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.

在这项研究中，执行了具有力显示功能的康复系统及其针对抓地力的人的控制系统的开发。该系统包括DC电机，齿轮放缓机，旋转编码器和用于测量/控制的个人计算机的组合。加压力和每个手指的总握力（五个手指）可以通过直流电动机作为扭矩。它具有以下特征：（1）通过握住杠杆将握力更改为扭矩，并任意将载荷扭矩作为电动机的反作用力，将载荷扭矩定为连接的轴线。（2）不仅可以通过使用小压缩型负载单元来测量每个手指（五个手指）的总扭矩，而且还可以测量每个手指的压力。（3）旋转编码器检测到杠杆的握力角度，（4）CG图片的变化与握把角度相对应提供动机和愉悦，而不是无聊的康复。（5）健康掉落的情况（肌肉疲劳）也可以使用此设备来测量更多的人。对医生，职业治疗师，Kansai医学院医学院医院康复中心的实验学科进行了调查，以了解有关用户友好性和此康复系统功能的意见。评估能够自由执行反应力调节。然而，在对康复系统的负面看法之后，也通过问卷获得了。（1）设备的尺寸太大，太贵了。（2）杠杆抓地力是不需要的。（3）设备作为机器的图像太强。（5）CG对实验对象没有足够的影响。因此，优先于改进该设备以开发抓地力康复系统对患者的开发，并且随着与该康复中心的医生在医疗位置的合作，使用了气压的康复系统原型模型。新开发的康复系统由两个柔性球，泵，一个压力表，一个A/D转换器，Note PC等组成。它已从患者和占用治疗师那里得到非常好的反应，并且现在还可以收集并记录新系统的患者握把的数据。较少的
