A Comparative Assessment of Conventional and Adjustable Transfemoral Prosthetic Sockets
Abstract
The socket is the interface between the human and device and thus integral to the success of any prosthesis. However, one of the most common symptom referred to in a prosthetic clinic is lack of socket comfort. To accommodate for changes in limb volume throughout the day, prosthesis users are instructed to add or remove prosthetic socks for a traditional socket or to adjust the size of the socket using an adjustable socket system. There are several adjustable socket systems that have recently come on the market, including Socket-less Sockets™, Infinite Sockets™, and CJ Sockets™. While implemented differently, each allows the user to adjust the fit of the socket manually while it is worn. Each socket system claims to improve socket comfort and fit, and some also claim to improve mobility and walking endurance. However, as they are so new to the market, there is no objective outcomes research to support these claims. The objective of the proposed work is to enhance understanding of the potential benefits of adjustable sockets and inform clinical decision making. We will explore a range of outcomes that have been found to be important for prostheses and specifically assess the claims made by device manufacturers. Aim 1 will compare socket comfort and prosthetic satisfaction between prosthetic sockets. Aim 2 will determine the impact of prosthetic socket on patient mobility and confidence. Aim 3 will determine if prosthetic socket design influences how the prosthesis is used in the home. Aim 4 will determine patient characteristics that are associated with benefits of specific socket designs. This information can be used to guide prosthetic socket prescription to maximize functional outcomes and quality of life of people with lower-limb amputation.
