The aim of this study is to evaluate the muscle activity of each muscle by integrated electromyogram (iEMG) signal in daily life. We have measured the iEMG signals from the medial vastus muscle, the semitendinosus muscle, the rectus femoris muscle, and the biceps femoris muscle. The muscle activity was calculated using iEMG signals. The muscle activity was evaluated by comparing the muscle activity in daily life to the activities of muscle in level walk of 10 steps. We compared the evaluation results of the muscle activity for each muscle. From these results, it has been proved that the muscle activity is different even if these muscles belong to the same group, which exerts the same action on one joint. This result suggests that the evaluation of each muscle activity should be useful for safety and efficient training of rehabilitation. © 2005 Wiley Periodicals, Inc.
