A method and system of choosing a prosthetic liner using cross-references databases which informs a user using a specified interface. Specifically, the method comprises a user accessing a graphical interface wherein amputee attributes are entered in order of (1) level of amputation, (2) residual limb length, (3) activity level, (4) residual limb shape/volume, and (5) clinical conditions with corresponding attribute options. Alternatively, the chosen attributes are (1) class of amputation, (2) residual limb length, (3) body weight, (4) use of the prosthesis, (5) activity level, and 6) uneven paths for knee joints with corresponding attribute options. Alternatively, the chosen attributes are (1) level of amputation, (2) residual limb length, (3) body weight, (4) use of the prosthesis, (5) activity level, and 6) uneven paths for foot joints with corresponding attribute options. These amputee attributes are then cross-referenced against one another and compared to a second database containing liners that correspond to the amputee attributes selected thereby educating the user, generally a prosthetist, on the appropriate liner style for a particular amputee.

A magnetic and electrical interface that may be used with an assistive device. The interface comprises a proximal connector and a distal connector. The proximal connector may be attached to a liner for a residual limb and the distal connector may be attached to a hard socket or other aspect of an assistive device. Other aspects of and uses for the connector interface are also disclosed.

An alignment adapter for prosthetic sport feet, such as running feet, includes a male pyramid plate having a male pyramid, a female connector plate having a female connector, and a back plate. For use during alignment of a prosthetic running foot, the male pyramid plate is coupled to the back of a user's socket and the female connector plate and back plate are clamped about the foot. The male pyramid and female connector are coupled and adjusted relative to one another to achieve a desired alignment. The socket and foot are locked in an alignment fixture to maintain the alignment and the male pyramid, female connector, and back plates are removed. A laminated plate is coupled to the socket to maintain alignment during normal use.

A selectively actuated textile includes one or more pieces of fabric having one or more circumferentially constrained channels and one or more hollow elastic tubes located within the circumferentially constrained channels and configured to receive a working fluid. Selectively providing or removing working fluid from the hollow elastic tubes provides for selective actuation of the textile.

A testing apparatus for exposing an associated specimen(s) to motions along multiple axes is provided. The testing apparatus includes a test chamber and first, second, third, and fourth devices that impose different kinematic motions or forces on the specimen. A drive mechanism is connected to the first, second, third, and fourth devices so that motion from a single axis is conveyed by the first, second, third and fourth devices to deliver the desired kinematic motions and/or forces to the test chamber(s). At least one of the first, second, third, and fourth devices includes an adjustment mechanism to modify at least one of the devices.

A prosthetic device includes an elongate support member of carbon filament material having a first surface, and an adapter. The adapter includes a compressible member, a base portion having a contact surface arranged to contact the first surface of the support member, a cavity sized to receive the compressible member, and a connector portion extending from the base portion and configured to releasably secure the prosthetic foot to a prosthesis, wherein application of a force to the connector portion compresses the compressible member to dampen movement of the base portion relative to the support member until the contact surface contacts the first surface.
