This project explores the idea of improving function of lower limb amputees with a powered prosthesis. While many such devices are currently being developed, it is unclear whether a person can use power from the device to reduce their metabolic effort, or what level of power we should provide the person.  In this study we will monitor people with below-knee amputation as they walk on a treadmill wearing a commercial powered ankle prosthesis where the amount of power supplied and the time of power application can be adjusted in real time.  With this data we hope to determine: 1) if increasing power supplied from a device can incrementally reduce the metabolic cost, and 2) if we can implement an online machine-learning scheme to automatically determine optimal control parameters for each individual.

We are currently recruiting participants with below-knee amputations!
