Objectives: Scapular-focused exercises are included in the rehabilitation of people with scapular dyskinesis (SD); yet, there is a noteworthy level of ambiguity concerning the comparative efficacy of different interventions in terms of their ability to enhance shoulder discomfort and function. This research analyzed the impact of a scapular-focused exercise schedule on shoulder pain and function of patients with scapular dyskinesia.
Methods: PubMed, Medline (Ovid), Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro), Google Scholar, and Scopus databases were explored up until July 2021 for randomized controlled trials (RCTs) that considered the impact of scapular-focused training therapy in people with SD. Eleven RCTs, with a combined sample size of 890 participants encountered our inclusion criteria.
Results: The results demonstrated a significant reduction in shoulder pain following exercise (therapy standardized mean difference [SMD]=-0.83; 95% CI, -1.44%, -0.22%; P=0.008). Moreover, exercise therapy significantly improved shoulder function (SMD=-0.62; 95% CI, -1.08%, -0.16%; P=0.008). Nevertheless, scapular-focused exercise had no significant effect on scapula positioning at any angle (0°: Mean difference [MD]=-0.44; 95% CI, -1.43%, 0.55%; P=0.38; 45°: MD=-0.17; 95% CI, -0.72%, 0.37%; P=0.53; 90°: MD=-0.25; 95% CI, -1.06%, 0.57%; P=0.56).
Discussion: Scapular-based exercise therapies are effective approaches among patients with SD. It is necessary to conduct additional high-quality studies with longer periods to evaluate and validate the results reported in this study.

• The optimal functioning of the shoulder joint is highly dependent on the positioning and movement of the scapula.
• Scapular dyskinesis reduces the stability of the shoulder joint.
• Scapula-based exercises effectively improve shoulder pain and function.
• Scapula-based exercise did not demonstrate a significant impact on scapula positioning.
Plain Language Summary
Appropriate functioning of the shoulder joint is dependent on the positioning and movement of the scapula, such as facilitating shoulder repeated motions. The scapular as a multi-task component and a base for muscle attachments implements numerous functions donating to the mobility and stability of the shoulder girdle. Scapular static and dynamic alignment assurance the function of muscles related to the scapula complex and prevent some disorders and shoulder pains. It is suggested that the glenohumeral joint’s function becomes efficient if the stabilizing role of the scapula is normal, and the function of the neuromuscular system is improved.
