The load on the hip joint during exercise was calculated and analyzed using integrated EMG and their muscle force of the contraction and co-contraction. 20 lower extremities of 10 healthy males were used for this study. The exercise, such as straight leg rising (SLR), hip abduction, and knee extension, were picked out for this study. The integrated EMG (%MVC) and the muscle force of the contraction and the co-contraction were measured using Cybex 6000. The mathematical model was used to analyze the load on the hip joint in each exercise. In SLR, resultant force on the hip joint was 908 N and 1.4 times body weight at 10 hip flexion, and it was decreased with increasing hip flexion. In the hip abduction on the lateral position, it was 1.8 times body weight at 10 degrees hip abduction, and it was decreased with increasing hip abduction. In the knee extension with sitting, it was 127N at 60 degrees knee flexion angle, and it was increased with knee extension gradually. The analyzed value was equal to that from sensorized prosthesis, and the analyzed method of this study was considered proper evaluation to know the load on the hip joint during exercise.
