Mechanical characteristics of ankle foot orthosis and its effect on human gait

摘要

Ankle foot orthosis (AFO) assists the gait motion of persons with disability such as of hemi- plegia, and the biomechanical function is the primary concern of AFO. In conventional prescription of AFO, the attention has been mainly focused on the ankle joint support at a secure position against the stumbing due to toe contact with floor during the swing phase of gait cycle, but little attention has been paid for its function during the stance phase.
