Abstract
Disclosed herein are devices, systems, and methods for measuring socket fit in lower limb prostheses and detecting motion of a residual limb relative to a prosthetic socket. Also disclosed herein are methods for developing a socket-fit detection system for sock management that can be applied to adjustable socket systems.
Claims21
A sensor assembly comprising:
- a rigid body defining an opening extending through a thickness of the rigid body;
- a pressure sensor positioned in fluid communication with the opening of the rigid body;
- and
- a membrane positioned in overlying relation to the rigid body,
- wherein the rigid body, a lower surface of the membrane, and the pressure sensor cooperate to define at least a portion of a chamber configured to receive a fluid,
- wherein the membrane has an upper surface that is configured for contact with a distal portion of a residual limb of a patient,
- wherein the sensor assembly is configured for complementary receipt within a distal portion of a prosthetic socket, and
- wherein the sensor is configured to produce an output indicative of changes in pressure within the chamber in response to deformation of the membrane by the distal portion of the residual limb of the patient.
5 more elements
A socket fit management system comprising:
- a prosthetic socket having a distal portion;
- and
- a sensor assembly, wherein the sensor assembly is received within the distal portion of the prosthetic socket.
