Abstract
An illustrative prosthesis and orthosis testing system includes a platform that receives a prosthesis or orthosis. A motor or a weight are configured to apply a load to the prosthesis or orthosis, and one or more load cells are configured to measure a magnitude of the load on the prosthesis or orthosis. The system also includes one or more encoders configured to measure one or more positions and one or more orientations of the prosthesis or orthosis in response to the applied load.
Claims10
A prosthesis and orthosis testing system comprising:
- a platform that receives a prosthesis or orthosis;
- a motor or a weight configured to apply a load to the prosthesis or orthosis through a pylon;
- one or more load cells configured to measure a magnitude of the load on the prosthesis or orthosis;
- one or more encoders configured to measure one or more positions and one or more orientations of the prosthesis or orthosis in response to the applied load, wherein the one or more encoders are configured to calculate a deformation of the prosthesis or orthosis based on the one or more positions and the one or more orientations of the prosthesis or orthosis, and wherein a characteristic of the prosthesis or orthosis is determined based on the deformation;
- and
- a processor in communication with the one or more encoders, wherein the processor is configured to determine a center of pressure location on the prosthesis or orthosis based at least in part on data from the one or more encoders.
