Abstract: A prosthetic device adapted to be worn on a lower limb of a patient is provided. The prosthetic device includes a socket having an inner surface of which contacts the limb of the patient when the prosthetic device is worn by the patient. Pressure sensors are provided on the inner surface of the socket which measure pressure at the socket-limb interface when the prosthetic device is worn by the patient. The prosthetic device also includes a processor and a wireless transceiver. The processor receives data from the pressure sensors and wirelessly transmits the data to a remote wireless device. A system including the prosthetic device and a remote wireless device is also provided. The remote wireless device can display a map of pressure as a function of sensor location at the socket-limb interface and issue a warning to the patient if the pressure at a sensor location exceeds a specified value. Methods of using the prosthetic to monitor pressure at the socket-limb interface are also provided.
