The Effects of a Powered Knee Orthosis on Gait Kinematics of Children With Knee Extension Deficiency

The Agilik is a leg orthosis device supporting the knee joint, and is intended to be worn on one or both the legs. The device is customized for single patient use. It is composed of custom-fabricated polypropylene leg shells (thigh, calf and foot components) with joint supports, actuator, sensors, cabling and a battery waist pack. The Agilik is attached to the patient using straps - two on the thigh and two on the shank. A rotational linkage connects the thigh and calf portions of the device, is placed lateral to the knee joint, and is aligned with the knee center of rotation.
