概要

We developed a prototype system for stretching the "posterior lower limb (flexor) muscles" by automatically dorsi- and plantar-flexing the ankle joint in smooth motion at slow and steady speed. We confirmed that dynamically stretching the "triceps surae" increases the blood flow from muscle pumping effect. This demonstrates that the system is effective for preventing Venous Thrombosis, in addition to the function as a stretcher (which is effective for preventing articular contracture). The responding torque for stretching the ankle joint is measured to assess the flexibility of the joint, and its variation in time series are quantitatively traceable for estimating the exercise record. The balancing capability at standing posture is also simultaneously evaluated from the torque variation.
