项目摘要

The ability to sit up from supine to sitting position is important for physical independence. We have been studying to restore motor function using the functional electrical stimulation (FES). The reconstruction of sitting up activity is one of the difficult issues for the FES.The first purpose of this study was to clarify the muscle activity and movement pattern during the sitting up in the healthy subjects. The second was to search a possibility to reconstruct sitting up by means of FFS.We focused on a sitting up pattern that was to get up from supine to long sitting through the right on elbow position. Eight young male volunteers were participated in this study. We have investigated 18 muscles that were neck, trunk and upper extremity muscles simultaneously using surface electrodes. Kinematics data was measured using motion analyzers to determine movement pattern during sitting up.From the data of motion analyzer and EMG, the movement pattern for sitting up could be divided into thr … More ee phases. The first phase was from the starting position to when the right shoulder girdle lifted up from the support surface. The second phase was to the point of on elbow position, and then the third phase was until the long sitting position. The activities of both sternocleidomastoideus muscles were preceded other muscles in the beginning of the first phase to flex and rotate the head. The both rectus abdominis activities were gradually increased and were peaked at early second phase. The activity of left obliquus externus was higher than right side in the second phase to flex and rotate trunk toward right side. The left serratus anterior was acted earlier and higher than the right side in the first phase to protract the left shoulder girdle to lift up from support surface.To restore sitting up activity in patients with hemiplegia, the serratus anterior muscle in paralyzed side was seemed to be important muscle. However, from the results of attempt to electrical stimulation for the serratus anterior in health subjects, effective electrical stimulation for the serratus anterior needed to solve several issues such as location of electrodes, size of electrodes, stimulation intensity and so on.

从仰卧为坐姿的能力对于身体独立性很重要。我们一直在研究使用功能电刺激（FES）恢复运动功能。坐姿活动的重建是FES的困难问题之一。这项研究的第一个目的是阐明坐在健康受试者中的肌肉活动和运动模式。第二个是搜索通过FF重建坐姿的可能性。我们专注于坐着的模式，该模式是从仰卧起到长时间的肘部位置。八名年轻男性志愿者参加了这项研究。我们已经研究了18种颈部，躯干和上肢肌肉的肌肉，简单地使用表面电极。使用运动分析仪测量运动学数据，以确定坐着过程中的运动模式。从运动分析仪和EMG的数据，坐着的运动模式可以分为THR……更多的EE阶段。第一阶段是从起跑位置到右肩女孩从支撑面提起的何时。第二阶段是到肘部位置的点，然后第三阶段是直到较长的坐姿。在第一阶段开始时，两种胸骨骨化肌的活性在其他肌肉之前就弯曲和旋转头部。两种直肠腹部活性逐渐增加，并在第二阶段早期达到峰值。在第二阶段，左斜斜肌的活性比右侧高，以弯曲和旋转躯干向右侧。在第一阶段，左侧塞拉图斯前部的作用早于右侧，以伸长左肩女孩，以从支撑表面抬起。恢复偏瘫患者的坐姿，瘫痪的一侧的腹膜前肌似乎是重要的肌肉。但是，从尝试对健康受试者前部的刺激的尝试结果，对解决几个问题（例如电子的位置，电子的大小，强度等）所需的有效电刺激。较少的
