Electrotherapy modalities for adhesive capsulitis (frozen shoulder)

Effects of moderate physical activity on diabetic adhesive capsulitis: a randomized clinical trial

Background

Moderate physical activity (MPA) has proven advantages for glycemic control, cardiovascular health, and functional independence. However, physical activity is not part of routine conventional physical therapy (CPT) in managing diabetic adhesive capsulitis patients.

Objective

To determine the effects of moderate MPA on diabetic adhesive capsulitis (AC).

Methodology

A randomized control trial was conducted at the Combined Military Hospital (CMH), Muzaffarabad, Pakistan from March 2022 to October 2022. A total of n = 44 patients with diabetic AC, aged 40 to 65 years, HbA1c > 6.5% were enrolled. Group A received MPA and CPT, while Group B only received CPT for six weeks. The upper extremity function, pain, and range of motion were assessed at baseline, third week, and sixth week through the disability of arm, shoulder, and hand (DASH) questionnaire, numeric pain rating scale (NPRSS), and goniometer respectively.

Results

The NPRS score and ROMs showed significant improvement (p < 0.05) in group A compared to group B with a large effect size. When comparing the mean difference of the DASH score (73 + 7.21 vs. 57.9 + 12.64, p < 0.001, Cohen's d = 1.46) was significantly improved with large effect size in group A as compared to group B.

Conclusion

MPA along with CPT has positive effects on patient pain, range of motion, and disability in patients with diabetic adhesive capsulitis.

Rehabilitation in subjects with frozen shoulder: a survey of current (2023) clinical practice of Italian physiotherapists

OBJECTIVE

Frozen Shoulder (FS) is a musculoskeletal pathology that leads to disability, functional decline, and a worsening in quality of life. Physiotherapists are the primary professionals involved in the treatment of FS, and it is essential to determine if their practice aligns with evidence-based suggestions.

AIM

The aim is to assess the knowledge, skills, and operational strategies of Italian physiotherapists regarding FS and compare them with the existing literature.

METHODS

A web-based, anonymous, and voluntary cross-sectional survey was developed and administered to Italian physiotherapists to evaluate their clinical practices.

RESULTS

A total of 501 physiotherapists (38.5% female), completed the survey. More than half were under 35 years old (67.8%), declared working in private practice settings or being self-employed (57.1%), and were primarily engaged with musculoskeletal patients (81.8%). For subjects with FS at their first access, 21.4% identified X-rays as the most useful imaging technique to recognize pathologies beyond rehabilitation competence. In terms of general management, the majority reported working with an orthopaedic or physiatrist (47.5%) or in a multidisciplinary team (33.5%). Regarding manual therapy techniques, 63.3% of physiotherapists preferred intense degree mobilization, posterior direction, and moderate pain at the end of the range of motion for low irritable/high stiffness FS; however, there is a lack of consensus for managing very irritable/low stiffness FS. The majority of physiotherapists (57.7%) concurred that stretching improves the balance between metalloproteinase and its inhibitors. Additionally, 48.3% of physiotherapists selected mobile phone videos and messages to improve patients' compliance with exercises at home and for motivational/educational purposes.

DISCUSSION AND CONCLUSION

The clinical practices of Italian physiotherapists in FS subjects sometimes deviate from evidence-based recommendations. While some discrepancies may be attributed to the existing uncertainties in the literature regarding knowledge and management strategies for FS patients, the authors recommend a stronger adherence to evidence-based practice.

Manual therapy and exercise for lateral elbow pain

BACKGROUND

Manual therapy and prescribed exercises are often provided together or separately in contemporary clinical practice to treat people with lateral elbow pain.

OBJECTIVES

To assess the benefits and harms of manual therapy, prescribed exercises or both for adults with lateral elbow pain.

SEARCH METHODS

We searched the databases CENTRAL, MEDLINE and Embase, and trial registries until 31 January 2024, unrestricted by language or date of publication.

SELECTION CRITERIA

We included randomised or quasi-randomised trials. Participants were adults with lateral elbow pain. Interventions were manual therapy, prescribed exercises or both. Primary comparators were placebo or minimal or no intervention. We also included comparisons of manual therapy and prescribed exercises with either intervention alone, with or without glucocorticoid injection. Exclusions were trials testing a single application of an intervention or comparison of different types of manual therapy or prescribed exercises.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, extracted trial characteristics and numerical data, and assessed study risk of bias and certainty of evidence using GRADE. The main comparisons were manual therapy, prescribed exercises or both compared with placebo treatment, and with minimal or no intervention. Major outcomes were pain, disability, heath-related quality of life, participant-reported treatment success, participant withdrawals, adverse events and serious adverse events. The primary endpoint was end of intervention for pain, disability, health-related quality of life and participant-reported treatment success and final time point for adverse events and withdrawals.

MAIN RESULTS

Twenty-three trials (1612 participants) met our inclusion criteria (mean age ranged from 38 to 52 years, 47% female, 70% dominant arm affected). One trial (23 participants) compared manual therapy to placebo manual therapy, 12 trials (1124 participants) compared manual therapy, prescribed exercises or both to minimal or no intervention, six trials (228 participants) compared manual therapy and exercise to exercise alone, one trial (60 participants) compared the addition of manual therapy to prescribed exercises and glucocorticoid injection, and four trials (177 participants) assessed the addition of manual therapy, prescribed exercises or both to glucocorticoid injection. Twenty-one trials without placebo control were susceptible to performance and detection bias as participants were not blinded to the intervention. Other biases included selection (nine trials, 39%, including two quasi-randomised), attrition (eight trials, 35%) and selective reporting (15 trials, 65%) biases. We report the results of the main comparisons. Manual therapy versus placebo manual therapy Low-certainty evidence, based upon a single trial (23 participants) and downgraded due to indirectness and imprecision, indicates manual therapy may reduce pain and elbow disability at the end of two to three weeks of treatment. Mean pain at the end of treatment was 4.1 points with placebo (0 to 10 scale) and 2.0 points with manual therapy, MD -2.1 points (95% CI -4.2 to -0.1). Mean disability was 40 points with placebo (0 to 100 scale) and 15 points with manual therapy, MD -25 points (95% CI -43 to -7). There was no follow-up beyond the end of treatment to show if these effects were sustained, and no other major outcomes were reported. Manual therapy, prescribed exercises or both versus minimal intervention Low-certainty evidence indicates manual therapy, prescribed exercises or both may slightly reduce pain and disability at the end of treatment, but the effects were not sustained, and there may be little to no improvement in health-related quality of life or number of participants reporting treatment success. We downgraded the evidence due to increased risk of performance bias and detection bias across all the trials, and indirectness due to the multimodal nature of the interventions included in the trials. At four weeks to three months, mean pain was 5.10 points with minimal treatment and manual therapy, prescribed exercises or both reduced pain by a MD of -0.53 points (95% CI -0.92 to -0.14, I2 = 43%; 12 trials, 1023 participants). At four weeks to three months, mean disability was 63.8 points with minimal or no treatment and manual therapy, prescribed exercises or both reduced disability by a MD of -5.00 points (95% CI -9.22 to -0.77, I2 = 63%; 10 trials, 732 participants). At four weeks to three months, mean quality of life was 73.04 points with minimal treatment on a 0 to 100 scale and prescribed exercises reduced quality of life by a MD of -5.58 points (95% CI -10.29 to -0.99; 2 trials, 113 participants). Treatment success was reported by 42% of participants with minimal or no treatment and 57.1% of participants with manual therapy, prescribed exercises or both, RR 1.36 (95% CI 0.96 to 1.93, I2 = 73%; 6 trials, 770 participants). We are uncertain if manual therapy, prescribed exercises or both results in more withdrawals or adverse events. There were 83/566 participant withdrawals (147 per 1000) from the minimal or no intervention group, and 77/581 (126 per 1000) from the manual therapy, prescribed exercises or both groups, RR 0.86 (95% CI 0.66 to 1.12, I2 = 0%; 12 trials). Adverse events were mild and transient and included pain, bruising and gastrointestinal events, and no serious adverse events were reported. Adverse events were reported by 19/224 (85 per 1000) in the minimal treatment group and 70/233 (313 per 1000) in the manual therapy, prescribed exercises or both groups, RR 3.69 (95% CI 0.98 to 13.97, I2 = 72%; 6 trials).

AUTHORS' CONCLUSIONS

Low-certainty evidence from a single trial in people with lateral elbow pain indicates that, compared with placebo, manual therapy may provide a clinically worthwhile benefit in terms of pain and disability at the end of treatment, although the 95% confidence interval also includes both an important improvement and no improvement, and the longer-term outcomes are unknown. Low-certainty evidence from 12 trials indicates that manual therapy and exercise may slightly reduce pain and disability at the end of treatment, but this may not be clinically worthwhile and these benefits are not sustained. While pain after treatment was an adverse event from manual therapy, the number of events was too small to be certain.

Pharmacological interventions for early-stage frozen shoulder: a systematic review and network meta-analysis

OBJECTIVES

To evaluate the efficacy of pharmacological interventions for treating early-stage, pain predominant, adhesive capsulitis, also known as frozen shoulder.

METHODS

We performed a systematic review in accordance with PRSIMA guidelines. Searches were conducted on PUBMED, EMBASE and Cochrane Central Register of Controlled Trials on the 24th of February 2022. Outcomes were shoulder pain, shoulder function and range of movement. Synthesis involved both qualitative analysis for all studies and pairwise meta-analyses followed by a network meta-analysis for randomised controlled trials (RCTs).

RESULTS

A total of 3,252 articles were found, of which 31 met inclusion criteria, and 22 of these were RCTs. Intraarticular (IA) injection of corticosteroids (8 RCTS, 340 participants) and IA injection of platelet-rich plasma (PRP) (3 RCTs, 177 participants) showed benefit at 12 weeks compared with physical therapy in terms of shoulder pain and function, while oral non-steroidal anti-inflammatories (NSAIDs) (2 RCTs, 44 participants) and IA injection of hyaluronate (2 RCTs, 42 participants) did not show a benefit. Only IA PRP showed benefit over physical therapy for shoulder range of movement.

CONCLUSION

These results shows that IA corticosteroids IA PRP injections are beneficial for early-stage frozen shoulder. These findings should be appraised with care considering the risk of bias, heterogeneity, and inconsistency of the included studies. We believe that research focused on early interventions for frozen shoulder could improve patient outcomes and lead to cost-savings derived from avoiding long-term disability. Further well-designed studies comparing with standardised physical therapy or placebo are required to improve evidence to guide management.

Effectiveness of high-intensity laser therapy in the treatment of patients with frozen shoulder: a systematic review and meta-analysis

The purpose of this study is to evaluate the effects of high-intensity laser therapy (HILT) in patients with frozen shoulder. PRISMA guidelines were adhered to, and a systematic search was conducted in the PubMed, Web of Science, Scopus, CINAHL, Science Direct, and PEDro databases (last update: September 4, 2023; search period: December 2022-September 2023). The inclusion criteria encompassed RCTs comparing HILT with other physical therapy interventions in frozen patients with frozen shoulders, with or without sham HILT, assessing pain intensity, shoulder ROM, and disability outcomes. The quality of the RCTs was assessed with the Cochrane Risk of Bias tool, and evidence was assessed using the GRADE approach. Five trials met the eligibility criteria and were included in the review and meta-analysis, which pooled results from the visual analog scale (VAS), goniometry, and the shoulder pain and disability index (SPADI). Mean differences (MDs) for pain intensity and disability show a pooled effect in favor of HILT both for VAS (MD =  - 2.23 cm, 95% CI: - 3.25, - 1.22) and SPADI (MD =  - 10.1% (95% CI =  - 16.5, - 3.7), changes that are statistical (p < 0.01) and clinical. The MD for flexion (MD = 9.0°; 95% CI: - 2.36°, 20.3°; p = 0.12), abduction (MD = 3.4°; 95% CI: - 6.9°, 13.7°; p = 0.51), and external rotation (MD =  - 0.95°; 95% CI: - 5.36°, 3.5°; p = 0.67) does not show statistical and clinical differences between groups after treatment. PI and disability changes were graded as important due to their clinical and statistical results. HILT into a physical therapy plan reduce pain and disability, but it does not outperform conventional physical therapy in improving shoulder ROM. It is suggested that future RCTs compare the effects of HILT and LLLT to assess their possible differences in their analgesic effects.

Comparing Outcomes After Referral to Physical Therapy for Patients With Glenohumeral Osteoarthritis Based on the Radiographic Osteoarthritis Severity: A Retrospective Analysis

Introduction Glenohumeral osteoarthritis (GHOA) is a common cause of musculoskeletal pain (MSP) that can frequently lead to pain and functional disability in patients throughout the world. GHOA can be managed with conservative or surgical interventions, although conservative interventions, such as physical therapy (PT), are generally first-line interventions depending on the severity of GHOA. The purpose of this retrospective analysis was to examine how conventional PT impacts outcomes for patients with GHOA based on the severity of radiographic GHOA findings. Methods This study is a retrospective chart review of patients who were referred to PT for MSP and received PT in the outpatient setting between 2016 and 2022. Inclusion criteria were patients who received PT in the outpatient setting, received PT for MSP, had shoulder radiograph imaging within two years of initial PT evaluation, had more than one PT visit (i.e. attended a follow-up session after initial evaluation), and did not have a history of shoulder surgery. Primary outcome measures were pain, abduction active range-of-motion (AROM), and disability via the quick disabilities of the arm, shoulder, and hand (DASH). Patients were divided into the No GHOA group (n=104), Mild GHOA group (n=61), and Moderate/Severe GHOA group (n=55) based on the radiographic GHOA severity. Results All included patients (n=220) had a mean age of 62.2 ± 12.4 years old with a mean number of PT visits of 7.8 ± 4.5 visits. There was initially a significant difference in the magnitude of pain improvement between the three groups based on radiographic severity of GHOA (Kruskal-Wallis H=6.038; p=0.049); however, post hoc testing revealed no significant difference between any of the three groups for pain improvement (p=0.061 to p=1.000). There was also no significant difference in the magnitude of abduction AROM improvement between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=2.887; p=0.236). Finally, there was no significant difference in the magnitude of disability improvement via the Quick DASH between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=0.156; p=0.925). Conclusion Patients with GHOA referred to PT experience small but statistically significant short-term improvements in pain, abduction AROM, and disability regardless of GHOA radiographic severity. There is no significant association between the magnitude of clinical improvement and the severity of radiographic GHOA. However, despite statistically significant improvements in pain, only patients with mild GHOA experienced clinically significant improvements in pain. Patients with GHOA, regardless of severity, may or may not experience clinically significant improvements in disability after PT.

Photobiomodulation (Therapeutic Lasers): An Update and Review of Current Literature

Photobiomodulation therapy, also commonly known as laser therapy, continues to grow in popularity in veterinary medicine. It is the use of red and near-infrared light to simulate healing, relieve pain, and reduce inflammation. The potential variety of conditions for which it can be used as an adjunctive, non-invasive modality has propelled its use in both veterinary rehabilitation, sports medicine, and general practice. In the last decade, clinical research has grown with increasing evidence for efficacy for some conditions but mixed to limited in others and many conditions not represented.

What is the landscape of evidence about the safety of physical agents used in physical medicine and rehabilitation? A scoping review

BACKGROUND

Several systematic reviews (SRs) assessing the effectiveness of superficial physical agents have been published, but the evidence about their safety remains controversial.

OBJECTIVE

To identify areas where there is evidence of the safety of physical agents by a scoping review.

DESIGN

Four databases were systematically searched for including English SRs that explored and reported safety in terms of adverse events (AEs) related to the application of physical agents in outpatient and inpatient physical medicine and rehabilitation settings managed by healthcare professionals, published in January 2011-29 September 2021. The severity of AEs was classified according to the Common Terminology Criteria. Then, AE findings were summarised according to the SR syntheses. Finally, the reporting of the certainty of the evidence was mapped.

RESULTS

Overall, 117 SRs were retrieved. Most of the SRs included randomised controlled trials (77%) and patients with musculoskeletal disorders (67%). The most investigated physical agents were extracorporeal shock wave therapy (ESWT) (15%), transcutaneous electrical nerve stimulation (13%) and electrical stimulation (12%). No AE (35%) was reported in one-third of the included primary studies in SRs, whereas few severe AEs occurred in less than 1% of the sample. Among physical agents, ESWT showed an increased risk of experiencing mild AEs compared with the control. Most SRs reported a qualitative AE synthesis (65.8%), and few reported the certainty of the evidence (17.9%), which was mainly low.

CONCLUSION

We found evidence of safety on several physical agents coming mostly from qualitative synthesis. No significant harms of these interventions were found except for ESWT reporting mild AEs. More attention to the AEs reporting and their classification should be pursued to analyse them and assess the certainty of evidence quantitatively.

Anti-TNF (adalimumab) injection for the treatment of adults with frozen shoulder during the pain predominant stage protocol for a multi-centre, randomised, double blind, parallel group, feasibility trial

Objectives

The Anti-Freaze-F trial will assess the feasibility of conducting a large randomised controlled trial to assess whether intra-articular injection of anti-TNF (adalimumab) can reduce pain and improve function in people with pain predominant early stage frozen shoulder.

Methods and analysis

We are conducting a multi-centre, randomised feasibility study, with an embedded qualitative sub-study. We will recruit adults ≥18 years with a new episode of shoulder pain attributable to early stage frozen shoulder, recruited from at least five UK NHS musculoskeletal and related physiotherapy services. Participants (n=84) will be randomised (centralised computer generated 1:1 allocation) to receive either: 1) intra-articular injection of anti-TNF (adalimumab 160mg) or 2) placebo injection (saline [0.9% sodium chloride]), both under ultrasound guidance. A second injection of the allocated treatment (adalimumab 80mg) or equivalent volume of placebo will be administered 2-3 weeks later. All participants will receive a physiotherapy advice leaflet providing education and advice about frozen shoulder and pain management. The primary feasibility objectives are: 1) the ability to screen and identify potential participants with pain predominant early stage frozen shoulder; 2) willingness of eligible participants to consent and be randomised to intervention; 3) practicalities of delivering the intervention, including time to first injection and number of participants receiving second injection; 4) standard deviation of the Shoulder Pain and Disability Index (SPADI) score and attrition rate at 3 months (i.e. 12 weeks) post-randomisation in order to estimate the sample size for a definitive trial. We will also assess follow up rates and viability of patient-reported outcome measures and range of shoulder motion for a definitive trial. Research Ethics Committee approval (REC 21/NE/0214).

Effect of Pulsed Electromagnetic Fields (PEMFs) on Muscular Activation during Cycling: A Single-Blind Controlled Pilot Study

PURPOSE

PEMF stimulation results in a higher O₂ muscle supply during exercise through increased O₂ release and uptake. Given the importance of oxygen uptake in sport activity, especially in aerobic disciplines such as cycling, we sought to investigate the influence of PEMF on muscle activity when subjects cycled at an intensity between low and severe.

METHODS

Twenty semi-professional cyclists performed a constant-load exercise with randomized active (ON) or inactive (OFF) PEMF stimulation. Each subject started the recording session with 1 min of cycling without load (warm-up), followed by an instantaneous increase in power, as the individualized workload (constant-load physical effort). PEMF loops were applied on the vastus medialis and biceps femoris of the right leg. We recorded the electromyographic activity from each muscle and measured blood lactate prior the exercise and during the constant-load physical effort.

RESULTS

PEMF stimulation caused a significant increase in muscle activity in the warm-up condition when subjects cycled without load (p < 0.001). The blood lactate concentration was higher during PEMF stimulation (p < 0.001), a possible consequence of PEMF's influence on glycolytic metabolism.

CONCLUSION

PEMF stimulation augmented the activity and the metabolism of muscular fibers during the execution of physical exercise. PEMF stimulation could be used to raise the amplitude of muscular responses to physical activity, especially during low-intensity exercise.

Role of Platelet-Rich Plasma in the Treatment of Adhesive Capsulitis: A Prospective Cohort Study

Background

A glenohumeral (GH) joint disease, such as adhesive capsulitis, causes the shoulder capsule's fibrosis and adhesion to restrict mobility. Collagen and growth factors can be produced by platelet-rich plasma (PRP), which promotes stem cells and, as a result, improves the healing process. This study was done to determine the role of PRP injection in the treatment of adhesive capsulitis in terms of improvement in pain.

Methodology

This prospective cohort study was conducted at the Department of Orthopedics, Mayo Hospital, Lahore, Pakistan, from February 2022 to July 2022. A total of 305 patients were enrolled through the outpatient department. Basic demographic and clinical details, including the visual analog scale (VAS) pain score, were noted. First, 20 ml of the patient’s blood was drawn from the superficial saphenous vein by double syringe. After processing, the PRP was collected and injected in the subacromial bursa and intra-articular space adopting the anatomical approach. Then, the process was repeated at weekly intervals for four weeks. In this phase, PRP was injected only in the joint. The pain was assessed before and after six weeks of treatment and improvement in pain as per VAS was noted.

Results

In a total of 305 cases, the mean age was 60.47±11.55 years. There were 164 (53.8%) male and 141 (46.2%) female cases. The mean pain VAS scores before and after treatment were 6.56±1.79 and 2.42±1.71, respectively, and the mean reduction in pain after treatment was 64.57±19.40%. In 267 (87.5%) cases, an improvement of ≥ 50% was observed while 38 (12.5%) cases had an improvement of <50%.

Conclusion

The PRP can be used for the treatment of adhesive capsulitis to reduce pain. This non-operative method of treatment may help reduce the hospital burden of patients suffering from adhesive capsulitis.

Using TENS for Pain Control: Update on the State of the Evidence

Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological intervention used in the treatment of acute and chronic pain conditions. The first clinical studies on TENS were published over 50 years ago, when effective parameters of stimulation were unclear and clinical trial design was in its infancy. Over the last two decades, a better understanding of the mechanisms underlying TENS efficacy has led to the development of an adequate dose and has improved outcome measure utilization. The continued uncertainty about the clinical efficacy of TENS to alleviate pain, despite years of research, is related to the quality of the clinical trials included in systematic reviews. This summary of the evidence includes only trials with pain as the primary outcome. The outcomes will be rated as positive (+), negative (-), undecided (U), or equivalent to other effective interventions (=). In comparison with our 2014 review, there appears to be improvement in adverse events and parameter reporting. Importantly, stimulation intensity has been documented as critical to therapeutic success. Examinations of the outcomes beyond resting pain, analgesic tolerance, and identification of TENS responders remain less studied areas of research. This literature review supports the conclusion that TENS may have efficacy for a variety of acute and chronic pain conditions, although the magnitude of the effect remains uncertain due to the low quality of existing literature. In order to provide information to individuals with pain and to clinicians treating those with pain, we suggest that resources for research should target larger, high-quality clinical trials including an adequate TENS dose and adequate timing of the outcome and should monitor risks of bias. Systematic reviews and meta-analyses should focus only on areas with sufficiently strong clinical trials that will result in adequate sample size.

Frozen shoulder

Frozen shoulder is a common debilitating disorder characterized by shoulder pain and progressive loss of shoulder movement. Frozen shoulder is frequently associated with other systemic conditions or occurs following periods of immobilization, and has a protracted clinical course, which can be frustrating for patients as well as health-care professionals. Frozen shoulder is characterized by fibroproliferative tissue fibrosis, whereby fibroblasts, producing predominantly type I and type III collagen, transform into myofibroblasts (a smooth muscle phenotype), which is accompanied by inflammation, neoangiogenesis and neoinnervation, resulting in shoulder capsular fibrotic contractures and the associated clinical stiffness. Diagnosis is heavily based on physical examination and can be difficult depending on the stage of disease or if concomitant shoulder pathology is present. Management consists of physiotherapy, therapeutic modalities such as steroid injections, anti-inflammatory medications, hydrodilation and surgical interventions; however, their effectiveness remains unclear. Facilitating translational science should aid in development of novel therapies to improve outcomes among individuals with this debilitating condition.

Non-Surgical and Rehabilitative Interventions in Patients with Frozen Shoulder: Umbrella Review of Systematic Reviews

Background

Frozen shoulder (FS) is a painful condition characterized by progressive loss of shoulder function with passive and active range of motion reduction. To date, there is still no consensus regarding its rehabilitative treatment for pain management.

Purpose

The aim of this umbrella review of systematic reviews was to analyze the literature, investigating the effects of non-surgical and rehabilitative interventions in patients suffering from FS.

Patients and Methods

A review of the scientific literature was carried out from 2010 until April 2020 using the following search databases: PubMed, Medline, PEDro, Scopus and Cochrane Library of Systematic Reviews. A combination of terms was used for the search: frozen shoulder OR adhesive capsulitis AND systematic review OR meta-analysis AND rehabilitation NOT surgery NOT surgical intervention. We included systematic reviews that specifically dealt with adults with FS, treated with non-surgical approaches. All the systematic reviews and meta-analyses included in the study that met the inclusion criteria were assessed using the Assessment of Multiple Systematic Reviews as a quality assessment tool.

Results

Out of 49 studies, only 14 systematic reviews respected the eligibility criteria and were included in this study. Their results showed an important heterogeneity of the studies and all of them agree on the lack of high-quality scientific work to prove unequivocally which rehabilitative treatment is better than the other. Due to this lack of gold standard criteria, there may be also a heterogeneity in the diagnosis of the reviews analyzed.

Conclusion

Non-surgical and rehabilitative interventions are undoubtedly effective in treating FS, but there is no evidence that one approach is more effective than the other regarding the methods reported. Future high-quality RCTs are needed to standardize the treatment modalities of each physiotherapy intervention to provide strong recommendations in favor.

Factors related to initial treatment for adhesive capsulitis in the medicare population

BACKGROUND

Primary adhesive capsulitis (AC) is not well understood, and controversy remains about the most effective treatment approaches. Even less is known about the treatment of AC in the Medicare population. We aimed to fully characterize initial treatment for AC in terms of initial treatment utilization, timing of initial treatments and treatment combinations.

METHODS

Using United States Medicare claims from 2010-2012, we explored treatment utilization and patient characteristics associated with initial treatment for primary AC among 7,181 Medicare beneficiaries. Patients with primary AC were identified as patients seeking care for a new shoulder complaint in 2011, with the first visit related to shoulder referred to as the index date, an x-ray or MRI of the shoulder region, and two separate diagnoses of AC (ICD-9-CM codes: 726.00). The treatment period was defined as the 90 days immediately following the index shoulder visit. A multivariable logistic model was used to assess baseline patient factors associated with receiving surgery within the treatment period.

RESULTS

Ninety percent of beneficiaries with primary AC received treatment within 90 days of their index shoulder visit. Physical therapy (PT) alone (41%) and injection combined with PT (34%) were the most common treatment approaches. Similar patient profiles emerged across treatment groups, with higher proportions of racial minorities, socioeconomically disadvantaged and more frail patients favoring injections or watchful waiting. Black beneficiaries (OR = 0.37, [0.16, 0.86]) and those residing in the northeast (OR = 0.36, [0.18, 0.69]) had significantly lower odds of receiving surgery in the treatment period. Conversely, younger beneficiaries aged 66-69 years (OR = 6.75, [2.12, 21.52]) and 70-75 years (OR = 5.37, [1.67, 17.17]) and beneficiaries with type 2 diabetes had significantly higher odds of receiving surgery (OR = 1.41, [1.03, 1.92]).

CONCLUSIONS

Factors such as patient baseline health and socioeconomic characteristics appear to be important for physicians and Medicare beneficiaries making treatment decisions for primary AC.

Interventions for treating proximal humeral fractures in adults

BACKGROUND

Fractures of the proximal humerus, often termed shoulder fractures, are common injuries, especially in older people. The management of these fractures varies widely, including in the use of surgery. This is an update of a Cochrane Review first published in 2001 and last updated in 2015.

OBJECTIVES

To assess the effects (benefits and harms) of treatment and rehabilitation interventions for proximal humeral fractures in adults.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, trial registries, and bibliographies of trial reports and systematic reviews to September 2020. We updated this search in November 2021, but have not yet incorporated these results.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that compared non-pharmacological interventions for treating acute proximal humeral fractures in adults.  DATA COLLECTION AND ANALYSIS: Pairs of review authors independently selected studies, assessed risk of bias and extracted data. We pooled data where appropriate and used GRADE for assessing the certainty of evidence for each outcome. We prepared a brief economic commentary for one comparison.

MAIN RESULTS

We included 47 trials (3179 participants, mostly women and mainly aged 60 years or over) that tested one of 26 comparisons. Six comparisons were tested by 2 to 10 trials, the others by small single-centre trials only. Twelve studies evaluated non-surgical treatments, 10 compared surgical with non-surgical treatments, 23 compared two methods of surgery, and two tested timing of mobilisation after surgery. Most trials were at high risk of bias, due mainly to lack of blinding. We summarise the findings for four key comparisons below. Early (usually one week post injury) versus delayed (after three or more weeks) mobilisation for non-surgically-treated fractures Five trials (350 participants) made this comparison; however, the available data are very limited. Due to very low-certainty evidence from single trials, we are uncertain of the findings of better shoulder function at one year in the early mobilisation group, or the findings of little or no between-group difference in function at 3 or 24 months. Likewise, there is very low-certainty evidence of no important between-group difference in quality of life at one year. There was one reported death and five serious shoulder complications (1.9% of 259 participants), spread between the two groups, that would have required substantive treatment. Surgical versus non-surgical treatment Ten trials (717 participants) evaluated surgical intervention for displaced fractures (66% were three- or four-part fractures). There is high-certainty evidence of no clinically important difference between surgical and non-surgical treatment in patient-reported shoulder function at one year (standardised mean difference (SMD) 0.10, 95% confidence interval (CI) -0.07 to 0.27; 7 studies, 552 participants) and two years (SMD 0.06, 95% CI -0.13 to 0.25; 5 studies, 423 participants). There is moderate-certainty evidence of no clinically important between-group difference in patient-reported shoulder function at six months (SMD 0.17, 95% CI -0.04 to 0.38; 3 studies, 347 participants). There is high-certainty evidence of no clinically important between-group difference in quality of life at one year (EQ-5D (0: dead to 1: best quality): mean difference (MD) 0.01, 95% CI -0.02 to 0.04; 6 studies, 502 participants). There is low-certainty evidence of little between-group difference in mortality: one of the 31 deaths was explicitly linked with surgery (risk ratio (RR) 1.35, 95% CI 0.70 to 2.62; 8 studies, 646 participants). There is low-certainty evidence of a higher risk of additional surgery in the surgery group (RR 2.06, 95% CI 1.21 to 3.51; 9 studies, 667 participants). Based on an illustrative risk of 35 subsequent operations per 1000 non-surgically-treated patients, this indicates an extra 38 subsequent operations per 1000 surgically-treated patients (95% CI 8 to 94 more). Although there was low-certainty evidence of a higher overall risk of adverse events after surgery, the 95% CI also includes a slightly increased risk of adverse events after non-surgical treatment (RR 1.46, 95% CI 0.92 to 2.31; 3 studies, 391 participants). Open reduction and internal fixation with a locking plate versus a locking intramedullary nail Four trials (270 participants) evaluated surgical intervention for displaced fractures (63% were two-part fractures). There is low-certainty evidence of no clinically important between-group difference in shoulder function at one year (SMD 0.15, 95% CI -0.12 to 0.41; 4 studies, 227 participants), six months (Disability of the Arm, Shoulder, and Hand questionnaire (0 to 100: worst disability): MD -0.39, 95% CI -4.14 to 3.36; 3 studies, 174 participants), or two years (American Shoulder and Elbow Surgeons score (ASES) (0 to 100: best outcome): MD 3.06, 95% CI -0.05 to 6.17; 2 studies, 101 participants). There is very low-certainty evidence of no between-group difference in quality of life (1 study), and of little difference in adverse events (4 studies, 250 participants) and additional surgery (3 studies, 193 participants). Reverse total shoulder arthroplasty (RTSA) versus hemiarthroplasty There is very low-certainty evidence from two trials (161 participants with either three- or four-part fractures) of no or minimal between-group differences in self-reported shoulder function at one year (1 study) or at two to three years' follow-up (2 studies); or in quality of life at one year or at two or more years' follow-up (1 study). Function at six months was not reported. Of 10 deaths reported by one trial (99 participants), one appeared to be surgery-related. There is very low-certainty evidence of a lower risk of complications after RTSA (2 studies). Ten people (6.2% of 161 participants) had a reoperation; all eight cases in the hemiarthroplasty group received a RTSA (very low-certainty evidence).

AUTHORS' CONCLUSIONS

There is high- or moderate-certainty evidence that, compared with non-surgical treatment, surgery does not result in a better outcome at one and two years after injury for people with displaced proximal humeral fractures. It may increase the need for subsequent surgery. The evidence is absent or insufficient for people aged under 60 years, high-energy trauma, two-part tuberosity fractures or less common fractures, such as fracture dislocations and articular surface fractures. There is insufficient evidence from randomised trials to inform the choices between different non-surgical, surgical or rehabilitation interventions for these fractures.

A Positive Correlation between Steroid Injections and Cuff Tendon Tears: A Cohort Study Using a Clinical Database

This cohort study aimed to investigate the association between steroid injections for shoulder diseases and the increased incidence of cuff tendon tears. The Kaohsiung Veterans General Hospital clinical database was used in this study. Patients were enrolled using the corresponding diagnostic codes for shoulder diseases. Patients who received steroid injections were included in the case group, and those without steroid injections were included in the control group. The outcome measure was the occurrence of cuff tendon tears during the study period. Adjusted hazard ratios for outcomes were calculated using Cox regression analysis adjusted for sex, age, and comorbidities. Of the 1025 patients with shoulder disease, 205 were in the case group and 820 were in the control group. The incidence of cuff tendon tears was 9.8% in patients who received steroid injections (p < 0.001). The adjusted hazard ratios for steroid injections, smoking, and chronic liver disease were 7.44 (p < 0.001), 2.40 (p = 0.046), 3.25 (p = 0.007), respectively. Steroid injections on the shoulder were associated with a raised risk of cuff tendon tears by 7.44 times compared to non-injection. The incidence of cuff tendon tears increased by 3.25 times with concurrent chronic liver disease and by 2.4 times with smoking.

The Effectiveness of Ultrasound Deep Heat Therapy for Adhesive Capsulitis: A Systematic Review and Meta-Analysis

BACKGROUND

Adhesive capsulitis occurs with synovial inflammation and capsular fibrosis in the glenohumeral joint, leading to restriction of joint motion and pain. Heat therapy modalities, which aim at modifying dense collagenous tissues are commonly practiced interventions for patients with adhesive capsulitis; however, the effectiveness of ultrasound deep heat therapy (UST) on adhesive capsulitis is still unclear.

PURPOSE

This systematic review and meta-analysis study was conducted to evaluate the effects of UST on the improvement of pain and glenohumeral joint function in adhesive capsulitis compared to (1) no treatment or placebo, and (2) any other therapeutic modalities.

METHODS

A literature search was carried out in January 2021 in Cochrane Central Register of Controlled Trials, PubMed, EMBASE, PEDro, Web of Science, and Google Scholar. The main outcomes of interest were self-reported pain scores, disability scores, and the range of motion. This study was conducted based on the guidelines of the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) protocols, using random-effects models.

RESULTS

Seven studies were included in the systematic review with five studies forming the basis for meta-analyses. The effects of UST in patients with adhesive capsulitis were compared with placebo, shockwave therapy, corticosteroid injection, platelet-rich plasma injection, or cryotherapy. The results indicated that UST significantly improved pain scores when performed together with exercise and/or other physical modalities compared to placebo; however, whether UST provides benefits for the improvement of disability and/or the range of motion was uncertain in the present results.

CONCLUSIONS

The present findings suggest that UST as a co-intervention combined with other physical modalities is an effective means of improving the overall pain in patients with adhesive capsulitis.

Surgical versus Nonsurgical Multimodality Treatment in an Idiopathic Frozen Shoulder: A Retrospective Study of Clinical and Functional Outcomes

This retrospective study compared the clinical and functional outcomes of patients diagnosed with an idiopathic frozen shoulder with symptom onset of a maximum of six months, treated by arthroscopic capsular release followed by corticosteroid injection and physiotherapy to patients who received only corticosteroid injection followed by physiotherapy. The patients who underwent arthroscopic capsular release, intraoperative corticosteroid injection, and physiotherapy (Group I, n = 30) or received only corticosteroids injection and physiotherapy (Group II, n = 29) were examined in terms of shoulder range of motion (ROM), pain intensity, and function before a given treatment and three, six, and twelve months later. The groups were comparable pre-treatment in terms of ROM, pain, and functional outcome. Group I had statistically and clinically significantly better ROM and function at three and six months post-treatment than Group II. Despite being statistically significant, the between-group differences at twelve-month follow-up in ROM and function were too small to be considered clinically notable. The between-group comparison of pain revealed no significant differences at any post-treatment point of time. The early arthroscopic capsular release preceding corticosteroid injection and physiotherapy seemed more effective at three- and six-month follow-up; however, it brought a comparable result to corticosteroid injection and subsequent physiotherapy at twelve months follow-up.

A Targeted Approach to Post-Mastectomy Pain and Persistent Pain following Breast Cancer Treatment

Persistent pain following treatment for breast cancer is common and often imprecisely labeled as post-mastectomy pain syndrome (PMPS). PMPS is a disorder with multiple potential underlying causes including intercostobrachial nerve injury, intercostal neuromas, phantom breast pain, and pectoralis minor syndrome. Adding further complexity to the issue are various musculoskeletal pain syndromes including cervical radiculopathy, shoulder impingement syndrome, frozen shoulder, and myofascial pain that may occur concurrently and at times overlap with PMPS. These overlapping pain syndromes may be difficult to separate from one another, but precise diagnosis is essential, as treatment for each pain generator may be distinct. The purpose of this review is to clearly outline different pain sources based on anatomic location that commonly occur following treatment for breast cancer, and to provide tailored and evidence-based recommendations for the evaluation and treatment of each disorder.

Does TENS Reduce the Intensity of Acute and Chronic Pain? A Comprehensive Appraisal of the Characteristics and Outcomes of 169 Reviews and 49 Meta-Analyses

Background and Objectives: Uncertainty about the clinical efficacy of transcutaneous electric nerve stimulation (TENS) to alleviate pain spans half a century. There has been no attempt to synthesise the entire body of systematic review evidence. The aim of this comprehensive review was to critically appraise the characteristics and outcomes of systematic reviews evaluating the clinical efficacy of TENS for any type of acute and chronic pain in adults. Materials and Methods: We searched electronic databases for full reports of systematic reviews of studies, overviews of systematic reviews, and hybrid reviews that evaluated the efficacy of TENS for any type of clinical pain in adults. We screened reports against eligibility criteria and extracted data related to the characteristics and outcomes of the review, including effect size estimates. We conducted a descriptive analysis of extracted data. Results: We included 169 reviews consisting of eight overviews, seven hybrid reviews and 154 systematic reviews with 49 meta-analyses. A tally of authors' conclusions found a tendency toward benefits from TENS in 69/169 reviews, no benefits in 13/169 reviews, and inconclusive evidence in 87/169 reviews. Only three meta-analyses pooled sufficient data to have confidence in the effect size estimate (i.e., pooled analysis of >500 events). Lower pain intensity was found during TENS compared with control for chronic musculoskeletal pain and labour pain, and lower analgesic consumption was found post-surgery during TENS. The appraisal revealed repeated shortcomings in RCTs that have hindered confident judgements about efficacy, resulting in stagnation of evidence. Conclusions: Our appraisal reveals examples of meta-analyses with 'sufficient data' demonstrating benefit. There were no examples of meta-analyses with 'sufficient data' demonstrating no benefit. Therefore, we recommend that TENS should be considered as a treatment option. The considerable quantity of reviews with 'insufficient data' and meaningless findings have clouded the issue of efficacy. We offer solutions to these issues going forward.

Shoulder transcutaneous electric nerve stimulation decreases heart rate via potentiating vagal tone

By enhancing vagal activity, auricle transcutaneous electric nerve stimulation (TENS) is developed as a non-invasive therapy for heart failure. Nevertheless, though shoulder TENS used for treating adhesive capsulitis could affect vagal tone, its potential impact on heart functions remains unclear. In this study, electrocardiogram (ECG) and heart rate (HR) of subjects in response to sham, right-sided, or left-sided shoulder TENS (TENS-S, TENS-R, and TENS-L, respectively; 5 min) were recorded and analyzed. During the stimulation period, TENS-R constantly and TENS-L transiently decreased the HR of subjects; both TENS-R and TENS-L increased powers of the low- and high-frequency spectra. While TENS-R exhibiting no effect, TENS-L increased the ratio of low/high-frequency power spectrum indicating TENS-R decreased the HR through potentiating cardiac vagal tone. Collectively, these results suggest TENS could be an early and non-invasive therapy for heart failure patients before considering implant devices or devices are not feasible; moreover, therapists/physicians need to carefully monitor the potential adverse events during treatment for patient safety.

Trial registration: The study protocol was registered in ClinicalTrials.gov (NCT03982472; 11/06/2019).

Image-guided glucocorticoid injection versus injection without image guidance for shoulder pain

BACKGROUND

Despite widespread use, our 2012 Cochrane review did not confirm that use of imaging to guide glucocorticoid injection for people with shoulder pain improves its efficacy.

OBJECTIVES

To update our review and assess the benefits and harms of image-guided glucocorticoid injection compared to non-image-guided injection for patients with shoulder pain.

SEARCH METHODS

We updated the search of the Cochrane Central Register of Controlled Trials (CENTRAL, via Ovid), MEDLINE (Ovid), Embase (Ovid) and clinicaltrials.gov to 15 Feb 2021, and the World Health Organisation International Clinical Trials Registry Platform (http://www.who.int/trialsearch/Default.aspx) to 06 July 2020. We also screened reference lists of retrieved review articles and trials to identify potentially relevant studies.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials that compared image-guided glucocorticoid injection to injection without image guidance (either landmark-guided or intramuscular) injection in patients with shoulder pain (rotator cuff disease, adhesive capsulitis or mixed or undefined shoulder pain). Major outcomes were pain, function, proportion of participants with treatment success, quality of life, adverse events, serious adverse events and withdrawals due to adverse events. Minor outcomes were shoulder range of motion and proportion of participants requiring surgery or additional injections. There were no restrictions on language or date of publication.

DATA COLLECTION AND ANALYSIS

We used standard methodologic procedures expected by Cochrane.

MAIN RESULTS

Nineteen trials were included (1035 participants). Fourteen trials included participants with rotator cuff disease, four with adhesive capsulitis, and one with mixed or undefined shoulder pain. Trial size varied from 28 to 256 participants, most participants were female, mean age ranged between 31 and 60 years, and mean symptom duration varied from 2 to 23 months. Two trials were at low risk of bias for all criteria. The most notable sources of bias in the remaining trials included performance bias and detection bias. Moderate-certainty evidence (downgraded for bias) indicates that ultrasound-guided injection probably provides little or no clinically important benefits compared with injection without guidance with respect to pain (15 trials) or function (14 trials) at three to six weeks follow-up. It may not improve quality of life (2 trials, low-certainty evidence, downgraded due to potential for bias and imprecision) and we are uncertain about the effect of ultrasound-guided injection on participant-rated treatment success due to very low-certainty evidence (downgraded for bias, inconsistency and imprecision). Mean pain (scale range 0 to 10, higher scores indicate more pain) was 3.1 points with injection without image guidance and 0.5 points better (0.2 points better to 0.8 points better; 1003 participants, 15 trials) with an ultrasound-guided injection. This represents a slight difference for pain (0.5 to 1.0 points on a 0 to 10 scale). Mean function (scale range 0 to 100, higher scores indicate better function) was 68 points with injection without image guidance and 2.4 points better (0.2 points worse to 5.1 points better; 895 participants, 14 trials) with an ultrasound-guided injection. Mean quality of life (scale range 0 to 100, higher scores indicate better quality of life) was 65 with injection without image guidance and 2.8 points better (0.7 worse to 6.4 better; 220 participants, 2 trials) with an ultrasound-guided injection. In five trials (350 participants), 101/175 (or 606 per 1000) people in the ultrasound-guided group reported treatment success compared with 68/175 (or 389 per 1000) people in the group injected without image guidance (RR 1.56 (95% CI 0.89 to 2.75)), an absolute difference of 22% more reported success (4% fewer to 62% more). Low-certainty evidence (downgraded for bias and imprecision) indicates that ultrasound-guided injections may not reduce the risk of adverse events compared to injections without image guidance. In five trials (402 participants), 38/200 (or 181 per 1000) people in the ultrasound-guided group reported adverse events compared with 51/202 (or 252 per 1000) in the non-image-guided injection group (RR 0.72 (95% CI 0.4 to 1.28)), an absolute difference of 7% fewer adverse events (15% fewer to 7% more). Five trials reported that there were no serious adverse events. The remaining trials did not report serious adverse events. One trial reported that 1/53 (or 19 per 1000) in the injection without image guidance group and 0/53 in the ultrasound-guided group withdrew due to adverse events. Sensitivity analyses indicate that the effects for pain and function may have been influenced by selection bias, and the effects for function may have been influenced by detection bias. The test for subgroup differences indicated there were unlikely to be differences in pain and function across different shoulder conditions.

AUTHORS' CONCLUSIONS

Our updated review does not support use of image guidance for injections in the shoulder. Moderate-certainty evidence indicates that ultrasound-guided injection in the treatment of shoulder pain probably provides little or no benefit over injection without imaging in terms of pain or function and low-certainty evidence indicates there may be no difference in quality of life. We are uncertain if ultrasound-guided injection improves participant-rated treatment success, due to very low-certainty evidence. Low-certainty evidence also suggests ultrasound-guided injection may not reduce the risk of adverse events compared with non-image-guided injection. No serious adverse events were reported in any trial. The lack of significant benefit of image guidance over injection without image guidance to improve patient-relevant outcomes or reduce harms, suggests that any added cost of image guidance appears unjustified.

The efficacy of physiotherapy interventions in the treatment of adhesive capsulitis: A systematic review

BACKGROUND

Adhesive capsulitis is a debilitating condition which causes the capsule of the gleno-humeral joint to thicken and contract progressively. The effectiveness of various non-operative methods has been demonstrated to improve the pain, range of motion (ROM) and functional status of patients with adhesive capsulitis.

OBJECTIVE

This study aims to review recent evidence on the efficacy of physiotherapy interventions in the treatment of adhesive capsulitis.

METHODS

PubMed, Physiotherapy Evidence Database (PEDro), Science Direct and Cochrane databases were searched for studies published since 2013. The search terms included: Frozen shoulder, adhesive capsulitis, physical therapy, rehabilitation, manual therapy, mobilization, exercise, education, and electrotherapy. The search was limited to studies published in English and studies that used human subjects.

RESULTS

Quality scores of 33 articles were reviewed according to the Sackett's critical appraisal criteria and the grades of recommendation were determined for physiotherapy interventions used in the studies.

CONCLUSION

The empirical evidence suggests that certain physical therapy techniques and modalities are strongly recommended for pain relief, improvement of ROM, and functional status in patients with adhesive capsulitis, while others are either moderately or mildly recommended. However, the efficacy of one treatment modality over another is uncertain. The poor methodological rigors demonstrated in most of the reviewed studies emphasize the urgent need of properly conducted, adequately sampled randomized controlled trials with adequate follow up to determine the superior combination of treatment.

Treatment of Primary Shoulder Stiffness: Results of a Survey on Surgeon Practice Patterns in Italy

Objectives  Shoulder stiffness is a condition of restricted glenohumeral range of motion (ROM), which can arise spontaneously or as consequence of a known cause. Several treatment options are available and currently no consensus has been obtained on which treatment algorithm represents the best choice for the patient. The aim of this study was to investigate surgeon practice patterns in Italy regarding treatment of primary shoulder stiffness.

Methods  A literature review was performed to identify randomized controlled trials reporting results of shoulder stiffness treatment. The following controversial or critical points in the treatment of primary shoulder stiffness were identified: modalities of physical therapy; indication for oral corticosteroid; indication and frequency for injective corticosteroid; technique and site of injection; and indication, timing, and technique for surgery. A survey composed by 14 questions was created and administrated to the members of a national association specialized in orthopaedics and sports traumatology (SIGASCOT at the time of survey completion, recently renamed SIAGASCOT after the fusion of the societies SIGASCOT and SIA).

Results  A total of 204 completed questionnaires were collected. Physical therapy was recommended by 98% of the interviewed. The use of oral corticosteroids was considered by 51%, and injections of corticosteroids by 72%. The posterior injection approach was the one preferred and a number of three was considered the upper limit for repeated injections. Injective therapy with local anesthetics and hyaluronic acid was considered by more than 20% of the interviewed. Thirty percent of the interviewed did not treat shoulder stiffness surgically.

Conclusion  Several approaches to shoulder stiffness have been proposed and high-level evidence is available to analyze and discuss their results. Several controversial points emerged both from a literature review and from this national survey. Treatment of shoulder stiffness should be tailored to the patient's clinical situation and the stage of its pathology and should aim at pain reduction, ROM restoration, functional regain, and shortening of symptoms duration, with conservative therapy remaining the mainstay of treatment.

Clinical Guidelines in the Management of Frozen Shoulder: An Update!

Among all the prevalent painful conditions of the shoulder, frozen shoulder remains one of the most debated and ill-understood conditions. It is a condition often associated with diabetes and thyroid dysfunction, and which should always be investigated in patients with a primary stiff shoulder. Though the duration of 'traditional clinicopathological staging' of frozen shoulder is not constant and varies with the intervention(s), the classification certainly helps the clinician in planning the treatment of frozen shoulder at various stages. Most patients respond very well to combination of conservative treatment resulting in gradual resolution of symptoms in 12-18 months. However, the most effective treatment in isolation is uncertain. Currently, resistant cases that do not respond to conservative treatment for 6-9 months could be offered surgical treatment as either arthroscopic capsular release or manipulation under anaesthesia. Though both invasive options are not clinically superior to another, but manipulation could result in unwarranted complications like fractures of humerus or rotator cuff tear.

[Pediatric pain treatment and prevention for hospitalized children]

INTRODUCTION

Prevention and treatment of pain in pediatric patients compared with adults is often not only inadequate but also less often implemented the younger the children are. Children 0 to 17 years are a vulnerable population.

OBJECTIVES

To address the prevention and treatment of acute and chronic pain in children, including pain caused by needles, with recommended analgesic starting doses.

METHODS

This Clinical Update elaborates on the 2019 IASP Global Year Against Pain in the Vulnerable "Factsheet Pain in Children: Management" and reviews best evidence and practice.

RESULTS

Multimodal analgesia may include pharmacology (eg, basic analgesics, opioids, and adjuvant analgesia), regional anesthesia, rehabilitation, psychological approaches, spirituality, and integrative modalities, which act synergistically for more effective acute pediatric pain control with fewer side effects than any single analgesic or modality. For chronic pain, an interdisciplinary rehabilitative approach, including physical therapy, psychological treatment, integrative mind-body techniques, and normalizing life, has been shown most effective. For elective needle procedures, such as blood draws, intravenous access, injections, or vaccination, overwhelming evidence now mandates that a bundle of 4 modalities to eliminate or decrease pain should be offered to every child every time: (1) topical anesthesia, eg, lidocaine 4% cream, (2) comfort positioning, eg, skin-to-skin contact for infants, not restraining children, (3) sucrose or breastfeeding for infants, and (4) age-appropriate distraction. A deferral process (Plan B) may include nitrous gas analgesia and sedation.

CONCLUSION

Failure to implement evidence-based pain prevention and treatment for children in medical facilities is now considered inadmissible and poor standard of care.

Comparison of Treatments for Frozen Shoulder: A Systematic Review and Meta-analysis

IMPORTANCE

There are a myriad of available treatment options for patients with frozen shoulder, which can be overwhelming to the treating health care professional.

OBJECTIVE

To assess and compare the effectiveness of available treatment options for frozen shoulder to guide musculoskeletal practitioners and inform guidelines.

DATA SOURCES

Medline, EMBASE, Scopus, and CINHAL were searched in February 2020.

STUDY SELECTION

Studies with a randomized design of any type that compared treatment modalities for frozen shoulder with other modalities, placebo, or no treatment were included.

DATA EXTRACTION AND SYNTHESIS

Data were independently extracted by 2 individuals. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Random-effects models were used.

MAIN OUTCOMES AND MEASURES

Pain and function were the primary outcomes, and external rotation range of movement (ER ROM) was the secondary outcome. Results of pairwise meta-analyses were presented as mean differences (MDs) for pain and ER ROM and standardized mean differences (SMDs) for function. Length of follow-up was divided into short-term (≤12 weeks), mid-term (>12 weeks to ≤12 months), and long-term (>12 months) follow-up.

RESULTS

From a total of 65 eligible studies with 4097 participants that were included in the systematic review, 34 studies with 2402 participants were included in pairwise meta-analyses and 39 studies with 2736 participants in network meta-analyses. Despite several statistically significant results in pairwise meta-analyses, only the administration of intra-articular (IA) corticosteroid was associated with statistical and clinical superiority compared with other interventions in the short-term for pain (vs no treatment or placebo: MD, -1.0 visual analog scale [VAS] point; 95% CI, -1.5 to -0.5 VAS points; P < .001; vs physiotherapy: MD, -1.1 VAS points; 95% CI, -1.7 to -0.5 VAS points; P < .001) and function (vs no treatment or placebo: SMD, 0.6; 95% CI, 0.3 to 0.9; P < .001; vs physiotherapy: SMD 0.5; 95% CI, 0.2 to 0.7; P < .001). Subgroup analyses and the network meta-analysis demonstrated that the addition of a home exercise program with simple exercises and stretches and physiotherapy (electrotherapy and/or mobilizations) to IA corticosteroid may be associated with added benefits in the mid-term (eg, pain for IA coritocosteriod with home exercise vs no treatment or placebo: MD, -1.4 VAS points; 95% CI, -1.8 to -1.1 VAS points; P < .001).

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that the early use of IA corticosteroid in patients with frozen shoulder of less than 1-year duration is associated with better outcomes. This treatment should be accompanied by a home exercise program to maximize the chance of recovery.

Ultra-shortwave diathermy - a new purported treatment for management of patients with COVID-19

The pandemic spread of coronavirus disease 2019 (COVID-19) has driven efforts to address the global threat to public health and there is increasing pressure to exploit interventions to manage the pneumonic inflammation manifested in this disease. Ultra-shortwave diathermy (USWD) is proposed by some rehabilitation professions in China, purportedly to minimise pneumonic inflammation. However, treatment of any symptomatic pneumonia should be evidence-based. There is no valid evidence, published in English, which establishes any benefit of USWD in pulmonary conditions, let alone COVID-19. The need for rigorous research and evidence-based practice is discussed in this article. Novel interventions require a solid physiological basis and must undergo rigorous testing prior to clinical adoption even during a pandemic. We are of the view that deployment of USWD in patients with COVID-19 must be prudent and supported by a logical scientific basis.

'Frozen shoulder' is ill-defined. How can it be described better?

Frozen shoulder, a common and debilitating shoulder complaint, has been the subject of uncertainty within the scientific literature and clinical practice.

We performed an electronic PubMed search on all (1559) articles mentioning ‘frozen shoulder’ or ‘adhesive capsulitis’ to understand and qualify the range of naming, classification and natural history of the disease. We identified and reviewed six key thought leadership papers published in the past 10 years and all (24) systematic reviews published on frozen shoulder or adhesive capsulitis in the past five years.

This revealed that, while key thought leaders such as the ISAKOS Upper Extremity Council are unequivocal that ‘adhesive capsulitis’ is an inappropriate term, the long-term and short-term trends showed the literature (63% of systematic reviews assessed) preferred ‘adhesive capsulitis’.

The literature was divided as to whether or not to classify the complaint as primary only (9 of 24) or primary and secondary (9 of 24); six did not touch on classification.

Furthermore, despite a systematic review in 2016 showing no evidence to support a three-phase self-limiting progression of frozen shoulder, 11 of 12 (92%) systematic reviews that mentioned phasing described a three-phase progression. Eight (33%) described it as ‘self-limiting’, three (13%) described it as self-limiting in ‘nearly all’ or ‘most’ cases, and six (25%) stated that it was not self-limiting; seven (29%) did not touch on disease resolution.

We call for a data and patient-oriented approach to the classification and description of the natural history of the disease, and recommend authors and clinicians (1) use the term ‘frozen shoulder’ over ‘adhesive capsulitis’, (2) use an updated definition of the disease which recognizes the often severe pain suffered, and (3) avoid the confusing and potentially harmful repetition of the natural history of the disease as a three-phase, self-limiting condition.

Shoulder joint mobility in patients with primary adhesive capsulitis after treatment with continuous mode of ultrasound: A systematic review of randomized controlled trials

Background: Although the continuous mode of ultrasound therapy improves joint mobility, its role in primary adhesive capsulitis (AC) remains unclear. Therefore, this systematic review aims to address this evidence gap.

Methods: The literature search included databases (SCOPUS, CINAHL, EMBASE, and PubMed) and in-text references of articles read full-text. Randomized controlled trials (RCT) on primary AC patients (published in the English language between 1979-2019) comparing the ROM changes (in degrees) mainly between continuous mode of US therapy with any other non-electrotherapeutic treatment were eligible for inclusion. The trials were reviewed narratively along with an assessment of the risk of bias.

Results: Out of 174 search results, two eligible single-center trials comprising of 100 participants compared ROM in four separate directions at the 10th session and after three months post-intervention. The risk of selection bias, performance bias, and attrition bias was unclear among the trials. While in both the trials ROM (in all directions) improved in the respective intervention groups at follow up, most of these changes varied between the intervention groups in one trial. However, in the latter trial, participants in the treatment group had the worst ROM values at baseline with poor compliance to the adjunct exercise therapy.

Conclusion: The contemporary evidence in the context remains inconclusive due to a lack of large multicentric well-conducted RCTs.

The effectiveness of extracorporeal shockwave therapy for frozen shoulder in patients with diabetes: randomized control trial

[Purpose] This study examined the effectiveness of extracorporeal shock wave therapy versus ultrasound therapy, combined with the mobilization and therapeutic exercise in both groups, in participants with diabetic frozen shoulder. [Participants and Methods] Twenty participants with diabetic frozen shoulder were divided into an experimental group who received extracorporeal shock wave therapy, mobilization and exercises (n=10, Mean: 43.70) and the control group who received ultrasound, mobilization and exercises (n=10 Mean: 45.50). The clinical outcomes, i.e., a) pain b) active range of motions of the shoulder, c) disability scores by Disabilities of the Arm, Shoulder and Hand scale and d) global rating of change was measured weekly for four weeks. [Results] Significant improvements in pain, all active range of motions and disability scores were observed at the end of the 4th week in both groups. Additionally, the experimental group benefitted significant pain reduction (median difference: 7 in experimental versus 6 in control group), reduced number of therapy sessions and thus the costs of treatment compared to the control group. [Conclusion] Extracorporeal shock wave therapy significantly reduced pain in people with diabetic frozen shoulder with a reduction of treatment cost compared to the control group.

Physical therapy in the management of frozen shoulder

Frozen shoulder, also known as adhesive capsulitis, is a common presentation in the primary care setting and can be significantly painful and disabling. The condition progresses in three stages: freezing (painful), frozen (adhesive) and thawing, and is often self-limiting. Common conservative treatments include nonsteroidal anti-inflammatory drugs, oral glucocorticoids, intra-articular glucocorticoid injections and/or physical therapy. However, many physicians may find themselves limited to prescribing medications for treatment. This article elaborates on physical therapy exercises targeted at adhesive capsulitis, which can be used in combination with common analgesics.

Motion style acupuncture therapy for shoulder pain: a randomized controlled trial

Background

Strategies for preventing the persistence of pain and disability beyond the acute phase in shoulder pain patients are critically needed. Conventional acupuncture therapy (CAT) or motion style acupuncture therapy (MSAT) alone results in relative improvements in painful conditions in shoulder pain patients; combined interventions may have more global effects. The aim of this study is to evaluate the efficacy and safety of MSAT vs CAT for shoulder pain.

Methods

A randomized controlled trial using a factorial design was conducted from January 2014 to December 2015. Patients with a primary complaint of one-sided shoulder pain participated at three study sites. Eligible individuals were randomly assigned to receive MSAT plus minimal CAT (mCAT), CAT plus minimal MSAT (mMSAT), MSAT plus CAT, or mMSAT plus mCAT for 6 weeks in a 1:1:1:1 ratio. The primary outcome was change in shoulder pain intensity (measured using visual analog scale). The secondary outcomes included change in function of the shoulder joint (Constant–Murley score) and the health-related quality of life (Short Form-36 Health Survey). Moreover, perceived credibility of acupuncture was measured using the Treatment Credibility Scale. The outcomes were assessed at baseline and at 6, 10, and 18 weeks after randomization. Analysis of covariance with the baseline score adjustment had been used to determine the primary end point. The between-group differences of MSAT vs mMSAT and CAT vs mCAT were estimated, respectively, after tests of interaction between the two-dimensional interventions. All main analyses followed the intention-to-treat principle.

Results

A total of 164 patients completed the study. MSAT was superior to mMSAT in alleviating pain intensity at 10 weeks (P=0.024), and it was maintained for 18 weeks (P=0.013). Statistically significant differences were found when comparing MSAT with mMSAT for improvement in shoulder function (6 weeks, P=0.01; 10 weeks, P=0.006; and 18 weeks, P=0.01), physical health (10 weeks, P=0.023 and 18 weeks, P=0.015), and mental health (18 weeks, P=0.05). No significant differences were found in CAT when compared with mCAT.

Conclusion

After 18 weeks of treatment, pain and joint functions are improved more with MSAT than with minimal motion style acupuncture or conventional acupuncture in patients with shoulder pain.

Creation of a core outcome set for clinical trials of people with shoulder pain: a study protocol

Background

The selection of appropriate outcomes or domains is crucial when designing clinical trials, to appreciate the effects of different interventions, pool results, and make valid comparisons between trials. If the findings are to influence policy and practice, then the chosen outcomes need to be relevant and important to key stakeholders, including patients and the public, healthcare professionals and others making decisions about health care. There is a growing recognition that insufficient attention has been paid to the outcomes measured in clinical trials. Recent reviews of the measurement properties of patient-reported outcome measures for shoulder disorders revealed a large selection of diverse measures, many with questionable validity, reliability, and responsiveness. These issues could be addressed through the development and use of an agreed standardized collection of outcomes, known as a core outcome set (COS), which should be measured and reported in all trials of shoulder disorders. The purpose of the present project is to develop and disseminate a COS for clinical trials in shoulder disorders.

Methods/Design

The methods for the COS development will include 3 phases: (1) a comprehensive review of the core domains used in shoulder disorder trials; (2) an international Delphi study involving relevant stakeholders (patients, clinicians, scientists) to define which domains should be core; and (3) an international focus group informed by the evidence identified in phases 1 and 2, to determine which measurement instruments best measure the core domains and identification of any evidence gaps that require further empiric evidence.

Discussion

The aim of the current proposal is to convene several meetings of international experts and patients to develop a COS for clinical trials of shoulder disorders and to develop an implementation strategy to ensure rapid uptake of the core set of outcomes in clinical trials. There would be an expectation that the core set of outcomes would always be collected and reported, but it would not preclude use of additional outcomes in a particular trial.

Effective treatment options for musculoskeletal pain in primary care: A systematic overview of current evidence

BACKGROUND & AIMS

Musculoskeletal pain, the most common cause of disability globally, is most frequently managed in primary care. People with musculoskeletal pain in different body regions share similar characteristics, prognosis, and may respond to similar treatments. This overview aims to summarise current best evidence on currently available treatment options for the five most common musculoskeletal pain presentations (back, neck, shoulder, knee and multi-site pain) in primary care.

METHODS

A systematic search was conducted. Initial searches identified clinical guidelines, clinical pathways and systematic reviews. Additional searches found recently published trials and those addressing gaps in the evidence base. Data on study populations, interventions, and outcomes of intervention on pain and function were extracted. Quality of systematic reviews was assessed using AMSTAR, and strength of evidence rated using a modified GRADE approach.

RESULTS

Moderate to strong evidence suggests that exercise therapy and psychosocial interventions are effective for relieving pain and improving function for musculoskeletal pain. NSAIDs and opioids reduce pain in the short-term, but the effect size is modest and the potential for adverse effects need careful consideration. Corticosteroid injections were found to be beneficial for short-term pain relief among patients with knee and shoulder pain. However, current evidence remains equivocal on optimal dose, intensity and frequency, or mode of application for most treatment options.

CONCLUSION

This review presents a comprehensive summary and critical assessment of current evidence for the treatment of pain presentations in primary care. The evidence synthesis of interventions for common musculoskeletal pain presentations shows moderate-strong evidence for exercise therapy and psychosocial interventions, with short-term benefits only from pharmacological treatments. Future research into optimal dose and application of the most promising treatments is needed.

Comparative Efficacy of Platelet Rich Plasma Injection, Corticosteroid Injection and Ultrasonic Therapy in the Treatment of Periarthritis Shoulder

INTRODUCTION

Periarthritis (PA) shoulder characterised by pain and restricted range of motion has a plethora of treatment options with inconclusive evidence. Platelet Rich Plasma (PRP) is an emerging treatment option and its efficacy needs to be examined and compared with other routine interventions.

AIM

To assess the efficacy of PRP injection and compare it with corticosteroid injection and ultrasonic therapy in the treatment of PA shoulder.

MATERIALS AND METHODS

Patients with PA shoulder (n=195) were randomised to receive single injection of PRP (2 ml) or corticosteroid (80 mg of methylprednisolone) or ultrasonic therapy (seven sittings in two weeks; 1.5 W/cm², 1 MHz, continuous mode). All participants were also advised to perform a home based 10 minute exercise therapy. The primary outcome measure was active range of motion of the shoulder. Secondary outcome measures used were Visual Analogue Scale (VAS) for pain and a shortened version of Disabilities of the Arm, Shoulder and Hand (QuickDASH) for function. Participants were evaluated at 0, 3, 6 and 12 weeks. Chi-square test, one way and repeated measures of ANOVA tests were used to determine significant differences.

RESULTS

PRP treatment resulted in statistically significant improvements over corticosteroid and ultrasonic therapy in active as well as passive range of motion of shoulder, VAS and QuickDASH at 12 weeks. At six weeks, PRP treatment resulted in statistically significant improvements over ultrasonic therapy in VAS and QuickDASH. No major adverse effects were observed.

CONCLUSION

This study demonstrates that single injection of PRP is effective and better than corticosteroid injection or ultrasonic therapy in treatment of PA shoulder.

Manual therapy and exercise for rotator cuff disease

BACKGROUND

Management of rotator cuff disease often includes manual therapy and exercise, usually delivered together as components of a physical therapy intervention. This review is one of a series of reviews that form an update of the Cochrane review, 'Physiotherapy interventions for shoulder pain'.

OBJECTIVES

To synthesise available evidence regarding the benefits and harms of manual therapy and exercise, alone or in combination, for the treatment of people with rotator cuff disease.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), Ovid MEDLINE (January 1966 to March 2015), Ovid EMBASE (January 1980 to March 2015), CINAHL Plus (EBSCO, January 1937 to March 2015), ClinicalTrials.gov and the WHO ICTRP clinical trials registries up to March 2015, unrestricted by language, and reviewed the reference lists of review articles and retrieved trials, to identify potentially relevant trials.

SELECTION CRITERIA

We included randomised and quasi-randomised trials, including adults with rotator cuff disease, and comparing any manual therapy or exercise intervention with placebo, no intervention, a different type of manual therapy or exercise or any other intervention (e.g. glucocorticoid injection). Interventions included mobilisation, manipulation and supervised or home exercises. Trials investigating the primary or add-on effect of manual therapy and exercise were the main comparisons of interest. Main outcomes of interest were overall pain, function, pain on motion, patient-reported global assessment of treatment success, quality of life and the number of participants experiencing adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, extracted the data, performed a risk of bias assessment and assessed the quality of the body of evidence for the main outcomes using the GRADE approach.

MAIN RESULTS

We included 60 trials (3620 participants), although only 10 addressed the main comparisons of interest. Overall risk of bias was low in three, unclear in 14 and high in 43 trials. We were unable to perform any meta-analyses because of clinical heterogeneity or incomplete outcome reporting. One trial compared manual therapy and exercise with placebo (inactive ultrasound therapy) in 120 participants with chronic rotator cuff disease (high quality evidence). At 22 weeks, the mean change in overall pain with placebo was 17.3 points on a 100-point scale, and 24.8 points with manual therapy and exercise (adjusted mean difference (MD) 6.8 points, 95% confidence interval (CI) -0.70 to 14.30 points; absolute risk difference 7%, 1% fewer to 14% more). Mean change in function with placebo was 15.6 points on a 100-point scale, and 22.4 points with manual therapy and exercise (adjusted MD 7.1 points, 95% CI 0.30 to 13.90 points; absolute risk difference 7%, 1% to 14% more). Fifty-seven per cent (31/54) of participants reported treatment success with manual therapy and exercise compared with 41% (24/58) of participants receiving placebo (risk ratio (RR) 1.39, 95% CI 0.94 to 2.03; absolute risk difference 16% (2% fewer to 34% more). Thirty-one per cent (17/55) of participants reported adverse events with manual therapy and exercise compared with 8% (5/61) of participants receiving placebo (RR 3.77, 95% CI 1.49 to 9.54; absolute risk difference 23% (9% to 37% more). However adverse events were mild (short-term pain following treatment).Five trials (low quality evidence) found no important differences between manual therapy and exercise compared with glucocorticoid injection with respect to overall pain, function, active shoulder abduction and quality of life from four weeks up to 12 months. However, global treatment success was more common up to 11 weeks in people receiving glucocorticoid injection (low quality evidence). One trial (low quality evidence) showed no important differences between manual therapy and exercise and arthroscopic subacromial decompression with respect to overall pain, function, active range of motion and strength at six and 12 months, or global treatment success at four to eight years. One trial (low quality evidence) found that manual therapy and exercise may not be as effective as acupuncture plus dietary counselling and Phlogenzym supplement with respect to overall pain, function, active shoulder abduction and quality life at 12 weeks. We are uncertain whether manual therapy and exercise improves function more than oral non-steroidal anti-inflammatory drugs (NSAID), or whether combining manual therapy and exercise with glucocorticoid injection provides additional benefit in function over glucocorticoid injection alone, because of the very low quality evidence in these two trials.Fifty-two trials investigated effects of manual therapy alone or exercise alone, and the evidence was mostly very low quality. There was little or no difference in patient-important outcomes between manual therapy alone and placebo, no treatment, therapeutic ultrasound and kinesiotaping, although manual therapy alone was less effective than glucocorticoid injection. Exercise alone led to less improvement in overall pain, but not function, when compared with surgical repair for rotator cuff tear. There was little or no difference in patient-important outcomes between exercise alone and placebo, radial extracorporeal shockwave treatment, glucocorticoid injection, arthroscopic subacromial decompression and functional brace. Further, manual therapy or exercise provided few or no additional benefits when combined with other physical therapy interventions, and one type of manual therapy or exercise was rarely more effective than another.

AUTHORS' CONCLUSIONS

Despite identifying 60 eligible trials, only one trial compared a combination of manual therapy and exercise reflective of common current practice to placebo. We judged it to be of high quality and found no clinically important differences between groups in any outcome. Effects of manual therapy and exercise may be similar to those of glucocorticoid injection and arthroscopic subacromial decompression, but this is based on low quality evidence. Adverse events associated with manual therapy and exercise are relatively more frequent than placebo but mild in nature. Novel combinations of manual therapy and exercise should be compared with a realistic placebo in future trials. Further trials of manual therapy alone or exercise alone for rotator cuff disease should be based upon a strong rationale and consideration of whether or not they would alter the conclusions of this review.

Electrotherapy modalities for rotator cuff disease

BACKGROUND

Management of rotator cuff disease may include use of electrotherapy modalities (also known as electrophysical agents), which aim to reduce pain and improve function via an increase in energy (electrical, sound, light, or thermal) into the body. Examples include therapeutic ultrasound, low-level laser therapy (LLLT), transcutaneous electrical nerve stimulation (TENS), and pulsed electromagnetic field therapy (PEMF). These modalities are usually delivered as components of a physical therapy intervention. This review is one of a series of reviews that form an update of the Cochrane review, 'Physiotherapy interventions for shoulder pain'.

OBJECTIVES

To synthesise available evidence regarding the benefits and harms of electrotherapy modalities for the treatment of people with rotator cuff disease.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), Ovid MEDLINE (January 1966 to March 2015), Ovid EMBASE (January 1980 to March 2015), CINAHL Plus (EBSCOhost, January 1937 to March 2015), ClinicalTrials.gov and the WHO ICTRP clinical trials registries up to March 2015, unrestricted by language, and reviewed the reference lists of review articles and retrieved trials, to identify potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-randomised trials, including adults with rotator cuff disease (e.g. subacromial impingement syndrome, rotator cuff tendinitis, calcific tendinitis), and comparing any electrotherapy modality with placebo, no intervention, a different electrotherapy modality or any other intervention (e.g. glucocorticoid injection). Trials investigating whether electrotherapy modalities were more effective than placebo or no treatment, or were an effective addition to another physical therapy intervention (e.g. manual therapy or exercise) were the main comparisons of interest. Main outcomes of interest were overall pain, function, pain on motion, patient-reported global assessment of treatment success, quality of life and the number of participants experiencing adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, extracted the data, performed a risk of bias assessment and assessed the quality of the body of evidence for the main outcomes using the GRADE approach.

MAIN RESULTS

We included 47 trials (2388 participants). Most trials (n = 43) included participants with rotator cuff disease without calcification (four trials included people with calcific tendinitis). Sixteen (34%) trials investigated the effect of an electrotherapy modality delivered in isolation. Only 23% were rated at low risk of allocation bias, and 49% were rated at low risk of both performance and detection bias (for self-reported outcomes). The trials were heterogeneous in terms of population, intervention and comparator, so none of the data could be combined in a meta-analysis.In one trial (61 participants; low quality evidence), pulsed therapeutic ultrasound (three to five times a week for six weeks) was compared with placebo (inactive ultrasound therapy) for calcific tendinitis. At six weeks, the mean reduction in overall pain with placebo was -6.3 points on a 52-point scale, and -14.9 points with ultrasound (MD -8.60 points, 95% CI -13.48 to -3.72 points; absolute risk difference 17%, 7% to 26% more). Mean improvement in function with placebo was 3.7 points on a 100-point scale, and 17.8 points with ultrasound (mean difference (MD) 14.10 points, 95% confidence interval (CI) 5.39 to 22.81 points; absolute risk difference 14%, 5% to 23% more). Ninety-one per cent (29/32) of participants reported treatment success with ultrasound compared with 52% (15/29) of participants receiving placebo (risk ratio (RR) 1.75, 95% CI 1.21 to 2.53; absolute risk difference 39%, 18% to 60% more). Mean improvement in quality of life with placebo was 0.40 points on a 10-point scale, and 2.60 points with ultrasound (MD 2.20 points, 95% CI 0.91 points to 3.49 points; absolute risk difference 22%, 9% to 35% more). Between-group differences were not important at nine months. No participant reported adverse events.Therapeutic ultrasound produced no clinically important additional benefits when combined with other physical therapy interventions (eight clinically heterogeneous trials, low quality evidence). We are uncertain whether there are differences in patient-important outcomes between ultrasound and other active interventions (manual therapy, acupuncture, glucocorticoid injection, glucocorticoid injection plus oral tolmetin sodium, or exercise) because the quality of evidence is very low. Two placebo-controlled trials reported results favouring LLLT up to three weeks (low quality evidence), however combining LLLT with other physical therapy interventions produced few additional benefits (10 clinically heterogeneous trials, low quality evidence). We are uncertain whether transcutaneous electrical nerve stimulation (TENS) is more or less effective than glucocorticoid injection with respect to pain, function, global treatment success and active range of motion because of the very low quality evidence from a single trial. In other single, small trials, no clinically important benefits of pulsed electromagnetic field therapy (PEMF), microcurrent electrical stimulation (MENS), acetic acid iontophoresis and microwave diathermy were observed (low or very low quality evidence).No adverse events of therapeutic ultrasound, LLLT, TENS or microwave diathermy were reported by any participants. Adverse events were not measured in any trials investigating the effects of PEMF, MENS or acetic acid iontophoresis.

AUTHORS' CONCLUSIONS

Based on low quality evidence, therapeutic ultrasound may have short-term benefits over placebo in people with calcific tendinitis, and LLLT may have short-term benefits over placebo in people with rotator cuff disease. Further high quality placebo-controlled trials are needed to confirm these results. In contrast, based on low quality evidence, PEMF may not provide clinically relevant benefits over placebo, and therapeutic ultrasound, LLLT and PEMF may not provide additional benefits when combined with other physical therapy interventions. We are uncertain whether TENS is superior to placebo, and whether any electrotherapy modality provides benefits over other active interventions (e.g. glucocorticoid injection) because of the very low quality of the evidence. Practitioners should communicate the uncertainty of these effects and consider other approaches or combinations of treatment. Further trials of electrotherapy modalities for rotator cuff disease should be based upon a strong rationale and consideration of whether or not they would alter the conclusions of this review.

Interventions for treating bisphosphonate-related osteonecrosis of the jaw (BRONJ)

BACKGROUND

Bisphosphonate drugs can be used to prevent and treat osteoporosis and to reduce symptoms and complications of metastatic bone disease; however, they are associated with a rare but serious adverse event: osteonecrosis of the maxillary and mandibular bones. This condition is called bisphosphonate-related osteonecrosis of the jaw or BRONJ. BRONJ is diagnosed when people who are taking, or have previously taken, bisphosphonates have exposed bone in the jaw area for more than eight weeks in the absence of radiation treatment. There is currently no "gold standard" of treatment for BRONJ. The three broad categories of intervention are conservative approaches (e.g. mouth rinse, antibiotics), surgical interventions and adjuvant non-surgical strategies (e.g. hyperbaric oxygen therapy, platelet-rich plasma), which can be used in combination.

OBJECTIVES

To determine the efficacy and safety of any intervention aimed at treating BRONJ.

SEARCH METHODS

We searched the following databases to 15 December 2015: the Cochrane Oral Health Group Trials Register, the Cochrane Breast Cancer Group Trials Register (20 September 2011), the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via Ovid, EMBASE via Ovid, CancerLit via PubMed, CINAHL via EBSCO and AMED via Ovid. We scanned the references cited in retrieved articles and contacted experts in the field, the first authors of included papers, study sponsors, other bisphosphonates investigators and pharmaceutical companies. We searched for ongoing trials through contact with trialists and by searching the US National Institutes of Health Trials Register (clinicaltrials.gov) and the World Health Organization Clinical Trials Registry Platform. We also conducted a grey literature search to September 2015.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing the effects of any treatment for BRONJ with another treatment or placebo.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the search results, assessed the risk of bias in the included trials and extracted data. When in dispute, we consulted a third review author.

MAIN RESULTS

One small trial at high risk of bias met the inclusion criteria. The trial randomised 49 participants, most of whom had cancer. It compared standard care (defined as surgery, antibiotics and oral rinses at the discretion of the oral-maxillofacial surgeon) to standard care plus hyperbaric oxygen therapy (2 atmospheres twice a day for 40 treatments). The trial measured the percentage of participants who improved or healed at three, six, 12 and 18 months and last contact. It also measured mean weekly pain scores.At three months, the study found that the participants in intervention group were more likely to have an improvement in their osteonecrosis than the standard care group participants (risk ratio (RR) 1.94, 95% confidence interval (CI) 1.01 to 3.74). There was no clear difference between the groups for the outcome 'healed' at three months (RR 3.60, 95% CI 0.87 to 14.82). There was no clear difference between the groups for improvement or healing when they were evaluated at six, 12 and 18 months and last contact.The study did not give any information on adverse events.Although the findings suggest adjunctive hyperbaric oxygen improved BRONJ, the quality of the evidence is very low since the only study was underpowered and was at high risk of bias due to lack of blinding, cross-over of participants between groups and very high attrition (50% at 12 months and 80% at 18 months in this study, which was designed for an intended follow-up of 24 months).

AUTHORS' CONCLUSIONS

There is a lack of evidence from randomised controlled trials to guide treatment of bisphosphonate-related osteonecrosis of the jaw (BRONJ). One small trial at high risk of bias evaluated hyperbaric oxygen therapy (HBO) as an adjunct to "standard" care and could not confirm or refute the effectiveness of HBO. There are two ongoing trials of teriparatide treatment for BRONJ. We found no randomised controlled trials of any other BRONJ treatments. High quality randomised controlled trials are needed. We provide recommendations for their focus and design.

Core domain and outcome measurement sets for shoulder pain trials are needed: systematic review of physical therapy trials

OBJECTIVES

To explore the outcome domains and measurement instruments reported in published randomized controlled trials of physical therapy interventions for shoulder pain (rotator cuff disease, adhesive capsulitis, or nonspecific shoulder pain).

STUDY DESIGN AND SETTING

We included trials comparing physical therapy to any other intervention for shoulder pain, indexed up to March 2015 in CENTRAL, MEDLINE, EMBASE, or CINAHL Plus. Two authors independently selected trials for inclusion and extracted information on the domains and measurement instruments reported.

RESULTS

We included 171 trials. Most trials measured pain (87%), function (72%), and range of movement (67%), whereas adverse events, global assessment of treatment success, strength, and health-related quality of life were measured in 18-27% of trials, and work disability and referral for surgery were measured in less than 5% of trials. Thirty-five different measurement instruments for pain and 29 for function were noted. Measurement of function increased markedly from 1973 to 2014. In rotator cuff disease trials, there was a more frequent measurement of pain and strength and a less frequent measurement of range of movement compared with adhesive capsulitis trials.

CONCLUSIONS

There was wide diversity in the domains and measurement instruments reported. Our results provide the foundation for the development of a core domain and outcome measurement set for use in future shoulder pain trials.

Iontophoresis driven concentrations of topically administered diclofenac in skeletal muscle and blood of healthy subjects

PURPOSE

The present open single-centre, descriptive and comparative pharmacokinetic study aimed to investigate the efficacy of iontophoresis to enhance transdermal delivery by measuring concentration vs. time profiles of diclofenac in local tissue and in plasma in two separate study periods.

METHODS

Period 1 determined diclofenac concentrations in both calf muscles simultaneously by using microdialysis after applying diclofenac gel topically as a single dose of 5 g with or without iontophoresis in eight healthy volunteers. In period 2, the same dose was applied to another 8 volunteers to determine plasma concentrations of diclofenac either with or without iontophoresis in a cross over design.

RESULTS

In period 1, tissue concentrations were found to be under the limit of detection of 0.5 ng/ml both with and without iontophoresis in all subjects. In period 2, after iontophoresis in 75% of study participants, plasma concentrations of diclofenac could be determined, but only in 25% without iontophoresis. Although area under the concentration-time-curve (AUC, 187.97 ± 315.92 vs. 22.92 ± 42.44 ng*min/ml) and maximum concentration (Cmax, 2.06 ± 3.79 vs. 0.22 ± 0.41 ng/ml) values showed a numerically clear trend for higher values with iontophoresis compared to passive diffusion, no significant difference could be found due to high inter-individual variability. In total, 18.75% of all subjects presented adverse events.

CONCLUSIONS

Despite a higher percentage of subjects showed detectable plasma levels of diclofenac after iontophoresis, iontophoresis failed to achieve potentially more effective topical concentrations. The typical mechanism of iontophoresis like electromigration, electroosmosis and increased subcutaneous circulation could be responsible for the results of the present observation. Additional clinical studies are needed to justify the transdermal delivery of diclofenac by using iontophoresis.

Shoulder disorders and occupation

Shoulder pain is very common, and it causes substantial morbidity. Standardised classification systems based upon presumed patho-anatomical origins have proved poorly reproducible and hampered epidemiological research. Despite this, there is evidence that exposure to combinations of physical workplace strains such as overhead working, heavy lifting and forceful work as well as working in an awkward posture increases the risk of shoulder disorders. Psychosocial risk factors are also associated. There is currently little evidence to suggest that either primary prevention or treatment strategies in the workplace are very effective, and more research is required, particularly around the cost-effectiveness of different strategies.
