Summary

This study tested three different types of lower-leg prostheses to see which one best handles sweat and stays secure in hot, humid conditions. Twenty people with below-knee amputations wore each prosthesis for two weeks during daily activities and then walked on a treadmill in a hot room. The goal was to find a design that reduces skin problems and improves comfort for active amputees.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: prosthetic suspension systems (standard, perforated liner, and air-exchange pump device)
What this could lead to: If successful, this could point toward better prosthetic designs that keep limbs secure and healthy in hot, sweaty conditions.
What could go wrong: This is a small, completed study with only 20 participants, so results may not apply to all amputees. The devices may not work as well in real-world settings beyond the lab.
