Abstract

Background: The aim of this study was to assess the isokinetic measures of surgically repaired ruptures of the pectoralis major muscle in contrast to non-injured side of the patients and specify the most affected movement of the injured side.Methods: Nine pectoralis major muscle tears in nine patients were studied.They were all operated by the same surgeon and after 2.4 years (1-4 years) of follow up they were clinically examined. They completed a standard questionair and isokinetic dynamometry were carried out bilaterally. There was also a group of six non-injured bodybuilders who were assessed by isokinetic dynamometry to give us normal differences in the values of both limbs.Results: In the patient group, the mean torque of flexion was not different between the injured and uninjured sides (p < /em>≥.05). For the extension movements, the difference was significant (p < /em>
