Fundamental Study for the Voluntary Turning-over Motion of the Body Paralysis (NETAKIRI) Patients

功能性电刺激（FES）在身体控制中的应用已被提出用于恢复瘫痪身体的自主翻身运动。FYIG分析是为了考虑FES实现翻身运动的肌肉活动而进行的。采用双极法对正常人翻身过程中的多通道肌电信号进行了测量和分析。结果表明：在翻身过程中，胸腰肌对胸腰扭转起协同作用.由于FYIG信号的瞬态特性，在翻转运动过程中，在这项研究中没有被视为时间的函数。因此，分析是由新的指标翻转运动的进展。它定义为骨盆的旋转角度，能够直观地显示肌肉活动与所需运动的程度.并以上肢作翻身动作时之肌电量测分析翻身动作时之合作活动.对临床应用中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“人机界面”部分进行了改进，使其操作更加方便，本研究结果表明，FES系统用于人体运动控制的基本可行性。这些知识也将适用于加强肌肉作为治疗性电刺激（TES）。

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).
