In the context of prosthetics, what does socket sealing help to prevent?

Socket sealing in prosthetics primarily serves to prevent air leaks, ensuring that the prosthetic limb maintains a secure fit against the residual limb. When a socket is well-sealed, it minimizes the gap between the prosthetic and the limb, which helps to maintain a vacuum effect. This vacuum is crucial for providing stability and reducing movement within the socket while the user engages in various activities.

A proper seal not only helps in preventing air from getting into the socket but also plays a role in enhancing the comfort and function of the prosthesis. Maintaining a good seal can lead to better suction and improved control over the prosthesis, ultimately contributing to a more effective alignment during walking and other movements. In contrast, insufficient sealing can lead to discomfort, instability, and even skin conditions due to the frequent shifting of the socket and the potential for friction against the skin.
