Abstract

A disturbance in scapulothoracic kinematics can cause negative biomechanic effects on the upper extremity function. Alteration in scapular function can be the factor for upper extremity injuries. Purpose of this study was to know the effectiveness of scapular muscle strengthening in overhead athletes in decreasing the incidence of upper extremity injuries. A section of exercises aiming for the activation and strengthening of scapular muscles was included in the daily regime of overhead athletes. Stretching exercises were prescribed to balance the shoulder mobility. Overhead sports included in this study are badminton, handball, volleyball and javelins throw. 94 elite athletes of the Andhra Pradesh state academy were included in this study. Training hours varies for each sport; rate of incidence of upper extremity injuries is calculated per 1000 hours. Incidence of injuries has reduced significantly after inclusion of scapular strengthening program. This data signifies the importance of scapular kinematics and muscle balance in upper extremity function and encourages those caring for overhead athletes to include exercises for restoration of scapular muscle balance as an essential part of athletic training.
