A prosthetic foot can include an attachment member, at least one first brace, at least one first flexible member, an unpowered actuator, at least one second brace, and at least one second flexible member. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The at least one first brace can mount to the attachment member and the at least one first flexible member can connect to the attachment member by the at least one first brace such that a force between the ground and the attachment member can be supported by the at least one first flexible member. The unpowered actuator can mount to the attachment member and the at least one second brace can be mounted to the actuator. The at least one second flexible member can connect to the attachment member by the at least one second brace such that a force between the ground and the attachment member can be supported by the at least one second flexible member.

Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

A powered prosthetic thigh can have a proximal portion configured to couple to a prosthetic hip socket and can have a distal portion attached to the proximal portion. The distal portion can have a distal connector configured to couple to a prosthetic knee. The powered prosthetic thigh can also have a computer controlled actuator configured to rotate the prosthetic thigh relative to the prosthetic hip socket.

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.
