to assess the effectiveness of a patient education intervention consisting of nurse counseling and printed materials. The sample included 230 cancer patients. One month later, patients in the experimental group were more likely to have taken their pain medicine on the correct schedule and to have taken the correct dosage. The experimental group also was significantly less likely to report stopping the medicine when they felt better. In addition, they were significantly less worried about tolerance and addiction to pain medicines. Forty-four percent of the experimental group compared to 24% of the control group reported no or mild pain at the posttest.

To determine whether an interactive self-management Website for people with chronic back pain would significantly improve emotional management, coping, self-efficacy to manage pain, pain levels, and physical functioning compared with standard text-based materials. The study utilized a pretest-posttest randomized controlled design comparing Website (painACTION-Back Pain) and control (text-based material) conditions at baseline and at 1-, 3, and 6-month follow-ups. Two hundred and nine people with chronic back pain were recruited through dissemination of study information online and at a pain treatment clinic. The 6-month follow-up rates for the Website and control groups were 73% and 84%, respectively. Measures were based on the recommendations of the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials and included measures of pain intensity, physical functioning, emotional functioning, coping, self-efficacy, fear-avoidance, perceived improvement with treatment, self-efficacy, and catastrophizing. Compared with controls, painACTION-Back Pain participants reported significantly: 1) lower stress; 2) increased coping self-statements; and 3) greater use of social support. Comparisons between groups suggested clinically significant differences in current pain intensity, depression, anxiety, stress, and global ratings of improvement. Among participants recruited online, those using the Website reported significantly: 1) lower "worst" pain; 2) lower "average" pain; and 3) increased coping self-statements, compared with controls. Participants recruited through the pain clinic evidenced no such differences. An online self-management program for people with chronic back pain can lead to improvements in stress, coping, and social support, and produce clinically significant differences in pain, depression, anxiety, and global rates of improvement.

Effective treatments for chronic spinal pain are essential to reduce the related high personal and socioeconomic costs. To compare pain neuroscience education combined with cognition-targeted motor control training with current best-evidence physiotherapy for reducing pain and improving functionality, gray matter morphologic features, and pain cognitions in individuals with chronic spinal pain. Multicenter randomized clinical trial conducted from January 1, 2014, to January 30, 2017, among 120 patients with chronic nonspecific spinal pain in 2 outpatient hospitals with follow-up at 3, 6, and 12 months. Participants were randomized into an experimental group (combined pain neuroscience education and cognition-targeted motor control training) and a control group (combining education on back and neck pain and general exercise therapy). Primary outcomes were pain (pressure pain thresholds, numeric rating scale, and central sensitization inventory) and function (pain disability index and mental health and physical health). There were 22 men and 38 women in the experimental group (mean [SD] age, 39.9 [12.0] years) and 25 men and 35 women in the control group (mean [SD] age, 40.5 [12.9] years). Participants in the experimental group experienced reduced pain (small to medium effect sizes): higher pressure pain thresholds at primary test site at 3 months (estimated marginal [EM] mean, 0.971; 95% CI, -0.028 to 1.970) and reduced central sensitization inventory scores at 6 months (EM mean, -5.684; 95% CI, -10.589 to -0.780) and 12 months (EM mean, -6.053; 95% CI, -10.781 to -1.324). They also experienced improved function (small to medium effect sizes): significant and clinically relevant reduction of disability at 3 months (EM mean, -5.113; 95% CI, -9.994 to -0.232), 6 months (EM mean, -6.351; 95% CI, -11.153 to -1.550), and 12 months (EM mean, -5.779; 95% CI, -10.340 to -1.217); better mental health at 6 months (EM mean, 36.496; 95% CI, 7.998-64.995); and better physical

To evaluate the effect of a group-based multidisciplinary rehabilitation programme on disability, pain and quality of life in subjects with chronic neck pain. Randomized controlled trial. Specialized rehabilitation centre. A total of 170 patients (mean age of 53 years (13); 121 females). The multidisciplinary group underwent a multidisciplinary rehabilitation programme combining multimodal exercises with psychologist-lead cognitive-behavioural therapy sessions. The general exercise group underwent general physiotherapy. Both groups followed group-based programmes once a week for ten weeks. Additionally, the multidisciplinary group met with the psychologist once a week for a 60-minute session. The Neck Disability Index (primary outcome), the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a pain numerical rating scale and the Short-Form Health Survey. The participants were evaluated before, after training and after 12 months. A linear mixed model for repeated measures was used for each outcome measure. Significant effects ( p-value <0.001) were found over time and between groups for all outcome measures. After training, significant improvements were found for both groups for all outcome measures except kinesiophobia and catastrophizing, which did not change in the control group; however, the improvements were significantly greater for the multidisciplinary group. At 12-month follow-up a clinically meaningful between-group difference of 12.4 Neck Disability Index points was found for disability. A group-based multidisciplinary rehabilitation programme including cognitive-behavioural therapy was superior to group-based general physiotherapy in improving disability, pain and quality of life of subjects with chronic neck pain. The effects lasted for at least one year.

This protocol presents the rationale and design for a trial evaluating the efficacy of intranasal oxytocin in improving pain and function among women with chronic pelvic musculoskeletal pain. Oxytocin is a neuropeptide traditionally recognised for involvement in labour, delivery and lactation. Novel evidence suggests that oxytocin decreases pain sensitivity in humans. While oxytocin administration has been reported to lower pain sensitivity among patients experiencing chronic back pain, headache, constipation and colon pain, no research has evaluated the association between intranasal oxytocin and chronic pelvic musculoskeletal pain. The association between oxytocin and pain may differ in women with chronic pelvic musculoskeletal pain relative to other chronic pain conditions because of the abundance of oxytocin receptors in the uterus. This is a prospective, randomised, placebo-controlled, double-blind, within-participants crossover trial. 50 women with chronic pelvic musculoskeletal pain will be recruited through a local chronic pain centre and gynaecology clinics. Women will complete baseline measures and be randomised to an experimental or control condition that involve 2 weeks of self-administering twice-daily doses of 24 IU intranasal oxytocin or placebo, respectively. Women will then undergo a 2-week washout period before crossing over to receive the condition that they had not yet received. The primary outcome will be pain and function measured using the Brief Pain Inventory-Short Form. Secondary outcomes include emotional function, sleep disturbance and global impression of change. This trial will provide data on the 14-day safety and side-effect profile of intranasal oxytocin self-administered as an adjuvant treatment for chronic pelvic musculoskeletal pain. This trial was granted approval from Health Canada and the University of Calgary Conjoint Health Research Ethics Board, and is registered online at ClinicalTrials.gov (#NCT02888574). Results will

To determine whether spa therapy has a beneficial effect on pain and disability in patients with chronic shoulder pain, this single-blind randomised controlled clinical trial included patients with chronic shoulder pain due to miscellaneous conditions attending one of four spa centres as outpatients. Patients were randomised into two groups: spa therapy (18 days of standardised treatment combining thermal therapy together with supervised mobilisation in a thermal pool) and controls (spa therapy delayed for 6 months: `immediate versus delayed treatment' paradigm). All patients continued usual treatments during the 6-month follow-up period. The main endpoint was the mean change in the French-Quick DASH (F-QD) score at 6 months. The effect size of spa therapy was calculated, and the proportion of patients reaching minimal clinically important improvement (MCII) was compared. Secondary endpoints were the mean change in SF-36, treatment use and tolerance. One hundred eighty-six patients were included (94 patients as controls, 92 in the spa group) and analysed by intention to treat. At 6 months, the mean change in the F-QD score was statistically significantly greater among spa therapy patients than controls (- 32.6 versus - 8.15%; p < 0.001) with an effect size of 1.32 (95%CI: 0.97-1.68). A significantly greater proportion of spa therapy patients reached MCII (59.3 versus 17.9%). Spa therapy was well tolerated with a significant impact on SF-36 components but not on drug intake. Spa therapy provided a statistically significant benefit on pain, function and quality of life in patients with chronic shoulder pain after 6 months compared with usual care.

To investigate the effects of the CORE programme on pain at rest, movement-induced pain, secondary pain, active range of motion, and proprioception deficits in female office workers with chronic low back pain. Randomized controlled trial. Rehabilitation clinics. A total of 53 participants with chronic low back pain were randomized into the CORE group and the control group. CORE group participants underwent the 30-minute CORE programme, five times per week, for eight weeks, with additional use of hot-packs and transcutaneous electrical nerve stimulation, while the control group used only hot-packs and transcutaneous electrical nerve stimulation. Participants were evaluated pretest, posttest, and two months after the intervention period to measure resting and movement-induced pain, pressure pain as secondary pain, active range of pain-free motion, and trunk proprioception. Pain intensity at rest (35.6 ±5.9 mm) and during movement (39.4 ±9.1 mm) was significantly decreased in the CORE group following intervention compared with the control group. There were significant improvements in pressure pain thresholds (quadratus lumborum: 2.2 ±0.7 kg/cm(2); sacroiliac joint: 2.0 ±0.7 kg/cm(2)), active range of motion (flexion: 30.8 ±14.3°; extension: 6.6 ±2.5°), and proprioception (20° flexion: 4.3 ±2.4°; 10° extension: 3.1 ±2.0°) in the CORE group following intervention (all p < 0.05). These improvements were maintained at the two-month follow-up. The control group did not show significant improvements in any measured parameter. The CORE programme is an effective intervention for reducing pain at rest and movement-induced pain, and for improving the active range of motion and trunk proprioception in female office workers with chronic low back pain. © The Author(s) 2014.

Pain is an extremely common complaint in primary care, and patient outcomes are often suboptimal. This project evaluated the impact of Project ECHO Pain videoconference case-based learning sessions on knowledge and quality of pain care in two Federally Qualified Health Centers. Quasi-experimental, pre-post intervention, with comparison group. Two large, multisite federally qualified health centers in Connecticut and Arizona. Intervention (N = 10) and comparison (N = 10) primary care providers. Primary care providers attended 48 weekly Project ECHO Pain sessions between January and December 2013, led by a multidisciplinary pain specialty team. Surveys and focus groups assessed providers' pain-related knowledge and self-efficacy. Electronic health record data were analyzed to evaluate opioid prescribing and specialty referrals. Compared with control, primary care providers in the intervention had a significantly greater increase in pain-related knowledge and self-efficacy. Providers who attended ECHO were more likely to use formal assessment tools and opioid agreements and refer to behavioral health and physical therapy compared with control providers. Opioid prescribing decreased significantly more among providers in the intervention compared with those in the control group. Pain is an extremely common and challenging problem, particularly among vulnerable patients such as those cared for at the more than 1,200 Federally Qualified Health Centers in the United States. In this study, attendance at weekly Project ECHO Pain sessions not only improved knowledge and self-efficacy, but also altered prescribing and referral patterns, suggesting that knowledge acquired during ECHO sessions translated into practice changes. © 2017 American Academy of Pain Medicine.

Descending pain inhibition suppresses spinal nociception, reducing nociceptive input to the brain. It is modulated by cognitive and emotional processes. In subjects with chronic pain, it is impaired, possibly contributing to pain persistence. A previously developed feedback method trains subjects to activate their descending inhibition. Participants are trained to use cognitive-emotional strategies to reduce their spinal nociception, as quantified by the nociceptive flexor reflex (RIII reflex), under visual feedback about their RIII reflex size. The aim of the present study was to test whether also subjects with chronic back pain can achieve a modulation of their descending pain inhibition under RIII feedback. In total, 33 subjects with chronic back pain received either true (n = 18) or sham RIII feedback (n = 15), 15 healthy control subjects received true RIII feedback. All three groups achieved significant RIII suppression, largest in controls (to 76 ± 26% of baseline), intermediate in chronic back pain subjects receiving true feedback (to 82 ± 13%) and smallest in chronic back pain subjects receiving sham feedback (to 89 ± 14%, all p < 0.05). However, only chronic pain subjects receiving true feedback significantly improved their descending inhibition over the feedback training, quantified by the conditioned pain modulation effect (test pain reduction of baseline before training: to 98 ± 26%, after: to 80 ± 21%, p < 0.01). Our results show that subjects with chronic back pain can achieve a reduction of their spinal nociception and improve their descending pain inhibition under RIII feedback training. Subjects with chronic back pain can learn to control their spinal nociception, quantified by the RIII reflex, when they receive feedback about the RIII reflex. © 2017 European Pain Federation - EFIC®.

Objective To examine whether an off-axis elliptical training program reduces pain and improves knee function in individuals with patellofemoral pain (PFP). Design Controlled laboratory study, pre-test-post-test. Setting University rehabilitation center. Participants Twelve adult subjects with PFP. Interventions Subjects with PFP completed an exercise program consisting of 18 sessions of lower extremity off-axis training using a custom-made elliptical trainer that allows frontal-plane sliding and transverse-plane pivoting of the footplates. Main Outcome Measures Changes in knee pain and function post-training and 6 weeks following training were evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee (IKDC) scores. Lower extremity off-axis control was assessed by pivoting and sliding instability, calculated as the root mean square (RMS) of the footplate pivoting angle and sliding distance during elliptical exercise. Subjects’ single-leg hop distance and proprioception in detecting lower extremity pivoting motion were also evaluated. Results Subjects reported significantly greater KOOS and IKDC scores (increased by 12–18 points) and hop distance (increased by 0.2 m) following training. A significant decrease in the pivoting and sliding RMS was also observed following training. Additionally, subjects with PFP demonstrated improved pivoting proprioception when tested under a minimum-weight-bearing position. Conclusions An off-axis elliptical training program was effective in enhancing lower extremity neuromuscular control on the frontal and transverse planes, reducing pain and improving knee function in persons with PFP.

Chronic abdominal pain (CAP) in childhood is widely prevalent and has adverse effects on mental health and quality of life. Earlier research emphasized the positive effects of psychological intervention on pain symptoms. This study describes the results of a cognitive-behavioral pain management program for children with CAP. The newly developed cognitive-behavioral group program, "Stop the pain with Happy-Pingu," includes six sessions for the children and one meeting for the parents. We hypothesized that the training would significantly reduce pain symptoms (frequency, duration, intensity, and pain-related impairment) and increase health-related quality of life compared to wait-list controls, with improvement seen both at the end of treatment and at a 3-month follow-up. In all, 29 children were randomized into two groups: 15 in the intervention group (IG) and 14 as the wait-list controls (WLC). An intent-to-treat analysis was performed using two-factorial multivariate analyses of variance with repeated measures. Children in the IG experienced both a reduction in pain (primary outcome) and an improvement in health-related quality of life (secondary outcome) as compared to the WLC. The effect sizes ranged from medium to high. Cognitive-behavioral methods seem to be appropriate for treating children with CAP.

Previous research suggests that self-management programs for people with chronic pain improve knowledge and self-efficacy but result in negligible effects on function. This study will investigate the effectiveness self-management support with pain science education and exercise on improving function for people with chronic pain in comparison to a wait-list control. A secondary objective is to determine which variables help to predict response to the intervention. This study will be an unblinded, randomized controlled trial with 110 participants comparing a 6-week program that includes self-management support, pain science education and exercise to a wait-list control. The primary outcome will be function measured by the Short Musculoskeletal Function Assessment - Dysfunction Index. Secondary outcomes will include pain intensity measured by a numeric pain rating scale, pain interference measured by the eight-item PROMIS pain interference item-bank, how much patients are bothered by functional problems measured by the Short Musculoskeletal Function Assessment - Bother Index, catastrophic thinking measured by the Pain Catastrophizing Scale, fear of movement/re-injury measured by the 11-item Tampa Scale of Kinesiophobia, sense of perceived injustice measured by the Injustice Experience Questionnaire, self-efficacy measured by the Pain Self-Efficacy Questionnaire, pain sensitivity measured by pressure pain threshold and cold sensitivity testing, fatigue measured by a numeric fatigue rating scale, pain neurophysiology knowledge measured by the Neurophysiology of Pain Questionnaire, healthcare utilization measured by number of visits to a healthcare provider, and work status. Assessments will be completed at baseline, 7 and 18 weeks. After the 18-week assessment, the groups will crossover; however, we anticipate carry-over effects with the treatment. Therefore, data from after the crossover will be used to estimate within-group changes and to determine predictors of

Low back pain causes more global disability than any other condition. Once the acute pain becomes chronic, about two-thirds of sufferers will not fully recover after 1-2 years. There is a paucity of effective treatments for non-specific, chronic low back pain. It has been noted that low back pain is associated with changes in the connective tissue in the affected area, and a very low-impact treatment, Esoteric Connective Tissue Therapy (ECTT), has been developed to restore flexibility in connective tissue. ECTT uses patterns of very small, circular movements, to the legs, arms, spine, sacrum and head, which anecdotally are effective in pain relief. In an unpublished single-arm phase I/II trial with chronic pain patients, ECTT showed a 56% reduction in pain after five treatments and 45% and 54% improvements at 6 months and 7-9 years of follow-up respectively. The aim of this randomised controlled trial is to compare ECTT with physiotherapy for reducing pain and improving physical function and physical and mental well-being in patients with chronic low back pain. The trial will be held at two hospitals in Vietnam. One hundred participants with chronic low back pain greater than or equal to 40/100 on the visual analogue scale will be recruited and randomised to either ECTT or physiotherapy. Four weekly treatments will be provided by two experienced ECTT practitioners (Treatment Group, 40 minutes each) and hospital-employed physiotherapy nurses (Control Group, 50 minutes). The primary outcomes will be changes in pain, physical function per the Quebec Pain Functionality Questionnaire and physical and mental well-being recorded by the Short Form Health Survey (SF-36), with mixed modelling used as the primary statistical tool because the data are longitudinal. Initial follow-up will be at either 4 or 8 months, with a second follow-up after 12 months. The trial design has important strengths, because it is to be conducted in hospitals under medical supervision

To investigate the effect of pain neurophysiology education (PNE) on student physiotherapists': (1) knowledge of chronic pain; (2) attitudes towards patients with chronic pain; and (3) clinical recommendations for patients with chronic pain. Multicentre single-blind randomised controlled trial. One UK and one Irish university. Seventy-two student physiotherapists. Participants received either PNE (intervention) or a control education. Both were delivered in a 70-minute group lecture. (1) The Revised Pain Neurophysiology Quiz to assess knowledge; (2) the Health Care Pain Attitudes and Impairment Relationship Scale (HC-PAIRS) to assess attitudes; and (3) a case vignette to assess the appropriateness of clinical recommendations. Post education, the PNE group had a greater increase in pain neurophysiology knowledge [mean difference 4.0 (95% confidence interval 3.2 to 4.7), P<0.01] and more improved attitudes [-17.5 (95% confidence interval -22.1 to -12.9), P<0.01] compared with the control group. Post education, students in the PNE group were more likely to make appropriate recommendations regarding work (94% vs 56%), exercise (92% vs 56%), activity (94% vs 67%) and bed rest (69% vs 33%) compared with those in the control group (P<0.05). The improvements in knowledge, attitudes and recommendations for pain management show that PNE is a potentially valuable part of the education of physiotherapy students, and could be used on a more widespread basis. There is a need to investigate whether these findings can be replicated in other healthcare professions, and how well these reported changes lead to changes in actual clinical behaviour and the clinical outcomes of patients.

Advances being made in improving access to HIV drugs in resource-poor countries mean HIV patients are living longer, and, therefore, experiencing pain over a longer period of time. There is a need to provide effective interventions for alleviating and managing pain. To assess whether a pain educational intervention compared with usual care reduces pain severity and improves pain management in patients with HIV/AIDS and their family carers. This was a randomized, parallel group, superiority trial conducted at HIV and palliative care clinics of two public hospitals in Malawi. A total of 182 adults with HIV/AIDS (Stage III or IV) and their family carers participated; carer participants were those individuals most involved in the patient's unpaid care. The educational intervention comprised a 30 minute face-to-face meeting, a leaflet, and a follow-up telephone call at two weeks. The content of the educational intervention covered definition, causes, and characteristics of pain in HIV/AIDS; beliefs and myths about pain and pain medication; assessment of pain; and pharmacological and nonpharmacological management. The primary outcome was average pain severity measured by the Brief Pain Inventory-Pain Severity subscale. Assessments were recorded at baseline before randomization and at eight weeks after randomization. Of the 182 patient/carer dyads randomly allocated, 157 patient/carer dyads completed the trial. Patients in the intervention group experienced a greater decrease in pain severity (mean difference = 21.09 points, 95% confidence interval = 16.56-25.63; P < 0.001). A short pain education intervention is effective in reducing pain and improving pain management for Malawian people living with HIV/AIDS and their family carers.

There is evidence that virtual reality (VR) pain distraction is effective at improving pain-related outcomes. However, more research is needed to investigate VR environments with other pain-related goals. The main aim of this study was to compare the differential effects of two VR environments on a set of pain-related and cognitive variables during a cold pressor experiment. One of these environments aimed to distract attention away from pain (VRD), whereas the other was designed to enhance pain control (VRC). Participants were 77 psychology students, who were randomly assigned to one of the following three conditions during the cold pressor experiment: (a) VRD, (b) VRC, or (c) Non-VR (control condition). Data were collected regarding both pain-related variables (intensity, tolerance, threshold, time perception, and pain sensitivity range) and cognitive variables (self-efficacy and catastrophizing). Results showed that in comparison with the control condition, the VRC intervention significantly increased pain tolerance, the pain sensitivity range, and the degree of time underestimation. It also increased self-efficacy in tolerating pain and led to a reduction in reported helplessness. The VRD intervention significantly increased the pain threshold and pain tolerance in comparison with the control condition, but it did not affect any of the cognitive variables. Overall, the intervention designed to enhance control seems to have a greater effect on the cognitive variables assessed. Although these results need to be replicated in further studies, the findings suggest that the VRC intervention has considerable potential in terms of increasing self-efficacy and modifying the negative thoughts that commonly accompany pain problems.

This study aimed to develop a multimedia video CD (VCD) of patient-controlled analgesia (PCA) and test its effects on pain knowledge and pain relief in patients receiving surgery. This multimedia VCD of PCA was created to convey fundamental knowledge to both patients and their family members and help patients properly utilize PCA devices to relieve pain and improve recovery. The content of multimedia VCD of PCA included pre-admission pain education, introduction of PCA, nursing care procedures, and questions and answers. This study used a quasi-experimental research design to test effects of the multimedia education program in the experimental group of 30 subjects compared to the control subjects of equal number (without the multimedia VCD of PCA). (1) The intervention of multimedia VCD of PCA resulted in a statistically significant difference in pain knowledge between the experimental and control groups. (2) Subjects in the experimental group obtained a better outcome of pain relief compared to control subjects. (3) Subjects in the experimental group indicated that the multimedia VCD of PCA indeed helped them effectively operate their PCA devices to relieve surgery pain. The clinical application of the multimedia VCD of PCA could help patients improve knowledge on pain, learn how to use PCA devices, achieve proper pain relief, and increase effectiveness of recovery activities.

Many traumatized refugees experience both posttraumatic stress disorder and chronic pain. Based on Mutual Maintenance Theory and the Perpetual Avoidance Model, this study examined the additional effect of physical activity within a biofeedback-based cognitive behavioral therapy (CBT-BF) for traumatized refugees. In a controlled design, 36 patients were randomized into one of three conditions (CBT-BF, CBT-BF with physical activity [CBT-BF+active], and a waiting list control group [WL]). Thirty patients (n=10 in each group) completed the treatment and a follow-up assessment 3 months later. Participants' coping strategies, pain and mental health status, and physiological reactivity were assessed before and after the intervention and at 3-month follow-up. Treatment effects were analyzed using analyses of variance with baseline scores as covariates (ANCOVAs) and the Reliable Change Index. The CBT-BF and CBT-BF+active groups showed improvements in all outcome measures relative to the WL group. The effect sizes for the main outcome measures were higher in the CBT-BF+active group than in the CBT-BF group. Repeated measures analyses of covariance showed significant group effects for coping strategies--in particular, for the "cognitive restructuring" and "counter-activities" subscales as well as a marginally significant group effect for "perceived self-competence"--with the CBT-BF+active group showing more favorable outcomes than the CBT-BF group. Moreover, 60% of participants in the CBT-BF+active group showed clinically reliable intraindividual change in at least one subscale of the pain coping strategies questionnaire, compared with just 30% of participants in the CBT-BF group. Findings of improved coping strategies, larger effect sizes, and higher rates of clinical improvement in the CBT-BF+active group suggest that physical activity adds value to pain management interventions for traumatized refugees. Given the small sample size, however, these preliminary results need

Effective communication is needed for optimal cancer pain management. This study assessed the efficacy of a general communication skills training program for oncology nurses on communication about pain management. A total of 115 nurses were randomly assigned to a training group (TG) or control group (CG). The assessment included the recording of interviews with a simulated cancer patient at baseline for both groups and after training (TG) or 3 months after baseline (CG). Two psychologists rated the content of interview transcripts to assess cancer pain management communication. Group-by-time effects were measured using a generalized estimating equation. Trained nurses asked the simulated patient more questions about emotions associated with pain (relative rate [RR] = 4.28, p = 0.049) and cognitions associated with pain treatment (RR = 3.23, p < 0.001) and used less paternalistic statements about cancer pain management (RR = 0.40, p = 0.006) compared with untrained nurses. The general communication skills training program improved only a few of the communication strategies needed for optimal cancer pain management in nursing. General communication skills training programs should be consolidated using specific modules focusing on communication skills related to cancer pain management.

Tantawy, Sayed A; Kamel, Dalia M; Abdelbasset, Walid Kamal

2018-01-01

Background Chronic orchialgia is defined as testicular pain, which may be either unilateral or bilateral, lasting for more than 3 months. It disturbs a patient’s daily activities and quality of life (QoL), inciting the patient to search for treatments to alleviate the pain. It is estimated that 25% of chronic orchialgia cases are idiopathic. Purpose The purpose of this study was to investigate how effective transcutaneous electrical nerve stimulation (TENS) is in pain reduction and how it consequently affects the QoL in patients with idiopathic chronic orchialgia (ICO). Patients and methods Seventy-one patients were randomly assigned to group A (study group), which included 36 patients who received TENS and analgesia, and group B (control group), which included 35 patients who received analgesia only. The outcome measures were the participants’ demographic data and results of the visual analog scale (VAS) and QoL questionnaire. These outcomes were measured before and after 4 weeks of treatment and at 2-month follow-up. Results The results showed that compared to pretreatment, there was a significant reduction in pain postintervention and at 2-month follow-up in group A (P<0.0001 and <0.001, respectively; F=7.1) as well as a significant improvement in QoL at these time points (P<0.0001 and <0.0001, respectively). There were no significant differences in the VAS score and QoL in group B at different time points of evaluation. Conclusion The findings indicate that TENS is effective in reducing pain and improving patients’ QoL in cases of ICO. TENS is an easy-to-use, effective, noninvasive, and simple method for ICO-associated pain control and QoL improvement. PMID:29343983

[QUIPS: quality improvement in postoperative pain management].

Despite the availability of high-quality guidelines and advanced pain management techniques acute postoperative pain management is still far from being satisfactory. The QUIPS (Quality Improvement in Postoperative Pain Management) project aims to improve treatment quality by means of standardised data acquisition, analysis of quality and process indicators, and feedback and benchmarking. During a pilot phase funded by the German Ministry of Health (BMG), a total of 12,389 data sets were collected from six participating hospitals. Outcome improved in four of the six hospitals. Process indicators, such as routine pain documentation, were only poorly correlated with outcomes. To date, more than 130 German hospitals use QUIPS as a routine quality management tool. An EC-funded parallel project disseminates the concept internationally. QUIPS demonstrates that patient-reported outcomes in postoperative pain management can be benchmarked in routine clinical practice. Quality improvement initiatives should use outcome instead of structural and process parameters. The concept is transferable to other fields of medicine. Copyright © 2011.

Pain facilitation and pain inhibition during conditioned pain modulation in fibromyalgia and in healthy controls.

PubMed

Potvin, Stéphane; Marchand, Serge

2016-08-01

Although fibromyalgia (FM) is associated with a deficit in inhibitory conditioned pain modulation (CPM), the discriminative power of CPM procedures is unknown. Moreover, the high intersubject heterogeneity in CPM responses in FM raises the possibility that a sizeable subgroup of these patients may experience pain facilitation during CPM, but the phenomenon has not been explicitly studied. To address these issues, 96 patients with FM and 71 healthy controls were recruited. Thermal stimuli were used to measure pain thresholds. Pain inhibition was elicited using a tonic thermal test (Peltier thermode) administered before and after activation of CPM mechanisms using a cold pressor test. Thermal pain thresholds were lower in patients with FM than in healthy controls. Pain ratings during the cold pressor test were higher in patients with FM, relative to controls. The CPM inhibitory efficacy was lower in patients with FM than in controls. The CPM procedure had good specificity (78.9%) but low sensitivity (45.7%), whereas a composite pain index had good sensitivity (75.0%) and specificity (78.9%). Finally, the rate of patients with FM who reported pain facilitation during the CPM procedure was found to be significantly increased compared with that of controls (41.7% vs 21.2%). The good discriminative power of the composite pain index highlights the need for further validation studies using mechanistically relevant psychophysical procedures in FM. The low sensitivity of the CPM procedure, combined with the large proportion of patients with FM experiencing pain facilitation during CPM, strongly suggests that endogenous pain inhibition mechanisms are deeply impaired in patients with FM, but only in a subgroup of them.

Available evidence favors the use of pain neuroscience education (PNE) in patients with chronic pain. However, PNE trials are often limited to small sample sizes and, despite the current digital era, the effects of blended-learning PNE (ie, the combination of online digital media with traditional educational methods) have not yet been investigated. The study objective was to examine whether blended-learning PNE is able to improve disability, catastrophizing, kinesiophobia, and illness perceptions. This study was a 2-center, triple-blind randomized controlled trial (participants, statistician, and outcome assessor were masked). The study took place at university hospitals in Ghent and Brussels, Belgium. Participants were 120 people with nonspecific chronic spinal pain (ie, chronic neck pain and low back pain). The intervention was 3 sessions of PNE or biomedically focused back/neck school education (addressing spinal anatomy and physiology). Measurements were self-report questionnaires (Pain Disability Index, Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, Illness Perception Questionnaire, and Pain Vigilance and Awareness Questionnaire). None of the treatment groups showed a significant change in the perceived disability (Pain Disability Index) due to pain (mean group difference posteducation: 1.84; 95% CI = -2.80 to 6.47). Significant interaction effects were seen for kinesiophobia and several subscales of the Illness Perception Questionnaire, including negative consequences, cyclical time line, and acute/chronic time line. In-depth analysis revealed that only in the PNE group were these outcomes significantly improved (9% to 17% improvement; 0.37 ≤ Cohen d ≥ 0.86). Effect sizes are small to moderate, which might raise the concern of limited clinical utility; however, changes in kinesiophobia exceed the minimal detectable difference. PNE should not be used as the sole treatment modality but should be combined with other treatment strategies

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

Cancer pain is prevalent, yet patients do not receive best care despite widely available evidence. Although national cancer control policies call for education, effectiveness of such programs is unclear and best practices are not well defined. To examine existing evidence on whether knowledge translation (KT) interventions targeting health care providers, patients, and caregivers improve cancer pain outcomes. A systematic review and meta-analysis were undertaken to evaluate primary studies that examined effects of KT interventions on providers and patients. Twenty-six studies met the inclusion criteria. Five studies reported interventions targeting health care providers, four focused on patients or their families, one study examined patients and their significant others, and 16 studies examined patients only. Seven quantitative comparisons measured the statistical effects of interventions. A significant difference favoring the treatment group in least pain intensity (95% confidence interval [CI]: 0.44, 1.42) and in usual pain/average pain (95% CI: 0.13, 0.74) was observed. No other statistical differences were observed. However, most studies were assessed as having high risk of bias and failed to report sufficient information about the intervention dose, quality of educational material, fidelity, and other key factors required to evaluate effectiveness of intervention design. Trials that used a higher dose of KT intervention (characterized by extensive follow-up, comprehensive educational program, and higher resource allocation) were significantly more likely to have positive results than trials that did not use this approach. Further attention to methodological issues to improve educational interventions and research to clarify factors that lead to better pain control are urgently needed. Crown Copyright © 2011.

The American Pain Society (APS) set out to revise and expand its 1995 Quality Improvement Guidelines for the Treatment of Acute Pain and Cancer Pain and to facilitate improvements in the quality of pain management in all care settings. Eleven multidisciplinary members of the APS with expertise in quality improvement or measurement participated in the update. Five experts from organizations that focus on health care quality reviewed the final recommendations. MEDLINE and Cumulative Index to Nursing and Allied Health Literature databases were searched (1994-2004) to identify articles on pain quality measurement and quality improvement published after the development of the 1995 guidelines. The APS task force revised and expanded recommendations on the basis of the systematic review of published studies. The more than 3000 members of the APS were invited to provide input, and the 5 experts provided additional comments. The task force synthesized reviewers' comments into the final set of recommendations. The recommendations specify that all care settings formulate structured, multilevel systems approaches (sensitive to the type of pain, population served, and setting of care) that ensure prompt recognition and treatment of pain, involvement of patients and families in the pain management plan, improved treatment patterns, regular reassessment and adjustment of the pain management plan as needed, and measurement of processes and outcomes of pain management. Efforts to improve the quality of pain management must move beyond assessment and communication of pain to implementation and evaluation of improvements in pain treatment that are timely, safe, evidence based, and multimodal.

Pain is reported to occur in the majority of patients with advanced cancer and is one of the main reasons for referral to a hospital specialist palliative care team. Yet despite this, there is a paucity of research into the impact the hospital specialist palliative care team has on pain control in patients. A non-equivalent control group design using a quota sample investigated 100 cancer patients who had been admitted to hospital for symptom control. Fifty patients received specialist hospital palliative care team intervention compared with 50 patients receiving traditional care. Outcome was assessed using the Palliative Care Assessment (PACA) tool on three occasions. There was no difference between the groups on the initial assessment and the results indicated that all cancer patients admitted to hospital had a significant improvement in their pain control. However, the patients who had the additional input of the palliative care team demonstrated a statistically significant greater improvement than the control group (P<0.001). Potential explanations are made for the results including the enhanced knowledge and skills of the hospital specialist palliative care team.

First-trimester abortions especially cervical dilation and suction aspiration are associated with pain despite various methods of pain control. Following the guidelines for a Cochrane review, we systematically searched for and reviewed randomized controlled trials comparing methods of pain control in first-trimester surgical abortion at less than 14 weeks gestational age using electric or manual suction aspiration. Outcomes included intra- and postoperative pain, side effects, recovery measures and satisfaction. We included 40 trials with 5131 participants. Because of heterogeneity, we divided studies into seven groups: Local anesthesia: Data were insufficient to show a clear benefit of a paracervical block (PCB) compared to no PCB. Reported mean pain scores (10-point scale) during dilation and aspiration were improved with carbonated lidocaine [weighted mean difference (WMD), -0.80; 95% confidence interval (CI), -0.89 to -0.71; WMD, -0.96; 95% CI, -1.67 to -0.25], deep injection (WMD, -1.64; 95% CI, -3.21 to -0.08; WMD, 1.00; 95% CI, 1.09 to 0.91), and with adding a 4% intrauterine lidocaine infusion (WMD, -2.0; 95% CI, -3.29 to -0.71; WMD, -2.8; 95% CI, -3.95 to -1.65). PCB with premedication: Ibuprofen and naproxen resulted in small reduction of intra- and postoperative pain. Conscious sedation: The addition of conscious intravenous sedation using diazepam and fentanyl to PCB decreased procedural pain. General anesthesia: Conscious sedation increased intraoperative but decreased postoperative pain compared to general anesthesia (GA) [Peto odds ratio (Peto OR) 14.77 (95%, CI 4.91-44.38) and Peto OR 7.47 (95% CI, 2.2-25.36) for dilation and aspiration, respectively, and WMD -1.00 (95% CI, -1.77 to -0.23) postoperatively). Inhalation anesthetics are associated with increased blood loss (p<0.001). GA with premedication: The cyclooxygenase (COX)-2 inhibitor etoricoxib; the nonselective COX inhibitors lornoxicam, diclofenac and ketorolac IM; and the opioid nalbuphine

To evaluate short- and intermediate-term effects of kinematic training (KT) using virtual reality (VR) or laser in patients with chronic neck pain. A randomised controlled trial with three arms (laser, VR, control) to post-intervention (N = 90), and two arms (laser or VR) continuing to 3 months follow-up. Home training intervention was provided during 4 weeks to VR and laser groups while control group waited. Primary outcome measures included neck disability index (NDI), global perceived effect (GPE), and cervical motion velocity (mean and peak). Secondary outcome measures included pain intensity (VAS), health status (EQ5D), kinesiophobia (TSK), range, smoothness, and accuracy of neck motion as measured by the neck VR system. Measures were taken at baseline, immediately post-training, and 3 months later. Ninety patients with neck pain were randomised to the trial, of which 76 completed 1 month follow-up, and 56 the 3 months follow-up. Significant improvements were demonstrated in NDI and velocity with good effect sizes in intervention groups compared to control. No within-group changes were presented in the control group, compared to global improvements in intervention groups. Velocity significantly improved at both time points in both groups. NDI, VAS, EQ5D, TSK and accuracy significantly improved at both time points in VR and in laser at 3 months evaluation in all but TSK. GPE scores showed 74-84% of participants perceived improvement and/or were satisfied. Significant advantages to the VR group compared to laser were found in velocity, pain intensity, health status and accuracy at both time points. The results support home kinematic training using VR or laser for improving disability, neck pain and kinematics in the short and intermediate term with an advantage to the VR group. The results provide directions for future research, use and development. ACTRN12615000231549.

Objectives This study aims to describe what adults with chronic pain experience in their role as parents, utilizing quantitative and qualitative methods. The first aim is to compare parents with chronic pain to parents without chronic pain on perceptions of their adolescent’s pain, parental response to pain, and catastrophizing beliefs about pain. The study also examined predictors of parental protective behaviors, and examined whether these associations differed by study group. Methods Parents with chronic pain (n=58) and parents without chronic pain (n=72) participated, and completed questionnaire measures of pain characteristics and pain interference, as well as measures of parental catastrophizing and protective pain responses. Parents with chronic pain also completed a structured interview about their experience of being a parent. Interview responses were videotaped and subsequently coded for content. Results Compared to controls, parents with chronic pain endorsed more pain in their adolescents, and were more likely to catastrophize about their adolescent’s pain and respond with protective behaviors. Parent’s own pain interference and the perception of higher pain in their adolescent was associated with increased protective parenting in the chronic pain group. Qualitative coding revealed a number of areas of common impact of chronic pain on parenting. Discussion Chronic pain impacts everyday parenting activities and emotions, and impacts pain-specific parent responses that are known to be related to increased pain and pain catastrophizing in children and adolescents. Parents with chronic pain might benefit from interventions that address potential parenting difficulties, and might improve outcomes for their children. PMID:25232862

Local anesthetic delivery via surgical drain provides improved pain control versus direct skin infiltration following axillary node dissection for breast cancer.

Axillary node dissection has a central role in the surgical management of breast cancer; however, it is associated with a significant risk of lymphoedema and chronic pain. Peri-operative administration of local anesthesia reduces acute and persistent post-surgical pain, but there is currently no consensus on the optimal method of local anesthetic delivery. Patients undergoing axillary dissection for breast cancer were randomly assigned to receive a one-off dose of levobupivacaine 0.5% (up to 2 mg/kg) following surgery, either via the surgical drain or by direct skin infiltration. Post-operative pain control at rest and on shoulder abduction was assessed using a numerical rating scale. Total analgesia consumption 48 h after surgery was also recorded. Pain scores were significantly lower when local anesthesia was administered via surgical drain at both 3 and 12 h after surgery; this trend extended to 24 h post-operatively. However, pain scores on shoulder abduction did not differ at the 12 or 24 h time points. No differences were found in the total analgesia consumption or length of hospital stay between treatment groups. This study demonstrates that local anesthetic delivery via a surgical drain provides improved pain control compared to direct skin infiltration following axillary node dissection. This is likely to be important for the management of acute pain in the immediate post-operative period; however, further studies may be required to validate this in specific patient subgroups, e.g., breast-conserving surgery versus mastectomy.

Fibromyalgia (FM) is a chronic pain disorder with patients frequently suffering from comorbid conditions, including osteoarthritis (OA). Data on how FM patients with comorbid OA respond to recommended therapies (such as pregabalin) could help their treatment. This was a pooled exploratory analysis of three randomized placebo-controlled clinical trials of pregabalin in FM patients to assess the impact of comorbid OA on the response to pregabalin. Patients were divided into those with and without comorbid OA. Difference in change in least squares (LS) mean pain score at endpoint (assessed by 0-10 numeric rating scale, controlled for baseline pain score) with pregabalin (300 mg/day and 450 mg/day) vs placebo was assessed. Changes in Patient Global Impression of Change (PGIC) responders and Fibromyalgia Impact Questionnaire (FIQ) total score were also assessed. There were 1665 patients in the analysis set (558, placebo; 552, pregabalin 300 mg/day; 555, pregabalin 450 mg/day), including 296 with comorbid OA. Pregabalin 450 mg/day significantly improved the LS mean (95% confidence interval) difference in pain score vs placebo in patients with (0.99 [0.44, 1.55], P < 0.001), and without (0.64 [0.39, 0.89], P < 0.001) OA. Improvements with pregabalin 300 mg/day with (0.31 [-0.25, 0.86], P = 0.276) and without (0.51 [0.25, 0.76], P < 0.001) OA were not consistently significant. Improvements in PGIC and FIQ total score were observed in patients with and without comorbid OA. FM patients with or without comorbid OA respond to treatment with pregabalin 450mg/day with significant improvements in pain intensity scores. These data could provide guidance to healthcare professionals treating these patients. © 2016 American Academy of Pain Medicine. All rights reserved.

The aim of this study was to investigate the ability of a glucosamine-containing supplement to improve locomotor functions in subjects with knee pain. A randomized, double-blind, placebo-controlled, parallel-group comparative study was conducted for 16 weeks in 100 Japanese subjects (age, 51.8±0.8 years) with knee pain. Subjects were randomly assigned to one of the two supplements containing 1) 1,200 mg of glucosamine hydrochloride, 60 mg of chondroitin sulfate, 45 mg of type II collagen peptides, 90 mg of quercetin glycosides, 10 mg of imidazole peptides, and 5 μg of vitamin D per day (GCQID group, n=50) or 2) a placebo (placebo group, n=50). Japanese Knee Osteoarthritis Measure, visual analog scale score, normal walking speed, and knee-extensor strength were measured to evaluate the effects of the supplement on knee-joint functions and locomotor functions. In subjects eligible for efficacy assessment, there was no significant group × time interaction, and there were improvements in knee-joint functions and locomotor functions in both groups, but there was no significant difference between the groups. In subjects with mild-to-severe knee pain at baseline, knee-extensor strength at week 8 (104.6±5.0% body weight vs 92.3±5.5% body weight, P=0.030) and the change in normal walking speed at week 16 (0.11±0.03 m/s vs 0.05±0.02 m/s, P=0.038) were significantly greater in the GCQID group than in the placebo group. Further subgroup analysis based on Kellgren-Lawrence (K-L) grade showed that normal walking speed at week 16 (1.36±0.05 m/s vs 1.21±0.02 m/s, P<0.05) was significantly greater in the GCQID group than in the placebo group in subjects with K-L grade I. No adverse effect of treatment was identified in the safety assessment. In subjects with knee pain, GCQID supplementation was effective for relieving knee pain and improving locomotor functions.

Pain affects more than one third of cancer patients in the early stages of their disease, dramatically rising above 70% in the advanced stages. Numerous studies have been conducted in the pursuit of cancer pain relief, yet the prevalence of pain persists. This article focuses on a pain management program, developed by a performance improvement team, which addressed the inadequacies of current pain management. Performance improvement activities are described through the process of assessment, planning, implementation, and evaluation of the pain management program. This pain management program is uniquely derived from a unit core value that all staff is responsible and accountable for pain management.

The objective of this study was to develop and pilot test a chronic pain empowerment and self-management platform, derived from acceptance and commitment therapy, in a pain specialty setting. A controlled, sequential, nonrandomized study design was used to accommodate intervention development and to test the efficacy of the PainTracker Self-Manager (PTSM) intervention (Web-based educational modules and outcome tracking combined with tailored patient coaching sessions and provider guidance). Generalized estimating equations evaluated changes over time (baseline, 3 months, 6 months) in pain self-efficacy (primary outcome), chronic pain acceptance (activity engagement and pain willingness), perceived efficacy in patient-provider interactions, pain intensity and interference, and overall satisfaction with pain treatment (secondary outcomes) between intervention (n = 48) and usual care control groups (n = 51). The full study sample (N = 99) showed greater improvements over time (significant Group × Time interactions) in pain self-efficacy and satisfaction with pain treatment. Among study completers (n = 82), greater improvement in activity engagement as well as pain intensity and interference were also observed. These preliminary findings support the efficacy of the PTSM intervention in a pain specialty setting. Further research is needed to refine and expand the PTSM intervention and to test it in a randomized trial in primary care settings. We developed a Web-based patient empowerment platform that combined acceptance and commitment therapy-based educational modules and tailored coaching sessions with longitudinal tracking of treatments and patient-reported outcomes, named PTSM. Pilot controlled trial results provide preliminary support for its efficacy in improving pain self-efficacy, activity engagement, pain intensity and interference, and satisfaction with pain treatment.

Postherpetic neuralgia (PHN) interferes with patients' quality of life, and disturbed sleep is a prevalent complaint. Pain-associated sleep interference in turn enhances pain and/or reduces pain tolerance. Therefore, reducing sleep interference by pain, in addition to pain control, may improve patient care. To address this notion, we characterized relationships among changes in pain intensity, sleep interference, and overall impression of improvement in PHN patients treated with gastroretentive gabapentin (G-GR). Patients with PHN (n = 556) received G-GR 1,800 mg once-daily in two phase 3 and one phase 4 study. Visual Analog Scale (VAS) and Brief Pain Inventory (BPI) were completed at baseline and the end of study. Patients' Global Impression of Change (PGIC) was completed at the end of study. Regression analyses examined relationships between VAS, BPI sleep interference by pain, and PGIC. At the end of treatment, 53.7 and 63.2 % of patients reported a ≥ 30 % reduction in VAS and BPI pain-associated sleep interference (BPISI) respectively; 46.3 % reported feeling "Much" or "Very Much" improved on the PGIC. There were positive correlations between the percent reductions in VAS and BPISI; both correlated with PGIC improvements. Percent changes in VAS and BPISI were significant (p < 0.0001 and p = 0.0082, respectively), and were independent predictors of feeling "Much" or "Very Much" improved on the PGIC. Reductions in pain intensity and in BPISI were correlated, and both also correlated with overall impression of improvement for patients with PHN treated with G-GR. Both pain relief and improvement BPISI independently predicted improvement in PGIC. For optimal patient care, clinicians should consider reducing the impact of pain on quality of sleep as well as overall pain reduction.

(i) To compare knowledge and compliance with good clinical practices regarding control of postoperative pain among nurses employed at hospitals with and without a "Hospital without Pain" certificate, (ii) to identify the determinants of nurses' knowledge and (iii) to define barriers to effective control of postoperative pain. Only a slight improvement in postoperative pain control has been observed recently, if any. Implementation of good clinical practices in the control of postoperative pain requires involvement of nurses. A cross-sectional study. The study included 257 nurses from hospitals with a "Hospital without Pain" certificate and 243 nurses from noncertified hospitals, with mean job seniority of 17.6 ± 9.6 years. All respondents answered 26 questions regarding postoperative pain control-related issues. Based on the answers, overall scores were calculated for (i) nurses' knowledge, (ii) compliance with good clinical practices and (iii) barriers to effective control of postoperative pain. Nurses from the certified hospitals presented with significantly higher levels of knowledge and compliance with good clinical practices and identified significantly more barriers to effective control of postoperative pain. Apart from certification of a hospital, better knowledge of postoperative pain control was determined by higher education, participation in postgraduate training programmes and other relevant courses, self-education from medical journals, employment at paediatric ward or intensive care unit. The most commonly reported barriers to effective control of pain included too low doses of painkillers prescribed by physicians and inability to modify the protocol of pain treatment by the nurse. Control of postoperative pain can be improved by enrolling nurses in various forms of continuous training and by providing them with greater autonomy in administering painkillers to surgical patients. Better quality of care offered to patients with postoperative pain

To compare the efficiency of transcutaneous electrical nerve stimulation (TENS) with those of exercise and acetaminophen for the treatment of pregnancy-related low back pain (LBP) during the third trimester of pregnancy. This prospective study included 79 subjects (≥32 gestational weeks) with visual analog scale (VAS) pain scores ≥5. Participants were divided randomly into a control group (n = 21) and three treatment groups [exercise (n = 19); acetaminophen (n = 19); TENS (n = 20)]. The VAS and the Roland-Morris disability questionnaire (RMDQ) were completed before and 3 weeks after treatment to assess the impact of pain on daily activities. During the study period, pain intensity increased in 57% of participants in the control group, whereas pain decreased in 95% of participants in the exercise group and in all participants in the acetaminophen and TENS groups. Post-treatment VAS and RMDQ values were significantly lower in the treatment groups (p < 0.001). VAS and RMDQ scores indicated a significantly greater degree of pain relief in the TENS group than in the exercise and acetaminophen groups (p < 0.001). No adverse effect of TENS application on pregnant women was observed during the study. TENS is an effective and safe treatment modality for LBP during pregnancy. TENS improved LBP more effectively than did exercise and acetaminophen. Copyright © 2012 S. Karger AG, Basel.

This study examined the effect of a theoretically grounded, tailored education-coaching intervention to help patients more effectively discuss their pain-related questions, concerns, and preferences with physicians. Grounded in social-cognitive and communication theory, a tailored education-coaching (TEC) intervention was developed to help patients learn pain management and communication skills. In a RCT, 148 cancer patients agreed to have their consultations audio-recorded and were assigned to the intervention or a control group. The recordings were used to code for patients' questions, acts of assertiveness, and expressed concerns and to rate the quality of physicians' communication. Patients in the TEC group discussed their pain concerns more than did patients in the control group. More active patients also had more baseline pain and interacted with physicians using participatory decision-making. Ratings of physicians' information about pain were higher when patients talked more about their pain concerns. The study demonstrates the efficacy of a theoretically grounded, coaching intervention to help cancer patients talk about pain control. Coaching interventions can be effective resources for helping cancer patients communicate about their pain concerns if they are theoretically grounded, can be integrated within clinical routines, and lead to improve health outcomes.

Postoperative pain control after total knee arthroplasty (TKA) remains a great challenge. The management of pain in the immediate postoperative period is one of the most critical aspects to allow speedier rehabilitation and reduce the risk of postoperative complications. Recently, periarticular infiltration anesthesia has become popular, but the outcome is controversial. Some studies have shown transient effects, "rebound pain", or no effectiveness in pain control. Continuous intra-articular infusion technique has been introduced to improve these transient effects, but more clinical studies are needed. Furthermore, the potential risk of early periprosthetic joint infection is causing concerning. We plan to compare continuous intra-articular infusion anesthesia with epidural infusion anesthesia after TKA to assess the effectiveness of this technique in reducing pain, in improving postoperative function, and to look at the evidence for risk of early infection. This trial is a randomized, controlled study. Patients (n = 214) will be randomized into two groups: to receive continuous intra-articular infusion anesthesia (group C); and epidural infusion anesthesia (group E). For the first 3 postoperative days, pain at rest, active range of motion (A-ROM), rescue analgesia and side effects will be recorded. At 3-month and 6-month follow-up, A-ROM, C-reactive protein, erythrocyte sedimentation rate, and synovial fluid cell count and culture will be analyzed. The results from this study will provide clinical evidence on the efficacy of a continuous intra-articular infusion technique in reducing pain, postoperative functional improvement and safety. It will be the first randomized controlled trial to investigate infection risk with local anesthesia after TKA. ClinicalTrials.gov identifier: ChiCTR-TRC-13003999.

Knee joint pain and reduced quadriceps strength are cardinal symptoms in many knee pathologies. In people with painful knee pathologies, quadriceps exercise reduces pain, improves physical function, and increases muscle strength. A general assumption is that pain compromises muscle function and thus may prevent effective rehabilitation. This study evaluated the effects of experimental knee joint pain during quadriceps strength training on muscle strength gain in healthy individuals. Twenty-seven healthy untrained volunteers participated in a randomized controlled trial of quadriceps strengthening (3 times per week for 8 weeks). Participants were randomized to perform resistance training either during pain induced by injections of painful hypertonic saline (pain group, n = 13) or during a nonpainful control condition with injection of isotonic saline (control group, n = 14) into the infrapatellar fat pad. The primary outcome measure was change in maximal isokinetic muscle strength in knee extension/flexion (60, 120, and 180 degrees/second). The group who exercised with pain had a significantly larger improvement in isokinetic muscle strength at all angular velocities of knee extension compared to the control group. In knee flexion there were improvements in isokinetic muscle strength in both groups with no between-group differences. Experimental knee joint pain improved the training-induced gain in muscle strength following 8 weeks of quadriceps training. It remains to be studied whether knee joint pain has a positive effect on strength gain in patients with knee pathology. Copyright © 2012 by the American College of Rheumatology.

According to literature, virtual reality was found to reduce pain and kinesiophobia in patients with chronic pain. The purpose of the study was to investigate short-term effect of the virtual reality on pain, function, and kinesiophobia in patients with subacute and chronic non-specific low-back pain METHODS: This randomised controlled study in which 44 patients were randomly assigned to the traditional physiotherapy (control group, 22 subjects) or virtual walking integrated physiotherapy (experimental group, 22 subjects). Before and after treatment, Visual Analog Scale (VAS), TAMPA Kinesiophobia Scale (TKS), Oswestry Disability Index (ODI), Nottingham Health Profile (NHP), Timed-up and go Test (TUG), 6-Minute Walk Test (6MWT), and Single-Leg Balance Test were assessed. The interaction effect between group and time was assessed by using repeated-measures analysis of covariance. After treatment, both groups showed improvement in all parameters. However, VAS, TKS, TUG, and 6MWT scores showed significant differences in favor of the experimental group. Virtual walking integrated physiotherapy reduces pain and kinesiophobia, and improved function in patients with subacute and chronic non-specific low-back pain in short term.

Pain management in hospitalized patients remains a priority area for improvement; effective strategies for consensus development are needed to prioritize interventions. To identify challenges, barriers, and perspectives of healthcare providers in managing pain among hospitalized patients. Qualitative and quantitative group consensus using a brainstorming technique for quality improvement-the nominal group technique (NGT). One medical, 1 medical-surgical, and 1 surgical hospital unit at a large academic medical center. Nurses, resident physicians, patient care technicians, and unit clerks. Responses and ranking to the NGT question: "What causes uncontrolled pain in your unit?" Twenty-seven health workers generated a total of 94 ideas. The ideas perceived contributing to a suboptimal pain control were grouped as system factors (timeliness, n = 18 ideas; communication, n = 11; pain assessment, n = 8), human factors (knowledge and experience, n = 16; provider bias, n = 8; patient factors, n = 19), and interface of system and human factors (standardization, n = 14). Knowledge, timeliness, provider bias, and patient factors were the top ranked themes. Knowledge and timeliness are considered main priorities to improve pain control. NGT is an efficient tool for identifying general and context-specific priority areas for quality improvement; teams of healthcare providers should consider using NGT to address their own challenges and barriers.

Use of low level of continuous heat as an adjunct to physical therapy improves knee pain recovery and the compliance for home exercise in patients with chronic knee pain: a randomized controlled trial. J Strength Cond Res 30(11): 3107-3115, 2016-This study examined if the use of low level continuous heat (LLCH) wraps at home between physical therapy sessions at a clinic resulted in better therapy outcomes in patients with chronic knee pain. Fifty individuals with chronic nonspecific knee pain was randomly allocated to 2 groups: the LLCH group and the placebo group. All subjects underwent 1 hour of conventional physical therapy twice per week for 2 weeks at the outpatient clinic and they were asked to accomplish 1 hour of therapeutic exercise at home each day between sessions. The LLCH group applied LLCH knee wraps for 6 hours at home before home exercise while placebo group took a placebo ibuprofen. (This was done since placebo heat is impossible to use since subjects would notice that the wraps were cold) Before, during, and after intervention, pain intensity, active range of motion of the knee (AROM), knee strength, and home exercise compliance were measured. The LLCH group showed pain attenuation after 2 weeks of therapy sessions (p ≤ 0.05). AROM and strength of the knee significantly improved over time compared to the placebo group. Home exercise compliance was significantly higher in the LLCH group than placebo group (p ≤ 0.05). These results indicated that the use of LLCH as an adjunct to conventional physical therapy for chronic knee pain significantly improved pain attenuation and recovery of strength and movement in patients with chronic knee pain.

Controlled trial of high-concentration capsaicin patch for treatment of painful HIV neuropathy.

HIV-associated distal sensory polyneuropathy (HIV-DSP) is a painful condition with limited effective treatment. Capsaicin desensitizes cutaneous nociceptors resulting in reduced pain. We report a placebo-controlled study of a high-concentration capsaicin dermal patch (NGX-4010) for the treatment of painful HIV-DSP. This double-blind multicenter study randomized 307 patients with painful HIV-DSP to receive NGX-4010 or control, a low-concentration capsaicin patch. After application of a topical anesthetic, NGX-4010 or control was applied once for 30, 60, or 90 minutes to painful areas on the feet. The primary efficacy endpoint was percent change in Numeric Pain Rating Scale (NPRS) from baseline in mean "average pain for past 24 hours" scores from weeks 2 to 12. A single NGX-4010 application resulted in a mean pain reduction of 22.8% during weeks 2 to 12 as compared to a 10.7% reduction for controls (p = 0.0026). Following a transient treatment-related pain increase, pain was reduced; significant improvement was apparent by week 2 and continued throughout the controlled 12-week observation period. Mean pain reductions in the NGX-4010 30-, 60- and 90-minute groups were 27.7%, 15.9%, and 24.7% (p = 0.0007, 0.287, and 0.0046 vs control). One third of NGX-4010-treated patients reported >or=30% pain decrease from baseline as compared to 18% of controls (p = 0.0092). Self-limited, mild-to-moderate local skin reactions were commonly observed. A single NGX-4010 application was safe and provided at least 12 weeks of pain reduction in patients with HIV-associated distal sensory polyneuropathy. These results suggest that NGX-4010 could provide a promising new treatment for painful HIV neuropathy.

Culp, William C., E-mail: culpwilliamc@uams.edu; McCowan, Timothy C.; DeValdenebro, Miguel

Background and Purpose. Percutaneous transhepatic biliary drainage remains a painful procedure in many cases despite the routine use of large amounts of intravenous sedation. We present a feasibility study of thoracic paravertebral blocks in an effort to reduce pain during and following the procedure and reduce requirements for intravenous sedation. Methods. Ten consecutive patients undergoing biliary drainage procedures received fluoroscopically guided paravertebral blocks and then had supplemental intravenous sedation as required to maintain patient comfort. Levels T8-T9 and T9-T10 on the right were targeted with 10-20 ml of 0.5% bupivacaine. Sedation requirements and pain levels were recorded. Results. Ten biliarymore » drainage procedures in 8 patients were performed for malignancy in 8 cases and for stones in 2. The mean midazolam use was 1.13 mg IV, and the mean fentanyl requirement was 60.0 {mu}g IV in the block patients. Two episodes of hypotension, which responded promptly to volume replacement, may have been related to the block. No serious complications were encountered. The mean pain score when traversing the chest wall, liver capsule, and upon entering the bile ducts was 0.1 on a scale of 0 to 10, with 1 patient reporting a pain level of 1 and 9 reporting 0. The mean peak pain score, encountered when manipulating at the common bile duct level or when addressing stones there, was 5.4 and ranged from 0 to 10. Conclusions. Thoracic paravertebral block with intravenous sedation supplementation appears to be a feasible method of pain control during biliary interventions.« less

Background: Neonatal pain management guidelines have been released; however, there is insufficient systematic institutional support for the adoption of evidence-based pain management in Japan. Purpose: To evaluate the impact of a collaborative quality improvement program on the implementation of pain management improvements in Japanese neonatal intensive care units (NICUs). Methods: Seven Japanese level III NICUs participated in a neonatal pain management quality improvement program based on an Institute for Healthcare Improvement collaborative model. The NICUs developed evidence-based practice points for pain management and implemented these over a 12-month period. Changes were introduced through a series of Plan-Do-Study-Act cycles, and throughout the process, pain management quality indicators were tracked as performance measures. Jonckheere's trend test and the Cochran-Armitage test for trend were used to examine the changes in quality indicator implementations over time (baseline, 3 months, 6 months, and 12 months). Findings: Baseline pain management data from the 7 sites revealed substantial opportunities for improvement of pain management, and testing changes in the NICU setting resulted in measurable improvements in pain management. During the intervention phase, all participating sites introduced new pain assessment tools, and all sites developed electronic medical record forms to capture pain score, interventions, and infant responses to interventions. Implications for Practice: The use of collaborative quality improvement techniques played a key role in improving pain management in the NICUs. Implications for Research: Collaborative improvement programs provide an attractive strategy for solving evidence-practice gaps in the NICU setting. PMID:28114148

Mounting evidence supports the use of face-to-face pain neuroscience education for the treatment of chronic pain patients. This study aimed at examining whether written education about pain neuroscience improves illness perceptions, catastrophizing, and health status in patients with fibromyalgia. A double-blind, multicenter randomized controlled clinical trial with 6-month follow-up was conducted. Patients with FM (n = 114) that consented to participate were randomly allocated to receive either written pain neuroscience education or written relaxation training. Written pain neuroscience education comprised of a booklet with pain neuroscience education plus a telephone call to clarify any difficulties; the relaxation group received a booklet with relaxation education and a telephone call. The revised illness perception questionnaire, Pain Catastrophizing Scale, and fibromyalgia impact questionnaire were used as outcome measures. Both patients and assessors were blinded. Repeated-measures analyses with last observation carried forward principle were performed. Cohen's d effect sizes (ES) were calculated for all within-group changes and between-group differences. The results reveal that written pain neuroscience education does not change the impact of FM on daily life, catastrophizing, or perceived symptoms of patients with FM. Compared with written relaxation training, written pain neuroscience education improved beliefs in a chronic timeline of FM (P = 0.03; ES = 0.50), but it does not impact upon other domains of illness perceptions. Compared with written relaxation training, written pain neuroscience education slightly improved illness perceptions of patients with FM, but it did not impart clinically meaningful effects on pain, catastrophizing, or the impact of FM on daily life. Face-to-face sessions of pain neuroscience education are required to change inappropriate cognitions and perceived health in patients with FM. © 2013 World Institute of Pain.

Background The aim of this study was to investigate the ability of a glucosamine-containing supplement to improve locomotor functions in subjects with knee pain. Methods A randomized, double-blind, placebo-controlled, parallel-group comparative study was conducted for 16 weeks in 100 Japanese subjects (age, 51.8±0.8 years) with knee pain. Subjects were randomly assigned to one of the two supplements containing 1) 1,200 mg of glucosamine hydrochloride, 60 mg of chondroitin sulfate, 45 mg of type II collagen peptides, 90 mg of quercetin glycosides, 10 mg of imidazole peptides, and 5 μg of vitamin D per day (GCQID group, n=50) or 2) a placebo (placebo group, n=50). Japanese Knee Osteoarthritis Measure, visual analog scale score, normal walking speed, and knee-extensor strength were measured to evaluate the effects of the supplement on knee-joint functions and locomotor functions. Results In subjects eligible for efficacy assessment, there was no significant group × time interaction, and there were improvements in knee-joint functions and locomotor functions in both groups, but there was no significant difference between the groups. In subjects with mild-to-severe knee pain at baseline, knee-extensor strength at week 8 (104.6±5.0% body weight vs 92.3±5.5% body weight, P=0.030) and the change in normal walking speed at week 16 (0.11±0.03 m/s vs 0.05±0.02 m/s, P=0.038) were significantly greater in the GCQID group than in the placebo group. Further subgroup analysis based on Kellgren–Lawrence (K–L) grade showed that normal walking speed at week 16 (1.36±0.05 m/s vs 1.21±0.02 m/s, P<0.05) was significantly greater in the GCQID group than in the placebo group in subjects with K–L grade I. No adverse effect of treatment was identified in the safety assessment. Conclusion In subjects with knee pain, GCQID supplementation was effective for relieving knee pain and improving locomotor functions. PMID:26604721

Background Chronic neuropathic pain affects 1%–2% of the adult population and is often refractory to standard pharmacologic treatment. Patients with chronic pain have reported using smoked cannabis to relieve pain, improve sleep and improve mood. Methods Adults with post-traumatic or postsurgical neuropathic pain were randomly assigned to receive cannabis at four potencies (0%, 2.5%, 6% and 9.4% tetrahydrocannabinol) over four 14-day periods in a crossover trial. Participants inhaled a single 25-mg dose through a pipe three times daily for the first five days in each cycle, followed by a nine-day washout period. Daily average pain intensity was measured using an 11-point numeric rating scale. We recorded effects on mood, sleep and quality of life, as well as adverse events. Results We recruited 23 participants (mean age 45.4 [standard deviation 12.3] years, 12 women [52%]), of whom 21 completed the trial. The average daily pain intensity, measured on the 11-point numeric rating scale, was lower on the prespecified primary contrast of 9.4% v. 0% tetrahydrocannabinol (5.4 v. 6.1, respectively; difference = 0.7, 95% confidence interval [CI] 0.02–1.4). Preparations with intermediate potency yielded intermediate but nonsignificant degrees of relief. Participants receiving 9.4% tetrahydrocannabinol reported improved ability to fall asleep (easier, p = 0.001; faster, p < 0.001; more drowsy, p = 0.003) and improved quality of sleep (less wakefulness, p = 0.01) relative to 0% tetrahydrocannabinol. We found no differences in mood or quality of life. The most common drug-related adverse events during the period when participants received 9.4% tetrahydrocannabinol were headache, dry eyes, burning sensation in areas of neuropathic pain, dizziness, numbness and cough. Conclusion A single inhalation of 25 mg of 9.4% tetrahydrocannabinol herbal cannabis three times daily for five days reduced the intensity of pain, improved sleep and was well tolerated.

Intrathecal drug delivery is known to be effective in alleviating cancer pain in patients for whom the conventional World Health Organization approach has proved insufficient. A multidisciplinary interventional cancer pain service was established in the West of Scotland in 2008 with the aim of providing a safe and effective intrathecal drug delivery service for patients with difficult-to-control cancer pain. The aim of the intrathecal drug delivery service is to improve pain scores as evaluated by pain scores before and after insertion of an intrathecal drug delivery device. Pain is monitored before and after intrathecal drug delivery implantation using the Brief Pain Inventory. Following implantation, pumps are refilled fortnightly and repeat Brief Pain Inventory assessments are undertaken. This prospective case series analyses change in Brief Pain Inventory domains for patients who had an intrathecal drug delivery implanted using a paired sample t-test. Data are presented from 2008-2013 for 22 patients receiving an intrathecal drug delivery system who experienced an immediate improvement in their pain that was both clinically and statistically significant. One week after insertion, the average pain score on the Brief Pain Inventory fell from 6.8 (pre-intrathecal drug delivery) to 3.0 (post-intrathecal drug delivery). Improvement in pain scores was sustained over a 6-month period. Evaluation of results of this case series shows that with the appropriate use of intrathecal drug delivery systems, patients with difficult-to-control cancer pain can benefit from effective pain relief for many months. © The Author(s) 2015.

When appropriate, to assess the influence of treatment characteristics (i.e. technique, dosage), methodological quality, symptom duration and subtypes of neck disorder on treatment outcomes. Review authors searched the following computerised databases to November 2014 to identify additional studies: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We also searched ClinicalTrials.gov, checked references, searched citations and contacted study authors to find relevant studies. We updated this search in June 2015, but these results have not yet been incorporated. Randomised controlled trials (RCTs) undertaken to assess whether manipulation or mobilisation improves clinical outcomes for adults with acute/subacute/chronic neck pain. Two review authors independently selected studies, abstracted data, assessed risk of bias and applied Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methods (very low, low, moderate, high quality). We calculated pooled risk ratios (RRs) and standardised mean differences (SMDs). We included 51 trials (2920 participants, 18 trials of manipulation/mobilisation versus control; 34 trials of manipulation/mobilisation versus another treatment, 1 trial had two comparisons).

Randomized controlled trial. To investigate the effectiveness and costs of a mini-intervention, provided in addition to the usual care, and the incremental effect of a work site visit for patients with subacute disabling low back pain. There is lack of data on cost-effectiveness of brief interventions for patients with prolonged low back pain. A total of 164 patients with subacute low back pain were randomized to a mini-intervention group (A), a work site visit group (B), or a usual care group (C). Groups A (n = 56) and B (n = 51) underwent one assessment by a physician plus a physiotherapist. Group B received a work site visit in addition. Group C served as controls (n = 57) and was treated in municipal primary health care. All patients received a leaflet on back pain. Pain, disability, specific and generic health-related quality of life, satisfaction with care, days on sick leave, and use and costs of health care consumption were measured at 3-, 6-, and 12-month follow-ups. During follow-up, fewer subjects had daily pain in Groups A and B than in Group C (Group A Group C, = 0.002; Group B Group C, = 0.030). In Group A, pain was less bothersome (Group A Group C, = 0.032) and interfered less with daily life (Group A Group C, = 0.040) than among controls. Average days on sick leave were 19 in Group A, 28 in Group B, and 41 in Group C (Group A Group C, = 0.019). Treatment satisfaction was better in the intervention groups than among the controls, and costs were lowest in the mini-intervention group. Mini-intervention reduced daily back pain symptoms and sickness absence, improved adaptation to pain and patient satisfaction among patients with subacute low back pain, without increasing health care costs. A work site visit did not increase effectiveness.

Background This study evaluated the benefits and safety of a multimodal pain control protocol, which included a periarticular injection of local anesthetics, in patients undergoing total hip arthroplasty. Methods Between March 2006 and March 2007, 60 patients undergoing unilateral total hip arthroplasty were randomized to undergo either a multimodal pain control protocol or a conventional pain control protocol. The following parameters were compared: the preoperative and postoperative visual analogue scales (VAS), hospital stay, operative time, postoperative rehabilitation, additional painkiller consumption, and complication rates. Results There was no difference between the groups in terms of diagnosis, age, gender, and BMI. Although both groups had similar VAS scores in the preoperative period and on the fifth postoperative day, there was a significant difference between the groups over the four-day period after surgery. There were no differences in the hospital stay, operative time, additional painkiller consumption, or complication rate between the groups. The average time for comfortable crutch ambulation was 2.8 days in the multimodal pain control protocol group and 5.3 days in the control group. Conclusions The multimodal pain control protocol can significantly reduce the level of postoperative pain and improve patients' satisfaction, with no apparent risks, after total hip arthroplasty.

BACKGROUND: The underassessment and undertreatment of pain in residents of long-term care (LTC) facilities has been well documented. Gaps in staff knowledge and inaccurate beliefs have been identified as contributors. OBJECTIVES: To investigate the effectiveness of an expert-based continuing education program in pain assessment/management for LTC staff. METHODS: Participants included 131 LTC staff members who were randomly assigned to either an interactive pain education (PE) program, which addressed gaps in knowledge such as medication management, or an interactive control program consisting of general dementia education without a specific clinical focus. Participants attended three sessions, each lasting 3 h, and completed measures of pain-related knowledge and attitudes/beliefs before, immediately after and two weeks following the program. Focus groups were conducted with a subset of participants to gauge perception of the training program and barriers to implementing pain-related strategies. RESULTS: Analysis using ANOVA revealed that PE participants demonstrated larger gains compared with control participants with regard to pain knowledge and pain beliefs. Barriers to implementing pain-related strategies certainly exist. Nonetheless, qualitative analyses demonstrated that PE participants reported that they overcame many of these barriers and used pain management strategies four times more frequently than control participants. CONCLUSIONS: Contrary to previous research, the present study found that the interactive PE program was effective in changing pain beliefs and improving knowledge. Continuing PE in LTC has the potential to address knowledge gaps among front-line LTC providers. PMID:23457681

The cause of pain in a phantom limb after partial or complete deafferentation is an important problem. A popular but increasingly controversial theory is that it results from maladaptive reorganization of the sensorimotor cortex, suggesting that experimental induction of further reorganization should affect the pain, especially if it results in functional restoration. Here we use a brain–machine interface (BMI) based on real-time magnetoencephalography signals to reconstruct affected hand movements with a robotic hand. BMI training induces significant plasticity in the sensorimotor cortex, manifested as improved discriminability of movement information and enhanced prosthetic control. Contrary to our expectation that functional restoration would reduce pain, the BMI training with the phantom hand intensifies the pain. In contrast, BMI training designed to dissociate the prosthetic and phantom hands actually reduces pain. These results reveal a functional relevance between sensorimotor cortical plasticity and pain, and may provide a novel treatment with BMI neurofeedback. PMID:27807349

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

To examine the effect of a multicomponent intervention on pain and function after orthopedic surgery. Controlled prospective propensity score-matched clinical trial. New York City acute rehabilitation hospital. Two hundred forty-nine patients admitted to rehabilitation after hip fracture repair (n=51) or hip (n=64) or knee (n=134) arthroplasty. Pain assessment at rest and with physical therapy (PT) by staff using numeric rating scales (1 to 5). Physician protocols for standing analgesia and preemptive analgesia before PT were implemented on the intervention unit. Control unit patients received usual care. Pain, analgesic prescribing, gait speed, transfer time, and percentage of PT sessions completed during admission. Pain and difficulty walking at 6, 12, 18, and 24 weeks after discharge. In multivariable analyses intervention patients were significantly more likely than controls to report no or mild pain at rest (66% vs 49%, P=.004) and with PT (52% vs 38%, P=.02) on average for the first 7 days of rehabilitation, had faster 8-foot-walk times on Days 4 (9.3 seconds vs 13.2 seconds, P=.02) and 7 (6.9 vs 9.2 seconds, P=.02), received more analgesia (23.6 vs 15.6 mg of morphine sulfate equivalents per day, P<.001), were more likely to receive standing orders for analgesia (98% vs 48%, P<.001), and had significantly shorter lengths of stay (10.1 vs 11.3 days, P=.005). At 6 months, intervention patients were less likely than controls to report moderate to severe pain with walking (4% vs 15%, P=.02) and that pain did not interfere with walking (7% vs 18%, P=.004) and were less likely to be taking analgesics (35% vs 51%, P=.03). The intervention improved postoperative pain, reduced chronic pain, and improved function.

Practical strategies are needed to improve pain awareness among aged care staff and promote a systematic approach to pain identification using evidence-based tools. The purpose of this study was to evaluate a pain identification tool for use by nursing and nonprofessional staff in residential aged care facilities (RACFs). A controlled pretest-posttest intervention design was conducted in two RACFs in Brisbane, Australia. Completed surveys were returned by 216 staff and 74 residents at baseline and 218 staff and 94 residents at 3-month follow-up. Chart audits were conducted on 308 residents at baseline and 328 at follow-up. Groups were compared on: (1) staff knowledge and attitudes regarding pain, perceived confidence and skills for pain assessment, and perceived quality of pain management; (2) frequency of pain assessments and use of pain interventions; and (3) residents' perceptions of the quality of pain management. Both groups had high knowledge scores and reported high levels of confidence, skills, and perceived quality of pain management at baseline and follow-up. The intervention group showed significant improvement in routine pain assessment and use of nonpharmacological pain interventions. However, due to unexpected changes in control group conditions, both groups increased episodic pain assessment. Overall, staff believed the intervention was clinically useful and fostered a team approach to pain assessment. We found the introduction of pain identification resources with implementation strategies to support frontline staff was partially effective in improving staff and resident outcomes. Nonetheless, our findings confirm the need for change and importance of translational pain research in RACFs. Copyright © 2016 American Society for Pain Management Nursing. Published by Elsevier Inc.

Objectives: This study aimed to determine the effects of participatory workplace improvement (PWI) -based provision of ergonomic training and ergonomic action checklists (ACLs) to on-site managers on workplace improvement activities for low back pain (LBP). Methods: A randomized controlled trial (RCT) was conducted at a manufacturing company in Japan. Teams entered in the study were randomly assigned to a control and an intervention group. A total of three interventional training sessions on methods of ergonomics were provided to on-site managers in the intervention group, with 1-month intervals between sessions. Ergonomic ACLs were provided at the same time. After completion of the training sessions, each team then provided a report of improvements each month for the next 10 months. Two people in charge of safety and health chose two major objectives of the implemented activities from the five categories. The reported number of improvements was analyzed using a Poisson regression model. Results: In the intervention group, although the incident rate ratio (IRR) of PWIs in countermeasures for the LBP category was significantly elevated after the training sessions, the IRR of improvements decreased over time during the 10-month follow-up period. No significant difference was observed in the IRR of total PWIs in either the control or intervention group. Conclusions: PWI-based provision of ergonomic training sessions and ergonomics ACLs to on-site managers was shown to be effective for workplace improvement activities targeted at LBP. However, because the effects decrease over time, efforts should be made to maintain the effects through regular interventions. PMID:28320978

Previous studies have indicated that neck pain patients feel increased symptoms following upper limb activities, and altered axioscapular muscle function has been proposed as a contributing factor. Pain sensitivity and muscle activity, during arm movements, were assessed in neck pain patients and controls. Patients with ongoing insidious-onset neck pain (IONP, N = 16) and whiplash-associated disorders (WAD, N = 9) were included along with sex- and age-matched controls (N = 25). Six series of repeated arm abductions were performed during electromyographic (EMG) recordings from eight bilateral muscles. The first and last three series were separated by 8 min and 42 s, respectively. Each series consisted of three slow and three fast movements. Pressure pain thresholds (PPTs) were recorded bilaterally from neck, head and arm at baseline, after the third and sixth movement series. Pain intensity was recorded on an electronic visual analogue scale (VAS). Larger pain areas and higher VAS scores were found in patients compared with controls (p < 0.001), and in patients, the VAS scores increased in the course of movements (p < 0.02). PPTs were lower in patients compared with controls at all sites (p < 0.03), and these decreased during arm movements in the IONP group (p < 0.03), while increasing at head and neck sites in controls (p < 0.04). During the slow movements, increasing serratus anterior EMG activity was found in the series with short breaks in-between for the WAD group compared with IONP and controls (p < 0.001). Axioscapular movement caused different responses in pain sensitivity and muscle activity between neck pain patient groups compared with controls. Neck pain patients report increased symptoms following upper limb activities. This study shows that repeated arm movements caused differentiated responses in pain sensitivity and muscle activity between subgroups of neck pain patient and asymptomatic controls. Such findings may be of great

Most children experience pain in hospitals; and their parents report dissatisfaction with how well pain was managed. Engaging patients and families in the development and evaluation of pain treatment plans may improve perceptions of pain management and hospital experiences. The aim of this performance improvement project was to engage patients and families to address hospitalized pediatric patients' pain using interactive patient care technology. The goal was to stimulate conversations about pain management expectations and perceptions of treatment plan effectiveness among patients, parents, and health care teams. Plan-Do-Study-Act was used to design, develop, test, and pilot new workflows to integrate the interactive patient care technology system with the automated medication dispensing system and document actions from both systems into the electronic health record. The pediatric surgical unit and hematology/oncology unit of a free-standing, university-affiliated, urban children's hospital were selected to pilot this performance improvement project because of the high prevalence of pain from surgeries and hematologic and oncologic diseases, treatments, and invasive procedures. Documentation of pain assessments, nonpharmacologic interventions, and evaluation of treatment effectiveness increased. The proportion of positive family satisfaction responses for pain management significantly increased from fiscal year 2014 to fiscal year 2016 (p = .006). By leveraging interactive patient care technologies, patients and families were engaged to take an active role in pain treatment plans and evaluation of treatment outcomes. Improved active communication and partnership with patients and families can effectively change organizational culture to be more sensitive to patients' pain and patients' and families' hospital experiences.

Improving joint pain and function in osteoarthritis.

Owens, Claire; Conaghan, Philip G

2016-12-01

Osteoarthritis has become a major chronic pain condition. It affects more than 10% of adults and accounts for almost 10% of health service resources. The impact of osteoarthritis is amplified by underuse of effective muscle strengthening exercises and a focus on often less effective and poorly tolerated analgesic therapies. Although traditionally considered to be primarily a disease of cartilage, there is now ample evidence that typical clinical osteoarthritis involves multiple tissue pathologies. Increased BMI is associated with a higher incidence of knee osteoarthritis. Anatomical abnormalities such as valgus alignment or previous joint trauma including meniscectomy, anterior cruciate ligament rupture and fracture through the joint are also associated with increased incidence of osteoarthritis. Pain is the main presenting symptom. However, we still have a poor understanding of the causes of pain in osteoarthritis. In patients aged 45 or over the diagnosis should be made clinically without investigations if the patient has activity-related joint pain in addition to early morning joint stiffness lasting less than 30 minutes. Muscle strengthening and aerobic exercise have been shown to improve joint pain and function. Weight loss not only improves joint pain and function but has a myriad of other health benefits, reducing the incidence of lifestyle associated diseases such as cardiovascular disease and type 2 diabetes, and mechanical stress on the joints.

Lumbopelvic stabilization training (LPST) may provide therapeutic benefits on pain modulation in chronic nonspecific low back pain conditions. This study aimed to examine the effects of LPST on pain threshold and pain intensity in comparison with the passive automated cycling intervention and control intervention among patients with chronic nonspecific low back pain. A within-subject, repeated-measures, crossover randomized controlled design was conducted among 25 participants (7 males and 18 females) with chronic nonspecific low back pain. All the participants received 3 different types of experimental interventions, which included LPST, the passive automated cycling intervention, and the control intervention randomly, with 48 hours between the sessions. The pressure pain threshold (PPT), hot-cold pain threshold, and pain intensity were estimated before and after the interventions. Repeated-measures analysis of variance showed that LPST provided therapeutic effects as it improved the PPT beyond the placebo and control interventions (P < 0.01). The pain intensity under the LPST condition was significantly better than that under the passive automated cycling intervention and controlled intervention (P < 0.001). Heat pain threshold under the LPST condition also showed a significant trend of improvement beyond the control (P < 0.05), but no significant effects on cold pain threshold were evident. Lumbopelvic stabilization training may provide therapeutic effects by inducing pain modulation through an improvement in the pain threshold and reduction in pain intensity. LPST may be considered as part of the management programs for treatment of chronic low back pain. © 2017 World Institute of Pain.

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

Despite evidence that many nursing home residents' pain is poorly managed, reasons for this poor management remain unanswered. The aim of this study was to determine if specific order sets related to pain assessment would improve pain management in nursing home (NH) residents. Outcomes included observed nurse pain assessment queries and resident reports of pain. The pretest/post-test study was performed in a 240-bed for-profit nursing home in the mid-southern region of the United States and participants were 43 nursing home residents capable of self-consent. Medical chart abstraction was performed during a 2-week (14-day) period before the implementation of specific order sets for pain assessment (intervention) and a 2-week (14-day) period after the intervention. Trained research assistants observed medication administration passes and performed participant interviews after each medication pass. One month after intervention implementation, 1 additional day of observations was conducted to determine data reliability. Nurses were observed to ask residents about pain more frequently, and nurses continued to ask about pain at higher rates 1 month after the intervention was discontinued. The proportion of residents who reported pain also significantly increased in response to increased nurse queries (e.g., "Do you have any pain right now?"), which underscores the importance of nurses directly asking residents about pain. Notably 70% of this long-stay NH population only told the nurses about their pain symptoms when asked directly. Findings uncover that using specific pain order sets seems to improve the detection of pain, which should be a routine part of nursing assessment.

Most people with dementia develop neuropsychiatric symptoms (NPSs), which are distressing for their carers. Untreated pain may increase the prevalence and severity of NPSs and thereby staff burden. We investigated the association between NPSs and the impact of individual pain treatment on distress in nursing home staff. Nursing home (NH) units were cluster-randomized to an intervention group (33 NH units; n = 175) or control group (27 NH units; n = 177). Patients in the intervention group received individual pain treatment for eight weeks, followed by a four-week washout period; control groups received care as usual. Staff informants (n = 138) used the Neuropsychiatric Inventory-NH version (including caregiver distress) as primary outcome to assess their own distress. Other outcomes were pain (Mobilization-Observation-Behavior-Intensity-Dementia-2 Pain Scale) and cognitive functioning (Mini-Mental State Examination). Using hierarchical regression analysis, all NPS items at baseline were associated with staff distress (P < 0.01) apart from euphoria; agitation had the largest contribution (β = 0.24). Using mixed models, we found significantly lower staff distress in the intervention group compared to the control group. Moreover, we also found significantly reduced distress in the control group, and there were still effects in both groups throughout the washout period. Individual pain treatment reduced staff distress in the intervention group compared to control group especially in regard to agitation-related symptoms and apathy. Furthermore, our results indicated a multifactorial model of staff distress, in which enhanced knowledge and understanding of NPSs and pain in people with advanced dementia may play an important role.

Acute ankle sprains are common and activity limiting injuries, and topical diclofenac gel has proven efficacy in alleviating pain and restoring function. This trial aimed to compare a topical natural agent, Traumeel with topical diclofenac gel (1%) in the management of acute ankle sprain. This prospective, multicentre, randomised, blinded, active-control and non-inferiority study involved 449 physically active adults sustaining unilateral grade 1 or 2 ankle sprain within the past 24 h. Participants were randomised to receive 2 g of Traumeel ointment (T-O) (n = 152) or Traumeel gel (T-G) (n = 150) or diclofenac gel (D-G) (n = 147), administered topically to the ankle three times a day for 14 days, with 6-weeks follow up. Day 7 median percentage reductions in Visual Analogue Scale pain score were 60.6%, 71.1% and 68.9% for the T-O, T-G and D-G groups, respectively.

Here we aim to present an accessible review of the pharmacological targets for pain management, and succinctly discuss the newest trends in pain therapy. A key task for current pain pharmacotherapy is the identification of receptors and channels orchestrating nociception. Notwithstanding peripheral alterations in the receptors and channels following pathophysiological events, the modulatory mechanisms in the central nervous system are also fundamental to the regulation of pain perception. Bridging preclinical and clinical studies of peripheral and central components of pain modulation, we present the different types of pain and relate these to pharmacological interventions. We firstly highlight the roles of several peripheral nociceptors, such as NGF, CGRP, sodium channels, and TRP-family channels that may become novel targets for therapies. In the central nervous system, the roles of calcium channels and gabapentinoids as well as NMDA receptors in generating excitability are covered including ideas on central sensitization. We then turn to central modulatory systems and discuss opioids and monoamines. We aim to explain the importance of central sensitization and the dialogue of the spinal circuits with the brain descending modulatory controls before discussing a mechanism-based effectiveness of antidepressants in pain therapy and their potential to modulate the descending controls. Emphasizing the roles of conditioned pain modulation and its animal's equivalent, diffuse noxious inhibitory controls, we discuss these unique descending modulations as a potential tool for understanding mechanisms in patients suffering from pain. Mechanism-based therapy is the key to picking the correct treatments and recent clinical studies using sensory symptoms of patients as surrogates for underlying mechanisms can be used to subgroup patients and reveal actions of drugs that may be lost when studying heterogenous groups of patients.

To explore and improve the quality of continuous epidural analgesia for pain relief using Statistical Process Control tools. Measuring the quality of pain management interventions is complex. Intermittent audits do not accurately capture the results of quality improvement initiatives. The failure rate for one intervention, epidural analgesia, is approximately 30% in everyday practice, so it is an important area for improvement. Continuous measurement and analysis are required to understand the multiple factors involved in providing effective pain relief. Process control and quality improvement Routine prospectively acquired data collection started in 2006. Patients were asked about their pain and side effects of treatment. Statistical Process Control methods were applied for continuous data analysis. A multidisciplinary group worked together to identify reasons for variation in the data and instigated ideas for improvement. The key measure for improvement was a reduction in the percentage of patients with an epidural in severe pain. The baseline control charts illustrated the recorded variation in the rate of several processes and outcomes for 293 surgical patients. The mean visual analogue pain score (VNRS) was four. There was no special cause variation when data were stratified by surgeons, clinical area or patients who had experienced pain before surgery. Fifty-seven per cent of patients were hypotensive on the first day after surgery. We were able to demonstrate a significant improvement in the failure rate of epidurals as the project continued with quality improvement interventions. Statistical Process Control is a useful tool for measuring and improving the quality of pain management. The applications of Statistical Process Control methods offer the potential to learn more about the process of change and outcomes in an Acute Pain Service both locally and nationally. We have been able to develop measures for improvement and benchmarking in routine care that

OBJECTIVE Pain control is an important clinical consideration and quality-of-care metric. No studies have examined postoperative pain control following transsphenoidal surgery for pituitary lesions. The study goals were to 1) report postoperative pain scores following transsphenoidal surgery, 2) determine if multimodal opioid-minimizing pain regimens yielded satisfactory postoperative pain control, and 3) determine if intravenous (IV) ibuprofen improved postoperative pain scores and reduced opioid use compared with placebo. METHODS This study was a single-center, randomized, double-blinded, placebo-controlled intervention trial involving adult patients with planned transsphenoidal surgery for pituitary tumors randomized into 2 groups. Group 1 patients were treated with scheduled IV ibuprofen, scheduled oral acetaminophen, and rescue opioids. Group 2 patients were treated with IV placebo, scheduled oral acetaminophen, and rescue opioids. The primary end point was patient pain scores (visual analog scale [VAS], rated 0-10) for 48 hours after surgery. The secondary end point was opioid use as estimated by oral morphine equivalents (OMEs). RESULTS Of 136 patients screened, 62 were enrolled (28 in Group 1, 34 in Group 2). The study was terminated early because the primary and secondary end points were reached. Baseline characteristics between groups were well matched except for age (Group 1, 59.3 ± 14.4 years; Group 2, 49.8 ± 16.2 years; p = 0.02). Mean VAS pain scores were significantly different, with a 43% reduction in Group 1 (1.7 ± 2.2) compared with Group 2 (3.0 ± 2.8; p < 0.0001). Opioid use was significantly different, with a 58% reduction in Group 1 (26.3 ± 28.7 mg OME) compared with Group 2 (62.5 ± 63.8 mg OME; p < 0.0001). CONCLUSIONS Multimodal opioid-minimizing pain-management protocols resulted in acceptable pain control following transsphenoidal surgery. IV ibuprofen resulted in significantly improved pain scores and significantly decreased opioid

Stroke patients can experience a variety of pain. Many stroke patients have co-morbidities such as osteoporosis, arthritis or diabetes causing diabetic neuropathy. As well as pain from other long term conditions, stroke patients can experience central post-stroke pain, headaches, and musculoskeletal issues such as hypertonia, contractures, spasticity, and subluxations. These stroke patients can also have communication difficulties in the form of expressive dysphasia and/or global aphasia. Communication difficulties can result in these patients not expressing their pain and therefore not having it assessed, leading to inadequate pain relief that could impact their rehabilitation and recovery. By implementing an observational measurement of pain such as the Abbey pain scale, patients with communication difficulties can have their pain assessed and recorded. Initially 30% of patients on the acute stroke ward did not have their pain assessed and adequately recorded and 15% of patients had inadequate pain relief. The patient was assessed if they were in pain and therefore not receiving adequate pain relief by measuring their pain on the Abbey pain scale. After introducing the Abbey pain scale and creating a nurse advocate, an improvement was shown such that only 5% of patients did not have their pain recorded and all had adequate pain relief.

The objective of this study was to determine the relative efficacy of irradiation using a device containing a far-infrared emitting ceramic powder (cFIR) for the management of chronic myofascial neck pain compared with a control treatment. This was a randomized, double-blind, placebo-controlled pilot study. The study comprised 48 patients with chronic, myofascial neck pain. Patients were randomly assigned to the experimental group or the control (sham-treatment) group. The patients in the experimental group wore a cFIR neck device for 1 week, and the control group wore an inert neck device for 1 week. Quantitative measurements based on a visual analogue scale (VAS) scoring of pain, a sleep quality assessment, pressure-pain threshold (PPT) testing, muscle tone and compliance analysis, and skin temperature analysis were obtained. Both the experimental and control groups demonstrated significant improvement in pain scores. However, no statistically significant difference in the pain scores was observed between the experimental and control groups. Significant decreases in muscle stiffness in the upper regions of the trapezius muscles were reported in the experimental group after 1 week of treatment. Short-term treatment using the cFIR neck device partly reduced muscle stiffness. Although the differences in the VAS and PPT scores for the experimental and control groups were not statistically significant, the improvement in muscle stiffness in the experimental group warrants further investigation of the long-term effects of cFIR treatment for pain management.

Cesarean delivery is a common surgery in the United States, with 1.3 million performed during 2009. 1 Obstetricians must balance the growing concern with opioid abuse, dependence, and side effects with optimal postoperative pain control. Intravenous acetaminophen may represent an additional method to decrease the reliance on opioid medications and improve postoperative pain following cesarean delivery. The objective of the study was to determine whether the administration of intravenous acetaminophen following routine scheduled cesarean delivery would decrease the need for narcotic medications to control postoperative pain. This was an institutional review board-approved, double-blind, placebo-controlled, randomized trial, registered on clinicaltrials.gov (number 02046382). Women scheduled to undergo cesarean delivery with regional anesthesia at term were recruited. All perioperative and postpartum care was standardized via study order sets. Study patients were given all medications in a standardized manner receiving either acetaminophen 1000 mg intravenously or 100 mL saline (placebo) every 8 hours for 48 hours for a total of 6 doses. The pharmacy prepared intravenous acetaminophen and saline in identical administration bags labeled study drug to ensure blinding. The initial dose of study drug was given within 60 minutes of skin incision. Quantity of breakthrough and scheduled analgesic medications and self-reported pain levels on the Faces Pain Scale (0-10) before and after study drug administration were collected. Patient demographics were extracted from the chart. Power calculation determined that 45 patients per arm were required to detect a 30% reduction in postcesarean narcotic requirement with 80% power and a significance level of P = .05. A total of 133 patients were consented for the study. Twenty-nine were excluded and 104 patients completed the study: 57 received intravenous acetaminophen and 47 received placebo. There were no differences in baseline

Pain is common and can be debilitating in childhood. Theoretical models propose that attention to pain plays a key role in pain outcomes, however, very little research has investigated this in youth. This study examined how anxiety-related variables and attention control interacted to predict children's attention to pain cues using eye-tracking methodology, and their pain tolerance on the cold pressor test (CPT). Children aged 8-17 years had their eye-gaze tracked whilst they viewed photographs of other children displaying painful facial expressions during the CPT, before completing the CPT themselves. Children also completed self-report measures of anxiety and attention control. Findings indicated that anxiety and attention control did not impact children's initial fixations on pain or neutral faces, but did impact how long they dwelled on pain versus neutral faces. For children reporting low levels of attention control, higher anxiety was associated with less dwell time on pain faces as opposed to neutral faces, and the opposite pattern was observed for children with high attention control. Anxiety and attention control also interacted to predict pain outcomes. For children with low attention control, increasing anxiety was associated with anticipating more pain and tolerating pain for less time. This is the first study to examine children's attention to pain cues using eye-tracking technology in the context of a salient painful experience. Data suggest that attention control is an important moderator of anxiety on multiple outcomes relevant to young people's pain experiences. This study uses eye tracking to study attention to pain cues in children. Attention control is an important moderator of anxiety on attention bias to pain and tolerance of cold pressor pain in youth. © 2016 European Pain Federation - EFIC®.

Alendronate is more effective than elcatonin in improving pain and quality of life in postmenopausal women with osteoporosis.

A randomized controlled trial was performed to compare the short-term effects of alendronate (ALN) and ECT on pain and quality of life (QOL) in postmenopausal women with osteoporosis. Back pain and QOL [Short-Form Health Survey (SF-8)] significantly improved at 1, 3, and 6 months in both groups, with greater improvements in the ALN group than in the ECT group. These results suggested that ALN reduced back pain and improved QOL more markedly than ECT in postmenopausal osteoporotic women with back pain. Intramuscular ECT is known to reduce pain via the central nervous system. A multicenter randomized controlled trial was performed to compare the short-term effects of ALN and ECT on pain and QOL in postmenopausal women with osteoporosis. One hundred and 94 postmenopausal osteoporotic women with back pain (mean age 79.8 years, range 60-96 years) were randomly divided into two groups: the ALN group (35 mg weekly) and the ECT group (intramuscular 20 units a week). The duration of the study was 6 months. The trial was completed in 97 (100%) women of the ALN group and 96 (99.0%) women of the ECT group. Urinary levels of cross-linked N-terminal telopeptide of type I collagen (NTX), serum alkaline phosphatase (ALP), face scale score (FSS, back pain), and SF-8 (QOL) were monitored. Urinary NTX levels significantly decreased at 3 months in the ALN group, but not in the ECT group. Serum ALP levels significantly decreased at 6 months in the both groups, with a greater reduction in the ALN group. The FSS and SF-8 significantly improved at 1, 3, and 6 months in both groups, with greater improvements in the ALN group than in the ECT group. ALN suppressed bone turnover, reduced back pain, and improved QOL more markedly than ECT in postmenopausal osteoporotic women with back pain.

Controllability and hippocampal activation during pain expectation in fibromyalgia syndrome.

To examine the role of perceived control in pain perception, fibromyalgia patients and healthy controls participated in a reaction time experiment under different conditions of pain controllability. No significant differences between groups were found in pain intensity and unpleasantness ratings. However, during the expectation of uncontrollable pain, patients compared to controls showed higher hippocampal activation. In addition, hippocampal activity during the pain expectation period predicted activation of the posterior cingulate cortex (PCC), precuneus and hippocampus during pain stimulation in fibromyalgia patients. The increased activation of the hippocampus during pain expectation and subsequent activation of the PCC/precuneus during the lack of control phase points towards an influence of pain perception through heightening of alertness and anxiety responses to pain in fibromyalgia patients.

Competing effects of pain and fear of pain on postural control in low back pain?

A cross-sectional, observational study. To determine whether pain and fear of pain have competing effects on postural sway in patients with low back pain (LBP). Competing effects of pain and pain-related fear on postural control can be proposed as the likely explanation for inconsistent results regarding postural sway in the LBP literature. We hypothesized that although pain might increase postural sway, fear of pain might reduce sway through an increased cognitive effort or increased cocontraction to restrict body movement. The cognitive strategy would be less effective under dual-task conditions and the cocontraction strategy was expected to be less effective when standing on a narrow base of support surface. Postural sway was measured in combined conditions of base of support (full and narrow) and cognitive loading (single and dual tasks) in 3 experimental groups with current LBP, recent LBP, and no LBP. Sway amplitude, path length, mean power frequency, and sample entropy were extracted from center-of-pressure data. The current-LBP group and recent-LBP group reported significantly different levels of pain, but similar levels of pain catastrophizing and kinesiophobia. The current-LBP group tended to display larger sway amplitudes in the anteroposterior direction compared with the other 2 groups. Mean power frequency values in mediolateral direction were lower in patients with the current LBP compared with recent LBP. Smaller sample entropy was found in the current-LBP group than the other groups in most experimental conditions, particularly when standing on a narrow base of support. Alterations of postural sway are mostly mediated by pain but not pain-related fear. LBP tends to increase sway amplitude, which seems to be counteracted by increased effort invested in postural control leading to decreased frequency and increased regularity of sway particularly under increased task demands.

A multisite, randomized, controlled clinical effectiveness trial was conducted for osteoarthritis patients with chronic pain of the knee or hip. Adult health nurse practitioners provided a 10-session intervention, pain coping skills training (PCST), in patients’ doctors’ offices (N = 129 patients); the control group received usual care (N = 127 patients). Primary outcomes assessed at baseline, posttreatment, 6-month follow-up, and 12-month follow-up were: pain intensity, physical functioning, psychological distress, self-efficacy, catastrophizing, use of coping strategies, and quality of life. Secondary measures included fatigue, social functioning, health satisfaction, and use of pain medication. Methods favoring external validity, consistent with pragmatic, effectiveness research, were utilized. Primary ITT and secondary per-protocol analyses were conducted. Attrition was within the expected range: 11% at posttreatment and 29% at 12-month follow-up; rates did not differ between groups. Omnibus ITT analyses across all assessment points indicated significant improvement for the PCST group compared with the control group for pain intensity, physical functioning, psychological distress, use of pain coping strategies, and self-efficacy, as well as fatigue, satisfaction with health, and reduced use of pain medication. Treatment effects were robust to covariates (demographics and clinical sites). Trends in the outcomes across the assessments were examined. All outcomes, except for self-efficacy, were maintained through the 12-month follow-up; effects for self-efficacy degraded over time. Per-protocol analyses did not yield greater effect sizes. Comparisons of PCST patients who were more vs less treatment adherent suggested greater effectiveness for patients with high adherence. Results support the effectiveness of nurse practitioner delivery of PCST for chronic osteoarthritis pain. PMID:24865795

Postoperative pain control after arthroscopic rotator cuff repair.

Arthroscopic rotator cuff repair (ARCR) can provide excellent clinical results for patients who fail to respond to conservative management of symptomatic rotator cuff tears. ARCR, however, can be associated with severe postoperative pain and discomfort that requires adequate analgesia. As ARCR continues to shift toward being performed as an outpatient procedure, it is incumbent on physicians and ambulatory surgical centers to provide appropriate pain relief with minimal side effects to ensure rapid recovery and safe discharge. Although intravenous and oral opioids are the cornerstone of pain management after orthopedic procedures, they are associated with drowsiness, nausea, vomiting, and increased length of hospital stay. As health care reimbursements continue to become more intimately focused on quality, patient satisfaction, and minimizing of complications, the need for adequate pain control with minimal complications will continue to be a principal focus for providers and institutions alike. We present a review of alternative modalities for pain relief after ARCR, including cryotherapy, intralesional anesthesia, nerve blockade, indwelling continuous nerve block catheters, and multimodal anesthesia. In choosing among these modalities, physicians should consider patient- and system-based factors to allow the efficient delivery of analgesia that optimizes recovery and improves patient satisfaction.

Pain Control in the Presence of Drug Addiction.

Vadivelu, Nalini; Lumermann, Leandro; Zhu, Richard; Kodumudi, Gopal; Elhassan, Amir O; Kaye, Alan David

2016-05-01

Drug addiction is present in a significant proportion of the population in the USA and worldwide. Drug addiction can occur with the abuse of many types of substances including cocaine, marijuana, stimulants, alcohol, opioids, and tranquilizers. There is a high likelihood that clinicians will encounter patients with substance abuse disorders on a regular basis with the prevalence of the use of illicit substances and the high rate of abuse of prescription drugs. The use of abuse deterrent formulations of prescription opioid agents, pill counts, and urine drug abuse screenings are all useful strategies. Optimum pain management of patients with addiction in the outpatient and inpatient setting is essential to minimize pain states. Careful selection of medications and appropriate oversight, including drug agreements, can reduce drug-induced impairments, including sleep deficits and diminished physical, social, and sexual functioning. This review, therefore, discusses the prevalence of illicit and prescription drug addiction, the challenges of achieving optimum pain control, and the therapeutic approaches to be considered in this challenging population. More research is warranted to develop improved therapies and routes of treatments for optimum pain relief and to prevent the development of central sensitization, chronic pain, and impaired physical and social functioning in patients with drug addiction.

To investigate the effect of Kinesio taping application in acute non-specific low back pain. A randomized controlled clinical trial. Physical Medicine and Rehabilitation Clinic. A total of 109 patients with acute low back pain were randomized into either Kinesio taping (n = 54) or control (n = 55) groups. The intervention group was treated with information and reassurance plus Kinesio taping, while the control group received merely information and reassurance. All participants were allowed to use as-needed doses of paracetamol. Kinesio tape was applied to the most painful area of the low back for a total of 12 days. Worst pain and disability were assessed at baseline, after the 12-day intervention, and at four weeks follow-up. During the first 12 days, participants filled in a pain diary consisting of a numeric rating scale and recorded the number of paracetamol tablets consumed daily. Disability was assessed with the Oswestry Disability Index. After 12 days of intervention, pain intensity and the Oswestry Disability Index improved significantly in both groups; the improvements were significantly superior in the Kinesio taping group (p = 0.003, p = 0.011). The Kinesio taping group reached pain control earlier (sixth day vs. 12th day) and consumed less paracetamol. At the fourth week, although pain intensity was significantly more reduced in the Kinesio taping group (p = 0.015), there were no differences with regard to disability. Kinesio taping provided significant improvements in pain and disability; thus, it can be used as a complementary method in acute non-specific low back pain. © The Author(s) 2015.

Improving access to adequate pain management in Taiwan.

PubMed

Scholten, Willem

2015-06-01

There is a global crisis in access to pain management in the world. WHO estimates that 4.65 billion people live in countries where medical opioid consumption is near to zero. For 2010, WHO considered a per capita consumption of 216.7 mg morphine equivalents adequate, while Taiwan had a per capita consumption of 0.05 mg morphine equivalents in 2007. In Asia, the use of opioids is sensitive because of the Opium Wars in the 19th century and for this reason, the focus of controlled substances policies has been on the prevention of diversion and dependence. However, an optimal public health outcome requires that also the beneficial aspects of these substances are acknowledged. Therefore, WHO recommends a policy based on the Principle of Balance: ensuring access for medical and scientific purposes while preventing diversion, harmful use and dependence. Furthermore, international law requires that countries ensure access to opioid analgesics for medical and scientific purposes. There is evidence that opioid analgesics for chronic pain are not associated with a major risk for developing dependence. Barriers for access can be classified in the categories of overly restrictive laws and regulations; insufficient medical training on pain management and problems related to assessment of medical needs; attitudes like an excessive fear for dependence or diversion; and economic and logistical problems. The GOPI project found many examples of such barriers in Asia. Access to opioid medicines in Taiwan can be improved by analysing the national situation and drafting a plan. The WHO policy guidelines Ensuring Balance in National Policies on Controlled Substances can be helpful for achieving this purpose, as well as international guidelines for pain treatment.

The frequency and characteristics of chronic widespread pain in general practice: a case-control study.

Rohrbeck, Jens; Jordan, Kelvin; Croft, Peter

2007-02-01

Chronic widespread pain is common in the community but is not often diagnosed in primary care. One explanation may be that widespread pain is presented and treated in primary care as multiple episodes of regional pain. To determine whether patients who consult with multiple regional pain syndromes have characteristics consistent with chronic widespread pain. Case-control study. One general practice in North Staffordshire, UK. Participants were 148 cases who consulted regularly with different musculoskeletal pains over 5 years, and 524 controls who had not consulted for musculoskeletal pain during the same period. A postal questionnaire survey and medical record review were undertaken. Cases with musculoskeletal pain reported more health problems and higher levels of fatigue than controls, and significantly worse general health and greater sleep disturbance (odds ratios 3.3. and 3.1, respectively). They generally reported more severe symptoms and consulted more frequently for a range of problems, but this was not explained by a general propensity to consult. Patients who consult in primary care with multiple regional pain syndromes have similar characteristics to those associated with chronic widespread pain and fibromyalgia. Recognising the need for general approaches to pain management, rather than treating each syndrome as a regional problem of pain, may improve the outcome in such patients.

To determine the intensity of pain in operated patients using a visual analogue scale and identify variables associated with lack of pain control in three cities in Colombia. A cross-sectional study in patients over the age of 18 years, between January 1 st and September 30 th 2014, in 3 clinics in Colombia. The intensity of postoperative pain using a visual analogue scale at 24hours after surgery was recorded. Socio-demographic, clinical and pharmacological variables were taken into account. SPSS 22.0 was used for the analysis. 460 patients were evaluated, mean age 47.6±17.4 years, and 63.3% were female. The mean pain level was 23.8±17.4mm, with 91 (19.8% of patients) with moderate or greater pain (i.e., lack of pain control). Tramadol was the most used analgesic, followed by dipyrone and diclofenac. 53.0% were treated with monotherapy. Compliance with the dosing regimen of the first analgesic (OR: 0.53; 95% CI: 0.294 to .988; p=.046) was statistically significantly associated with a decreased risk of poorly controlled pain. Pain intensity and the proportion of patients with uncontrolled pain at 24hours after surgery show better results than other studies previously published in the country. There must be insistence on the administration of analgesia within a suitable interval in order to improve pain control. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Do photographic images of pain improve communication during pain consultations?

Padfield, Deborah; Zakrzewska, Joanna M; Williams, Amanda C de C

2015-01-01

Visual images may facilitate the communication of pain during consultations. To assess whether photographic images of pain enrich the content and⁄or process of pain consultation by comparing patients' and clinicians' ratings of the consultation experience. Photographic images of pain previously co-created by patients with a photographer were provided to new patients attending pain clinic consultations. Seventeen patients selected and used images that best expressed their pain and were compared with 21 patients who were not shown images. Ten clinicians conducted assessments in each condition. After consultation, patients and clinicians completed ratings of aspects of communication and, when images were used, how they influenced the consultation. The majority of both patients and clinicians reported that images enhanced the consultation. Ratings of communication were generally high, with no differences between those with and without images (with the exception of confidence in treatment plan, which was rated more highly in the image group). However, patients' and clinicians' ratings of communication were inversely related only in consultations with images. Methodological shortcomings may underlie the present findings of no difference. It is also possible that using images raised patients' and clinicians' expectations and encouraged emotional disclosure, in response to which clinicians were dissatisfied with their performance. Using images in clinical encounters did not have a negative impact on the consultation, nor did it improve communication or satisfaction. These findings will inform future analysis of behaviour in the video-recorded consultations.

Chronic low back pain (CLBP) in older adults may be disabling and therapeutically challenging, largely because of the inefficacy and/or morbidity associated with traditional pain treatment. We conducted a randomized controlled trial in 200 men and women ≥ age 65 with CLBP to evaluate the efficacy of percutaneous electrical nerve stimulation (PENS) with and without general conditioning and aerobic exercise (GCAE), for reducing pain and improving physical function. Participants were randomized to receive 1) PENS, 2) control-PENS (brief electrical stimulation to control for treatment expectancy), 3) PENS + GCAE, or 4) control-PENS + GCAE, twice a week for 6 weeks. All four groups experienced significantly reduced pain (range −2.3 to −4.1 on the McGill Pain Questionnaire short form), improved self-reported disability (range −2.1 to −3.0 on Roland scale) and improved gait velocity (0.04–0.07 m/sec), sustained at 6 months. The GCAE groups experienced significantly fewer fear avoidance beliefs immediately post-intervention and at 6 months than non-GCAE groups. There were no significant side effects. Since brief electrical stimulation (i.e., control-PENS) facilitated comparably reduced pain and improved function at 6 months as compared with PENS, the exact dose of electrical stimulation required for analgesia cannot be determined. GCAE was more effective than PENS alone in reducing fear avoidance beliefs, but not in reducing pain or improving physical function. PMID:18930352

There are reports suggesting that sensitivity to and tolerance of both clinical and experimental pain differ among ethnic groups. We examined self-rated pain score and morphine usage in 1034 women who underwent elective lower cesarian section (LSCS) for their deliveries. Data on pain scores and amount of total morphine use according to patient-controlled analgesia were collected every 4 hours. Overall, lowest pain scores were recorded 12 hours after surgery and highest at 24 hours. Morphine consumption was highest within the first 4 hours and lowest between 12 and 16 hours. There were statistically significant ethnic group differences in pain scores (P = 1.7 x 10(-7)) and morphine usage (P = 2.8 x 10(-15)) between ethnic groups, with Indians having the highest mean pain score and using the highest amount of morphine. The ethnic differences in pain score and morphine self-administration persisted after controlling for age, body mass index, and duration of operation. Our findings of highly significant ethnic group difference in self-reported pain level and the amount of analgesia self-administered may have implications on optimal management of acute postoperative pain. Inadequate management of pain after cesarian deliveries might affect the emotional well-being and physical recovery of patients and affect mother-child bonding.

In Parkinson's disease (PD), chronic pain is a common symptom which markedly affects the quality of life. Some physiological arguments proposed that Deep Brain Stimulation of the Subthalamic Nucleus (STN-DBS) could improve pain in PD. We investigated in 58 PD patients the effect of STN-DBS on pain using the short McGill Pain Questionnaire and other pain parameters such as the Bodily discomfort subscore of the Parkinson's disease Questionnaire 39 and the Unified Parkinson's Disease Rating Scale section II (UPDRS II) item 17. All pain scores were significantly improved 12 months after STN-DBS. This improvement was not correlated with motor improvement, depression scores or L-Dopa reduction. STN-DBS induced a substantial beneficial effect on pain in PD, independently of its motor effects and mood status of patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

To investigate the efficacy of shoe orthotics with and without chiropractic treatment for chronic low back pain compared with no treatment. Randomized controlled trial. Integrative medicine teaching clinic at a university. Adult subjects (N=225) with symptomatic low back pain of ≥3 months were recruited from a volunteer sample. Subjects were randomized into 1 of 3 treatment groups (shoe orthotic, plus, and waitlist groups). The shoe orthotic group received custom-made shoe orthotics. The plus group received custom-made orthotics plus chiropractic manipulation, hot or cold packs, and manual soft tissue massage. The waitlist group received no care. The primary outcome measures were change in perceived back pain (numerical pain rating scale) and functional health status (Oswestry Disability Index) after 6 weeks of study participation. Outcomes were also assessed after 12 weeks and then after an additional 3, 6, and 12 months. After 6 weeks, all 3 groups demonstrated significant within-group improvement in average back pain, but only the shoe orthotic and plus groups had significant within-group improvement in function. When compared with the waitlist group, the shoe orthotic group demonstrated significantly greater improvements in pain (P<.0001) and function (P=.0068). The addition of chiropractic to orthotics treatment demonstrated significantly greater improvements in function (P=.0278) when compared with orthotics alone, but no significant difference in pain (P=.3431). Group differences at 12 weeks and later were not significant. Six weeks of prescription shoe orthotics significantly improved back pain and dysfunction compared with no treatment. The addition of chiropractic care led to higher improvements in function. Copyright © 2017 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Fractures of the thoracolumbar spine can cause pain, long-term reductions in quality of life (QOL), and neural deficits. The aim of this study was to investigate the effects of methylene blue (MB) on preventing postoperative pain and improving QOL in patients with throracolumbar fractures undergoing posterior pedicle screw fixation. Fifty patients underwent standard posterior pedicular screw fixation for stabilization of the thoracolumbar fractures: 25 received 1ml of MB solution at a concentration of 0.5% and 25 received normal saline on the soft tissue around fusion site. Primary outcomes were the control of pain, evaluated at 48h, 2 and 6 months after surgery with the use of a visual analog scale (VAS), and the improvement of QOL, assessed 2 and 6 months postoperatively by means of Oswestry Disability Index (ODI) questionnaire. The mean VAS scores for pain were significantly lower in the MB group compared with the control group at 2 months (1.30±0.45 vs. 2.60±1.19, P<0.001) and 6 months (1.17±0.37 vs. 1.60±0.87; P=0.028) after treatment. At 2 months after the surgery, the mean ODI score was significantly lower in the MB-treated patients than the control group (20.4±10.92 vs. 34.8±15.11; P=0.001). The ODI score in the MB-treated patients was better than the control group at 6 months after the surgery (12.2±11.66 vs. 20.8±11.14; P=0.016). A single dose of MB on the soft tissue around fusion site shows promising results in terms of safety, reduction of postoperative pain, and functional results when compared with placebo 6 months after surgery.

In 2007, the Mater Children's Hospital Emergency Department participated in the Emergency Care Pain Management Initiative funded by the National Health and Medical Research Council National Institute of Clinical Studies (NHMRC-NICS). The findings of this NHMRC-NICS research across eleven paediatric emergency departments highlighted deficits in pain management of abdominal pain. Specifically pain assessment, timeliness of analgesia, and pain management guidelines were found to be lacking. In response to the NICS report local practice was reviewed and a pilot research project undertaken to develop a clinical guideline for the pain management of abdominal pain in children presenting to the emergency department. The guideline was developed by an expert panel and trialled using a pre and post intervention design. The results demonstrated improved compliance to assessment and documentation of pain scores and assimilation of the best practice principles recommended in the guideline. This project raised local awareness in the pain management of abdominal pain and provides baseline information for future improvement. The guideline has been trialled in the clinical setting of paediatric emergency and has the potential to improve pain management practices in children presenting to the emergency department with abdominal pain.

Dental infections are frequent and have recently been implicated as a possible risk factor for Alzheimer's disease (AD). Despite a lack of studies investigating orofacial pain in this patient group, dental conditions are known to be a potential cause of pain and to affect quality of life and disease progression. To evaluate oral status, mandibular function and orofacial pain in patients with mild AD versus healthy subjects matched for age and gender. Twenty-nine patients and 30 control subjects were evaluated. The protocol comprised a clinical questionnaire and dental exam, research diagnostic criteria for temporomandibular disorders, the McGill Pain Questionnaire, the decayed, missing, and filled teeth index, and included a full periodontal evaluation. AD signs and symptoms as well as associated factors were evaluated by a trained neurologist. A higher prevalence of orofacial pain (20.7%, p < 0.001), articular abnormalities in temporomandibular joints (p < 0.05), and periodontal infections (p = 0.002) was observed in the study group compared to the control group. Orofacial pain and periodontal infections were more frequent in patients with mild AD than in healthy subjects. Orofacial pain screening and dental and oral exams should be routinely performed in AD patients in order to identify pathological conditions that need treatment thus improving quality of life compromised due to dementia.

Medical treatment of cranio-cervical pain can be suboptimal in patients with internal carotid artery (ICA) dissection. We report the use of cervical sympathetic block for treatment of pain in two patients with ICA dissection. A 58-year-old man and a 43-year-old woman presented with severe cranio-cervical pain associated with left and right ICA dissection confirmed by magnetic resonance imaging and cerebral angiography. Due to suboptimal control of pain with medical treatment, cervical sympathetic block was performed under fluoroscopic guidance using 20 ml of bupivacaine injected lateral to the posterior aspect of sixth vertebral body in both patients. On self-reported pain scale, the 58-year-old man reported improvement in pain intensity from 8/10 pain to 0/10 within 1 h of blockade. The patient remained relatively pain free for the 24-h post blockade. Mild recurrence of pain was noted on Day 2. The 43-year-old woman reported improvement in pain intensity from 6/10 pain to 0/10 within 1 h of blockade. The patient remained pain free for five days with recurrence to previous intensity. Cervical sympathetic blockade in patients with ICA dissection may be an effective option in the event of suboptimal pain control with medical treatment; however, the technique may be limited due to relatively short duration of action.

Background. Multiple sclerosis (MS) is a chronic demyelinating neurological disease. Several studies have reported that complementary and alternative therapies can have positive effects against pain in these patients. Objective. The objective was to investigate the effectiveness of an Ai-Chi aquatic exercise program against pain and other symptoms in MS patients. Methods. In this randomized controlled trial, 73 MS patients were randomly assigned to an experimental or control group for a 20-week treatment program. The experimental group underwent 40 sessions of Ai-Chi exercise in swimming pool and the control group 40 sessions of abdominal breathing and contraction-relaxation exercises in therapy room. Outcome variables were pain, disability, spasm, depression, fatigue, and autonomy, which were assessed before the intervention and immediately and at 4 and 10 weeks after the last treatment session. Results. The experimental group showed a significant (P < 0.028) and clinically relevant decrease in pain intensity versus baseline, with an immediate posttreatment reduction in median visual analogue scale scores of 50% that was maintained for up to 10 weeks. Significant improvements were also observed in spasm, fatigue, disability, and autonomy. Conclusion. According to these findings, an Ai-Chi aquatic exercise program improves pain, spasms, disability, fatigue, depression, and autonomy in MS patients.

Shoulder pain is the third most common musculoskeletal problem and accounts for 5% of general practitioner consultations. Although many treatments are described, there is no consensus on optimal treatment and up to 40% of patients still have pain 12 months after initially seeking help for pain. Previously, the effect of transcutaneous pulsed radiofrequency treatment (TCPRFT) was evaluated in a retrospective audit that showed good pain relief for a mean 395 days and justified this randomized sham controlled trial. In this study, 51 patients entered into a randomized double-blinded, placebo controlled study of TCPRFT. Patients were assessed at 4 and 12 weeks by a blinded observer and compared with baseline. We observed sustained reductions in pain at night, pain with activity, and functional improvement at 4 and 12 weeks with active but not sham TCPRFT. The 25 subjects who received active treatment showed statistically significant reductions of 24/100 in pain at night and 20/100 of pain with activity at 4 weeks and 18/100 and 19/100, respectively, at 12 weeks from baseline. Statistically significant lower Brief Pain Inventory pain and function scores (4 and 12 weeks), improved pain self-efficacy (4 weeks), Oxford Shoulder scores (12 weeks), and internal rotation (12 weeks) were seen. Pain at both rest and shoulder elevation were not improved by active treatment. No complications were seen. This study of a simple, low risk, outpatient treatment confirms the findings of our earlier study of TCPRFT for knee pain and shoulder pain audit that transcutaneous pulsed radiofrequency treatment may help some people with painful shoulders. © 2013 The Authors Pain Practice © 2013 World Institute of Pain.

Challenge of improving postoperative pain management: case studies of three acute pain services in the UK National Health Service.

Previous national survey research has shown significant deficits in routine postoperative pain management in the UK. This study used an organizational change perspective to explore in detail the organizational challenges faced by three acute pain services in improving postoperative pain management. Case studies were conducted comprising documentary review and semi-structured interviews (71) with anaesthetists, surgeons, nurses, other health professionals, and managers working in and around three broadly typical acute pain services. Although the precise details differed to some degree, the three acute pain services all faced the same broad range of inter-related challenges identified in the organizational change literature (i.e. structural, political, cultural, educational, emotional, and physical/technological challenges). The services were largely isolated from wider organizational objectives and activities and struggled to engage other health professionals in improving postoperative pain management against a background of limited resources, turbulent organizational change, and inter- and intra-professional politics. Despite considerable efforts they struggled to address these challenges effectively. The literature on organizational change and quality improvement in health care suggests that it is only by addressing the multiple challenges in a comprehensive way across all levels of the organization and health-care system that sustained improvements in patient care can be secured. This helps to explain why the hard work and commitment of acute pain services over the years have not always resulted in significant improvements in routine postoperative pain management for all surgical patients. Using this literature and adopting a whole-organization quality improvement approach tailored to local circumstances may produce a step-change in the quality of routine postoperative pain management.

The objective of this study is to analyze the immediate effects on neck pain and active cervical range of motion after a single cervical high-velocity low-amplitude (HVLA) manipulation or a control mobilization procedure in mechanical neck pain subjects. In addition, we assessed the possible correlation between neck pain and neck mobility. Seventy patients with mechanical neck pain (25 males and 45 females, aged 20-55 years) participated in this study. The lateral gliding test was used to establish the presence of an intervertebral joint dysfunction at the C3 through C4 or C4 through C5 levels. Subjects were divided randomly into either an experimental group, which received an HVLA thrust, or a control group, which received a manual mobilization procedure. The outcome measures were active cervical range of motion and neck pain at rest assessed pretreatment and 5 minutes posttreatment by an assessor blinded to the treatment allocation of the patient. Intragroup and intergroup comparisons were made with parametric tests. Within-group effect sizes were calculated using Cohen's d coefficient. Within-group changes showed a significant improvement in neck pain at rest and mobility after application of the manipulation (P < .001). The control group also showed a significant improvement in neck pain at rest (P < .01), flexion (P < .01), extension (P < .05), and both lateral flexions (P < .01), but not in rotation. Pre-post effect sizes were large for all the outcomes in the experimental group (d > 1), but were small to medium in the control mobilization group (0.2 < d < 0.6). The intergroup comparison showed that the experimental group obtained a greater improvement than the control group in all the outcome measures (P < .001). Decreased neck pain and increased range of motion were negatively associated for all cervical motions: the greater the increase in neck mobility, the less the pain at rest. Our results suggest that a single cervical HVLA manipulation was more

Vertical Heterophoria and Postural Control in Nonspecific Chronic Low Back Pain

The purpose of this study was to test postural control during quiet standing in nonspecific chronic low back pain (LBP) subjects with vertical heterophoria (VH) before and after cancellation of VH; also to compare with healthy subjects with, and without VH. Fourteen subjects with LBP took part in this study. The postural performance was measured through the center of pressure displacements with a force platform while the subjects fixated on a target placed at either 40 or 200 cm, before and after VH cancellation with an appropriate prism. Their postural performance was compared to that of 14 healthy subjects with VH and 12 without VH (i.e. vertical orthophoria) studied previously in similar conditions. For LBP subjects, cancellation of VH with a prism improved postural performance. With respect to control subjects (with or without VH), the variance of speed of the center of pressure was higher, suggesting more energy was needed to stabilize their posture in quiet upright stance. Similarly to controls, LBP subjects showed higher postural sway when they were looking at a target at a far distance than at a close distance. The most important finding is that LBP subjects with VH can improve their performance after prism-cancellation of their VH. We suggest that VH reflects mild conflict between sensory and motor inputs involved in postural control i.e. a non optimal integration of the various signals. This could affect the performance of postural control and perhaps lead to pain. Nonspecific chronic back pain may results from such prolonged conflict. PMID:21479210

The use of therapy dogs has a positive effect on patients' pain level and satisfaction with hospital stay after total joint replacement. Surgeons are encouraged to inquire about the status of volunteer-based animal-assisted therapy programs in their hospital as this may provide a means to improve the immediate postoperative recovery for a select group of patients having total joint arthroplasty.

A randomized controlled trial of intensive neurophysiology education in chronic low back pain.

Cognitive-behavioral pain management programs typically achieve improvements in pain cognitions, disability, and physical performance. However, it is not known whether the neurophysiology education component of such programs contributes to these outcomes. In chronic low back pain patients, we investigated the effect of neurophysiology education on cognitions, disability, and physical performance. This study was a blinded randomized controlled trial. Individual education sessions on neurophysiology of pain (experimental group) and back anatomy and physiology (control group) were conducted by trained physical therapist educators. Cognitions were evaluated using the Survey of Pain Attitudes (revised) (SOPA(R)), and the Pain Catastrophizing Scale (PCS). Behavioral measures included the Roland Morris Disability Questionnaire (RMDQ), and 3 physical performance tasks; (1) straight leg raise (SLR), (2) forward bending range, and (3) an abdominal "drawing-in" task, which provides a measure of voluntary activation of the deep abdominal muscles. Methodological checks evaluated non-specific effects of intervention. There was a significant treatment effect on the SOPA(R), PCS, SLR, and forward bending. There was a statistically significant effect on RMDQ; however, the size of this effect was small and probably not clinically meaningful. Education about pain neurophysiology changes pain cognitions and physical performance but is insufficient by itself to obtain a change in perceived disability. The results suggest that pain neurophysiology education, but not back school type education, should be included in a wider pain management approach.

We investigated the function of parental attention to child pain in regulating parental distress and pain control behaviour when observing their child performing a painful (cold pressor) task (CPT); we also studied the moderating role of parental state anxiety. Participants were 62 schoolchildren and one of their parents. Parental attention towards or away from child pain (ie, attend to pain vs avoid pain) was experimentally manipulated during a viewing task pairing unfamiliar children's neutral and pain faces. Before and after the viewing task, parental distress regulation was assessed by heart rate (HR) and heart rate variability (HRV). In a subsequent phase, parents observed their own child perform a CPT task, allowing assessment of parental pain control behaviour (indexed by latency to stop their child's CPT performance) and parental distress, which was assessed via self-report before and after observation of child CPT performance. Eye tracking during the viewing task and self-reported attention to own child's pain confirmed successful attention manipulation. Further, findings indicated that the effect of attentional strategy on parental emotion regulation (indexed by HR, self-report) and pain control behaviour depended on parents' state anxiety. Specifically, whereas low anxious parents reported more distress and demonstrated more pain control behaviour in the Attend to Pain condition, high anxious parents reported more distress and showed more pain control behaviour in the Avoid Pain condition. This inverse pattern was likewise apparent in physiological distress indices (HR) in response to the initial viewing task. Theoretical/clinical implications and further research directions are discussed. Copyright © 2014 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.

Many women experience pain during hysterosalpingogram (HSG). This prospective, randomized, double-blinded, placebo-controlled study assessed whether the use of benzocaine spray during HSG is associated with reduced pain as compared with placebo. Thirty women presenting for HSG were enrolled and randomized to either benzocaine or saline spray. Treatment groups were similar in age, race, parity, pre-procedure oral analgesic use and history of dysmenorrhoea and/or chronic pelvic pain. Median change in pain score from baseline to procedure was 50.6mm (-7.4 to 98.8mm) in the benzocaine group and 70.4mm (19.8 to 100mm) in the placebo group. There was no difference between groups after adjusting for history of dysmenorrhoea. There was no difference in resolution of pain in benzocaine versus placebo groups at 5 min post procedure--median pain score difference -11.1 (-90.1 to 18.5) versus -37.0 (-100 to 1.2)--or at 30 min post procedure. Satisfaction scores did not differ by treatment and did not correlate with pain score during the procedure (rho=0.005). The use of benzocaine spray does not significantly improve pain relief during HSG nor does it hasten resolution of pain post HSG. Of interest, patient satisfaction was not correlated with pain. Many women experience pain during hysterosalpingogram (HSG), which is a test used to evaluate the uterine cavity and fallopian tube. We conducted a prospective, randomized, double-blinded, placebo-controlled study to assess whether the use of benzocaine spray during HSG is associated with reduced pain as compared with placebo. Thirty women presenting for HSG were enrolled and randomized to either benzocaine or saline spray. Treatment groups were similar in age, race, previous pregnancies, pre-procedure oral analgesic use and history of dysmenorrhoea (painful periods) and/or chronic pelvic pain. There was no difference in pain scores or resolution of pain between the two groups. Satisfaction scores did not differ by treatment group

To determine the feasibility, acceptability, and efficacy of a computer-based positive psychology intervention in individuals with a physical disability and chronic pain. Individuals with spinal cord injury, multiple sclerosis, neuromuscular disease, or postpolio syndrome and chronic pain were randomly assigned to a positive psychology or a control condition. Participants in the intervention group were instructed to practice 4 personalized positive psychology exercises. Participants in the control group were instructed to write about life details for 8 weeks. Participants completed online well-being and pain-related questionnaires at baseline, posttreatment, and at the 2.5-month follow-up, and rated treatment satisfaction at posttreatment. Ninety-six participants were randomized and 68 (70%) completed follow-up assessments. Participants in the positive psychology intervention group reported significant pretreatment to posttreatment improvements in pain intensity, pain control, pain catastrophizing, pain interference, life satisfaction, positive affect, and depression. Improvements in life satisfaction, depression, pain intensity, pain interference, and pain control were maintained to the 2.5-month follow-up. Participants in the control group reported significant pretreatment to posttreatment improvements in life satisfaction, and pretreatment to follow-up improvements in pain intensity and pain control. Significant between-group differences, favoring the treatment group, emerged for pretreatment to posttreatment improvements in pain intensity and pain control. Participants were similarly satisfied with both treatments. The results support the feasibility, acceptability, and potential efficacy of a computer-based positive psychology intervention for improving well-being and pain-related outcomes in individuals with physical disabilities and chronic pain, and indicate that a full trial of the intervention is warranted.

To assess the effectiveness of 12 weeks of Pilates practice on disability, pain and kinesiophobia in patients with chronic non-specific low back pain. This is a randomized controlled trial. This study was conducted in the university laboratory. A total of 64 participants with chronic non-specific low back pain were included. Participants were randomly allocated to intervention group consisted in Pilates intervention during 12 weeks ( n = 32) or control group who received no treatment ( n = 32). Disability, pain and kinesiophobia were assessed by Roland Morris Disability Questionnaire, visual analogue scale and Tampa Scale of Kinesiophobia, respectively. Measurements were performed at baseline, at 6 and 12 weeks after study completion. There were significant differences between groups with observed improvement in Pilates intervention group in all variables after treatment ( P < 0.001). Major changes on disability and kinesiophobia were observed at six weeks of intervention with no significant difference after 12 weeks ( P < 0.001). Mean changes of the intervention group compared with the control group were 4.00 (0.45) on the Roland Morris Disability Questionnaire and 5.50 (0.67) in the Tampa Scale of Kinesiophobia. Pain showed better results at six weeks with a slightly but statistically significant improvement at 12 weeks with Visual Analogue Scale scores of 2.40 (0.26) ( P < 0.001). Pilates intervention in patients with chronic non-specific low back pain is effective in the management of disability, pain and kinesiophobia.

To improve pain management practices, we developed an online interactive continuing education (CE) program for primary care providers (PCPs). This program follows the flow of clinical decision-making through simulated cases at critical pain treatment points along the pain treatment continuum. A randomized controlled trial was conducted to test the efficacy of this program. Participants were randomized to either the experimental condition or the control condition (online, text-based CE program). A total of 238 primary care providers were recruited through hospitals, professional newsletters, and pain conferences. Participants in both conditions reported significantly improved scores on knowledge (KNOW-PAIN 50), attitudes (CAOS), and pain practice behaviors (PPBS) scales over the four-month study. The experimental condition showed significantly greater change over time on the tamper-resistant formulations (TRFs) of opioids and dosing CAOS subscale compared with the control condition. Post hoc comparisons suggested that participants in the experimental condition were less likely to endorse use of opioid TRFs over time compared with the control condition. Exploratory analyses for potential moderators indicated a significant three-way interaction with time, condition, and discipline (i.e., physician vs other) for the impediments and concerns attitudes subscale and the early refill behaviors subscale. Post hoc comparisons indicated that physicians in the experimental condition exhibited the greatest change in attitudes and the nonphysicians exhibited the greatest change in reported behaviors in response to requests for early refills. Findings suggest online CE programs may positively impact PCPs' knowledge, attitudes, and pain practice behaviors but provide minimal evidence for the value of including interactivity. © 2016 American Academy of Pain Medicine.

To determine the time to immediate and sustained clinical improvement in pain and sleep quality with pregabalin in patients with fibromyalgia. A post hoc analysis of four 8- to 14-week phase 2-3, placebo-controlled trials of fixed-dose pregabalin (150-600 mg/day) for fibromyalgia, comprising 12 pregabalin and four placebo treatment arms. A total of 2,747 patients with fibromyalgia, aged 18-82 years. Pain and sleep quality scores, recorded daily on 11-point numeric rating scales (NRSs), were analyzed to determine time to immediate improvement with pregabalin, defined as the first of ≥2 consecutive days when the mean NRS score was significantly lower for pregabalin vs placebo in those treatment arms with a significant improvement at endpoint, and time to sustained clinical improvement with pregabalin, defined as a ≥1-point reduction of the baseline NRS score of patient responders who had a ≥30% improvement on the pain NRS, sleep NRS, or Fibromyalgia Impact Questionnaire (FIQ) from baseline to endpoint, or who reported "much improved" or "very much improved" on the Patient Global Impression of Change (PGIC) at endpoint. Significant improvements in pain and sleep quality scores at endpoint vs placebo were seen in 8/12 and 11/12 pregabalin treatment arms, respectively (P < 0.05). In these arms, time to immediate improvements in pain or sleep occurred by day 1 or 2. Time to sustained clinical improvement occurred significantly earlier in pain, sleep, PGIC, and FIQ responders (P < 0.02) with pregabalin vs placebo. Both immediate and sustained clinical improvements in pain and sleep quality occurred faster with pregabalin vs placebo. Wiley Periodicals, Inc.

[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.

Many individuals suffer from various kinds of chronic pain. Some controlled studies on distant healing for chronic pain exist, but no definitive conclusion has been established. To study the effects of distant healing performed by a professional Japanese healer on chronic pain. A double-blind randomized controlled study. Holos University, Fair Grove, Missouri. People suffering from chronic pain (not caused by clear organic diseases or that persists long after a reasonable period of healing following injuries or surgery) were recruited through local radio and newspaper advertising. Subjects were randomly assigned to a treatment group or control group using a double-blind procedure. All subjects met the healer at the initial session at Holos University. At the session, a 20-minute group meditation was performed. The healer went back to Japan after the session and started distant healing only to the treatment group for a 2-month period. All participants were asked to meditate for 20 minutes every day during this 2-month period. The visual analog scale and McGill Pain Questionnaire. A total of 17 subjects were recruited, and 16 subjects completed the study. Comparison of pretreatment and posttreatment visual analog scale indicated a slightly significant effect of distant healing (P=.056). The Present Pain Intensity Scale showed significant improvement in the treatment group compared to the control group (P=.0016). The Pain Rating Index showed improvement in the treatment group, but the difference between both groups was not statistically significant (P=.12).

To investigate the associations between subjective well-being and pain intensity, pain interference, and depression in individuals with physical disabilities. We hypothesized that (1) pain control and (2) pain catastrophizing mediate the effects of subjective well-being on pain intensity, pain interference, and depression. Analyses of cross-sectional data from 96 individuals diagnosed with spinal cord injury, multiple sclerosis, neuromuscular disease, or post-polio syndrome, with average pain intensity of ≥4 (0-10) on at least half the days in the past month. Two models tested study hypotheses using structural equation. Both models showed acceptable model fit. Pain catastrophizing significantly mediated the effect of subjective well-being on pain intensity and pain interference, but not on depression. Pain control did not significantly mediate the effect of subjective well-being on pain intensity, pain interference, or depression. Path coefficients showed significant direct effects of subjective well-being on pain control (β = 0.39), pain catastrophizing (β = -0.61), pain interference (β = -0.48; -0.42), and depression (β = -0.75; -0.78). This study supports the potential of enhancing subjective well-being and lowering pain catastrophizing for reducing pain intensity, pain interference, and depressive symptoms in individuals with chronic pain and a physical disability. The findings indicate that true experiments to test for causal associations are warranted. Implications for rehabilitation The majority of individuals with physical disabilities report having persistent moderate-to-severe pain that may negatively limit daily activities and quality of life. The present cross-sectional study indicates that individuals who reported greater subjective well-being showed significantly lower pain intensity via the mediating effect of lower pain catastrophizing. Since sample size and respective power are low, these findings should be taken as first

Given the public health crisis of opioid overprescribing for pain, there is a need for evidence-based non pharmacological treatment options that effectively reduce pain and depression. We aim to examine the effectiveness of the Integrative Medical Group Visits (IMGV) model in reducing chronic pain and depressive symptoms, as well as increasing pain self-management. This paper details the study design and implementation of an ongoing randomized controlled trial of the IMGV model as compared to primary care visits. The research aims to determine if the IMGV model is effective in achieving: a) a reduction in self-reported pain and depressive symptoms and 2) an improvement in the self-management of pain, through increasing pain self-efficacy and reducing use of self-reported pain medication. We intend to recruit 154 participants to be randomized in our intervention, the IMGV model (n=77) and to usual care (n=77). Usual care of chronic pain through pharmacological treatment has mixed evidence of efficacy and may not improve quality of life or functional status. We aim to conduct a randomized controlled trial to evaluate the effectiveness of the IMGV model as compared to usual care in reducing self-reported pain and depressive symptoms as well as increasing pain management skills.

Infrared (IR)-A irradiation can be useful in back and musculoskeletal pain therapy. In this study joint and vertebral column pain and mobility were measured during two weeks of IR-A irradiation treatment of patients suffering from degenerative osteoarthritis of hip and knee, low back pain, or rheumatoid arthritis. Additionally, before and after IR-A treatment MDA serum levels were measured to check if MDA variations accompany changes in pain intensity and mobility. Two-hundred and seven patients were divided into verum groups getting IR-irradiation, placebo groups getting visible, but not IR irradiation, and groups getting no irradiation. In osteoarthritis significant pain reduction according to Visual Analogue Scale and mobility improvements occurred in the verum group. Even though beneficial mean value changes occurred in the placebo group, the improvements in the placebo and No Irradiation groups were without statistical significance. In low back pain, pain and mobility improvements (by 35-40%) in the verum group were found, too. A delayed (2nd week) mobility improvement in rheumatoid arthritis was seen. However, pain relief was seen immediately. In patients suffering from low back pain or rheumatoid arthritis, the pain and mobility improvements were accompanied by significant changes of MDA serum levels. However, MDA appears not a sensitive biofactor for changes of the pain intensity in degenerative osteoarthritis. Nevertheless, unaffected or lowered MDA levels during intensive IR-A therapy argue against previous reports on free radical formation upon infrared. In conclusion, rapid beneficial effects of IR-A towards musculoskeletal pain and joint mobility loss were demonstrated.

A growing number of women are seeking alternatives to traditional pharmacologic pain management during birth. While there has been an extensive array of nonpharmacologic options developed for labor, there are limited offerings in the postpartum period. The purpose of this quality improvement project was to implement a hydrotherapy protocol in the early postpartum period to improve pain management for women choosing a nonmedicated birth. The postpartum hydrotherapy protocol was initiated in a certified nurse-midwife (CNM) practice in an urban academic medical center. All women who met criteria were offered a 30-minute warm water immersion bath at one hour postpartum. Pain scores were assessed prior to the bath, at 15 minutes after onset, and again at the conclusion (30 minutes). Women who completed the bath were also asked to complete a brief survey on their experience with postpartum hydrotherapy. In women who used the bath (N = 45), there was a significant reduction in pain scores (P < .001) between the onset of the bath and scores at both 15 minutes and 30 minutes. There was no significant difference between pain scores at 15 minutes and 30 minutes (P = .97). Of those women who completed a survey (n = 43), 97.7% reported both that the bath reduced their pain and improved their birth experience. One hundred percent reported they would use it again in another birth. This project demonstrated successful implementation of a hydrotherapy protocol as an alternative or adjunct to medication for early postpartum pain management that significantly reduced pain and improved the birth experience for those who used it. It offers a nonpharmacologic alternative where there have traditionally been limited options. © 2017 by the American College of Nurse-Midwives.

Tramadol was found to be more effective than dexamethasone in post-operative pain control, with long-lasting relief of pain. This study aimed to compare the effects of pre-operative local injections of tramadol and dexamethasone on post-operative pain, nausea and vomiting in patients who underwent tonsillectomy. Sixty patients between 3-13 years of age who were planned for tonsillectomy were included in the study. Patients were divided into three groups. Group 1 was the control group. Patients in Group 2 received 0.3 mg/kg Dexamethasone and Group 3 received 0.1 mg/kg Tramadol injection to the peritonsillary space just before the operation. Patients were evaluated for nausea, vomiting, and pain. When the control and the dexamethasone groups were compared; there were statistically significant differences in pain scores at post-operative 15 and 30 min, whereas there was no statistically significant difference in pain scores at other hours. When the control and tramadol groups were compared, there was a statistically significant difference in pain scores at all intervals. When tramadol and dexamethasone groups were compared, there was no statistically significant difference in pain scores at post-operative 15 and 30 min, 1 and 2 h, whereas there was a statistically significant difference in pain scores at post-operative 6 and 24 h.

There are disparities in the level of symptom severity as perceived by patients and health professionals. There is limited information about patients' and clinicians' global assessment of breakthrough pain control, the need to change analgesics, and change in breakthrough pain over time. To establish whether patients and clinicians independently agree on adequacy of breakthrough pain control, management strategy, and impression of change over time. One hundred patients with breakthrough cancer pain were assessed and followed up one week later by a palliative medicine specialist. The patient and clinician independently answered the same questions about the adequacy of the patient's breakthrough pain control and breakthrough pain management. The results were compared with items on the Breakthrough Pain Assessment Tool (BAT). At initial consultation, 35% of patients rated their breakthrough cancer pain as inadequately controlled compared with 72% of clinicians. Breakthrough pain analgesics were changed in 68% of cases. At one-week follow-up consultation, 62% of patients considered their breakthrough cancer pain to be better, and in 57% of cases, the clinicians also categorized the pain this way. There are significant differences in global impressions of breakthrough pain between patients and pain clinicians that become less disparate as a therapeutic relationship evolves. Therapeutic decisions were based on clinical rather than patient perceptions. Copyright © 2016 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc. All rights reserved.

Pilates method has been recommended for patients with chronic low back pain (CLBP) and the activation of transversus abdominis has been deemed to play an important role in the improvement of these patients. Nevertheless, the evidence of the activation of TrA in Pilates practitioners remains unclear. To assess the effectiveness of 12 weeks of Pilates practice in disability, pain, kinesiophobia and transversus abdominis activation in patients with chronic nonspecific Low Back Pain. A randomized controlled trial was carried out. A single-blind randomized controlled trial with repeated measures at 6 and 12 weeks was carried out. A total of ninety eight patients with low back pain were included and randomly allocated to a Pilates Mat group (PMG) equipment based with apparatus Pilates (PAG) or control group (CG). Roland Morris Disability Questionnaire (RMDQ), visual analog scale (VAS) Tampa Scale of Kinesiophobia (TSK), and transversus abdominis (TrA) activation assessed by real time ultrasound measurement (US) were assessed as outcome measures. Improvement were observed in both intervention groups in all the included variables at 6 and 12 weeks (p<0.001). Faster enhancement was observed in the equipment based Pilates group (p=0.007). Equipment based and mat Pilates modalities are both effective in the improvement of TaA activation in patients with CLBP with associate improvement on pain, function and kinesiophobia. Significant differences were observed after 12 weeks of intervention in PMG and PAG with faster improvement in PAG suggesting that, feedback provided by equipment could help in the interiorization of Pilates principles.

Pain is one of the most common side effects of transcatheter arterial chemoembolization (TACE) treatment. This study aimed to assess the analgesic effect of parecoxib sodium for postoperative pain control in patients with inoperable hepatocellular carcinoma (HCC) undergoing TACE. This randomized placebo-controlled prospective clinical study was conducted at a single cancer centre. Patients were randomly assigned to receive parecoxib sodium (experimental group; n = 60) or 0.9 % sodium chloride (control group; n = 60) 1 h before TACE and once every 12 h for 2 days after TACE. Pain level, morphine consumption, adverse events, and quality of life were evaluated and compared between the two groups. Pain scores, percentage distribution of pain categories, and morphine consumption were significantly lower in the experimental group than in the control group (P < 0.05). Fever score comparisons revealed significantly better body temperature balance in the experimental group than in the control group (P = 0.024). Quality-of-life scores in the experimental group were significantly better than those in the control group (P < 0.05). Our results demonstrate that the perioperative administration of parecoxib significantly improved its effectiveness in the control of postoperative pain after TACE. • Perioperative administration of parecoxib is effective for control of pain after TACE. • COX-2 inhibitors provide effective and safe pain control. • Parecoxib helps improve quality-of-life after TACE for patients with inoperable hepatocellular carcinoma.

OBJECTIVE To assess the efficacy of Sativex, a cannabis-based medicinal extract, as adjuvant treatment in painful diabetic peripheral neuropathy (DPN). RESEARCH DESIGN AND METHODS In this randomized controlled trial, 30 subjects with painful DPN received daily Sativex or placebo. The primary outcome measure was change in mean daily pain scores, and secondary outcome measures included quality-of-life assessments. RESULTS There was significant improvement in pain scores in both groups, but mean change between groups was not significant. There were no significant differences in secondary outcome measures. Patients with depression had significantly greater baseline pain scores that improved regardless of intervention. CONCLUSIONS This first-ever trial assessing the efficacy of cannabis has shown it to be no more efficacious than placebo in painful DPN. Depression was a major confounder and may have important implications for future trials on painful DPN. PMID:19808912

A Randomized, Double-Blind, Placebo-Controlled Trial of Eszopiclone for the Treatment of Insomnia in Patients with Chronic Low Back Pain

2014-01-01

Study Objectives: Insomnia, which is very common in patients with chronic low back pain (LBP), has long been viewed as a pain symptom that did not merit specific treatment. Recent data suggest that adding insomnia therapy to pain-targeted treatment should improve outcome; however, this has not been empirically tested in LBP or in any pain condition treated with a standardized pain medication regimen. We sought to test the hypothesis that adding insomnia therapy to pain-targeted treatment might improve sleep and pain in LBP. Design: Double-blind, placebo-controlled, parallel-group, 1-mo trial. Setting: Duke University Medical Center Outpatient Sleep Clinic. Patients: Fifty-two adult volunteers with LBP of at least 3 mo duration who met diagnostic criteria for insomnia (mean age: 42.5 y; 63% females). Interventions: Subjects were randomized to eszopiclone (ESZ) 3 mg plus naproxen 500 mg BID or matching placebo plus naproxen 500 mg twice a day. Measurements and Results: ESZ significantly improved total sleep time (mean increase: ESZ, 95 min; placebo, 9 min) (primary outcome) and nearly all sleep measures as well as visual analog scale pain (mean decrease: ESZ, 17 mm; placebo, 2 mm) (primary pain outcome), and depression (mean Hamilton Depression Rating Scale improvement ESZ, 3.8; placebo, 0.4) compared with placebo. Changes in pain ratings were significantly correlated with changes in sleep. Conclusions: The addition of insomnia-specific therapy to a standardized naproxen pain regimen significantly improves sleep, pain, and depression in patients with chronic low back pain (LBP). The findings indicate the importance of administering both sleep and pain-directed therapies to patients with LBP in clinical practice and provide strong evidence that improving sleep disturbance may improve pain.

Participants’ self-reported likelihood (from 0% to 100%) of having surgery also reduced more strongly in the digital care program group compared to the control group over the next 1 year (–9.4 percentage points, pp, 95% CI –16.6 to –2.2, P=.01), 2 years (–11.3 pp, 95% CI –20.1 to –2.5, P=.01), and 5 years (–14.6 pp, 95% CI –23.6 to –5.5, P=.002). Interest in surgery (from 0 to 10) also reduced more so in the digital care program compared to control group (–1.0, 95% CI –1.7 to –0.2, P=.01). Participants’ understanding of the condition and treatment options (on a scale from 0 to 4) increased more substantially for participants in the digital care program than those in the control group (0.9, 95% CI 0.6 to 1.3, P<.001). In an analysis on participants that completed the intervention (per protocol analysis) all primary and secondary outcomes remained significant at greater effect magnitudes compared to intention to treat, with those completing the program showing a 61% (95% CI 48 to 74) reduction in VAS pain compared to 21% (95% CI 5 to 38) in the control group (P<.001). Accounting for the cost of administering the program, we estimate net cost savings on surgery alone of US $4340 over 1 year and $7900 over 5 years for those participants completing the digital care program compared to those in the control group receiving treatment-as-usual. In an exploratory subgroup analysis including only participants exhibiting clinical symptoms of osteoarthritis the program proved equally effective.

To compare the effectiveness of proprioceptive neuromuscular facilitation combined with exercise, classic stretching physiotherapy intervention, and educational intervention at improving patient function and pain in patients with patellofemoral pain syndrome. Randomized, controlled, blind trial over four months. Urban population, Spain. Patients undergoing primary care for retropatellar pain. Subjects were allocated on three different treatment options: a proprioceptive neuromuscular facilitation and aerobic exercise group, a classic stretching group, and a control treatment were applied over four months under the supervision of a physiotherapist. Knee Society Score, pain reported (Visual analogue scale) and knee range of motion. Assessments were completed at baseline and after four months. 74 patients were enrolled in the study and distributed between groups. Both the proprioceptive neuromuscular facilitation and classic stretching group showed significant changes in all variables after four months intervention (p < 0.001). The difference in mean Kujala knee score changes between groups (classic stretching group vs. proprioceptive neuromuscular facilitation group vs. control group) at four months was -24.05 (95% confidence interval (CI) -30.19, -17.90), p ≤ 0.001; vs. -39.03 (95% confidence interval (CI) -42.5, -35.5), p ≤ 0.001; vs. -0.238 (95% confidence interval (CI) -1.2, 0.726), p = 0.621, respectively. A proprioceptive neuromuscular facilitation intervention protocol combined with aerobic exercise showed a better outcome than a classic stretching protocol after four months.

A prospective randomized controlled study of VAX-D and TENS for the treatment of chronic low back pain.

Low back pain is one of the most significant medical and socioeconomic problems in modern society. International guidelines call for evidence-based management for the pain and disability associated with musculoskeletal disorders. The purpose of this randomized controlled trial is to address the question of efficacy and appropriateness of vertebral axial decompression (VAX-D) therapy, a new technology that has been shown in clinical research to create negative intradiscal pressures, and has been shown to be effective in treating patients presenting with chronic low back pain (> 3 months duration) with associated leg pain. Successful outcome was defined as a 50% reduction in pain utilizing a 10 cm Visual Analog Pain Scale and an improvement in the level of functioning as measured by patient-nominated disability ratings. Patients were randomly assigned to VAX-D or to TENS which was used as a control treatment or placebo. The TENS treatment demonstrated a success rate of 0%, while VAX-D demonstrated a success rate of 68.4% (p < 0.001). A statistically significant reduction in pain and improvement in functional outcome was obtained in patients with chronic low back pain treated with VAX-D.

We sought to compare recovery of activity and pain control after robotic (ROB) vs abdominal (ABD) sacral colpopexy. Women undergoing ROB and ABD sacral colpopexy wore accelerometers for 7 days preoperatively and the first 10 days postoperatively. They completed postoperative pain diaries and Short Form-36 questionnaires before and after surgery. At 5 days postoperatively, none of the 14 subjects in the ABD group and 4 of 28 (14.3%) in the ROB group achieved 50% total baseline activity counts (P = .283). At 10 days, 5 of 14 (35.7%) in the ABD group and 8 of 26 (30.8%) in the ROB group (P = .972) achieved 50%. Postoperative pain was similar in both groups. Short Form-36 vitality scores were lower (P = .017) after surgery in the ABD group, but not in the ROB group. Women undergoing ROB vs ABD sacral colpopexy do not recover physical activity faster, and pain control is not improved. Copyright © 2012 Mosby, Inc. All rights reserved.

Randomized controlled trial. Patients with Patellofemoral pain (PFP) usually present muscular weakness, pain and impaired motor control. Muscle strengthening is an effective treatment strategy for PFP, but the additional benefits of movement control training remain unknown. Therefore, the aim of this study was to compare the effects of movement control training associated with muscle strengthening, with a conventional program of strengthening alone in women with PFP. Thirty-four women were randomly assigned to two groups. The Strengthening group (S group) performed 12 sessions to strengthen the knee and hip muscles. The Movement Control & Strengthening group (MC&S group) performed the same exercises and movement control training of the trunk and lower limbs. Effects of the treatment (i.e., between-group differences) were calculated using linear mixed models. Primary outcomes were function and pain intensity after completion of the treatment protocol. Secondary outcomes were; muscle strength and kinematic outcomes during the step down task after 4 weeks of treatment; and function and pain intensity 3 and 6 months after randomization. The MC&S group did not present significantly better function (MD -2.5 points, 95% CI;-10.7-5.5) or pain (MD -0.3 points, 95% CI;-1.7-1.0) at 4 weeks. There was a small difference in favour of the MC&S group for AKPS scores at 3 months (MD -8.5 points; 95% CI;-16.8 to -0.3). No significant between-group differences were observed for the other outcomes. Movement control training was no more effective than the isolated strengthening protocol, in terms of pain, function, muscle strength, or kinematics. Copyright © 2017 Elsevier B.V.

Effective pain management after anterior cruciate ligament (ACL) reconstruction improves patient satisfaction and function. To collect and evaluate the available evidence from randomized controlled trials (RCTs) on pain control after ACL reconstruction. Systematic review. A systematic literature review was performed using PubMed, Medline, Google Scholar, UpToDate, Cochrane Reviews, CINAHL, and Scopus following PRISMA guidelines (July 2014). Only RCTs comparing a method of postoperative pain control to another method or placebo were included. A total of 77 RCTs met inclusion criteria: 14 on regional nerve blocks, 21 on intra-articular injections, 4 on intramuscular/intravenous injections, 12 on multimodal regimens, 6 on oral medications, 10 on cryotherapy/compression, 6 on mobilization, and 5 on intraoperative techniques. Single-injection femoral nerve blocks provided superior analgesia to placebo for up to 24 hours postoperatively; however, this also resulted in a quadriceps motor deficit. Indwelling femoral catheters utilized for 2 days postoperatively provided superior analgesia to a single-injection femoral nerve block. Local anesthetic injections at the surgical wound site or intra-articularly provided equivalent analgesia to regional nerve blocks. Continuous-infusion catheters of a local anesthetic provided adequate pain relief but have been shown to cause chondrolysis. Cryotherapy improved analgesia compared to no cryotherapy in 4 trials, while in 4 trials, ice water and water at room temperature provided equivalent analgesic effects. Early weightbearing decreased pain compared to delayed weightbearing. Oral gabapentin given preoperatively and oral zolpidem given for the first week postoperatively each decreased opioid consumption as compared to placebo. Ibuprofen reduced pain compared to acetaminophen. Oral ketorolac reduced pain compared to hydrocodone-acetaminophen. Regional nerve blocks and intra-articular injections are both effective forms of analgesia

Ambulatory surgery is on the rise, with an unmet need for optimum pain control in ambulatory surgery centers worldwide. It is important that there is a proportionate increase in the availability of acute pain-management services to match the rapid rise of clinical patient load with pain issues in the ambulatory surgery setting. Focus on ambulatory pain control with its special challenges is vital to achieve optimum pain control and prevent morbidity and mortality. Management of perioperative pain in the ambulatory surgery setting is becoming increasingly complex, and requires the employment of a multimodal approach and interventions facilitated by ambulatory surgery pain specialists, which is a new concept. A focused ambulatory pain specialist on site at each ambulatory surgery center, in addition to providing safe anesthesia, could intervene early once problematic pain issues are recognized, thus preventing emergency room visits, as well as readmissions for uncontrolled pain. This paper reviews methods of acute-pain management in the ambulatory setting with risk stratification, the utilization of multimodal interventions, including pharmacological and nonpharmacological options, opioids, nonopioids, and various routes with the goal of preventing delayed discharge and unexpected hospital admissions after ambulatory surgery. Continued research and investigation in the area of pain management with outcome studies in acute surgically inflicted pain in patients with underlying chronic pain treated with opioids and the pattern and predictive factors for pain in the ambulatory surgical setting is needed.

Background Trigger points have been shown to be active in many myofascial pain syndromes. Treatment of trigger point pain and dysfunction may be explained through the mechanisms of central and peripheral paradigms. This study aimed to investigate whether the mind/body treatment of Neuro Emotional Technique (NET) could significantly relieve pain sensitivity of trigger points presenting in a cohort of chronic neck pain sufferers. Methods Sixty participants presenting to a private chiropractic clinic with chronic cervical pain as their primary complaint were sequentially allocated into treatment and control groups. Participants in the treatment group received a short course of Neuro Emotional Technique that consists of muscle testing, general semantics and Traditional Chinese Medicine. The control group received a sham NET protocol. Outcome measurements included pain assessment utilizing a visual analog scale and a pressure gauge algometer. Pain sensitivity was measured at four trigger point locations: suboccipital region (S); levator scapulae region (LS); sternocleidomastoid region (SCM) and temporomandibular region (TMJ). For each outcome measurement and each trigger point, we calculated the change in measurement between pre- and post- treatment. We then examined the relationships between these measurement changes and six independent variables (i.e. treatment group and the above five additional participant variables) using forward stepwise General Linear Model. Results The visual analog scale (0 to 10) had an improvement of 7.6 at S, 7.2 at LS, 7.5 at SCM and 7.1 at the TMJ in the treatment group compared with no improvement of at S, and an improvement of 0.04 at LS, 0.1 at SCM and 0.1 at the TMJ point in the control group, (P < 0.001). Conclusion After a short course of NET treatment, measurements of visual analog scale and pressure algometer recordings of four trigger point locations in a cohort of chronic neck pain sufferers were significantly improved when

The study had two aims--to determine the efficacy of a family-based cognitive-behavioral pain management intervention for adolescents with sickle cell disease (SCD) in (1) reducing pain and improving health-related variables and (2) improving psychosocial outcomes. Each adolescent and a family support person were randomly assigned to receive a brief pain intervention (PAIN) (n = 27) or a disease education attention control intervention (DISEASE ED) (n = 26) delivered at home. Assessment of primary pain and health-related variables (health service use, pain coping, pain-related hindrance of goals) and secondary psychosocial outcomes (disease knowledge, disease self-efficacy, and family communication) occurred at baseline (prior to randomization), post-intervention, and one-year follow-up. Change on outcomes did not differ significantly by group at either time point. When groups were combined in exploratory analyses, there was evidence of small to medium effects of intervention on health-related and psychosocial variables. Efforts to address barriers to participation and improve feasibility of psychosocial interventions for pediatric SCD are critical to advancing development of effective treatments for pain. Sample size was insufficient to adequately test efficacy, and analyses did not support this focused cognitive-behavioral pain management intervention in this sample of adolescents with SCD. Exploratory analyses suggest that comprehensive interventions, that address a broad range of skills related to disease management and adolescent health concerns, may be more effective in supporting teens during healthcare transition.

Treatment options in painful diabetic neuropathy.

PubMed

Nash, T P

1999-01-01

Diabetic neuropathy is common in patients with diabetes mellitus, and 7.5% of diabetics experience pain from diabetic neuropathy. Complications of diabetes mellitus are more common where control of the disease is not optimal. By improving the control of the disease, both the neuropathy and the pain it can produce may be improved. The pain of diabetic neuropathy can frequently be controlled using analgesics, antidepressants, anticonvulsants, topical capsaicin, and neuromodulation, either alone or in any combination.

Non-specific back pain in children and adolescents has a high prevalence. The aim of this study is to show a Juvenile Back School (JBS) programme and its results in our hospital. A total of 139 patients referred to a Juvenile Back School for advice due to of pain, deformity or back asymmetry were included in a prospective observational study. age, gender, pain, correct postures, sports activities, adherence to JBS and appreciation of these parameters by their parents. VARIABLES were measured with a numerical pain scale and with a survey completed in the first session and 3 months after finishing the JBS. A total of 119 patients finished the study (78 female and 41 male).The average was 13.97±2.29 years (9-20). Three months after JBS, the median pain intensity was reduced from 3 to 0 (P<.0001). There was an improvement in patient postures from 21% to 83% (P<.0001). Patients did not increase their sport activity after the JBS, although its regular practice was linked with pain improvement after JBS (P<.02).Performing exercises did not lead to a decrease in pain. There was a poor correlation between parents and children in the evaluation of post-JBS pain. A back school programme could probably contribute to reduce non-specific back pain and improve postural behaviour in young people. Copyright © 2012 Asociación Española de Pediatría.

Opioid analgesics are simultaneously indispensable medicines for the treatment of moderate to severe pain and are harmful when abused. The challenge for governments is to balance the obligation to prevent diversion, trafficking, and abuse of opioids with the equally important obligation to ensure their availability and accessibility for the relief of pain and suffering. Over the last 30 years, significant progress has been made toward improving access to opioids as measured by increasing global medical opioid consumption. However, this progress is marked by ongoing large disparities among countries, with most increases in medical opioid consumption attributed to high-income countries, not low- and middle-income countries (LMICs). The International Pain Policy Fellowship (IPPF) was developed by the Pain & Policy Studies Group, with the central goal of developing national leaders from LMICs and empowering them to improve availability and accessibility of opioids for the treatment of pain. To date, two classes of fellows have been selected, representing 17 fellows from 15 countries. Progress achieved by the leadership of three fellows from Sierra Leone, Colombia, and Serbia is highlighted in this paper. The fellows from each country were successful at initiating collaboration with relevant governmental bodies, national authorities, and professional societies, which resulted in a new supply of oral opioids in Sierra Leone and Serbia, and improvements in the distribution of already available opioids in Colombia. All fellows were instrumental in facilitating evaluation of national policy. The IPPF program empowers fellows with the necessary knowledge, skills, and guidance to improve the availability and accessibility of opioids for the treatment of pain.

Depression and pain may sometimes be related conditions. Occasionally, depression may be associated with physical symptoms, such as back pain and headache. Moreover, depression may impair the subjective response to pain and is likely to influence the pain feeling. Conversely, chronic pain may represent an emotional condition as well as physical sensation, and can influence both the mood and behaviour. To better understand the relationship between pain and depression, we therefore assessed the pain threshold and the tolerance pain threshold in patients with depressive disorders. We conducted a case-control study and selected patients who had recently received a diagnosis of major depression (DSM-IV), before treatment, and without any significant pain complaints. Age- and sex-matched healthy controls were also included. Tactile and pain thresholds were assessed in all subjects through an electrical stimulation test. All results were compared between the groups. 27 patients and 27 age-matched healthy controls were included in the study. Tactile, pain and tolerance thresholds were evaluated in all subjects. The pain threshold and pain tolerance were lower in patients with major depression than controls. All differences were statistically significant (p<0.05). These results suggest the abnormal processing of pain stimuli in depressive disorders. Copyright © 2015 Elsevier B.V. All rights reserved.

Determine whether an adjustable chair with a curved or a flat seat pan improved monthly back and hip pain scores in sewing machine operators. This 4-month intervention study randomized 293 sewing machine operators with back and hip pain. The participants in the control group received a placebo intervention, and participants in the intervention groups received the placebo intervention and one of the two intervention chairs. Compared with the control group, mean pain improvement for the flat chair intervention was 0.43 points (95% CI = 0.34, 0.51) per month, and mean pain improvement for the curved chair intervention was 0.25 points (95% CI = 0.16, 0.34) per month. A height-adjustable task chair with a swivel function can reduce back and hip pain in sewing machine operators. The findings may be relevant to workers who perform visual- and hand-intensive manufacturing jobs.

Brief submaximal isometric exercise improves cold pressor pain tolerance.

Exercise-induced hypoalgesia (EIH), or the inhibition of pain following physical exercise, has been demonstrated in adults, but its mechanisms have remained unclear due to variations in methodology. This study aimed to address methodological imitations of past studies and contribute to the literature demonstrating the generalizability of EIH to brief submaximal isometric exercise and cold pressor pain. Young adults (n = 134) completed a baseline cold pressor trial, maximal voluntary contraction (hand grip strength) assessment, 10-min rest, and either a 2-min submaximal isometric handgrip exercise or a sham exercise in which no force was exerted, followed by a cold pressor posttest. Results indicated that cold pressor pain tolerance significantly increased during the exercise condition, but not during the sham exercise condition. Exercise did not affect pain intensity and marginally affected pain unpleasantness ratings. These findings suggest that submaximal isometric exercise can improve cold pressor pain tolerance but may have an inconsistent analgesic effect on ratings of cold pressor pain.

This study protocol will evaluate the effectiveness and safety during labor and delivery of the Kinesio Taping bandage for pain sensation, satisfaction of patients, and obstetric and neonatal outcomes. A randomized controlled trial with 60 participants divided into two groups will be conducted. The intervention group will receive bandage application on the vertebral regions corresponding to uterine dermatomes - from T10 to L1 and from S2 to S4. The control group will receive bandage application away from uterine dermatomes, from T1 to T4. The primary endpoint is pain during labor. Secondary endpoints are perinatal outcomes and patient satisfaction with the bandage and with her labor. Pain levels will be evaluated on an hourly basis during labor, and intention-to-treat analysis will be performed. Risk ratios and 95% confidence intervals will be calculated. Findings on effectiveness of pain control with no adverse effects to both the mother and neonate are the first step in evaluating the systematic use of Kinesio Taping during labor. Since self-control may affect birthing experience satisfaction, discovering new alternatives for pain control may allow for a better experience. © 2017 John Wiley & Sons Australia, Ltd.

Poorly controlled postoperative pain: prevalence, consequences, and prevention

Gan, Tong J

2017-01-01

This review provides an overview of the clinical issue of poorly controlled postoperative pain and therapeutic approaches that may help to address this common unresolved health-care challenge. Postoperative pain is not adequately managed in greater than 80% of patients in the US, although rates vary depending on such factors as type of surgery performed, analgesic/anesthetic intervention used, and time elapsed after surgery. Poorly controlled acute postoperative pain is associated with increased morbidity, functional and quality-of-life impairment, delayed recovery time, prolonged duration of opioid use, and higher health-care costs. In addition, the presence and intensity of acute pain during or after surgery is predictive of the development of chronic pain. More effective analgesic/anesthetic measures in the perioperative period are needed to prevent the progression to persistent pain. Although clinical findings are inconsistent, some studies of local anesthetics and nonopioid analgesics have suggested potential benefits as preventive interventions. Conventional opioids remain the standard of care for the management of acute postoperative pain; however, the risk of opioid-related adverse events can limit optimal dosing for analgesia, leading to poorly controlled acute postoperative pain. Several new opioids have been developed that modulate μ-receptor activity by selectively engaging intracellular pathways associated with analgesia and not those associated with adverse events, creating a wider therapeutic window than unselective conventional opioids. In clinical studies, oliceridine (TRV130), a novel μ-receptor G-protein pathway-selective modulator, produced rapid postoperative analgesia with reduced prevalence of adverse events versus morphine.

Introduction Low back pain (LBP) is the leading cause of disability worldwide. Of those patients who present to primary care with acute LBP, 40% continue to report symptoms 3 months later and develop chronic LBP. Although it is possible to identify these patients early, effective interventions to improve their outcomes are not available. This double-blind (participant/outcome assessor) randomised controlled trial will investigate the efficacy of a brief educational approach to prevent chronic LBP in ‘at-risk’ individuals. Methods/analysis Participants will be recruited from primary care practices in the Sydney metropolitan area. To be eligible for inclusion participants will be aged 18–75 years, with acute LBP (<4 weeks’ duration) preceded by at least a 1 month pain-free period and at-risk of developing chronic LBP. Potential participants with chronic spinal pain and those with suspected serious spinal pathology will be excluded. Eligible participants who agree to take part will be randomly allocated to receive 2×1 h sessions of pain biology education or 2×1 h sessions of sham education from a specially trained study physiotherapist. The study requires 101 participants per group to detect a 1-point difference in pain intensity 3 months after pain onset. Secondary outcomes include the incidence of chronic LBP, disability, pain intensity, depression, healthcare utilisation, pain attitudes and beliefs, global recovery and recurrence and are measured at 1 week post-intervention, and at 3, 6 and 12 months post LBP onset. Ethics/dissemination Ethical approval was obtained from the University of New South Wales Human Ethics Committee in June 2013 (ref number HC12664). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conference meetings.

Standard guidelines for cancer pain treatment routinely recommend training patients to reduce barriers to pain relief, use medications appropriately, and communicate their pain-related needs. Methods are needed to reduce professional time required while achieving sustained intervention effectiveness. In a multisite, randomized controlled trial, this study tested a pain training method versus a nutrition control. At six oncology clinics, physicians (N=22) and nurses (N=23) enrolled patients (N=93) who were over 18 years of age, with cancer diagnoses, pain, and a life expectancy of at least 6 months. Pain training and control interventions were matched for materials and method. Patients watched a video followed by about 20 min of manual-standardized training with an oncology nurse focused on reviewing the printed material and adapted to individual concerns of patients. A follow-up phone call after 72 h addressed individualized treatment content and pain communication. Assessments at baseline, one, three, and 6 months included barriers, the Brief Pain Inventory, opioid use, and physician and nurse ratings of their patients' pain. Trained versus control patients reported reduced barriers to pain relief (P<.001), lower usual pain (P=.03), and greater opioid use (P<.001). No pain training patients reported severe pain (>6 on a 0-10 scale) at 1-month outcomes (P=.03). Physician and nurse ratings were closer to patients' ratings of pain for trained versus nutrition groups (P=.04 and <.001, respectively). Training efficacy was not modified by patient characteristics. Using video and print materials, with brief individualized training, effectively improved pain management over time for cancer patients of varying diagnostic and demographic groups.

Appropriate pain management affects outcome after hip fracture surgery. Although multimodal pain management is commonly used for pain control for patients undergoing elective surgery, few studies have evaluated its use in those undergoing hip fracture surgery. This prospective randomized study was designed to determine the clinical value of multimodal pain management with preemptive pain medication and intraoperative periarticular multimodal drug injections in patients undergoing bipolar hip hemiarthroplasty. Of eighty-two cognitively intact elderly patients about to undergo bipolar hemiarthroplasty after a hip fracture, forty-three were randomly assigned to receive preemptive pain medication and intraoperative periarticular injections (Group I) and thirty-nine were assigned to not receive preemptive medication and injections (Group II). These two groups were compared with regard to the pain level on postoperative days one, four, and seven; at discharge; and when they started walking and standing exercises. Total amounts of fentanyl used, the frequency of use of patient-controlled analgesia, patient satisfaction at discharge, and perioperative complications were recorded. Group I had a lower pain level than Group II on postoperative days one and four, but no intergroup difference in pain level was observed on postoperative day seven. The total amount of fentanyl used and the frequency of use of patient-controlled analgesia were also lower in Group I. Patient satisfaction at discharge was higher in Group I. No significant intergroup differences were found in the times until the patients walked or performed standing exercises or in the complications. Multimodal pain management provides additional pain relief until the fourth postoperative day, improves patient satisfaction at discharge, and reduces total narcotic consumption for postoperative pain management after hip hemiarthroplasty for hip fractures.

The role of exercise therapy in improving pain-related clinical outcomes and trunk muscle activity in patients with chronic low back pain (CLBP) has been widely reported. There is little information on the effect of proprioceptive neuromuscular facilitation (PNF) training in patients with CLBP. The purpose of the present study was therefore to investigate the persistence of the effects of PNF training on pain intensity, functional disability, patient satisfaction, health-related quality of life (HRQOL) and lower back muscle activity in patients with CLBP. Forty-two participants with CLBP were randomly assigned either to 4-week PNF training or to a control group receiving a Low back pain educational booklet. Pain-related outcomes, including pain intensity, functional disability, patient satisfaction, HRQOL and lumbar erector spinae (LES) muscle activity, were measured before and after the intervention, and at a follow-up session 12 weeks after the last intervention session. Compared with the control group, after undergoing a 4-week PNF training intervention, participants showed a significant reduction in pain intensity and functional disability, and improved patient satisfaction and HRQOL (p < 0.01). These effects were still significant at the 12-week follow-up assessment (p < 0.01). LES muscle activity in the PNF training group was significantly increased throughout the measurement periods compared with controls (p < 0.01). The study found that 4-week PNF training has positive long-term effects on pain-related outcomes, and increases lower back muscle activity in patients with CLBP.

Neurorehabilitation interventions to improve lower limb function and neuropathic pain have had limited success in people with chronic, incomplete spinal cord injury (iSCI). We hypothesized that intense virtual reality (VR)-augmented training of observed and executed leg movements would improve limb function and neuropathic pain. Patients used a VR system with a first-person view of virtual lower limbs, controlled via movement sensors fitted to the patient's own shoes. Four tasks were used to deliver intensive training of individual muscles (tibialis anterior, quadriceps, leg ad-/abductors). The tasks engaged motivation through feedback of task success. Fourteen chronic iSCI patients were treated over 4 weeks in 16 to 20 sessions of 45 minutes. Outcome measures were 10 Meter Walking Test, Berg Balance Scale, Lower Extremity Motor Score, Spinal Cord Independence Measure, Locomotion and Neuropathic Pain Scale (NPS), obtained at the start and at 4 to 6 weeks before intervention. In addition to positive changes reported by the patients (Patients' Global Impression of Change), measures of walking capacity, balance, and strength revealed improvements in lower limb function. Intensity and unpleasantness of neuropathic pain in half of the affected participants were reduced on the NPS test. Overall findings remained stable 12 to 16 weeks after termination of the training. In a pretest/posttest, uncontrolled design, VR-augmented training was associated with improvements in motor function and neuropathic pain in persons with chronic iSCI, several of which reached the level of a minimal clinically important change. A controlled trial is needed to compare this intervention to active training alone or in combination.

To assess if manual therapy (MT) in the treatment of plantar fasciitis (PF) patients improves pain and function more effectively than other interventions. A systematic review of all randomized control trials (RCTs) investigating the effects of MT in the treatment of human patients with PF, plantar fasciosis, and heel pain published in English on PubMed, CINAHL, Cochrane, and Web of Science databases was conducted. Research quality was appraised utilizing the PEDro scale. Cohen's d effect sizes (ES) and associated 95% confidence intervals (CI) were calculated between treatment groups. Seven RCTs were selected that employed MT as a primary independent variable and pain and function as dependent variables. Inclusion of MT in treatment yielded greater improvement in function (6 of 7 studies, CI that did not cross zero in 14 of 25 variables, ES = 0.5-21.5) and algometry (3 of 3 studies, CI that did not cross zero in 9 of 10 variables, ES = 0.7-3.0) from 4 weeks to 6 months when compared to interventions such as stretching, strengthening, or modalities. Though pain improved with the inclusion of MT, ES calculations favored MT in only 2 of 6 studies (3 of 13 variables) and was otherwise equivalent in effectiveness to comparison interventions. MT is clearly associated with improved function and may be associated with pain reduction in PF patients. It is recommended that clinicians consider use of both joint and soft tissue mobilization techniques in conjunction with stretching and strengthening when treating patients with PF.

The study aimed to assess the impact of hydrotherapy on pain, function, and muscle function in older women with knee osteoarthritis. A randomized controlled trial was conducted to evaluate the efficacy of hydrotherapy in women with knee osteoarthritis. Seventy-three women aged 65 and older were randomized to hydrotherapy (n=36) or a control group (n=37). The hydrotherapy group received the intervention program in a heated pool (twice per week for six weeks) and an educational protocol while the control group received an educational protocol only. Primary outcomes (before and post-treatment) were pain intensity (0-100) and function (0-100), assessed with the WOMAC questionnaire. Secondary outcomes (before and post-treatment) were knee extensor and knee flexor muscle performance (strength, power, and endurance), assessed by an isokinetic dynamometer. The magnitude of change between the groups for the outcomes was calculated using linear regression models adjusted by baseline outcome values. The hydrotherapy group had better outcomes for pain (adjusted mean difference=11 points, 95% CI: 3-18) and function (adjusted mean difference=12 points, 95% CI: 5-18). Patients receiving hydrotherapy had better performance for knee flexor and extensor strength, knee flexor power, and knee extensor endurance. Older women with knee osteoarthritis are likely to have benefits from a course of hydrotherapy exercises.

Psychogenic nonepileptic seizures (PNES) can be challenging to diagnose, but certain clinical features can help to distinguish PNES from epileptic seizures. The purpose of this study is to assess chronic pain and prescribed pain medication use in PNES patients. A case-controlled, retrospective analysis was performed examining pain medication use in 85 PNES patients versus an active control group of 85 patients with idiopathic generalized epilepsy (IGE). Chronic pain was more frequent among PNES patients (N=40) than active controls (N=10) (p<0.0001). Reported use of prescription pain medication was higher among PNES patients (N=20) versus active controls (N=6) (p=0.0048). The Positive Predictive Value of prescription pain medications for PNES patients was 76.9%. Opioid use in the PNES population was higher compared with active controls (p=0.0096). When excluding patients with a dual diagnosis of PNES and epilepsy from the latter two analyses and comparing these results to those that included this patient population, no statistically significant difference in results was found. Patients with PNES are more likely than those with IGE to report chronic pain disorders. A history of chronic pain and opioid use among patients with seizures raises the possibility of PNES. Among patients with PNES and chronic pain, a psychogenic etiology for pain and non-opiate pain management strategies should be considered. Copyright © 2012 Elsevier Inc. All rights reserved.

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

Study Design Systematic review with meta-analysis. Background The addition of hip strengthening to knee strengthening for persons with patellofemoral pain has the potential to optimize treatment effects. There is a need to systematically review and pool the current evidence in this area. Objective To examine the efficacy of hip strengthening, associated or not with knee strengthening, to increase strength, reduce pain, and improve activity in individuals with patellofemoral pain. Methods A systematic review of randomized and/or controlled trials was performed. Participants in the reviewed studies were individuals with patellofemoral pain, and the experimental intervention was hip and knee strengthening. Outcome data related to muscle strength, pain, and activity were extracted from the eligible trials and combined in a meta-analysis. Results The review included 14 trials involving 673 participants. Random-effects meta-analyses revealed that hip and knee strengthening decreased pain (mean difference, -3.3; 95% confidence interval [CI]: -5.6, -1.1) and improved activity (standardized mean difference, 1.4; 95% CI: 0.03, 2.8) compared to no training/placebo. In addition, hip and knee strengthening was superior to knee strengthening alone for decreasing pain (mean difference, -1.5; 95% CI: -2.3, -0.8) and improving activity (standardized mean difference, 0.7; 95% CI: 0.2, 1.3). Results were maintained beyond the intervention period. Meta-analyses showed no significant changes in strength for any of the interventions. Conclusion Hip and knee strengthening is effective and superior to knee strengthening alone for decreasing pain and improving activity in persons with patellofemoral pain; however, these outcomes were achieved without a concurrent change in strength.

The present investigation is a preliminary double-blind, controlled placebo, randomized clinical trial with a six month follow-up period. The study aimed to assess the efficacy of type A botulinum toxin (Botox, Allergan, Inc. Irvine, CA) to treat myofascial pain symptoms and to reduce muscle hyperactivity in bruxers. Twenty patients (ten males, ten females; age range 25-45) with a clinical diagnosis of bruxism and myofascial pain of the masticatory muscles were enrolled in a double-blind, controlled placebo, randomized clinical trial, with a treatment group (ten subjects treated with botulinum toxin injections- BTX-A) and a control group (ten subjects treated with saline placebo injections). A number of objective and subjective clinical parameters (pain at rest and during chewing; mastication efficiency; maximum nonassisted and assisted mouth opening, protrusive and laterotrusive movements; functional limitation during usual jaw movements; subjective efficacy of the treatment; tolerance of the treatment) were assessed at baseline time and at one week, one month, and six months follow-up appointments. Descriptive analysis showed that improvements in both objective (range of mandibular movements) and subjective (pain at rest; pain during chewing) clinical outcome variables were higher in the Botox treated group than in the placebo treated subjects. Patients treated with BTX-A had a higher subjective improvement in their perception of treatment efficacy than the placebo subjects. Differences were not significant in some cases due to the small sample size. Results from the present study supported the efficacy of BTX-A to reduce myofascial pain symptoms in bruxers, and provided pilot data which need to be confirmed by further research using larger samples.

Isometric activation (ISOM) of deep multifidi muscles (MF) can influence postural adjustments and primary motor cortex (M1) function in chronic low back pain (CLBP). In order to better understand how ISOM impacts on CLBP condition, the present study contrasted ISOM after-effects on M1 function, MF postural activation and pain with another training, the global activation of paravertebral muscles (GLOB, hip extension). The main objective of this study was to compare the effects of ISOM and GLOB (3-week training each) on MF postural activation and M1 function in a CLBP population. Twenty-four people with CLBP were randomly allocated to ISOM and GLOB groups for a 3-week daily practice. Pre/post-training after-effects were assessed by the onset of superficial MF (MF-S) activation during ballistic limb movements (bilateral shoulder flexion in standing; unilateral hip extension in prine lying), MF-S corticomotor control tested by transcranial magnetic stimulation of M1, and assessment of pain, kinesiophobia and disability by standardized questionnaires. Both ISOM and GLOB improved pain and disability. However, only ISOM influenced M1 function (decreased corticospinal excitability and increased intracortical inhibition), fastened MF-S postural activation and decreased kinesiophobia. Changes of corticospinal excitability and of MF-S postural adjustments suggest that ISOM better influenced brain plasticity. Future studies should further test whether our novel findings relate to an influence of the exercises on the lumbopelvic control of different muscles and on cognitive function. Clinically, individual's evaluation remains warranted before prescribing one or the other of these two conventional exercises for reducing pain. This original study presents how motor control exercises can influence brain plasticity and postural control in chronic low back pain. This knowledge will impact on the decision of clinicians to prescribe specific exercises with a view of improving motor

Background Improvements in software and design and reduction in cost have made virtual reality (VR) a practical tool for immersive, three-dimensional (3D), multisensory experiences that distract patients from painful stimuli. Objective The objective of the study was to measure the impact of a onetime 3D VR intervention versus a two-dimensional (2D) distraction video for pain in hospitalized patients. Methods We conducted a comparative cohort study in a large, urban teaching hospital in medical inpatients with an average pain score of ≥3/10 from any cause. Patients with nausea, vomiting, dementia, motion sickness, stroke, seizure, and epilepsy and those placed in isolation were excluded. Patients in the intervention cohort viewed a 3D VR experience designed to reduce pain using the Samsung Gear Oculus VR headset; control patients viewed a high-definition, 2D nature video on a 14-inch bedside screen. Pre- and postintervention pain scores were recorded. Difference-in-difference scores and the proportion achieving a half standard deviation pain response were compared between groups. Results There were 50 subjects per cohort (N=100). The mean pain reduction in the VR cohort was greater than in controls (−1.3 vs −0.6 points, respectively; P=.008). A total of 35 (65%) patients in the VR cohort achieved a pain response versus 40% of controls (P=.01; number needed to treat=4). No adverse events were reported from VR. Conclusions Use of VR in hospitalized patients significantly reduces pain versus a control distraction condition. These results indicate that VR is an effective and safe adjunctive therapy for pain management in the acute inpatient setting; future randomized trials should confirm benefit with different visualizations and exposure periods.

Cancer pain is complex, and despite the introduction of the WHO cancer pain ladder, few studies have looked at the prevalence of adjuvant medication use in an inpatient palliative medicine unit. In this study, we evaluate the use of adjuvant pain medications in patients admitted to an inpatient palliative care unit and whether their use affects pain scores or opiate dosing. In this retrospective observational study, patients admitted to the inpatient palliative care unit over a 3-month period with a diagnosis of cancer on opioid therapy were selected. Data pertaining to demographics, diagnosis, oral morphine dose equivalent of the opioid at the time of discharge, adjuvant analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and pain scores as reported by nurses and physicians were collected. Seventy-seven patients were eligible over a 3-month period, out of which 65 (84 %) were taking an adjuvant medication. The most commonly prescribed adjuvant was gabapentin (70 %). Fifty-seven percent were taking more than one adjuvant. There were more women in the group receiving adjuvants (57 vs. 17%, p = 0.010). Those without adjuvants compared with those on adjuvants did not have worse pain scores on discharge as reported by physicians (0.8 ± 0.8 vs. 1.0 ± 0.7, p = 0.58) or nurses (2.0 ± 2.7 vs. 2.1 ± 2.6, p = 0.86). There was no difference in morphine equivalent doses of the opioid in both groups (median (min, max); 112 (58, 504) vs. 200 (30, 5,040)) at the time of discharge; 75-80 % of patients had improvement in pain scores as measured by a two-point reduction in numerical rating scale (NRS). This study shows that adjuvant medications are commonly used for treating pain in patients with cancer. More than half of study population were on two adjuvants or an adjuvant plus NSAID along with an opioid. We did not demonstrate any benefit in terms of improved pain scores or opioid doses with adjuvants, but this could reflect confounding variables and physician choice

Patients' self-management skills are affected by their knowledge, activities, and attitudes toward pain management. This trial aimed to test the Self Care Improvement through Oncology Nursing (SCION)-PAIN program, a multimodular structured intervention to reduce patients' barriers to self-management of cancer pain. Two hundred sixty-three patients with diagnosed malignancy, pain>3 days, and average pain > or = 3/10 participated in a cluster-randomized trial on 18 wards in 2 German university hospitals. Patients on the intervention wards received, in addition to standard pain treatment, the SCION-PAIN program consisting of 3 modules: pharmacologic, nonpharmacologic pain management, and discharge management. The intervention was conducted by specially trained cancer nurses and included components of patient education, skills training, and counseling. Starting with admission, patients received booster sessions every third day and one follow-up telephone counseling session within 2 to 3 days after discharge. Patients in the control group received standard care. Primary end point was the group difference in patient-related barriers to self-management of cancer pain (Barriers Questionnaire-BQ II) 7 days after discharge. The SCION-PAIN program resulted in a significant reduction of patient-related barriers to pain management 1 week after discharge from the hospital: mean difference on BQ II was -0.49 points (95% confidence interval -0.87 points to -0.12 points; P=0.02). Furthermore, patients showed improved adherence to pain medication; odds ratio 8.58 (95% confidence interval 1.66-44.40; P=0.02). A post hoc analysis indicated reduced average and worst pain intensity as well as improved quality of life. This trial reveals the positive impact of a nursing intervention to improve patients' self-management of cancer pain. Copyright © 2014 International Association for the Study of Pain.

To evaluate the efficacy of action learning for improving cancer related pain management in the acute healthcare settings. Despite the prevalent use of action learning in private, public, clinical and non-clinical settings, no studies were found in the literature that either examined cancer pain management or used action learning as an approach to improve patient care in acute healthcare settings. An intervention pre - posttest design was adopted using an action learning programme (ALPs) as the intervention. Healthcare professionals' knowledge, attitudes and practice were assessed and evaluated before and after the implementation of the six-month ALPs. A pre and post audit and survey were conducted for data collection. The data were collected from the entire population of 170 healthcare professionals in one healthcare organisation. The management of cancer related pain improved significantly following the intervention. Significant improvement were also seen in healthcare professionals' knowledge, attitudes with improved cancer related pain management as a consequence of this. Despite many organisational challenges to practice development and collaborative working in healthcare settings there is evidence that action learning can achieve positive outcomes for improving CRP and supporting collaborative working. Action learning needs to be considered as a strategy for achieving high quality standards. © 2016 John Wiley & Sons Ltd.

Fatigue is frequently found in chronic pain patients (CPPs) and may be etiologically related to the presence of pain. Fishbain et al. have recently demonstrated that chronic low back pain (LBP) and chronic neck pain patients are more fatigued than controls. The purpose of this study was to determine whether chronic LBP- and chronic neck pain-associated fatigue responded to multidisciplinary multimodal treatment not specifically targeted to the treatment of fatigue. A total of 85 chronic LBP and 33 chronic neck pain patients completed the Multidimensional Fatigue Inventory (MFI), Neuropathic Pain Scale (NPS), and Beck Depression Inventory on admission. In addition, an information tool was completed on each CPP by the senior author. This tool listed demographic information, primary and secondary pain diagnoses, Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) psychiatric diagnoses assigned, pain location, pain precipitating event, type of injury, years in pain, number of surgeries, type of surgery, type of pain pattern, opioids consumed per day in morphine equivalents, worker compensation status, and whether, according to the clinical examination, the CPP had a neuropathic pain component. At completion of the multidisciplinary multimodal treatment, each CPP again completed the MFI. Student's t-test was utilized to test for statistical changes on the MFI five scales from pre- to post-treatment. Pearson and point-biserial correlations were utilized to determine which variables significantly correlated with MFI change scores. Variables found significant at less than or equal to 0.01 were utilized in a stepwise aggression analysis to find variables predictive of change in MFI scores. Multidisciplinary pain facility. Chronic LBP and chronic neck pain patients. Multidisciplinary multimodal treatment significantly improved CPP fatigue as measured by the MFI. The available variables utilized to predict fatigue best explained only a small percentage

The aim of this study was to investigate the effectiveness of a quality improvement activity for pain management in patients with extremity injury in the emergency department (ED). This was a retrospective interventional study. The patient group consisted of those at least 19 years of age who visited the ED and were diagnosed with International Classification of Diseases codes S40-S99 (extremity injuries). The quality improvement activity consisted of three measures: a survey regarding activities, education, and the triage nurse's pain assessment, including change of pain documentation on electronic medical records. The intervention was conducted from January to April in 2014 and outcome was compared between May and August in 2013 and 2014. The primary outcome was the rate of analgesic prescription, and the secondary outcome was the time to analgesic prescription. A total of 1,739 patients were included, and 20.3% of 867 patients in the pre-intervention period, and 28.8% of 872 patients in the post-intervention period received analgesics (P< 0.001). The prescription rate of analgesics for moderate-to-severe injuries was 36.4% in 2013 and 44.5% in 2014 (P=0.026). The time to analgesics prescription was 116.6 minutes (standard deviation 225.6) in 2013 and 64 minutes (standard deviation 75.5) in 2014 for all extremity injuries. The pain scoring increased from 1.4% to 51.6%. ED-based quality improvement activities including education and change of pain score documentation can improve the rate of analgesic prescription and time to prescription for patients with extremity injury in the ED.

Small studies of variable quality suggest that massage therapy may relieve pain and other symptoms. To evaluate the efficacy of massage for decreasing pain and symptom distress and improving quality of life among persons with advanced cancer. Multisite, randomized clinical trial. Population-based Palliative Care Research Network. 380 adults with advanced cancer who were experiencing moderate-to-severe pain; 90% were enrolled in hospice. Six 30-minute massage or simple-touch sessions over 2 weeks. Primary outcomes were immediate (Memorial Pain Assessment Card, 0- to 10-point scale) and sustained (Brief Pain Inventory [BPI], 0- to 10-point scale) change in pain. Secondary outcomes were immediate change in mood (Memorial Pain Assessment Card) and 60-second heart and respiratory rates and sustained change in quality of life (McGill Quality of Life Questionnaire, 0- to 10-point scale), symptom distress (Memorial Symptom Assessment Scale, 0- to 4-point scale), and analgesic medication use (parenteral morphine equivalents [mg/d]). Immediate outcomes were obtained just before and after each treatment session. Sustained outcomes were obtained at baseline and weekly for 3 weeks. 298 persons were included in the immediate outcome analysis and 348 in the sustained outcome analysis. A total of 82 persons did not receive any allocated study treatments (37 massage patients, 45 control participants). Both groups demonstrated immediate improvement in pain (massage, -1.87 points [95% CI, -2.07 to -1.67 points]; control, -0.97 point [CI, -1.18 to -0.76 points]) and mood (massage, 1.58 points [CI, 1.40 to 1.76 points]; control, 0.97 point [CI, 0.78 to 1.16 points]). Massage was superior for both immediate pain and mood (mean difference, 0.90 and 0.61 points, respectively; P < 0.001). No between-group mean differences occurred over time in sustained pain (BPI mean pain, 0.07 point [CI, -0.23 to 0.37 points]; BPI worst pain, -0.14 point [CI, -0.59 to 0.31 points]), quality of life (Mc

Objective To compare the effects of 4 months of isolated lumbar resistance exercise and total body resistance exercise on walking performance in obese, older adults with chronic low back pain. A secondary analysis examined whether responsiveness to training modulated walking improvement. Design Randomized, controlled trial. Setting Research laboratory affiliated with tertiary care facility. Methods and Intervention Participants (N = 49; 60–85 years) were randomized into a 4-month resistance exercise intervention (TOTRX), lumbar extensor exercise intervention (LEXT), or a control group (CON). Main Outcome Measurements Walking performance, maximal low back strength and leg strength, and average resting and low back pain severity score (from an 11-point numerical pain rating scale; NRSpain) were collected at baseline and month 4. Results The TOTRX and LEXT improved lumbar extensor strength relative to CON and the TOTRX (P < .05). NRSpain scores at month 4 were lowest in the TOTRX group compared with the LEXT and CON groups, respectively (2.0 ± 1.7 points vs 3.7 ± 2.6 points and 4.6 ± 2.4 points; P < .006). A total of 53% and 67% of participants in the TOTRX and LEXT groups were responders who made lumbar extensor strength gains that achieved ≥20% greater than baseline values. Although the TOTRX demonstrated the greatest improvement in walking endurance among the intervention groups, this did not reach significance (10.1 ± 12.2% improvement in TOTRX vs 7.4 ± 30.0% LEXT and −1.7 ± 17.4% CON; P = .11). Gait speed increased most in the TOTRX (9.0 ± 13.5%) compared with the LEXT and CON groups (P < .05). The change in lumbar extensor strength explained 10.6% of the variance of the regression model for the change in walking endurance (P = .024). Conclusions The use of LEXT and TOTRX produced similar modest improvements in patients’ walking endurance. Lumbar extensor strength gain compared with leg strength gain is a moderate but important contributor to

In the Republic of Georgia, the incidence and prevalence of cancer are increasing, signifying a growing need for palliative care and pain relief, including with controlled opioid medicines. As a signatory to the Single Convention, the Georgian government has a responsibility to ensure the adequate availability of controlled medicines for medical purposes; however, the consumption of morphine is very low, suggesting a high occurrence of unrelieved pain. In Georgia, palliative care development began in the 2000s including the adoption of a policy document in 2005, the creation of the National Palliative Care Coordinator in 2006, and important changes in Georgian legislation in 2007 and 2008, which served to lay a foundation for improving opioid availability. In 2008, a neurologist from the Sarajishvili Institute of Neurology and Neurosurgery in Tbilisi, and member of the Georgia National Association for Palliative Care, was selected to be an International Pain Policy Fellow to focus on improving opioid availability. Working with colleagues, government officials, and international experts, the Fellow contributed to several improvements to opioid availability, such as 1) positive changes to opioid prescribing legislation, 2) clarification of legislative terminology regarding dependence syndrome, 3) initiating the importation of both sustained-release and immediate-release oral morphine, and 4) improvements in the availability of sustained-release morphine. Despite these varied achievements, morphine consumption remains low in Georgia relative to the estimated amounts needed. The Fellow is continuing to study and understand the barriers that are impeding physician's prescription of opioids and patient's acceptance of them.

Pain in children--are we accomplishing the optimal pain treatment?

Lundeberg, Stefan

2015-01-01

Morphine, paracetamol and local anesthetics have for a long time been the foremost used analgesics in the pediatric patient by tradition but not always enough effective and associated with side effects. The purpose with this article is to propose alternative approaches in pain management, not always supported up by substantial scientific work but from a combination of science and clinical experience in the field. The scientific literature has been reviewed in parts regarding different aspects of pain assessment and analgesics used for treatment of diverse pain conditions with focus on procedural and acute pain. Clinical experience has been added to form the suggested improvements in accomplishing an improved pain management in pediatric patients. The aim with pain management in children should be a tailored analgesic medication with an individual acceptable pain level and optimal degree of mobilization with as little side effects as possible. Simple techniques of pain control are as effective as and complex techniques in pediatrics but the technique used is not of the highest importance in achieving a good pain management. Increased interest and improved education of the doctors prescribing analgesics is important in accomplishing a better pain management. The optimal treatment with analgesics is depending on the analysis of pain origin and analgesics used should be adjusted thereafter. A multimodal treatment regime is advocated for optimal analgesic effect. © 2014 John Wiley & Sons Ltd.

Chronic joint pain is a major cause of pain and disability. Exercise and self-management have short-term benefits, but few studies follow participants for more than 6 months. We investigated the long-term (up to 30 months) clinical and cost effectiveness of a rehabilitation program combining self-management and exercise: Enabling Self-Management and Coping of Arthritic Knee Pain Through Exercise (ESCAPE-knee pain). In this pragmatic, cluster randomized, controlled trial, 418 people with chronic knee pain (recruited from 54 primary care surgeries) were randomized to usual care (pragmatic control) or the ESCAPE-knee pain program. The primary outcome was physical function (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] function), with a clinically meaningful improvement in physical function defined as a ≥15% change from baseline. Secondary outcomes included pain, psychosocial and physiologic variables, costs, and cost effectiveness. Compared to usual care, ESCAPE-knee pain participants had large initial improvements in function (mean difference in WOMAC function -5.5; 95% confidence interval [95% CI] -7.8, -3.2). These improvements declined over time, but 30 months after completing the program, ESCAPE-knee pain participants still had better physical function (difference in WOMAC function -2.8; 95% CI -5.3, -0.2); lower community-based health care costs (£-47; 95% CI £-94, £-7), medication costs (£-16; 95% CI £-29, £-3), and total health and social care costs (£-1,118; 95% CI £-2,566, £-221); and a high probability (80-100%) of being cost effective. Clinical and cost benefits of ESCAPE-knee pain were still evident 30 months after completing the program. ESCAPE-knee pain is a more effective and efficient model of care that could substantially improve the health, well-being, and independence of many people, while reducing health care costs.

We retrospectively evaluated the effectiveness of prolotherapy in resolving pain, stiffness, and crepitus, and improving physical activity in consecutive chondromalacia patients from February 2008 to September 2009. Sixty-nine knees that received prolotherapy in 61 patients (33 female and 36 male) who were 18-82 years old (average, 47.2 years) were enrolled. Patients received 24 prolotherapy injections (15% dextrose, 0.1% procaine, and 10% sarapin) with a total of 40 cc in the anterior knee. At least 6 weeks after their last prolotherapy session, patients provided self-evaluation of knee pain upon rest, activities of daily living (ADL) and exercise, range of motion (ROM), stiffness, and crepitus. Symptom severity, sustained improvement of symptoms, number of pain pills needed, and patient satisfaction before treatment and improvement after treatment were recorded. Following prolotherapy, patients experienced statistically significant decreases in pain at rest, during ADL, and exercise. Stiffness and crepitus decreased after prolotherapy, and ROM increased. Patients reported improved walking ability and exercise ability after prolotherapy. For daily pain level, ROM, daily stiffness, crepitus, and walking and exercise ability, sustained improvement of over 75% was reported by 85% of patients. Fewer patients required pain medication. No side effects of prolotherapy were noted. The average length of time from last prolotherapy session was 14.7 months (range, 6 months to 8 years). Only 3 of 16 knees were still recommended for surgery after prolotherapy. Prolotherapy ameliorates chondromalacia patella symptoms and improves physical ability. Patients experience long-term improvement without requiring pain medications. Prolotherapy should be considered a first-line, conservative therapy for chondromalacia patella.

Pain is a syndrome characterized by several neurophysiological changes including that of the autonomic nervous system. Chronic low back pain (LBP) is a major health problem and is a frequent reason for using unconventional therapies especially acupuncture. This study was conducted to evaluate the autonomic status and pain profile in chronic LBP patients and to observe the effect of electro acupuncture therapy. Chronic LBP patients (n=60) were recruited from the Department of Orthopaedics, GTB Hospital, Delhi. Age and sex matched healthy volunteers were selected as controls (n=30). Following a written consent, LBP patients were randomly allocated into two study groups - Group A received 10 sittings of electro acupuncture, on alternate days, at GB and UB points selected for back pain, while the Group B received a conventional drug therapy in the form of oral Valdecoxib together with supervised physiotherapy. Controls were assessed once while the patients were assessed twice, before and after completion of the treatment program (3 weeks). The autonomic status was studied with non-invasive cardiovascular autonomic function tests which included E: I ratio, 30:15 ratio, postural challenge test and sustained handgrip test. Pain intensity was measured with the visual analogue scale (VAS) and the global perceived effect (GPE). Statistical analysis was performed using repeated measure's ANOVA with Tukey's test. Pain patients showed a significantly reduced vagal tone and increased sympathetic activity as compared to the controls (P<0.05 to P<0.001 in different variables). Following treatment, both the study groups showed a reduction in vagal tone together with a decrease in the sympathetic activity. There was also a considerable relief of pain in both groups, however, the acupuncture group showed a better response (P<0.01). We conclude that there is autonomic dysfunction in chronic LBP patients. Acupuncture effectively relieves the pain and improves the autonomic status and

Pancreatic cancer is often accompanied by severe abdominal or back pain. It's the first study to evaluate the analgesic effect of electroacupuncture on pancreatic cancer pain. A randomized controlled trial compared electroacupuncture with control acupuncture using the placebo needle. Sixty patients with pancreatic cancer pain were randomly assigned to the electroacupuncture group (n = 30) and the placebo control group (n = 30). Patients were treated on Jiaji (Ex-B2) points T8-T12 bilaterally for 30 min once a day for 3 days. Pain intensity was assessed with numerical rated scales (NRS) before the treatment (Baseline), after 3 treatments, and 2 days follow-up. Baseline characteristics were similar in the two groups. After 3 treatment, pain intensity on NRS decreased compared with Baseline (-1.67, 95% confidence interval [CI] -1.46 to -1.87) in the electroacupuncture group; there was little change (-0.13, 95% CI 0.08 to -0.35) in control group; the difference between two groups was statistically significant (P < 0.001). Follow-up also found a significant reduction in pain intensity in the electroacupuncture group compared with the control group (P < 0.001). Electroacupuncture was an effective treatment for relieving pancreatic cancer pain. Copyright © 2013 IAP and EPC. Published by Elsevier B.V. All rights reserved.

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.

In this preliminary trial we investigated the effects of dry cupping, an ancient method for treating pain syndromes, on patients with chronic non-specific neck pain. Sensory mechanical thresholds and the participants' self-reported outcome measures of pain and quality of life were evaluated. Fifty patients (50.5 ± 11.9 years) were randomised to a treatment group (TG) or a waiting-list control group (WL). Patients in the TG received a series of 5 cupping treatments over a period of 2 weeks; the control group did not. Self-reported outcome measures before and after the cupping series included the following: Pain at rest (PR) and maximal pain related to movement (PM) on a 100-mm visual analogue scale (VAS), pain diary (PD) data on a 0-10 numeric rating scale (NRS), Neck Disability Index (NDI), and health-related quality of life (SF-36). In addition, the mechanical-detection thresholds (MDT), vibration-detection thresholds (VDT), and pressure-pain thresholds (PPT) were determined at pain-related and control areas. Patients of the TG had significantly less pain after cupping therapy than patients of the WL group (PR: Δ-22.5 mm, p = 0.00002; PM: Δ-17.8 mm, p = 0.01). Pain diaries (PD) revealed that neck pain decreased gradually in the TG patients and that pain reported by the two groups differed significantly after the fifth cupping session (Δ-1.1, p = 0.001). There were also significant differences in the SF-36 subscales for bodily pain (Δ13.8, p = 0.006) and vitality (Δ10.2, p = 0.006). Group differences in PPT were significant at pain-related and control areas (all p < 0.05), but were not significant for MDT or VDT. A series of five dry cupping treatments appeared to be effective in relieving chronic non-specific neck pain. Not only subjective measures improved, but also mechanical pain sensitivity differed significantly between the two groups, suggesting that cupping has an influence on functional pain processing. The trial was registered at clinicaltrials

Integration of Specialized Pain Control Services in Palliative Care: A Nationwide Web-based Survey.

Pain control is an important part of palliative care (PC), and conventional analgesics do not provide adequate pain relief to all patients. Many patients present with complex pain syndromes that require interventional pain control measures usually deployed by pain specialists. There is adequate integration of specialized pain control services with PC elsewhere, but information about the same in our country is lacking. An internet survey was conducted among palliative specialists regarding the need and availability of pain specialists for their patients suffering from complex pain syndromes. Their attitude toward integrating specialized pain control services in their practice was also explored. Majority of palliative physicians came across situations where specialists in pain would control the patients' pain better. There was a poor availability of such services, and when available, the cost was significant. It is heartening to note that though there is poor integration of specialized pain control services with palliation, palliative physicians acknowledge the need for pain specialists and their techniques for providing pain relief for their patients. Effective pain control is needed in palliation, barriers however exist, and there is a need to make pain specialists and interventional techniques more freely available.

Pain catastrophizing (PC) is associated with more severe and disabling migraine attacks. However, factors that moderate this relationship are unknown. Failure of inhibitory control (IC), or the ability to suppress automatic or inappropriate responses, may be one such factor given previous research showing a relationship between higher PC and lower IC in non-migraine samples, and research showing reduced IC in migraine. Therefore, we examined whether lower IC interacts with increased PC to predict greater migraine severity as measured by pain intensity, attack frequency, and duration. Women (n = 105) aged 18-50 years old (M = 38.0 ± 1.2) with overweight/obesity and migraine who were seeking behavioral treatment for weight loss and migraine reduction completed a 28-day smartphone-based headache diary assessing migraine headache severity. Participants then completed a modified computerized Stroop task as a measure of IC and self-report measures of PC (Pain Catastrophizing Scale [PCS]), anxiety, and depression. Linear regression was used to examine independent and joint associations of PC and IC with indices of migraine severity after controlling for age, body mass index (BMI) depression, and anxiety. Participants on average had BMI of 35.1 ± 6.5 kg/m 2 and reported 5.3 ± 2.6 migraine attacks (8.3 ± 4.4 migraine days) over 28 days that produced moderate pain intensity (5.9 ± 1.4 out of 10) with duration of 20.0 ± 14.2 h. After adjusting for covariates, higher PCS total (β = .241, SE = .14, p = .03) and magnification subscale (β = .311, SE = .51, p < .01) scores were significant independent correlates of longer attack duration. IC interacted with total PCS (β = 1.106, SE = .001, p = .03) rumination (β = 1.098, SE = .001, p = .04), and helplessness (β = 1.026, SE = .001, p = .04) subscale scores to predict headache pain intensity, such that the association between PC

We conducted a double-blind, placebo-controlled, crossover study evaluating the analgesic efficacy of vaporized cannabis in subjects, the majority of whom were experiencing neuropathic pain despite traditional treatment. Thirty-nine patients with central and peripheral neuropathic pain underwent a standardized procedure for inhaling either medium dose (3.53%), low dose (1.29%), or placebo cannabis with the primary outcome being VAS pain intensity. Psychoactive side-effects, and neuropsychological performance were also evaluated. Mixed effects regression models demonstrated an analgesic response to vaporized cannabis. There was no significant difference between the two active dose groups’ results (p>0.7). The number needed to treat (NNT) to achieve 30% pain reduction was 3.2 for placebo vs. low dose, 2.9 for placebo vs. medium dose, and 25 for medium vs. low dose. As these NNT are comparable to those of traditional neuropathic pain medications, cannabis has analgesic efficacy with the low dose being, for all intents and purposes, as effective a pain reliever as the medium dose. Psychoactive effects were minimal and well-tolerated, and neuropsychological effects were of limited duration and readily reversible within 1–2 hours. Vaporized cannabis, even at low doses, may present an effective option for patients with treatment-resistant neuropathic pain. PMID:23237736

A controlled comparison of emotional reactivity and physiological response in masticatory muscle pain patients.

Schmidt, John E; Carlson, Charles R

2009-01-01

To investigate (1) differences in heart rate variability (HRV) indices between masticatory muscle pain (MMP) patients and pain-free controls at rest, during a stressor condition, and during a post-stressor recovery period, and (2) factors including psychological distress, social environment, and family-of-origin characteristics in the MMP sample compared to a pain-free matched control sample. Physiological activation and emotional reactivity were assessed in 22 MMP patients and 23 controls during baseline, stressor, and recovery periods. Physiological activity was assessed with frequency domain HRV indices. Emotional reactivity was assessed with the Emotional Assessment Scale. Analytic strategy began with overall 2 x 3 multivariate analyses of variance on physiological data followed by focused contrasts to test specific hypotheses regarding physiological and emotional status. Hypothesized differences between study groups on psychological and social-environmental variables were compared with univariate analyses of variance. The MMP patients showed physiological activation during the baseline period and significantly more physiological activation during the recovery period compared to the controls. This pattern was also present in emotional reactivity between the groups. The emotional and physiological differences between the groups across study periods were more pronounced in pain patients reporting a traumatic stressor. These results provide further evidence of physiological activation and emotional responding in MMP patients that differentiates them from matched pain-free controls. The use of HRV indices to measure physiological functioning quantifies the degree of sympathetic and parasympathetic activation. Study results suggest the use of these HRV indices may improve understanding of the role of excitatory and inhibitory mechanisms in patients with MMP conditions.

Extracorporeal shock wave therapy (ESWT) has been used to reduce pain in patients with various musculoskeletal diseases and wounds. We investigated the effect of ESWT on scar pain after complete wound epithelialization in burn patients. A prospective, single-blind, placebo-controlled study was conducted from February 2014 to 2015. Forty patients with burn scar pain despite standard therapy (medication, physical therapy, and burn rehabilitation massage therapy) were randomized into ESWT or control (sham ESWT) groups. ESWT was administered at 100 impulses/cm (0.05-0.15 mJ/mm) once per week for 3 weeks. The treatment effects were assessed using the numerical rating scale (NRS), pain threshold, Nirschl pain phase system, and Roles and Maudsley scores. The characteristics of patients between the 2 study groups were balanced (P >0.05) for age, sex, and total burn surface area (%). In both groups, the NRS, pain threshold (Ib/cm), and Nirschl pain phase system values significantly improved (P <0.05) after 3 sessions of ESWT or sham therapy, and there were significant differences between the 2 groups in terms of these 3 variables (P <0.001, P <0.001, P = 0.013, respectively). The Roles and Maudsley scores significantly improved; among 20 patients, 17 reported a score of poor (85%) and 3 reported fair (15%) before ESWT, whereas 3 reported poor (15%), 8 reported fair (40%), 5 reported good (25%), and 4 reported excellent (20%) after ESWT (P = 0.004). The scores did not improve in the control group (P = 0.128). ESWT significantly reduced scar pain in burn patients after wound recovery.

Balance ability and postural stability among patients with painful shoulder disorders and healthy controls

PubMed Central

2013-01-01

Background In therapeutic settings, patients with shoulder pain often exhibit deficient coordinative abilities in their trunk and lower extremities. The aim of the study was to investigate 1) if there is a connection between shoulder pain and deficits in balance ability and postural stability, 2) if pain intensity is related to balance ability and postural stability, and 3) if there is a connection between body mass index (BMI) and balance ability and postural stability. Methods In this case–control study, patients (n = 40) with pathological shoulder pain (> 4 months) were matched with a healthy controls (n = 40) and were compared with regard to their balance ability and postural stability. Outcome parameters were postural stability, balance ability and symmetry index which were measured using the S3-Check system. In addition, the influence of shoulder pain intensity and BMI on the outcome parameters was analysed. Results Patients with shoulder pain showed significantly worse results in measurements of postural stability right/left (p < 0.01) and front/back (p < 0.01) as well as balance ability right/left (p = 0.01) and front/back (p < 0.01) compared to healthy controls. There were no significant group differences with regard to symmetry index. However, there was a significant (p < 0.01) symmetry shift towards the affected side within the shoulder pain group. There was no correlation between pain intensity and measurements of balance ability or postural stability. Likewise, no correlation between BMI and deficiencies in balance ability and postural stability was established. Conclusions Patients with pathological shoulder pain (> 4 months) have deficiencies in balance ability and postural stability; however the underlying mechanisms for this remain unclear. Neither pain intensity nor BMI influenced the outcome parameters. Patients with shoulder pain shift their weight to the affected side. Further research is needed to determine if

Fibromyalgia (FM) is a clinical syndrome characterised by widespread musculoskeletal pain, chronic fatigue, cognitive deficits, and sleep and mood disorders. The effectiveness of most pharmacological treatments is limited, and there is a need for new, effective and well-tolerated therapies. It has recently been shown that transcranial direct-current stimulation (tDCS) of the motor cortex reduces pain, and that tDCS of the dorso-lateral prefrontal cortex (DLPFC) improves anxiety, depression and cognitive impairment in FM patients. The new technique of transcranial random noise stimulation (tRNS) using randomly changing alternating currents has very recently been shown to improve working memory and pain in limited series of patients with FM or neuropathic pain. The aim of this study was to investigate the clinical effects of primary motor cortex (M1) tRNS in FM patients. Twenty female FM patients aged 26-67 years were randomised to undergo active (real) or placebo (sham) tRNS sessions on five days a week (Monday-Friday) for two weeks. Each patient was evaluated before and after treatment using a visual analogue scale (VAS), the Fibromyalgia Impact Questionnaire (FIQ), the Hospital Anxiety and Depression Scale (HADS), the Trail Making Test (TMT), the Rey Auditory Verbal Learning Test (RAVLT), the Forward and Backward Digit Span test, and the FAS verbal fluency test. In comparison with sham treatment, active tRNS of M1 induced a general improvement in the clinical picture of FM, with a significant reduction in pain, depression, anxiety and FIQ scores and a significant improvement in TMT (A), RAVLT and FAS scores. These findings suggest that tRNS of M1 can be very effective in relieving FM symptoms. Unlike motor cortex tDCS, it seems to counteract both pain and cognitive disturbances, possibly because the invoked mechanism of stochastic resonance synchronises neural firing and thus leads to more widespread and lasting effects.

Low back pain affects the person's ability to keep balance, especially in challenging conditions. The purpose of this study was to determine the immediate effects of Pilates exercises on postural sway and dynamic balance of young individuals with non-specific low back pain. Controlled laboratory design. Forty-six participants with non-specific low back pain were randomized to a Pilates (n=23, 10 males; age: 21.8±3.2years) and a control group (n=23, 9 males; age: 22.8±3.6years). Postural sway was assessed with a force platform and dynamic balance with the Star Excursion Balance Test, before and after the intervention or rest period. To assess postural sway, participants stood still on an unstable surface set on the force plate for 90s, with eyes closed. The intervention lasted 20min and consisted on four Pilates exercises: single leg stretch (level 1), pelvic press (level 1), swimming (level 1) and kneeling opposite arm and leg reach. At baseline, no differences were found between groups. The Pilates group improved in all the postural sway values (area of CoP: 11.5±3.4 to 9.7±2.7cm 2 , p=0.002 and CoP velocity: 2.8±0.6 to 2.3±0.5cm/s, p<0.001) and in the Star Excursion Balance Test. Control group only improved in CoP velocity, however, this improvement was significantly inferior compared to the Pilates group. Pilates exercises immediately improved postural sway and dynamic balance in young adults with non-specific low back pain. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although hydrocodone-acetaminophen is commonly used for pain control in first-trimester abortion, the efficacy of oral opioids for decreasing pain has not been established. Our objective was to estimate the effect of hydrocodone-acetaminophen on patient pain perception during first-trimester surgical abortion. We conducted a randomized, double-blinded, placebo-controlled trial. Patients (before 11 weeks of gestation) received standard premedication (ibuprofen and lorazepam) and a paracervical block with the addition of 10 mg hydrocodone and 650 mg acetaminophen or placebo 45-90 minutes before surgical abortion. A sample size of 120 was calculated to provide 80% power to show a 15-mm difference (α=0.05) in the primary outcome of pain with uterine aspiration (100-mm visual analog scale). Secondary outcomes were pain at additional time points, satisfaction, side effects, adverse events, and need for additional pain medications. There were no significant differences in demographics or baseline pain between groups. There were no differences in pain scores between patients receiving hydrocodone-acetaminophen compared with placebo during uterine aspiration (65.7 mm compared with 63.2 mm, P=.59) or other procedural time points. There were no differences in satisfaction or need for additional pain medications. Patients who received hydrocodone-acetaminophen had more postoperative nausea than those receiving placebo (P=.03) when controlling for baseline nausea. No medication-related adverse events were noted. Hydrocodone-acetaminophen does not decrease pain during first-trimester abortion and may increase postoperative nausea.

We retrospectively evaluated the effectiveness of prolotherapy in resolving pain, stiffness, and crepitus, and improving physical activity in consecutive chondromalacia patients from February 2008 to September 2009. Sixty-nine knees that received prolotherapy in 61 patients (33 female and 36 male) who were 18–82 years old (average, 47.2 years) were enrolled. Patients received 24 prolotherapy injections (15% dextrose, 0.1% procaine, and 10% sarapin) with a total of 40 cc in the anterior knee. At least 6 weeks after their last prolotherapy session, patients provided self-evaluation of knee pain upon rest, activities of daily living (ADL) and exercise, range of motion (ROM), stiffness, and crepitus. Symptom severity, sustained improvement of symptoms, number of pain pills needed, and patient satisfaction before treatment and improvement after treatment were recorded. Following prolotherapy, patients experienced statistically significant decreases in pain at rest, during ADL, and exercise. Stiffness and crepitus decreased after prolotherapy, and ROM increased. Patients reported improved walking ability and exercise ability after prolotherapy. For daily pain level, ROM, daily stiffness, crepitus, and walking and exercise ability, sustained improvement of over 75% was reported by 85% of patients. Fewer patients required pain medication. No side effects of prolotherapy were noted. The average length of time from last prolotherapy session was 14.7 months (range, 6 months to 8 years). Only 3 of 16 knees were still recommended for surgery after prolotherapy. Prolotherapy ameliorates chondromalacia patella symptoms and improves physical ability. Patients experience long-term improvement without requiring pain medications. Prolotherapy should be considered a first-line, conservative therapy for chondromalacia patella. PMID:24596471

Objectives Several recent studies report the presence of a specific EEG pattern named Thalamocortical Dysrhythmia (TCD) in patients with severe chronic neurogenic pain. This is of major interest since so far no neuroscientific indicator of chronic pain could be identified. We investigated whether a TCD-like pattern could be found in patients with moderate chronic back pain, and we compared patients with neuropathic and non-neuropathic pain components. We furthermore assessed the presence of psychopathology and the degree of psychological functioning and examined whether the strength of the TCD-related EEG markers is correlated with psychological symptoms and pain ratings. Design Controlled clinical trial with age and sex matched healthy controls. Methods Spontaneous EEG was recorded in 37 back pain patients and 37 healthy controls. Results We were not able to observe a statistically significant TCD effect in the EEG data of the whole patient group, but a subsample of patients with evidence for root damage showed a trend in this direction. Pain patients showed markedly increased psychopathology. In addition, patients' ratings of pain intensity within the last 1 to 12 months showed strong correlations with EEG power, while psychopathology was correlated to the peak frequency. Conclusion Out of several possible interpretations the most likely conclusion is that only patients with severe pain as well as root lesions with consecutive thalamic deafferentation develop the typical TCD pattern. Our primary method of defining ‘neuropathic pain’ could not reliably determine if such a deafferentation was present. Nevertheless the analysis of a specific subsample as well as correlations between pain ratings, psychopathology and EEG power and peak frequency give some support to the TCD concept.

Low back pain (LBP) is the leading cause of disability worldwide. Of those patients who present to primary care with acute LBP, 40% continue to report symptoms 3 months later and develop chronic LBP. Although it is possible to identify these patients early, effective interventions to improve their outcomes are not available. This double-blind (participant/outcome assessor) randomised controlled trial will investigate the efficacy of a brief educational approach to prevent chronic LBP in 'at-risk' individuals. Participants will be recruited from primary care practices in the Sydney metropolitan area. To be eligible for inclusion participants will be aged 18-75 years, with acute LBP (<4 weeks' duration) preceded by at least a 1 month pain-free period and at-risk of developing chronic LBP. Potential participants with chronic spinal pain and those with suspected serious spinal pathology will be excluded. Eligible participants who agree to take part will be randomly allocated to receive 2×1 h sessions of pain biology education or 2×1 h sessions of sham education from a specially trained study physiotherapist. The study requires 101 participants per group to detect a 1-point difference in pain intensity 3 months after pain onset. Secondary outcomes include the incidence of chronic LBP, disability, pain intensity, depression, healthcare utilisation, pain attitudes and beliefs, global recovery and recurrence and are measured at 1 week post-intervention, and at 3, 6 and 12 months post LBP onset. Ethical approval was obtained from the University of New South Wales Human Ethics Committee in June 2013 (ref number HC12664). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conference meetings. https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12612001180808.

Neck pain is associated with several alterations in neck motion and motor control, but most of the findings are based on cross-sectional studies. The aim of this study was to investigate associations between changes in neck motion and motor control, and changes in neck pain and disability in physiotherapy patients during a course of treatment. Prospective cohort study. Subjects with non-specific neck pain (n = 71) participated in this study. Neck flexibility, joint position error (JPE), head steadiness, trajectory movement control and postural sway were recorded before commencement of physiotherapy (baseline), at 2 weeks, and at 2 months. Numerical Rating Scale and Neck Disability Index were used to measure neck pain and disability at the day of testing. To analyze within subjects effects in neck motion and motor control, neck pain, and disability over time we used fixed effects linear regression analysis. Changes in neck motion and motor control occurred primarily within 2 weeks. Reduction in neck pain was associated with increased cervical range of motion in flexion-/extension and increased postural sway when standing with eyes open. Decreased neck disability was associated with some variables for neck flexibility and trajectory movement control. Cervical range of motion in flexion-/extension was the only variable associated with changes in both neck pain and neck disability. This study shows that few of the variables for neck motion and motor control were associated with changes neck pain and disability over a course of 2 months with physiotherapy treatment.

Many women experience pain during hysterosalpingogram (HSG). This prospective, randomized, double-blinded, placebo-controlled study assessed whether the use of benzocaine spray during HSG is associated with reduced pain as compared with placebo. Thirty women presenting for HSG were enrolled and randomized to either benzocaine or saline spray. Treatment groups were similar in age, race, parity, pre-procedure oral analgesic use and history of dysmenorrhoea and/or chronic pelvic pain. Median change in pain score from baseline to procedure was 50.6 mm (−7.4 to 98.8 mm) in the benzocaine group and 70.4 mm (19.8 to 100 mm) in the placebo group. There was no difference between groups after adjusting for history of dysmenorrhoea. There was no difference in resolution of pain in benzocaine versus placebo groups at 5 min post procedure – median pain score difference – 11.1 (−90.1 to 18.5) versus −37.0 (−100 to 1.2) – or at 30 min post procedure. Satisfaction scores did not differ by treatment and did not correlate with pain score during the procedure (rho = 0.005). The use of benzocaine spray does not significantly improve pain relief during HSG nor does it hasten resolution of pain post HSG. Of interest, patient satisfaction was not correlated with pain.

In this sham-controlled study, 53 patients received 10 sessions of acupuncture treatment over 5 weeks to investigate the effects of acupuncture on the pain and quality of life of patients with osteoporosis. The results showed significant favorable effects of verum acupuncture on quality of life. Both interventions showed sustained and clinically relevant effects on pain. Standard analgesic treatment is associated with adverse events in patients with osteoporosis, especially elderly and/or comorbid patients. As acupuncture has gained widespread acceptance as a complementary treatment modality with few side effects, the aim of this study was to evaluate the effects of acupuncture on the pain and quality of life of patients with osteoporosis. In total, 53 patients with vertebral compression fractures, osteoporosis-associated spinal deformities, and resultant pain were randomly allocated to the verum acupuncture with deep needling of specific points following the principles of traditional Chinese medicine (n = 29) or control acupuncture group with superficial needling of non-acupuncture points (n = 24). All patients received 10 sessions of standardized verum or control acupuncture treatment over 5 weeks. Pain (VAS score 1-100) and quality of life (QUALEFFO-41) were measured at the start of treatment (T0), before each acupuncture session (T1), and at 1 (T2) and 3 months (T3) post-treatment. Both acupuncture treatments significantly reduced activity-related pain and pain at rest over time. The verum acupuncture group experienced a significantly greater reduction in mean pain intensity at rest than the control group. In the control group, quality of life improved only temporarily post-treatment (T2) and slightly declined at the end of the follow-up period (T3). In contrast, patients in the verum acupuncture group experienced continuous and significant improvements in quality of life up to 3 months after treatment (T3). Both types of acupuncture were equally

The unbearable mental pain experience is recognized as a key antecedent of suicidal behavior. We aimed to examine the precise nature of the mental pain among medically serious suicide attempters (MSSAs), a population closely resembling those who died by suicide. We evaluated various factors of mental pain from the Orbach and Mikulincer Mental Pain Scale, as well as medical lethality and suicide intent. MSSAs were higher than non-MSSAs and psychiatric controls for Irreversibility of pain. Moreover, Emptiness predicted medical lethality, while Cognitive Confusion negatively predicted suicide intent level, controlling for hopelessness and depression. high sense of Irreversibility of pain as well as high Emptiness and low Cognitive Confusion are important risk factors for more severe suicidal behavior. Implications for identification of at-risk groups for suicide as well as for suicide prevention and treatment of suicidal individuals are discussed.

Can training in empathetic validation improve medical students' communication with patients suffering pain? A test of concept.

Patient-centered, empathetic communication has been recommended as a means for improving the health care of patients suffering pain. However, a problem has been training health care providers since programs may be time-consuming and difficult to learn. Validation, a form of empathetic response that communicates that what a patient experiences is accepted as true, has been suggested as an appropriate method for improving communication with patients suffering pain. We study the immediate effects of providing medical students with a 2-session (45-minute duration each) program in validation skills on communication. A one group, pretest vs posttest design was employed with 22 volunteer medical students. To control patient variables, actors simulated 1 of 2 patient scenarios (randomly provided at pretest and posttest). Video recordings were blindly evaluated. Self-ratings of validation and satisfaction were also employed. Observed validation responses increased significantly after training and corresponded to significant reductions in invalidating responses. Both the patient simulators and the medical students were significantly more satisfied after the training. We demonstrated that training empathetic validation results in improved communication thus extending previous findings to a medical setting with patients suffering pain. Our results suggest that it would be feasible to provide validation training for health care providers and this warrants further investigation in controlled studies.

Traditional Chinese medication (TCM) has analgesic and anti-inflammatory effects in patients with knee osteoarthritis (OA). We conducted the first systematic review of the best quantitative and qualitative evidence currently available in order to evaluate the effectiveness of TCM in relieving pain in knee OA. A comprehensive literature search was conducted using three English and four Chinese biomedical databases from their inception through March 1, 2015. We included randomized controlled trials of TCM for knee OA with intervention durations of at least two weeks. The effects of TCM on pain and other clinical symptoms were measured with the visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The total effectiveness rate, which was used to assess overall pain, physical performance and wellness, was also measured. Two researchers independently extracted data on study design, population characteristics, duration, intervention, outcomes, risk of bias, and primary results. We performed a random-effects meta-analysis when appropriate. We also explored factors that could explain the heterogeneity by conducting subgroup and meta-regression analyses. Twenty-three studies, totaling 2362 subjects, met the eligibility criteria. Treatments were formulated with an average of 8 Chinese herbs and were prescribed based on the traditional Chinese diagnostic method of syndrome differentiation. The mean treatment duration was seven weeks, with oral administration occurring one to three times a day. Compared with non-steroidal anti-inflammatory drugs and intra-articular hyaluronate injections, 18 of the studies showed significantly improved VAS pain scores (Mean Difference [MD] [Formula: see text] 0.56; 95% confidence interval [CI], 0.18 to 0.94; [Formula: see text]), six of the studies showed significantly improved WOMAC pain subscale scores (MD [Formula: see text] 2.23; 95% CI, 0.56 to 3.91; [Formula: see text]), and 16 of the trials

To evaluate the effect of three types of exercise intervention in patients with patellofemoral pain and to verify the contributions of each intervention to pain control, function, and lower extremity kinematics. A randomized controlled, single-blinded trial was conducted. Forty women with patellofemoral pain were randomly allocated into four groups: hip exercises, quadriceps exercises, stretching exercises and a control group (no intervention). Pain (using a visual analog scale), function (using the Anterior Knee Pain Scale), hip and quadriceps strength (using a handheld isometric dynamometer) and measuring lower limb kinematics during step up and down activities were evaluated at baseline and 8 weeks post intervention. All treatment groups showed significant improvements on pain and Anterior Knee Pain Scale after intervention with no statistically significant differences between groups except when compared to the control group. Only hip and quadriceps groups demonstrated improvements in muscle strength and knee valgus angle during the step activities. Hip strengthening exercises were not more effective for pain relief and function compared to quadriceps or stretching exercises in females with patellofemoral pain. Only hip and quadriceps groups were able to decrease the incidence of dynamic valgus during step-down activity. This study was approved by Brazilian Clinical Trials Registry registration number: RBR-6tc7mj (http://www.ensaiosclinicos.gov.br/rg/RBR-6tc7mj/).

Study protocol: Improving patient choice in treating low back pain (IMPACT - LBP): A randomised controlled trial of a decision support package for use in physical therapy

PubMed Central

2011-01-01

Background Low back pain is a common and costly condition. There are several treatment options for people suffering from back pain, but there are few data on how to improve patients' treatment choices. This study will test the effects of a decision support package (DSP), designed to help patients seeking care for back pain to make better, more informed choices about their treatment within a physiotherapy department. The package will be designed to assist both therapist and patient. Methods/Design Firstly, in collaboration with physiotherapists, patients and experts in the field of decision support and decision aids, we will develop the DSP. The work will include: a literature and evidence review; secondary analysis of existing qualitative data; exploration of patients' perspectives through focus groups and exploration of experts' perspectives using a nominal group technique and a Delphi study. Secondly, we will carry out a pilot single centre randomised controlled trial within NHS Coventry Community Physiotherapy. We will randomise physiotherapists to receive either training for the DSP or not. We will randomly allocate patients seeking treatment for non specific low back pain to either a physiotherapist trained in decision support or to receive usual care. Our primary outcome measure will be patient satisfaction with treatment at three month follow-up. We will also estimate the cost-effectiveness of the intervention, and assess the value of conducting further research. Discussion Informed shared decision-making should be an important part of any clinical consultation, particularly when there are several treatments, which potentially have moderate effects. The results of this pilot will help us determine the benefits of improving the decision-making process in clinical practice on patient satisfaction.

2017-11-06

Local infiltrations and regional blocks have been some of the effective ways employed to manage and control post-operative pain. One of the limitations of administration of local anesthesia drugs in post-operative conditions is its inability to act for a longer period of time. Multi-vesicular liposomes made up of bupivacaine have been progressively used for their increased duration of action. Compared to bupivacaine HCL, local infiltration of liposomal bupivacaine have shown to have a significantly increase the duration and delay in peak plasma concentration. In this article, we attempt to compare liposomal bupivacaine and bupivacaine based on available clinical literatures. Liposomal bupivacaine has been demonstrated to have promising implications in post- operative pain control resulting in increased patient satisfaction; reduced hospital admission and opioid induced adverse events. Clinical studies have identified liposomal bupivacaine to be effective in delivering increased post-operative pain control. The purpose of this review is to give a comprehensive comparison between bupivacaine liposomal and conventional bupivacaine based on reported clinical trials. © Georg Thieme Verlag KG Stuttgart · New York.

There have been few large-scale, real world studies in Spain to assess change in pain and quality of life (QOL) outcomes in cancer patients with moderate to severe pain. This study aimed to assess changes on both outcomes after 3 months of usual care and to investigate factors associated with change in QoL. Large, multi-centre, observational study in patients with lung, head and neck, colorectal or breast cancer experiencing a first episode of moderate to severe pain while attending one of the participating centres. QoL was assessed using the EuroQol-5D questionnaire and pain using the Brief Pain Inventory (BPI). Instruments were administered at baseline and after 3 months of follow up. Multivariate analyses were used to assess the impact of treatment factors, demographic and clinical variables, pain and other symptoms on QoL scores. 1711 patients were included for analysis. After 3 months of usual care, a significant improvement was observed in pain and QoL in all four cancer groups (p<0.001). Effect sizes were medium to large on the BPI and EQ-5D Index and Visual Analogue Scale (VAS). Improvements were seen on the majority of EQ-5D dimensions in all patient groups, though breast cancer patients showed the largest gains. Poorer baseline performance status (ECOG) and the presence of anxiety/depression were associated with significantly poorer QOL outcomes. Improvements in BPI pain scores were associated with improved QoL. In the four cancer types studied, pain and QoL outcomes improved considerably after 3 months of usual care. Improvements in pain made a substantial contribution to QoL gains whilst the presence of anxiety and depression and poor baseline performance status significantly constrained improvement.

Hamstring tightness induces posterior pelvic tilt and decreased lumbar lordosis, which can result in low back painOBJECTIVE: We investigated effects of hamstring stretch with pelvic control on pain and work ability in standing workers. One hundred adult volunteers from a standing workers were randomly assigned to pelvic control hamstring stretching (PCHS) (n = 34), general hamstring stretching (GHS) (n = 34), control (n = 32) groups. The control group was performed self-home exercise. All interventions were conducted 3 days per week for 6 weeks, and included in the hamstring stretching and lumbopelvic muscle strengthening. Outcomes were evaluated through the visual analog scale (VAS), straight leg raise test (SLR), sit and reach test (SRT), Oswestry disability index (ODI), and work ability index (WAI). Significant difference in VAS, SLR, SRT, ODI, and WAI were found in the PCHS and GHS groups. The control group was a significant difference only in ODI. The PCHS group showed a greater difference than the GHS group and control group in VAS, SLR, SRT, and ODI. The pelvic control hamstring stretch exercise would be more helpful in back pain reduction and improvement of work ability in an industrial setting.

Objective To evaluate intramuscular ketorolac compared to placebo saline injection for pain control with intrauterine device (IUD) placement. Methods We conducted a randomized, double-blind, placebo controlled trial between July 2012 and March 2014. Patients received ketorolac 30mg or placebo saline intramuscular injection 30 minutes prior to IUD placement. The primary outcome was pain with IUD placement on a 10cm visual analog scale (VAS). Sample size was calculated to provide 80% power to show a 2.0cm difference (α=0.05) in the primary outcome. Secondary outcomes included pain with study drug injection, speculum insertion, tenaculum placement, uterine sounding, and at 5 and 15 minutes after IUD placement. Results A total of 67 women participated in the study, 33 in the ketorolac arm and 34 in the placebo arm. There were no differences in baseline demographics including age, BMI, and race. There were no differences in median pain scores for IUD placement in the placebo versus ketorolac groups (5.2cm vs 3.6cm, p=0.99). There was a decrease in median pain scores at 5 minutes (2.2cm vs 0.3cm, p=<0.001) and 15 minutes (1.6cm vs 0.1cm, p=<0.001) after IUD placement but no difference for all other time points. Nulliparous participants (n=16, 8 per arm) had a decrease in pain scores with IUD placement (8.1cm vs 5.4cm, p=0.02). In this study, 22% of participants in the placebo group and 18% in the ketorolac group reported injection pain was as painful as IUD placement. Conclusions Ketorolac does not reduce pain with IUD placement but does reduce pain at 5 and 15 minutes after placement. PMID:26241253

To determine the efficacy of wet-cupping for treating persistent nonspecific low back pain. Wet-cupping therapy is one of the oldest known medical techniques. It is still used in several contemporary societies. Very minimal empirical study has been conducted on its efficacy. Randomized controlled trial with two parallel groups. Patients in the experimental group were offered the option of referral to the wet-cupping service; all accepted that option. The control group received usual care. Medical clinic in Kermanshah, Iran. In total, 98 patients aged 17-68 years with nonspecific low back pain; 48 were randomly assigned to experimental group and 50 to the control group. Patients in the experimental group were prescribed a series of three staged wet-cupping treatments, placed at 3 days intervals (i.e., 0, 3, and 6 days). Patients in the control group received usual care from their general practitioner. Three outcomes assessed at baseline and again 3 months following intervention: the McGill Present Pain Index, Oswestry Pain Disability Index, and the Medication Quantification Scale. Wet-cupping care was associated with clinically significant improvement at 3-month follow-up. The experimental group who received wet-cupping care had significantly lower levels of pain intensity ([95% confidence interval (CI) 1.72-2.60] mean difference=2.17, p<0.01), pain-related disability (95% CI=11.18-18.82, means difference=14.99, p<0.01), and medication use (95% CI=3.60-9.50, mean difference=6.55, p<0.01) than the control group. The differences in all three measures were maintained after controlling for age, gender, and duration of lower back pain in regression models (p<0.01). Traditional wet-cupping care delivered in a primary care setting was safe and acceptable to patients with nonspecific low back pain. Wet-cupping care was significantly more effective in reducing bodily pain than usual care at 3-month follow-up.

Background Thoracic spine manipulation has become a popular alternative to local cervical manipulative therapy for mechanical neck pain. This study investigated the acute effects of single-level and multiple-level thoracic manipulations on chronic mechanical neck pain (CMNP). Methods Forty-eight patients with CMNP were randomly allocated to single-level thoracic manipulation (STM) at T6–T7 or multiple-level thoracic manipulation (MTM), or to a control group (prone lying). Cervical range of motion (CROM), visual analog scale (VAS), and the Thai version of the Neck Disability Index (NDI-TH) scores were measured at baseline, and at 24-hour and at 1-week follow-up. Results At 24-hour and 1-week follow-up, neck disability and pain levels were significantly (P<0.05) improved in the STM and MTM groups compared with the control group. CROM in flexion and left lateral flexion were increased significantly (P<0.05) in the STM group when compared with the control group at 1-week follow-up. The CROM in right rotation was increased significantly after MTM compared to the control group (P<0.05) at 24-hour follow-up. There were no statistically significant differences in neck disability, pain level at rest, and CROM between the STM and MTM groups. Conclusion These results suggest that both single-level and multiple-level thoracic manipulation improve neck disability, pain levels, and CROM at 24-hour and 1-week follow-up in patients with CMNP.

The aim of this study was to investigate whether isometric neck extension exercise restores physiological cervical lordosis and reduces pain. Sixty-five patients with loss of cervical lordosis were randomly assigned to exercise (27 women, 7 men; mean age, 32.82 ± 8.83 yrs) and control (26 women, 5 men; mean age, 33.48 ± 9.67 yrs) groups. Both groups received nonsteroidal anti-inflammatory drugs for 10 days. The exercise group received additional therapy as a home exercise program, which consisted of isometric neck extension for 3 mos. Neck pain severity and cervical lordosis were measured at baseline and at 3 mos after baseline. Compared with baseline levels, cervical lordosis angle was significantly improved in the exercise group (P < 0.001) but not in the control group (P = 0.371) at the end of 3 mos. Moreover, the exercise group was significantly superior to the control group considering the number of patients in whom cervical lordosis angle returned to physiological conditions (85.2% vs. 22.5%; P < 0.001). At the end of 3 mos, pain intensity was significantly reduced in both groups compared with baseline levels (for all, P < 0.001). Nevertheless, considering the change from baseline to month 3, the reduction in pain was about twice in the exercise group compared with the control group (P < 0.001). Isometric neck extension exercise improves cervical lordosis and pain.

Objective To investigate the effect of surgical decompression on painful diabetic peripheral neuropathy (DPN) patients and discuss the role which pain distribution and characterization play in the management of painful DPN as well as the underlying mechanism involved. Methods A total of 306 patients with painful diabetic lower-extremity neuropathy were treated with Dellon surgical nerve decompression in our department. Clinical evaluation including Visual analogue scale (VAS), Brief Pain Inventory Short Form for diabetic peripheral neuropathy (BPI-DPN) questionnaire, two-point discrimination (2-PD), nerve conduction velocity (NCV) and high-resolution ultrasonography (cross-sectional area, CSA) were performed in all cases preoperatively, and at 6 month intervals for 2 years post-decompression. The patients who underwent surgery were retrospectively assigned into two subgroups (focal and diffuse pain) according to the distribution of the diabetic neuropathic pain. The control group included 92 painful DPN patients without surgery. Results The levels of VAS, scores in BPI-DPN, 2-PD, NCV results and CSA were all improved in surgical group when compared to the control group (P<0.05). More improvement of VAS, scores in BPI-DPN and CSA was observed in focal pain group than that in diffuse group (P<0.05). Conclusions Efficacy of decompression of multiple lower-extremity peripheral nerves in patients with painful diabetic neuropathy was confirmed in this study. While both focal and diffuse group could benefit from surgical decompression, pain relief and morphological restoration could be better achieved in focal group. PMID:25290338

Methods Forty-one subjects who have MPS in the upper trapezius muscles without depression were recruited. The patients were randomly assigned into two groups: the whirlpool therapy group whose bodies were immersed in a whirlpool bath at 34℃-36℃ for 30 minutes; the hydrocollator group who took a 30-minute application of a standard hot hydrocollator pack. Patients in both groups received therapy three days a week for 2 weeks and underwent several evaluations at baseline and after treatment. The variables we analyzed during evaluations were as follows: the primary outcome we considered was pain severity using a visual analogue scale. And the secondary outcomes examined included anxiety using the Korean version of the Beck Anxiety Inventory and quality of life (QoL) using the Korean version of the World Health Organization QoL Assessment, Brief Form. All follow-up values were compared with the baseline values. Results The baseline parameters did not show significant differences between two groups. And after 2-week treatment, both groups revealed significant improvement in anxiety levels and QoL, as well as in pain. However, the improvement on pain (p=0.002) and anxiety (p=0.010) was significantly greater in the whirlpool group, compared to the hydrocollator group. Conclusion The whirlpool hydrotherapy can be used as a more effective therapeutic method to reduce pain and anxiety in chronic MPS patients without depression. PMID:24020034

Musculoskeletal pain (MSP) is the most expensive nonmalignant health problem and the most common reason for activity limitation. Treatment approaches to improve movement without aggravating pain are urgently needed. Virtual reality (VR) can decrease acute pain, as well as influence movement speed. It is not clear whether VR can improve movement speed in individuals with MSP without aggravating pain. This study investigated the extent to which different audio and optic flow cues in a VR environment influenced walking speed in people with and without MSP. A total of 36 subjects participated, 19 with MSP and 17 controls. All walked on a motorized self-paced treadmill interfaced with a three-dimensional virtual walkway. The audio tempo was scaled (75%, 100%, and 125%) from baseline cadence, and optic flow was either absent, or scaled to 50% or 100% of preferred walking speed. Gait speed was measured during each condition, and pain was measured before and after the experiment. Repeated measures analysis of variance showed that audio tempo above baseline cadence significantly increased walking speed in both groups, F(3, 99)=10.41, p<0.001. Walking speed increases of more than 25% occurred in both groups in the 125% audio tempo condition, without any significant increase in pain. There was also a trend toward increased walking speeds with the use of optic flow, but the results in this study did not achieve significance at the p<0.05 level, F(2, 66)=2.01, p=0.14. Further research is needed to establish the generalizability of increasing movement speed across different physical performance tasks in VR.

Background Though moxibustion is frequently used to treat primary dysmenorrhea in China, relevant evidence supporting its effectiveness is still scanty. Methods This study was a pragmatic randomized, conventional drug controlled, open-labeled clinical trial. After initial screen, 152 eligible participants were averagely randomized to receive two different treatment strategies: Moxibustion and conventional drugs. Participants and practitioners were not blinded in this study. The duration of each treatment was 3 months. The primary outcome was pain relief measured by the Visual Analogue Scale. The menstrual pain severity was recorded in a menstrual pain diary. Results 152 eligible patients were included but only 133 of them eventually completed the whole treatment course. The results showed that the menstrual pain intensity in experimental group and control group was reduced from 6.38±1.28 and 6.41±1.29, respectively, at baseline, to 2.54±1.41 and 2.47±1.29 after treatment. The pain reduction was not significantly different between these two groups (P = 0.76), however; the pain intensity was significantly reduced relative to baseline for each group (P<0.01). Three months after treatment, the effectiveness of moxibustion sustained and started to be superior to the drug’s effect (-0.87, 95%CI -1.32 to -0.42, P<0.01). Secondary outcome analyses showed that moxibustion was as effective as drugs in alleviating menstrual pain-related symptoms. The serum levels of pain mediators, such as PGF2α, OT, vWF, β-EP, PGE2, were significantly improved after treatment in both groups (P<0.05). No adverse events were reported in this trial. Conclusions Both moxibustion and conventional drug showed desirable merits in managing menstrual pain, given their treatment effects and economic costs. This study as a pragmatic trial only demonstrates the effectiveness, not the efficacy, of moxibustion for menstrual pain. It can’t rule out the effect of psychological factors during

To investigate the effects of mirror therapy on upper limb motor functions, spasticity, and pain intensity in patients with hemiplegia accompanied by complex regional pain syndrome type 1. Randomized controlled trial. Training and research hospital. Adult patients with first-time stroke and simultaneous complex regional pain syndrome type 1 of the upper extremity at the dystrophic stage (N=30). Both groups received a patient-specific conventional stroke rehabilitation program for 4 weeks, 5 d/wk, for 2 to 4 h/d. The mirror therapy group received an additional mirror therapy program for 30 min/d. We evaluated the scores of the Brunnstrom recovery stages of the arm and hand for motor recovery, wrist and hand subsections of the Fugl-Meyer Assessment (FMA) and motor items of the FIM-motor for functional status, Modified Ashworth Scale (MAS) for spasticity, and visual analog scale (VAS) for pain severity. After 4 weeks of rehabilitation, both groups had significant improvements in the FIM-motor and VAS scores compared with baseline scores. However, the scores improved more in the mirror therapy group than the control group (P<.001 and P=.03, respectively). Besides, the patients in the mirror therapy arm showed significant improvement in the Brunnstrom recovery stages and FMA scores (P<.05). No significant difference was found for MAS scores. In patients with stroke and simultaneous complex regional pain syndrome type 1, addition of mirror therapy to a conventional stroke rehabilitation program provides more improvement in motor functions of the upper limb and pain perception than conventional therapy without mirror therapy.

Pain intensity attenuates muscular activity, proprioception, and tactile acuity, with consequent changes of joint kinematics. People suffering from low back pain (LBP) frequently show movement control impairments of the lumbar spine in sagittal plane. This cross-sectional, observational study investigated if the intensity of LBP attenuates lumbar movement control. The hypothesis was that lumbar movement control becomes more limited with increased pain intensity. The effect of LBP intensity, measured with a numeric rating scale (NRS), on lumbar movement control was tested using three movement control tests. The lumbar range of motion (ROM), the ratio of lumbar and hip ROM as indicators of direction specific movement control, and the recurrence and determinism of repetitive lumbar movement patterns were assessed in ninety-four persons suffering from LBP of different intensity and measured with an inertial measurement unit system. Generalized linear models were fitted for each outcome. Lumbar ROM (+ 0.03°, p = 0.24) and ratio of lumbar and hip ROM (0.01, p = 0.84) were unaffected by LBP intensity. Each one point increase on the NRS resulted in a decrease of recurrence and determinism of lumbar movement patterns (-3.11 to -0.06, p ⩽ 0.05). Our results indicate changes in movement control in people suffering from LBP. Whether decreased recurrence and determinism of lumbar movement patterns are intensifiers of LBP intensity or a consequence thereof should be addressed in a future prospective study.

Cupping, a classic Chinese medicine treatment, is a technique that applies suction cups over soft tissue. Cupping is gaining popularity in physical medicine because of the simplicity in application, minimal adverse effects, and reduction in pain and muscle tenderness. These factors also make it a cost-effective intervention. For this study, cupping was used to treat low back pain (LBP). To evaluate the effectiveness of Chinese cupping in acutely reducing pain, decreasing tenderness to palpation, and improving range of motion for patients with subacute or chronic LBP. Twenty-one patients who reported back pain for at least 8 weeks volunteered at a multidisciplinary holistic outpatient clinic. After completion of a medical screening questionnaire and collection of baseline data, 4 glass cups were applied and pressurized over the lower erector spinae muscles. Baseline data included demographic characteristics and the Oswestry Disability Questionnaire score. Pre- and postintervention data included perceived pain on a visual analog scale (VAS), lumbar spine range of motion, straight-leg raise test (SLR), and pain-pressure threshold (PPT) assessed with a digital force gauge. The data were analyzed by using a Wilcoxon signed-rank test and Spearman rho correlations. Of the 17 patients who completed the study, there were significant post-treatment improvements in VAS scores (p=0.0001), SLR motion on the left (p=0.043), and lumbar flexion range of motion (p=0.016) and improvements in PPT at all 4 investigated points (p<0.007). Significant relationships were identified between the improvement in low back flexion with the improvement in PPT at bilateral lumbar paraspinal muscles at the L4 levels and at the left L2 level. Chinese cupping may be a low-risk, therapeutic treatment for the prompt reduction of symptoms associated with subacute and chronic low back pain. Cupping may allow patients to progress to functional movement training in a timely manner by promptly reducing

Previous studies have reported that stretching of the calf musculature and the plantar fascia are effective management strategies for plantar heel pain (PHP). However, it is unclear whether myofascial release (MFR) can improve the outcomes in this population. To investigate whether myofascial release (MFR) reduces the pain and functional disability associated with plantar heel pain (PHP) in comparison with a control group receiving sham ultrasound therapy (SUST). Randomized, controlled, double blinded trial. Nonprofit research foundation clinic in India. Sixty-six patients, 17 men and 49 women with a clinical diagnosis of PHP were randomly assigned into MFR or a control group and given 12 sessions of treatment per client over 4 weeks. The Foot Function Index (FFI) scale was used to assess pain severity and functional disability. The primary outcome measure was the difference in FFI scale scores between week 1 (pretest score), week 4 (posttest score), and follow-up at week 12 after randomization. Additionally, pressure pain thresholds (PPT) were assessed over the affected gastrocnemii and soleus muscles, and over the calcaneus, by an assessor blinded to the treatment allocation. The simple main effects analysis showed that the MFR group performed better than the control group in weeks 4 and 12 (P<0.001). Patients in the MFR and control groups reported a 72.4% and 7.4% reduction, respectively, in their pain and functional disability in week 4 compared with that in week 1, which persisted as 60.6% in the follow-up at week 12 in the MFR group compared to the baseline. The mixed ANOVA also revealed significant group-by-time interactions for changes in PPT over the gastrocnemii and soleus muscles, and the calcaneus (P<0.05). This study provides evidence that MFR is more effective than a control intervention for PHP. Copyright © 2014 Elsevier Ltd. All rights reserved.

Improved early pain control may affect the longer-term prevalence of persistent pain. In a previous randomised, controlled trial, we found that the administration of ketamine on hospital arrival decreased pain scores to a greater extent than morphine alone in patients with prehospital traumatic pain. In this follow-up study, we sought to determine the prevalence of persistent pain and whether there were differences in patients who received ketamine or morphine. This study was a long-term follow-up study of the prehospital, prospective, randomised, controlled, open-label study comparing ketamine with morphine in patients with trauma and a verbal pain score of >5 after 5 mg intravenous morphine. Patients were followed-up by telephone 6-12 months after enrollment, and a questionnaire including the SF-36 (V.2) health-related quality of life survey and the Verbal Numerical Rating Scale for pain was administered. A total of 97/135 (72%) patients were able to be followed-up 6-12 months after enrollment between July 2008 and July 2010. Overall, 44/97 (45%) participants reported persistent pain related to their injury, with 3/97 (3%) reporting persistent severe pain. The prevalence of persistent pain was the same between study groups (22/50 (44%) for the ketamine group vs 22/47 (46%) for the morphine group). There was no difference in the SF-36 scores between study arms. There is a high incidence of persistent pain after traumatic injury, even in patients with relatively minor severity of injury. Although decreased pain scores at hospital arrival are achieved with ketamine compared with morphine, this difference does not affect the prevalence of persistent pain or health-related quality of life 6 months after injury.

Potential of Endocannabinoids to Control Bladder Pain.

PubMed

Bjorling, Dale E; Wang, Zun-Yi

2018-01-01

Bladder-related pain is one of the most common forms of visceral pain, and visceral pain is among the most common complaints for which patients seek physician consultation. Despite extensive studies of visceral innervation and treatment of visceral pain, opioids remain a mainstay for management of bladder pain. Side effects associated with opioid therapy can profoundly diminish quality of life, and improved options for treatment of bladder pain remain a high priority. Endocannabinoids, primarily anandamide (AEA) and 2-arachidonoylglycerol (2-AG), are endogenously-produced fatty acid ethanolamides with that induce analgesia. Animal experiments have demonstrated that inhibition of enzymes that degrade AEA or 2-AG have the potential to prevent development of visceral and somatic pain. Although experimental results in animal models have been promising, clinical application of this approach has proven difficult. In addition to fatty acid amide hydrolase (FAAH; degrades AEA) and monacylglycerol lipase (MAGL; degrades 2-AG), cyclooxygenase (COX) acts to metabolize endocannabinoids. Another potential limitation of this strategy is that AEA activates pro-nociceptive transient receptor potential vanilloid 1 (TRPV1) channels. Dual inhibitors of FAAH and TRPV1 or FAAH and COX have been synthesized and are currently undergoing preclinical testing for efficacy in providing analgesia. Local inhibition of FAAH or MAGL within the bladder may be viable options to reduce pain associated with cystitis with fewer systemic side effects, but this has not been explored. Further investigation is required before manipulation of the endocannabinoid system can be proven as an efficacious alternative for management of bladder pain.

The influence of a series of five dry cupping treatments on pain and mechanical thresholds in patients with chronic non-specific neck pain - a randomised controlled pilot study

Background In this preliminary trial we investigated the effects of dry cupping, an ancient method for treating pain syndromes, on patients with chronic non-specific neck pain. Sensory mechanical thresholds and the participants' self-reported outcome measures of pain and quality of life were evaluated. Methods Fifty patients (50.5 ± 11.9 years) were randomised to a treatment group (TG) or a waiting-list control group (WL). Patients in the TG received a series of 5 cupping treatments over a period of 2 weeks; the control group did not. Self-reported outcome measures before and after the cupping series included the following: Pain at rest (PR) and maximal pain related to movement (PM) on a 100-mm visual analogue scale (VAS), pain diary (PD) data on a 0-10 numeric rating scale (NRS), Neck Disability Index (NDI), and health-related quality of life (SF-36). In addition, the mechanical-detection thresholds (MDT), vibration-detection thresholds (VDT), and pressure-pain thresholds (PPT) were determined at pain-related and control areas. Results Patients of the TG had significantly less pain after cupping therapy than patients of the WL group (PR: Δ-22.5 mm, p = 0.00002; PM: Δ-17.8 mm, p = 0.01). Pain diaries (PD) revealed that neck pain decreased gradually in the TG patients and that pain reported by the two groups differed significantly after the fifth cupping session (Δ-1.1, p = 0.001). There were also significant differences in the SF-36 subscales for bodily pain (Δ13.8, p = 0.006) and vitality (Δ10.2, p = 0.006). Group differences in PPT were significant at pain-related and control areas (all p < 0.05), but were not significant for MDT or VDT. Conclusions A series of five dry cupping treatments appeared to be effective in relieving chronic non-specific neck pain. Not only subjective measures improved, but also mechanical pain sensitivity differed significantly between the two groups, suggesting that cupping has an influence on functional pain processing.

Evidence-based pharmacological and behavioral interventions are often underutilized or inaccessible to persons with multiple sclerosis (MS) who have chronic pain and/or depression. Collaborative care is an evidence-based patient-centered, integrated, system-level approach to improving the quality and outcomes of depression care. We describe the development of and randomized controlled trial testing a novel intervention, MS Care, which uses a collaborative care model to improve the care of depression and chronic pain in a MS specialty care setting. We describe a 16-week randomized controlled trial comparing the MS Care collaborative care intervention to usual care in an outpatient MS specialty center. Eligible participants with chronic pain of at least moderate intensity (≥3/10) and/or major depressive disorder are randomly assigned to MS Care or usual care. MS Care utilizes a care manager to implement and coordinate guideline-based medical and behavioral treatments with the patient, clinic providers, and pain/depression treatment experts. We will compare outcomes at post-treatment and 6-month follow up. We hypothesize that participants randomly assigned to MS Care will demonstrate significantly greater control of both pain and depression at post-treatment (primary endpoint) relative to those assigned to usual care. Secondary analyses will examine quality of care, patient satisfaction, adherence to MS care, and quality of life. Study findings will aid patients, clinicians, healthcare system leaders, and policy makers in making decisions about effective care for pain and depression in MS healthcare systems.

We conducted a double-blind, placebo-controlled, crossover study evaluating the analgesic efficacy of vaporized cannabis in subjects, the majority of whom were experiencing neuropathic pain despite traditional treatment. Thirty-nine patients with central and peripheral neuropathic pain underwent a standardized procedure for inhaling medium-dose (3.53%), low-dose (1.29%), or placebo cannabis with the primary outcome being visual analog scale pain intensity. Psychoactive side effects and neuropsychological performance were also evaluated. Mixed-effects regression models demonstrated an analgesic response to vaporized cannabis. There was no significant difference between the 2 active dose groups' results (P > .7). The number needed to treat (NNT) to achieve 30% pain reduction was 3.2 for placebo versus low-dose, 2.9 for placebo versus medium-dose, and 25 for medium- versus low-dose. As these NNTs are comparable to those of traditional neuropathic pain medications, cannabis has analgesic efficacy with the low dose being as effective a pain reliever as the medium dose. Psychoactive effects were minimal and well tolerated, and neuropsychological effects were of limited duration and readily reversible within 1 to 2 hours. Vaporized cannabis, even at low doses, may present an effective option for patients with treatment-resistant neuropathic pain. The analgesia obtained from a low dose of delta-9-tetrahydrocannabinol (1.29%) in patients, most of whom were experiencing neuropathic pain despite conventional treatments, is a clinically significant outcome. In general, the effect sizes on cognitive testing were consistent with this minimal dose. As a result, one might not anticipate a significant impact on daily functioning. Published by Elsevier Inc.

Pain-related guilt in low back pain.

2014-12-01

Identifying mechanisms that mediate recovery is imperative to improve outcomes in low back pain (LBP). Qualitative studies suggest that guilt may be such a mechanism, but research on this concept is scarce, and reliable instruments to measure pain-related guilt are not available. We addressed this gap by developing and testing a Pain-related Guilt Scale (PGS) for people with LBP. Two samples of participants with LBP completed the scale and provided data on rates of depression, anxiety, pain intensity, and disability. Three factors were identified using exploratory factor analysis (n=137): "Social guilt," (4 items) relating to letting down family and friends; "Managing condition/pain guilt," (5 items) relating to failing to overcome and control pain; and "Verification of pain guilt," (3 items) relating to the absence of objective evidence and diagnosis. This factor structure was confirmed using confirmatory factor analysis (n=288), demonstrating an adequate to good fit with the data (AGFI=0.913, RMSEA=0.061). The PGS subscales positively correlated with depression, anxiety, pain intensity, and disability. After controlling for depression and anxiety the majority of relationships between the PGS subscales and disability and pain intensity remained significant, suggesting that guilt shared unique variance with disability and pain intensity independent of depression and anxiety. High levels of guilt were reported by over 40% of participants. The findings suggest that pain-related guilt is common and is associated with clinical outcomes. Prospective research is needed to examine the role of guilt as a predictor, moderator, and mediator of patients' outcomes.

To establish the effectiveness of walking alone and walking compared to other non-pharmacological management methods to improve disability, quality of life, or function in adults with chronic low back pain. A systematic search of the following databases was undertaken: Medline, Embase, CINAHL, Scopus, Pedro, SportDiscus, Cochrane Central Register of Controlled Trials. The following keywords were used: 'back pain' or 'low back pain' or 'chronic low back pain' and 'walk*' or 'ambulation' or 'treadmill*' or 'pedometer*' or 'acceleromet*' or 'recreational' and 'disability' or 'quality of life' or 'function*'. Primary research studies with an intervention focus that investigated walking as the primary intervention compared to no intervention or any other non-pharmacological method in adults with chronic low back pain (duration >3 months). Seven randomised controlled trials involving 869 participants were included in the review. There was no evidence that walking was more effective than other management methods such as usual care, specific strength exercises, medical exercise therapy, or supervised exercise classes. One study found over-ground walking to be superior to treadmill walking, and another found internet-mediated walking to be more beneficial than non-internet-mediated walking in the short term. There is low quality evidence to suggest that walking is as effective as other non-pharmacological management methods at improving disability, function, and quality of life in adults with chronic low back pain. © The Author(s) 2015.

Chronic pain is a common and serious health problem in older patients. Treatment often includes non pharmacological approaches despite a relatively modest evidence base in this population. Hypnosis has been used in younger adults with positive results. The main objective of this study was to measure the feasibility and efficacy of hypnosis (including self hypnosis) in the management of chronic pain in older hospitalized patients. A single center randomized controlled trial using a two arm parallel group design (hypnosis versus massage). Inclusion criteria were chronic pain for more than 3 months with impact on daily life activities, intensity of > 4; adapted analgesic treatment; no cognitive impairment. Brief pain inventory was completed. Fifty-three patients were included (mean age: 80.6 ± 8.2--14 men; 26 hypnosis; 27 massage. Pain intensity decreased significantly in both groups after each session. Average pain measured by the brief pain index sustained a greater decrease in the hypnosis group compared to the massage group during the hospitalisation. This was confirmed by the measure of intensity of the pain before each session that decreased only in the hypnosis group over time (P = 0.008). Depression scores improved significantly over the time only in the hypnosis group (P = 0.049). There was no effect in either group 3 months post hospitals discharge. Hypnosis represents a safe and valuable tool in chronic pain management of hospitalized older patients. In hospital interventions did not provide long term post discharge relief.

Objectives. To evaluate the association between improvements in physical function, fatigue and pain and improvements in productivity at work and at home in patients treated with certolizumab pegol (CZP) in combination with MTX. Methods. Physical function, fatigue and pain were assessed in two CZP clinical trials (Rheumatoid Arthritis PreventIon of structural Damage 1 and 2) using the HAQ-Disability Index (HAQ-DI), Fatigue Assessment Scale (FAS) and Patient Assessment of Pain, with minimal clinically important differences (MCIDs) defined as ≥0.22, ≥1 and ≥10 points, respectively. Work and home productivity were evaluated using the RA-specific Work Productivity Survey (WPS-RA). The odds of achieving an HAQ-DI, FAS or pain ‘response’ at Week 12, defined as improvements ≥MCID, were compared between CZP and control groups. Improvements in productivity at Week 12 were compared between CZP-treated HAQ-DI, FAS or pain responders and non-responders. Results. The odds of achieving improvements ≥MCID were five times higher for pain, and two to three times higher for physical function and fatigue, in patients receiving CZP vs control. Per month, responders reported significantly greater improvements in productivity at work and reduced interference of RA with their work productivity than non-responders. Responders also reported significantly greater improvements in productivity at home and participation in family, social and leisure activities. Conclusions. This study demonstrated a clear association between patient-reported improvements in physical function, fatigue and pain, and improvements in productivity both at work and home. PMID:20547658

Altered motor control patterns in whiplash and chronic neck pain.

Woodhouse, Astrid; Vasseljen, Ottar

2008-06-20

Persistent whiplash associated disorders (WAD) have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM), conjunct motion, joint position error and ROM-variability. Participants (n = 173) were recruited to three groups: 59 patients with persistent WAD, 57 patients with chronic non-traumatic neck pain and 57 asymptomatic volunteers. A 3D motion tracking system (Fastrak) was used to record maximal range of motion in the three cardinal planes of the cervical spine (sagittal, frontal and horizontal), and concurrent motion in the two associated cardinal planes relative to each primary plane were used to express conjunct motion. Joint position error was registered as the difference in head positions before and after cervical rotations. Reduced conjunct motion was found for WAD and chronic neck pain patients compared to asymptomatic subjects. This was most evident during cervical rotation. Reduced conjunct motion was not explained by current pain or by range of motion in the primary plane. Total conjunct motion during primary rotation was 13.9 degrees (95% CI; 12.2-15.6) for the WAD group, 17.9 degrees (95% CI; 16.1-19.6) for the chronic neck pain group and 25.9 degrees (95% CI; 23.7-28.1) for the asymptomatic group. As expected, maximal cervical range of motion was significantly reduced among the WAD patients compared to both control groups. No group differences were found in maximal ROM-variability or joint position error. Altered movement patterns in the cervical spine were found for both pain groups, indicating changes in motor control strategies. The changes were not related to a history of neck trauma, nor to current pain, but more

2015-04-01

This randomized controlled clinical trial investigated the effects of mindfulness meditation on chronic pain. A total of 109 patients with nonspecific chronic pain were randomized to either a standardized mindfulness meditation program (mindfulness-based stress reduction [MBSR]) or to a wait list control. Pain, physical function, mental function, pain acceptance, and health-related quality of life were measured. The SF36 vitality scale was chosen as the primary outcome measure; the primary end point was after completing the MBSR course. Within a 2.5-year period, 43 of the 109 randomized patients completed the mindfulness program, while 47 remained in the control group. Data were compared at three time points: at baseline, after completion of the course/waiting period, and at the 6-month follow-up. Significant effect (Cohen's d = 0.39) was found on the primary outcome measure, the SF36 vitality scale. On the secondary variables, significant medium to large size effects (Cohen's d = 0.37-0.71) were found for lower general anxiety and depression, better mental quality of life (psychological well-being), feeling in control of the pain, and higher pain acceptance. Small (nonsignificant) effect sizes were found for pain measures. There were no significant differences in the measures just after the intervention vs the 6-month follow-up. A standardized mindfulness program (MBSR) contributes positively to pain management and can exert clinically relevant effects on several important dimensions in patients with long-lasting chronic pain. © 2014 American Academy of Pain Medicine.

Muscle pain is a natural consequence of intense and prolonged exercise and has been suggested to be a limiter of performance. Transcutaneous electrical nerve stimulation (TENS) and interferential current (IFC) have been shown to reduce both chronic and acute pain in a variety of conditions. This study sought to ascertain whether TENS and IFC could reduce exercise-induced pain (EIP) and whether this would affect exercise performance. It was hypothesised that TENS and IFC would reduce EIP and result in an improved exercise performance. In two parts, 18 (Part I) and 22 (Part II) healthy male and female participants completed an isometric contraction of the dominant bicep until exhaustion (Part I) and a 16.1 km cycling time trial as quickly as they could (Part II) whilst receiving TENS, IFC, and a SHAM placebo in a repeated measures, randomised cross-over, and placebo-controlled design. Perceived EIP was recorded in both tasks using a validated subjective scale. In Part I, TENS significantly reduced perceived EIP (mean reduction of 12%) during the isometric contraction (P = 0.006) and significantly improved participants' time to exhaustion by a mean of 38% (P = 0.02). In Part II, TENS significantly improved (P = 0.003) participants' time trial completion time (~2% improvement) through an increased mean power output. These findings demonstrate that TENS can attenuate perceived EIP in a healthy population and that doing so significantly improves endurance performance in both submaximal isometric single limb exercise and whole-body dynamic exercise.

To compare the efficacy of posterolateral hip muscle strengthening versus quadriceps strengthening in reducing pain and improving health status in persons with patellofemoral pain (PFP). Comparative control trial. Rehabilitation facility. Persons with a diagnosis of PFP (N=36; 18 men, 18 women). Patients were alternately assigned to a posterolateral hip muscle strengthening group (9 men and 9 women) or a quadriceps strengthening group (9 men and 9 women). The posterolateral hip muscle strengthening group performed hip abductor and external rotator strengthening exercises, whereas the quadriceps strengthening group performed quadriceps strengthening exercises (3 times a week for 8wk). Pain (visual analog scale [VAS]) and health status (Western Ontario McMaster Universities Osteoarthritis Index [WOMAC]) were assessed at baseline, postintervention, and 6-month follow-up. Significant improvements in VAS and WOMAC scores were observed in both groups from baseline to postintervention and baseline to 6-month follow-up (P<.001). Improvements in VAS and WOMAC scores in the posterolateral hip exercise group were superior to those in the quadriceps exercise group postintervention and at 6-month follow-up (P<.05). Although both intervention programs resulted in decreased pain and improved function in persons with PFP, outcomes in the posterolateral hip exercise group were superior to the quadriceps exercise group. The superior outcomes obtained in the posterolateral hip exercise group were maintained 6 months postintervention. Copyright © 2014 American Congress of Rehabilitation Medicine.

Empirical reports suggest that oral habits (e.g., teeth clenching) may be behavioral mediators linking stress to muscle hyperreactivity and the development of facial pain. Another report suggests that excessive behavioral adjuncts develop in conjunction with fixed-time stimulus presentation. The present study assessed the extent to which the oral habits exhibited by facial pain patients are schedule-induced. Subjects with Temporomandibular Disorder (TMD) symptomatology (n = 15) and pain-free controls (n = 15) participated in a 4-phase experiment (adaptation, baseline, task, recovery) designed to elicit schedule-induced behaviors. Self-report of oral habits and negative affect were recorded after each phase. Objective measures of oral habits were obtained via behavioral observation and masseter EMG recordings. Results revealed that negative arousal significantly increased during the fixed-time (FT) task and was also associated with increased oral habits among the TMD subjects. Moreover, 40% of the TMD subjects and none of the controls exhibited a pattern of EMG elevations in the early part of the inter-stimulus interval that met a strict criteria for scheduled-induced behavior per se. Taken together, these results suggest that the TMD subjects were engaging in schedule-induced oral habits. The adjunctive behavior literature seems to provide a plausible explanation as to how oral habits develop and are maintained in TMD patients, despite their painful consequences.

Purpose. Aromatherapy massage is an alternative treatment in reducing the pain of the cancer patients. This study was to investigate whether aromatherapy massage could improve the pain of the cancer patients. Methods. We searched PubMed and Cochrane Library for relevant randomized controlled trials without language limitations between 1 January 1990 and 31 July 2015 with a priori defined inclusion and exclusion criteria. The search terms included aromatherapy, essential oil, pain, ache, cancer, tumor, and carcinoma. There were 7 studies which met the selection criteria and 3 studies were eventually included among 63 eligible publications. Results. This meta-analysis included three randomized controlled trials with a total of 278 participants (135 participants in the massage with essential oil group and 143 participants in the control (usual care) group). Compared with the control group, the massage with essential oil group had nonsignificant effect on reducing the pain (standardized mean difference = 0.01; 95% CI [-0.23,0.24]). Conclusion. Aromatherapy massage does not appear to reduce pain of the cancer patients. Further rigorous studies should be conducted with more objective measures.

Patellar taping has been a part of intervention for treatment of patellofemoral pain syndrome (PFPS). However, research on the efficacy of patellar taping on lower extremity kinematics and dynamic postural control is limited. To evaluate the effects of patellar taping on sagittal-plane hip and knee kinematics, reach distance, and perceived pain level during the Star Excursion Balance Test (SEBT) in individuals with and without PFPS. Repeated-measures design with 2 within-subjects factors and 1 between-subjects factor. The University of Toledo Athletic Training Research Laboratory. Twenty participants with PFPS and 20 healthy participants between the ages of 18 and 29 years. The participants performed 3 reaches of the SEBT in the anterior direction under tape and no-tape conditions on both legs. The participants' hip and knee sagittal-plane kinematics were measured using the electromagnetic tracking system. Reach distance was recorded by hand and was normalized by dividing the distance by the participants' leg length (%MAXD). After each taping condition on each leg, the participants rated the perceived pain level using the 10-cm visual analog scale. The participants with PFPS had a reduction in pain level with patellar tape application compared with the no-tape condition (P = .005). Additionally, participants with PFPS demonstrated increased %MAXD under the tape condition compared with the no-tape condition, whereas the healthy participants demonstrated decreased %MAXD with tape versus no tape (P = .028). No statistically significant differences were noted in hip flexion and knee flexion angles. Although patellar taping seemed to reduce pain and improve SEBT performance of participants with PFPS, the exact mechanisms of these phenomena cannot be explained in this study. Further research is warranted to investigate the effect of patellar taping on neuromuscular control during dynamic postural control.

The aim of this study was to identify baseline predictors of achieving patient-perceived satisfactory improvement (PPSI) in pain after 6 months of treat to target in patients with early RA. Baseline and 6 month data were used from patients included in the Dutch Rheumatoid Arthritis Monitoring remission induction cohort study. Simple and multivariable logistic regression analyses were used to identify significant predictors of achieving an absolute improvement of 30 mm or a relative improvement of 50% on a visual analogue scale for pain. At 6 months, 125 of 209 patients (59.8%) achieved an absolute PPSI and 130 patients (62.2%) achieved a relative PPSI in pain. Controlling for baseline pain, having symmetrical arthritis was the strongest independent predictor of achieving an absolute [odds ratio (OR) 3.17, P = 0.03] or relative (OR 3.44, P = 0.01) PPSI. Additionally, anti-CCP positivity (OR 2.04, P = 0.04) and having ≤12 tender joints (OR 0.29, P = 0.01) were predictive of achieving a relative PPSI. The total explained variance of baseline predictors was 30% for absolute and 18% for relative improvements, respectively. Symmetrical joint involvement, anti-CCP positivity and fewer tender joints at baseline are prognostic signs for achieving satisfactory improvement in pain after 6 months of treat to target in patients with early RA. © The Author 2014.

Bunion: Strengthening Foot Muscles to Reduce Pain and Improve Mobility.

PubMed

2016-07-01

Foot pain discourages physical activity, and less activity harms overall health. Bunion, extra bone and tissue at the base of the big toe, is a frequent cause of foot pain. More than 64 million Americans have bunions that can lead to painful walking. Bunions affect some 35% of women over the age of 65. Bunions can be removed by surgery, which can reduce pain and improve your ability to walk and exercise, but up to 15% of bunions return. Weak muscles may play a role in bunion-related pain and movement problems. In a review of prior research and commentary on this topic published in the July 2016 issue of JOSPT, the author identifies muscle-strengthening exercises that may help people with bunions.

To investigate the short-term effect of transcutaneous electrical nerve stimulation (TENS) by examining pain intensity, pressure pain threshold (PPT) and electromyography (EMG) activity in patients with temporomandibular disorder (TMD). Forty patients with myofascial TMD were enrolled in this randomized placebo-controlled trial and were divided into two groups: active (n=20) and placebo (n=20) TENS. Outcome variables assessed at baseline (T0), immediately after (T2) and 48 hours after treatment (T1) were: pain intensity with the aid of a visual analogue scale (VAS); PPT of masticatory and cervical structures; EMG activity during mandibular rest position (MR), maximal voluntary contraction (MVC) and habitual chewing (HC). Two-way ANOVA for repeated measures was applied to the data and the significance level was set at 5%. There was a decrease in the VAS values at T1 and T2 when compared with T0 values in the active TENS group (p<0.050). The PPT between-group differences were significant at T1 assessment of the anterior temporalis and sternocleidomastoid (SCM) and T2 for the masseter and the SCM (p<0.050). A significant EMG activity reduction of the masseter and anterior temporalis was presented in the active TENS during MR at T1 assessment when compared with T0 (p<0.050). The EMG activity of the anterior temporalis was significantly higher in the active TENS during MVC at T1 and T2 when compared with placebo (p<0.050). The EMG activity of the masseter and anterior temporalis muscle was significantly higher in the active TENS during HC at T1 when compared with placebo (p<0.050). The short-term therapeutic effects of TENS are superior to those of the placebo, because of reported facial pain, deep pain sensitivity and masticatory muscle EMG activity improvement.

We present a technical protocol for rigorous assessment of patient-reported outcomes and psychophysical testing relevant to lumbar sympathetic blocks for the treatment of postamputation pain (PAP). This description is intended to inform future prospective investigation. Series of four participants from a blinded randomized sham-controlled trial. Tertiary, urban, academic pain medicine center. Four participants with a single lower limb amputation and associated chronic PAP. Participants were randomized to receive a lumbar sympathetic block with 0.25% bupivacaine or sham needle placement. Patient-rated outcome measures included the numerical rating scale (NRS) for pain, the McGill Pain Questionnaire-Short Form, Center for Epidemiological Studies Depression Scale, Pain and Anxiety Symptoms Scale-short version, and Pain Disability Index (PDI). Psychophysical and biometric testing was also performed, which included vibration sensation testing, pinprick sensation testing, brush sensation testing, Von Frey repeated weighted pinprick sensation, and thermal quantitative sensory testing. In the four described cases, treatment of PAP with a single lumbar sympathetic block but not sham intervention resulted in reduction of both residual limb pain and phantom limb pain as well as perceived disability on the PDI at three-month follow-up. An appropriately powered randomized controlled study using this methodology may not only aid in determining the possible clinical efficacy of lumbar sympathetic block in PAP, but could also improve our understanding of underlying pathophysiologic mechanisms of PAP.

Randomized clinical trial. To investigate the influence of strengthening the hip abductor and lateral rotator musculature on pain and function of females with patellofemoral pain syndrome (PFPS). Hip muscle weakness in women athletes has been the focus of many recent studies and is suggested as an important impairment to address in the conservative treatment of women with PFPS. However, it is still not well established if strengthening these muscles is associated with clinical improvement in pain and function in sedentary females with PFPS. Seventy females (average±SD age, 25±07 years), with a diagnosis of unilateral PFPS, were distributed randomly into 3 groups: 22 females in the knee exercise group, who received a conventional treatment that emphasized stretching and strengthening of the knee musculature; 23 females in the knee and hip exercise group, who performed exercises to strengthen the hip abductors and external rotators in addition to the same exercises performed by those in the knee exercise group; and of the 25 females who did not receive any treatment. The females of the nontreatment group (control) were instructed to maintain their normal daily activities. An 11-point numerical pain rating scale (NPRS) was used to assess pain during stair ascent and descent. The lower extremity functional scale (LEFS) and the anterior knee pain scale (AKPS) were used to assess function. The single-limb single hop test was also used as a functional outcome to measure preintervention and 4-week postintervention function. The 3 groups were homogeneous prior to treatment in respect to demographic, pain, and functional scales data. Both the knee exercise and the knee and hip exercise groups showed significant improvement in the LEFS, the AKPS, and the NPRS, when compared to the control group (P<.05 and P<.001, respectively). But, when we considered minimal clinically important differences, only the knee and hip exercise group demonstrated mean improvements in AKPS and

A literature review exploring how healthcare professionals contribute to the assessment and control of postoperative pain in older people.

Little research has examined the care older people receive in the acute surgical setting. Although pain assessment and management are judged to be a priority in nursing, often pain, in older people, is undermanaged for a variety of reasons. Factors such as stoicism, communication and ageism can shape both the patients' and nurses' attitude towards the perception of pain which subsequently affects pain management. Through a review of the literature, this paper aims to: (i) identify how healthcare professionals contribute to the assessment and control of postoperative pain in older people and (ii) explore potential barriers to achieving more advantageous pain control in this group. It is suggested that to improve pain management there is a need to individualize pain assessment for older people and to assist clinicians with enhancing their education and decision-making abilities in this field. This may best be achieved by supporting a programme of change to develop the skills of staff and encouraging learning through reflective practice. There is however a need for further research in this area.

Women in chronic pain: sense of control and encounters with health professionals.

PubMed

Skuladottir, Hafdis; Halldorsdottir, Sigridur

2008-07-01

An evolving theory on "women's sense of control while in chronic pain and the results of the quality of their encounters with health professionals" is introduced in this article. According to the theory, the main challenge of women in chronic pain is to maintain a sense of control of self and the pain to avoid demoralization, which is seen as a potential threat for all women in chronic pain. To retain a sense of control, women are challenged to learn to live with the pain and cope with the unpredictability and incurability of the pain. They are challenged to find meaning in their suffering, to create personal space, and to be self-protective as well as to keep a positive self-image and self-esteem while trying to live a "normal" life in dignity in spite of the pain and warding off isolation and demoralization. Health professionals are seen as potentially powerful people in the lives of women in chronic pain. Empowerment or disempowerment from them greatly influences whether women in chronic pain are demoralized or not.

To demonstrate feasibility and estimate the effect of an intervention to increase parental involvement in infant pain management in the NICU on parents' stress and postdischarge parenting competence and confidence. The study involved a randomized controlled trial. Parents recruited from 4 NICUs were randomly assigned by site to receive (1) a pain information booklet and instruction on infant comforting techniques (n = 84 intervention) in addition to a generic NICU care booklet or (2) the generic NICU care booklet alone (n = 85 control). The primary outcome was postintervention Parent Stressor Scale: NICU (PSS:NICU) scores. Secondary outcomes included parent attitudes about infant pain, nursing pain assessment, and parenting competence and role attainment after discharge. No differences were found between groups in PSS:NICU scores. Significant differences favoring the intervention group were found for satisfaction with pain information, parents shown infant pain cues and comforting techniques, nursing pain assessment, and parent preference for involvement during painful procedures. Role attainment after discharge was higher for the intervention group than for the control group. Both the intervention and control groups highly valued attention to infant pain and wanted information and involvement. These results provide no evidence of a reduction in NICU-related stress for parents who receive an intervention to increase their understanding and involvement in infant pain management. However, parents in the intervention group were better prepared to take an active role in infant pain care and had more positive views about their role attainment in the postdischarge period.

Pain treatment begins with a nurse’s assessment, which relies on effective assessment skills. Hospital settings have implemented pain assessment education, but there is limited evidence in pediatric transitional care settings. The purpose of this quality improvement (QI) initiative was to develop, implement, and evaluate an evidence-based pain education session with 20 nurses in a pediatric specialty hospital that provides transitional care. Specific aims were to assess nurses’ knowledge and attitudes of pain, and evaluate assessment skills based on nurses’ documentation. A prospective pre-post design with three assessments (baseline, post-intervention, and one-month follow-up) was used. The Shriner’s Pediatric Nurses’ Knowledge and Attitudes Regarding Pain questionnaire and an electronic health record review were completed at each assessment. There was significant improvement in nurses’ knowledge and attitudes of pain after the education session (F[2,6] = 50.281, p < 0.0001) from baseline to post-intervention (p < 0.0001), which was maintained at follow-up (p = 0.009). Pain assessment frequency by nurses significantly increased from 43.1% at baseline to 64.8% at post-intervention, and 67.7% at follow-up (χ²[2] = 20.55, p < 0.0001). Developmentally appropriate pain scale usage increased significantly, from 13.1% at baseline to 77.4% at post-intervention, and 81.8% at follow-up (χ²[2] = 169.19, p < 0.0001). Nursing interventions for pain increased significantly, from 33.3% at baseline to 84.0% at post-intervention, and stabilized at 80.0% at follow-up (χ²[2] = 8.91, p = 0.012). Frequency of pain reassessments did not show a statistically significant change, decreasing from 77.8% at baseline to 44.0% at post-intervention and 40.0% at follow-up (χ²[2]= 3.538, p = 0.171). Nurses’ pain knowledge and documentation of assessment skills were improved in this QI initiative.

Arthritis is characterized by pain and functional limitation affecting the patients' quality of life. We performed a clinical study to investigate the efficacy of a betamethasone valerate medicated plaster (Betesil) in improving pain and functional disability in patients with arthritis and osteoarthritis. We enrolled 104 patients affected by osteoarthritis (n = 40) or arthritis (n = 64) in different joints. Patients received diclofenac sodium cream (2 g, four times a day) or a 2.25-mg dose of Betesil applied to the painful joint every night before bedtime for 10 days. Pain and functional disability were assessed, by the Visual Analogue Scale (VAS) and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scores. Redness was assessed by clinical inspection, and edema by the "fovea sign" method. C-reactive protein (CRP) was also measured; CRP can be used to cost-effectively monitor the pharmacological treatment efficacy and is increased during the acute-phase response, returning to physiological values after tissue recovery and functional restoration. All measurements were at baseline and at 10-day follow-up. At 10-day follow-up, a greater improvement in VAS and WOMAC pain and WOMAC stiffness and functional limitation scores from baseline was observed in patients treated with Betesil compared with diclofenac (all p < 0.01). At 10-day follow-up, improvement in redness, edema, and CRP levels from baseline was also greater in patients treated with Betesil compared with diclofenac (all p < 0.01). This study demonstrates the safety and efficacy of transdermal delivery of betamethasone valerate in patients affected by arthritis and osteoarthritis.

Biobehavioral pain profile in individuals with chronic spine pain.

Matteliano, Deborah; Scherer, Yvonne Krall; Chang, Yu-Ping

Pain in the spine is the most frequently described pain problem in primary care, afflicting at least 54 million Americans. When spinal pain becomes chronic, the prognosis for recovery is poor, often leading to disability and reduced quality of life. Clinical treatment is inadequate, often focusing on physical pathology alone. To improve treatment outcomes for chronic pain as recommended by current guidelines, the Biobehavioral Pain Profile (BPP), which includes six pain response subscales, was developed to guide cognitive behavioral therapy (CBT). The purpose of this study was to describe the BPP in 100 individuals with chronic spine pain and examine the associations between the BPP and important clinical outcomes, including chronic pain, disability, and quality of life. Participants reported a high level of pain, a low quality of life, and a high level of disability despite receiving treatment with opioids. Scores on BPP subscales including evaluating loss of control, past and current experience, physiologic responsivity, and thoughts of disease progression were elevated, indicating a need for CBT. Five of the six BPP subscales had a significant association with quality of life, chronic pain, and disability with the thought of disease progression being a strong factor for most of the clinical outcome variables. By identifying BPP, clinicians can provide appropriate treatments to improve individuals' quality of life and prevent further disability. Further study using the BPP to guide CBT is needed.

Current evidence suggests it may be difficult for patients with chronic pain to quit smoking and, based on previous formative work, a 7-session individual and group-based cognitive behavioral (CB) intervention was developed. The primary aim of this randomized controlled pilot trial was to test the hypothesis that abstinence at month 6 would be greater among patients with chronic pain who received the CB intervention compared to a control condition. Upon admission to a 3-week interdisciplinary pain treatment (IPT) program, patients were randomized to receive the CB intervention (n = 30) or the control condition (n = 30). The 7-day point prevalence of self-reported smoking status was assessed at week 3 (upon completion of the 3-week IPT program) and at month 6 in an intent-to-treat analysis. At week 3, 30% (n=9) of patients in the CB condition were abstinent from smoking compared to 10% (n=3) in the control group (P=.104). At month 6, 20% (n=6) of patients who received the CB intervention were abstinent compared to none in the control group (P=.024). At week 3, a significant group by time interaction effect was found where the CB patients experienced greater improvements in self-efficacy from baseline compared to the control group (P=.002). A greater proportion of patients randomized to the CB group completed the IPT program (P=.052). The findings of this pilot trial suggest that integration of a CB-based smoking abstinence intervention into ongoing pain therapy may be an effective treatment for smokers with chronic pain.

We assessed the effectiveness of a 6-month healthy lifestyle intervention, on pain intensity in patients with chronic low back pain who were overweight or obese. We conducted a pragmatic randomised controlled trial, embedded within a cohort multiple randomised controlled trial of patients on a waiting list for outpatient orthopaedic consultation at a tertiary hospital in NSW, Australia. Eligible patients with chronic low back pain (>3 months in duration) and body mass index ≥27 kg/m and <40 kg/m were randomly allocated, using a central concealed random allocation process, to receive advice and education and referral to a 6-month telephone-based healthy lifestyle coaching service, or usual care. The primary outcome was pain intensity measured using an 11-point numerical rating scale, at baseline, 2 weeks, and monthly for 6 months. Data analysis was by intention-to-treat according to a prepublished analysis plan. Between May 13, 2015, and October 27, 2015, 160 patients were randomly assigned in a 1:1 ratio to the intervention or usual care. We found no difference between groups for pain intensity over 6 months (area under the curve, mean difference = 6.5, 95% confidence interval -8.0 to 21.0; P = 0.38) or any secondary outcome. In the intervention group, 41% (n = 32) of participants reported an adverse event compared with 56% (n = 45) in the control group. Our findings show that providing education and advice and telephone-based healthy lifestyle coaching did not benefit patients with low back pain who were overweight or obese, compared with usual care. The intervention did not influence the targeted healthy lifestyle behaviours proposed to improve pain in this patient group.

Postherpetic neuralgia (PHN) is often refractory to existing treatments. Treatment of the dorsal root ganglion (DRG) using monopolar pulsed radiofrequency (PRF), which is a non- or minimally neurodestructive technique, is not efficacious in all patients. This study aimed to determine the safety and clinical efficacy of bipolar high-voltage, long-duration PRF on the DRG in PHN patients. Self before-after controlled clinical trial. Department of Pain Medicine, the First Affiliated Hospital of China Medical University. Ninety patients diagnosed with PHN for > 3months were included. Bipolar high-voltage, long-duration PRF at 42°C for 900 seconds was applied after the induction of paresthesias covered the regions of hyperalgesic skin. The therapeutic effects were evaluated using a visual analog scale (VAS) and the 36-item Short Form health survey (SF-36) before treatment and one, 4, 8, and 12 weeks after PRF. The VAS scores at one, 4, 8, and 12 weeks after PRF treatment were significantly lower than before treatment (P < 0.001). The SF-36 scores, which included physical functioning, physical role, bodily pain, general health perceptions, vitality, social function, emotional role, and the mental health index, were significantly improved up to 12 weeks after PRF treatment (P < 0.001). No serious adverse effects were identified following treatment. The main adverse reactions included pain, tachycardia, and high blood pressure (especially when the field strength was enhanced). Single center study, relatively small number of patients, lack of a control group. Bipolar high-voltage, long-duration PRF on the DRG is an effective and safe therapeutic alternative for PHN patients. This treatment could improve the quality of life of PHN patients.

Foot pain is highly prevalent in older people and in many cases is associated with inappropriate footwear. This study evaluated the effectiveness of off-the-shelf, extra-depth footwear in reducing foot pain. Community-dwelling older people with disabling foot pain (72 men and 48 women aged 65 to 96 years; mean age 82 [SD 8]) were randomly allocated to an intervention group (n = 59) or control group (n = 61). The intervention group was provided with off-the-shelf, extra-depth footwear. Participants in the control group received their footwear at the completion of the study. Both groups continued to receive usual podiatry care for the study period. The primary outcome measure was the Foot Health Status Questionnaire (FHSQ), measured at baseline and 16 weeks. There was a significant improvement in the FHSQ pain domain (ANCOVA-adjusted mean difference 11.5 points, 95% confidence interval 4.2 to 18.8, p = .002) and FHSQ function domain (10.0 points, 0.9 to 19.1, p = .032) in the intervention group compared to the control group. The intervention group also developed fewer keratotic lesions (mean difference -1.4, -2.5 to -0.2, p = .021), were less likely to report the use of co-interventions (relative risk [RR] 0.74, 0.56 to 0.98, p = .026) and were more likely to report that their foot pain had moderately or markedly improved during the study (RR = 7.93, 2.51 to 25.00, p < .001; number needed to treat = 3, 2 to 5). Off-the-shelf, extra-depth footwear significantly reduces foot pain, improves foot function and is associated with the development of fewer keratotic lesions in older people. © The Author 2014.

Patients' changing attitudes and beliefs about pain are considered as improvements in the treatment of chronic pain. Multidisciplinary approaches to pain allow modifications of coping strategies of patients, from passive to active. We investigate how two therapeutic treatments impact patients' attitudes and beliefs regarding pain, as measured with the Survey of Pain Attitudes (SOPA). We allocated 415 patients with chronic pain either to psychoeducation combined with physiotherapy, self-hypnosis combined with self-care learning, or to control groups. Pain intensity, global impression of change, and beliefs and attitudes regarding pain were assessed before and after treatment. Our main results showed a significant effect of psychoeducation/physiotherapy on control, harm, and medical cure SOPA subscales; and a significant effect of self-hypnosis/self-care on control, disability and medical cure subscales. Correlation results showed that pain perception was negatively associated with control, while positively associated with disability, and a belief that hurt signifies harm. Patients' impression of improvement was associated with greater control, lower disability, and lower belief that hurt signifies harm. The present study showed that self-hypnosis/self-care and psychoeducation/physiotherapy were associated with patients' evolution of coping strategies from passive to active, allowing them to reduce pain perception and improve their global impression of treatment effectiveness.

Background Persistent whiplash associated disorders (WAD) have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM), conjunct motion, joint position error and ROM-variability. Methods Participants (n = 173) were recruited to three groups: 59 patients with persistent WAD, 57 patients with chronic non-traumatic neck pain and 57 asymptomatic volunteers. A 3D motion tracking system (Fastrak) was used to record maximal range of motion in the three cardinal planes of the cervical spine (sagittal, frontal and horizontal), and concurrent motion in the two associated cardinal planes relative to each primary plane were used to express conjunct motion. Joint position error was registered as the difference in head positions before and after cervical rotations. Results Reduced conjunct motion was found for WAD and chronic neck pain patients compared to asymptomatic subjects. This was most evident during cervical rotation. Reduced conjunct motion was not explained by current pain or by range of motion in the primary plane. Total conjunct motion during primary rotation was 13.9° (95% CI; 12.2–15.6) for the WAD group, 17.9° (95% CI; 16.1–19.6) for the chronic neck pain group and 25.9° (95% CI; 23.7–28.1) for the asymptomatic group. As expected, maximal cervical range of motion was significantly reduced among the WAD patients compared to both control groups. No group differences were found in maximal ROM-variability or joint position error. Conclusion Altered movement patterns in the cervical spine were found for both pain groups, indicating changes in motor control strategies. The changes were not related to a history of neck trauma, nor

TREATMENT of patients with chronic low back pain (CLBP) aims to reduce disability, improve functional capacity, and participation. Time contingent prescription of analgesics is a treatment modality in CLBP. The impact of analgesics on functional capacity is unknown. Aim of the study was to explore the effect of analgesics on functioning measured by functional capacity evaluation, and self-reported disability in patients with CLBP. Explorative Randomized Placebo-Controlled Clinical Trial was performed in an outpatient pain rehabilitation setting on patients waiting for rehabilitation. Included patients had low back pain lasting >3 months, visual analogue scale worst pain ≥4.0 cm, and age >18 years. Outcome measures before (T0) and after treatment (T1): functional capacity, pain intensity, Roland Morris Disability Questionnaire. T1: global perceived pain relief. Patient characteristics and psychological questionnaires were assessed. Fifty patients were included in this study and were randomly assigned to 2 weeks treatment or placebo. acetaminophen/tramadol 325 mg/37.5 mg per capsule. Dose: maximum acetaminophen 1,950 mg and tramadol 225 mg per day; treatment and placebo titrated identically. Compliance and side-effects were monitored. TREATMENT effects between groups over time were compared. One patient (treatment group) was lost to follow-up. Forty-nine patients remained in the study. TREATMENT effects in primary outcomes did not differ significantly between groups. A subgroup of 10 (42%) patients (treatment group) reported global pain relief (responders) who reduced self-reported disability (p < 0.05). Responders had significantly lower catastrophizing scores. Overall treatment effects were small and non-significant. A subgroup, however, reported improved functioning as a result of treatment. Responders had lower catastrophizing scores.

Chronic axial low-back pain is a debilitating disorder that impacts all aspects of an afflicted individual's life. Effective, durable treatments have historically been elusive. Interventional therapies, such as spinal cord stimulation (SCS), have shown limited efficacy at best. Recently, a novel treatment, 10 kHz SCS, has demonstrated superior pain relief compared with traditional SCS in a randomized controlled trial (RCT). In this manuscript, we report on the long-term improvements in quality of life (QoL) outcomes for subjects enrolled in this study. A prospective, multicenter, randomized controlled trial (SENZA-RCT) was conducted. Patients with both chronic back and leg pain were enrolled and randomized (1:1) into 10 kHz SCS or traditional SCS treatment groups. A total of 171 subjects received a permanent SCS device implant. QoL and functionality measures were collected up to 12 months. The device remote control utilization, which is an indication of patient interaction with the device for adjustments, was collected at 24-month post-implantation. At 12 months, a higher proportion of 10 kHz SCS subjects had marked improvement of their disability (Oswestry Disability Index) to a "moderate" or "minimal" impact on their daily function versus the control group. The subjects also reported better improvement in the Global Assessment of Functioning, Clinician Global Impression of Change, Pittsburgh Sleep Quality Index, and short-form McGill Pain Questionnaire, compared to traditional SCS subjects. The 10 kHz SCS subjects also reported far higher rates of both driving and sleeping with their device turned on, as well as reduced reliance on their programmers to adjust therapy settings. In addition to superior pain relief, 10 kHz SCS provides long-term improvements in quality of life and functionality for subjects with chronic low-back and leg pain.

To test the feasibility, acceptability, and effects of a home-based morning versus evening bright light treatment on function and pain sensitivity in women with fibromyalgia. A single blind randomized study with two treatment arms: 6 days of a 1 hour morning light treatment or 6 days of a 1 hour evening light treatment. Function, pain sensitivity, and circadian timing were assessed before and after treatment. Participants slept at home, except for two nights in Sleep Center. Ten women meeting the American College of Rheumatology's diagnostic criteria for fibromyalgia, including normal blood test results. Self-reported function was assessed with the Fibromyalgia Impact Questionnaire (FIQ). Pain sensitivity was assessed using a heat stimulus that gave measures of threshold and tolerance. Circadian timing was assessed with the dim light melatonin onset. Both morning and evening light treatments led to improvements in function and pain sensitivity. However, only the morning light treatment led to a clinically meaningful improvement in function (>14% reduction from baseline FIQ) and morning light significantly increased pain threshold more than evening light ( P  < 0.05). Phase advances in circadian timing were associated with an increase in pain tolerance (r = 0.67, P  < 0.05). Bright light treatment appears to be a feasible and acceptable adjunctive treatment to women with fibromyalgia. Those who undergo morning light treatment may show improvements in function and pain sensitivity. Advances in circadian timing may be one mechanism by which morning light improves pain sensitivity. Findings can inform the design of a randomized controlled trial. © 2016 American Academy of Pain Medicine. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com

Many strategies for labor pain management have been studied, including aromatherapy, which is a noninvasive, alternative medicine used as an adjunct for labor pain control. Nevertheless, the results were contradictory. Therefore, we conducted this study to determine the effectiveness of aromatherapy for reducing pain during labor. A randomized controlled trial was carried out on Thai laboring primigravidae who were a low-risk singleton pregnancy undergoing vaginal delivery. All participants, both study and control group, received standard obstetric care. Aromatherapy was only provided to the study group during the first stage of labor. The women rated their pain intensity by rating scales at different stages of labor. The primary outcome was pain scores and the secondary outcomes were necessity of painkiller usage, labor time, aromatherapy-associated complications, route of delivery, and Apgar scores. A total of 104 women were recruited, 52 in each group. Baseline characteristics and baseline pain scores were comparable. The median pain score of latent and early active phase was lower in the aromatherapy group, 5 vs 6 and 7 vs 8, respectively. The mean differences of pain scores between latent and early active phase and the baseline were significantly lower in the aromatherapy group, 1.88 vs 2.6 (p = 0.010) and 3.82 vs 4.39 (p = 0.031), respectively. Late active phase pain scores and other perinatal outcomes were not significantly different. Aromatherapy is helpful in reducing pain in latent and early active phase, and can probably be used as an adjunctive method for labor pain control without serious side effects.

Abstract This randomized controlled trial was performed to investigate whether placebo effects in chronic low back pain could be harnessed ethically by adding open-label placebo (OLP) treatment to treatment as usual (TAU) for 3 weeks. Pain severity was assessed on three 0- to 10-point Numeric Rating Scales, scoring maximum pain, minimum pain, and usual pain, and a composite, primary outcome, total pain score. Our other primary outcome was back-related dysfunction, assessed on the Roland–Morris Disability Questionnaire. In an exploratory follow-up, participants on TAU received placebo pills for 3 additional weeks. We randomized 97 adults reporting persistent low back pain for more than 3 months' duration and diagnosed by a board-certified pain specialist. Eighty-three adults completed the trial. Compared to TAU, OLP elicited greater pain reduction on each of the three 0- to 10-point Numeric Rating Scales and on the 0- to 10-point composite pain scale (P < 0.001), with moderate to large effect sizes. Pain reduction on the composite Numeric Rating Scales was 1.5 (95% confidence interval: 1.0-2.0) in the OLP group and 0.2 (−0.3 to 0.8) in the TAU group. Open-label placebo treatment also reduced disability compared to TAU (P < 0.001), with a large effect size. Improvement in disability scores was 2.9 (1.7-4.0) in the OLP group and 0.0 (−1.1 to 1.2) in the TAU group. After being switched to OLP, the TAU group showed significant reductions in both pain (1.5, 0.8-2.3) and disability (3.4, 2.2-4.5). Our findings suggest that OLP pills presented in a positive context may be helpful in chronic low back pain. PMID:27755279

(1) To evaluate the influence of local cold on severity of labour pain and (2) to identify the effect of local cold on maternal and neonatal outcomes. Fear of labour pain results in an increase in pain and duration of labour, maternal discontent and demand for caesarean section. Regarding maternal and foetal complications of analgesic medications, the attention to application of nonpharmacological methods including cold therapy is increased. Randomised controlled trial. Sixty-four pregnant women, at initiation of active phase of labour, were allocated randomly to cold therapy and control groups (n = 64). Null parity, term pregnancy, presence of single foetus, cephalic presentation and completing informed consent were considered as inclusion criteria. Administration of analgesic and anaesthesia, foetal distress, skin lesions in regions of cold therapy and high-risk pregnancy provided exclusion criteria. Cold pack was applied over abdomen and back, for 10 minutes every 30 minutes during first phase of labour. Additionally, cold pack was placed over perineum, for 5 minutes every 15 minutes during second phase. Pain severity was assessed based on the visual analogue scale. The two groups were not significantly different considering demographic data, gestational age, foetal weight, rupture of membranes and primary severity of pain. Degree of pain was lower in cold therapy group during all parts of active phase and second stage. Duration of all phases was shorter in cold therapy group in all phases. Foetal heart rate, perineal laceration, type of birth, application of oxytocin and APGAR score were not significantly different between two groups. Labour pain is probably reduced based on gate theory using cold. Pain control by cold maybe improves labour progression without affecting mother and foetus adversely. Local cold therapy could be included in labour pain management. © 2013 John Wiley & Sons Ltd.

Most adults undergoing cardiac surgery suffer from moderate to severe pain for up to 6 days after surgery. Individual barriers and attitudes regarding pain and its relief make patients reluctant to report their pain and ask for analgesic medication, which results in inadequate pain management. More innovative educational interventions for postoperative pain relief are needed. We developed a Web-based nursing intervention to influence patient's involvement in postoperative pain management. The intervention (SOULAGE-TAVIE) includes a preoperative 30-minute Web-based session and 2 brief face-to-face postoperative booster sessions. The Web application generates reflective activities and tailored educational messages according to patients' beliefs and attitudes. The messages are transmitted through videos of a virtual nurse, animations, stories, and texts. The aim of this single-blinded pilot randomized trial was to investigate the preliminary effects of a virtual nursing intervention (SOULAGE-TAVIE) to improve pain relief in patients undergoing cardiac surgery. Participants (N = 60) were adults scheduled for their first cardiac surgery. They were randomly assigned to the experimental group using SOULAGE-TAVIE (n = 30) or the control group using usual care, including an educational pamphlet and postoperative follow-up (n = 30). Data were collected through questionnaires at the time of admission and from day 1 to day 7 after surgery with the help of a blinded research assistant. Outcomes were pain intensity, pain interference with daily activities, patients' pain barriers, tendency to catastrophize in face of pain, and analgesic consumption. The two groups were comparable at baseline across all demographic measures. Results revealed that patients in the experimental group did not experience less intense pain, but they reported significantly less pain interference when breathing/coughing (P = .04).
