Scientists probe why prosthetic limbs feel too hot or cold

This study aimed to understand how people with leg amputations sense warm and cool temperatures on their skin and how their blood flow changes in response. Researchers tested 56 people, including those with and without diabetes and with and without amputations, by gently warming or cooling a patch of skin on the leg. The goal was to gather basic knowledge about how amputation and diabetes affect the body's natural temperature regulation, which could inform future designs for more comfortable prosthetics.
