Abstract

Shoulder internal and external rotators have been the focus of several isokinetic studies. However, an examination of muscular work in a functional pattern has not been investigated. Therefore, the purpose of this study was twofold: 1) to establish normative ratios of concentric to eccentric work of internal and external shoulder rotators respectively, and 2) to provide information on the balance of strength in shoulder rotators during a simulated throwing pattern.

Twenty-seven subjects without shoulder pathology were tested on the KINCOM isokinetic dynamometer. The statistics for the whole group revealed 55% more concentric internal rotation work in relation to eccentric external work given the range of motions used.

This normative data may help to establish clinical goals in the rehabilitation of overhead athletes.
