Study on Upper-Limb Rehabilitation Training and Evaluation SystemUsing Nano-Particle MR Fluid Actuators

老年人在社会中所占的比例和人数不断增加，他们的身体状况恶化已成为许多国家的一个社会问题。早期发现功能衰退和充分的康复训练是必要的，这不仅可以减少卧床不起或需要护理的老年人的数量，而且可以使老年人积极参与社会。因此，我们研究并开发了上肢康复系统，使用纳米粒子MR流体驱动器。在该系统中，MR致动器用于确保高安全性的目的。磁流变液的流变特性在外加磁场作用下会发生快速而可逆的变化。我们还研究了利用振动作动器和磁流变液制动器的振动促进系统。并对脑卒中患者协同运动的评价装置进行了研究。

The percentage of aged persons in society and their number are increasing, and their physical deterioration has become a social problem in many countries. Early detection of function deterioration and sufficient rehabilitation training are necessary, not only to decrease the numbers of aged who are bedridden or need nursing care, but also to enable the aged to take an active part in society. So, we studied and developed rehabilitation systems for upper limbs using nano-particle MR fluid actuators. In this system, MR actuators were used for the purpose of securing high safety. The rheological properties of MR fluids are rapidly and reversibly altered under an applied magnetic field. We also studied facilitation systems by vibration using vibration actuator and MR fluidbrake. Moreover, we studied the evaluation device of synergy movement in stroke patients.
