Brief Summary

• Shoulder pain and dysfunction are common problems in overhead sports, due to extreme ranges of motion and repetitive loading. Predisposing factors include inadequate range of motion (ROM), such as a reduction in total ROM or a shift of balance between internal and external rotation. Such a shift may be the result of soft tissue adaptations to the activity demands, or reflect a structural outcome of Humeral retroversion. A shift in the range of motion may be detrimental to the rotator muscle function, which may create another risk factor for shoulder injury.
• The purpose of this study is to document shoulder range of motion, humeral retroversion, rotator muscle strength and fatigue in several groups of overhead athletes undergoing a routine pre season screening once a year, and investigate the interaction between those factors in the different groups.

Outcome Measures

Primary Outcomes (1)

• shoulder internal and external range of motion and resulting total range of motion

  shoulder rotation range of motion will be measured with subject in supine, shoulder and elbow flexed to 90 degrees, forearm in neutral. One assessor will control humeral head motion and slowly rotate forearm into internal rotation, while other investigator will position a bubble inclinometer in line with ulnar shaft and get the reading. Then procedure repeated into external rotation.

  single measurement at season commencmen taken as part of pre- season screening battery. This procedures are routinly administered at the begining of training season of each sport , typically during the first week end training camp.

Secondary Outcomes (3)

• Humeral retroversion

  single measurement, taken as part of pre- season screening battery. This procedures are routinly administered at the begining of training season of each sport , typically during the first week end training camp.

• isometric external and internal rotator strength

  Single measurement, taken as part of pre- season screening battery. This procedures are routinly administered at the begining of training season of each sport , typically during the first week end training camp.

• isokinetic, concentric internal and external rotation, Eccentric internal and external rotation

  single measurement, taken as part of pre- season screening battery. This procedures are routinly administered at the begining of training season of each sport , typically during the first week end training camp.
