Basic science and clinical application in the athlete's shoulder. A preventative program focusing on the glenohumeral joint.

This program can be implemented as either a preventative program or a rehabilitative program for the upper extremity in the throwing athlete or in nonthrowing athletes involved in overhead activities. The authors have found this program to be easily employed in a university setting. The keystone to its effectiveness is the participating individual. For optimal results, it should be performed as specifically outlined. The likelihood that shoulder symptomatology will develop is higher now that more people are participating in recreational and team sports for cardiovascular fitness. It is, therefore, imperative that a preventative program be developed in both the recreational and professional athletic population.
