Abstract
A method of measuring the performance of a prosthetic foot includes obtaining a pressure distribution of the prosthetic foot during a motion of the prosthetic foot and determining whether the pressure distribution falls within a preselected range of performance values for the prosthetic foot. The pressure distribution comprises a trajectory illustrating the progression of a center of pressure of the prosthetic foot during motion. A prosthetic foot can also be designed to approximate a pressure distribution corresponding to a preselected range of performance values.
Claims21
A method of comparing the performance of prosthetic feet, comprising:
- obtaining a pressure distribution of a first prosthetic foot, said pressure distribution defining a first trajectory;
- obtaining a pressure distribution of a second prosthetic foot, said pressure distribution defining a second trajectory;
- comparing said first trajectory with said second trajectory;
- and
- determining which of said first and second prosthetic feet has a superior performance based on said comparison.
A method of comparing the performance of a prosthetic foot and a human foot, comprising:
- obtaining a pressure distribution of a human foot, said pressure distribution defining a first trajectory;
- obtaining a pressure distribution of a prosthetic foot, said pressure distribution defining a second trajectory;
- comparing said first trajectory with said second trajectory;
- and
- determining a performance rating for the prosthetic foot based on said comparison.
