Effect of scapula stability exercises on muscle power and functional performance among scapular dyskinesia individuals

Introduction: Scapular dyskinesia, an alteration in scapular position and movement, can lead to decreased muscle power and impaired shoulder function. Objective: The objective of this research was to assess the effect of scapula stability exercises on muscle power and functional performance in scapular dyskinesia individuals using a Seated medicine ball throw and the DASH questionnaire. Methodology: A closed-envelope experimental study was conducted with 32 participants assigned to the scapula stability exercise group (n = 16) and scapular mobilization group (n = 16). Results: The scapula stability exercise group showed statistically significant improvements in all measured outcomes. SMBT score improved from 1.60 ± 0.20 to 3.95 ± 0.35 (p < 0.001). DASH score decreased from 39.68 ± 5.32 to 20.51 ± 3.76 (p < 0.001), indicating improvement in both muscle power and functional performance. Discussion: Our study shows significant improvement in scapular dyskinesis when treated with scapular stability exercises for 6 weeks, thereby indicating that stabilization exercises can improve scapular kinematics. Conclusions: The result supports incorporating scapular stability exercises into rehabilitation programs to improve muscle power and functional performance in individuals with scapular dyskinesia.
