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.

Most, if not all, cancer patients require care from community teams at some stage during their disease trajectory. For many of these patients, community nurses and General Practitioners are the main point of contact. Pain is reported by between 55-95% of patients with advanced or terminal disease. Optimal pain control positively impacts on the physical, emotional and functional well-being of the patient. Despite the existence of guidelines (WHO, 1996) (SIGN, 2000) and a wealth of literature on cancer pain management, half of all patients in Western countries still do not receive adequate pain relief. This article looks at the reasons behind this and provides community nurses with an overview of up-to-date information on pain pathophysiology and management, so that the control of cancer pain can be optimized in the community.

Little is known about the impact of translation of pain management clinical practice guidelines on pain control in paediatrics. In an effort to overcome this, a longitudinal, nation-wide, multi-centre paediatric quality improvement (QI) study was initiated by the German Society of Pediatric Haematology and Oncology (GPOH) entitled Schmerz-Therapie in der Onkologischen Paediatrie (STOP). The project's primary major aims were to improve paediatric oncology pain control in Germany, and to evaluate the project's impact on the pain management quality. To achieve these aims, STOP encompassed six sequential phases to evaluate present practice, develop recommendations for practical pain control, actively engage participants in improvement strategies, and assess change. The purpose of this paper is to briefly describe STOP in its entirety, report on comparisons between active quality management (QM) departments that actively participated in the project and non-active QM departments regarding differences in pain control, patients' and parents' perspectives on pain control and health professionals' knowledge, and to discuss the impact of STOP as a whole. Four hypotheses were examined: (1) changes in health care professionals' knowledge on pain in paediatric oncology and pain management after a three-year period (2) impact of active participation in the STOP-project; (3) differences in patients' and parents' perspective in active QM versus non-active QM departments; (4) impact of the STOP-project on the health care professionals' knowledge in active QM versus non-active QM departments. Data included surveys, interviews, and standardised pre-/post-intervention documentation of pain control. All German paediatric oncology departments were invited to participate. The prime means of intervention was education (printed material, passive participation; additional lectures and feed-back, active participation). Quality indicators were defined and compared with regards to the four

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.

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

Myofascial pain syndrome is defined as subacute or chronic pain with sensory, motor and autonomic symptoms referred from active trigger points with associated painful dysfunctions. Authors present the usefulness of botulinum toxin A or B (BoNT/A or BoNT/B) injected into target muscles since the toxin is capable of controlling not only the muscular spasm but mostly the pain by alternative mechanisms of action, which are discussed. Posology of BoNT, technical aspects and results are presented. BoNT represents an interesting and useful tool for an adequate management of patients with myofascial pain.

Postoperative pain management techniques in hip and knee arthroplasty.

Adequate control of postoperative pain following hip and knee arthroplasty can be a challenging task fraught with potential complications. Postoperative pain is perceived by the patient via a complex network and a multitude of molecular messengers in both the peripheral and central nervous systems. This allows the physician to modulate pain via an array of medications that act on different sites within the body. Using both contemporary and traditional pain modulators, the delivery and timing of these medications can affect postoperative pain and, ultimately, rehabilitation of the arthroplasty patient. Current techniques for controlling pain use both multimodal and preemptive analgesia to improve the outcome of the surgery while minimizing the potential adverse effects of the medications given.

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

Our institution's traditional pain management strategy after shoulder arthroplasty has involved the utilization of postoperative patient-controlled narcotic analgesia. More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. Patients undergoing primary total shoulder or reverse arthroplasty were retrospectively studied. All patients underwent interscalene brachial plexus blockade. "Traditional" patients were provided a patient-controlled analgesic pump postoperatively. TLC patients were given preoperative and postoperative multimodal, non-narcotic analgesic medications and breakthrough narcotics. Morphine equivalent units (MEU) consumed and Visual Analog Scale (VAS) scores for pain (0, 8, 16, and 24 hours) were considered. There were 108 patients in each group. Total postoperative narcotic consumption in the first 24 postoperative hours was 38.5 +/- 81.1 MEU in the "Traditional group" compared to 59.3 +/- 59.1 MEU in the TLC group ( P<0.001 ). Of patients in the TLC group, 88% utilized breakthrough narcotics. VAS pain was significantly higher in the "Traditional group" at 16 hours (4.1 +/- 2.9 vs 3.2 +/- 2.7, P=0.020 ) and 24 hours (4.8 +/- 2.7 vs 3.7 +/- 2.6, P=0.004 ). Those treated with the TLC protocol had greater narcotic utilization but better VAS pain scores at 24 hours after surgery. Both groups experienced rebound pain. While the TLC protocol led to an improved pain experience, further modification of the currently protocol may be necessary to reduce overall narcotic utilization.

Resection Arthroplasty Compared With Total Hip Arthroplasty in Treating Chronic Hip Pain of Patients With a History of Substance Abuse.

2018-03-16

Retrospective comparison of surgical management of severe hip pain in patients with a history of substance abuse treated by modified Girdlestone resection arthroplasty (RA) vs delayed total hip arthroplasty (THA) following yearlong sobriety pathway. Patients were identified using charts, current procedural terminology (CPT) code query, and THA sobriety pathway registry. The primary outcome was adequate pain control following surgery, defined as visual analog scale ≤ 5 or verbal description of "moderate" or lower pain. RA patients with infectious arthritis were analyzed separately. The secondary outcome was the level of mobility after surgery. In the THA pathway, 15 of 28 (53.6%) proved sobriety, 11 (39.3%) underwent THA, and 9 (32.1%) achieved adequate pain control (median 77 days). After RA, 19 (76%) achieved adequate pain control (median 119.5 days). Preoperative infection did not significantly affect time to pain control after RA (P = .94). Time to adequate pain control was not significantly different between RA and THA patients (P = .19). Three patients (30%) experienced improved level of mobility after THA and 7 (70%) experienced no change. After RA, 7 patients (29.1%) experienced improved level of mobility, 3 (13.6%) lost mobility, and 14 (63.6%) experienced no change. Three RA patients were later converted to THA without complication. Yearlong sobriety pathway leading to THA leads to successful pain control in less than one-third of enrolled patients. Compared to delayed THA, RA enables more patients with substance abuse to be treated sooner and results in successful reduction of pain in a similar proportion of patients. RA may be an effective pain-reducing procedure for these patients. Copyright © 2018 Elsevier Inc. All rights reserved.

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.

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®.

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.

Accurate proprioception is critical while walking, yet an ambulatory epidural regimen that provides adequate analgesia for labour while simultaneously preserving proprioceptive input has not been described. Sixty primigravidae in established labour received bupivacaine 15 mg (15 ml of 0.1% w/v) and fentanyl 100 micrograms through a lumbar epidural catheter. Clinical assessment of dorsal column sensory function included: vibration sense, distal proprioception and the Romberg test, and were all performed before catheter insertion and 30 min after the study bolus. Sensory modalities were also tested compared to an unblocked dermatome. Pain was scored on a 0-10 cm visual analogue scale (VAS) before and 30 min after induction. Intensity of the motor block was tested using a modified Bromage score (grade 1-6). The study bolus provided reliable analgesia with 43 parturients attaining a VAS pain score of zero. Mean duration of analgesia was 67.5 min (SD 22.85). All parturients retained the ability to perform a partial knee bend while standing (grade 6). No mothers exhibited impaired distal proprioception, altered vibration sense or a positive Romberg sign. This study confirms that the addition of lumbar epidural fentanyl 100 micrograms to 15 mg of epidural bupivacaine provides good control of labour pain with no motor block and establishes that this combination preserves dorsal column sensory function.

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.

This study aimed to determine whether a non-penetrating sham needle can serve as an adequate sham control. We conducted a randomised, subject-blind, sham-controlled trial in both acupuncture-naïve and experienced healthy volunteers. Participants were randomly allocated to receive either real acupuncture (n=39) or non-penetrating sham acupuncture (n=40) on the hand (LI4), abdomen (CV12) and leg (ST36). The procedures were standardised and identical for both groups. Participants rated acupuncture sensations on a 10-point scale. A blinding index was calculated based on the participants' guesses on the type of acupuncture they had received (real, sham or do not know) for each acupuncture point. The association of knowledge about and experience in acupuncture with correct guessing was also examined. The subjects in both groups were similar with respect to age, gender, experience or knowledge about acupuncture. The sham needle tended to produce less penetration, pain and soreness only at LI4. Blinding appeared to be successfully achieved for ST36. Although 41% of participants in the real acupuncture group made correct guesses for LI4, 31% guessed incorrectly for CV12, beyond chance level. People with more experience and knowledge about acupuncture were more likely to correctly guess the type of needle they received at ST36 only, compared to that at the other points. A non-penetrating sham needle may successfully blind participants and thus, may be a credible sham control. However, the small sample size, the different needle sensations, and the degree and direction of unblinding across acupuncture points warrant further studies in Korea as well as other countries to confirm our finding. Our results also justify the incorporation of formal testing of the use of sham controls in clinical trials of acupuncture. Copyright © 2010 Elsevier Ltd. All rights reserved.

[A multimodal and multidisciplinary postoperative pain management concept].

Ettrich, U; Seifert, J; Scharnagel, R; Günther, K P

2007-06-01

Under-treatment of acute postoperative pain can lead to chronic pain with neuronal plasticity and result in poor surgical outcomes. A multimodal approach is therefore necessary to reduce postoperative pain by combining various analgesics with a non-pharmacological strategy. The current use of multimodal approaches, even for the management of postoperative pain, can reduce the side effects of pharmaceutical therapy alone as well as reducing the length of hospital stay. Adequate pain control is an important prerequisite for the application of rehabilitation programmes and will thereby influence functional outcome. In addition, patient satisfaction, as a major benchmarking factor after surgical treatment, is significantly influenced by the quality of postoperative pain management.

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.

Background Chronic knee pain, most commonly caused by knee osteoarthritis, is a prevalent condition which in most cases can be effectively treated through conservative, non-surgical care involving exercise therapy, education, psychosocial support, and weight loss. However, most people living with chronic knee pain do not receive adequate care, leading to unnecessary use of opiates and surgical procedures. Objective Assess the efficacy of a remotely delivered digital care program for chronic knee pain. Methods We enrolled 162 participants into a randomized controlled trial between January and March 2017. Participants were recruited from participating employers using questionnaires for self-assessment of their knee pain, and randomized into treatment (n=101) and control (n=61) groups. Participants in the treatment group were enrolled in the Hinge Health digital care program for chronic knee pain. This is a remotely delivered, home-based 12-week intervention that includes sensor-guided exercise therapy, education, cognitive behavioral therapy, weight loss, and psychosocial support through a personal coach and team-based interactions. The control group received three education pieces regarding self-care for chronic knee pain. Both groups had access to treatment-as-usual. The primary outcome was the Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain subscale and KOOS Physical Function Shortform (KOOS-PS). Secondary outcomes were visual analog scales (VAS) for pain and stiffness respectively, surgery intent, and self-reported understanding of the condition and treatment options. Outcome measures were analyzed by intention to treat (excluding 7 control participants who received the digital care program due to administrative error) and per protocol. Results In an intent-to-treat analysis the digital care program group had a significantly greater reduction in KOOS Pain compared to the control group at the end of the program (greater reduction of 7.7, 95% CI 3.0 to 12

The present article reviews, through a case-based presentation, the nonpharmacological and pharmacological methods used to ensure adequate pain control in children facing end of life. Details on the impressive range of opioid dosages required and routes of administration are highlighted from published literature and clinical experience. Where available, evidence-based recommendations are provided. Potential side effects of pain medication and barriers to good pain control are discussed. Novel analgesics and innovative delivery methods are presented as future tools enhancing pain relief at the end of life. Some challenges to ethically grounded research in this important context of care are reviewed. PMID:16960633

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.

Rib fractures are common in trauma admissions and are associated with an increased risk of pulmonary complications, intensive care unit admissions, and mortality. Providing adequate pain control in patients with multiple rib fractures decreases the risk of adverse events. Thoracic epidural analgesia is currently the preferred method for pain control. This study compared outcomes in patients with multiple acute rib fractures treated with posterior paramedian subrhomboidal (PoPS) analgesia versus thoracic epidural analgesia (TEA). This prospective study included 30 patients with three or more acute rib fractures admitted to a Level I trauma center. Thoracic epidural analgesia or PoPS catheters were placed, and local anesthesia was infused. Data were collected including patients' pain level, adjunct morphine equivalent use, adverse events, length of stay, lung volumes, and discharge disposition. Nonparametric tests were used and two-sided p < 0.05 were considered statistically significant. Nineteen (63%) of 30 patients received TEA and 11 (37%) of 30 patients received PoPS. Pain rating was lower in the PoPS group (2.5 vs. 5; p = 0.03) after initial placement. Overall, there was no other statistically significant difference in pain control or use of oral morphine adjuncts between the groups. Hypotension occurred in eight patients, 75% with TEA and only 25% with PoPS. No difference was found in adverse events, length of stay, lung volumes, or discharge disposition. In patients with rib fractures, PoPS analgesia may provide pain control equivalent to TEA while being less invasive and more readily placed by a variety of hospital staff. This pilot study is limited by its small sample size, and therefore additional studies are needed to prove equivalence of PoPS compared to TEA. Therapeutic study, level IV.

Opioid receptors and their ligands in the musculoskeletal system and relevance for pain control.

Interest in opioid drugs like morphine, as the oldest and most potent pain-killing agents known, has been maintained through the years. One of the most frequent chronic pain sensations people experience is associated with pathological conditions of the musculoskeletal system. Chronic musculoskeletal pain is a major health problem, and an adequate management requires understanding of both peripheral and central components, with more attention drawn to the former. Intense experimental and clinical research activities resulted in important knowledge on the mechanisms and functions of the endogenous opioid system located in the periphery. This review describes the occurrence and distribution of endogenous opioids and their receptors in the musculoskeletal system, and their role in pain control in musculoskeletal disorders, such as rheumatoid arthritis and osteoarthritis. Using different techniques, including immunohistochemistry, electron microscopy or radioimmunoassay, expression of enkephalins, dynorphin, β-endorphin, and endomorphins was demonstrated in musculoskeletal tissues of animals and humans. Localization of opioid peptides was found in synovial membrane, periosteum, bone and bone marrow, loose connective tissue, the paratenon and musculotendinous junction of the achilles tendon. Animal and human studies have also demonstrated expression of µ, δ and κ opioid receptor proteins in musculoskeletal tissues using radioligand binding assays, autoradiography, electrophysiology, immunohistochemistry and Western blotting. Opioid receptor gene expression was reported based on polymerase chain reaction and in situ hybridization techniques. Combining morphological and quantitative approaches, important evidence that the musculoskeletal apparatus is equipped with a peripheral opioid system is provided. Demonstration of the occurrence of an endogenous opioid system in bone and joint tissues represents an essential step for defining novel pharmacological strategies to

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 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

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.

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.

Sickle cell crisis, or vaso-occlusive crisis (VOC), is a major cause of hospitalizations for adults and children with sickle cell disease, and is associated with increased morbidity and mortality. Despite prompt pharmacological treatment and multimodal pain management, acute pain during a VOC is often not adequately controlled in the pediatric population. We placed a continuous popliteal sciatic nerve block under ultrasound guidance in a pediatric patient for localized refractory pain during a VOC, resulting in improved pain control with preserved sensorimotor function.

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.

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.

Chronic pain has become a major health problem across the world, especially in older adults. Unfortunately, the effectiveness of medical interventions is modest. Some have argued that assessment strategies should be improved if the impact of medical interventions is to be improved. Ecological momentary assessment using smartphones is now considered the gold standard in monitoring in health settings, including chronic pain. However, to the best of our knowledge, there is no randomized controlled trial to show that telemonitoring using a smartphone app can indeed improve the effectiveness of medical treatments in adults with chronic pain. The goal of this study will be to explore the effects of using a smartphone app for telemonitoring adults with chronic pain. The study will be a randomized controlled trial with three groups: treatment as usual (TAU), TAU+app, and TAU+app+alarms. All groups will receive the adequate treatment for their pain, which will be prescribed the first day of study according to clinical guidelines. Assessment in the TAU group will be the usual at the Pain Clinic, that is, a paper-and-pencil evaluation at the onset of treatment (beginning of study) and at follow up (end of study, 30 days later). The other two groups (TAU+app and TAU+app+alarms) will be assessed daily using Pain Monitor, a smartphone app developed by our multidisciplinary team. Telemonitoring will only be made in the TAU+app+alarms group. For this group, physicians at the Pain Clinic may decide to adjust pain treatment in response to alarms. Telemonitoring is not the usual practice at the Pain Clinic and will not occur in the other two groups (TAU and TAU+app), so no changes in treatment are expected in these groups after the first appointment. The total sample size will be 150, with 50 patients in each group. The assessment protocol will be the same in all groups and will include pain intensity and side effects of the medication (primary outcomes), together with several pain

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.

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.

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.

Complementary and alternative treatment of musculoskeletal pain.

PubMed

Grazio, Simeon; Balen, Diana

2011-12-01

The use of complementary and alternative medicine (CAM) is high and increasing worldwide. Patients usually use CAM in addition to conventional medicine, mainly to treat pain. In a large number of cases, people use CAM for chronic musculoskeletal pain as in osteoarthritis, back pain, neck pain, or fibromyalgia. Herewith, a review is presented of CAM efficacy in treating musculoskeletal pain for which, however, no scientific research has so far provided evidence solid enough. In some rare cases where adequate pain control cannot be achieved, CAM might be considered in rational and individual approach based on the first general rule in medicine "not to harm" and on the utility theory of each intervention, i.e. according to the presumed mechanism of painful stimulus and with close monitoring of the patient's response. Further high quality studies are warranted to elucidate the efficacy and side effects of CAM methods. Therefore, conventional medicine remains the main mode of treatment for patients with musculoskeletal painful conditions.

Background Soft tissue injuries commonly present to the emergency department (ED), often with acute pain. They cause significant suffering and morbidity if not adequately treated. Paracetamol and ibuprofen are commonly used analgesics, but it remains unknown if either one or the combination of both is superior for pain control. Objectives To investigate the analgesic effect of paracetamol, ibuprofen and the combination of both in the treatment of soft tissue injury in an ED, and the side effect profile of these drugs. Methods Double-blind, double dummy, placebo-controlled randomised controlled trial. 782 adult patients presenting with soft tissue injury without obvious fractures attending the ED of a university hospital in the New Territories of Hong Kong were recruited. Patients were randomised using a random number table into three parallel arms of paracetamol only, ibuprofen only and a combination of paracetamol and ibuprofen in a 1:1:1 ratio. The primary outcome measure was pain score at rest and on activity in the first 2 hours and first 3 days. Data was analysed on an intention to treat basis. Results There was no statistically significant difference in pain score in the initial two hours between the three groups, and no clinically significant difference in pain score in the first three days. Conclusion There was no difference in analgesic effects or side effects observed using oral paracetamol, ibuprofen or a combination of both in patients with mild to moderate pain after soft tissue injuries attending the ED. Trial registration The study is registered with ClinicalTrials.gov (no. NCT00528658). PMID:29408866

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.

Background. Opioid analgesics are included in treatment guidelines for the symptomatic management of osteoarthritis (OA). Starting with a low dose of opioid and slowly titrating to a higher dose may help avoid intolerable side effects. Methods. Subjects aged ≥40 years, with moderate to severe pain induced by OA of the hip or knee not adequately controlled by previous non-steroidal anti-inflammatory drugs (NSAIDs) or paracetamol treatment, were enrolled. Subjects received OROS hydromorphone 4 mg or placebo once-daily. The dose was titrated every 3-4 days in case of unsatisfactory pain control during the 4-week titration phase. A 12 week maintenance phase followed. The primary efficacy endpoint was the change in “pain on average” measured on the Brief Pain Inventory (BPI) scale from baseline to the end of the maintenance phase. Results. 139 subjects received OROS hydromorphone and 149 subjects received placebo. All efficacy endpoints showed similar improvements from baseline to end of study in the 2 groups. The safety results were consistent with the safety profile of OROS hydromorphone. Conclusion.The study did not meet the primary endpoint; although many subjects' pain was not adequately controlled at inclusion, their pain may have improved with continued paracetamol or NSAID treatment.

Pain remains highly prevalent in HIV-seropositive (HIV+) patients despite their well-suppressed viremia with combined antiretroviral therapy. Investigating brain abnormalities within the pain matrix, and in relation to pain symptoms, in HIV+ participants may provide objective biomarkers and insights regarding their pain symptoms. We used Patient-Reported Outcome Measurement Information System (PROMIS®) pain questionnaire to evaluate pain symptoms (pain intensity, pain interference and pain behavior), and structural MRI to assess brain morphometry using FreeSurfer (cortical area, cortical thickness and subcortical volumes were evaluated in 12 regions within the pain matrix). Compared to seronegative (SN) controls, HIV+ participants had smaller surface areas in prefrontal pars triangularis (right: p = 0.04, left: p = 0.007) and right anterior cingulate cortex (p = 0.03) and smaller subcortical regions (thalamus: p ≤ 0.003 bilaterally; right putamen: p = 0.01), as well as higher pain scores (pain intensity-p = 0.005; pain interference-p = 0.008; pain-behavior-p = 0.04). Furthermore, higher pain scores were associated with larger cortical areas, thinner cortices and larger subcortical volumes in HIV+ participants; but smaller cortical areas, thicker cortices and smaller subcortical volumes in SN controls (interaction-p = 0.009 to p = 0.04). These group differences in the pain-associated brain abnormalities suggest that HIV+ individuals have abnormal pain responses. Since these abnormal pain-associated brain regions belong to the affective component of the pain matrix, affective symptoms may influence pain perception in HIV+ patients and should be treated along with their physical pain symptoms. Lastly, associations of lower pain scores with better physical or mental health scores, regardless of HIV-serostatus (p < 0.001), suggest adequate pain treatment would lead to better quality of life in all participants.

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 evaluate the impact of an extended-release, once-daily morphine sulfate formulation on depressive symptoms and neurocognition in patients with chronic nonmalignant pain. Prospective, open-label, one-group trial with a pretest-posttest design. Outpatient pain management clinic. Chronic nonmalignant pain patients inadequately controlled with short-acting opioid analgesics and eligible for treatment with once-daily morphine sulfate were initiated on a dose at or near the morphine-equivalent dose of the short-acting regimen. The following assessments were made at baseline and 4 weeks after initiating intervention: pain intensity, pain unpleasantness, pain suffering, pain behaviors, Beck Depression Inventory, and cognitive function. Eighty-four patients provided usable data. Pain intensity, unpleasantness, and suffering scores were significantly reduced at follow-up (P = 0.001). The mean Beck Depression Inventory scores were significantly lower at follow-up (P = 0.001). Significant improvements were seen in scores at follow-up on the three validated neurocognitive tests: the digit span test, the digit symbol substitution test, and the paced auditory serial addition test (P = 0.001). Achieving adequate pain control with once-daily morphine was associated with a reduction in pain and improvements in depressive symptoms and cognitive functioning in the short term.

Despite accumulating evidence that procedural pain experienced by newborn infants may have acute and even long-term detrimental effects on their subsequent behaviour and neurological outcome, pain control and prevention remain controversial issues. Our aim was to develop guidelines based on evidence and clinical practice for preventing and controlling neonatal procedural pain in the light of the evidence-based recommendations contained in the SIGN classification. A panel of expert neonatologists used systematic review, data synthesis and open discussion to reach a consensus on the level of evidence supported by the literature or customs in clinical practice and to describe a global analgesic management, considering pharmacological, non-pharmacological, behavioural and environmental measures for each invasive procedure. There is strong evidence to support some analgesic measures, e.g. sucrose or breast milk for minor invasive procedures, and combinations of drugs for tracheal intubation. Many other pain control measures used during chest tube placement and removal, screening and treatment for ROP, or for postoperative pain, are still based not on evidence, but on good practice or expert opinions. Conclusion: These guidelines should help improving the health care professional's awareness of the need to adequately manage procedural pain in neonates, based on the strongest evidence currently available.

We conducted a systematic review and meta-analysis analysing the existing data on transcutaneous electrical nerve stimulation (TENS) or interferential current (IFC) for chronic low back pain (CLBP) and/or neck pain (CNP) taking into account intensity and timing of stimulation, examining pain, function and disability. Seven electronic databases were searched for TENS or IFC treatment in non-specific CLBP or CNP. Four reviewers independently selected randomized controlled trials (RCTs) of TENS or IFC intervention in adult individuals with non-specific CLBP or CNP. Primary outcomes were for self-reported pain intensity and back-specific disability. Two reviewers performed quality assessment, and two reviewers extracted data using a standardized form. Nine RCTs were selected (eight CLBP; one CNP), and seven studies with complete data sets were included for meta-analysis (655 participants). For CLBP, meta-analysis shows TENS/IFC intervention, independent of time of assessment, was significantly different from placebo/control (p < 0.02). TENS/IFC intervention was better than placebo/control, during therapy (p = 0.02), but not immediately after therapy (p = 0.08), or 1-3 months after therapy (p = 0.99). Analysis for adequate stimulation parameters was not significantly different, and there was no effect on disability. This systematic review provides inconclusive evidence of TENS benefits in low back pain patients because the quality of the studies was low, and adequate parameters and timing of assessment were not uniformly used or reported. Without additional high-quality clinical trials using sufficient sample sizes and adequate parameters and outcome assessments, the outcomes of this review are likely to remain unchanged. These data highlight the need for additional high-quality RCTs to examine the effects of TENS in CLBP. Trials should consider intensity of stimulation, timing of outcome assessment and assessment of pain, disability and function. © 2017

There is evidence that education on pain physiology can have positive effects on pain, disability, and catastrophization in patients with chronic musculoskeletal pain disorders. A double-blind randomized controlled trial (RCT) was performed to examine whether intensive pain physiology education is also effective in fibromyalgia (FM) patients, and whether it is able to influence the impaired endogenous pain inhibition of these patients. Thirty FM patients were randomly allocated to either the experimental (receiving pain physiology education) or the control group (receiving pacing self-management education). The primary outcome was the efficacy of the pain inhibitory mechanisms, which was evaluated by spatially accumulating thermal nociceptive stimuli. Secondary outcome measures included pressure pain threshold measurements and questionnaires assessing pain cognitions, behavior, and health status. Assessments were performed at baseline, 2 weeks, and 3 months follow-up. Repeated measures ANOVAS were used to reveal possible therapy effects and effect sizes were calculated. After the intervention the experimental group had improved knowledge of pain neurophysiology (P<0.001). Patients from this group worried less about their pain in the short term (P=0.004). Long-term improvements in physical functioning (P=0.046), vitality (P=0.047), mental health (P<0.001), and general health perceptions (P<0.001) were observed. In addition, the intervention group reported lower pain scores and showed improved endogenous pain inhibition (P=0.041) compared with the control group. These results suggest that FM patients are able to understand and remember the complex material about pain physiology. Pain physiology education seems to be a useful component in the treatment of FM patients as it improves health status and endogenous pain inhibition in the long term.

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.

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.

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.

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.

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.

Parenting in the context of chronic pain: A controlled study of parents with chronic pain

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

In the United States, chronic pain is experienced by over 39.4 million adults, many of whom are treated with opioid pain medications. This research presents an interpretation of the experience of seeking pain relief for a group of people taking opioid pain medications whose pain is not adequately controlled. A concurrent embedded mixed-methods design was used, including a Heideggerian hermeneutic qualitative approach that focuses on the participants' perceptions as a vehicle for understanding the phenomenon of seeking pain relief with descriptive quantitative data in a supporting role. Thirteen interviews and 15 surveys were analyzed, all of which met the following criteria: (1) self-reported chronic pain (persistent pain lasting a minimum of six months), (2) current use of prescription opioid medications, (3) pain not successfully controlled. The analysis revealed a paradox, which we describe as being lost/finding myself in the health care system. This paradox became the overarching pattern of experience that subsumed several dynamic, overlapping practices described in the patterns: (1) seeking relief as suffering; (2) being classified as an addict but not an addict; (3) living with pain as remembering; and (4) experiencing treatment modalities as fickle possibilities. Explication of and interpretive commentary on these patterns shift the focus from drug seeking to pain relief seeking behaviors in chronic pain sufferers. Such a shift could change the manner in which providers work with chronic pain sufferers to find appropriate treatment modalities. Copyright © 2018 American Society for Pain Management Nursing.

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.

2015-01-01

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

It was the aim of this placebo-controlled study to evaluate the analgesic efficacy of the NASAID carprofen and the pure m-agonist levomthadone over a five-day postoperative evaluation period in dogs with fractures of the humerus or the femur (n = 30). Pain and sedation evaluation was carried out with a visual analogues system (VAS) and with the aid of a numerical estimation scale(NRS). The degree of lameness, the pain treshhold, the glucose and cortisol concentration curves as well as the respiration and heart rate and the systolic blood pressure were used as further pain indicators and to identify drug side effects. The levomethadon group displayed the lowest degree of pain on postoperative examination on the first day. On days 2 to 5, the carprofen group showed the lowest degree of pain in comparison to the placebo group. The levomethadon- and the carprofen group showed no statistically proven differences from day 2 on. Due to great variations in the pain scores and comparatively high median pain score especially on the first day of this study, the efficacy of all analgesics evaluated here must be regarded as insufficient in many cases. Only the parameter nociceptive pain treshhold showed a little, the degree of lameness, the glucose and cortisol levels showed no close correlation to the VAS and NRS pain scores and were therefore of little usefulness as postoperative pain indicators. No relevant clinical side effects caused by the used analgesics were detected in the kidney, the liver, the gastrointestinal tract and the circulatory system in this study. Rather, traumatically induced elevation of enzyme levels improves or normalised until the 5th day of the study. In addition, no negative effect on wound healing was noted, especially for carprofen. Therefore, the evaluated analgesics seems to be adequate for postoperative pain therapy also in fracture patients (trauma patients). However, the efficacy of all analgesics evaluated here must be regarded as

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

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.

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

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

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.

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.

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.

Background Almost five decades ago, governments around the world adopted the 1961 Single Convention on Narcotic Drugs which, in addition to addressing the control of illicit narcotics, obligated countries to work towards universal access to the narcotic drugs necessary to alleviate pain and suffering. Yet, despite the existence of inexpensive and effective pain relief medicines, tens of millions of people around the world continue to suffer from moderate to severe pain each year without treatment. Discussion Significant barriers to effective pain treatment include: the failure of many governments to put in place functioning drug supply systems; the failure to enact policies on pain treatment and palliative care; poor training of healthcare workers; the existence of unnecessarily restrictive drug control regulations and practices; fear among healthcare workers of legal sanctions for legitimate medical practice; and the inflated cost of pain treatment. These barriers can be understood not only as a failure to provide essential medicines and relieve suffering but also as human rights abuses. Summary According to international human rights law, countries have to provide pain treatment medications as part of their core obligations under the right to health; failure to take reasonable steps to ensure that people who suffer pain have access to adequate pain treatment may result in the violation of the obligation to protect against cruel, inhuman and degrading treatment.

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®.

S-flurbiprofen plaster (SFPP) is a novel non-steroidal anti-inflammatory drug (NSAID) patch, intended for topical treatment for musculoskeletal diseases. This trial was conducted to examine the effectiveness of SFPP using active comparator, flurbiprofen (FP) patch, on knee osteoarthritis (OA) symptoms. This was a phase III, multi-center, randomized, adequate, and well-controlled trial, both investigators and patients were blinded to the assigned treatment. Enrolled 633 knee OA patients were treated with either SFPP or FP patch for two weeks. The primary endpoint was improvement in knee pain on rising from the chair as assessed by visual analogue scale (rVAS). Safety was evaluated through adverse events (AEs). The change in rVAS was 40.9 mm in SFPP group and 30.6 mm in FP patch group (p < 0.001). The incidence of drug-related AEs at the application site was 9.5% (32 AEs, 29 mild and 3 moderate) in SFPP and 1.6% in FP patch (p < 0.001). Withdrawals due to AE were five in SFPP and one in FP patch. The superiority of SFPP in efficacy was demonstrated. Most of AEs were mild and few AEs led to treatment discontinuation. Therefore, SFPP provides an additional option for knee OA therapy.

Paediatric cancer patients often experience fear and pain from the disease but also in connection with the necessary diagnostic and therapeutic procedures. The treatment of pain is a priority for all patients, especially for critically ill children because of their vulnerability and limited understanding. The experience of pain is always subjective and depends on the age, the pain experience and the environment.In contrast to adults, it is often difficult to detect character of pain, pain intensity and pain localization in very young patients. Diagnostic and therapeutic procedures are performed in analgosedation for a given drug scheme by a pediatrician experienced in intensive care.In addition, a local anesthetic for an access system/lumbar punctures in the form of EMLA® patch is to be carried out. A rapid and effective treatment of pain and appropriate analgesia can prevent patients from being traumatized.For severe pain, malignancy- or chemotherapy-induced (eg. mucositis WHO grade 3 and 4) initial use of strong opiates is recommended instead of climbing the WHO ladder. For strong opiates, there is no maximum dose, as long as a dose increase leads to clinically observable increase in analgesia, without severe side effects. Patient-controlled analgesia with morphine as continuous subcutaneous or intravenous infusions and the possibility of a bolus injection is suited for children aged 6 years. A measurement of O2-saturation is essential during this infusion. Prophylactic approaches also must be used consistently in regard to the acute side effect of opiate treatment. Good experience, we have also made a non-drug therapy, e.g. personnel/physical affection, cuddling, massage, etc.The choice of analgesia depends on the nature and cause of pain. In neuropathic pain or phantom pain coanalgetics should be used to effectively treat pain in young patients. Different analgesic treatment approaches of the appropriate indications and adverse effects are presented. A

The aim of the study was to examine the effectiveness of a pain management program (PMP) in enhancing the knowledge and attitudes of health care workers in pain management. Many nursing home residents suffer from pain, and treatment of pain is often inadequate. Failure of health care workers to assess pain and their insufficient knowledge of pain management are barriers to adequate treatment. It was a quasiexperimental pretest and posttest study. Four nursing homes were approached, and 88 staff joined the 8-week PMP. Demographics and the knowledge and attitudes regarding pain were collected with the use of the Nurse's Knowledge and Attitudes Survey Regarding Pain-Chinese version (NKASRP-C) before and after the PMP. A deficit in knowledge and attitudes related to pain management was prominent before the PMP, and there was a significant increase in pain knowledge and attitudes from 7.9 ± SD 3.52 to 19.2 ± SD4.4 (p < .05) after the 8-week PMP. A PMP can improve the knowledge and attitudes of nursing staff and enable them to provide adequate and appropriate care to older persons in pain. PMPs for nurses and all health care professionals are important in enhancing care for older adults and to inform policy on the provision of pain management.

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.

Chronic pancreatitis is an inflammatory disease of the pancreas with abdominal pain as the most prominent symptom. Adequate treatment of patients with chronic pancreatitis remains a major challenge, mainly because of the lack of evidence-based treatment protocols. The primary goal of treatment is to achieve long-term pain relief, control of the complications associated with the disease, and to restore the quality of life. Currently, a conservative step-up approach is often used for the treatment of pain; progression to severe and intractable pain is considered necessary before invasive treatment is considered. Recent studies, however, suggest that surgical intervention should not be considered only as last-resort treatment, since it can mitigate disease progression, achieve excellent pain control, and preserve pancreatic function. In this review, we present a state-of-the art overview of endoscopic and surgical treatment options for patients with painful chronic pancreatitis, and elaborate on the timing of surgery.

In recent decades, the focus of pain management in hospitals was the organization and quality of control of postoperative pain, although there is a similar demand in nonsurgical departments. The aim of this study was to assess the employees' perspective on problems and corresponding solutions in pain management in a university hospital and to further clarify whether the implementation of concepts and tools of pain management across disciplines is feasible. Physicians and nursing staff of all inpatient departments of the University Hospital Göttingen were asked about problems in pain management and the importance of various established instruments using a standardized questionnaire. Ratings were recorded on a numeric rating scale (0-10). The analysis was primarily descriptive, the Kruskal-Wallis and Mann-Whitney U test were used when appropriate. In all, 149 medical and 501 nursing employees were included. The quality of pain management was perceived as better in surgical departments than in the conservative and pediatric departments. In all areas, the lack of an adequate order for baseline- and rescue-analgesic, and accordingly the nursing staff's limited ability to act was rated as problematic. In contrast to the conservative and pediatric departments, the predominant problem of surgical departments was the lack of availability of physicians on the ward. As a solution, the advice provided by pain consultation services was rated highly by the staff in all areas. The importance of implementation of standardized analgesic concepts was also supported equally in all areas. The evaluation of the quality of pain management was related to the employee's estimation of their ability to actively treat pain. Physicians rated problems in quality and organization lower compared to nursing stuff. The results demonstrate that from the employee's perspective problems in pain management in surgical and nonsurgical departments are very similar. Transferring concepts and structures

the numbers available, we detected no clinically important difference in pain scores throughout the hospital stay; however, patients treated with liposomal bupivacaine consumed very slightly less narcotics overall (96 ± 62 versus 84 ± 73 eq mg of morphine; [95% confidence interval, 11-13 mg]; p = 0.004) through postoperative Day 2 of inpatient hospitalization. Seventy-seven percent (406 of 527) of patients receiving liposomal bupivacaine achieved their gait milestones of clearing 100 feet of ambulation versus 60% (349 of 583) of patients receiving FNB (p < 0.001) before discharge. Likewise, 94% (497 of 527) of patients receiving liposomal bupivacaine completed stairs compared with 73% (427 of 583) of patients receiving FNB (p < 0.001). Patients who received liposomal bupivacaine were less likely to experience a fall during the hospital stay than were patients treated with FNB (3 of 527 [0.6%] versus 12 of 583 [2%]; p = 0.03). In the absence of strong data supporting FNB over liposomal bupivacaine, we have modified our TKA pain management protocols by adopting liposomal bupivacaine in lieu of FNBs, facilitating rapid rehabilitation while providing adequate pain control.

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

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.

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.

Despite the benefits that nonpharmacologic methods of pain management have to offer, nurses cite barriers that inhibit their use in practice. The purpose of this research study was to compare the perceptions of prelicensed student nurses (SNs) and registered nurses (RNs) toward nonpharmacologic methods of pain management. A sample size of 64 students and 49 RNs was recruited. Each participant completed a questionnaire about their use and perceptions nonpharmacologic pain control methods. Sixty-nine percent of RNs reported a stronger belief that nonpharmacologic methods gave relief to their patients compared with 59% of SNs (p = .028). Seventy-five percent of student nurses felt they had adequate education about nonpharmacologic pain modalities compared with 51% of RN who felt less than adequately educated (p = .016). These findings highlight the need for education about nonpharmacologic approaches to pain management. Applications of these findings may decrease barriers to the use of nonpharmacologic methods of pain management. Copyright © 2015 American Society for Pain Management Nursing.

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 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.

We compared the rate of mental health disorders in male and female patients with pelvic pain and control subjects. Male patients with chronic prostatitis/chronic pelvic pain syndrome (174) and female patients with interstitial cystitis/painful bladder syndrome (111) were identified from a urology tertiary care clinic population. A control group consisting of 72 men and 175 women was also recruited. Subjects completed self-administered questionnaires that included items about demographics, medical history, medication use and urological symptoms. The Patient Health Questionnaire was used to identify depression and panic disorder. Multiple logistic regression was used to determine odds ratios for the presence of a mental health diagnosis. Mental health disorders were identified in 13% of the chronic prostatitis/chronic pelvic pain syndrome cases and 4% of male controls (OR 2.0, p = 0.04), as well as in 23% of interstitial cystitis/painful bladder syndrome cases and 3% of female controls (OR 8.2, p <0.0001). Disease status (case vs control) (OR 10.4, p = 0.001) and income greater than $50,000 (OR 0.34, p = 0.008) were the only 2 variables independently predictive of the presence of a mental health diagnosis. Age, gender, race/ethnicity and education were not predictive. Medications for anxiety, depression or stress were being taken by 18% of patients with chronic prostatitis/chronic pelvic pain syndrome, 37% of those with interstitial cystitis/painful bladder syndrome, 7% of male controls and 13% of female controls. Depression and panic disorder are significantly more common in men and women with pelvic pain conditions than in controls. Medication use data suggest that anxiety and depression may be more difficult to treat in patients with urological pain syndromes than in controls.

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

The control of chronic pain is a major challenge for patients and health care professionals. To culturally adapt the Nursing Outcomes Classification outcome "Pain control" (PC) to the Spanish health care setting and to analyze its psychometric properties and sensitivity to change. A study of three stages was designed: (1) Translation and cultural adaptation by translation-back-translation method, (2) content validation by a group of experts, and (3) observational-longitudinal study in patients with chronic pain. Patient sampling was nonprobabilistic, and participants completed forms and questionnaires and responded to a question on pain. Statistical analysis included descriptive analysis, content validity index (for global PC and each indicator), principal component analysis, Spearman's test, Cronbach's α, Cohen's κ coefficient, and Wilcoxon range test. The new Spanish version of "Pain control" was semantically equivalent to the original, with a mean content validity index of 0.96. The clinical study included 88 patients with long-term pain, and the mean (standard deviation) interval between assessments (baseline and final) was 29.33 (8.05) days. Thirteen indicators were organized into two components. There was divergent but not convergent validity with the Change Pain Scale and Brief Pain Inventory. Between-observer agreement was κ = 0.48 and internal consistency was α = 0.85. No differences were found between mean baseline and final scores. The Spanish version of "Pain control," culturally adapted and structured in two components (13 indicators), is useful to assess and monitor pain control in patients with chronic pain.

Pain and motor control: From the laboratory to rehabilitation.

PubMed

Hodges, Paul W

2011-04-01

Movement is changed in pain and is the target of clinical interventions. Yet the understanding of the physiological basis for movement adaptation in pain remains limited. Contemporary theories are relatively simplistic and fall short of providing an explanation for the variety of permutations of changes in movement control identified in clinical and experimental contexts. The link between current theories and rehabilitation is weak at best. New theories are required that both account for the breadth of changes in motor control in pain and provide direction for development and refinement of clinical interventions. This paper describes an expanded theory of the motor adaptation to pain to address these two issues. The new theory, based on clinical and experimental data argues that: activity is redistributed within and between muscles rather than stereotypical inhibition or excitation of muscles; modifies the mechanical behaviour in a variable manner with the objective to "protect" the tissues from further pain or injury, or threatened pain or injury; involves changes at multiple levels of the motor system that may be complementary, additive or competitive; and has short-term benefit, but with potential long-term consequences due to factors such as increased load, decreased movement, and decreased variability. This expanded theory provides guidance for rehabilitation directed at alleviating a mechanical contribution to the recurrence and persistence of pain that must be balanced with other aspects of a multifaceted intervention that includes management of psychosocial aspects of the pain experience.

Postoperative pain after total knee arthroplasty remains one of the most important challenges facing patients undergoing this surgery. Providing a balance of adequate analgesia while limiting the functional impact of regional anesthesia and minimizing opioid side effects is critical to minimize adverse events and improve patient satisfaction. We asked whether bupivacaine delivered through an elastomeric device decreases the (1) patients' perception of pain after TKA; (2) narcotic consumption; and (3) narcotic-related side effects as compared with a placebo. In this prospective, double-blind, placebo-controlled study, all patients received standardized regional anesthesia, a preemptive and multimodal analgesic protocol, and a continuous intraarticular infusion at 5 mL/hour through an elastomeric infusion pump. The patients were randomized to receive either an infusion pump filled with (1) 300 mL of 0.5% bupivacaine, the experimental group (n = 75); or (2) 300 mL of 0.9% normal saline solution, the control group (n = 75). Data concerning postoperative pain levels through a visual analog scale, postoperative opioid consumption, opioid-related side effects, and complications were collected and analyzed. Patients in the experimental group receiving the bupivacaine reported a reduction in pain levels in highest, lowest, and current visual analog scale scores compared with the placebo group on the first postoperative day and highest visual analog scale score on postoperative Day 2 along with a 33% reduction in opioid consumption on postoperative Day 2 and a 54% reduction on postoperative Day 3. In patients undergoing TKA, continuous intraarticular analgesia provided an effective adjunct for pain relief in the immediate postoperative period without the disadvantages encountered with other analgesic methods.

Alterations of the neuromuscular control of the lumbar spine have been reported in patients with chronic low back pain (LBP). During trunk flexion and extension tasks, the reduced myoelectric activity of the low back extensor musculature observed during full trunk flexion is typically absent in patients with chronic LBP. To determine whether pain expectations could modulate neuromuscular responses to experimental LBP to a higher extent in patients with chronic LBP compared with controls. A cross-sectional, case-control study. Twenty-two patients with nonspecific chronic LBP and 22 age- and sex-matched control participants. Trunk flexion-extension tasks were performed under three experimental conditions: innocuous heat, noxious stimulation with low pain expectation, and noxious stimulation with high pain expectation. Noxious stimulations were delivered using a contact heat thermode applied on the skin of the lumbar region (L4-L5), whereas low or high pain expectations were induced by verbal and visual instructions. Surface electromyography of erector spinae at L2-L3 and L4-L5, as well as lumbopelvic kinematic variables were collected during the tasks. Pain was evaluated using a numerical rating scale. Pain catastrophizing, disability, anxiety, and fear-avoidance beliefs were measured using validated questionnaires. Two-way mixed analysis of variance revealed that pain was significantly different among the three experimental conditions (F2,84=317.5; p<.001). Increased myoelectric activity of the low back extensor musculature during full trunk flexion was observed in the high compared with low pain expectations condition at the L2-L3 level (F2,84=9.5; p<.001) and at the L4-L5 level (F2,84=3.7; p=.030). At the L4-L5 level, this effect was significantly more pronounced for the control participants compared with patients with chronic LBP (F2,84=3.4; p=.045). Pearson correlation analysis revealed that increased lumbar muscle activity in full flexion induced by

Knowledge and attitudes of pain management among nursing faculty.

A descriptive correlational design was used in this study to examine nursing faculty knowledge and attitudes in pain management. Relationships between age, education level, pain management preparation, length of time practicing as a nurse, length of time teaching nursing, time teaching pain management in the classroom, taught pain guidelines in the classroom, and additional continuing education about pain management were explored. Ninety-six nursing faculty participated from 16 schools of nursing in one Midwestern U.S. region. Findings identified that most of the nursing faculty recalled being taught about pain management in their basic education, but less than one-half felt adequately prepared. Most respondents said that they taught pain management, yet fewer than one-half identified that they used specific pain management guidelines. Faculty demonstrated adequate knowledge of pain assessment, spiritual/cultural issues, and pathophysiology. Areas of weakness were found in medications, interventions, and addiction. Faculty that reported teaching pain management in the classroom and reported more continuing education missed fewer items. Older nursing faculty reported more years of practice, more years of teaching, and more continuing education in pain management than younger faculty. Younger nursing faculty remembered being taught pain management in nursing school and felt more adequately prepared than older nursing faculty. Faculty that reported practicing for longer periods of time felt less prepared in pain management than faculty who practiced for shorter periods of time. More continuing education in pain management may be needed for older nurses to meet the recommendations of the Institute of Medicines' report on relieving pain in the U.S. Copyright © 2013 American Society for Pain Management Nursing.

[Functional restoration--it depends on an adequate mixture of treatment].

PubMed

Pfingsten, M

2001-12-01

In the last 50 years conventional treatments have not been able to slow down the expanding chronic low back pain problem. However, nowadays health care has changed according to a broad biopsychosocial model of health, the positive effect of activity on health and healing, emphasis on function rather than pain or impairment, and reliance upon clinical evidence. In search for new solutions "functional restoration" (FR) programs have been developed. They include multidisciplinary treatment of patients in groups, consisting of 6-8 h of treatment a day, lasting 3 to 6 weeks and usually integrating intense physical and ergonomic training, psychological (behavioral) therapy, patient education, and instruction in social- and work-related issues. FR programs have yet to demonstrate their effectiveness in several countries. Controlled studies in the USA were very positive regarding the return-to-work rate, whereas studies in Scandinavian countries did not demonstrate similar results. Possible reasons for the different results concerning back-to-work ratios might be that study design, patient population, content of the program, and other external factors are different and studies as well as effects are therefore not directly comparable. According to several well-controlled studies, the most probable reason for this different effect may be that social and security (health care) systems and cultures differ among countries and that patients with chronic low back pain respond differently to this combination. Sick absenteeism and inability to work may be influenced by many factors besides pain that cannot be addressed by intervention or prevention programs, e.g., job satisfaction, education level, and the compensation systems. It may be that the lower economic benefit during sick leave in the United States leads to favorable results from functional restoration programs. Concerning the prediction of success, several studies have shown that medical background, diagnosis and physical

The control of tonic pain by active relief learning

2018-01-01

Tonic pain after injury characterises a behavioural state that prioritises recovery. Although generally suppressing cognition and attention, tonic pain needs to allow effective relief learning to reduce the cause of the pain. Here, we describe a central learning circuit that supports learning of relief and concurrently suppresses the level of ongoing pain. We used computational modelling of behavioural, physiological and neuroimaging data in two experiments in which subjects learned to terminate tonic pain in static and dynamic escape-learning paradigms. In both studies, we show that active relief-seeking involves a reinforcement learning process manifest by error signals observed in the dorsal putamen. Critically, this system uses an uncertainty (‘associability’) signal detected in pregenual anterior cingulate cortex that both controls the relief learning rate, and endogenously and parametrically modulates the level of tonic pain. The results define a self-organising learning circuit that reduces ongoing pain when learning about potential relief. PMID:29482716

This paper summarizes the results of 100 New Zealand health care chaplains with regard to their involvement in issues concerning pain control within the New Zealand health care context. Both quantitative (via survey) and qualitative methods (in-depth interviewing) were utilized. The findings of this study indicated that approximately 52 % of surveyed hospital chaplains had provided some form of pastoral intervention directly to patients and/or their families dealing with issues concerning pain and that approximately 30 % of hospital chaplains had assisted clinical staff with issues concerning pain. NZ chaplaincy personnel involved in pain-related issues utilized a number of pastoral interventions to assist patients, their families and clinical staff. Differences of involvement between professionally stipended hospital chaplains and their volunteer chaplaincy assistants are noted, as are the perspectives of interviewed chaplains about their pastoral interventions with issues relating to pain. Some implications of this study with respect to chaplaincy utility, training and collaboration with clinical staff are noted, as are comparisons with international findings.

GP pain management: what are the 'Ps' and 'As' of pain management?

2014-08-01

Pain is one common reason for clinical encounters in primary care. The complex nature of chronic pain syndromes can make assessment and management daunting at times. This article presents an easy scheme to help general practitioners efficiently assess, manage and review/follow up patients with chronic pain. The mnemonic presented for assessment is the '4Ps' (pain, other pathology/past medical history, performance/function and psychological/psychiatric status). For management, we can also use '4Ps' (physical, psychological, pharmacological and procedural) and for review there are the '6As' (activities, analgesia, adverse effects, aberrance behaviours, affects and adequate documentation).

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.

Case-control study conducted between February 1st, 2014 and June 30th, 2015. ages 10 to 20 years, both sexes, consultation for pain (cases), or a checkup and/or school physical (controls). χ 2 test and Student" s tests were used. Odds ratios (OR) were calculated. A binary logistic regression model was constructed to independently assess each pain-related variable. A total of 4224 medical records were evaluated; 237 cases and 468 controls were included. Adolescents with pain exhibited: greater age (p < 0.0001; OR 2.3; 95% CI: 1.63.2); greater number of females (p < 0.0001; OR 2.24; 95% CI: 1.61-3.12); greater pubertal development (p < 0.0035; OR 2.16; 95% CI: 1.33.6); greater school dropout level (p < 0.0001; OR 13.4; 95% CI: 3.9-42.9); greater employment levels (p < 0.0001; OR 3.04; 95% CI: 1.7-5.3). Only age, female sex and school dropout were independently associated with consultation for pain. There were no significant differences with obesity and family structure. Older age, female sex and school dropout were independent risk factors in consultation for pain in adolescents. Puberty and employment were associated, but were not found to be independent risk factors. Sociedad Argentina de Pediatría.

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.

To determine if Mycoplasma genitalium, Ureaplasma urealyticum, and Ureaplasma parvum are more common in premenopausal women with urethral pain syndrome than in asymptomatic controls. We used a case-control study design to compare the prevalence of M. genitalium, U. urealyticum, and U. parvum using polymerase chain reaction (PCR) analysis in urine. Urethral pain syndrome was defined as localized urethral pain with or without accompanying lower urinary tract symptoms during the past month or longer and at least one negative urine culture. Among the 28 cases, 46% carried Ureaplasma species compared with 64% of the 92 controls overall (P = 0.09). There were no significant differences in the prevalence of U. parvum and U. urealyticum among controls than in patients with urethral pain syndrome (P = 0.35 and P = 0.33, respectively). Co-colonization with U. parvum and urealyticum was infrequent, and there was only one case of M. genitalium colonization, which occurred among the controls. The symptomatic profile of Ureaplasma carriers with urethral pain syndrome was heterogeneous with no clear pattern and did not differ significantly compared with patients negative for Ureaplasma. We found no evidence to support the notion that M. genitalium, U. parvum, and U. urealyticum are more prevalent in women with urethral pain syndrome than in women without lower urinary tract symptoms.

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 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.

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

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

Tactile acuity and lumbopelvic motor control in patients with back pain and healthy controls.

PubMed

Luomajoki, H; Moseley, G L

2011-04-01

Voluntary lumbopelvic control is compromised in patients with back pain. Loss of proprioceptive acuity is one contributor to decreased control. Several reasons for decreased proprioceptive acuity have been proposed, but the integrity of cortical body maps has been overlooked. We investigated whether tactile acuity, a clear clinical signature of primary sensory cortex organisation, relates to lumbopelvic control in people with back pain. Forty-five patients with back pain and 45 age- and sex-matched healthy controls participated in this cross-sectional study. Tactile acuity at the back was assessed using two-point discrimination (TPD) threshold in vertical and horizontal directions. Voluntary motor control was assessed using an established battery of clinical tests. Patients performed worse on the voluntary lumbopelvic tasks than healthy controls did (p<0.001). TPD threshold was larger in patients (mean (SD)=61 (13) mm) than in healthy controls (44 (10) mm). Moreover, larger TPD threshold was positively related to worse performance on the voluntary lumbopelvic tasks (Pearson's r=0.49; p<0.001). Tactile acuity, a clear clinical signature of primary sensory cortex organisation, relates to voluntary lumbopelvic control. This relationship raises the possibility that the former contributes to the latter, in which case training tactile acuity may aid recovery and assist in achieving normal motor performance after back injury.

To compare pain control at various time points during first-trimester surgical abortion using a patient-administered lidocaine gel compared with a traditional lidocaine paracervical block. We conducted a randomized controlled trial of women undergoing surgical abortion at less than 12 weeks of gestation in an outpatient setting. The primary outcome was pain at cervical dilation as measured on a 100-mm visual analog scale. A sample size of 142 participants was planned to detect a 15-mm or greater difference on the 100-mm visual analog scale with 90% power and a significance level of .025, adding 10% for participant dropout and protocol violations. Participants received either 12 mL of a 1% lidocaine paracervical block or 20 mL of a self-administered, 2% lidocaine gel 20-30 minutes before procedure initiation. Secondary outcomes included anticipated pain, baseline pain, pain with speculum and tenaculum placement, pain after suction aspiration, and pain 30-45 minutes postoperatively. From April to October 2015, a total of 142 women were enrolled (68 in the paracervical block group, 69 in the gel group, and five not analyzed as a result of participant withdrawal). Sociodemographic characteristics were similar between groups. The mean pain score with cervical dilation was 60 mm (95% confidence interval [CI] 54-66) in the paracervical block group and 64 mm (95% CI 59-69) in the gel group (P=.3). There was no significant difference between mean pain scores at any time points measured. Self-administration of lidocaine gel before first-trimester surgical abortion is noninferior to a traditional paracervical lidocaine block and should be considered as an alternative, noninvasive approach to pain control for first-trimester surgical abortion.

Groß, Martina; Warschburger, Petra

2013-09-01

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.

Chronic pain coping styles in patients with herniated lumbar discs and coexisting spondylotic changes treated surgically: Considering clinical pain characteristics, degenerative changes, disability, mood disturbances, and beliefs about pain control.

Pain catastrophizing, appraisals of pain control, styles of coping, and social support have been suggested to affect functioning in patients with low back pain. We investigated the relation of chronic pain coping strategies to psychological variables and clinical data, in patients treated surgically due to lumbar disc herniation and coexisting spondylotic changes. The average age of study participants (n=90) was 43.47 years (SD 10.21). Patients completed the Polish versions of the Chronic Pain Coping Inventory-42 (PL-CPCI-42), Beck Depression Inventory (BDI-PL), Coping Strategies Questionnaire (CSQ-PL), Beliefs about Pain Control Questionnaire (BPCQ-PL), and Roland-Morris Disability Questionnaire (RMQ-PL). In the PL-CPCI-42 results, resting, guarding and coping self-statements were frequently used as coping strategies (3.96 SD 1.97; 3.72 SD 1.72; 3.47 SD 2.02, respectively). In the CSQ-PL domains, catastrophizing and praying/hoping were frequently used as coping strategies (3.62 SD 1.19). The mean score obtained from the BDI-PL was 11.86 SD 7.23, and 12.70 SD 5.49 from the RMDQ-PL. BPCQ-PL results indicate that the highest score was in the subscale measuring beliefs that powerful others can control pain (4.36 SD 0.97). Exercise correlated significantly with beliefs about internal control of pain (rs=0.22). We identified associations between radiating pain and guarding (p=0.038) and between sports recreation and guarding (p=0.013) and task persistence (p=0.041). Back pain characteristics, depressive mood, disability, and beliefs about personal control of pain are related to chronic LBP coping styles. Most of the variables related to advancement of degenerative changes were not associated with coping efforts.

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

To evaluate the psychometric properties of the Multidimensional Pain Inventory (MPI) in a Brazilian sample of patients with orofacial pain. A total of 1,925 adult patients, who sought dental care in the School of Dentistry of São Paulo State University's Araraquara campus, were invited to participate; 62.5% (n=1,203) agreed to participate. Of these, 436 presented with orofacial pain and were included. The mean age was 39.9 (SD=13.6) years and 74.5% were female. Confirmatory factor analysis was conducted using χ²/df, comparative fit index, goodness of fit index, and root mean square error of approximation as indices of goodness of fit. Convergent validity was estimated by the average variance extracted and composite reliability, and internal consistency by Cronbach's alpha standardized coefficient (α). The stability of the models was tested in independent samples (test and validation; dental pain and orofacial pain). The factorial invariance was estimated by multigroup analysis (Δχ²). Factorial, convergent validity, and internal consistency were adequate in all three parts of the MPI. To achieve this adequate fit for Part 1, item 15 needed to be deleted (λ=0.13). Discriminant validity was compromised between the factors "activities outside the home" and "social activities" of Part 3 of the MPI in the total sample, validation sample, and in patients with dental pain and with orofacial pain. A strong invariance between different subsamples from the three parts of the MPI was detected. The MPI produced valid, reliable, and stable data for pain assessment among Brazilian patients with orofacial pain.

Dizziness, Unsteadiness, Visual Disturbances, and Sensorimotor Control in Traumatic Neck Pain.

Treleaven, Julia

2017-07-01

Synopsis There is considerable evidence to support the importance of cervical afferent dysfunction in the development of dizziness, unsteadiness, visual disturbances, altered balance, and altered eye and head movement control following neck trauma, especially in those with persistent symptoms. However, there are other possible causes for these symptoms, and secondary adaptive changes should also be considered in differential diagnosis. Understanding the nature of these symptoms and differential diagnosis of their potential origin is important for rehabilitation. In addition to symptoms, the evaluation of potential impairments (altered cervical joint position and movement sense, static and dynamic balance, and ocular mobility and coordination) should become an essential part of the routine assessment of those with traumatic neck pain, including those with concomitant injuries such as concussion and vestibular or visual pathology or deficits. Once adequately assessed, appropriate tailored management should be implemented. Research to further assist differential diagnosis and to understand the most important contributing factors associated with abnormal cervical afferent input and subsequent disturbances to the sensorimotor control system, as well as the most efficacious management of such symptoms and impairments, is important for the future.

To determine if the use of hydrocortisone cream decreases perineal pain in the immediate postpartum period. This was a randomized controlled trial (RCT), crossover study design, with each participant serving as their own control. Participants received three different methods for perineal pain management at three sequential perineal pain treatments after birth: two topical creams (corticosteroid; placebo) and a control treatment (no cream application). Treatment order was randomly assigned, with participants and investigators blinded to cream type. The primary dependent variable was the change in perineal pain levels (posttest minus pretest pain levels) immediately before and 30 to 60 minutes after perineal pain treatments. Data were analyzed with analysis of variance, with p < 0.05 considered significant. A total of 27 participants completed all three perineal pain treatments over a 12-hour period. A reduction in pain was found after application of both the topical creams, with average perineal pain change scores of -4.8 ± 8.4 mm after treatment with hydrocortisone cream (N = 27) and -6.7 ± 13.0 mm after treatment with the placebo cream (N = 27). Changes in pain scores with no cream application were 1.2 ± 10.5 mm (N = 27). Analysis of variance found a significant difference between treatment groups (F2,89 = 3.6, p = 0.03), with both cream treatments having significantly better pain reduction than the control, no cream treatment (hydrocortisone vs. no cream, p = 0.04; placebo cream vs. no cream, p = 0.01). There were no differences in perineal pain reduction between the two cream treatments (p = .54). This RCT found that the application of either hydrocortisone cream or placebo cream provided significantly better pain relief than no cream application.

(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.

Demonstration of improved postoperative pain management by implementation of the S3 guidelines on treatment of acute perioperative and posttraumatic pain, by the integrated quality management concept "quality management acute pain" of the TÜV Rheinland or by participation in the benchmark project "Quality improvement in postoperative pain management" (QUIPS). A prospective controlled study (pre-post design) was carried out in hospitals with various levels of care comparing three hospital groups (n = 17/7/3, respectively). Group 1: participation in the QUIPS project (intraclinic and interclinic comparison of outcome data of postoperative pain treatment), group 2: participation in the quality management acute pain program (certified by TÜV Rheinland), group 3: control group with no involvement in either of the two concepts. In all three groups, an anonymous data collection was performed consisting of patient-reported pain intensity, side effects, pain disability and patient satisfaction. Pain therapy intervention was carried out only in group 2 by an integrated quality management concept (certification project: Quality management acute pain) with a package of measures to improve structure, process and outcome quality. The TÜV Rheinland certified clinics (group 2) showed a significant improvement in the pre-post comparison (before versus after certification) in the areas maximum pain (from visual analogue scale VAS 4.6 to 3.7), stress pain (5.3 to 3.9), pain-related impairment (proportion of patients with pain-linked decreased mobility and movement 26% to 16.1%, coughing and breathing 23.1% to 14.3%) and patient satisfaction (from 13.2 to 13.7; scale 0 completely unsatisfied, 15 very satisfied). The clinics with participation in QUIPS for 2 years also showed a significant improvement in stress pain (numeric rating scale NRS for pain 4.5 to 4.2), pain-linked-limitation of coughing and breathing (28% to 23.6%), and patient satisfaction (from 11.9 to 12.4).

The significance of occlusal disharmony for the development of painful temporomandibular disorder (TMD) is controversial. The ongoing biomechanical strain caused by occlusal disharmony might lead to sensitization processes in the nociceptive system. Understanding these processes might be an important step toward understanding the possible relationship between occlusal disharmony and TMD. In this study, we therefore investigated whether subjects with occlusal disharmony (n = 22) differ from healthy controls (n = 26) in their pain perception and pain modulation by stress and relaxation. Trigeminal and extratrigeminal experimental pain perception (pinprick, heat, and pressure pain) was assessed before and after stress (mental arithmetic) and relaxation (viewing of low-arousal pictures). There were no group differences in pain perception at baseline or during the stress task. Compared with controls, the occlusal disharmony group exhibited an inadequate reduction in pain perception during relaxation, which was significant for the extratrigeminal site (P < 0.01) and reached a trend for significance at the trigeminal site (P = 0.1). These results suggest that subjects with occlusal disharmony show signs of disturbed endogenous pain inhibition during relaxation. There is evidence for the presence of sensitization of the nociceptive system in subjects with occlusal disharmony. Possibly, deficient inhibition of extratrigeminal and trigeminal pain perception by relaxation might contribute to the development of TMD or other chronic pain disorders. © 2014 John Wiley & Sons A/S.

Persistent knee pain in people over 50 years of age is often attributable to knee osteoarthritis (OA), a common joint condition that causes physical and psychological dysfunction. Exercise and pain coping skills training (PCST) can help reduce the impact of persistent knee pain, however, access to health professionals who deliver these services can be challenging. With increasing access to the Internet, remotely delivered Internet-based treatment approaches may provide alternatives for healthcare delivery. This pragmatic randomised controlled trial will investigate whether an Internet-delivered intervention that combines PCST and physiotherapist-guided exercise (PCST + Ex) is more effective than online educational material (educational control) in people with persistent knee pain. We will recruit 148 people over 50 years of age with self-reported persistent knee pain consistent with knee OA from the Australian community. Following completion of baseline questionnaires, participants will be randomly allocated to access a 3-month intervention of either (i) online educational material, or (ii) the same online material plus an 8-module (once per week) Internet-based PCST program and seven Internet-delivered physiotherapy sessions with a home exercise programs to be performed 3 times per week. Outcomes will be measured at baseline, 3 months and 9 months with the primary time point at 3 months. Primary outcomes are average knee pain on walking (11-point numeric rating scale) and self-reported physical function (Western Ontario and McMaster Universities Osteoarthritis Index subscale). Secondary outcomes include additional measures of knee pain, health-related quality-of-life, perceived global change in symptoms, and potential moderators and mediators of outcomes including self-efficacy for pain management and function, pain coping attempts and pain catastrophising. Other measures of adherence, adverse events, harms, use of health services/co-interventions, and process

Today, chronic low back pain is one of the special challenges in healthcare. There is no unique approach to treat chronic low back pain. A variety of methods are used for the treatment of low back pain, but the effects of these methods have not yet been investigated adequately. The aim of this study was to compare the effects of Pilates and McKenzie training on pain and general health of men with chronic low back pain. Thirty-six patients with chronic low back pain were chosen voluntarily and assigned to three groups of 12 each: McKenzie group, Pilates group, and control group. The Pilates group participated in 1-h exercise sessions, three sessions a week for 6 weeks. McKenzie group performed workouts 1 h a day for 20 days. The control group underwent no treatment. The general health of all participants was measured by the General Health Questionnaire 28 and pain by the McGill Pain Questionnaire. After therapeutic exercises, there was no significant difference between Pilates and McKenzie groups in pain relief ( P = 0.327). Neither of the two methods was superior over the other for pain relief. However, there was a significant difference in general health indexes between Pilates and McKenzie groups. Pilates and McKenzie training reduced pain in patients with chronic low back pain, but the Pilates training was more effective to improve general health.

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.

We evaluated the pharmacological treatment of distal sensorimotor polyneuropathy (DSPN) among older subjects from the general population. The study included subjects aged 61 to 82 years from the KORA F4 survey (2006-2008). DSPN was defined as the presence of bilaterally impaired foot-vibration perception and/or bilaterally impaired foot-pressure sensation. Pain intensity was assessed with the painDETECT questionnaire. From the included 1076 older persons, 172 (16%) persons reported pain in the lower extremities and DSPN was present in 150 (14%) subjects. Forty-eight people with pain in the lower extremities reported DSPN. Only 38% of the subjects with DSPN reporting an average pain level of ≥4 during the past 4 weeks received medical treatment, predominantly nonsteroidal anti-inflammatory drugs (NSAIDs 20% and opioids 12%). The medication of choice for neuropathic pain, antidepressants, anticonvulsants, and opioids was relatively being underused. However, opioids and neuropathy preparations were prescribed preferably for subjects with painful DSPN. In the older general population, only a small proportion of subjects with painful DSPN receive analgesic pharmacotherapy. Although not recommended by guidelines for the treatment of neuropathic pain, NSAIDs were the most frequently used class of analgesic drugs. Copyright © 2018 John Wiley & Sons, Ltd.

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

To evaluate the accuracy of a questionnaire modified for the identification of intraoral pain with neuropathic characteristics in a clinical orofacial pain sample population. 136 participants with at least one of four orofacial pain diagnoses (temporomandibular disorders [TMD, n = 41], acute dental pain [ADP, n = 41], trigeminal neuralgia [TN, n = 19], persistent dentoalveolar pain disorder [PDAP, n = 14]) and a group of pain-free controls (n = 21) completed the modified S-LANSS, a previously adapted version of the original questionnaire devised to detected patients suffering from intraoral pain with neuropathic characteristics. Psychometric properties (sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV]) were calculated in two analyses with two different thresholds: (1) Detection of pain with neuropathic characteristics: PDAP + TN were considered positive, and TMD + ADP + controls were considered negative per gold standard (expert opinion). (2) Detection of PDAP: PDAP was considered positive and TMD + ADP were considered negative per gold standard. For both analyses, target values for adequate sensitivity and specificity were defined as ≥ 80%. For detection of orofacial pain with neuropathic characteristics (PDAP + TN), the modified S-LANSS presented with the most optimistic threshold sensitivity of 52% (95% confidence interval [CI], 34-69), specificity of 70% (95% CI, 60-79), PPV of 35% (95% CI, 22-51), and NPV of 82% (95% CI, 72-89). For detection of PDAP only, with the most optimistic threshold sensitivity was 64% (95% CI, 35-87), specificity 63% (95% CI, 52-74), PPV 23% (95% CI, 11-39) and NPV 91% (95% CI, 81-97). Based on a priori defined criteria, the modified S-LANSS did not show adequate accuracy to detect intraoral pain with neuropathic characteristics in a clinical orofacial pain sample.

The degree and salience of pain have been known to be constantly monitored and modulated by the brain. In the case of maladaptive neural responses as reported in centralized pain conditions such as complex regional pain syndrome (CRPS), the perception of pain is amplified and remains elevated even without sustained peripheral pain inputs. Given that the attentional state of the brain greatly influences the perception and interpretation of pain, we investigated the role of the attention network and its dynamic interactions with other pain-related networks of the brain in CRPS. We examined alterations in the intra- and inter-network functional connectivities in 21 individuals with CRPS and 49 controls. CRPS-related reduction in intra-network functional connectivity was found in the attention network. Individuals with CRPS had greater inter-network connectivities between the attention and salience networks as compared with healthy controls. Furthermore, individuals within the CRPS group with high levels of pain catastrophizing showed greater inter-network connectivities between the attention and salience networks. Taken together, the current findings suggest that these altered connectivities may be potentially associated with the maladaptive pain coping as found in CRPS patients.

The plasticity of descending controls in pain: translational probing.

PubMed

Bannister, Kirsty; Dickenson, A H

2017-07-01

Descending controls, comprising pathways that originate in midbrain and brainstem regions and project onto the spinal cord, have long been recognised as key links in the multiple neural networks that interact to produce the overall pain experience. There is clear evidence from preclinical and clinical studies that both peripheral and central sensitisation play important roles in determining the level of pain perceived. Much emphasis has been put on spinal cord mechanisms in central excitability, but it is now becoming clear that spinal hyperexcitability can be regulated by descending pathways from the brain that originate from predominantly noradrenergic and serotonergic systems. One pain can inhibit another. In this respect diffuse noxious inhibitory controls (DNIC) are a unique form of endogenous descending inhibitory pathway since they can be easily evoked and quantified in animals and man. The spinal pharmacology of pathways that subserve DNIC are complicated; in the normal situation these descending controls produce a final inhibitory effect through the actions of noradrenaline at spinal α 2 -adrenoceptors, although serotonin, acting on facilitatory spinal 5-HT 3 receptors, influences the final expression of DNIC also. These descending pathways are altered in neuropathy and the effects of excess serotonin may now become inhibitory through activation of spinal 5-HT 7 receptors. Conditioned pain modulation (CPM) is the human counterpart of DNIC and requires a descending control also. Back and forward translational studies between DNIC and CPM, gauged between bench and bedside, are key for the development of analgesic therapies that exploit descending noradrenergic and serotonergic control pathways. © 2017 The Authors.

To investigate the possible effect of intraoperative analgesia, namely diclofenac sodium compared to acetaminophen on post-recovery pain perception in children undergoing painful dental procedures under general anaesthesia. A double-blind randomised clinical trial. A sample of 180 consecutive cases of children undergoing full dental rehabilitation under general anaesthesia in a private hospital in Saudi Arabia during 2013 was divided into three groups (60 children each) according to the analgesic used prior to extubation. Group A, children had diclofenac sodium suppository. Group B, children received acetaminophen suppository and Group C, the control group. Using an authenticated Arabic version of the Wong and Baker faces Pain assessment Scale, patients were asked to choose the face that suits best the pain he/she is suffering. Data were collected and recorded for statistical analysis. Student's t test was used for comparison of sample means. A preliminary F test to compare sample variances was carried out to determine the appropriate t test variant to be used. A "p" value less than 0.05 was considered significant. More than 93% of children had post-operative pain in varying degrees. High statistical significance was observed between children in groups A and B compared to control group C with the later scoring high pain perception. Diclofenac showed higher potency in multiple painful procedures, while the statistical difference was not significant in children with three or less painful dental procedures. Diclophenac sodium is more potent than acetaminophen, especially for multiple pain-provoking or traumatic procedures. A timely use of NSAID analgesia just before extubation helps provide adequate coverage during recovery. Peri-operative analgesia is to be recommended as an essential treatment adjunct for child dental rehabilitation under general anaesthesia.

To assess the effect of a pain neurophysiology education (PNE) program plus therapeutic exercise (TE) for patients with chronic low back pain (CLBP). Single-blind randomized controlled trial. Private clinic and university. Patients with CLBP for ≥6 months (N=56). Participants were randomized to receive either a TE program consisting of motor control, stretching, and aerobic exercises (n=28) or the same TE program in addition to a PNE program (n=28), conducted in two 30- to 50-minute sessions in groups of 4 to 6 participants. The primary outcome was pain intensity rated on the numerical pain rating scale which was completed immediately after treatment and at 1- and 3-month follow-up. Secondary outcome measures were pressure pain threshold, finger-to-floor distance, Roland-Morris Disability Questionnaire, Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, and Patient Global Impression of Change. At 3-month follow-up, a large change in pain intensity (numerical pain rating scale: -2.2; -2.93 to -1.28; P<.001; d=1.37) was observed for the PNE plus TE group, and a moderate effect size was observed for the secondary outcome measures. Combining PNE with TE resulted in significantly better results for participants with CLBP, with a large effect size, compared with TE alone.

Pain is among the most important symptoms in terms of prevalence and a major cause of distress for cancer patients and their family caregivers. Thus, we conducted this study with the aim to compare assessment of pain among cancer patients and their caregivers and to determine the problems experienced by caregivers. A cross-sectional and descriptive design was used. This study was conducted in a chemotherapy unit and an adult oncology clinic with 220 patients diagnosed with cancer who admitted to an oncology hospital and 220 caregivers. The study data was collected using a questionnaire and visual analogue scale (VAS, where "0: no pain," "10: severe pain"). Statistically significant levels were set at p < 0.05. Pain severity as assessed by patients and their caregivers was 7.1 ± 2.8 and 7.3 ± 2.4, respectively, and the most common pain-related problems in cancer patients were fatigue (p < 0.05), loss of appetite and insomnia (p > 0.05) as reported by both patients and caregivers. Compared to their caregivers, patients more frequently reported financial burden associated with pain management and negative effects of cancer pain on their work life and domestic life and family relationships, all of which were statistically significant (p < 0.05). The caregivers most commonly reported fatigue (56.8%) in their role as a caregiver. Pain assessments of both patients and caregivers and seeking their input on how to manage potential pain-related problems are crucial to achieve adequate pain control. In addition, psychological distress experienced by caregivers should not be overlooked.

To explore women's preferences for pain control during first-trimester surgical abortion. Pre- and postoperative semistructured individual interviews were conducted with 40 women divided into eight strata by anesthesia choice, age and prior vaginal delivery status. We identified key themes in the interviews and analyzed baseline characteristics and responses to close-ended questions within and across the strata. For most women, pain control options were not the primary concern in choosing a clinic for an abortion. Women who received intravenous (IV) sedation had lower pain scores and were more likely to report that they would recommend that method to a friend than women who received local anesthesia alone. Women described the pain as a cramping, tugging, pulling and scraping sensation. Respondents recommended IV sedation for a woman who was very anxious or could not tolerate pain, even though more nausea and vomiting may occur. Most women felt that pain control decisions should be individualized. Copyright © 2012 Elsevier Inc. All rights reserved.

Objective To determine whether an acupuncture technique specially developed for a surgical oncology population (intervention) reduces pain or analgesic use after thoracotomy compared to a sham acupuncture technique (control). Methods One hundred and sixty two cancer patients undergoing thoracotomy were randomized to group A) preoperative implantation of small intradermal needles which were retained for 4 weeks or B) preoperative placement of sham needles at the same schedule. Numerical Rating Scale (NRS) of pain and total opioid use we evaluated during the in-patient stay; Brief Pain Inventory (BPI) and Medication Quantification Scale (MQS) were evaluated after discharge up to 3 months after the surgery. Results The principal analysis, a comparison of BPI pain intensity scores at the 30 day follow-up, showed no significant difference between the intervention and control group. Pain scores were marginally higher in the intervention group 0.05 (95% C.I.: 0.74, -0.64; p=0.9). There were also no statistically significant differences between groups for secondary endpoints, including chronic pain assessments at 60 and 90 days, in-patient pain, and medication use in hospital and after discharge. Conclusion A special acupuncture technique as provided in this study did not reduce pain or use of pain medication after thoracotomy more than a sham technique. PMID:19114190

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.

The study was conducted to evaluate the effect of perioperative ketorolac on pain associated with first-trimester aspiration abortion. A double-blind, randomized, placebo-controlled trial was performed involving pregnant women up to 14 weeks' gestation who desired pregnancy termination. Subjects were randomized to receive ketorolac 30 mg intravenously (n=31) or placebo (n=45) at the time of induction of anesthesia. Postoperative pain was assessed using a visual analog scale (VAS). The primary outcome was pain control as determined by VAS score. Secondary measures of patient use of supplemental postoperative pain medications and patient satisfaction were assessed. Subjects in the ketorolac group had lower postoperative pain scores on the VAS at all time points compared to the placebo group, but the difference was not statistically significant. The ketorolac group used less postoperative acetaminophen compared to the placebo group (6.5% versus 35.6%), respectively. Subjects in the placebo group and the ketorolac group had similar requirements for postoperative narcotics in the recovery room (22.2% versus 19.4%). Patient satisfaction with pain level was equivalent between the groups at all postoperative end points. There was no observed difference in perioperative blood loss observed between the two groups. Perioperative ketorolac has the same effect on postoperative pain as determined by VAS as placebo. The use of ketorolac at the 30-mg dose cannot be recommended for better pain control for patients undergoing first-trimester pregnancy termination by suction curettage. The only positive effect of the use of ketorolac compared to placebo was a reduction in the use of acetaminophen. Ketorolac use does not appear to change blood loss in the operating room or through postoperative day 1 compared to placebo. Copyright © 2012 Elsevier Inc. All rights reserved.

Electro-acupuncture (EA) can be effective in some pain conditions, but still there have been no randomized controlled studies of EA for treatment of acute postoperative pain in nasal septoplasty. Therefore, we did a study to test whether EA of specific points is superior to sham acupuncture for complementary analgesia after nasal septoplasty. Ninety (90) patients with an American Society of Anesthesiology (ASA) physical status of I-II scheduled for elective septoplasty were randomly allocated to acupuncture group or control group. Postoperative pain was treated with intravenous meperidine. The time to the first analgesic request, and pain intensity on a 100-mm visual analogue scale (VAS-100) were used to evaluate postoperative pain, and the amount of postoperative meperidine and incidence of analgesia related to side-effects were recorded. Postoperative pain intensity on VAS-100 and respiratory depression were similar in both groups (p > 0.05), but nausea and vomiting were less in the acupuncture group than in the control group (p < 0.05). Findings from our study demonstrate that both uses of EA and 0.1 mg/kg IV morphine given intraoperatively resulted in a similar postoperative pain score, and meperidine was not given in any patient in the two groups during postoperative period because the VAS scores of all patients were less than 40 mm.

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.

2007-10-01

Although blunt trauma injury is a common cause for adolescent pain, little is known about the experience of pain as perceived by adolescents. Semistructured interviews were conducted with 13 adolescents following blunt trauma injury. Two age-appropriate valid measures (i.e., Adolescent Pediatric Pain Tool and Temporal Dot Matrix) were incorporated into the interviews to elaborate their pain experiences. Grounded theory method was used to analyze data and build substantive theory. Adolescents' behavioral and cognitive actions (i.e., "internal control") to manage and endure pain were influenced by their pain perceptions, physical losses, and clinicians' actions. Nurses, family members, and peers have a crucial role in alleviating adolescents' distress and pain.

Three hundred and twenty-two Canadian animal health technologists (AHTs) were surveyed to determine their attitudes toward postoperative pain management in dogs and cats following 6 surgical procedures, their concerns regarding the use of opioid analgesics, and their role within veterinary practices with respect to postoperative pain control. Two hundred and sixty-four (82%) returned the questionnaire. Pain perception was defined as the average of pain rankings for dogs and cats (on a scale of 1 to 10) following abdominal surgery, or the value for dogs or cats if the AHT worked with only 1 of the 2 species. Maximum concern about the risks associated with the postoperative use of morphine or oxymorphone was defined as the highest rating assigned to any of the 6 risks evaluated in either dogs or cats. Animal health technologists reported significantly higher pain perception scores than did veterinarians who completed a similar survey 2 years previously. Higher pain perception scores were associated with decreased satisfaction with the adequacy of analgesic therapy in their practice, higher pain control goals, and attendance at continuing education within the previous 12 months. The majority of AHTs (55%) agreed that one or more risks associated with the use of morphine or oxymorphone outweighed the benefits. The 3 issues that were perceived to pose the greatest risk were respiratory depression, bradycardia, and sedation and excitement, for dogs and cats, respectively. Most AHTs (68%) considered their knowledge related to the recognition and control of pain to be adequate, compared with 24% of veterinarians who responded to a similar previous survey. As for veterinarians, experience gained while in practice was ranked as the most important source of knowledge, while the technical program attended was ranked as least important. Over 88% of the AHTs provided nursing care during the postoperative period, monitored animals for side effects of postoperative analgesic

Thus Jefferson says, "The art of life is the art of avoiding pain." How can we possibly avoid pain either physical or psychological throughout our life span? Perhaps it is more realistic to do our best to minimize pain or manage it effectively. Managing pain throughout the preoperative and postoperative periods is achievable, but we are not always doing an adequate job. The focus of this article is to provide an opportunity to look at using appropriate medications, treatment approaches, and timing for the orthopaedic patient. The concepts of preemptive analgesia and around-the-clock (ATC) dosing are discussed.

Slack (Slo2.2) is a sodium-activated potassium channel that regulates neuronal firing activities and patterns. Previous studies identified Slack in sensory neurons, but its contribution to acute and chronic pain in vivo remains elusive. Here we generated global and sensory neuron-specific Slack mutant mice and analyzed their behavior in various animal models of pain. Global ablation of Slack led to increased hypersensitivity in models of neuropathic pain, whereas the behavior in models of inflammatory and acute nociceptive pain was normal. Neuropathic pain behaviors were also exaggerated after ablation of Slack selectively in sensory neurons. Notably, the Slack opener loxapine ameliorated persisting neuropathic pain behaviors. In conclusion, Slack selectively controls the sensory input in neuropathic pain states, suggesting that modulating its activity might represent a novel strategy for management of neuropathic pain.

This study evaluated the effectiveness of cold-gel packing on episiotomy pain among postpartum women who had normal spontaneous deliveries. A quasi-randomised control trial was conducted in a maternity ward of a regional teaching hospital in northern Taiwan. Seventy postpartum women were recruited, choosing to be in either the experimental or control group (35 women per group). Subjects in the experimental group received at least six interventions of cold-gel packing applied to the perineal wound and were provided oral analgesics routinely. The subjects in the control group received oral analgesics routinely. Pain intensity, pain interference on daily activities and satisfaction levels with pain management were assessed using Brief Pain Inventory (BPI) and pain management questionnaire, respectively. The results showed that women in the experimental group reported significantly lower mean pain intensity score, pain interference on daily activities scores at 48 hours post-delivery, and higher level of satisfaction with pain management at 24 and 48 hours post-delivery than the control group after adjusting for demographic and obstetric data. Cold-gel packing on the perineum is a cost-effective, convenient, easy-to-deploy and non-pharmacologic approach to pain reduction, with an overall positive impact on postpartum recovery for parturients.

Background To determine whether there is a difference between patients with low back pain and healthy controls in a test battery score for movement control of the lumbar spine. Methods This was a case control study, carried out in five outpatient physiotherapy practices in the German-speaking part of Switzerland. Twelve physiotherapists tested the ability of 210 subjects (108 patients with non-specific low back pain and 102 control subjects without back pain) to control their movements in the lumbar spine using a set of six tests. We observed the number of positive tests out of six (mean, standard deviation and 95% confidence interval of the mean). The significance of the differences between the groups was calculated with Mann-Whitney U test and p was set on <0.05. The effect size (d) between the groups was calculated and d>0.8 was considered a large difference. Results On average, patients with low back pain had 2.21(95%CI 1.94–2.48) positive tests and the healthy controls 0.75 (95%CI 0.55–0.95). The effect size was d = 1.18 (p < 0.001). There was a significant difference between acute and chronic (p < 0.01), as well as between subacute and chronic patient groups (p < 0.03), but not between acute and subacute patient groups (p > 0.7). Conclusion This is the first study demonstrating a significant difference between patients with low back pain and subjects without back pain regarding their ability to actively control the movements of the low back. The effect size between patients with low back pain and healthy controls in movement control is large. PMID:19108735

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.

Liposomal bupivacaine (LB) is a long-acting local anesthetic reported to decrease postoperative pain in adults. The authors demonstrate the safe use of LB in pediatric patients with improved pain control following palatoplasty. Retrospective patient series of all single-surgeon palatoplasty patients treated at a tertiary craniofacial center from August 2014 to December 2015 were included. All patients received 1.3% LB intraoperatively as greater palatal nerve and surgical field blocks in 2-flap V-Y pushback palatoplasty. Postoperative oral intake, opioids administered, duration of hospitalization, and FLACC (face, legs, activity, cry, consolability) pain scores were measured. Twenty-seven patients (16 males and 11 females, average age of 10.8 months, weight 8.8 kg) received 2.9 ± 0.9 mL (2.6 ± 1.9 mg/kg) 1.3% LB. Average FLACC scores were 2.4 ± 2.2/10 in the postanesthesia care unit and 3.8 ± 1.8/10 while inpatients. Oral intake was first tolerated 10.3 ± 11.5 hours postoperatively and tolerated 496.4 ± 354.2 mL orally in the first 24 hours postoperatively. Patients received 8.5 ± 8.4 mg hydrocodone equivalents (0.46 ± 0.45 mg/kg per d hydrocodone equivalents) and were discharged 2.1 ± 1.3 days postoperatively. Opioid-related adverse events included emesis in 7.4% and pruritis in 3.7% of patients. The LB may be used safely in pediatric patients. Intraoperative injection of LB during palatoplasty can yield low postoperative opioid use and an early and adequate volume of oral intake over an average hospital stay. Further cost-efficacy studies of LB are needed to assess its value in pediatric plastic surgery.

Witnessing emotional events such as arousal or pain may impair ongoing cognitive processes such as inhibitory control. We found that this may be true only half of the time. Erotic images and painful video clips were shown to men and women shortly before a stop signal task, which measures cognitive inhibitory control. These stimuli impaired inhibitory control only in men and not in women, suggesting that emotional stimuli may be processed with different weights depending on gender. Copyright © 2012 Elsevier B.V.

Electrical stimulation in the treatment of pain.

PubMed

Rushton, David N

2002-05-20

To review the published literature concerning the treatment of painful conditions using devices that deliver electrical stimulation to nervous structures. The review briefly surveys the results obtained using surface electrodes ("TENS") as well as implanted devices. The method used is a critical review of the important published literature up to mid-1999. References were obtained using Medline and the keywords "pain", together with "electrical", "stimulation", "neurostimulation" or "TENS". Electrical stimulation has been found to be of potential benefit in the management of a range of painful conditions. Adequately controlled trials of electrical stimulation are often difficult to achieve. Implanted devices tend to be used in the more severe intractable pain conditions. It is likely that there is more than one mechanism of action. The mechanisms of action are however still often poorly understood, even though historically theoretical and experimental advances in the understanding of pain mechanisms prompted the development of clinical systems and the institution of clinical studies. TENS has proved to be remarkably safe, and provides significant analgesia in about half of patients experiencing moderate predictable pain. Implanted devices can be more effective, but they carry a risk of device failure, implant infection or surgical complication, and are reserved for the more severe intractable chronic pains. The main implanted devices used clinically are the spinal cord stimulator and the deep brain stimulator.

The multiple bodily pain conditions in temporomandibular disorders (TMD) have been associated with generalized alterations in pain processing. The purpose of this study was to examine the relationship between the presence of widespread body palpation tenderness (WPT) and the likelihood of multiple comorbid pain conditions in TMD patients and controls. This case-control study was conducted in 76 TMD subjects with WPT, 83 TMD subjects without WPT, and 181 non-TMD matched control subjects. The study population was also characterized for clinical pain, experimental pain sensitivity, and related psychological phenotypes. Results showed that (1) TMD subjects reported an average of 1.7 comorbid pain conditions compared to 0.3 reported by the control subjects (p<0.001); (2) Compared to control subjects, the odds ratio (OR) for multiple comorbid pain conditions is higher for TMD subjects with WPT [OR 8.4 (95% CI 3.1–22.8) for TMD with WPT versus OR 3.3 (95% CI 1.3–8.4) for TMD without WPT]; (3) TMD subjects with WPT presented with reduced pressure pain thresholds (PPTs) in both cranial and extra-cranial regions compared to TMD subjects without WPT; and (4) TMD subjects with WPT reported increased somatic symptoms. These findings suggest that pain assessment outside of the orofacial region may prove valuable for the classification, diagnosis, and management of TMD patients. PMID:23031401

Although current research findings suggest that postural control or static balance is impaired in subjects with low back pain, few studies have specifically addressed the effect of low back pain on static balance in elite athletes. Forty-four athletes belonging to Chilean national teams took part in this study; 20 had low back pain and the remaining 24 were healthy controls. Displacement of the centre of pressure was analyzed by computerized platform posturography, using a standardized protocol; subjects were required to stand upright on both feet, with eyes first open then closed. The results showed that, athletes with low back pain used significantly more energy (p< 0.0182) and had a greater displacement of the centre of pressure (p< 0.005) with open eyes to control posture than healthy athletes. It may be concluded that static balance is impaired in elite athletes with low back pain and that analysis of two-footed stance provides a sensitive assessment of static balance in athletes.

The Effect of Foot Reflexology on Acute Pain in Infants: A Randomized Controlled Trial.

This study was a randomized controlled trial designed to evaluate the effect of foot reflexology applied on infants on acute pain that may arise after vaccine injection. The sample consisted of 1- to 12-month-old infants registered in a family health center in Istanbul, Turkey, for healthcare follow-up. A total of 60 infants who met the criteria of the sample group were included in the study; 30 infants constituted the reflexology group and the other 30 constituted the control group. Although questionnaire forms were used to determine the descriptive characteristics of infant-mother pairs, the Face, Legs, Activity, Cry, Consolability (FLACC) Pain Assessment Scale was used to evaluate pain level. Infants in the reflexology group received reflexology treatment for an average of 20-30 minutes before vaccination, depending on the physical size of the infant's foot. Pain, heart rate, oxygen saturation levels, and crying periods of infants in the reflexology and control groups were evaluated before and after vaccination. The FLACC pain score was observed to be statistically similar between groups. After reflexology was applied to infants in the reflexology group before vaccination, it was determined that the pain score was reduced to .50 ± 1.14. In the examination performed after vaccination, FLACC pain score was found to be 5.47 ± 2.11 in the reflexology group and 9.63 ± .85 in the control group. A statistically significant difference was observed between the mean FLACC pain scores of infants in the reflexology and control groups (p = .000). The infants in the reflexology group also had lower heart rates, higher oxygen saturation, and shorter crying periods than the infants in the control group (p <.001). Reflexology before vaccine reduced the pain level experienced after vaccination. Future research needs to explore different interventional practices. © 2015 Sigma Theta Tau International.

Induced sensorimotor brain plasticity controls pain in phantom limb patients

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

Introduction The practice and study of pain management pose myriad ethical challenges. There is a consensual opinion that adequate management of pain is a medical obligation rooted in classical Greek practice. However, there is evidence that patients often suffer from uncontrolled and unnecessary pain. This is inconsistent with the leges artis, and its practical implications merit a bioethical analysis. Several factors have been identified as causes of uncontrolled and unnecessary pain, which deprive patients from receiving appropriate treatments that theoretically they have the right to access. Important factors include (with considerable regional, financial, and cultural differences) the following: 1) failure to identify pain as a priority in patient care; 2) failure to establish an adequate physician–patient relationship; 3) insufficient knowledge regarding adequate prescription of analgesics; 4) conflicting notions associated with drug-induced risk of tolerance and fear of addiction; 5) concerns regarding “last-ditch” treatments of severe pain; and 6) failure to be accountable and equitable. Objective The aim of this article was to establish that bioethics can serve as a framework for addressing these challenging issues and, from theoretical to practical approaches, bioethical reflection can contextualize the problem of unrelieved pain. Methods This article is organized into three parts. First, we illustrate that pain management and its undertreatment are indeed ethical issues. The second part describes possible ethical frameworks that can be combined and integrated to better define the ethical issues in pain management. Finally, we discuss possible directions forward to improve ethical decision making in pain management.

To compare the efficacy of diamorphine administered by a patient-controlled pump (patient-controlled analgesia) with intramuscular administration for pain relief in labour. Randomised controlled trial. The South Glasgow University Hospitals NHS Trust. Primigravidae and multigravidae in labour at term (37-42 weeks). Women were randomised in labour to the study (patient-controlled analgesia) or control group (intramuscular). Randomisation was achieved through a random permuted block design stratified by parity. Study group women were given a loading dose of 1.2 mg diamorphine intravenously and then attached to the pump. Control group women received intramuscular diamorphine as per hospital protocol. Participants were also given 3 mg of buccal Stemetil. Data were collected throughout labour and at six postnatal weeks. Analgesia requirements during labour and women's satisfaction with the method of pain relief. Women in the study group (patient-controlled analgesia) used significantly less diamorphine than women in the control group (intramuscular) but were significantly more likely to state that they were very dissatisfied with their use of diamorphine and were significantly more likely to opt out of the trial before the birth of the baby. The majority of women in both groups used other analgesia concurrent with diamorphine such as Entonox, aromatherapy or TENS. Patient-controlled analgesia administration of diamorphine for the relief of pain in labour offers no significant advantages over intramuscular administration. The results also suggest that diamorphine is a poor analgesic for labour pain irrespective of the mode of administration.

Current strategies for the restoration of adequate lordosis during lumbar fusion

Not restoring the adequate lumbar lordosis during lumbar fusion surgery may result in mechanical low back pain, sagittal unbalance and adjacent segment degeneration. The objective of this work is to describe the current strategies and concepts for restoration of adequate lordosis during fusion surgery. Theoretical lordosis can be evaluated from the measurement of the pelvic incidence and from the analysis of spatial organization of the lumbar spine with 2/3 of the lordosis given by the L4-S1 segment and 85% by the L3-S1 segment. Technical aspects involve patient positioning on the operating table, release maneuvers, type of instrumentation used (rod, screw-rod connection, interbody cages), surgical sequence and the overall surgical strategy. Spinal osteotomies may be required in case of fixed kyphotic spine. AP combined surgery is particularly efficient in restoring lordosis at L5-S1 level and should be recommended. Finally, not one but several strategies may be used to achieve the need for restoration of adequate lordosis during fusion surgery. PMID:25621216

Pain and symptom control. Patient rights and physician responsibilities.

PubMed

Emanuel, E J

1996-02-01

In considering the care of patients with incurable and terminal diseases, there are three types of interventions: (1) palliative care and symptom management; (2) experimental therapies; and (3) active life-ending interventions. Relief of pain, other symptoms, and suffering should be the basic and standard treatment; the other interventions are meant to supplement, not replace, this intervention. This means the physician's primary obligation is to inform patients about the options for palliative care and to provide quality palliative care. Thus, physicians who care for terminally ill patients have an obligation to keep their knowledge base and skills in palliative care current. In those circumstances in which a patient's needs exceeds the physician's knowledge and skills, physicians have a responsibility to refer the patient to a palliative care specialist. With regard to experimental therapies, physicians must obtain full informed consent, provide especially accurate data on the risks and benefits of experimental therapies, and ensure that the patient understands the aims of the proposed therapy. Regarding active life-ending therapies, physicians have the obligation to withhold or withdraw life-sustaining treatment if the patient so desires and to provide adequate pain medication even if this hastens death. Even if euthanasia or physician-assisted suicide are legalized, there is unlikely to be an obligation to provide this intervention.

Liposuction is a common cosmetic surgical procedure, which requires analgesia for postoperative pain. Transcutaneous electrical nerve stimulation (TENS) has been used for postoperative pain relief; however, there is no evidence of its effectiveness in liposuction patients and this is the focus of this paper. A prospective, randomized, double-blind, controlled trial was conducted with 42 adult patients who underwent liposuction. Patients were randomly allocated to either the TENS group (active TENS) or control group (sham TENS). All patients received morphine (0.1 mg/kg) and dipyrone 1 g immediately after surgery; TENS was delivered 2 h later. The primary outcome was pain intensity. Secondary outcomes were analgesic requirement, number and types of adverse effects of TENS, quality of pain, treatment success, and patient satisfaction. Postoperative pain was measured using a visual analog scale (VAS) and the Brazilian version of the McGill Pain Questionnaire (Br-MPQ). Patients in the TENS group reported significantly lower pain intensity (P < 0.001, effect size = 0.92) compared with those in the control group. TENS significantly decreased the consumption of analgesics in the postoperative period (P < 0.001). No withdrawals or adverse effects were observed in the TENS group, but 33.3% of patients in the control group reported drowsiness and nausea. About 95 and 38% of patients in the TENS and control groups, respectively, were satisfied with the analgesic treatment. The results indicate that TENS is effective as an adjunct to analgesics for pain relief after liposuction. This journal requires that authors assign a level of evidence to each article.

To investigate the relationship between a micropulse vibration device and pain perception during orthodontic treatment. This study was a parallel group, randomized clinical trial. A total of 58 patients meeting eligibility criteria were assigned using block allocation to one of two groups: an experimental group using the vibration device or a control group (n  =  29 for each group). Patients used the device for 20 minutes daily. Patients rated pain intensity on a visual analog scale at appropriate intervals during the weeks after the separator or archwire appointment. Data were analyzed using repeated measures analysis of variance at α  =  .05. During the 4-month test period, significant differences between the micropulse vibration device group and the control group for overall pain (P  =  .002) and biting pain (P  =  .003) were identified. The authors observed that perceived pain was highest at the beginning of the month, following archwire adjustment. The micropulse vibration device significantly lowered the pain scores for overall pain and biting pain during the 4-month study period.

Pain Control in the Presence of Drug Addiction.

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.

Does ramosetron reduce postoperative emesis and pain after TKA?

2012-06-01

Current pain management protocols involving many anesthetic and analgesic drugs reportedly provide adequate analgesia after TKA. However, control of emetic events associated with the drugs used in current multimodal pain management remains challenging. We determined (1) whether ramosetron prophylaxis reduces postoperative emetic events; and (2) whether it influences pain levels and opioid consumption in patients managed with a current multimodal pain management protocol after TKA. We randomized 119 patients undergoing TKA to receive either ramosetron (experimental group, n = 60) or no prophylaxis (control group, n = 59). All patients received regional anesthesia, preemptive analgesic medication, continuous femoral nerve block, periarticular injection, and fentanyl-based intravenous patient-controlled analgesia. We recorded the incidence of emetic events, rescue antiemetic requirements, complete response, pain level, and opioid consumption during three periods (0-6, 6-24, and 24-48 hours postoperatively). The severity of nausea was evaluated using a 0 to 10 VAS. The ramosetron group tended to have a lower incidence of nausea with a higher complete response and tended to have less severe nausea and fewer rescue antiemetic requirements during the 6- to 24-hour period. However, the overall incidences of emetic events, rescue antiemetic requirements, and complete response were similar in both groups. We found no differences in pain level or opioid consumption between the two groups. Ramosetron reduced postoperative emetic events only during the 6- to 24-hour postoperative period and did not affect pain relief. More efficient measures to reduce emetic events after TKA should be explored. Level I, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

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

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 evaluate whether 550 mg oral naproxen sodium given 1 hour before intrauterine device (IUD) insertion is effective for pain relief as compared with placebo. This was a randomized, double-blind, placebo-controlled trial. The primary outcome was pain with IUD insertion measured on a 100-mm visual analog scale (VAS). Our sample size was calculated to detect a 15-mm difference in VAS scores with 80% power (α=0.05). Secondary outcomes included pain with tenaculum placement, uterine sounding, and 5 and 15 minutes postinsertion. A total of 118 women were enrolled and analyzed (58 in the naproxen sodium arm, 60 in the placebo arm, 97% nulliparous) between May 11, 2015, and March 25, 2016. There were no differences in baseline demographics or reproductive characteristics between arms. There were no differences in median VAS pain scores for the primary outcome of pain with IUD insertion between the naproxen sodium arm compared with the placebo arm (69 compared with 66 mm, P=.89). There were no differences in the secondary outcomes of median VAS pain scores with tenaculum placement (37 compared with 32 mm, P=.97) or uterine sounding (60 compared with 58 mm, P=.66). However, median pain scores postprocedure were lower in the naproxen arm as compared with the placebo arm: 17 compared with 26 mm (P=.01) at 5 minutes and 13 compared with 24 mm (P=.01) at 15 minutes postinsertion.

Despite routine postoperative pain management improves recovery and reduces postoperative morbidity and overall costs, and the availability of a large armamentarium of analgesic techniques and drugs, a significant portion of patients do not receive adequate postoperative pain control. We describe a recovery room (RR) based acute pain service model. Guidelines on postoperative pain and therapeutic protocols were instituted in January 1999. The analgesic endpoint was a visual analogic scale (VAS) below 4 for all surgical patients for the first 48-72 h. The RR, run by one anesthesiologist and 2 nurses and one assistant, acted as a coordination centre. Discharge from the RR was subject to achieving effective analgesia. Nurses of each ward monitored VAS along with vital signs, administered rescue doses if necessary, and reported to the RR nurse when needed. RR nurses monitored the patient at least twice daily and reported to the anesthesiologist. We have distributed an anonymous questionnaire, within surgical wards, to both surgeons and nurses to evaluate their perception of pain management and of this acute pain service (APS) model. VAS was maintained significantly <4. Analgesic drug consumption increased between 1997, 2000 (first year of APS) and 2004. The auditing process confirmed the desire of all professional figures to be informed and involved in acute pain management as part of a coordinated and systematic approach to the surgical patient. A RR-based APS can effectively act as coordinating centre for acute pain treatment without adjunctive personnel.

Jont pain in oldder people The prevalence of chronic pain in older people in the community ranges from 25 to 76% and for those in residential care, it is even higher at 83 to 93%. The most common sites affected are the back, hip, or knee, and other joints. There is increased reporting of pain in women (79%) compared with men (53%). Common conditions include osteoarthritis and, to a lesser extent, the inflammatory arthropathies such as rheumatoid arthritis. The differential diagnosis includes non-articular pain such as vascular limb pain and nocturnal cramp, some neuropathic pain conditions (such as compressive neuropathies and postherpetic neuralgia), soft tissue disorders such as fibromyalgia and myofascial pain syndromes. In addition to an assessment of pain intensity, a biopsychosocial model should be adopted to ascertain the effect of the pain on the patient's degree of background pain at rest. The disease is often localised to the large load-bearing joints, predominantly the hips and knees. In contrast to osteoarthritis, the inflammatory arthritides typically present with symmetrical swollen, stiff, and painful small joints of the hands and feet, usually worse in the morning.

To review the prevalence and etiology of pain in persons with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), and issues and considerations for pain management in this patient population. Research studies, review articles, and books related to pain in persons with HIV/AIDS. Pain is a common problem for individuals with HIV/AIDS that is often poorly managed and net well documented. Many of these patients have multiple, coexisting illnesses that are painful. Adequate assessment of the underlying cause will help in the treatment or eradication of pain. The management of pain in persons with HIV/AIDS is an important responsibility for oncology nurses because increasing numbers of persons with HIV/AIDS are being treated for neoplastic complications, cytopenias, or being referred to hospice care.

Afghanistan, poppies, and the global pain crisis.

The World Health Organization has reported that somewhere between 30-86 million people suffer from moderate to severe pain due to cancer, HIV/AIDS, burns, wounds and other illnesses annually and do not have access to proper opiate anesthetics to control the pain [1]. The vast majority of these people live in poor nations where medicinal opiates are either too expensive or not readily available. In this paper, it is argued that access to adequate healthcare is a human right and that adequate healthcare includes management of pain. The solution to this problem may be in Afghanistan, a country now overwhelmed with poverty and war. Afghanistan is the world's leading producer of heroin. The increase in heroin production in Afghanistan has caused the United States and the international community to begin to eradicate Afghanistan's poppy fields leading to increased poverty among poppy farmers. This paper proposed a paradigm that can be implemented in Afghanistan which would allow for Afghan farmers to continue growing their poppy crop for medicinal opiates like morphine for poor nations. The paradigm covers all parameters of medicinal opiates production including licensing, security, cultivation, harvest, and factory production of medicinal opiates. The paradigm proposed is less expensive than eradication, brings honest income to Afghan farmers and the new Afghan nation, and can eventually lead to Afghanistan acquiring a respectable role in the world community. In closing, a full ethical analysis of the paradigm is included to justify the arguments made in the paper.

Despite a limited understanding of the exact mechanism, corticosteroids are commonly employed for pain control in patients with bone metastases. The aim of this review was to evaluate the efficacy of corticosteroid-mediated pain control in patients with bone metastases associated with solid cancers. A literature search was conducted using OVID MEDLINE and Embase databases (from 1946 up to July 19, 2016). Studies involving patients with bone metastases receiving corticosteroids as the primary means of pain control were included. Screening and data extraction were conducted by paired reviewers, with consensus established by discussion, or a third adjudicator. A total of 12 studies were included. Rates of pain relief achieved with corticosteroid use varied from 30 to 70%, but generally reflected moderate pain control. Corticosteroid use significantly reduced the incidence of pain flare alongside radiotherapy, reportedly by almost half of baseline pain severity. Adverse events were not documented consistently across studies, though grade two to three hyperglycemia was noted in approximately 2% of patients by some studies. Recent evidence suggests that short-term corticosteroid use may provide moderate pain and pain flare control with radiotherapy for patients with bone metastases. The risk of developing adverse effects should be carefully considered prior to therapy initiation on a case-by-case basis.

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

BACKGROUND: Adverse health care events are injuries occurring as a result of patient care. Significant acute pain is often caused by medical and surgical procedures in children, and it has been argued that undermanaged pain should be considered to be an adverse event. Indicators are often used to identify other potential adverse events. There are currently no validated indicators for undertreated pediatric pain. OBJECTIVES: To develop a preliminary list of indicators of undermanaged pain in hospitalized pediatric patients. METHODS: The Delphi technique was used to survey experts in pediatric pain management and quality improvement. The first round used an electronic questionnaire to ask: “In your opinion, what indicators would signify that acute pain in a child has not been adequately controlled?” Responses were grouped together in semantically similar themes, providing a list of possible adverse event indicators. Using this list, an electronic questionnaire was developed for round 2 asking respondents to indicate the importance of each potential indicator. RESULTS: All but one indicator achieved a level of consensus ≥70%. Separate indicators emerged for postoperative and procedural pain. An additional distinction was made between indicators that could be identified by chart review and those requiring observation of practice and assessment from the child or parent. DISCUSSION: The adverse care indicators developed in the present study require further refinement. There is a need to test their clinical usability and to determine whether these indicators actually identify undermanaged pain in clinical practice. The present study is an important first step in identifying undermanaged pain in hospital and treating it as an adverse event. CONCLUSION: The adverse care indicators developed in the present study are the first step in conceptualizing mismanaged pain as an adverse event. PMID:24093121

Chronic pain after open inguinal hernia repair.

PubMed

Nikkolo, Ceith; Lepner, Urmas

2016-01-01

Following the widespread use of mesh repairs, recurrence rates after inguinal hernia surgery have become acceptable and focus has shifted from recurrence to chronic pain. Although pain can be controlled with analgesics, chronic postsurgical pain is a major clinical problem, which can significantly influence the patient's quality of life. The rate of chronic pain after inguinal hernia mesh repair can reach 51.6%. The reasons for posthernioplasty chronic pain are often unclear. It has been linked to nerve injury and nerve entrapment, but there is also association between the rate of chronic pain and the type of mesh used for hernia repair. As there are >160 meshes available in the market, it is difficult to choose a mesh whose usage would result in the best outcome. Different mesh characteristics have been studied, among them weight of mesh has probably gained the most attention. The choice of adequate therapy for chronic groin pain after inguinal hernia repair is controversial. The European Hernia Society recommends that a multidisciplinary approach at a pain clinic should be considered for the treatment of chronic postoperative pain. Although surgical treatment of chronic posthernioplasty pain is limited because of the lack of relevant research data, resection of entrapped nerves, mesh removal in the case of mesh related pain or removal of fixation sutures can be beneficial for the patient with severe pain after inguinal hernia surgery. One drawback of published studies is the lack of consensus over definition of chronic pain, which makes it complicated to compare the results of different studies and to conduct meta-analyses and systematic reviews. Therefore, a uniform definition of chronic pain and its best assessment methods should be developed in order to conduct top quality multicenter randomized trials. Further research to develop meshes with optimal parameters is of vital importance and should be encouraged.

There are numerous published references to use of nettle sting for arthritis pain but no randomized controlled trials have been reported. We conducted a randomized controlled double-blind crossover study in 27 patients with osteoarthritic pain at the base of the thumb or index finger. Patients applied stinging nettle leaf (Urtica dioica) daily for one week to the painful area. The effect of this treatment was compared with that of placebo, white deadnettle leaf (Lamium album), for one week after a five-week washout period. Observations of pain and disability were recorded for the twelve weeks of the study. After one week's treatment with nettle sting, score reductions on both visual analogue scale (pain) and health assessment questionnaire (disability) were significantly greater than with placebo (P = 0.026 and P = 0.0027).

Morphine consumption can vary widely between individuals even for identical surgical procedures. As mu-opioid receptor (OPRM1) is known to modulate pain perception and mediate the analgesic effects of opioid compounds in the central nervous system, we examined the influence of two OPRM polymorphisms on acute post-operative pain and morphine usage in women undergoing elective caesarean delivery. Data on self-reported pain scores and amount of total morphine use according to patient-controlled analgesia were collected from 994 women from the three main ethnic groups in Singapore. We found statistically significant association of the OPRM 118A>G with self-administered morphine during the first 24-hour postoperative period both in terms of total morphine (p = 1.7 x 10(-5)) and weight-adjusted morphine (p = 6.6 x 10(-5)). There was also significant association of this OPRM variant and time-averaged self-rated pain scores (p = 0.024). OPRM 118G homozygotes used more morphine and reported higher pain scores than 118A carriers. Other factors which influenced pain score and morphine usage include ethnicity, age and paying class. Our results suggest that ethnicity and OPRM 118A>G genotype are independent and significant contributors to variation in pain perception and postoperative morphine use in patients undergoing cesarean delivery.

Purpose: Pain is a common symptom among cancer patients, yet many patients do not receive adequate pain management. Few data exist quantifying analgesic use by radiation oncology patients. This study evaluated the causes of pain in cancer patients and investigated the reasons patients fail to receive optimal analgesic therapy. Methods and Materials: An institutional review board-approved, Internet-based questionnaire assessing analgesic use and pain control was posted on the OncoLink (available at (www.oncolink.org)) Website. Between November 2005 and April 2006, 243 patients responded. They were predominantly women (73%), white (71%), and educated beyond high school (67%) and had breast (38%), lungmore » (6%), or ovarian (6%) cancer. This analysis evaluated the 106 patients (44%) who underwent radiotherapy. Results: Of the 106 patients, 58% reported pain from their cancer treatment, and 46% reported pain directly from their cancer. The pain was chronic in 51% and intermittent in 33%. Most (80%) did not use medication to manage their pain. Analgesic use was significantly less in patients with greater education levels (11% vs. 36%, p = 0.002), with a trend toward lower use by whites (16% vs. 32%, p 0.082) and women (17% vs. 29%, p = 0.178). The reasons for not taking analgesics included healthcare provider not recommending medication (87%), fear of addiction or dependence (79%), and inability to pay (79%). Participants experiencing pain, but not taking analgesics, pursued alternative therapies for relief. Conclusions: Many radiation oncology patients experience pain from their disease and cancer treatment. Most study participants did not use analgesics because of concerns of addiction, cost, or failure of the radiation oncologist to recommend medication. Healthcare providers should have open discussions with their patients regarding pain symptoms and treatment.« less

Objective: Phantom limb pain is a condition frequently experienced after amputation. One treatment for phantom limb pain is traditional mirror therapy, yet some patients do not respond to this intervention, and immersive virtual reality mirror therapy offers some potential advantages. We report the case of a patient with severe phantom limb pain following an upper limb amputation and successful treatment with therapy in a custom virtual reality environment. Methods: An interactive 3-D kitchen environment was developed based on the principles of mirror therapy to allow for control of virtual hands while wearing a motion-tracked, head-mounted virtual reality display. The patient used myoelectric control of a virtual hand as well as motion-tracking control in this setting for five therapy sessions. Pain scale measurements and subjective feedback was elicited at each session. Results: Analysis of the measured pain scales showed statistically significant decreases per session [Visual Analog Scale, Short Form McGill Pain Questionnaire, and Wong-Baker FACES pain scores decreased by 55 percent (p=0.0143), 60 percent (p=0.023), and 90 percent (p=0.0024), respectively]. Significant subjective pain relief persisting between sessions was also reported, as well as marked immersion within the virtual environments. On followup at six weeks, the patient noted continued decrease in phantom limb pain symptoms. Conclusions: Currently available immersive virtual reality technology with myolectric and motion tracking control may represent a possible therapy option for treatment-resistant phantom limb 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.

The authors of this study compared the effects of pilates exercises and connective tissue massage (CTM) on pain intensity; pain-pressure threshold; and tolerance, anxiety, progress, and health-related quality of life in females with fibromyalgia. It was a pilot, assessor masked, randomized controlled trial conducted between January and August of 2013. Twenty-one women with fibromyalgia were randomly assigned to the pilates exercise program (six of whom did not complete the program), and 22 were randomly assigned to CTM (one of whom did not complete this program). Each group received the assigned intervention three times per week during a 4-week period. The Visual Analogue Scale, algometry, State-Trait Anxiety Inventory, Fibromyalgia Impact Questionnaire, and Nottingham Health Profile were used at baseline and at the end of treatments. Significant improvements were found in both groups for all parameters. However, the scores for pain-pressure threshold were significantly elevated and the symptoms of anxiety were significantly diminished in the exercise group compared to the massage group. Thus, exercise and massage might be used to provide improvements in women with fibromyalgia. The exercise group showed more advantages than the massage group and thus might be preferred for patients with fibromyalgia. However, an adequately powered trial is required to determine this with certainty.

Pain is highly prevalent in older adults, especially those in institutional settings such as nursing homes. The presence of dementia may increase the risk of underdiagnosed and undertreated pain. Pain assessment tools are not regularly used in clinical practice, however, there are indications that the regular use of pain assessments tools may influence the recognition of pain by nursing staff and thereby affect pain management. To assess whether regular pain assessment using a pain assessment tool is associated with changes in i) pain scores and ii) analgesic use in nursing home residents with severe dementia. Cluster-randomised controlled trial. The study was conducted in 16 nursing homes in four counties in Norway. A total of 112 nursing home residents aged 65 years and older with dementia who lacked the capacity for self-reporting pain or were non-verbal. The experimental group were regularly assessed pain with a standardised pain scale (the Doloplus-2) twice a week for a 12-week intervention period. The control group received usual care. The primary outcome was pain score measured with the Doloplus-2, and the secondary outcome was analgesic use (oral morphine equivalents and milligram/day paracetamol). Data on the outcomes were collected at baseline and at the end of week 12. The nursing staff in both the experimental and the control groups received training to collect the data. Linear mixed models were used to assess possible between-group difference over time. No overall effect of regular pain assessment was found on pain score or analgesic use. The mean score of Doloplus-2 and analgesic use remained unchanged and above the established cut-off in both groups. The current intervention did not change analgesic use or pain score compared with the control condition. However, there is not sufficient evidence to conclude that regular pain assessment using a pain assessment tool is not clinically relevant. Furthermore, our results indicated that pain continued to be

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.

Despite lack of efficacy data, the majority of first-trimester surgical abortions are performed with a paracervical block. Women may be unnecessarily exposed to a painful injection and potentially noxious medication. Our objective was to estimate the effect of a paracervical block and the effect of gestational age on patient pain perception. This was a randomized, single-blind trial of patients undergoing abortion receiving paracervical block or sham stratified by gestational age (early: less than 8 weeks of gestation, n=60; late: 8-10 6/7 weeks of gestation, n=60). Premedicated with ibuprofen and lorazepam, all participants received 2 mL 1% buffered lidocaine injected at the tenaculum site followed by a slow, deep injection of 18 mL at four sites (block) or no injection (sham) with a 3-minute wait. The primary outcome was dilation pain (100-mm visual analog scale). Secondary outcomes included pain at additional time points, satisfaction, need for more analgesics, and adverse events. Full enrollment occurred (n=120). We used intent-to-treat analysis. Demographics did not differ between groups. Paracervical block administration was painful (mean 55 mm compared with sham 30 mm, P<.001) but decreased dilation pain (42 mm compared with 79 mm, P<.001) and aspiration pain (63mm compared with 89 mm, P<.001). These results were consistent for both gestational age strata; however, paracervical block benefit was greater at an earlier gestation. Satisfaction scores with pain control and the procedure were significantly higher in the block group. Although paracervical block is painful, it reduces first-trimester abortion pain regardless of gestational age, but the benefit on dilation pain was greater at earlier gestations.

Many studies report that people with temporomandibular disorders (TMD) are more sensitive to experimental pain stimuli than TMD-free controls. Such differences in sensitivity are observed in remote body sites as well as in the orofacial region, suggesting a generalized upregulation of nociceptive processing in TMD cases. This large case-control study of 185 adults with TMD and 1,633 TMD-free controls measured sensitivity to painful pressure, mechanical cutaneous, and heat stimuli, using multiple testing protocols. Based on an unprecedented 36 experimental pain measures, 28 showed statistically significantly greater pain sensitivity in TMD cases than controls. The largest effects were seen for pressure pain thresholds at multiple body sites and cutaneous mechanical pain threshold. The other mechanical cutaneous pain measures and many of the heat pain measures showed significant differences, but with lesser effect sizes. Principal component analysis (PCA) of the pain measures derived from 1,633 controls identified five components labeled: (1) heat pain ratings, (2) heat pain aftersensations and tolerance, (3) mechanical cutaneous pain sensitivity, (4) pressure pain thresholds, and (5) heat pain temporal summation. These results demonstrate that, compared to TMD-free controls, chronic TMD cases are more sensitive to many experimental noxious stimuli at extra-cranial body sites, and provides for the first time the ability to directly compare the case-control effect sizes of a wide range of pain sensitivity measures.

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.

Pain is considered as the fifth vital sign, and the need to control pain after surgery emphasizes its importance. Pain after surgery leads to unpleasant outcomes and effects on different mechanisms thus causes fundamental changes in the metabolism of the body of susceptible people. Accordingly, the current article aimed to compare two methods of pain control by the patient using PCA pumps compared to medicine injection to ease the pain by nurses. Methodology: In the current research, a single-blind clinical trial of 70 patients as nominees of undergoing open-heart surgery at Shiraz Ordibehesht Hospital during 12 months was examined. The patients randomly divided into two groups of 35 patients with pain control by analgesia pumps of PCA and by NCA. The pain intensity was analyzed by visual analog scale (VAZ) and the sedation degree was examined based on the factors such as the Richmond sedation, nausea and vomiting and respiratory depression induced by opioids and analgesic effects, arterial oxygen saturation, patient satisfaction, ventilation duration for up to 48 hours after surgery. For data analysis, statistical software SPSS was used. Results: No statistically clear distinction was seen in the status of nausea and vomiting as well as in the length of ventilation and the oxygen saturation status between the two groups. In none of the two groups, respiratory depression was observed. There was a statistically notable variation between the two teams regarding satisfaction level. Also, an increasing significant decline in pain intensity was noted in both groups at consecutive times. There was an experimentally meaningful distinction between the two teams regarding degree of sedation (P < 0.001), such that the level of sedation in NCA group was higher (P < 0.001). Conclusion: The use of PCA pump in acute pain control after open cardiac surgery was better than the NCA. In the case of using the PCA pump, in addition to the psychological effect, the pump could control

Neuropathic pain is often underestimated and not adequately treated. The DN4 scale is very useful for its identification since it will benefit from pharmacological and non-pharmacological specific alternative care. The pathophysiological mechanisms involve the hyperexcitability of nociceptive pathways or decreased inhibitory descending controls that will be the target of pharmacological treatments. Frontline molecules are antidepressants (tricyclics and mixed serotonin and norepinephrine reuptake inhibitors) and antiepileptics (α2δ calcium channel inhibitors). However, these drugs will only have a partial efficacy on pain. The therapeutic strategy is based on reasonable goals, starting with a monotherapy adapted to the patient's symptoms and comorbidities and increased step by step. Patient compliance to contract is essential and requires clear and complete information. The impact on profession, social and family integration should rapidly be taken into account. In case of inefficiency, a change of the first-line treatment or an association could be considered. Some indications justify a specific therapy. Patients with resistant chronic pain should be sent to a specialized centre. New drugs are being studied and non-pharmacological support must be evaluated.

Although pain management during periodontal treatment usually is achieved with anesthesia, alternative methods are available. The authors conducted a study to evaluate the analgesic effect of immersive virtual reality (VR) during periodontal scaling and root planing (SRP) procedures. The authors recruited 38 patients. They used a within-patient/split-mouth design. Patients received SRP under three treatment conditions in three quadrants. The three conditions were control, watching a movie and VR. After each SRP procedure, patients responded to questions about their discomfort and/or pain by using a visual analog scale (VAS) (range, 0 to 10 in which lower numbers indicate less pain or discomfort). The authors also recorded patients' blood pressure (BP) and pulse rate (PR). Patients were asked which of the three treatment modalities they preferred. The mean (+/- standard deviation) VAS scores for five questions pertaining to control, movie and VR were 3.95 +/- 2.1, 2.57 +/- 1.8 and 1.76 +/- 1.4, respectively. Paired t tests revealed that VAS scores were significantly lower during VR compared with the movie (P <.001) and control (P <.001) conditions. Similarly, BP and PR were lowest during VR, followed by the movie and control conditions. Patients reported that they preferred the VR condition. The results of this study suggest that use of immersive VR distraction may be an effective method of pain control during SRP procedures. Practitioners can use immersive VR distraction for pain control during SRP procedures.

Self-monitoring of blood glucose empowers diabetes patients to effectively control their blood glucose (BG) levels. A potential barrier to frequent BG controls is lancing pain, intrinsically linked to pricking the finger several times a day. In this study, we compared different state-of-the-art lancing devices from leading manufacturers regarding lancing pain, and we intended to identify lancing devices that are less painful. First, 165 subjects compared 6 different BG monitoring systems-consisting of a lancing device and a BG meter-at home for 36 days and at least 3 BG tests per day. Second, the subjects directly compared 6 different lancing devices-independent from a BG meter-in a laboratory setting. The test results were collected in questionnaires, and lancing pain was rated on a numerical rating scale. One hundred fifty-seven subjects were included in the analysis. Accu-Chek BG monitoring systems were significantly (p < or = .006) preferred to competitor BG monitoring systems and were rated by >50% of the subjects as "less painful" than competitor BG monitoring systems. Accu-Chek lancing devices were significantly (p < .001) preferred to competitor lancing devices and were rated by >60% of the subjects as "less painful" than competitor lancing devices. We found significant differences in lancing pain between lancing devices. Diabetes patients clearly preferred lancing devices that cause less lancing pain. In order to improve patient compliance with respect to an adequate glycemic control, the medical staff should preferentially prescribe lancing devices that cause less lancing pain. 2009 Diabetes Technology Society.

Despite many positive developments, postoperative pain and its treatment is still not always given the necessary attention. Severe pain after surgical procedures affects a significant proportion of patients. This very fact is not only detrimental to the immediate recovery process, but can also form the basis for the development of chronic pain conditions.An adequate and effective management of perioperative pain requires appropriate organizational structures. This multidisciplinary paper which was initiated by the Austrian Society for Anaesthesiology and Intensive Care and the Austrian Pain Society and developed together with numerous specialist and professional societies dealing with the subject aims at supporting the organization of perioperative pain management structures and to make best use of proven concepts. Additional recommendations describe specific interventions for selected types of intervention.

, including standing and walking, lifting and bending. Each sequence was rated on a four-point scale reflecting the degree to which adequate posture and gait were achieved. The final scale consists of 13 items with an inter-rater-reliability of 0.91 (Cronbach Alpha). The data for 283 persons attending in 31 courses in different industrial and administrative settings was used to evaluate the outcome. A marked decrease in pain episodes and an increase in health status and wellbeing were reported. Behaviour that was learned in the course had been incorporated into everyday activities at the worksite. The behavioural observation method was utilized in a subgroup of this sample who were on the staff of a university hospital. The study used a 2x2 repeated-measures design with the between-subject factor of treatment condition (training vs nontraining) and the within-subject factor of assessment period (pre-treatment=t1, post-treatment=12, 9-month follow-up=t3) allowing for analyses of variance (AN-OVA). Following a matched-pair design, for every person that participated in the training a control person was included in the study to allow control for gender, age, and occupation. This sample consists of 74 pairs and comprises nurses, administration personnel, physicians and physical therapists. Most (80%) are female. So far only 28 pairs have been reassessed at t3. A comparison of the overall scores obtained with the above items before and after treatment demonstrates an extremely significant interaction effect, indicating an increase of adequate behaviours in the treatment group. At the follow-up assessment, the observed effect was maintained. (1) A back school training for the worksite results in a decreased frequency of back pain episodes and an increase in reported health status and wellbeing. (2) The effects of behavioural training of posture, gait, and activities of daily living in hospital staff are clearly demonstrated by observational methods. (3) Assuming that present posture

We compared the effectiveness of liposomal bupivacaine to ropivacaine, each as part of multimodal pain management, in total knee arthroplasty (TKA) postoperative pain control. This prospective, double blind study randomized 96 TKA patients into a control group (periarticular injection of ropivacaine, ketorolac, morphine, and epinephrine in saline; 100cc) or an experimental group (periarticular injection of bupivacaine, ketorolac, morphine, and epinephrine in saline; 80cc plus 1.3% liposomal bupivacaine 20cc; total injection 100cc). The postoperative use of narcotics, visual analog pain scores, hours to ambulate 100 feet, and length of hospital stay were recorded. There was no significant difference between the two groups (control N = 49, experiment N = 47) in mean narcotic use per hour, total narcotic use during hospital stay, time to ambulate 100 feet, length of hospital stay, or visual analog score for pain postoperatively. There is no benefit in the use of liposomal bupivacaine compared with ropivacaine for postoperative pain control in TKA. Copyright © 2017 Elsevier Inc. All rights reserved.

To compare the short-term and medium-term effect of Functional Fascial Taping to placebo taping on pain and function in people with non-specific low back pain. A pilot randomized controlled trial with a 2-week intervention, and 2-, 6- and 12-week follow-up. Individuals with non-specific low back pain recruited from local communities. Forty-three participants with non-specific low back pain for more than 6 weeks were randomized into either Functional Fascial Taping group (n = 21) or placebo group (n = 22). The intervention group was treated with Functional Fascial Taping while the control group was treated with placebo taping. Both groups received four treatments over 2 weeks. Worst and average pain and function were assessed at baseline, after the 2-week intervention, and at 6 and 12 weeks follow-up. The Functional Fascial Taping group demonstrated significantly greater reduction in worst pain compared to placebo group after the 2-week intervention (P = 0.02, effect size = 0.74; 95% confidence interval 0.11-1.34). A higher proportion of participants in Functional Fascial Taping group attained the minimal clinically important difference in worst pain (P = 0.007) and function (P = 0.007) than those in placebo group after the 2-week intervention. There were no significant differences in either group's disability rating or clinically important difference in average pain at any time. Functional Fascial Taping reduced worst pain in patients with non-acute non-specific low back pain during the treatment phase. No medium-term differences in pain or function were observed.

Interepisode Sleep Bruxism Intervals and Myofascial Face Pain.

2017-08-01

Sleep bruxism (SB) is considered as a possible etiological factor for temporomandibular disorder (TMD) pain. However, polysomnographic (PSG) studies, which are current "gold standard" diagnostic approach to SB, failed to prove an association between SB and TMD. A possible explanation could be that PSG studies have considered only limited characteristics of SB activity: the number of SB events per hour and, sometimes, the total duration of SB per night. According to the sports sciences literature, lack of adequate rest time between muscle activities leads to muscle overloading and pain. Therefore, the aim of this study was to determine whether the intervals between bruxism events differ between patients with and without TMD pain. Two groups of female volunteers were recruited: myofascial TMD pain group (n=124) and non-TMD control group (n=46). From these groups, we selected 86 (69%) case participants and 37 (80%) controls who had at least two SB episodes per night based on PSG recordings. A linear mixed model was used to compare case and control groups over the repeated observations of interepisode intervals. The duration of interepisode intervals was statistically similar in the case (mean [standard deviation {SD}] 1137.7 [1975.8] seconds)] and control (mean [SD] 1192.0 [1972.0] seconds) groups. There were also a similar number of SB episodes per hour and a total duration of SB episodes in both groups. The current data fail to support the idea that TMD pain can be explained by increasing number of SB episodes per hour of sleep or decreasing the time between SB events. © Sleep Research Society 2017.

We reviewed previous publications on post-orgasmic pain with reference to prevalence, epidemiology and treatment options, using the Ovid and PubMed (updated May 2006) databases to comprehensively search MEDLINE for reports on post-orgasmic pain that included peer-reviewed English-language articles. Official proceedings of internationally known scientific societies were also assessed. Because of the heterogeneity of the studies we did not apply meta- analytic techniques to the data. The incidence of post-orgasmic pain is 1-9.7%. The ejaculatory pain is associated with prostatitis, chronic pelvic pain syndrome, benign prostatic hyperplasia, and ejaculatory duct obstruction; it is also described in patients after procedures like radical prostatectomy. Aetiopathogenic theories include those referring to bladder neck closure and pudendal neuropathy. The treatment options vary from self-care, a 'perineal hyperprotection programme' to medication with the alpha-blocker, topiramate, and even surgical procedures like removing a section of the sacrotuberous ligament, neurolysis of the pudendal nerve or removing a section of the sacrospinous ligament. This is the first update of the subject, with reference to prevalence, epidemiology and treatment options. There is a need for adequately powered, prospective randomized trials on aetiology and treatment options.

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.

To examine the effect of depression treatment on medical and social outcomes for individuals with chronic pain and depression. People with chronic pain and depression have worse health outcomes than those with chronic pain alone. Little is known about the effectiveness of depression treatment for this population. Propensity score-weighted analyses, using both waves (1997-1998 and 2000-2001) of the National Survey of Alcohol, Drug, and Mental Health Problems, were used to examine the effect of a) any depression treatment and b) minimally adequate depression treatment on persistence of depression symptoms, depression severity, pain severity, overall health, mental health status, physical health status, social functioning, employment status, and number of workdays missed. Analyses were limited to those who met Composite International Diagnostic Interview Short-Form criteria for major depressive disorder, reported having at least one chronic pain condition, and completed both interviews (n = 553). Receiving any depression treatment was associated with higher scores on the mental component summary of the Medical Outcomes Study Short Form-12, indicating better mental health (difference = 2.65 points, p = .002) and less interference of pain on work (odds ratio = 0.57, p = .02). Among those receiving treatment, minimal adequacy of treatment was not significantly associated with better outcomes. Depression treatment improves mental health and reduces the effects of pain on work among those with chronic pain and depression. Understanding the effect of depression treatment on outcomes for this population is important for employers, healthcare providers treating this population, and policymakers working in this decade of pain control and research to improve care for chronic pain sufferers.

The aim of this study was to compare the effectiveness of a combination of aquatic exercise and pain neurophysiology education with aquatic exercise alone in chronic low back pain patients. Single-blind randomized controlled trial. Outpatient clinic. Sixty-two chronic low back pain patients were randomly allocated to receive aquatic exercise and pain neurophysiology education (n = 30) or aquatic exercise alone (n = 32). Twelve sessions of a 6-week aquatic exercise programme preceded by 2 sessions of pain neurophysiology education. Controls received only 12 sessions of the 6-week aquatic exercise programme. The primary outcomes were pain intensity (Visual Analogue Scale) and functional disability (Quebec Back Pain Disability Scale) at the baseline, 6 weeks after the beginning of the aquatic exercise programme and at the 3 months follow-up. Secondary outcome was kinesiophobia (Tampa Scale of Kinesiophobia). Fifty-five participants completed the study. Analysis using mixed-model ANOVA revealed a significant treatment condition interaction on pain intensity at the 3 months follow-up, favoring the education group (mean SD change: -25.4± 26.7 vs -6.6 ± 30.7, P < 0.005). Although participants in the education group were more likely to report perceived functional benefits from treatment at 3 months follow-up (RR=1.63, 95%CI: 1.01-2.63), no significant differences were found in functional disability and kinesiophobia between groups at any time. This study's findings support the provision of pain neurophysiology education as a clinically effective addition to aquatic exercise. © The Author(s) 2014.

Nonpharmaceutical Pain Control Adjuncts During First-Trimester Aspiration Abortion: A Review.

First-trimester aspiration abortion is associated with moderate to severe pain. The effectiveness of adjunctive therapies for pain control is not well understood. This critical review summarizes the existing literature regarding nonpharmacologic interventions to reduce pain during first-trimester office-based abortion. PubMed and Google Scholar were searched using the following search terms in various combinations: "abortion," "pain," "nonpharmaceutical," "nonpharmacologic," "anxiety," "fear," "pain management," "pain reduction," "anxiety reduction," "complementary and alternative medicine," and "integrative medicine." Seven articles meeting inclusion criteria were entered into a matrix for comparison. Findings from each study are summarized describing design, results, and themes. These results are summarized to provide evidence-based clinical guidelines and identify areas for further research. None of the nonpharmacologic interventions studied were significantly associated with a reduction in pain or anxiety scores. However, women in many studies strongly endorsed future use of these techniques. The data included in this critical review did not demonstrate a relationship between the nonpharmacologic interventions and pain or anxiety scores, yet participants endorsed these as positive and helpful. Women found value in these supportive interventions, and ongoing investigation into these techniques is warranted. © 2016 by the American College of Nurse-Midwives.

The Integration of Negative Affect, Pain, and Cognitive Control in the Cingulate Cortex

Preface It has been argued that emotion, pain, and cognitive control are functionally segregated in distinct subdivisions of the cingulate cortex. But recent observations encourage a fundamentally different view. Imaging studies indicate that negative affect, pain, and cognitive control activate an overlapping region of dorsal cingulate, the anterior midcingulate cortex (aMCC). Anatomical studies reveal that aMCC constitutes a hub where information about reinforcers can be linked to motor centers responsible for expressing affect and executing goal-directed behavior. Computational modeling and other kinds of evidence suggest that this intimacy reflects control processes that are common to all three domains. These observations compel a reconsideration of dorsal cingulate’s contribution to negative affect and pain. PMID:21331082

Krill oil is an edible oil extracted from krill, a small red-colored crustacean found in the Antarctic Ocean. The administration of krill oil is reported to mitigate inflammation in patients with cardiac disease, rheumatoid arthritis, or osteoarthritis. However, the effect of krill oil on mild knee pain has not yet been determined. To assess the effect of krill oil on mild knee pain. A randomized, double-blind, parallel-group, placebo-controlled trial of fifty adults (38-85 years old) with mild knee pain attending the Fukushima Orthopedic Clinic (Tochigi, Japan) between September 2014 and March 2015. Participants were randomized to receive 2 g per day of either krill oil or an identical placebo for 30 days. The primary outcome was improvement in subjective symptoms of knee pain as assessed by the Japanese Knee Osteoarthritis Measure (JKOM) and Japanese Orthopaedic Association score (JOA). Secondary outcomes included blood and urine biochemical parameters. Both the placebo and krill oil groups showed significant improvements in the questions in the JKOM and JOA questionnaires after administration. After the intervention, krill oil group showed more improvements than placebo group in two questions regarding the pain and stiffness in knees in JKOM. Controlling for age, sex, weight, and smoking and drinking habits, krill oil significantly mitigated knee pain in sleeping (P < 0.001), standing (P < 0.001) and the range of motion of both right and left knees (both P = 0.011) compared to placebo. Krill oil administration raised plasma EPA (P = 0.048) and EPA/AA ratio (P = 0.003). This study indicates that krill oil administration (2 g/day, 30 days) improved the subjective symptoms of knee pain in adults with mild knee pain. UMIN-CTR; ID UMIN000014413.

Controlling pain and reducing misuse of opioids

Abstract Objective To help family physicians achieve an ethical balance in their opioid prescribing practices. Quality of evidence MEDLINE was searched for English-language articles published between 1985 and 2011. Most available evidence was level III. Main message It is essential to follow practice guidelines when prescribing opioids, except when another course of action is demonstrably justified. In addition, when considering the appropriateness of an opioid prescription, with its many ethical implications, the decision can be usefully guided by the application of the ethical principles of beneficence, nonmaleficence, respect for autonomy, and justice. As well, it is essential to keep current about legal and regulatory changes and provincial electronic registries of opioid prescriptions. Conclusion Physicians need to ensure that their patients’ pain is properly assessed and managed. Reaching optimal pain control might necessitate prescribing opioids. But the obligation to provide pain relief needs to be balanced with an equally important responsibility not to expose patients to risk of addiction and not to create opportunities for drug diversion, trafficking, and the addiction of others. Basic ethical principles can provide a framework to help physicians make ethically appropriate decisions about opioid prescribing. PMID:22611604

To assess the short-term efficacy of transregional interferential current therapy on pain perception and disability level in chronic non-specific low back pain. A randomized, single-blinded (the assessor collecting the outcome data was blinded), controlled trial. A private physiotherapy research clinic. A total of 64 individuals, 20 men and 44 women, mean (SD) age was 51 years (11.93), with low back pain of more than three months, with or without pain radiating to the lower extremities above the knee, were distributed into a control ( n = 20) or an experimental group ( n = 44). A 2:1 randomization ratio was used in favour of the latter. A transregional interferential current electrotherapy protocol was performed for participants in the experimental group, while the control group underwent a 'usual care' treatment (massage, mobilization and soft-tissue techniques). All subjects received up to 10 treatment sessions of 25 minutes over a two-week period, and completed the intervention and follow-up evaluations. Self-perceived pain was assessed with a Visual Analogue Scale. Secondary measure included the Oswestry Low Back Disability Index. Evaluations were collected at baseline and after the intervention protocol. Significant between-group differences were found for interferential current therapy on pain perception ( p = 0.032) and disability level ( p = 0.002). The observed differences in the between-group mean changes were of 11.34 mm (1.77/20.91) and 13.38 points (4.97/21.78), respectively. A two-week transregional interferential current treatment has shown significant short-term efficacy, when compared with a 'usual care' protocol, on self-perceived pain and functionality in subjects with chronic low back pain.

Three treatments for non-specific lumbar pain--balneotherapy, underwater traction bath, and underwater massage--were assessed in a randomised prospective controlled trial in 158 outpatients. Each group was treated for four weeks and patients were reviewed at the end of this period and at 12 months after entry to the trial. The prescription of analgesics and the pain score were significantly reduced in all three treated groups, but there was no difference between the three groups. No significant change occurred in spinal motion and the straight leg raising test. After one year only the analgesic consumption was significantly lower than in the control group. PMID:1535495

Interdependences between pain and anxiety in cardiac ischaemia are multidimensional and complex. Both of these phenomena share a lot of traits and they tend to reinforce each other at physiological level. Apart from arduousness of pain, cognitive understanding of its nature becomes an important mediating factor. One of important characteristics of the patient's attitude towards their illness is localization of pain control. The aim of the study was to analyze an interdependence between an anxiety as a state and as a trait and the localization of pain control in women with coronary heart decease. The study included 52 female patients hospitalised at The Department of Cardiology of The Medical University of Lublin who underwent coronarography. The used methods included an interview, State - Trait Anxiety Inventory of Spielberger (STAI) and The Beliefs about Pain Control Questionnaire (BPCQ). The results did not confirm an often suggested opinion that internal localization of pain control reduces anxiety and activates the patient. The intensity of the internal localization of pain control correlates significantly with the intensity of the dependence of pain of activity of the doctors as well as on the anxiety as trait. It is higher in women with lower education. Perhaps better educated patients, not so ready to react with anxiety, can treat pain more realistically as a sign of a pathological process which can be understood and evaluated not so much as a catastrophe. They do not feel personally responsible for the pain, either, and are able to accept the limits of the doctor's assistance, having no unrealistic expectations with regard to the pain treatment. The results of the research indicate that in women with ischiaemic heart decease better adjustment to the illness and a lower level of anxiety as a trait are connected with the understanding and acceptance of their situation by the patient, rather than with too big extent of expectations towards the control of pain

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.

Capsaicin specifically activates, and then gradually exhausts, the transient receptor potential vanilloid type 1 (TRPV1) receptor, a key receptor in neuropathic pain. Activation of the TRPV-1 receptor is accompanied by burning pain. A natural substance or medication that can reduce the burning pain resulting from capsaicin application may have therapeutic potential in neuropathic pain. To assess the pain-relieving effects of a mannitol-containing cream in a capsaicin-based pain model. Randomized, placebo-controlled, double-blind clinical trial. Outpatient pain clinic. Twenty-five adults with pain-free lips. Capsaicin .075% cream was applied to both halves of each participant's upper lip, inducing pain via stimulation of the transient receptor potential vanilloid 1 (TRPV1, capsaicin) receptor, then removed after 5 minutes or when participants reported a burning pain of 8/10, whichever came first. A cream containing mannitol and the same cream without mannitol (control) were then immediately applied, 1 on each side of the lip, in an allocation-masked manner. Participants self-recorded a numeric rating scale (NRS, 0-10) pain score for each side of the lip per minute for 10 minutes. A t-test was performed to evaluate the pain score change from baseline between each side of the lip at each recording. Area under the curve (AUC) analysis was used to determine the overall difference between groups. Participants reached a capsaicin-induced pain level of 7.8 ± 1.0 points in 3.3 ± 1.6 minutes that was equal on both sides of the lip. Both groups reported progressive diminution of pain over the 10-minute study period. However, participants reported significantly reduced pain scores on the mannitol cream half-lip compared to control at 3 through 10 minutes (P < .05) and in AUC analysis (P < .001). Mannitol cream reduced self-reported pain scores in a capsaicin pain model more rapidly than a control cream, potentially via a TRPV1 receptor effect. Copyright © 2015 American

Dental attrition models predicting temporomandibular joint disease or masticatory muscle pain versus asymptomatic controls.

To determine whether patients with temporomandibular joint disease or masticatory muscle pain can be usefully differentiated from asymptomatic controls using multifactorial classification tree models of attrition severity and/or rates. Measures of attrition severity and rates in patients diagnosed with disc displacement (n = 52), osteoarthrosis (n = 74), or masticatory muscle pain only (n = 43) were compared against those in asymptomatic controls (n = 132). Cross-validated classification tree models were tested for fit with sensitivity, specificity, accuracy and log likelihood accountability. The model for identifying asymptomatic controls only required the three measures of attrition severity (anterior, mediotrusive and laterotrusive posterior) to be differentiated from the patients with a 74.2 +/- 3.8% cross-validation accuracy. This compared with cross-validation accuracies of 69.7 +/- 3.7% for differentiating disc displacement using anterior and laterotrusive attrition severity, 68.7 +/- 3.9% for differentiating disc displacement using anterior and laterotrusive attrition rates, 70.9 +/- 3.3% for differentiating osteoarthrosis using anterior attrition severity and rates, 94.6 +/- 2.1% for differentiating myofascial pain using mediotrusive and laterotrusive attrition severity, and 92.0 +/- 2.1% for differentiating myofascial pain using mediotrusive and anterior attrition rates. The myofascial pain models exceeded the > or =75% sensitivity and > or =90% specificity thresholds recommended for diagnostic tests, and the asymptomatic control model approached these thresholds. Multifactorial models using attrition severity and rates may differentiate masticatory muscle pain patients from asymptomatic controls, and have some predictive value for differentiating intracapsular temporomandibular disorder patients as well.

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.

This study aimed to investigate the relationship between the history of low back pain and quality of lumbopelvic motor control in soccer players. Forty-three male elite soccer players (mean age, 18.2 ± 1.4 years) filled in questionnaires related to low back pain and attended a session to assess lumbopelvic motor control by means of five tests (the bent knee fall out test, the knee lift abdominal test, the sitting knee extension test, the waiter's bow and the transversus abdominis test). A physiotherapist, blinded to the medical history of the participants, scored (0 = failed, 1 = correct) the performance of the players for each of the tests resulting in a lumbopelvic motor control score ranging from 0 to 5. Forty-seven per cent of the soccer players reported a disabling low back pain episode lasting at least two consecutive days in the previous year. These players scored worse lumbopelvic motor control than players without a history of low back pain (lumbopelvic motor control score of 1.8 vs. 3.3, P < 0.01). The between-groups difference was particularly marked for the bent knee fall out test, the knee lift abdominal test and the transversus abdominis test (P < 0.01). In conclusion, most soccer players with a history of low back pain had an altered lumbopelvic motor control. Further research should examine whether lumbopelvic motor control is etiologically involved in low back pain episodes in soccer players.

Limited data exist concerning the unique pain characteristics of patients with non-cancer terminal diseases referred for inpatient hospice care. To define the unique pain characteristics of patients admitted to an acute inpatient hospice setting with end-stage dementia or chronic obstructive lung disease (or chronic obstructive pulmonary disease) and to compare them to patients with end-stage cancer. Retrospective patient chart review. Demographic, physiological, pain parameters, and medication utilization data were extracted. Associations between pain characteristics, medication utilization, and admission diagnoses were assessed. Analyses included descriptive statistics. In total, 146 patients admitted to an acute inpatient hospice between 1 April 2011 and 31 March 2012 with an underlying primary diagnosis of chronic obstructive pulmonary disease (n = 51), dementia (n = 48), or cancer (n = 47). Pain was highly prevalent in all diagnostic groups, with cancer patients experiencing more severe pain on admission. Cancer patients received a significantly higher cumulative opioid dose compared with dementia and chronic obstructive pulmonary disease patients. Pain control within 24 h of pain onset was achieved in less than half of all patient groups with chronic obstructive pulmonary disease patients the least likely to achieve pain control. Despite the fact that pain is the most common complaint at the end of life, pain management may be suboptimal for some primary diagnoses. Admission diagnosis is the strongest predictor of pain control. Patient with cancer achieve the best pain control, and chronic obstructive pulmonary disease patients are the least likely to have their pain adequately treated. © The Author(s) 2015.

Functional disability in patients with low back pain: the mediator role of suffering and beliefs about pain control in patients receiving physical and chiropractic treatment.

PubMed

Pereira, M Graça; Roios, Edite; Pereira, Marta

Low back pain is the leading cause of disability worldwide. There is evidence that depression, anxiety, and external locus of control are negative predictors of functional disability in low back patients. This study focused on the mediator role of suffering and beliefs about pain control in the relationship between psychological morbidity and functional disability in patients receiving physical therapy and chiropractic treatment for chronic low back pain. The sample included 213 patients receiving chiropractic treatment and 125 receiving physical therapy, who answered the following instruments: Beliefs about Pain Control Questionnaire; Inventory of Subjective Experiences of Suffering in Illness; Oswestry Low Back Pain Disability Questionnaire; and the Hospital Anxiety and Depression Scales. Suffering was a mediator in the relationship between depression and functional disability in both treatment groups. Only beliefs related to external chance events mediated the relationship between depression and functional disability in the physical therapy group, but not in the chiropratic teratment group. Intervention should focus on suffering regardless of the type of treatment and target beliefs about pain control, in patients receiving physical therapy treatment since they seem to play a key role in functional disability in patients with low back pain.

Many HIV/AIDS patients experience pain often due to advanced HIV/AIDS infection and side effects of treatment. In sub-Saharan Africa, pain management for people with HIV/AIDS is suboptimal. With survival extended as a direct consequence of improved access to antiretroviral therapy, the prevalence of HIV/AIDS related pain is increasing. As most care is provided at home, the management of pain requires patient and family involvement. Pain education is an important aspect in the management of pain in HIV/AIDS patients. Studies of the effectiveness of pain education interventions for people with HIV/AIDS have been conducted almost exclusively in western countries. A randomised controlled trial is being conducted at the HIV and palliative care clinics of two public hospitals in Malawi. To be eligible, patient participants must have a diagnosis of HIV/AIDS (stage III or IV). Carer participants must be the individual most involved in the patient's unpaid care. Eligible participants are randomised to either: (1) a 30-minute face-to-face educational intervention covering pain assessment and management, augmented by a leaflet and follow-up telephone call at two weeks; or (2) usual care. Those allocated to the usual care group receive the educational intervention after follow-up assessments have been conducted (wait-list control group). The primary outcome is pain severity measured by the Brief Pain Inventory. Secondary outcomes are pain interference, patient knowledge of pain management, patient quality of life, carer knowledge of pain management, caregiver motivation and carer quality of life. Follow-up assessments are conducted eight weeks after randomisation by palliative care nurses blind to allocation. This randomised controlled trial conducted in sub-Saharan Africa among people living with HIV/AIDS and their carers will assess whether a pain education intervention is effective in reducing pain and improving pain management, quality of life and carer motivation.

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.

Control of cancer pain by epidural infusion of morphine.

PubMed

Pain that cannot be controlled by traditional oral and parenteral methods in those patients with advanced cancer can be alleviated by spinal administration of narcotics. Epidural and intrathecal infusion with morphine causes analgesia by blocking spinal receptors without significant long-term central nervous, gastrointestinal, and genitourinary system effects. Of the total of 33 patients, epidural catheters inserted in 20 patients then connected by a subcutaneous tunnel to a continuous infusion system. Implanted pumps were used in each of these patients. Because of the cost and limitations of the implanted pumps, epidural catheters were connected, either directly or by subcutaneous reservoirs, to external ambulatory infusion pumps in the remaining 13 patients. Patient assessment by a linear analogue scale to measure pain levels determined that 23 of the 33 total patients (70%) had excellent or good relief of pain. The delivery of spinal administration of narcotics to treat intractable cancer pain in patients is safe. Most importantly, this method of delivery can be used in community hospitals, in outpatient settings, and in home health care programs.

Midurethral slings are commonly used to treat stress urinary incontinence. Pain control, however, may be a concern. Liposomal bupivacaine is a local anesthetic with slow release over 72 hours, demonstrated to lower pain scores and decrease narcotic use postoperatively. The purpose of this study was to examine the impact of liposomal bupivacaine on pain scores and narcotic consumption following retropubic midurethral sling placement. This randomized, placebo-controlled trial enrolled women undergoing retropubic midurethral sling procedures with or without concomitant anterior or urethrocele repair. Subjects were allocated to receive liposomal bupivacaine (intervention) or normal saline placebo injected into the trocar paths and vaginal incision at the conclusion of the procedure. At the time of drug administration, surgeons became unblinded, but did not collect outcome data. Participants remained blinded to treatment. Surgical procedures and perioperative care were standardized. The primary outcome was the visual analog scale pain score 4 hours after discharge home. Secondary outcomes included narcotic consumption, time to first bowel movement, and pain scores collected in the mornings and evenings until postoperative day 6. The morning pain item assessed "current level of pain"; the evening items queried "current level of pain," "most intense pain today," "average pain today with activity," and "average pain today with rest." Likert scales were used to measure satisfaction with pain control at 1- and 2-week postoperative intervals. Sample size calculation deemed 52 subjects per arm necessary to detect a mean difference of 10 mm on a 100-mm visual analog scale. To account for 10% drop out, 114 participants were needed. One hundred fourteen women were enrolled. After 5 exclusions, 109 cases were analyzed: 54 women received intervention, and 55 women received placebo. Mean participant age was 52 years, and mean body mass index was 30.4 kg/m 2 . Surgical and

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.

Does adherence monitoring reduce controlled substance abuse in chronic pain patients?

Opioids are used extensively for chronic pain management in the United States. The frequency of opioid use prior to presenting to interventional pain management settings and in interventional pain management settings has been shown to be above 90%. Given that controlled substance abuse and illicit drug use are prevalent phenomena, adherence monitoring of patients that are prescribed opioids is becoming common. Adherence monitoring is carried out by an appropriate history, periodic evaluation of appropriate intake of drugs, random drug testing, and pill counts. Crucial to adherence monitoring is an initial controlled substance agreement and repeated review of the terms of this agreement with on-going education. However, the effect of adherence monitoring on drug abuse is unclear. To identify controlled substance abuse through implementation of the terms of a controlled substance agreement, including periodic review and monitoring outside the organization. Prospective evaluation with historical controls. Five hundred consecutive patients receiving prescription controlled substances were followed in a prospective manner. The evaluation consisted of a chart review to monitor controlled substance intake, with special attention to drugs obtained from outside the organization. Data collection for this purpose included information from records, pharmacies, referring physicians, and all the physicians involved in the treatment of the patient. Results from 500 consecutive patients were evaluated. Controlled substance abuse was seen in 9% of patients; overall, 5% of patients were obtaining controlled substances from other physicians, and 4% from illegal sources. Adherence monitoring, including controlled substance agreements and various periodic measures of compliance was associated with a 50% reduction in opioid abuse.

Satisfactory pain control for women undergoing surgical abortion is important for patient comfort and satisfaction. Clinicians ought to be aware of the safety and efficacy of different pain control regimens. This document will focus on nonpharmacologic modalities to reduce pain and pharmacologic interventions up to the level of minimal sedation. For surgical abortion without intravenous medications, a multimodal approach to pain control may combine a dedicated emotional-support person, visual or auditory distraction, administration of local anesthesia to the cervix with buffered lidocaine and a preoperative nonsteroidal anti-inflammatory drug. Oral opioids do not decrease procedural pain. Oral anxiolytics decrease anxiety but not the experience of pain. Further research is needed on alternative options to control pain short of moderate or deep sedation. Copyright © 2018 Elsevier Inc. All rights reserved.

Directing attention away from pain is often used in children's pain treatment programs to control pain. However, empirical evidence concerning its effectiveness is inconclusive. We therefore sought to understand other influencing factors, including executive function and its role in the pain experience. This study investigates the role of executive functioning in the effectiveness of distraction. School children (n=164) completed executive functioning tasks (inhibition, switching, and working memory) and performed a cold-pressor task. One half of the children simultaneously performed a distracting tone-detection task; the other half did not. Results showed that participants in the distraction group were engaged in the distraction task and were reported to pay significantly less attention to pain than controls. Executive functioning influenced distraction task engagement. More specifically, participants with good inhibition and working memory abilities performed the distraction task better; participants with good switching abilities reported having paid more attention to the distraction task. Furthermore, distraction was found to be ineffective in reducing pain intensity and affect. Executive functioning did not influence the effectiveness of distraction. However, a relationship was found between executive functioning and pain affect, indicating that participants with good inhibition and working memory abilities experienced the cold-pressor task as less stressful and unpleasant. Our findings suggest that distraction as a process for managing pain is complex. While it appears that executive function may play a role in adult distraction, in this study it did not direct attention away from pain. It may instead be involved in the overall pain experience.

1993-07-01

Although high-frequency low-intensity transcutaneous electric nerve stimulation (TENS) has been extensively used to relieve low back pain, experimental studies of its effectiveness have yielded contradictory findings mainly due to methodological problems in pain evaluation and placebo control. In the present study, separate visual analog scales (VAS) were used to measure the sensory-discriminative and motivational-affective components of low back pain. Forty-two subjects were randomly assigned to 1 of 3 groups: TENS, placebo-TENS, and no treatment (control). In order to measure the short-term effect of TENS, VAS pain ratings were taken before and after each treatment session. Also, to measure long-term effects, patients rated their pain at home every 2 h throughout a 3-day period before and 1 week, 3 months and 6 months after the treatment sessions. In comparing the pain evaluations made immediately before and after each treatment session, TENS and placebo-TENS significantly reduced both the intensity and unpleasantness of chronic low back pain. TENS was significantly more efficient than placebo-TENS in reducing pain intensity but not pain unpleasantness. TENS also produced a significant additive effect over repetitive treatment sessions for pain intensity and relative pain unpleasantness. This additive effect was not found for placebo-TENS. When evaluated at home, pain intensity was significantly reduced more by TENS than placebo-TENS 1 week after the end of treatment, but not 3 months and 6 months later. At home evaluation of pain unpleasantness in the TENS group was never different from the placebo-TENS group.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

We recently reported that glycated albumin (GA) in patients with Cushing's syndrome is low. In the present study, we examined whether serum albumin (SA)-adjusted GA (SAaGA) is an adequate indicator of glycemic control in patients with Cushing's syndrome. We studied 26 patients with Cushing's syndrome (13 patients without diabetes and 13 patients with diabetes). Twenty six non-diabetic subjects and 26 patients with type 2 diabetes mellitus matched for age, sex and BMI were used as the controls. SAaGA was calculated using the regression formula between SA and GA in non-diabetic patients with Cushing's syndrome and non-diabetic subjects. SA showed a significant correlation with GA in non-diabetic patients with Cushing's syndrome and non-diabetic subjects. GA, but not SAaGA, in non-diabetic patients with Cushing's syndrome was significantly lower than that in the non-diabetic controls. Furthermore, the GA/HbA1c ratio, but not the SAaGA/HbA1c ratio, in diabetic patients with Cushing's syndrome was significantly lower than that in the diabetic controls. The measured GA in the patients with Cushing's syndrome was significantly lower than the estimated GA, but there was no difference between SAaGA and the estimated GA. The present findings suggest that SAaGA is an adequate indicator of the glycemic control in patients with Cushing's syndrome. Copyright © 2014 The Canadian Society of Clinical Chemists.

Low back pain (LBP) is common, impacts on the individual and society, and is a major health concern. Psychological consequences of LBP, such as depression, are significant barriers to recovery, but mechanisms for the development of depression are less well understood. One potential mechanism is the individual's health locus of control (HLoC), that is, perception of the level of control an individual has over their health. The objective of this study is to investigate the moderation effect of HLoC on the pain-depression-disability pathway in those with LBP. The design is a nested cross-sectional analysis of two existing cohorts of patients (n=637) who had previously consulted their primary care physician about LBP. Measures were taken of HLoC, pain intensity and interference, depression, disability, and bothersomeness. Structural Equation Modeling analysis was applied to two path models that examined the pain to depression to disability pathway moderated by the HLoC constructs of Internality and Externality, respectively. Critical ratio (CR) difference tests were applied to the coefficients using pairwise comparisons. The results show that both models had an acceptable model fit and pathways were significant. CR tests indicated a significant moderation effect, with stronger pathway coefficients for depression for those who report low Internality (β 0.48), compared to those with high Internality (β 0.28). No moderation effects were found within the Externality model. HLoC Internality significantly moderates the pain-depression pathway in those with LBP, meaning that those who have a low perception of control report greater levels of depression. HLoC may signify depression among people with LBP, and could potentially be a target for intervention.

Pain and Its Control in Reptiles.

Reptiles have the anatomic and physiologic structures needed to detect and perceive pain. Reptiles are capable of demonstrating painful behaviors. Most of the available literature indicates pure μ-opioid receptor agonists are best to provide analgesia in reptiles. Multimodal analgesia should be practiced with every reptile patient when pain is anticipated. Further research is needed using different pain models to evaluate analgesic efficacy across reptile orders. Copyright © 2017 Elsevier Inc. 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

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

[Purpose] The aim of this study was to investigate the effectiveness of yoga in the management of chronic neck pain. [Subjects and Methods] Five electronic databases were searched to identify randomized controlled trials (RCTs) of yoga intervention on chronic neck pain. The trials were published in the English language between January 1966 and December 2015. The Cochrane Risk of Bias Tool was used to assess the quality of the trials. [Results] Three trials were identified and included in this review. A critical appraisal was performed on the trials, and the result indicated a high risk of bias. A narrative description was processed because of the small number of RCTs. Neck pain intensity and functional disability were significantly lower in the yoga groups than in the control groups. [Conclusion] Evidence from the 3 randomly controlled trials shows that yoga may be beneficial for chronic neck pain. The low-quality result of the critical appraisal and the small number of trials suggest that high-quality RCTs are required to examine further the effects of yoga intervention on chronic neck pain relief.

The ability to control lumbar extensor force output is necessary for daily activities. However, it is unknown whether this ability is impaired in chronic low back pain patients. Similarly, it is unknown whether lumbar extensor force control is related to the disability levels of chronic low back pain patients. Thirty-three chronic low back pain and 20 healthy people performed lumbar extension force-matching task where they increased and decreased their force output to match a variable target force within 20%-50% maximal voluntary isometric contraction. Force control was quantified as the root-mean-square-error between participants' force output and target force across the entire, during the increasing and decreasing portions of the force curve. Within- and between-group differences in force-matching error and the relationship between back pain group's force-matching results and their Oswestry Disability Index scores were assessed using ANCOVA and linear regression respectively. Back pain group demonstrated more overall force-matching error (mean difference=1.60 [0.78, 2.43], P<0.01) and more force-matching error while increasing force output (mean difference=2.19 [1.01, 3.37], P<0.01) than control group. The back pain group demonstrated more force-matching error while increasing than decreasing force output (mean difference=1.74, P<0.001, 95%CI [0.87, 2.61]). A unit increase in force-matching error while decreasing force output is associated with a 47% increase in Oswestry score in back pain group (R 2 =0.19, P=0.006). Lumbar extensor muscle force control is compromised in chronic low back pain patients. Force-matching error predicts disability, confirming the validity of our force control protocol for chronic low back pain patients. Copyright © 2017 Elsevier Ltd. All rights reserved.

Local anesthetics are commonly administered into surgical sites as a part of multimodal pain control regimens. Liposomal bupivacaine is a novel formulation of bupivacaine designed for slow diffusion of a single dose of local anesthetic over a 72-hour period. While early results are promising in various settings, no studies have compared pain management regimens containing liposomal bupivacaine to traditional regimens in patients undergoing anterior cruciate ligament (ACL) reconstruction. To evaluate liposomal bupivacaine in comparison with 0.25% bupivacaine hydrochloride (HCl) for pain control after ACL reconstruction. Randomized controlled trial; Level of evidence, 1. A total of 32 adult patients undergoing primary ACL reconstruction with a soft tissue quadriceps tendon autograft between July 2014 and March 2015 were enrolled. All patients received a femoral nerve block immediately before surgery. Patients then received either a 40-mL suspension of 20 mL Exparel (1 vial of bupivacaine liposome injectable suspension) and 20 mL 0.9% injectable saline or 20 mL 0.5% bupivacaine HCl and 20 mL 0.9% injectable saline, which was administered into the graft harvest site and portal sites during surgery. Patients were given either a postoperative smartphone application or paper-based journal to record data for 1 week after ACL reconstruction. Of the 32 patients recruited, 29 patients were analyzed (90.6%). Two patients were lost to follow-up, and 1 was excluded because of a postoperative hematoma. There were no statistically significant differences in postoperative pain, medication use, pain location, recovery room time, or mobility between the 2 study groups. There were comparable outcomes with 0.25% bupivacaine HCl at a 200-fold lower cost than liposomal bupivacaine. This study does not support the widespread use of liposomal bupivacaine for pain control after ACL reconstruction in the setting of a femoral nerve block.

The German Society for the Study of Pain has formed an interdisciplinary committee to answer urgent ethical questions on the diagnosis and treatment of pain and to give an ethical orientation on the care of pain and palliative patients. The treatment of pain is a fundamental objective of medicine. Competent and adequate relief of pain in all stages of life is a basic characteristic of a humane medicine oriented to the quality and meaning of life for people. However, there are substantial deficits in all areas, especially in the knowledge of physicians and patients, in training and further education, diagnosis and therapy. Freedom from pain is a substantial element of quality of life. A central duty of all physicians is an adequate diagnosis and treatment of acute pain and thereby the prophylaxis of chronic pain. If pain persists over a longer period of time, it loses the warning function and becomes taken for granted. Alterations, disabilities and limitations of the physical, psychic and social levels are the consequences. For these patients an interdisciplinary approach is necessary by which various medical disciplines, psychologists and physiotherapists are involved and all collaborate on the diagnosis and therapy of pain. All patients have the right to sufficient and individually tailored treatment of pain. Special attention must be paid to vulnerable patient groups, such as newborns, children and adolescents, as well as aged and mentally retarded patients. For cancer patients pain relief of their tumor pain is totally in the forefront. Indications of "unbearable pain" must not lead to resignation or even be seen as an argument for legalization of "death on request". The nursing of terminally ill patients necessitates a special measure not only of clinical, but also ethical competence, communication and multiprofessional collaboration. The modern options for palliative care are real alternatives to demands for legalization of "death on request". Physician

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

Buprenorphine-naloxone therapy in pain management.

Buprenorphine-naloxone (bup/nal in 4:1 ratio; Suboxone; Reckitt Benckiser Pharmaceuticals Incorporation, Richmond, VA) is approved by the Food and Drug Administration for outpatient office-based addiction treatment. In the past few years, bup/nal has been increasingly prescribed off-label for chronic pain management. The current data suggest that bup/nal may provide pain relief in patients with chronic pain with opioid dependence or addiction. However, the unique pharmacological profile of bup/nal confers it to be a weak analgesic that is unlikely to provide adequate pain relief for patients without opioid dependence or addiction. Possible mechanisms of pain relief by bup/nal therapy in opioid-dependent patients with chronic pain may include reversal of opioid-induced hyperalgesia and improvement in opioid tolerance and addiction. Additional studies are needed to assess the implication of bup/nal therapy in clinical anesthesia and perioperative pain management.

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.

To compare postoperative pain control in patients treated surgically for ankle fractures who receive popliteal blocks with those who received general anesthesia alone. Institutional Review Board approved prospective randomized study. Metropolitan tertiary-care referral center. All patients being treated with open reduction internal fixation for ankle fractures who met inclusion criteria and consented to participate were enrolled. Patients were randomized to receive either general anesthesia (GETA) or intravenous sedation and popliteal block. Patients were assessed for duration of procedure, total time in the operating room, and postoperative pain at 2, 4, 8, 12, 24, and 48 hours after surgery using a visual analog scale. Fifty-one patients agreed to participate in the study. Twenty-five patients received popliteal block, while 26 patients received GETA. There were no anesthesia-related complications. At 2, 4, and 8 hours postoperatively, patients who underwent GETA demonstrated significantly higher pain. At 12 hours, there was no significant difference between the 2 groups with regard to pain control. However, by 24 hours, those who had received popliteal blocks had significantly higher pain with no difference by 48 hours. Popliteal block provides equivalent postoperative pain control to general anesthesia alone in patients undergoing operative fixation of ankle fractures. However, patients who receive popliteal blocks do experience a significant increase in pain between 12 and 24 hours. Recognition of this "rebound pain" with early narcotic administration may allow patients to have more effective postoperative pain control.

Objective People with chronic pain and depression have worse health outcomes than those with chronic pain alone. Little is known about the effectiveness of depression treatment for this population. We examined the effect of depression treatment on medical and social outcomes for individuals with chronic pain and depression Methods Propensity score weighted analyses using both waves (1997-1998 and 2000-2001) of the National Survey of Alcohol, Drug, and Mental Health Problems were used to examine the effect of (1) any depression treatment and (2) minimally adequate depression treatment on persistence of depression symptoms, depression severity, pain severity, overall health, mental health status, physical health status, social functioning, employment status, and number of work days missed. Analyses were limited to those who met CIDI-SF criteria for major depressive disorder, reported having at least one chronic pain condition, and completed both interviews (n=553). Results Receiving any depression treatment was associated with higher scores on the mental component summary of the MOS SF-12, indicating better mental health (difference = 2.65 points, p=0.002) and less interference of pain on work (OR=0.57, p=0.02). Among those receiving treatment, minimal adequacy of treatment was not significantly associated with better outcomes. Conclusions Depression treatment improves mental health and reduces the effects of pain on work among those with chronic pain and depression. Understanding the effect of depression treatment on outcomes for this population is important for employers, healthcare providers treating this population, and policymakers working in this Decade of Pain Control and Research to improve care for chronic pain sufferers.

Reduced postural control is thought to contribute to the development and persistence of chronic non-specific low back pain (CNLBP). It is therefore frequently assessed in affected patients and commonly reported as the average amount of postural sway while standing upright under a variety of sensory conditions. These averaged linear outcomes, such as mean centre of pressure (CP) displacement or mean CP surface areas, may not reflect the true postural status. Adding nonlinear outcomes and multi-segmental kinematic analysis has been reported to better reflect the complexity of postural control and may detect subtler postural differences. In this cross-sectional study, a combination of linear and nonlinear postural parameters were assessed in patients with CNLBP (n = 24, 24-75 years, 9 females) and compared to symptom-free controls (CG, n = 34, 22-67 years, 11 females). Primary outcome was postural control measured by variance of joint configurations (uncontrolled manifold index, UI), confidence ellipse surface areas (CEA) and approximate entropy (ApEn) of CP dispersion during the response phase of a perturbed postural control task on a swaying platform. Secondary outcomes were segment excursions and clinical outcome correlates for pain and function. Non-parametric tests for group comparison with P-adjustment for multiple comparisons were conducted. Principal component analysis was applied to identify patterns of segmental contribution in both groups. CNLBP and CG performed similarly with respect to the primary outcomes. Comparison of joint kinematics revealed significant differences of hip (P < .001) and neck (P < .025) angular excursion, representing medium to large group effects (r's = .36 - .51). Significant (P's < .05), but moderate correlations of ApEn (r = -.42) and UI (r = -.46) with the health-related outcomes were observed. These findings lend further support to the notion that averaged linear outcomes do not suffice to describe subtle postural differences in

Subcutaneous port needle insertions are painful and distressing for children with cancer. The interactive MEDiPORT robot has been programmed to implement psychological strategies to decrease pain and distress during this procedure. This study assessed the feasibility of a future MEDiPORT trial. The secondary aim was to determine the preliminary effectiveness of MEDiPORT in reducing child pain and distress during subcutaneous port accesses. This 5-month pilot randomized controlled trial used a web-based service to randomize 4- to 9-year-olds with cancer to the MEDiPORT cognitive-behavioral arm (robot using evidence-based cognitive-behavioral interventions) or active distraction arm (robot dancing and singing) while a nurse conducted a needle insertion. We assessed accrual and retention; technical difficulties; outcome measure completion by children, parents, and nurses; time taken to complete the study and clinical procedure; and child-, parent-, and nurse-rated acceptability. Descriptive analyses, with exploratory inferential testing of child pain and distress data, were used to address study aims. Forty children were randomized across study arms. Most (85%) eligible children participated and no children withdrew. Technical difficulties were more common in the cognitive-behavioral arm. Completion times for the study and needle insertion were acceptable and >96% of outcome measure items were completed. Overall, MEDiPORT and the study were acceptable to participants. There was no difference in pain between arms, but distress during the procedure was less pronounced in the active distraction arm. The MEDiPORT study appears feasible to implement as an adequately-powered effectiveness-assessing trial following modifications to the intervention and study protocol.

Background Self-monitoring of blood glucose empowers diabetes patients to effectively control their blood glucose (BG) levels. A potential barrier to frequent BG controls is lancing pain, intrinsically linked to pricking the finger several times a day. In this study, we compared different state-of-the-art lancing devices from leading manufacturers regarding lancing pain, and we intended to identify lancing devices that are less painful. Methods First, 165 subjects compared 6 different BG monitoring systems—consisting of a lancing device and a BG meter—at home for 36 days and at least 3 BG tests per day. Second, the subjects directly compared 6 different lancing devices—independent from a BG meter—in a laboratory setting. The test results were collected in questionnaires, and lancing pain was rated on a numerical rating scale. Results One hundred fifty-seven subjects were included in the analysis. Accu-Chek BG monitoring systems were significantly (p ≤ .006) preferred to competitor BG monitoring systems and were rated by >50% of the subjects as “less painful” than competitor BG monitoring systems. Accu-Chek lancing devices were significantly (p < .001) preferred to competitor lancing devices and were rated by >60% of the subjects as “less painful” than competitor lancing devices. Conclusions We found significant differences in lancing pain between lancing devices. Diabetes patients clearly preferred lancing devices that cause less lancing pain. In order to improve patient compliance with respect to an adequate glycemic control, the medical staff should preferentially prescribe lancing devices that cause less lancing pain. PMID:20144427

Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacologic treatment for pain relief. TENS has been used to treat a variety of painful conditions. This review updates the basic and clinical science regarding the use of TENS that has been published in the past 3 years (ie, 2005−2008). Basic science studies using animal models of inflammation show changes in the peripheral nervous system, as well as in the spinal cord and descending inhibitory pathways, in response to TENS. Translational studies show mechanisms to prevent analgesic tolerance to repeated application of TENS. This review also highlights data from recent randomized, placebo-controlled trials and current systematic reviews. Clinical trials suggest that adequate dosing, particularly intensity, is critical to obtaining pain relief with TENS. Thus, evidence continues to emerge from both basic science and clinical trials supporting the use of TENS for the treatment of a variety of painful conditions while identifying strategies to increase TENS effectiveness.

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

One of the problems for mothers in the post-cesarean section period is pain, which disturbs the early relationship between mothers and newborns; timely pain management prevents the side effects of pain, facilitates the recovery of patient, reduces the costs of treatment by minimizing or eliminating the mother's distress, and increases mother-infant interactions. The aim of this study was to determine the effect of hand and foot massage on post-cesarean section pain. This study is a randomized and controlled trial which was performed in Mustafa Khomeini Hospital, Elam, Iran, April 1 to July 30, 2011; it was carried out on 80 pregnant women who had an elective cesarean section and met inclusion criteria for study. The visual analog scale was used to determine the pain intensity before, immediately, and 90 minutes after conducting 5 minutes of foot and hand massage. Vital signs were measured and recorded. The pain intensity was found to be reduced after intervention compared with the intensity before the intervention (p < .001). Also, there was a significant difference between groups in terms of the pain intensity and requests for analgesic (p < .001). According to these findings, the foot and hand massage can be considered as a complementary method to reduce the pain of cesarean section effectively and to decrease the amount of medications and their side effects.

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.

(i) To examine patient lifting techniques used by nurses, and (ii) to evaluate an effectiveness of the Spine Care for Nurses programme in chronic nonspecific low back pain syndrome reduction and the execution of proper patient lifting techniques. Millions of nurses around the world suffer from occupational-related chronic nonspecific low back pain (chronic nonspecific low back pain syndrome). Generally, low back pain in nurses is a result of increased pressure on the spine and can be associated with improperly conducted patient lifting techniques. A randomised controlled trial was conducted among 137 nurses with chronic nonspecific low back pain syndrome. Participants were randomised into an experimental and control group (experimental group n = 67, control group n = 70). Nurses in the experimental group attended the Spine Care for Nurses programme for 3 months. The programme consisted of didactic education, spine-strengthening exercises and education on safe patient handling techniques. The control group only received a brief written lifestyle guidance. The Zebris WinSpine Triple Lumbar examination was used to analyse nurses' patient lifting techniques (horizontal and vertical lifting). The lumbar pain intensity was measured with a 0-100 visual analogue scale. The pre-intervention average chronic nonspecific low back pain syndrome intensity score on visual analogue scale decreased from 49.3 to the postintervention score of 7.5. The correct execution of vertical lifting techniques in the experimental group increased from 8.91%-97.01% (control group: 8.57% pre-intervention test and postintervention test 11.42%). The horizontal patient lifting technique pre-intervention increased from 10.44%-100% correct execution in the experimental group (control group: pre-intervention test 10.00% and postintervention test 11.42%). The Spine Care for Nurses programme significantly reduced chronic nonspecific low back pain syndrome and increased the number of properly executed

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). A severe pain interference with breathing/coughing (pain ranked ≥ 7

To evaluate the effects of peritoneal cold nebulization of ropivacaine on pain control after gynecologic laparoscopy. Evidence obtained from a properly designed, randomized, double-blind, placebo-controlled trial (Canadian Task Force classification I). Tertiary care center. One hundred thirty-five women with American Society of Anesthesiologists disease classified as ASA I-III who were scheduled to undergo operative laparoscopy. Patients were randomized to receive either nebulization of 30 mg ropivacaine before surgery (preoperative group), nebulization of 30 mg ropivacaine after surgery (postoperative group), instillation of 100 mg ropivacaine before surgery (instillation group), or instillation of saline solution (control group). Nebulization was performed using the Aeroneb Pro device. Pain scores, morphine consumption, and ambulation time were collected in the post-anesthesia care unit and at 4, 6, and 24 hours postoperatively. One hundred eighteen patients completed the study. Patients in the preoperative group reported lower pain Numeric Ranking Scale values compared with those in the control group (net difference 2 points; 95% confidence interval [CI], 0.3-3.1 at 4 hours, 1-3 at 6 hours, and 0.7-3 at 24 hours; p = .01) Patients in the preoperative group consumed significantly less morphine than did those in the control group (net difference 7 mg; 95% CI, 0.7-13; p = .02). More patients who received nebulization walked without assistance within 12 hours after awakening than did those in the instillation and control groups (net difference 15%; 95% CI, 6%-24%; p = .001). Cold nebulization of ropivacaine before surgery reduced postoperative pain and morphine consumption and was associated with earlier walking without assistance. Copyright © 2014 AAGL.

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

Pain originating from the female reproductive organs is a substantial clinical problem to treat. Experimental models may be a tool for the study of visceral pain mechanisms and hence provide information to aid in formulating new treatment strategies. The aim was to develop and evaluate the performance and safety of a model for nociceptive stimulation of the uterine cervix by balloon dilatation using impedance planimetry. Three consecutive (repeated) dilatations at 1 ml/min, an isovolumetric and a fast dilatation at 2 ml/min were performed. Pilot studies were conducted in vitro on hysterectomy specimens, followed by application of the model in 14 healthy females. Subjects indicated the quality of perception and pain during dilatations by verbal reports and the McGill Pain Questionnaire (MPQ), and the intensity by a continuous electronic visual analog scale. The pain location was marked on an anatomical map. The balloon cross-sectional area (CSA) was measured simultaneously. The experimental procedure was atraumatic. Pain was evoked in all subjects, with referral to the hypogastric and low back regions. The word descriptors on the MPQ and the areas of referred sensations were similar to that seen clinically in abortion, labor and menstrual pain. The pain intensity correlated with balloon CSA (r=0.9, P<0.001). No significant differences were found for the balloon volumes (4.2, 3.8 and 3.9 ml) or CSA (163, 122 and 123 mm(2)) to pain threshold (PT) for repeated dilatations, suggesting the reliability of the model. There was significant correlation between the balloon volume and CSA to reach the PT for single and repeated cervical dilatations. During isovolumetric distension, greater overall pain intensity was demonstrated for the prolonged as compared to the shorter duration cervical stimulation. In conclusion, this is the first human experimental pain model for dilatation of the uterine cervix, providing a safe, controlled, quantifiable stimulus that evoked reliable

The Food and Drug Administration (FDA), Substance Abuse and Mental Health Services Administration (SAMHSA), and the National Institute for Drug Abuse (NIDA) report that no sound scientific studies support the medicinal use of cannabis. Despite this lack of scientific validation, many patients routinely use “medical marijuana,” and in many cases this use is for pain related to nerve injury. We conducted a double-blinded, placebo-controlled, crossover study evaluating the analgesic efficacy of smoking cannabis for neuropathic pain. Thirty-eight patients with central and peripheral neuropathic pain underwent a standardized procedure for smoking either high-dose (7%), low-dose (3.5%), or placebo cannabis. In addition to the primary outcome of pain intensity, secondary outcome measures included evoked pain using heat-pain threshold, sensitivity to light touch, psychoactive side effects, and neuropsychological performance. A mixed linear model demonstrated an analgesic response to smoking cannabis. No effect on evoked pain was seen. Psychoactive effects were minimal and well-tolerated, with some acute cognitive effects, particularly with memory, at higher doses. PMID:18403272

To assess benefits of mindfulness meditation and cognitive behavioral therapy (CBT)-based intervention for opioid-treated chronic low back pain (CLBP). 26-week parallel-arm pilot randomized controlled trial (Intervention and Usual Care versus Usual Care alone). Outpatient. Adults with CLBP, prescribed ≥30 mg/day of morphine-equivalent dose (MED) for at least 3 months. The intervention comprised eight weekly group sessions (meditation and CLBP-specific CBT components) and 30 minutes/day, 6 days/week of at-home practice. Outcome measures were collected at baseline, 8, and 26 weeks: primary-pain severity (Brief Pain Inventory) and function/disability (Oswestry Disability Index); secondary-pain acceptance, opioid dose, pain sensitivity to thermal stimuli, and serum pain-sensitive biomarkers (Interferon-γ; Tumor Necrosis Factor-α; Interleukins 1ß and 6; C-reactive Protein). Thirty-five (21 experimental, 14 control) participants were enrolled and completed the study. They were 51.8 ± 9.7 years old, 80% female, with severe CLBP-related disability (66.7 ± 11.4), moderate pain severity (5.8 ± 1.4), and taking 148.3 ± 129.2 mg/day of MED. Results of the intention-to-treat analysis showed that, compared with controls, the meditation-CBT group reduced pain severity ratings during the study (P = 0.045), with between-group difference in score change reaching 1 point at 26 weeks (95% Confidence Interval: 0.2,1.9; Cohen's d = 0.86), and decreased pain sensitivity to thermal stimuli (P < 0.05), without adverse events. Exploratory analyses suggested a relationship between the extent of meditation practice and the magnitude of intervention benefits. Meditation-CBT intervention reduced pain severity and sensitivity to experimental thermal pain stimuli in patients with opioid-treated CLBP. © 2016 American Academy of Pain Medicine.

Manipulation and mobilisation are commonly used to treat neck pain. This is an update of a Cochrane review first published in 2003, and previously updated in 2010. To assess the effects of manipulation or mobilisation alone compared wiith those of an inactive control or another active treatment on pain, function, disability, patient satisfaction, quality of life and global perceived effect in adults experiencing neck pain with or without radicular symptoms and cervicogenic headache (CGH) at immediate- to long-term follow-up. 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).

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.

With the shifting age demographics of the U.S. population, more psychologists will be asked to provide clinical services to older adults. Given the high prevalence of persistent pain in aging, in many cases this will mean providing empirically supported interventions for pain and the interference it creates. The purpose of this review is to provide a broad overview of the scope and impact of persistent pain in older people and to discuss mechanisms by which persistent geriatric pain can lead to suffering and disability. We consider the unique context of pain in older adulthood and review differences between older and younger people in terms of pain perception, the social network, beliefs about pain, pain-related coping, and adherence to pain medication. Finally, we discuss special issues affecting pain management in older adults, including dementia, polypharmacy, and barriers to accessing adequate pain care. This review also highlights a need for greater provider training in pain management to meet the needs of a changing U.S. population. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Best Practices in Management of Postpartum Pain.

PubMed

Fahey, Jenifer O

Pain has been documented as a major concern for women in the postpartum period. Management of postpartum pain, however, is a relatively neglected area of clinical research. As a result, evidence to support interventions to alleviate the discomforts associated with childbirth is sparse. This paucity of research on postpartum pain management is particularly surprising given that in the United States alone nearly 4 million women give birth each year. Inadequate pain relief in the hours to months following childbirth can interfere with maternal-newborn bonding and feeding and, by impeding mobility, can increase the risk of postpartum complications. In addition, pain that is not adequately managed may increase the risk of chronic pain that lasts beyond the postpartum period. In this article, the more common causes of pain following childbirth are reviewed and recommendations for pain management based on available evidence are outlined. Considerations for pain management in lactating women and for hospital discharge are discussed.

Moradi, Saeed; Naghavi, Neda

2010-01-01

INTRODUCTION: Many patients suffer from mild, moderate or severe pain during or after root canal therapy. Theoretically, post-operative pain control can be achieved by using long-acting local anesthetics. The aim of this study was to evaluate the efficacy of a long acting anesthesia, bupivacaine, on preventing post-operative pain associated with endodontic treatment, and to compare it with lidocaine. MATERIALS AND METHODS: This study was a double blind and randomized clinical trial on 30 patients' anterior maxillary teeth. The patients were divided into two groups of fifteen. One group was administered lidocanine (2% with 1:100000 epinephrine) local anesthesia and the other group was given bupivacaine (0.5% without epinephrine). The pain in patients were compared using the visual analogue scale (VAS) at definite times i.e. before treatment, during treatment and 2,4,6,8,10,12,24,36 and 48 hours after operation. Data were analyzed using One-way ANOVA tests. RESULTS: Bupivacaine significantly decreased postoperative pain compared to lidocaine. Postoperative pain was directly related to preoperative pain. Women reported more pain, though significant difference in postoperative pain report was not found between different ages. CONCLUSION: In conclusion, a single dose of bupivacaine 0.5% used in infiltration anesthesia could be more effective in reduction or prevention of post-operative endodontic pain compared with lidocaine.

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

PubMed Central

2011-01-01

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.

2016-12-01

Applied mechanical vibration in pediatric and adult populations has been shown to be an effective analgesic for acute and chronic pain, including needle pain. Studies among the neonatal population are lacking. According to the Gate Control Theory, it is expected that applied mechanical vibration will have a summative effect with standard nonpharmacologic pain control strategies, reducing behavioral and physiologic pain responses to heel lancing. To determine the safety and efficacy of mechanical vibration for relief of heel lance pain among neonates. In this parallel design randomized controlled trial, eligible enrolled term or term-corrected neonates (n = 56) in a level IV neonatal intensive care unit were randomized to receive either sucrose and swaddling or sucrose, swaddling, and vibration for heel lance analgesia. Vibration was applied using a handheld battery-powered vibrator (Norco MiniVibrator, Hz = 92) to the lateral aspect of the lower leg along the sural dermatome throughout the heel lance procedure. Neonatal Pain, Agitation, and Sedation Scale (N-PASS) scores, heart rate, and oxygen saturations were collected at defined intervals surrounding heel lancing. Infants in the vibration group (n = 30) had significantly lower N-PASS scores and more stable heart rates during heel stick (P = .006, P = .037) and 2 minutes after heel lance (P = .002, P = .016) than those in the nonvibration group. There were no adverse behavioral or physiologic responses to applied vibration in the sample. Applied mechanical vibration is a safe and effective method for managing heel lance pain. This pilot study suggests that mechanical vibration warrants further exploration as a nonpharmacologic pain management tool among the neonatal population.

Although the etiology of complex regional pain syndrome type 1 (CRPS 1) is still debated, many arguments favor central maladaptive changes in pain processing as an important causative factor. To look for the suspected alterations, 10 patients with CRPS affecting the left hand were explored with functional magnetic resonance imaging during graded electrical painful stimulation of both hands subsequently and compared with healthy participants. Activation of the anterior insula, posterior cingulate cortex (PCC), and caudate nucleus was seen in patients during painful stimulation. Compared with controls, CRPS patients had stronger activation of the PCC during painful stimulation of the symptomatic hand. The comparison of insular/opercular activation between controls and patients with CRPS I during painful stimulation showed stronger (posterior) opercular activation in controls than in patients. Stronger PCC activation during painful stimulation may be interpreted as a correlate of motor inhibition during painful stimuli different from controls. Also, the decreased opercular activation in CRPS patients shows less sensory-discriminative processing of painful stimuli.These results show that changed cerebral pain processing in CRPS patients is less sensory-discriminative but more motor inhibition during painful stimuli. These changes are not limited to the diseased side but show generalized alterations of cerebral pain processing in chronic pain patients.

Role of the cannabinoid system in pain control and therapeutic implications for the management of acute and chronic pain episodes.

Cannabis extracts and synthetic cannabinoids are still widely considered illegal substances. Preclinical and clinical studies have suggested that they may result useful to treat diverse diseases, including those related with acute or chronic pain. The discovery of cannabinoid receptors, their endogenous ligands, and the machinery for the synthesis, transport, and degradation of these retrograde messengers, has equipped us with neurochemical tools for novel drug design. Agonist-activated cannabinoid receptors, modulate nociceptive thresholds, inhibit release of pro-inflammatory molecules, and display synergistic effects with other systems that influence analgesia, especially the endogenous opioid system. Cannabinoid receptor agonists have shown therapeutic value against inflammatory and neuropathic pains, conditions that are often refractory to therapy. Although the psychoactive effects of these substances have limited clinical progress to study cannabinoid actions in pain mechanisms, preclinical research is progressing rapidly. For example, CB(1)mediated suppression of mast cell activation responses, CB(2)-mediated indirect stimulation of opioid receptors located in primary afferent pathways, and the discovery of inhibitors for either the transporters or the enzymes degrading endocannabinoids, are recent findings that suggest new therapeutic approaches to avoid central nervous system side effects. In this review, we will examine promising indications of cannabinoid receptor agonists to alleviate acute and chronic pain episodes. Recently, Cannabis sativa extracts, containing known doses of tetrahydrocannabinol and cannabidiol, have granted approval in Canada for the relief of neuropathic pain in multiple sclerosis. Further double-blind placebo-controlled clinical trials are needed to evaluate the potential therapeutic effectiveness of various cannabinoid agonists-based medications for controlling different types of pain.

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.

Cold therapy used in the sports medicine settings has been found to be effective in reducing postoperative pain; however, there are limited studies that examine the effect of cold therapy on postoperative pain in patients with posterior lumbar spinal fusion. The purpose of this study was to determine the effects of cold on postoperative spine pain and add to the body of knowledge specific to practical application of cold therapy in the spine surgery setting. Researchers used a two-group randomized control design to evaluate the effects of local cold therapy on postoperative pain and analgesia use after lumbar spinal fusion surgery. The primary outcome was postoperative pain. Secondary outcomes included analgesia use and perceived benefit of cold therapy. The intervention (cold) group had a marginally greater reduction in mean Numerical Rating Scale score across all 12 pain checks (M ± SD = -1.1 ± 0.8 points reduction vs. -1.0 ± 0.8 points reduction, p = .589). On average, the intervention group used less morphine equivalents (M ± SD = 12.6 ± 31.5 vs. 23.7 ± 40.0) than the control group across pain checks seven to 12 (p = .042). This study provides additional evidence to support the use of cold therapy as an adjuvant pain management strategy to optimize pain control and reduce opioid consumption following spine fusion surgical procedures.

To evaluate if wearing unstable shoes reduces low back pain and disability in nurses. A randomized controlled trial. Hospitals and homecare. A total of 20 matched female registered nurses with low back pain. The mean (standard deviation) age was 31 years (5) for the control and 34 years (6) for the intervention group; height was 161 cm (5) and 165 cm (7), respectively. The intervention group received unstable shoes at Week 2 to wear for at least 36 h/week for a month. The Oswestry Low Back Pain Disability Questionnaire and a visual analogue pain scale. The mean (standard deviation) pain level was 6 (1) at baseline vs. 6 (2) at Week 6 for the control group, and 5 (1) vs. 1 (1) for the intervention group. The mean (standard deviation) disability level was 31% (9) at baseline vs. 28% (7) at Week 6 for the control, and 27% (12) vs. 13% (5) for the intervention group. There were no significant changes over time on pain or disability levels for the control group. The intervention group reported lower levels of pain on Weeks 4 (mean difference ⩾-1.4, p ⩽ 0.009) and 6 (mean difference ⩾-3.1, p < 0.001). Disability levels were also lower on Weeks 4 (mean difference = -4.5%, p NS) and 6 (mean difference = -14.1%, p = 0.020). Wearing unstable shoes reduced low back pain and disability in nurses and might be helpful as part of the back pain rehabilitation process. © The Author(s) 2015.

Objective: To determine patient experience of pain during treatment with fixed orthodontic appliances, expectations of pain during debond and whether biting on a soft acrylic wafer during debond decreases pain experience. Design: Multicentre randomized controlled trial. Setting: Three UK hospital based orthodontic departments: Mid-Staffordshire NHS Foundation Trust, Birmingham Dental Hospital and University Hospital of North Staffordshire. Materials and methods: Ninety patients were randomly allocated to either the control (n = 45) or wafer group (n = 45). A visual analogue scale-based questionnaire was completed pre-debond to determine pain experience during treatment and expectations of pain during debond. The appliances were debonded and those in the wafer group bit on a soft acrylic wafer. A second questionnaire was completed post-debond to assess the pain experienced. Results: Biting on an acrylic wafer significantly reduced the pain experienced when debonding the posterior teeth (P≤0·05). Thirty-nine per cent found the lower anterior teeth the most painful. The expected pain was significantly greater than that actually experienced (P≤0·0001). Greater pain during treatment correlated with increased expectations and increased actually experienced pain (P≤0·0001). Conclusions: Biting on a soft acrylic wafer during debond of the posterior teeth reduces the pain experienced. The lower anterior teeth are the most painful. The pain expected is significantly greater than actually experienced. Patients who had greater pain during treatment expected and experienced greater pain at debond. PMID:24009318

Pain in children, especially in infancy, is frequently underestimated. Surprisingly, in ancient times, writers were more aware of the existence of pain in infancy and the need for its relief than in 20th century. They rated pain perception as being higher in infancy than in childhood. The study by McGraw (1941), although badly designed, convinced the vast majority of clinicians that infants do not feel pain and do not require analgesia. This theory, reinforced by the fear of using opioids in young children, dominated medical thinking for more than 30 years. Later studies on pain perception in foetuses, and careful analysis of infants' reactions to blood sampling, helped doctors to understand the necessity of adequate analgesia in young children. In this review, we present the approach to pain in children over centuries, from ancient times to the latest developments in this field.

To study the clinical efficacy of sacral manual therapy in the treatment of coccygodynia. From November 2013 to July 2015, 184 patients with sacrococcygeal pain were divided into treatment group and control group. There were 26 males and 65 females in the treatment group, with an average age of (39.63±11.62) years old. In the control group, there were 31 males and 62 females, with an average age of (41.47±11.56) years old. The patients in the treatment group were treated with sacrococcygeal massage therapy, 3 times a week for 2 weeks. The patients in the control group were treated with Diclofenac Diethylamine Emulgel, 2 times a day for 2 weeks. The VAS pain score, score in rating scale of sacrococcygeal pain and degree of tenderness were obtained on the first day of treatment, 2, 7, 14 days and 3 months after treatment to evaluate clinical results. When comparing the VAS pain score of sacrococcygeal pain within the two groups, the differences began to reach statistical significance on the second day( P <0.001). The chagne of VAS pain scores, the change of scores in rating scale of sacrococcygeal pain and the degree of tenderness in the treatment group were all significontly larger that those in the contral group from the second day. The curative effect of sacral manipulation group is better than that of Diclofenac Diethylamine Emulgel group in the treatment of sacrococcygeal pain.

We evaluated the effectiveness of high-frequency transcutaneous electrical nerve stimulation (TENS) as a pain relief resource for primiparous puerpere who had experienced natural childbirth with an episiotomy. A controlled, randomized clinical study was conducted in a Brazilian maternity ward. Forty puerpere were randomly divided into two groups: TENS high frequency and a no treatment control group. Post-episiotomy pain was assessed in the resting and sitting positions and during ambulation. An 11-point numeric rating scale was performed in three separate evaluations (at the beginning of the study, after 60 min and after 120 min). The McGill pain questionnaire was employed at the beginning and 60 min later. TENS with 100 Hz frequency and 75 µs pulse for 60 min was employed without causing any pain. Four electrodes ware placed in parallel near the episiotomy site, in the area of the pudendal and genitofemoral nerves. An 11-point numeric rating scale and McGill pain questionnaire showed a significant statistical difference in pain reduction in the TENS group, while the control group showed no alteration in the level of discomfort. Hence, high-frequency TENS treatment significantly reduced pain intensity immediately after its use and 60 min later. TENS is a safe and viable non-pharmacological analgesic resource to be employed for pain relief post-episiotomy. The routine use of TENS post-episiotomy is recommended. © 2012 The Authors.

Prospective controlled intervention study. To evaluate a specific segmental muscle training program of the lumbar spine in order to prevent and reduce low back pain in young female teamgym gymnasts. Teamgym is a team sport comprising three events: trampette, tumbling and floor programme. In a recent study, it was found that teamgym gymnasts practice and compete despite suffering from back pain. Specific muscle control exercises of the lumbar spine have shown good results in reducing pain intensity and functional disability levels in patients with low back pain. To our knowledge, this type of training has not been studied in an adolescent athletic population before. Fifty-one gymnasts, with and without LBP, 11-16 years old, from three top-level gymnastics team participated in the study comprising 12 weeks. Every day the gymnasts answered a questionnaire regarding low back pain. After baseline (4 weeks) the intervention group performed a specific segmental muscle training program. Twenty-four gymnasts (47%) reported low back pain during baseline. Nine gymnasts failed to answer the questionnaire every day and the following results are based on 42 gymnasts (intervention group, n = 30, and control group, n=12). Gymnasts in the intervention group reported significantly less number of days with low back pain at completion compared to baseline (P=0.02). Gymnasts in the control group showed no difference in terms of days with low back pain or intensity of low back pain between baseline and completion. Eight gymnasts (out of 15) with LBP in the intervention group became pain free. Specific segmental muscle control exercises of the lumbar spine may be of value in preventing and reducing low back pain in young teamgym gymnasts.

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.

To evaluate whether inhaled nitrous oxide with oxygen (N 2 O/O 2 ) is associated with less pain compared to oral sedation for pain management during in-office hysteroscopic sterilization. This double blinded randomized controlled trial enrolled women undergoing in-office hysteroscopic sterilization. All participants received pre-procedure intramuscular ketorolac and a standardized paracervical block. The intervention group also received N 2 O/O 2 via a nasal mask titrated to a maximum 70%:30% mixture by a nurse during the procedure and placebo pills pre-procedure and the active control group received inhaled O 2 during the procedure and 5/325 mg hydrocodone/acetaminophen and 1 mg lorazepam pre-procedure. The primary outcome was maximum procedure pain on a 100 mm Visual Analog Scale (VAS with anchors at 0=no pain and 100=worst imaginable pain) assessed 3-5 min post procedure. Thirty women per treatment arm were required to detect a clinically significant pain difference of 20 mm. Seventy-two women, 36 per study arm, were randomized. Mean age of participants was 34.1±5.7 years and mean BMI was 30.1±6.6kg/m 2 . Mean maximum procedure pain scores were 22.8±27.6 mm and 54.5±32.7 mm for intervention and control groups, respectively (p<.001). Most study participants (97%) stated N 2 O/O 2 should be offered for gynecologic office procedures and 86% would pay for it if not a covered benefit. N 2 O/O 2 decreased pain with in-office hysteroscopic sterilization compared to oral sedation and is an effective pain management option for this procedure. Given its safety and favorable side effect profile, N 2 O/O 2 can be used for pain management for in-office hysteroscopic sterilization and adds a safe, easily administered option to currently available strategies.

Patients frequent take acetaminophen to treat dental pain. One previous study found a high rate of overuse of nonprescription analgesics in an emergency dental clinic. The purpose of this study is to determine if patients with dental pain are more likely to be treated for accidental acetaminophen poisoning than patients with other types of pain. We conducted a case-control study at 2 urban hospitals. Cases were identified by chart review of patients who required treatment for accidental acetaminophen poisoning. Controls were self-reported acetaminophen users taking therapeutic doses identified during a survey of emergency department patients. For our primary analysis, the reason for taking acetaminophen was categorized as dental pain or not dental pain. Our primary outcome was the odds ratio of accidental overdose to therapeutic users after adjustment for age, sex, alcoholism, and use of combination products using logistic regression. We identified 73 cases of accidental acetaminophen poisoning and 201 therapeutic users. Fourteen accidental overdose patients and 4 therapeutic users reported using acetaminophen for dental pain. The adjusted odds ratio for accidental overdose due to dental pain compared with other reasons for use was 12.8 (95% confidence interval, 4.2-47.6). We found that patients with dental pain are at increased risk to accidentally overdose on acetaminophen compared with patients taking acetaminophen for other reasons. Emergency physicians should carefully question patients with dental pain about overuse of analgesics. Copyright © 2011 Elsevier Inc. All rights reserved.

The autonomic nervous system (ANS) integrates afferent and motor activity for homeostatic processes including pain. The aim of the study was to compare hitherto poorly characterised relations between brainstem autonomic control and personality in response to visceral and somatic pain. Eighteen healthy subjects (16 females, mean age 34) had recordings during rest and pain of heart rate (HR), cardiac vagal tone (CVT), cardiac sensitivity to baroreflex (CSB), skin conductance level (SC), cardiac sympathetic index (CSI) and mean blood pressure (MBP). Visceral pain was induced by balloon distension in proximal (PB) and distal (DB) oesophagus and somatic pain by nail-bed pressure (NBP). Eight painful stimuli were delivered at each site and unpleasantness and intensity measured. Personality was profiled with the Big Five inventory. (1) Oesophageal intubation evoked "fight-flight" responses: HR and sympathetic (CSI, SC, MBP) elevation with parasympathetic (CVT) withdrawal (p<0.05). (2) Pain at all sites evoked novel parasympathetic/sympathetic co-activation with elevated HR but vasodepression (all p<0.05). (3) Personality traits correlated with slope of distal oesophageal pain-related CVT changes wherein more neurotic-introvert subjects had greater positive pain-related CVT slope change (neuroticism r 0.8, p<0.05; extroversion r -0.5, p<0.05). Pain-evoked heart rate increases were mediated by parasympathetic and sympathetic co-activation - a novel finding in humans but recently described in mammals too. Visceral pain-related parasympathetic change correlated with personality. ANS defence responses are nuanced and may relate to personality type for visceral pain. Clinical relevance of these findings warrants further exploration.

OBJECTIVE: In overhead sports such as volleyball, baseball, or tennis shoulder problems are very common. The aim of this study was to identify features which may correlate with shoulder problems in volleyball attackers. METHODS: 30 competitive volleyball attackers (mean age 25 years) were included in the study; 15 were suffering from shoulder pain and 15 had no history of shoulder pain. The results were compared with those of a control group of 15 recreational athletes without any overhead sports activities. RESULTS: Volleyball attackers have a different muscular and capsular pattern at the playing shoulder compared to the opposite shoulder. Their playing shoulder is depressed, the scapula lateralised, and the dorsal muscles and the posterior and inferior part of the shoulder capsule shortened. These differences were of more significance in volleyball attackers with shoulder pain than in volleyball players without shoulder pain. In contrast to recreational athletes without any overhead sports activity, there were no significant difference in the comparison of the two shoulders. The histories, clinical and sonographic findings did not reveal further typical features for volleyball attackers with shoulder pain. CONCLUSIONS: Muscular balance of the shoulder girdle is very important in this sport. It is therefore imperative to include adequate stretching and muscular training programme for the prevention, as well as for therapy, of shoulder pain in volleyball attackers.

Oxycodone is a useful analgesic for cancer patients in pain. However, its pharmacokinetics have not been sufficiently examined and there is a lack of information, with very few reports on pharmacokinetics concerning the absorption process in particular. With this in mind, we studied the pharmacokinetics of controlled-release oxycodone (Oxy contin). We measured its serum concentration in patients with cancer pain, and calculated parameters derived using the nonlinear least-squared method program (MULTI). In the result, pharmacokinetic parameters calculated at CL/F were: 45.6+/-22.0 L/hr (Mean+/-SD), Vd/F: 473.0+/-19 6.7 L, t(1/2): 7.2+/- 6.2 hr, kel: 0.103+/-0.034, kal: 1.082+/-0.604, Lag time: 0.9 9+/-0.40 hr. In addition, the serum oxycodone concentration hardly rose until 1 hour after and just before medication, whereupon a rapid increase was evident after 1 hour. The pharmacokinetics of controlled-release oxycodone in patients with cancer pain were clarified in this study. Especially during the absorption process, the lag time was calculated specifically at about 1 hour, making it approximately equal to MS contin.

Kinesiology taping (KT) is a rehabilitative technique performed by the cutaneous application of a special elastic tape. We tested the safety and efficacy of KT in reducing postoperative chest pain after lung lobectomy. One-hundred and seventeen consecutive patients, both genders, age 18-85, undergoing lobectomy for lung cancer between January 2013 and July 2015 were initially considered. Lobectomies were performed by the same surgical team, with thoracotomy or video-assisted thoracoscopic surgery (VATS) access. Exclusion criteria (n = 25 patients) were: previous KT exposure, recent trauma, pre-existing chest pain, lack of informed consent, >24-h postoperative intensive care unit treatment. After surgery, the 92 eligible patients were randomized to KT experimental group (n = 46) or placebo control group (n = 46). Standard postoperative analgesia was administered in both groups (paracetamol/non-steroidal anti-inflammatory drugs, epidural analgesia including opioids), with supplemental analgesia boluses at patient request. On postoperative day 1 in addition, in experimental group patients a specialized physiotherapist applied KT, with standardized tape length, tension and shape, over three defined skin areas: at the chest access site pain trigger point; over the ipsilateral deltoid/trapezius; lower anterior chest. In control group, usual dressing tape mimicking KT was applied over the same areas, as placebo. Thoracic pain severity score [visual analogue scale (VAS) ranging 0-10] was self-assessed by all patients on postoperative days 1, 2, 5, 8, 9 and 30. The KT group and the control group had similar demographics, lung cancer clinico-pathological features and thoracotomy/VATS ratio. Postoperatively, the two groups also resulted similar in supplemental analgesia, complication rate, mean duration of chest drainage and length of stay. There were no adverse events with KT application. After tape application, KT patients reported overall less thoracic pain than the

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

To evaluate pain control in chronic pancreatitis patients who underwent total pancreatectomy with islet cell transplantation or intrathecal narcotic pump infusion. We recognized 13 patients who underwent intrathecal narcotic pump (ITNP) infusion and 57 patients who underwent total pancreatectomy with autologous islet cell transplantation (TP + ICT) for chronic pancreatitis (CP) pain control between 1998 and 2008 at Indiana University Hospital. All patients had already failed multiple other modalities for pain control and the decision to proceed with either intervention was made at the discretion of the patients and their treating physicians. All patients were evaluated retrospectively using a questionnaire inquiring about their pain control (using a 0-10 pain scale), daily narcotic dose usage, and hospital admission days for pain control before each intervention and during their last follow-up. All 13 ITNP patients and 30 available TP + ICT patients were evaluated. The mean age was approximately 40 years in both groups. The median duration of pain before intervention was 6 years and 7 years in the ITNP and TP + ICT groups, respectively. The median pain score dropped from 8 to 2.5 (on a scale of 0-10) in both groups on their last follow up. The median daily dose of narcotics also decreased from 393 mg equivalent of morphine sulfate to 8 mg in the ITNP group and from 300 mg to 40 mg in the TP + ICT group. No patient had diabetes mellitus (DM) before either procedure whereas 85% of those who underwent pancreatectomy were insulin dependent on their last evaluation despite ICT. ITNP and TP + ICT are comparable for pain control in patients with CP however with high incidence of DM among those who underwent TP + ICT. Prospective comparative studies and longer follow up are needed to better define treatment outcomes.

Objective. To assess benefits of mindfulness meditation and cognitive behavioral therapy (CBT)-based intervention for opioid-treated chronic low back pain (CLBP). Design. 26-week parallel-arm pilot randomized controlled trial (Intervention and Usual Care versus Usual Care alone). Setting. Outpatient. Subjects. Adults with CLBP, prescribed ≥30 mg/day of morphine-equivalent dose (MED) for at least 3 months. Methods. The intervention comprised eight weekly group sessions (meditation and CLBP-specific CBT components) and 30 minutes/day, 6 days/week of at-home practice. Outcome measures were collected at baseline, 8, and 26 weeks: primary-pain severity (Brief Pain Inventory) and function/disability (Oswestry Disability Index); secondary-pain acceptance, opioid dose, pain sensitivity to thermal stimuli, and serum pain-sensitive biomarkers (Interferon-γ; Tumor Necrosis Factor-α; Interleukins 1ß and 6; C-reactive Protein). Results. Thirty-five (21 experimental, 14 control) participants were enrolled and completed the study. They were 51.8 ± 9.7 years old, 80% female, with severe CLBP-related disability (66.7 ± 11.4), moderate pain severity (5.8 ± 1.4), and taking 148.3 ± 129.2 mg/day of MED. Results of the intention-to-treat analysis showed that, compared with controls, the meditation-CBT group reduced pain severity ratings during the study (P = 0.045), with between-group difference in score change reaching 1 point at 26 weeks (95% Confidence Interval: 0.2,1.9; Cohen’s d = 0.86), and decreased pain sensitivity to thermal stimuli (P < 0.05), without adverse events. Exploratory analyses suggested a relationship between the extent of meditation practice and the magnitude of intervention benefits. Conclusions. Meditation-CBT intervention reduced pain severity and sensitivity to experimental thermal pain stimuli in patients with opioid-treated CLBP. PMID:26968850

A large subset of persons with migraine suffers from coexisting tension-type headache and neck pain which may adversely affect the prognosis of migraine. Aerobic exercise has been shown to decrease migraine burden in these persons. Therefore, the aim of this study was to investigate whether the effect of aerobic exercise in persons with migraine and coexisting tension-type headache and neck pain can be explained by changes in pain perception. Seventy consecutively recruited persons with migraine and coexisting tension-type headache and neck pain were randomized into exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 min, three times/week for 3 months. Controls continued their usual daily activities. Pericranial tenderness, pain thresholds, supra-thresholds and temporal summation were assessed at baseline, after treatment and at follow-up (6 months from baseline). Fifty-two persons with migraine and coexisting tension-type headache and neck pain completed the study. Aerobic exercise did not induce consistent changes in nociceptive pathways measured by pericranial tenderness, pressure pain thresholds and sensitivity to electrical stimulation. The effect of aerobic exercise cannot be explained by measurable effects on the pain modulation system. Thus, the positive effect on migraine burden may rather be explained by positive alteration of avoidance behaviour. Aerobic exercise can be recommended as a safe and inexpensive migraine treatment strategy. This study adds further knowledge about the positive effect of aerobic exercise for persons with migraine and coexisting tension-type headache and neck pain. This effect cannot be measured by changes in pain modulation, but may rather be explained by positive alteration of avoidance behaviour. © 2018 European Pain Federation - EFIC®.

Cognitive-behavioral therapy for clinical pain control: a 15-year update and its relationship to hypnosis.

Since Tan's (1982) review of cognitive and cognitive-behavioral methods for pain control was published 15 years ago, significant advances have been made in cognitive-behavioral therapy for pain. The scientific evidence for its efficacy for clinical pain attenuation is now much more substantial and is briefly reviewed. In particular, cognitive-behavioral therapy for chronic pain was recently listed as one of 25 empirically validated or supported psychological treatments available for various disorders. A number of emerging issues are further discussed in light of recent developments and research findings. The relationship of cognitive-behavioral therapy to hypnosis for pain control is briefly addressed, with suggestions for integrating hypnotic and cognitive-behavioral techniques.

Pain and pain tolerance in professional ballet dancers.

1995-01-01

Pain experience in sport had been the subject of increasing research in recent years. While sports professionals have generally been found to have higher pain thresholds than control subjects the reasons for this are not entirely clear. The present study seeks to investigate one possible explanatory factor, the importance of the popular image of the physical activity and of the self-image of its participants, by examining pain experience in professional ballet dancers. Like sports professionals, dancers were found to have higher pain and pain tolerance thresholds than age matched controls in the Cold Pressor Test. However, they also reported a more acute experience of the sensory aspects of the pain. Explanations of this apparent paradox are discussed both in terms of the neuroticism scores of the two groups and in terms of the dancers' greater experience of pain and its relationship with physical activity. The results illustrated the importance of using multidimensional measures of pain in this type of investigation. PMID:7788215

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. Further larger studies are required to confirm this finding. Australian and New Zealand Clinical Trials Registry (ACTRN12607000441415). Published by the BMJ Publishing Group Limited.

To determine the effects of a two-month intensive aquatic therapy programme on back pain, disability, quality of life, body composition and health-related fitness in sedentary adults with chronic low back pain. Controlled clinical trial. Community. Forty-nine sedentary patients with chronic low back pain. Patients were allocated into active group (n = 24, two months, five times/week) or waiting list, control group (n = 25) according to space on the programme. Outcomes variables were pain (visual analogue scale), disability (Oswestry Disability Index), quality of life (Quality Short-Form Health Survey 36), body composition (weight, body mass index, body fat percentage and skeletal muscle mass) and health-related fitness (sit-and-reach, handgrip strength, curl-up, Rockport 1-mile test). The active group significantly improved low back pain (-3.83 ± 0.35 mm on the visual analogue scale ), disability (-12.7 ± 1.3 points for the Oswestry Disability Index) and the standardized physical component (10.3 ± 1.4 points for the Quality Short-Form Health Survey 36) of quality-of-life domains (P < 0.001), with no significant changes on the standardized mental component (P = 0.114). In relation to body composition and fitness, the active group showed significant improvements (all P-values < 0.01). The control group presented no significant change in any parameter. A two-month intensive aquatic therapy programme of high-frequency (five times/week) decreases levels of back pain and disability, increases quality of life, and improves body composition and health-related fitness in sedentary adults with chronic low back pain.

To determine whether vibratory stimulation would decrease pain experienced by patients during corticosteroid injection for trigger finger. A total of 90 trigger finger injections were randomized to 1 of 3 cohorts. With the injection, patients received no vibration (control group), ultrasound vibration (sham control group), or vibration (experimental group). We used a commercial handheld massaging device to provide a vibratory stimulus for the experimental group. We obtained visual analog scale (VAS) pain scores before and after injection to assess anticipated pain and actual pain experienced. Anticipated pain and actual pain did not differ significantly among groups. Anticipated VAS pain scores were 45, 48, and 50 and actual VAS pain scores were 56, 56, and 63 for the vibration, control, and sham control groups, respectively. When normalized using anchoring VAS pain scores for "stubbing a toe" or "paper cut," no between-group differences remained in injection pain scores. Concomitant vibratory stimulation does not reduce pain experienced during corticosteroid injections for trigger finger. Therapeutic I. Copyright © 2014 American Society for Surgery of the Hand.

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.

Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p < 0.05). There were no between group differences in heat pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

Analgesia and hydration remain the only safe treatment for painful crises of sickle cell disease; hydroxyurea is effective, but the toxicity is still a problem. Piracetam is a nootropic drug that has reportedly been effective and non-toxic in sickle cell patients, but most studies were not placebo-controlled and included a small number of patients. The present study evaluated the drug in a double-blind crossed placebo-controlled clinical trial in 73 children and adolescents suffering from moderate to severe painful crises for 13 months. Information regarding frequency and severity of pain was acquired through monthly clinical evaluation, visits and house calls, and 4,300 weekly questionnaires filled out by the patients in their domiciles. A monthly pain score was calculated for each patient. Pain was the most frequent adverse manifestation of the disease stressing its significant bio-psycho-social impact. Although nearly all patients and relatives reported a better clinical course throughout the whole study, the drug was ineffective in the prevention of painful crises. This placebo effect may be ascribed to an unplanned and unsystematic 'cognitive-behavioural' management of the children. The pain score in the second semester of the study - both in the experimental and in the control groups - was significantly smaller than that in the first semester. In conclusion, piracetam was found to be ineffective in the prevention of painful crises; a powerful placebo effect due to adequate patient care was demonstrated. Copyright (c) 2005 S.

Tele-yoga for Chronic Pain: Current Status and Future Directions.

PubMed

Mathersul, Danielle C; Mahoney, Louise A; Bayley, Peter J

2018-01-01

Pain is a pervasive, debilitating disorder that is resistant to long-term pharmacological interventions. Although psychological therapies such as cognitive behavior therapy demonstrate moderate efficacy, many individuals continue to have ongoing difficulties following treatment. There is a current trend to establish complementary and integrative health interventions for chronic pain, for which yoga has been found to have exciting potential. Nevertheless, an important consideration within the field is accessibility to adequate care. Telehealth can be used to provide real-time interactive video conferencing leading to increased access to health care for individuals located remotely or who otherwise have difficulty accessing services, perhaps through issues of mobility or proximity of adequate services. This article assesses the current status and feasibility of implementing tele-yoga for chronic pain. Methodological limitations and recommendations for future research are discussed.

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.

Aim of investigation Hemicrania continua (HC) is an uncommon primary headache and little is known of the characteristics of such patients managed in an orofacial pain setting. This study provides clinical features of HC, its association with other disorders, and treatment outcomes of patients managed in the TMD and Orofacial Pain Clinic at the University of Minnesota. Methods A retrospective review of patient records was undertaken. Inclusion criteria were a diagnosis of HC and confirmation at follow-up. Results Six of the 1617 new patients seen between 2015 and 2017 met the selection criteria. Four patients presented with "facial pain", one with "toothache" and one with "jaw pain". All were female with mean age 55 ± 10.5 years (range = 41-69). Headache characteristics included unilateral (R:L = 1:1) pain of moderate intensity with severe exacerbations in the distribution of V 1 (1/6), V 1  + V 2 (3/6) and V 1  + V 2  + V 3 (2/6). Lacrimation and photophobia were the most common associated symptoms. Patient presentations were complicated by multiple medical and comorbid diagnoses. All were diagnosed with temporomandibular disorder (TMD). Indomethacin alone was sufficient for adequate headache control in 2/6 patients with several add-on medications providing sustained pain relief. Conclusions Comorbid pain conditions can be expected in patients with HC presenting to orofacial pain clinics. Symptom presentation varies, and multimodal treatment approach is necessary for success.
