Repetitive-Motion Shoulder Injuries:
The continual stresses experienced by athletes participating in baseball, football and other throwing-oriented sports place the shoulder at risk for a variety of disorders. These chronic, repetitive stresses can easily strain the delicate balance between mobility and stability which the shoulder requires to function properly.
Differentiating between glenohumeral instability and impingement is a critical step in initiating appropriate nonsurgical interventions. This concise yet comprehensive paper discusses the anatomy and biomechanics of the shoulder, including an evaluation of anterior shoulder pain focusing on the differentiation of very common repetitive-motion injuries. An immediately useful clinical evaluation is followed by treatment options, with specific emphasis placed on nonoperative interventions, including:
*concentrated, supervised rehabilitative programs which focus on rotator-cuff and periscapular strengthening;
*stretching exercises to regain full range of motion, with emphasis on improving internal and external rotation;
*neuromuscular control drills to re-establish timing, coordination, and muscular movement patterns.
*athlete reconditioning by way of sport-specific reintroduction to activities.
