Background: High string instrument (violin, viola) players are at high risk for developing musculoskeletal problems. In particular, a higher prevalence of shoulder problems has been reported. However, evidence of the effectiveness of therapeutic exercise for musicians with this condition is lacking until now.
Objects: This case series study investigated the effect of a specific exercise program on shoulder pain, dysfunction, and posture of professional orchestral high string musicians.
Methods: Five professional orchestral high string players with shoulder pain participated in this study. A six-week specific exercise program focus on scapular stability for shoulder pain consisted of scapular muscle exercise. Physical examinations for pain and dysfunction, posture were performed, were identified among all subjects before starting the exercise program.
Results: The results revealed that shoulder pain decreased by 67.86% and the effect of pain on instrument play decreased by 63.33%. The shoulder pain and disability Index and the performing arts module-quick disability of the arm, shoulder and hand scale decreased by 71.72% and 51.61% respectively. The exercise program improved function and posture.
Conclusion: A specific exercise program for high string players was effective in managing shoulder pain. This case series is intended to provide empirical data on the effectiveness of an exercise program aimed at assessing the effect of exercise on pain, dysfunction, and posture of professional orchestra musicians associated with specific instrument groups.
