项目摘要

In this research, development of the rehabilitation system with force display function and its control system for grip-disabled person was performed. This system consists of combination of DC motor, a gear slowdown machine, a rotary encoder and the personal computer for measurement/control, etc. The pressurized force and the total grip force of each finger (five fingers) can be directed as torque by the DC motor. It has following features : (1)The grip force is changed to torque by gripping the lever, and load torque is given arbitrarily to the axis attached the lever as the reaction force of the motor. (2)Not only the total torque but also the pressurization force of each finger (five fingers) can be measured by using small compression type load cells. (3)A rotary encoder detects the grip angle of a lever, and (4)CG picture changes corresponding to the grip angle gives motivation and pleasure instead of boring rehabilitation. (5)The situation (muscle fatigue) of a grip fall of a healt … More hy person can be measured too using this equipment. Doctors, occupational therapists, the experimental subjects at the Rehabilitation Center of Kansai Medical University Medical School Hospital were investigated for the opinion about the user-friendliness and the function of this rehabilitation system. Evaluation of being able to perform adjustment of reaction force freely was obtained. Following negative opinions about the rehabilitation system, however, were also obtained through the questionnaire. (1)The device is too large in size and too expensive. (2)Lever gripping cannot be necessary. (3)The device lacks in user-friendliness. (4)The device has too strong image as a machine. (5)CG does not have enough have impact to the experimental subjects. Consequently, priority was given over improvement of this equipment to development of the grip rehabilitation system gentle to a patient, and the prototype model of rehabilitation system using air pressure was completed as the collaboration stuck to the medical spot with the doctor of this rehabilitation center. The newly developed rehabilitation system consists of two flexible balls, pumps, a pressure gauge, an A/D converter, a note PC, etc. It has been received extremely good reaction from patients and occupational therapists, and the data of a patient's grip can also be collected and recorded now by the new system.

本研究开发了具有力显示功能的握力障碍者康复系统及其控制系统，该系统由直流电机、齿轮减速机、旋转编码器和用于测量/控制的个人计算机组合而成。等。每个手指（五个手指）的加压力和总握力可以通过直流电机直接转化为扭矩它具有以下特点：（1）通过握紧杠杆将握力转换为扭矩，并施加负载。扭矩任意赋予附加轴(2)使用小型压缩式称重传感器，不仅可以测量总扭矩，还可以测量每个手指（五个手指）的加压力。 (3)旋转编码器检测握力。 (4)与握把角度相对应的 CG 图像变化提供动力和乐趣，而不是枯燥的康复 (5)也可以测量握把身体下降的情况（肌肉疲劳）。使用该设备。关西医科大学医学院附属医院的康复中心的治疗师和实验对象对该康复系统的用户友好性和功能进行了调查，获得了是否能够自由调节反作用力的评价。然而，通过问卷调查也获得了有关康复系统的意见：(1)该装置尺寸太大并且太昂贵(2)该装置缺乏用户友好性4。 )设备太强(5)CG对所检查的实验对象没有足够的影响，优先考虑开发对患者温和的握力康复系统，以及使用该康复系统的原型模型。与该康复中心的医生合作，在医疗现场完成了气压测量。新开发的康复系统由两个柔性球、泵、压力表、A/D转换器、笔记本电脑等组成。得到了患者和职业治疗师极好的反响，数据新系统现在还可以收集和记录患者握力的情况。
