The present disclosure provides a method of reducing phantom limb pain or diabetic neuropathy pain, and increasing prosthetic control, by stimulating dorsal spinal rootlets and/or lateral spinal cord adjacent to the dorsal rootlets, of sensory neurons innervating the limb with the phantom limb pain or diabetic neuropathy pain, or the prosthetic.

A prosthetic foot includes a spring component and a sole component. The spring component comprises two or more stacked beam elements, each beam element including, along the length of the respective beam element, a first portion and a second portion, and the second portion of the beam element includes an extent with a length-varying width. The respective beam elements are fixed to each other and to the sole component proximate the heel portion of the sole component or the toe portion of the sole component at the first portions of the respective beam elements to form a fixed end of a cantilevered composite beam. The second portions of the respective beam elements are laterally movable with respect to each other when the spring component deflects.

A joint for a prosthesis comprises a prosthesis part and a body part. The two parts are connected by a connection part. A first pair of engaging sets of abutments is provided on the connection part and the prosthesis part and a second pair of engaging sets of abutments is provided on the connection art and the body part. By adjusting position of the connection part, the first pair of sets are disengageable and by further adjusting the position, the second pair of sets are also disengageable. This allows for adjustment of the joint at two levels. A prosthesis includes two stripes of resilient material of which at least one has a curved part and a straight part. The joint is provided at a distal end, at the concave part of the strips. At straight parts, the strips cross and one strip extends beyond the other.

A prosthetic foot is provided with a forefoot spring, a heel spring and a base spring. The base spring is connected to the heel spring and to the forefoot spring. The base spring has receiving means for the forefoot spring and the heel spring, into which receiving means the heel spring and the forefoot spring can be inserted. The heel spring is connected to the forefoot spring via a coupling element, and the coupling element extends forwards along the forefoot spring at least via one portion thereof.

Prosthetic feet that provide for variable and adjustable stiffness are provided. A foot element can include a tongue portion defined or formed by a slot in the foot element that at least partially separates the tongue portion from a remainder of the foot element. The tongue portion can be operably connected to the remainder of the foot member to increase the stiffness of the foot member or operably disconnected from the remainder of the foot member to increase the flexibility of the foot member. The prosthetic foot further includes a mechanism for adjusting whether the tongue portion is operably connected or disconnected from the remainder of the foot member. The mechanism can be selectively actuated to adjust the stiffness of the foot element in dorsiflexion and/or plantarflexion and/or to adjust the degree to which the tongue portion is allowed to flex relative to the remainder of the foot member.

A prosthetic foot having a base spring having a toe end portion and a heel end portion, and a top spring assembly. The top spring assembly includes a first spring member having a distal end and a proximal end, a second spring member spaced apart from the first spring member along substantially an entire length of the first spring member, the second spring member having a distal end and a proximal end, a first bond connection provided between the distal ends of the first and second spring members, a second bond connection provided between the distal end of the second spring member and a top surface of the base spring in a forefoot portion of the base spring, and a spring connector extending through at least a first hole formed in the base spring, the second bond connection and the second spring member.

A powered leg prosthesis including a powered knee joint with a knee joint and a knee motor unit for delivering power to the knee joint, a powered ankle joint coupled to the knee joint including an ankle joint and an ankle motor unit to deliver power to the ankle joint, a prosthetic foot coupled to the ankle joint, a plurality of sensors for measuring a real-time input, and controller for controlling movement of the prosthesis based on the real-time input. In the powered leg prosthesis, at least one of the knee motor unit or the ankle motor unit includes at least one drive stage, where the drive stage includes a rotary element for generating torque and at least one looped element affixed around the rotary element and configured for transmitting the torque to another rotary element coupled to a joint to be actuated.

Prosthetic feet that provide for variable and adjustable stiffness are provided. A foot element can include a tongue portion defined or formed by a slot in the foot element that at least partially separates the tongue portion from a remainder of the foot element. The tongue portion can be operably connected to the remainder of the foot member to increase the stiffness of the foot member or operably disconnected from the remainder of the foot member to increase the flexibility of the foot member. The prosthetic foot further includes a mechanism for adjusting whether the tongue portion is operably connected or disconnected from the remainder of the foot member. The mechanism can be selectively actuated to adjust the stiffness of the foot element in dorsiflexion and/or plantarflexion and/or to adjust the degree to which the tongue portion is allowed to flex relative to the remainder of the foot member.

An attachment system for use with a prosthetic device includes a first component including a first surface, and further including one of a channel and a projection disposed on an opposite side of the first component than the first surface. A second component including a second surface, and including the other of the channel and the projection disposed on an opposite side of the second component than the second surface, the other slidably engaging the channel or the projection to selectively couple the first component and the second component together. One of the first surface and the second surface is operable to be attached to the prosthetic device, and the other is operable to be attached to a sole structure having a ground-engaging surface.

A lower limb prosthetic device for use when bathing and showering includes a first shell. A rod is coupled to and extends substantially perpendicularly from an upper face of the first shell. A second shell, which has a top that is open, is coupled to and extends from the rod distal from the first shell. The second shell is substantially complementary to and configured to insert a stump of an amputated leg. A plurality of bladders, which is selectively inflatable, is coupled to an inner surface of the second shell. The bladders are configured to be inflated to couple the second shell to the stump. A plurality of first holes and a plurality of second holes are positioned through the first shell and the second shell, respectively. The first holes and the second holes are configured to drain water from the first shell and the second shell, respectively.
