Question: 1 / 400

How can a sleeve improve the performance of a prosthetic device?

By increasing heat retention

By minimizing pistoning

A sleeve improves the performance of a prosthetic device primarily by minimizing pistoning. Pistoning refers to the phenomenon where the residual limb moves up and down within the prosthetic socket during movement, which can lead to discomfort, instability, and reduced control of the device. A well-designed sleeve creates a more secure fit by providing additional friction and support, thereby reducing the space between the limb and the socket. This stabilization enhances the overall functionality and comfort of the prosthesis, allowing for a more effective transfer of forces and movements during activities such as walking or running. By minimizing pistoning, the sleeve can significantly improve the user's experience and confidence in their prosthetic device.
