Abstract
A method of sensing ground contact with a lower limb prosthetic or orthotic device is provided. A first translational displacement between a frame and a connector can be sensed and then processed to identify an axial load caused by heel-ground contact. Additionally, a second translational displacement between the frame and the connector can be sensed and then processed to identify a torsional load caused by toe-ground contact.
