Abstract

Rehabilitation exercises which maintain a patient's interest and quantitative evaluation of rehabilitation are required. To solve these problems, we have developed a haptic device system. This system consists of a haptic device, a display, a computer, and software for a training program. When users move the grip, the haptic device provides a virtual force, either assisting the movement of their arm or working against it. To investigate the functional effect of this system using a training program, we measured the grip position, velocity, force on the grip, and electromyographic (EMG) activities during a reaching task for five healthy subjects. Spatio-temporal patterns of both the velocity and grip force, the accuracy of the grip trajectories, and the EMG patterns were similar in all subjects. These results suggested that the EMG activities were improved by applying the virtual force to the grip. These results can be used for the development of rehabilitation training programs and evaluation methods.

触觉装置系统用于上肢康复的基础实验
康复练习需要保持病人的兴趣和对康复的定量评估。为了解决这些问题,我们开发了一种触觉装置系统。该系统由触觉装置、显示器、计算机和培训程序软件组成。当用户移动手柄时,触觉设备会提供一种虚拟的力量,要么帮助他们的手臂运动,要么反对它。为了研究该系统在训练过程中的功能效果,我们测量了5名健康受试者在伸手任务中的握力位置、速度、握力和肌电图(EMG)活动。速度和握力的时空格局、握力轨迹的准确性和肌电图在所有被试中都是相似的。这些结果表明,通过对握把施加虚拟力,肌电活动得到改善。这些结果可用于制定康复训练方案和评估方法。
