The measurement of muscle strength in the hip joint expressed by the octagonal diagram

For grasping hip joint function objectively and planning an adequate program for individual use in rehabilitation during and after the treatment for hip joint impairments, the octagonal diagram of the correct distribution of the hip joint muscle strength will be useful. The muscle strength was measured in the eight directions using the Cybex-II on the U.B.X.T. table not only on the peak torque but also on the maximum work and the maximum work/sec in eighty healthy subjects, forty of each male and female. No difference of the muscle strength between the dominant and the non-dominant legs of both male and female has shown. In the percentage of the values of the muscle strength, there are differences between the peak torque, the maximum work value and the maximum work/sec. The data obtained from this investigation will be available to judge the degree of hip joint impairment, and to make a better therapeutic program for the patients.
