Posterior Shoulder Tightness
Conditions
Brief summary
When the dominant arm is compared with the non-dominant arm in overhead athletes there is a serious internal rotation limitation in the dominant arm. Due to overhead activity, adaptive changes in shoulder joint mobility and flexibility are indicated. Internal rotation limitation is often associated with increased external rotation. One of the reason of this adaptive change is posterior shoulder tightness which is common in overhead athletes as well as in volleyball players. The aim of this study is to determine the effect of stretching program on the range of motion, flexibility of posterior shoulder muscles and functional performance.
