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.
