针对如何避免踝关节损伤患者康复过程中二次损伤,有效地提高康复效果并缩短康复耗时的要求,基于生物医学知识和机构学知识提出以开式串联运动链等效人体足仿生机构模型,把人体足底视为末端件,综合模型的静力分析,将患者在康复过程中的足底受力折算到踝关节坐标系实现踝关节康复受力的间接测量。基于MSP430微处理器设计出一种踝关节康复受力检测系统。该系统测得踝关节康复受力数值作为踝关节康复运动强度的指导性数据,指导患者在康复过程中自主调节康复强度,为保障踝关节安全康复提供技术支持。经临床试用表明,采用该系统能提高踝损伤患者的康复效果,有效缩短康复耗时,降低了二次损伤的概率,具有一定的推广价值。
Aiming at the requirement of avoiding secondary injury during rehabilitation process and improving recovery effect and shortening recovery time effectively in patients with ankle joint injury, based on biomedical and institutional knowledge, The end of human foot as the end piece, the static analysis of the integrated model, the patient during plantar stress in the rehabilitation process converted to the ankle joint coordinate system for indirect measurement of ankle rehabilitation. Based on the MSP430 microprocessor design an ankle rehabilitation stress testing system. The system measures the value of ankle joint rehabilitation force as the guiding data of ankle joint rehabilitation exercise intensity and guides the patients to independently adjust the intensity of rehabilitation in the process of rehabilitation so as to provide technical support for the safe rehabilitation of the ankle joint. The clinical trial shows that using the system can improve the rehabilitation of patients with ankle injury, effectively shortening the recovery time, reducing the probability of secondary injury, with some promotional value.
