项目摘要

Rehabilitation of trunkal motor dysfunction is very important for standing and walking of brain damaged patients. We developed a new "Computerized-Trunk Exercise Assisting System" with which we are repeatedly able to examine or to exercise the trunkal muscle strength and the sitting balance.The examined subject sat on a chair which was equipped with a gravimeter connected to a computer system to track automatically the movements of Center of pressure (COP). The seat was lifted up until the foot was free from the floor. COP was presented on a display in front of the subject. In the task, the subject was asked to lean his body so that his COP arrived the six indicated targets accurately from a home position as fast as possible. This system, in other words, is the examination of the trunkal muscle control function through visual and deep sensorial feedback control. The data of the COP movements were stored and analyzed with respect to range of COP movement, tracking speed and error in each direction.The evaluation was performed in 5 patients with CVD at Kirishima rehabilitation center, Kagoshima University hospital after taking the informed consent of them. The obtained results were shown below.1. This system provides quantitative indices of trunkal muscle balance and is useful for the evaluation of the rehabilitation effects.2. The device can also be used for the exercise of the visually guided trunkal muscle balance and strength.3. The maximal range of lateral COP movement was larger in nonhemiplegic side than that in hemiplegic side.4. After training with system for a week, the range of COP movement tended to be larger and the tracking error was significantly reduced in most of the patients.

躯干运动功能障碍的康复对脑损伤患者的站立和行走非常重要。我们开发了一种新的“计算机化躯干运动辅助系统”，通过它我们可以反复检查或锻炼躯干肌肉力量和坐姿平衡。受试者坐在椅子上，椅子上装有重力仪，重力仪与计算机系统相连，以自动跟踪压力中心（COP）的运动。座位被抬起来，直到脚离开地板。COP被展示在受试者面前的显示屏上。在这项任务中，被试被要求身体倾斜，以便他的COP能尽可能快地从家里准确地到达六个指定的目标。换句话说，这个系统是通过视觉和深度感觉反馈控制来检查躯干肌肉的控制功能。存储了COP运动数据，并对COP运动范围、跟踪速度和各方向误差进行了分析。在鹿儿岛大学附属医院雾岛康复中心对5例心血管疾病患者进行知情同意后进行评估。得到的结果如下所示。该系统提供了躯干肌平衡的定量指标，可用于评价康复效果。该装置还可用于视觉引导躯干肌肉平衡和力量的锻炼。3 .非偏瘫侧COP的最大侧向运动范围大于偏瘫侧COP的最大侧向运动范围。经过一周的系统训练，大多数患者的COP运动范围趋于扩大，跟踪误差明显减小。
