Abstract

A purpose of this study is to obtain design indices for stiffness of Ankle-foot orthosis (AFO) by measuring ankle joint functions of a hemiplegic patient in order to manufacture and prescribe a more suitable AFO for each of hemiplegic patients. The ankle joint functions of 17 hemiplegic patients and stiffness characteristics of their each AFO are measured and correlations between ankle joint functions and stiffness characteristics of AFO are examined. Then, it is found that planter stiffness of AFO has correlations with passive resistive moment of ankle joints in an ankle-neutral and a knee-extended posture and with passive dorsal stiffness of ankle joint in a knee-flexed posture, respectively. Furthermore, in order to examine meanings of these correlations, analyses for gait of a hemiplegic patient with two different AFOs are performed. Results suggest that these two indices for passive properties of ankle joint are possibly valid for estimating stiffness of AFO suitable for each of hemilplegic patients.
