研制了一种由健侧踝关节运动控制的踝关节伸展康复装置。物理治疗师治疗他们的病人，以防止受试者踝关节的挛缩和改善他们的行走功能。然而，由于踝关节康复的劳动力需求，无法进行充分的再固定治疗。长期以来一直需要一种自我康复系统来减少所需的劳动量，其中康复系统由物理治疗师使用机器来操作。自我康复尚未实现。通过健侧踝关节的运动来伸展患侧踝关节，就可以开发出可以根据患者意愿使用的自我康复装置。实验证明，该装置可以通过健侧踝关节的角度作为触发器，移动与直线驱动器相连的脚板，实现患侧踝关节的伸展。用两个加速度传感器测量患侧和健侧踝关节旋转角度。健侧控制与以往的按钮推压式控制相比，健侧控制能实现患侧足底推压过程的平稳。所提出的系统，它不需要在治疗过程中由物理治疗师操作，使踝关节的自我康复成为可能。
An ankle joint stretching device controlled by healthy-side ankle movements was developed for self -rehabilitation. Physical therapists treat their patients to prevent a subject ankle joint's contracture and im-prove their walking function. However, sufficient re-habilitation therapy cannot be performed because of the labor demands of ankle joint rehabilitation. There has long been a demand for a self-rehabilitation sys-tem to reduce the amount of labor required, with the rehabilitation system operated by a physical therapist using a machine. Self-rehabilitation has not yet been realized. By stretching the affected ankle through the movement of the ankle on the healthy side, a self -rehabilitation device that can be used according to the will of the patient can be developed. An experiment confirmed that the device can realize affected-side an-kle joint stretching by moving a foot plate connected to a linear actuator using the angle of the healthy-side ankle joint as a trigger. Ankle joint rotation angles of the affected and healthy sides were measured using two acceleration sensors. Compared with the previ-ously used button-push-type control, healthy-side con-trol can realize a smooth and stable affected-side sole -pushing procedure. The proposed system, which does not require operation by a physical therapist during treatment, makes self-rehabilitation of the ankle joint possible.
