The principle of isokinetic muscular contraction which has appeared in the scientific literature since 1967 was described and its application to orthopedic clinic was briefly discussed. Isokinetic contraction does mean muscle contraction with constant speed, whereas isotonic contraction means muscle contraction with variable speed. The Cybex isokinetic dynamometer was used to measure quadriceps femoris and hamstring muscle functions in patients with hemiparesis. Comparisons of isokinetic data obtained at 30゜/sec and 180゜/sec were made between the involved and uninvolved side of patients. Bilateral quadriceps femoris and hamstring muscle peak torque, obtained at testing speeds of 30゜/sec and 180゜/sec, was markedly decreased in these patients with hemiparesis compared with the healthy subjects. Patients with hemiparesis were unable to achieve full knee extension on the involved side when performing this test. Timing of both generated torque and reciprocal motion was different as exemplified by prolonged TTRT(time to peak torque), TPTH(time to peak torque is held), and intervals between reciprocal contractions. Patients had even greater difficulty performing the high-speed test than the low-speed test. The results of this study indicate that the Cybex system can provide useful and objective information about altered motor behavior of patients with hemiparesis.
