Abstract

Children with cerebral palsy (CP) often show excessive knee flexion during walking. To counteract knee flexion, Ankle-Foot Orthoses (AFOs) are frequently prescribed. The effectiveness of AFOs is dependent on their mechanical characteristics, e.g. stiffness [1] and alignment [2]. The Roll-over Shape (RoS) has been proposed as a parameter to quantify the AFO’s mechanical behaviour and alignment [3]. The RoS has however never been investigated in children with CP walking with or without AFOs.
