Dynamic testing system for evaluation of the mechanical integrity of prosthetic sockets

Dermatological problems of amputees due to excessive heat generation within the prosthetic socket can lead to ulcers, cysts, sores, infections, and tumors. Approximately two-thirds of those suffering from dermatological problems are lower limb amputees. Currently there is research into developing new prosthetic socket designs with lighter or ventilated material to alleviate these problems. However, these designs have to be tested to ensure the amputee can rely on the device to be mechanically sound. The proposed dynamic gait simulator is designed to measure prosthetic socket strain distribution for a range of ground reaction forces and gait velocities so that mechanical integrity of these new designs can be evaluated, as well as assist training of new prosthetists in socket design.
