This work focuses on design and development of a walking aid device for reducing knee adduction moment (KAM) using compliant structure. KAM is defined as a product of frontal ground reaction force and frontal lever arm. It is a major cause of pain at lateral knee which is general symptom of osteoarthritis (OA). For treatment, lateral wedge insole (LWI) was normally used as part of a treatment for OA patients. We therefore designed a device which reduced KAM during walking by shifting the center of pressure (CoP) from medial side to lateral side.
