The Application of Functional Electrical Stimulation(FES)to the body control has been proposed for the restoration of the voluntary turning-over motion of the paralyzed body.1. FYIG analysis was performed in order to consider muscle activities for the realization of the turning-over motion by FES. Multichannel EMG signals of normal subjects during the turning-over motion were measured by the bipolar method and analyzed. The results indicated that the muscles in the thoracolumber part seemed to act the synergetic role for the twisting of the chest and the waist during the turning-over motion.2. Because of the transient characteristics, the FYIG signals during the turning-over motion were not treated as a function of time in this study. Hence, the analysis was performed by the new index ior the progress of the turning-over motion. It was defined as the rotation angle of the pelvis, and able to show the muscle activities with the degree of the desired motion directly.3. EMG measurements were also performed to analyze the cooperative activities during the turning-over motion in a case where an upper extremity was used.4. The FES system which is used for the restoration of the motor functions in high spinal cord injury patients in the clinical application was improved, especially the part of the "patient-machine interface" for the ease of operation.The results of this study suggest the fundamental feasibility of the control of the body movement by means of FES. The knowledge will be also applicable to the strengthening the muscles as Therapeutic Electrical Stimulation(TES).

功能性电刺激（FES）在身体控制方面的应用已被提出用于恢复瘫痪身体的自主翻身运动。为了考虑FES实现翻转运动的肌肉活动，进行了FYIG分析。采用双极法测量正常人翻身运动时的多通道肌电信号，并对其进行分析。结果表明，在翻身动作中，胸腰部肌肉似乎起着胸腰扭转的协同作用。由于其瞬态特性，本研究未将翻转过程中的FYIG信号作为时间函数来处理。因此，采用新的指标对翻转运动的进程进行了分析。它被定义为骨盆的旋转角度，能够直接显示肌肉活动与期望运动的程度。在上肢被使用的情况下，我们还进行了肌电图测量来分析翻转运动中的合作活动。在临床应用中，对用于高位脊髓损伤患者运动功能恢复的FES系统进行了改进，特别是对“人机接口”部分进行了改进，便于操作。本研究结果表明，利用FES控制人体运动的基本可行性。这些知识也将适用于加强肌肉作为治疗性电刺激（TES）。
