Heat and perspiration discomfort inside prostheses
Skin care of the residual limb is essential for prosthetics wearers, as skin damage greatly affects ability to weight bear. Thermal discomfort inside the socket can occur with as little as 1°C increase in skin temperature.
Most amputees suffer disturbances in all forms of thermal transfer due to socket barrier, decreased surface area of skin / Vascular disease.
Improvements in prosthetic fit, (resulting in better weight bearing,) prevents ventilation and air circulation around the residual limb. Salty sweat can not evaporate and pools, causing irritation. Activity can also cause increases in the skin temperature.
No acceptable solution to this problem has yet been found as most attempts have either secondary side effects.
More than 50% of prosthetics users reported some form of thermal discomfort, regardless of the type of amputation. The writers suggest that this is an area that should receive further research and development than it currently received.
