초록
This study was designed to develop an objective method of strength measurement ofmuscles controlling the wrist joint in normal subjects. Forty subjects (20 ma1e, 20 female) with a mean age of 22 years, were tested isokinetically at 60 ° /sec and 120 °/sec. Results were as follows, 1) Peak torque for wrist flexors, extensors weresignificantly different for both speeds, but wrist ulnar deviator, radial deviator peak torques were not, 2) Mean values for all muscle groups controlling the wrist were notsignificantly different for both speeds in the female group, 3) All mean values at both60 ° /sec and 120 ° /sec were significantly different between males and females,4)Means and standard deviations of wrist joint angle of movement at peak torque weredetermined.
