Purpose Exercise of patients was carried out to maintain and improve their body functions. The load on the hip joint during exercise was analyzed using the integrated EMG and force measurement of agonist and antagonist muscles. Method Experiment 1: The relationship between the integrated EMG and the muscle force of hip abduction was examined to identify their linearity up to 100% MVC using a Cybex 6000. Twelve lower extremities of six healthy males were used. Experiment 2: The load on the hip joint was estimated through this experiment, using twenty lower extremities of ten healthy males. Exercises such as straight leg raising (SLR), hip abduction, and knee extension were performed. The integrated EMG at 100% MVC and the muscle force of agonist and antagonist were measured. Then the integrated EMGs of agonist and antagonist were measured to determine the muscle force in proportion to the force at 100% MVC. Mathematical models were used to analyze the load on the hip joint in each exercise. Results Experiment 1: The integrated EMG and the muscle force of the hip abduction showed a strong linearity up to 100% MVC. Experiment 2: In SLR, the resultant force on the hip joint was 908 N and 1.4 times body weight at 10 degrees hip flexion. It was 765 N and 1.2 times body weight at 20 degrees, and 657 N and equal to body weight at 30 degrees. In hip abduction in the lateral position, it was 1.8 times body weight at 10 degrees hip abduction, and it decreased with increasing hip abduction. In knee extension with sitting, it was 127 N and 0.2 times body weight at a 60-degree knee flexion angle, and it increased gradually with knee extension. Conclusion The analyzed values showed good agreement with those from sensorized prostheses. The proposed method in this study was considered appropriate for evaluating the load on the hip joint during exercise. In SLR, the load was 1.4 times body weight, which was unexpected. Our approach will be applicable to other exercises in a rehabilitation protocol.

下肢外傷により,治療上患側下肢免荷を余儀なくされた入院患者20 名,平均年齢39.2(20~61)歳を対象とし,DXA法を用いて大腿骨頸部,転子部の骨密度を測定し,健側骨密度に対する免荷側骨密度の低下率を用いて,免荷による骨萎縮率の評価を行った.免荷期間の平均は28.8(7~82)日で,大腿骨頸部の平均骨萎縮率4.9 %,大腿骨転子部は平均3.5 %であった.大腿骨頸部の骨萎縮率と完全免荷期間との相関係数は0.50(p <0.05),同じく大腿骨転子部では0.63(p<0.01)で,回帰直線の傾きは,大腿骨頸部では0.09,大腿骨転子部では0.13と,大腿骨近位部は免荷により1 日で約0.1 %の骨萎縮を来たしていた.
