INTRODUCTION Among amputees, the most commonly reported problem affecting daily quality-of-life is excessive sweating1,2. Some studies report that as many as seven out of ten amputees are affected1,3. Compared to able-bodied people, trans-tibial amputees expend up to 40% more energy during every-day activities, which contributes to excess perspiration4. Particularly common is localised sweating on the residual limb. This could be due to the use prosthetic liners made from non-porous, cushioning materials, such as TPE Gel, Polyurethane or silicones. With these problems in mind, a type of silicone liner has been produced that contains perforations along the length and at the distal end. These perforations permit the warm air to move away from the residuum, allowing better air circulation and, if sweating does occur, the perforations allow moisture to escape. The result is drier, cooler skin and a healthier environment for the residual limb. This study reports prosthetist and patient feedback data from trials of the pin-lock version of these liners.
