Understanding Scapulohumeral Periarthritis: A Comprehensive Systematic Review.

BACKGROUND

This systematic review examines the clinical presentations and prevalence of scapulohumeral periarthritis (SP) by synthesizing the relevant literature from open-access articles from international databases (Medline, Pedro, and EBSCO).

METHODS

Keywords guiding the review included 'scapulohumeral periarthritis', 'clinical forms', 'incidence', 'impingement syndrome, 'calcifying tendinitis', 'bicipital tendonitis', 'shoulder bursitis', 'adhesive capsulitis or frozen shoulder', 'rotator cuff tears', 'functional assessment', and 'clinical trials'. Eligible studies included randomized controlled trials, nonrandomized controlled trials, cross-sectional studies, and review articles published between 1972 and 2024.

RESULTS

Our screening identified 2481 initial articles, of which 621 were further reviewed for eligibility resulting in 107 articles that met the relevance criteria. The findings highlight six distinct clinical forms of SP, such as partial rotator cuff tears and calcific tendinitis, each characterized by specific pathological features and prevalence patterns. Key factors contributing to SP include injuries, scapular instability, acromion deformities, and degenerative rotator cuff changes. Functional assessments, including the Neer, Hawkins, Pain Arc, and Yocum tests, demonstrated diagnostic value in distinguishing SP from other shoulder conditions.

CONCLUSIONS

By comprehensively analyzing the clinical forms, functional assessment methods, and prevalent lesions of SP, functional testing can improve early diagnosis and guide personalized physiotherapy protocols for optimal rehabilitation in the physiotherapist's practice.
