A prosthetic limb test fixture is configured to mimic a human stride. An electronic management system can control the test fixture to follow the position and pattern of a particular selected gait cycle during testing. A proposed prosthesis can be attached to the test fixture. Sensor data collected during testing can be evaluated to determine whether the proposed prosthesis is likely to appropriately fit an amputee patient. Iterative adjustments may be made to the prosthesis based on test data in order to maximize the likelihood of a good fit.

A biomechanical motion device employs a plurality of actuator cylinders to generate forces representative of human gait loading. The biomechanical motion device includes a crosshead that is manipulated vertically by a set of two vertical pneumatic cylinders, and the crosshead is mounted to two vertical shafts on linear bearings that guide the crosshead in the vertical direction. The biomechanical motion device further includes a horizontal slide system that incorporates a linear carriage rail mounted flush to the bottom of the crosshead. The linear carriage rail guides a sliding carriage, and a custom bracket is mounted to the sliding carriage. Attached to the bracket is a pivot shaft and the shaft serves as a simulated knee joint about which a lower leg assembly can be rotated. Horizontal motion colinear with the carriage rail of the simulated knee joint connection is generated using a set of two horizontal pneumatic cylinders. This horizontal motion causes the lower leg assembly to pivot about where a prosthetic foot contacts a bottom contact plate during gait to rotate about the pinned knee joint.

The present disclosure relates to a system for repetitive loading of a prosthetic socket to test the durability of the prosthetic socket. The system includes a base and a load cell coupled to the base. The system further includes a first coupling mechanism positioned vertically above the load cell, and a second coupling mechanism positioned vertically above the first coupling mechanism. The first coupling mechanism is configured to be removably coupled to a first end of the prosthetic socket, and the second coupling mechanism is configured to be removably coupled to a second end of the prosthetic socket. The system further includes a rod having a first end and a second end opposite the first end. The first end of the rod is coupled to the second coupling mechanism. The system further includes a motor coupled to the second end of the rod, a support structure extending vertically from the base, and an actuator coupled to the support structure such that the actuator is positioned vertically above the second coupling mechanism. The system further includes a curved rail coupled to the actuator and positioned between the actuator and the second coupling mechanism. The curved rail is configured to contact the second coupling mechanism along an arc defined by the curved rail such that the second coupling mechanism moves along the arc when the motor moves the rod.
