ABSTRACT:
A means and method for tactile stimulus reception for use with a myoelectric prosthesis includes a pressure transducer positioned on the prosthesis. The pressure transducer senses the level of pressure experienced by the gripping portion of the prosthesis and converts the sensed pressure into a corresponding signal. A pressure stimulus member is positionable upon the user and creates a pressure stimulus proportionally corresponding to the sensed pressure of the pressure transducer by utilizing the signal from the pressure transducer. The pressure stimulus is tactile so that the user can be given direct tactile pressure stimulation corresponding directly with the pressure sensed by the pressure transducer.
