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.

从仰卧到坐姿坐起来的能力对身体独立很重要。我们一直在研究利用功能性电刺激(FES)恢复运动功能。仰卧起坐活动的重建是直立起立运动的难点之一，本研究的第一个目的是阐明健康受试者仰卧起坐时的肌肉活动和运动模式。二是探索FFS重建坐姿的可能性。我们重点研究了从仰卧到长坐的坐姿模式，即通过右肘位置从仰卧起立到长坐。8名年轻男性志愿者参与了这项研究。我们用表面电极同时观察了18块肌肉，包括颈部肌肉、躯干肌肉和上肢肌肉。用运动分析仪测量仰卧起坐时的运动学数据，确定仰卧起坐时的运动模式。根据运动分析仪和肌电的数据，可以将仰卧起坐的运动模式分为…更多的ee阶段。第一阶段是从开始位置到右肩带从支撑面抬起。第二阶段至肘位，第三阶段至长坐位。在第一阶段的开始阶段，胸锁乳突肌的活动先于其他肌肉的活动，以屈曲和旋转头部。双侧腹直肌活动逐渐增强，在第二时相早期达到高峰。第二阶段左侧外斜肌活动高于右侧，躯干向右侧屈曲和旋转。左侧前锯肌在第一时相动作早于右侧，将左侧肩带从支撑面上抬起，瘫痪侧前锯肌似乎是恢复患者坐位活动的重要肌肉。然而，从健康受试者对前锯肌进行电刺激的尝试结果来看，对前锯肌进行有效的电刺激还需要解决电极的位置、电极的大小、刺激强度等问题。较少
