What this Trial Is About
The overall goal of this project is to model human joint biomechanics over continuously-varying locomotion to enable adaptive control of powered above-knee prostheses. The central hypothesis of this project is that variable joint impedance can be parameterized by a continuous model based on measurable quantities called phase and task variables. This project will use machine learning to identify variable impedance functions from able-bodied data including joint perturbation responses across the phase/task space to bias the solution toward biological values.

- Cognitive deficits impairing informed consent or ability to follow instructions
- Known allergy to medical grade tape
- Amputee participants weighing over 250 pounds
- Excessively long residual limb length or non-removable cosmetic cover preventing proper prosthesis fitting
