Primary | Assess compliance of residual limb in the socket, which will improve the fit and comfort of the prosthesis. | We will measure the compliance of their residual limb by the displacement of the socket wall relative to the femur under mechanical loading with X-ray. The subjects will adjust their foot placement, limb loading and muscle contractions to achieve up to 8 specified force/torque levels (as measured by a 6 degree-of-freedom load cell located in series with their pylon and socket), which correspond to forces and torques that are typical of over ground walking and standing postures and are scaled for their body weight. For each force/torque level, static X-ray scans of locations of the prosthetic socket wall and residual limb femur will be acquired. | Pre surgery and 6 months post surgery | |
Secondary | Assess walking endurance | Complete 6 minute walk test over level ground as metabolic energy consumption and heart rate our monitored. Subjects may wear a portable, commercially available metabolic measurement system so that their metabolic energy expenditure may be calculated after the experiment. | Pre surgery and 6 months post surgery | |
Secondary | Assess balance stability | Complete the 4 square step test as a clinical test of the ability to change directions while stepping. | Pre surgery and 6 months post surgery |
