High-intensity stretch treatment for severe postoperative adhesive capsulitis of the shoulder

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.

Effectiveness of Pharmacopuncture Therapy in Adhesive Capsulitis: a Study Protocol for a Pragmatic Randomized Controlled Trial

Background

Adhesive capsulitis is a progressive, idiopathic disorder that significantly impacts individuals̓ daily lives and increases their medical burden. Pharmacopuncture therapy, which combines acupuncture techniques with herbal medicine, involves injecting herbal extracts into specific acupoints. This study aims to determine the effectiveness and safety of pharmacopuncture therapy in comparison to physiotherapy (PT) for treating adhesive capsulitis.

Methods

This research protocol outlines a two-arm, parallel, multi-center, pragmatic randomized controlled trial. Fifty participants will be randomly allocated to either the pharmacopuncture therapy or PT group, and they will receive 12 sessions of their respective therapies over a 6-week period. The primary outcome measure is the numeric rating scale for shoulder pain. Secondary outcomes include the visual analog scale score for shoulder pain, Shoulder Pain and Disability Index, Patients̓ Global Impression of Change score, Short Form-12 Health Survey Version 2 score, and EuroQol-5 Dimension. Statistical analysis will be conducted based on the intention-to-treat principle.

Discussion

This trial may offer high-quality and reliable clinical evidence for evaluating the effectiveness and safety of pharmacopuncture therapy compared to PT in the treatment of adhesive capsulitis. Furthermore, this study will serve as a valuable guideline for practitioners when making clinical decisions and managing adhesive capsulitis.

Efficacy of high-intensity home mechanical stretch therapy for treatment of shoulder stiffness: a retrospective review

Background

Shoulder stiffness resulting in motion loss can be caused by numerous conditions, the most common of which is adhesive capsulitis. Surgical intervention is often necessary when conservative methods fail. High-intensity stretch (HIS) treatment may be able to provide increased motion gains while avoiding the cost and complications of surgery.

Objectives

The purpose of this study was to review data from patients who were prescribed a HIS device to recover their shoulder motion to determine the efficacy of the device. The hypotheses were that patients would achieve significant range of motion (ROM) gains and that ROM would increase to a level at which patients would be able to avoid a motion loss surgery and perform activities of daily living.

Methods

Clinical notes were reviewed for patients whose progress plateaued after 4 weeks of therapy and were subsequently prescribed the HIS device after failing to meet their treatment goals. ROM data were recorded for external rotation, abduction, forward flexion, and internal rotation. Pre- and post-treatment ROM data were compared using t-tests.

Results

Significant ROM gains were seen in all planes of motion (p < 0.001). Patients gained an average of 29.9° in external rotation with a last recorded rotation of 59.2°. In abduction, patients gained 40.5° with a last recorded abduction of 123.3°. In forward flexion, patients gained 30.3° with a last recorded flexion of 138.7°. In internal rotation, patients gained 15.2° with a last recorded rotation of 57.6°. These last recorded ranges of motion were sufficient to perform nearly all activities of daily living.

Conclusions

The HIS device was effective in treating patients with shoulder motion loss as demonstrated by the significant ROM gains in all planes of motion. The ability for a patient to recover lost motion quickly without surgery is of great value to quality of life and in healthcare cost savings. We believe this high-intensity stretch device should be considered for use by patients who are at risk for a motion loss surgery.

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.
