Abstract:

The objective of this project is to provide active lower limb amputees who work in demanding environments with a prosthesis and suspension that remains secure despite profuse residual limb perspiration. The specific aims are to 1 Identify the environment and perspiration thresholds at which the current standard-of-care prosthesis fails to provide a secure suspension, and 2 Compare the performance of the current standard-of-care prosthesis with an innovative prosthesis that uses dynamic air exchange to expel accumulated perspiration. During the current reporting period, we have enrolled 5 lower limb amputees into an IRB-approved protocol to walk on a treadmill for up to 30-minutes in a chamber at 20, 30, and 35 degrees Celsius at 50 relative humidity. The cross-over experimental design randomizes the order of the study prostheses. Two subjects have completed the entire protocol. Subject recruitment is on-going.
