Summary

This study compares three different prosthetic liners designed to handle sweating inside an artificial leg. About 180 people with a below-knee amputation who currently have sweat problems will test each liner. The goal is to see which liner helps them feel more stable, secure, and comfortable while sitting, standing, and walking.
