Competitive Advantages:
Improved patient quality of life, Fast and efficient fitting of new devices, Enables development of a smart socket interface.
A device and method for measuring prosthetic or orthotic slip is presented. An optical sensor device is attached to the prosthesis or orthosis and measures the amount of relative motion between the prosthetic socket and the residual limb surface or between the orthosis and the affected body part. The sensor device is comprised of an optical sensor, a light source, a processing unit and a power source contained within a housing. A system for measuring multidirectional prosthetic or orthotic slip using the sensor device and automatically adjusting the fit of the prosthetic based on a determined threshold is also presented.Motivated by the desire to improve device fit and patient quality of life, researchers at USF have invented a prosthesis slip detection sensor to measure and record movement between the limb surface and prosthetic socket or orthotic device. The ability to measure this type of movement enables faster and more accurate fit of prosthetic and orthotic devices for both upper and lower limbs. This invention can be used as an evaluation tool to compare various socket designs or to assist the prosthetist during socket fabrication stages by providing quantitative feedback. The sensor may also be used in the development of a smart socket interface to monitor the amount of movement and adjust socket settings accordingly. This device will open new research possibilities for internal socket dynamics.
