| Outline of Final Research Achievements |
Characteristics of the lower limb intersegmental mechanical energy flow and the quality of muscle activity of patient with hip disease during gait were examined by the 3-D motion analysis system and an EMG frequency analysis using wavelet transform. As a result, the segment torque power of thigh in patient with hip OA was higher than healthy person. This shows that the movement of thigh was large in patient with hip OA, it was suggested that the instability of hip joint was due to the movement of thigh. Also, the mean power frequency (MPF) in the gluteus medius muscle of healthy person was increased in the initial contact of the gait. however, in patient it wasn’t observed. From the above, it was suggested that the instability of thigh may be associated with decrease of the gluteus medius muscle activity.
