劳动分工、生活节奏的加快以及疾病等因素使得人体手部神经系统对外界感知灵敏度降低,也导致了中国人体运动障碍的患者数目庞大。针对这类因素导致的手部运动稳定性降低的问题,设计了一套振荡共振辅助系统,对于人体手部运动进行了生理实验研究。该辅助运动系统由多个微电机形成高频振荡源,将不同振动强度的振荡信号作用于手背部。对手部运动的方差和相关时间分析,证明振荡共振辅助系统能够提高手部神经系统的反应灵敏度,增强手部运动的平稳性,为人体医学康复仪器设计和制作提供了很好的生理实验基础。
The division of labor, the fast-paced life, the disease and other factors make the hand of the nervous system to reduce the sensitivity of external perception. Since these factors degrade the stability of human hand movements, the paper designs vibration-resonance aided system, and studies the feasibility of this system in the enhancement of human hand movements. The signal source of the vibration-resonance aided system is generated by several vibration micro-motors that act on the opisthenar with different vibrational intensities. Analysis of variance and correlation time of the autocorrelation function hand movement, we find that the vibration-resonance aided system can improve the responsiveness of the nervous system and improve the stability of human hand movements, which is also meaningful for the design of medical rehabilitation instruments.
