This study introduces the Melbourne Instability Shoulder Scale (MISS), a reliable questionnaire for assessing glenohumeral joint instability. Compared to the Shoulder Rating Questionnaire (SRQ), the MISS demonstrated greater sensitivity to clinical changes and a broader range of assessment, offering improved insights for both preoperative and postoperative evaluation.

This study introduces the Posterior Shoulder Instability Questionnaire (PSI-Q), a validated tool for assessing symptoms and function in patients with structural posterior shoulder instability (PSI) requiring surgery. The PSI-Q demonstrates excellent reliability, responsiveness, and internal consistency, outperforming existing measures like MISS and WOSI in capturing patient outcomes.

This study evaluates the outcomes of arthroscopic capsulotomy for frozen shoulder syndrome in 73 patients over a 12-month period. Significant improvements in pain, range of motion, and function were observed, with most patients achieving full recovery within 8.9 weeks. Findings highlight the effectiveness of the procedure while documenting realistic recovery timelines for patients.

This study explores the effectiveness of the Watson Instability Program (WIP1) delivered via telehealth for circus arts performers with atraumatic shoulder instability. Significant improvements were observed in shoulder symptoms, strength, scapular positioning, and handstand stability, highlighting the feasibility of remote rehabilitation during the COVID-19 lockdown.

This study highlights the effectiveness of a 12-week physiotherapy-led exercise program for multidirectional shoulder instability (MDI). Significant improvements were observed in functional status, shoulder muscle strength, and scapular positioning, supporting the value of conservative rehabilitation as a first-line treatment for MDI.

This systematic review examines the effectiveness of exercise-based management for multidirectional instability (MDI) of the glenohumeral joint. Despite some evidence of improved shoulder function, the findings are limited by high bias and variability. The study highlights the need for more rigorous research to validate the benefits of exercise interventions for MDI.
