Simulation of the ankle foot orthoses with prevention design for pronation and supination

摘要

Ankle rehabilitation has always been a gap for rehabilitation sciences. This is due to the lack of medical instrumentation and research that covers injuries especially on the supination and pronation effects. Here an extension method for ankle-foot orthoses with preventive design for pronation and supination with ankle dorsiflexion and plantar flexion will be utilized. For the dorsiflexion and plantar flexion mechanism, the proposed system will use the momentum based forward movement with braking system. While for extension design for pronation and supination will be based on hybrid passive and active actuator approach. The extension approach is capable of providing pronation and supination positioning support mechanism. In order to establish the concrete relationship of ankle’s moment a simulation was performed accordingly. This research proved a contemporary methodology of ankle-foot orthoses. It does have significance for ankle rehabilitation sciences
