Isokinetic dinamometry assessment in external and internal rotators of shoulder in impingement syndrome

The goal of this study was evaluate the peak torque and body's relation between the bilateral internal and external rotators and the relation between internal and external rotators of a bearer and non bearer shoulder. Eleven individual, all men, made part of this search. They presented a clinic diagnostic of Unilateral Impingement Syndrome on the dominant member. The evaluation instrument was a PUC-PR Physiotherapy Clinic's isokinetic dinamometer Cybex (R) Norm 7000. The test protocol involved three concentric concentrations by 60 degrees/s, being initially evaluated the non affected side. As a result, peak torque in relation to the body's weight of the non involved side was of 37,98% and 45,93% to external rotators muscle groups and internal rotators respectively. In relation to the involved side, this values were 34,05 to external rotators and 39,24% to internal rotators. When analyzing the relation between external and internal rotators, the obtained values were 0,82 and 0,86 to non involved and involved side respectively.
