The repetitive micro traumatic stresses placed on the athletes shoulder joint complex during the throwing motion challenge the surrounding tissues. The purpose of this study was to compare shoulder rotational strength, range of motion and proprioception between the throwing athletes and non-athletic persons.
Fifteen throwing athletes and 15 non-athletes participated in a nonrandom case control study. Strength of shoulder rotational movements was tested with a hand held dynamometer. The ranges of internal and external rotation of shoulder were measured by a standard goniometer. The ability of subjects to replicate the target position and kinesthetic sense was examined on the subjects right shoulder by using a continuous passive motion device. Independent and paired t tests were used to statistically analyze between and within group differences.
No significant difference was detected on the range of internal rotation between throwing athletes and non-athletic candidates (
The repetitive nature of overhead throwing and the high forces that it causes result in adaptive changes of the dominant extremity. Throwing can lead to mobility, strength and neural adaptation.
