简要总结
The investigators are comparing a new type of prosthetic socket for above knee amputees to the standard of care. The hypothesis is that the new type of socket will show equivalence to the standard of care using our designated outcome measures.

结局指标
主要结局
Socket Pressure
时间窗: 10 minutes after fitting with both sockets
Pressure sensors are placed on the skin and measured.
Balance and Stability
时间窗: Based on preliminary experience with the intervention, accommodation can range from 2 weeks to 3 months. Assessment will be scheduled within 2 weeks following accommodation.
Balance and stability will be assessed for limits of stability and postural stability.
Quality of Life
时间窗: Based on preliminary experience with the intervention, accommodation can range from 2 weeks to 3 months. Assessment will be scheduled within 2 weeks following accommodation.
Validated surveys will be used to solicit participants' subjective experience and feedback.
Gait
时间窗: Based on preliminary experience with the intervention, accommodation can range from 2 weeks to 3 months. Assessment will be scheduled within 2 weeks following accommodation.
Gait will be assessed in terms of biomechanics and spatiotemporal parameters.
