摘要：Our concern in this study is to ascertain the difference in plantar flexor strength between the injured and uninjured sides of the patients receiving surgical repair of the Achilles tendon rupture. Subjects consisted of 16 male patients who had received the surgery more than one year before. They performed both isometric and isokinetic movements and their plantar flexor strength was measured by the Cybex II+ isokinetic dynamometer. The average plantar flexor strength of injured side was found to be lower than that of uninjured side. The percentages of the strength of injured side were 75-88% and 85-92% of that uninjured side during isometric and isokinetic movements, respectively. Some subjects, however, showed higher muscle strength in injured side than in uninjured side, which implies that recovery of muscle strength may be dependent on postoperative treatment or therapy.
