Interventions associated with an increased or decreased likelihood of pain reduction and improved function in patients with adhesive capsulitis: a retrospective cohort study

Comparative outcome of ultrasound guided vs. fluoroscopy guided hydrodilatation in adhesive capsulitis: a prospective study

BACKGROUND

The incidence of adhesive capsulitis varies from 2-5% in the general population to 20% in people with diabetes. One of the most effective treatment methods is hydrodilatation, which can be done under US-guidance or Fluoroscopic guidance. However, the clinical effectiveness of US-guided injections in comparison to fluoroscopy-guided injections is still debatable. The possibility of severe side effects, the expense, and the time required to carry out this minimally invasive procedure highlight how crucial it is for patients to have a precise intra-articular injection. This study aims to compare the effectiveness of Ultrasound-guided vs. Fluoroscopic guided hydrodilatation for patients with adhesive capsulitis.

METHODS

Sixty-four patients were randomly selected for hydrodilatation using any one of the techniques. The patients were evaluated for clinical improvements using the visual analog scale (VAS), oxford shoulder score (OSS), and range of motion (ROM).

RESULTS

The US-guided group experienced more pain reduction than the fluoroscopy group within the first four weeks (P < 0.001). The increase in ROM was much more significant in the US-guided group for the first 8 weeks. Improvement in Abduction and External rotation was much more significant (P < 0.001) in the first 4 weeks after hydrodilatation in the US-guided group. The improvement in ROM was maintained on long-term follow-up (mean 24 months), with 45 out of 64 (70.3%) reporting a normal or near normal ROM. On assessing the Oxford shoulder score improvements, the US-guided group's score significantly increased after the first week (P = 0.003), but the fluoroscopy-guided group's score increased after the second week. On comparison between the two groups, the amount of score improvement was more significant in the US-guided group than in the fluoroscopy-guided group in the first 4 weeks (P < 0.001).

CONCLUSION

US-guided technique for intra-articular injection for patients with adhesive capsulitis provided a quicker pain reduction and a larger improvement in range of motion and overall shoulder functions.

Effectiveness of electrophysical agents in subjects with frozen shoulder: a systematic review and meta-analysis

PURPOSE

This systematic review with meta-analysis aimed to assess the effectiveness of electrophysical agents in improving pain, function, disability, range of motion, quality of life, perceived stiffness, and time to recovery in subjects with frozen shoulder (FS).

METHODS

A thorough search of MEDLINE, Cochrane Library, PEDro, and EMBASE yielded 1143 articles, of which 23 randomized controlled trials were included. Risk of bias (RoB) was assessed through Cochrane Risk of Bias 2 tool. The certainty of evidence was evaluated through the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).

RESULTS

The analysis included a total of 1073 subjects. None of the studies were judged as low RoB. Potentially clinically significant differences were observed in pain at 6 weeks and 5 months after extracorporeal shockwave therapy (ESWT), and in disability up to 3 months with laser therapy, albeit with uncertain results due to the high RoB and to the study heterogeneity. Ultrasound (US) therapy did not yield significant differences in any outcomes. The certainty of evidence was very low.

CONCLUSIONS

Based on the high heterogeneity and low quality and certainty of evidence, ESWT, laser, and US cannot be recommended for FS treatment. Caution should be exercised in interpreting the findings.

The effects of end-range interventions in the management of primary adhesive capsulitis of the shoulder: a systematic review and meta-analysis

PURPOSE

To compare the effects of end-range manual therapy versus other conservative intervention on pain intensity, shoulder range of movement (ROM), and physical function in adhesive capsulitis (AC).

METHODS

Two reviewers conducted a comprehensive search from inception to December 2022. PUBMED, Cochrane Library, CINAHL, EMBASE, and PEDro databases were searched. Clinical trials investigating the effects of end-range mobilisation techniques on pain, ROM, and physical function in patients with AC were included. Methodological quality was evaluated using the PEDro scale, and bias risk was assessed using the Cochrane Collaboration tool. GRADE was used to assess the certainty of the evidence. Data were presented using forest plots, and the random effects models were applied according to the Cochrane handbook.

RESULTS

Ten randomised controlled trials were reviewed, involving 424 AC patients aged 20-70 years. Methodological quality of studies ranged from high to low. The end-range mobilisation showed improvements in pain intensity, shoulder abduction, internal rotation, and external rotation, and physical function compared to other conservative interventions in the short-and medium-terms. Certainty of the evidence was downgraded to very low.

CONCLUSIONS

Very low certainty evidence suggests that end-range mobilisation techniques improve pain intensity, shoulder ROM, and physical function in the short-and medium-term in AC.

Efficacy of a high-intensity home stretching device and traditional physical therapy in non-operative management of adhesive capsulitis - a prospective, randomized control trial

BACKGROUND

Historically, in-person physical therapy serves as a foundational component of nonoperative treatment of adhesive capsulitis (AC). This study compares the effectiveness of an at-home high-intensity stretch (HIS) device to traditional physical therapy (PT) and to PT in combination with the HIS device. We hypothesize that the HIS device will be as effective as PT alone or as combination therapy in the first-line treatment of AC and use of the HIS device will exhibit improvement at higher rate.

METHODS

Thirty-four patients with idiopathic adhesive capsulitis and a minimum of 12 months follow-up were included in this study. Patients were randomized into one of the three groups: HIS device, PT alone, or HIS device + PT. Passive range of motion (ROM), American Shoulder and Elbow Surgeons (ASES), and Simple Shoulder Test (SST) scores were measured. Additionally, patient satisfaction, compliance and complications were recorded. Paired t-test, ANOVA and Chi-squared tests were used in analysis.

RESULTS

Final ROM in all planes improved for all groups compared to baseline (p < 0.001), with only HIS device group able to restore > 95% of contralateral ROM in all planes at final follow-up. Patients with PT alone were on average slowest to improve ROM from baseline, at 3 months, 6 months, and 1 year in all planes except internal rotation. ASES and SST scores improved for all groups when compared to baseline (p < 0.001). Use of HIS-device resulted in greater improvement in SST and ASES Total scores compared to PT alone (p = 0.045, and p = 0.048, respectively).

CONCLUSIONS

Use of an at-home high-intensity stretching device for conservative treatment of idiopathic adhesive capsulitis improves outcomes in ROM and in ASES and SST scores both when used as an adjunct to physical therapy and when used alone.

Arthroscopic capsular release is more effective in pain relief than conservative treatment in patients with frozen shoulder

BACKGROUND

Frozen shoulder is a common medical condition, but the ideal therapeutic method is yet to be determined. Our aim was to analyze the pain-relieving effect of different treatment options used for the management of this disease.

METHODS

Medical records of 59 patients (22 male, 37 female, average age: 55.5 years ±9.9) with early stage primary frozen shoulder were evaluated, their demographic data, physical examination, concomitant diseases and treatment specific data were registered. Life quality and the level of pain were assessed using the Oxford Shoulder Score (OSS) and Numeric Rating Scale (NRS). Different treatment modalities and their effect on pain relief were recorded. Any existing correlation between life quality, pain and demographic data, concomitant diseases or the therapeutic method used was investigated.

RESULTS

The level of pain measured on NRS improved from 7.9 ± 1.6 to 1.9 ± 2.2. The most effective therapeutic method in terms of pain relief was surgery, followed by physiotherapy and intraarticular steroid injection (NRS score after treatment: 2 - p < 0.0001; 3.3 - p < 0.0001; 4.9 - p < 0.0001, respectively). Non-steroidal anti-inflammatory drugs (NSAIDs) did not reduce pain significantly. OSS improved from 24 to 43.6 and was not affected by the investigated variables, time to recovery was not influenced by the demographic data, the type of treatment or concomitant diseases.

CONCLUSIONS

Arthroscopic capsular release, physiotherapy and intraarticular steroid injection outperformed physical therapy and NSAID treatment in terms of pain relief. Despite of slight but persistent post-therapeutic pain found in half of the cases, treatment was considered satisfactory by the patients. Nor patient specific neither therapy specific data had a significant effect on the course of the disease.

Managing painful shoulder after neurological injury

Shoulder pain is common after neurological injury and can be disabling, lead to poor functional outcomes and increase care costs. Its cause is multifactoral and several pathologies contribute to the presentation. Astute diagnostic skills and a multidisciplinary approach are required to recognise what is clinically relevant and to implement appropriate stepwise management. In the absence of large clinical trial data, we aim to provide a comprehensive, practical and pragmatic overview of shoulder pain in patients with neurological conditions. We use available evidence to produce a management guideline, taking into account specialty opinions from neurology, rehabilitation medicine, orthopaedics and physiotherapy.

Effects of Exercise Intervention (with and without Joint Mobilization) in Patients with Adhesive Capsulitis: A Systematic Review and Meta-Analysis

This review aimed to investigate the effects of exercise and exercise with joint mobilization on shoulder range of motion (ROM) and subjective symptom recovery in patients with adhesive capsulitis (AC). Related Studies published from 2000 to 2021 that were peer-reviewed and for which pre-and post-values could be calculated were extracted from PubMed, CINAHL, SPORTDiscus, and Web of Science. Nine studies met our inclusion criteria. As a result of calculating the standard mean difference (SMD) and 95% confidence intervals (CI), both exercise and exercise with joint mobilization showed a large effect on shoulder ROM and subjective outcomes. The combination showed a more significant effect than exercise alone on shoulder flexion (SMD = -1.59 [-2.34, -0.65]), extension (SMD = -1.47 [-2.05, -0.89]), internal rotation (SMD = -1.77 [-2.17, -1.36], external rotation (SMD = -2.18 [-2.92, -1.44]), and abduction ROM (SMD = -1.99 [CI -3.86, -0.12]). Patients who performed exercise alone showed a higher effect of improvement in subjective function (SMD = 3.15 [2.06, 4.24]) and pain (SMD = 4.13 [1.86, 6.41]). Based on these results, an AC rehabilitation exercise program should be developed by adjusting the amount of exercise and joint mobilization by identifying the patient's needs, subjective symptoms, and ROM.

Suprascapular Nerve Block (SSNB) improves the outcome in exercise based management of Primary Adhesive Capsulitis (PAC): A prospective randomized comparative study

Background and Aims

Increased pain and associated stiffness hinders the advantages of exercise and process of recovery in primary adhesive capsulitis. We hypothesized that suprascapular nerve block may positively affect the outcome due to its role in pain relief of acute or chronic shoulder pain. We compared the effect of suprascapular nerve block and exercise with only exercise on the recovery of primary adhesive capsulitis.

Material and Methods

A total of 96 patients of both sexes presenting with primary adhesive capsulitis were divided by computer randomization in two equal groups (n = 48). Group A received exercise only and Group B received suprascapular nerve block followed by exercise. Oral paracetamol was given for analgesia as desired. Patients were followed up at 4, 8, 16, and 24 weeks. Pain was assessed by visual analog scale; functional outcome by Shoulder Pain and Disability Index and range of movement by goniometer.

Results

The pain scores and Shoulder Pain and Disability Index scores were significantly lower at all observation points of 4, 8,16, and 24 weeks in Group B than Group A (P < 0.05). The range of movement in all the ranges of forward flexion, extension, internal and external rotation, and abduction at all observation points was significantly higher in Group-B (P < 0.05) compared to Group A. The consumption of analgesics was significantly more in Group A than Group B at 4 and 8 weeks (P = 0.020 and P = 0.044) but comparable at 12 and 24 weeks (P = 0.145 and P = 0.237 respectively).

Conclusion

Combining SSNB with exercise is more effective in treatment of primary adhesive capsulitis than exercise alone and reduces the use of analgesics. SSNB it is effective and safe to use in primary adhesive capsulitis.

Instrument assisted soft tissue mobilization in adhesive capsulitis: A randomized clinical trial

INTRODUCTION

Shoulder adhesive capsulitis is a common pathology in middle aged population, physical therapy being the mainstay treatment for it. Various conventional treatment modalities have been proven to help in this condition. Instrument Assisted Soft Tissue Mobilization (IASTM) is a considerably new technique, which is being used widely for various sports related injuries for a faster recovery. This study proposes to evaluate the effect of IASTM as an added treatment for improving pain, range of motion and functional ability in patients with adhesive capsulitis.

METHOD

30 shoulders were randomly allocated into two groups- Group A (IASTM + conventional treatment) and Group B (conventional treatment). Treatment was given for 12 sessions, 3 sessions per week for 4 weeks. Participants were evaluated pre treatment, post 6th session and post 12th session. Outcome measures was Numerical Pain Rating Scale, Shoulder Pain And Disability Index, Shoulder Range of Motion, Apley's scratch test.

RESULTS

Pain and Disability scale had shown improvement within the group only. However, in experimental group significant improvement was seen in active and passive mobility including functional performance.

CONCLUSION

IASTM along with conventional protocol was able to improve mobility and function among adhesive capsulitis patients.

Effectiveness of radial extracorporeal shock-wave therapy versus ultrasound-guided low-dose intra-articular steroid injection in improving shoulder pain, function, and range of motion in diabetic patients with shoulder adhesive capsulitis

To compare the efficacy of radial extracorporeal shock-wave therapy (rESWT) vs. an ultrasound-guided low-dose intra-articular steroid injection in pain reduction and functional improvement in diabetic patients with shoulder adhesive capsulitis (AC).

METHODS

This was a 2-parallel-group, active-control, assessor-blinded, randomized trial. We randomized 103 diabetic patients with shoulder AC to receive either 4 sessions of rESWT, 1 week apart (rESWT group, n = 52), or a single ultrasound-guided low-dose intra-articular steroid injection of 20 mg of triamcinolone acetonide (steroid group, n = 51). The primary outcome measure was functional improvement evaluated by the Quick Disabilities of the Arm, Shoulder and Hand (qDASH) score. Secondary outcome measures were pain evaluated by the visual analog scale score and shoulder range of motion (ROM). An assessor who was blinded to treatment assignment assessed both groups at baseline and at 4, 8, and 12 weeks thereafter.

RESULTS

By 12 weeks, both groups demonstrated a significant reduction in the qDASH score and pain severity, as well as improvement in ROM. However, significantly improved function (qDASH score, 40.4 ± 12.9 vs. 50.5 ± 13.3; P < .001) and shoulder pain reduction (visual analog scale score, 1.6 ± 1.2 vs. 2.8 ± 1.7; P < .001) were found in the rESWT group vs. the steroid group. Similar improvement in shoulder ROM was observed in both groups.

CONCLUSION

At short-term follow-up, rESWT was superior to a low-dose intra-articular steroid injection in improving function and pain in diabetic patients with shoulder AC. Therefore, rESWT might be considered a safe alternative to steroid injections in diabetic patients with shoulder AC.

A central nervous system-focused treatment approach for people with frozen shoulder: protocol for a randomized clinical trial

Background

Frozen shoulder (FS) is a musculoskeletal condition of poorly understood etiology that results in shoulder pain and large mobility deficits. Despite some physical therapy interventions, such as joint mobilization and exercise, having shown therapeutic benefit, a definitive treatment does not currently exist. The aim of this study will be to compare the effectiveness of a central nervous system (CNS)-directed treatment program versus a standard medical and physical therapy care program on outcomes in participants with FS.

Methods/design

The study is a two-group, randomized clinical trial with blinding of participants and assessors. Participants will be recruited via referrals from orthopedic surgeons and physical therapists, community-based advertisements, private care practices and hospitals. Participants will be randomized to receive either a CNS-focused treatment program or standard medical and physical therapy care. The Shoulder Pain And Disability Index (SPADI) will be the primary outcome, while the Numeric Pain Rating Scale (NPRS), shoulder range of movement (ROM), The Patient Specific Functional Scale, two-point discrimination threshold and laterality judgement accuracy will be the secondary outcomes. Assessment will occur at baseline, at the end of the treatment program (week 10), and at 3 and 6 months’ follow-up.

Discussion

Preliminary data suggest that treatments that target CNS function are a promising approach to the treatment of people with shoulder pain including patients with FS. In the context of modest effects from most available physical therapy treatments for FS, this CNS-focused approach may lead to improved clinical outcomes. The trial should determine if the CNS-directed program is more effective than traditional interventions at reducing pain intensity and improving function in a FS cohort and will follow up participants for 6 months, providing important information on the persistence of any treatment effects.

Efficacy of therapeutic ultrasound in treatment of adhesive capsulitis: A prospective double blind placebo-controlled randomized trial

BACKGROUND

In treatment of adhesive capsulitis, deep heating agents have been shown to have positive effects on pain and function.

OBJECTIVE

To evaluate if addition of ultrasound used in treatment of adhesive capsulitis will provide additional benefits.

METHODS

Thirty patients with adhesive capsulitis were included in a prospective, double-blind, randomized controlled trial. Hotpack, TENS (Transcutaneus Electrical Nerve Stimulation), exercise and active ultrasound therapies were applied to the first group (n= 15), whereas sham ultrasound was applied to the second group (n= 15) in addition to hotpack, TENS and exercise. The patients were evaluated using joint range of motion, UCLA shoulder scale and Shoulder Disability Questionnaire scales at baseline and at 6th and 24th weeks post-treatment.

RESULTS

When pain and the clinical and functional parameters were compared in both groups, significant improvement was found compared to baseline (p< 0.001). At week 24, no difference was found in terms of pain at rest, but all other parameters were improved compared to week 6. When the groups were compared, no difference was found in any comparison between 6th and 24th week (p> 0.05).

CONCLUSION

Adding ultrasound treatment to a combination of physical therapy modalities did not provide any additional benefits for the treatment of adhesive capsulitis.

The effectiveness of conservative and surgical treatment for shoulder stiffness: a systematic review of current literature

INTRODUCTION

Currently, no therapeutic intervention is universally accepted, and the most effective management for restoring motion and diminishing pain in patients with shoulder stiffness has yet to be defined. This systematic review analyses outcomes of conservative and surgical interventions to treat shoulder stiffness.

SOURCE OF DATA

A systematic review of literature according to the PRISMA guidelines was performed. A comprehensive search of PubMed, Medline, CINAHL, Cochrane, Embase, Ovid and Google Scholar databases using various combinations of the keywords 'shoulder', 'shoulder stiffness', 'stiff shoulder', 'conservative', since inception of databases to June 2018 was performed.

AREAS OF AGREEMENT

Shoulder stiffness could be treated with conservative means including nonsteroidal anti-inflammatory medications, corticosteroid injections, or transcutaneous electrical nerve stimulation, manipulation under anaesthesia, and arthroscopic capsular release.

AREAS OF CONTROVERSY

No therapeutic intervention is universally accepted, and the most effective management to restore motion and diminish pain in patients with shoulder stiffness has yet to be defined.

GROWING POINTS

The rate of failure after treatment for stiff shoulder is higher in the surgical group than in the conservative group.

AREAS TIMELY FOR DEVELOPING RESEARCH

There is insufficient evidence to establish whether surgical or conservative management is the best choice to manage shoulder stiffness. Prospective, randomized studies are needed to establish whether surgical or conservative management produce a clinically relevant difference in functional outcome.

Effectiveness of translational manipulation under interscalene block for the treatment of adhesive capsulitis of the shoulder: A nonrandomized clinical trial

Study Design: Nonrandomized controlled trial. Objective: To determine whether translational manipulation under anesthesia/local block (TMUA) adds to the benefit of mobilization and range of motion exercise for improving pain and functional status among patients with adhesive capsulitis of the shoulder (AC). Background: TMUA has been shown to improve pain and dysfunction in patients with AC. This intervention has not been directly compared to physical therapy treatment without TMUA in a prospective trial. Methods: Sixteen consecutive patients with a primary diagnosis of AC were divided into two groups. Patients in the first (TMUA) group received a session of translational manipulation under interscalene block, followed by six sessions of manipulation and exercise. Patients in the comparison group received seven sessions of manipulation and exercise. Outcome measures taken at baseline and 3, 6, 12 months and 4 years included Shoulder Pain and Disability Index (SPADI) scores. Four-year outcomes included percent of normal ratings, medication use, and activity limitations. Results: Both groups showed improved SPADI scores across all follow-up times compared to baseline. The TMUA group showed a greater improvement in SPADI scores than the comparison group at 3 weeks, with no significant differences in SPADI scores at other time points. However, at 4 years, significantly more subjects in the comparison group (5 of 8) had activity limitations versus subjects in the TMUA group (1 of 8). No subject experienced a complication from either intervention protocol. Conclusion: Physical therapy consisting of manual therapy and exercise provides benefit for patients with AC. Translational manipulation under local block may be a useful adjunct to manual therapy and exercise for patients with AC.

Use of Pain Neuroscience Education, Tactile Discrimination, and Graded Motor Imagery in an Individual With Frozen Shoulder

Study Design Case report. Background Aggressive physical therapy in the freezing stage of frozen shoulder may prolong the course of recovery. Central sensitization may play a role in the early stages of frozen shoulder. Pain neuroscience education, tactile discrimination, and graded motor imagery have been used in a number of conditions with central sensitization. The purpose of this case report was to describe the examination and treatment of a patient in the freezing stage of frozen shoulder using pain neuroscience education, tactile discrimination, and graded motor imagery. Case Description A 54-year-old woman with a diagnosis of frozen shoulder was referred by an orthopaedic surgeon following lack of progress after 4 weeks of intensive daily physical therapy. Pain at rest was 7/10, and her Shoulder Pain and Disability Index score was 64%. She had painful and limited active range of motion and elevated fear-avoidance beliefs. Tactile discrimination and limb laterality were impaired, with signs of central sensitization. A "top-down" approach using pain neuroscience education, tactile discrimination, and graded motor imagery was used for the first 6 weeks, followed by a "bottom-up" impairment-based approach. Outcomes The patient was seen for 20 sessions over 12 weeks. At discharge, her Shoulder Pain and Disability Index score was 22%, resting pain was 0/10, and fear-avoidance beliefs improved. Improvements in active range of motion, laterality, and tactile discrimination were also noted. Discussion Intensive physical therapy in the freezing stage of frozen shoulder may be detrimental to long-term outcomes. This case report suggests that a top-down approach may allow a quicker transition through the freezing stage of frozen shoulder. Level of Evidence Therapy, level 5. J Orthop Sports Phys Ther 2018;48(3):174-184. Epub 19 Dec 2017. doi:10.2519/jospt.2018.7716.

Patient-reported measures of quality of life and functional capacity in adhesive capsulitis

Objective:

To evaluate patient-reported measures of quality of life and functional capacity in adhesive capsulitis before and after suprascapular nerve block treatment; to analyze the influence of clinical and sociodemographic variables on both the outcome and correlation between the respective instruments.

Method:

A prospective clinical study was performed with adhesive capsulitis patients. Inclusion criteria were clinical diagnosis of adhesive capsulitis and a shoulder imaging test. The WHOQOL-BREF and DASH instruments were administered before and after treatment. A Constant test score of 55 points was used as a cutoff point for discontinuation of treatment. Mean values were compared using paired t-test and Wilcoxon. The Pearson or Spearman coefficients were used for correlation analysis. Multiple linear regression analysis was carried out using variables with p<0.20 as predictors in univariate analysis and WHOQOL domains and DASH as outcomes. The significance level was 5%.

Results:

Forty-three patients were evaluated. The comparison between WHOQOL-BREF and DASH mean values before and after the blocks, p<0.05. DASH correlated negatively with the physical, psychological and environmental WHOQOL-BREF domains. Older patients and those with higher levels of education influenced the improvement in patients' quality of life and functional capacity.

Conclusion:

The improvement of adhesive capsulitis with treatment involves an improvement in quality of life and functional capacity. The greater functional capacity of the shoulder matches a better quality of life for patients. Age and education level are the variables that most influence improvement in quality of life and functional capacity.

Adhesive capsulitis of the shoulder: review of pathophysiology and current clinical treatments

Adhesive shoulder capsulitis, or arthrofibrosis, describes a pathological process in which the body forms excessive scar tissue or adhesions across the glenohumeral joint, leading to pain, stiffness and dysfunction. It is a debilitating condition that can occur spontaneously (primary or idiopathic adhesive capsulitis) or following shoulder surgery or trauma (secondary adhesive capsulitis). Here, we review the pathophysiology of adhesive shoulder capsulitis, highlighting its clinical presentation, natural history, risk factors, pathoanatomy and pathogenesis. Both current non-operative and operative treatments for adhesive capsulitis are described, and evidence-based studies are presented in support for or against each corresponding treatment. Finally, the review also provides an update on the gene expression profile of adhesive capsulitis and how this new understanding can help facilitate development of novel pharmacological therapies.

Adhesive Capsulitis of the Shoulder. Is there Consensus Regarding the Treatment? A Comprehensive Review

Background:

Adhesive capsulitis of the shoulder (ACS) is a common self-limiting condition characterized by disabling pain and restricted movements. Its pathophysiology is poorly understood, clinically it is characterized by stages of pain and stiffness, and finally often patients never recover fully. However, there is no consensus about available methods of treatment for ACS. The aims of this paper are to discuss and develop issues regarding approaches to management in ACS in the stages of it.

Methods:

A review of the literature was performed and guidelines for the treatment of that clinical entity for doctors and health care professionals are provided.

Results:

Anti-inflammatory medications, steroid and/or hyaluronate injections and physiotherapy is the mainstay of conservative management either alone in the first stages or in combination with other treatment modalities in the later stages. Next line of treatment, involving minor to moderate intervention, includes suprascapular nerve block, distension arthrography and manipulation under anaesthesia. In order to avoid complications of “blind intervention”, arthroscopic capsular release is gradually more commonly applied, and in recalcitrant severe cases open release is a useful option.

Conclusion:

Various modalities of conservative management and gradually more surgical release are applied. However, often clinicians choose on personal experience and training rather than on published evidence.

A systematic review of thrust manipulation for non-surgical shoulder conditions

Purpose

Although many conservative management options are available for patients with non-surgical shoulder conditions, there is little evidence of their effectiveness. This review investigated one manual therapy approach, thrust manipulation, as a treatment option.

Methods

A systematic search was conducted of the electronic databases from inception to March 2016: PubMed, PEDro, ICL, CINAHL, and AMED. Two independent reviewers conducted the screening process to determine article eligibility. Inclusion criteria were manuscripts published in peer-reviewed journals with human participants of any age. The intervention included was thrust, or high-velocity low-amplitude, manipulative therapy directed to the shoulder and/or the regions of the cervical or thoracic spine. Studies investigating secondary shoulder pain or lacking diagnostic confirmation procedures were excluded. Methodological quality was assessed using the PEDro scale and the Cochrane risk-of-bias tool.

Results

The initial search rendered 5041 articles. After screening titles and abstracts, 36 articles remained for full-text review. Six articles studying subacromial impingement syndrome met inclusion criteria. Four studies were randomized controlled trials (RCTs) and 2 were uncontrolled clinical studies. Five studies included 1 application of a thoracic spine thrust manipulation and 1 applied 8 treatments incorporating a shoulder joint thrust manipulation. Statistically significant improvements in pain scores were reported in all studies. Three of 4 RCTs compared a thrust manipulation to a sham, and statistical significance in pain reduction was found within the groups but not between them. Clinically meaningful changes in pain were inconsistent; 3 studies reported that scores met minimum clinically important difference, 1 reported scores did not, and 2 were unclear. Four studies found statistically significant improvements in disability; however, 2 were RCTs and did not find statistical significance between the active and sham groups.

Conclusions

No clinical trials of thrust manipulation for non-surgical shoulder conditions other than subacromial impingement syndrome were found. There is limited evidence to support or refute thrust manipulation as a solitary treatment for this condition. Studies consistently reported pain reduction, but active treatments were comparable to shams. High-quality studies of thrust manipulation with safety data, longer treatment periods and follow-up outcomes are needed.

De Quervain's Tenosynovitis and Phonophoresis: A Randomised Controlled Trial in Pregnant Females

Background

De Quervain's tenosynovitis is a common cause of wrist pain in pregnant and postpartum females. This study provides objective evidence regarding the therapeutic efficacy of phonophoresis in treating de Quervain's disease during pregnancy.

Methods

In a single blind, randomised, controlled trial (n = 50), ketoprofen phonophoresis was given to the intervention group and conventional ultrasound (US) was given to controls, coupled with thumb splint immobilisation, and supervised strengthening and stretching exercises for 1 month. Symptomatic and functional improvement was assessed by visual pain analogue, grip, tip, key, and palmer pinch scales.

Results

There was a statistically significant improvement in the intervention group compared to the control group in grip and pinch strength, and pain reduction.

Conclusion

Ketoprofen phonophoresis as an adjunct to supervised exercise and splint immobilisation is a safe and effective therapy for de Quervain's tenosynovitis during pregnancy. Phonophoresis augments the benefits of US in terms of reducing pain and inflammation, and improving functional strength.

Frozen shoulder contracture syndrome - Aetiology, diagnosis and management

Frozen shoulder is a poorly understood condition that typically involves substantial pain, movement restriction, and considerable morbidity. Although function improves overtime, full and pain free range, may not be restored in everyone. Frozen shoulder is also known as adhesive capsulitis, however the evidence for capsular adhesions is refuted and arguably, this term should be abandoned. The aim of this Masterclass is to synthesise evidence to provide a framework for assessment and management for Frozen Shoulder. Although used in the treatment of this condition, manipulation under anaesthetic has been associated with joint damage and may be no more effective than physiotherapy. Capsular release is another surgical procedure that is supported by expert opinion and published case series, but currently high quality research is not available. Recommendations that supervised neglect is preferable to physiotherapy have been based on a quasi-experimental study associated with a high risk of bias. Physiotherapists in the United Kingdom have developed dedicated care pathways that provide; assessment, referral for imaging, education, health screening, ultrasound guided corticosteroid and hydro-distension injections, embedded within physiotherapy rehabilitation. The entire pathway is provided by physiotherapists and evidence exists to support each stage of the pathway. Substantial on-going research is required to better understand; epidemiology, patho-aetiology, assessment, best management, health economics, patient satisfaction and if possible prevention.

Effectiveness of sustained stretching of the inferior capsule in the management of a frozen shoulder

BACKGROUND

Physiotherapy treatment of frozen shoulder is varied, but most lack specific focus on the underlying disorder, which is the adhered shoulder capsule. Although positive effects were found after physiotherapy, the recurrence and prolonged disability of a frozen shoulder are major factors to focus on to provide the appropriate treatment.

QUESTIONS/PURPOSES

We wished to study the effectiveness of a shoulder countertraction apparatus on ROM, pain, and function in patients with a frozen shoulder and compare their results with those of control subjects who received conventional physiotherapy.

METHODS

A total of 100 participants were randomly assigned to an experimental group and a control group, with each group having 50 participants. The control group received physiotherapy and the experimental group received countertraction and physiotherapy. The total treatment time was 20 minutes a day for 5 days per week for 2 weeks. The outcome measures used were goniometer measurements, VAS, and the Oxford Shoulder Score.

RESULTS

Improvements were seen in the scores for shoulder flexion (94.1° ± 19.79° at baseline increased to 161.9° ± 13.05° after intervention), abduction ROM (90.4° ± 21.18° at baseline increased to 154.8° ± 13.21° after intervention), and pain (8.00 ± 0.78 at baseline decreased to 3.48 ± 0.71 after intervention) in the experimental group. Sixty percent of the participants (n = 30) were improved to the fourth stage of satisfactory joint function according to the Oxford Shoulder Score in the experimental group compared with 18% (n = 9) in the control group (p < 0.001).

CONCLUSIONS

Incorporating shoulder countertraction along with physiotherapy improves shoulder function compared with physiotherapy alone for the treatment of a frozen shoulder. Additional studies are needed focusing on this concept to increase the generalizability of the counter-traction apparatus in various groups.

Trigger point dry needling as an adjunct treatment for a patient with adhesive capsulitis of the shoulder

STUDY DESIGN

Case report.

BACKGROUND

Prognosis for adhesive capsulitis has been described as self-limiting and can persist for 1 to 3 years. Conservative treatment that includes physical therapy is commonly advised.

CASE DESCRIPTION

The patient was a 54-year-old woman with primary symptoms of shoulder pain and loss of motion consistent with adhesive capsulitis. Manual physical therapy intervention initially consisted of joint mobilizations of the shoulder region and thrust manipulation of the cervicothoracic region. Although manual techniques seemed to result in some early functional improvement, continued progression was limited by pain. Subsequent examination identified trigger points in the upper trapezius, levator scapula, deltoid, and infraspinatus muscles, which were treated with dry needling to decrease pain and allow for higher grades of manual intervention.

OUTCOMES

The patient was treated for a total of 13 visits over a 6-week period. After trigger point dry needling was introduced on the third visit, improvements in pain-free shoulder range of motion and functional outcome measures, assessed with the Shoulder Pain and Disability Index and the shortened form of the Disabilities of the Arm, Shoulder and Hand questionnaire, exceeded the minimal clinically important difference after 2 treatment sessions. At discharge, the patient had achieved significant improvements in shoulder range of motion in all planes, and outcome measures were significantly improved.

DISCUSSION

This case report describes the clinical reasoning behind the use of trigger point dry needling in the treatment of a patient with adhesive capsulitis. The rapid improvement seen in this patient following the initiation of dry needling to the upper trapezius, levator scapula, deltoid, and infraspinatus muscles suggests that surrounding muscles may be a significant source of pain in this condition.

Efficacy of a static progressive stretch device as an adjunct to physical therapy in treating adhesive capsulitis of the shoulder: a prospective, randomised study

BACKGROUND

Stress relaxation and static progressive stretch are techniques used for non-surgical restoration of shoulder range of motion for patients with adhesive capsulitis.

OBJECTIVES

To compare a static progressive stretch device plus traditional therapy with traditional therapy alone for the treatment of adhesive capsulitis of the shoulder.

DESIGN

Prospective, randomised controlled trial.

PARTICIPANTS

Sixty patients with adhesive capsulitis of the shoulder were assigned at random to an experimental group or a control group.

INTERVENTIONS

Both groups received three traditional therapy sessions per week for 4 weeks. In addition, the experimental group used a static progressive stretch device for 4 weeks.

MAIN OUTCOME MEASURES

The primary outcome measure was shoulder range of motion (active and passive shoulder abduction, and passive shoulder external rotation). The secondary outcome measures were function [measured by the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire] and pain [measured using a visual analogue scale (VAS)].

RESULTS

At baseline, there were no differences between the two groups. However, after the intervention, there were significant (P<0.05) differences between the groups for all outcome parameters: 0.3 for mean VAS scores [95% confidence interval (CI) -0.6 to 1.1], -10.1 for DASH scores (95% CI -21.0 to 0.9), 21.2° for shoulder passive external rotation (95% CI 16.8 to 25.7), 26.4° for shoulder passive abduction (95% CI 17.4 to 35.3), and 27.7° for shoulder active abduction (95% CI 20.3 to 35.0). At 12-month follow-up, the differences between the groups were maintained and even increased for mean shoulder range of motion, VAS scores and DASH scores, with significant differences (P<0.001) between the groups: -2.0 for VAS scores (95% CI -2.9 to -1.2), -53.8 for DASH scores (95% CI -64.7 to -42.9), 47.9° for shoulder passive external rotation (95% CI 43.5 to 52.3), 44.9° for shoulder passive abduction (95% CI 36.0 to 53.8), and 94.3° for shoulder active abduction (95% CI 87.0 to 101.7).

CONCLUSION

Use of a static progressive stretch device in combination with traditional therapy appears to have beneficial long-term effects on shoulder range of motion, pain and functional outcomes in patients with adhesive capsulitis of the shoulder. At 12-month follow-up, the experimental group had continued to improve, while the control group had relapsed.

Effective therapeutic exercise prescription: the right exercise at the right dose

The prescription of an effective therapeutic exercise program requires the right dosage of the right exercise, at the right time for that patient. The therapist must understand and apply training principles effectively in the presence of pathology, injury, or otherwise unhealthy tissue. The intervention goal is to close the gap between current performance and the desired goal or capacity. Although there may be a preferred linear path from current performance to optimal outcome, complexities of the human body, internal factors, and external variables may create barriers to this direct path. Successful programs include key program design considerations such as ensuring a stable baseline before progression, treating the right impairments and activity limitations, understanding contextual factors, considering the principles of specificity and optimal loading, and applying dosing principles. Program progression can be achieved through increases in total exercise volume and/or through manipulation of exercise challenges at the same exercise volume. Effective application of these principles will guide patients toward their goals as quickly and efficiently as possible.

Referral source and outcomes of physical therapy care in patients with low back pain

STUDY DESIGN

Retrospective longitudinal cohort.

OBJECTIVES

To describe the clinical characteristics of patients with low back pain according to physician referral source, and to identify associations between referral source and discharge functional status, as well as number of physical therapy visits.

BACKGROUND

Little is known about associations between physician referral source and outcomes of physical therapy care for patients with low back pain. Exploring these associations can contribute to better understanding of physician-physical therapist relationships and may lead to improved referral patterns.

METHODS

Data from a proprietary clinical database were examined retrospectively. Physician referral source was classified as primary care, specialist, or occupational medicine. Outcomes were overall health status at discharge and number of physical therapy visits. Descriptive statistics and bivariate associations between referral source and each outcome were assessed by calculating differences and 95% confidence intervals (CIs) in means and proportions. To account for potential confounding, multilevel linear regression was used to adjust for baseline clinical covariates, effects related to clustering of patients treated by individual clinicians, and clinicians working within individual clinics.

RESULTS

Bivariate and multilevel analyses revealed significant associations between referral source and discharge overall health status, as well as number of visits. After multilevel adjustment for covariate and clustering effects, primary care and occupational medicine referrals were associated, on average, with point increases of 1.6 (95% CI: 0.7, 2.6) and 4.8 (95% CI: 2.7, 6.9) in discharge overall health status scores, respectively, compared to specialist referral. Similarly, primary care and occupational medicine referrals were associated, on average, with 0.44 (95% CI: 0.27, 0.61) and 0.83 (95% CI: 0.44, 1.22) fewer visits, respectively, compared to specialist referral.

CONCLUSION

After accounting for clinical covariates and clustering, patients with low back pain who were referred by occupational medicine and primary care physicians tended to have better functional outcomes and required fewer physical therapy visits per episode of care.

Secular trend of adhesive capsulitis

OBJECTIVE

Adhesive capsulitis (AC) is a painful shoulder disorder resulting in restrictions of daily activities. Given the recent increase in risk factors for AC, such as diabetes mellitus, research is needed to examine if the incidence of AC has also increased. Therefore, the purpose of this study was to describe the secular trend of AC.

METHODS

Subjects were from The Health Improvement Network, an electronic medical record database of general practices across the UK from 1995-2008. General practitioners diagnosed AC. We included subjects ages 40-79 years and defined an incident case as the first diagnosis of AC following at least 1 year of enrollment in the database. We examined the potential independent effects of age, calendar time, and birth cohort using an age-period-cohort model. To approximate effect estimates, we applied proportional hazards models and separately adjusted for diabetes mellitus.

RESULTS

Of 2,188,958 subjects (50.0% women), the incidence of AC was 2.36 and 3.38 per 1,000 person-years for men and women, respectively. Age-period-cohort model graphs suggested a secular trend due to a birth cohort, but not calendar effect. For each 10-year increment in birth cohort, the incidence rate increased by 8% in women (hazard ratio 1.08, 95% confidence interval 1.05-1.13). There was no increase in AC incidence for men. Adjusting for diabetes mellitus did not change these associations materially.

CONCLUSION

We found women born more recently are at a higher risk of developing AC compared with women born earlier. Future research is needed to identify risk factors that may be responsible for this increase.

Absorption of hydrocortisone acetate in human connective tissue using phonophoresis

Background:

Therapeutic ultrasound to drive medication (phonophoresis) has been a mainstay in physical therapy. The most common drug used in phonophoresis is hydrocortisone acetate (HA). A number of studies have been done examining phonophoresis in the delivery of HA through the skin to underlying tissues; however, a study has never been done examining the absorption of HA using phonophoresis on human connective tissue.

Hypothesis:

Phonophoresis will facilitate the transmission of HA in human connective tissue.

Study Design:

Randomized controlled study.

Methods:

Twenty-one patients undergoing anterior cruciate ligament reconstruction surgery were randomly assigned to either a sham or true phonophoresis treatment group. The latter group received 6 minutes of 10% HA ultrasound at a point consistent with the gastrocnemius slip of the semitendinosis tendon (treatment site). The sham group received 6 minutes of 10% HA ultrasound to the same area, but the ultrasound was not turned on. The slip and a sample of the distal attachment of the tendon (control) were removed. Samples were analyzed for HA levels.

Results:

Although the mean and median levels of HA found at the treatment site were greater than those of the control site (means, 34.1 vs 22.9 parts per billion; medians, 7 vs 0 parts per billion), the levels of HA found at the treatment site were not significantly greater than those at the control site (P = 0.15). There were no statistically significant differences between the true and sham phonophoresis groups in HA levels (P = 0.80) nor in age, sex, or skin thickness.

Conclusion:

Phonophoresis does not appear to facilitate the absorption of HA in connective tissue when compared with simple absorption (sham).

Clinical Relevance:

Phonophoresis does not appear to enhance the transmission of HA in human connective tissue; therefore, use of phonophoresis should be reconsidered in inflammatory conditions.
