Objective. The presence of altered nociceptive pain processing in patients with upper extremity tendinopathy/overuse injury is conflicting. Our aim was to compare pressure pain thresholds (PPTs) in symptomatic and distant pain-free areas between patients with upper extremity tendinopathy/overuse injury and controls. Methods. Five databases were searched from inception to October 15, 2020. The authors selected case-control studies comparing PPTs between individuals with upper extremity tendinopathy/overuse injury and pain-free controls. Data were extracted for population, diagnosis, sample size, outcome, and type of algometer. Results were extracted by 3 reviewers. The methodological quality/risk of bias (Newcastle-Ottawa Quality Assessment Scale) and evidence level (Grading of Recommendations Assessment, Development and Evaluation approach) were assessed. Meta-analyses of symptomatic, segment-related, and distant pain-free areas were compared. Results. The search identified 807 publications with 19 studies (6 shoulder, 13 elbow) eligible for inclusion. The methodological quality ranged from fair (48%) to good (37%). Patients exhibited lower bilateral PPTs than controls at the symptomatic area (affected side: MD = -175.89 kPa [95% CI = -220.30 to -131.48 kPa]; nonaffected side: MD = -104.50 kPa [95% CI = -142.72 to -66.28 kPa]) and the segment-related area (affected side: MD = -150.63 kPa [95% CI = -212.05 to -89.21 kPa]; nonaffected side: MD = -170.34 kPa [95% CI = - 248.43 to -92.25]) than controls. No significant differences in PPTs over distant pain-free areas were observed. Conclusion. Low to moderate quality evidence suggests bilateral hypersensitivity to pressure pain at the symptomatic and contralateral/mirror areas in patients with upper extremity tendinopathies/overuse injury. Moderate quality of evidence supports bilateral pressure pain sensitivity in the segment-related area (neck) in lateral epicondylalgia, but not in subacromial impingement syndrome. No evidence of widespread pressure pain hyperalgesia was reported. Impact. Early identification of people with altered pain modulation could guide clinicians in treatment strategies. This review shows that there is a complex interplay between peripheral and central pain mechanisms in upper extremity tendinopathies/overuse injuries and that there likely are different subgroups of patients with upper extremity conditions.

Objective. The purpose of this study was to evaluate the effects of trigger point (TrP) dry needling alone or as an adjunct to other interventions on pain intensity and related disability in nontraumatic shoulder pain. Methods. Ten databases were searched from inception to January 2020 for randomized clinical trials in which at least 1 group received TrP dry needling for shoulder pain of musculoskel et al origin with outcomes collected on pain intensity and related disability. Data extraction including participant and therapist details, interventions, blinding strategy, blinding assessment outcomes, and results were extracted by 2 reviewers. The risk of bias (Cochrane Risk of Bias, Cochrane Guidelines), methodological quality (Physiotherapy Evidence Database score), and evidence level (Grading of Recommendations Assessment, Development, and Evaluation approach) were assessed. The search identified 551 publications with 6 trials eligible for inclusion. Results. There was moderate-quality evidence that TrP dry needling reduces shoulder pain intensity with a small effect (mean difference = -0.49 points, 95% CI = -0.84 to -0.13; standardized mean difference = -0.25, 95% CI = -0.42 to -0.09) and low-quality evidence that TrP dry needling improves related disability with a large effect (mean difference = -9.99 points, 95% CI -15.97 to -4.01; standardized mean difference = -1.14, 95% CI -1.8 1 t o -0.47) compared with a comparison group. The effects on pain were only found at short term. The Cochrane Risk of Bias was generally low, but the heterogenicity of the results downgraded the evidence level. Conclusion. Moderate- to low-quality evidence suggests positive effects of TrP dry needling for pain intensity (small effect) and pain-related disability (large effect) in nontraumatic shoulder pain of musculoskel et al origin, mostly at short term. Future clinical trials investigating long-term effects are needed. Impact. Dry needling is commonly used for the management of musculoskel et al pain. This is the first meta-analysis to examine the effects of dry needling on nontraumatic shoulder pain. Keywords: Dry Needling, Shoulder Pain, Meta-Analysis, Introduction Shoulder pain represents a significant health problem showing a point prevalence from 7% to 26% and a lifetime prevalence around 67%; however, these data depend on the criteria used [...]

Objective. No study to our knowledge has investigated the effects longer than 1 year of manual therapy in carpal tunnel syndrome (CTS). The purpose of this study was to investigate the effects of manual therapy versus surgery at 4-year follow-up and to compare the post-study surgery rate in CTS. Methods. This randomized controlled trial was conducted in a tertiary public hospital and included 120 women with CTS who were randomly allocated to manual therapy or surgery. The participants received 3 sessions of physical therapy, including desensitization maneuvers of the central nervous system or carpal tunnel release combined with a tendon/nerve gliding exercise program at home. Primary outcome was pain intensity (mean and the worst pain). Secondary outcomes included functional status, symptom severity, and self-perceived improvement measured using a global rating of change scale. Outcomes for this analysis were assessed at baseline, 1 year, and 4 years. The rate of surgical intervention received by each group was assessed throughout the study. Results. At 4 years, 97 (81%) women completed the study. Between-group changes for all outcomes were not significantly different at 1 year (mean pain: mean difference [MD] = -0.3, 95% CI = -0.9 to 0.3; worst pain: MD = -1.2, 95% CI = -3.6 to 1.2; function: MD = -0.1, 95% CI = -0.4 to 0.2; symptom severity: MD = -0.1, 95% CI = -0.3 to 0.1) and 4 years (mean pain: MD = 0.1, 95% CI = -0.2 to 0.4; worst pain: MD = 0.2, 95% CI = -0.8 to 1.2; function: MD = 0.1, 95% CI = -0.1 to 0.3; symptom severity: MD = 0.2, 95% CI = -0.2 to 0.6). Self-perceived improvement was also similar in both groups. No between-group differences (15% physical therapy vs 13% surgery) in surgery rate were observed during the 4 years. Conclusions. In the long term, manual therapy, including desensitization maneuvers of the central nervous system, resulted in similar outcomes and similar surgery rates compared with surgery in women with CTS. Both interventions were combined with a tendon/nerve gliding exercise program at home. Impact. This is the first study to our knowledge to report clinical outcomes and surgical rates during a 4-year follow-up and will inform decisions regarding surgical versus conservative management of CTS. Lay summary. Women with CTS may receive similar benefit from a more conservative treatment--manual therapy--as they would from surgery., Carpal tunnel syndrome (CTS) is considered the most common entrapment neuropathy of the upper extremity. The estimated incidence of CTS in the United States has been reported to be 542 [...]

Background. Physical therapy and opioid prescriptions are common after hip surgery, but are sometimes delayed or not used. Objective. The objective of this study was to compare downstream health care utilization and opioid use following hip surgery for different patterns of physical therapy and prescription opioids. Design. The design of this study was an observational cohort. Methods. Health care utilization was abstracted from the Military Health System Data Repository for patients who were 18 to 50 years old and were undergoing arthroscopic hip surgery between 2004 and 2013. Patients were grouped into those receiving an isolated treatment (only opioids or only physical therapy) and those receiving both treatments on the basis of timing (opioid first or physical therapy first). Outcomes included overall health care visits and costs, hip-related visits and costs, additional surgeries, and opioid prescriptions. Results. Of 1870 total patients, 82.7% (n = 1546) received physical therapy only, 71.6% (n = 1339) received prescription opioids, and 1073 (56.1%) received both physical therapy and opioids. Because 24 patients received both opioids and physical therapy on the same day, they were eventually removed from the final timing-of-care analysis. Adjusted hip-related mean costs were the same in both groups receiving isolated treatments ($11,628 vs $11,579), but the group receiving only physical therapy had significantly lower overall total health care mean costs ($18,185 vs $23,842) and fewer patients requiring another hip surgery. For patients receiving both treatments, mean hip-related downstream costs were significantly higher in the group receiving opioids first than in the group receiving physical therapy first ($18,806 vs $16,955) and resulted in greater opioid use (7.83 vs 4.14 prescriptions), greater total days' supply of opioids (90.17 vs 44.30 days), and a higher percentage of patients with chronic opioid use (69-5% vs 53.2%). Limitations. Claims data were limited by the accuracy of coding, and observational data limit inferences of causality. Conclusions. Physical therapy first was associated with lower hip-related downstream costs and lower opioid use than opioids first; physical therapy instead of opioids was associated with less total downstream health care utilization. These results need to be validated in prospective controlled trials., Prognosis, the forecast of the likely course of a disease or condition, can be influenced by many different factors. One such factor is the timing of an interventions. In some [...]
