Abstract:
1. A lower limb prosthesis for replacing a missing lower extremity of an individual, said lower limb prosthesis comprising: a prosthetic foot member; a movable ankle joint member coupled to the prosthetic foot member, the ankle joint member comprising one or more sensors configured to sense one or more parameters associated with the motion of the lower limb prosthesis during ambulation; and a controller configured to receive input data from the one or more sensors corresponding to the one or more sensed parameters, the controller configured to control the operation of the valve to selectively actuate the valve to vary the damping resistance of the ankle joint member based at least in part on the one or more sensed parameters, wherein the movement of the piston results in an adjustment of an angle between the ankle joint member and the prosthetic foot member, thereby altering an orientation of the ankle joint member relative to the prosthetic foot member.
