Transfemoral Powered Foot and Physical Therapy Study

Exclusion Criteria

• •Inability to tolerate wearing of a socket or a poorly fitting socket
• •Condition of intact limb prohibits prosthesis use (ulcers, sores, skin breakdown, burns, poor skin coverage, contractures, and severe heterotopic ossification)
• •The length of the residual limb prohibits socket/device fitting
• •Cognitive deficits or a mental health pathology limiting the ability to participate fully in the study or any deficit deemed by the PI to be detrimental to the completion of the study
• •Significant comorbidity, which would interfere with the study (for example: neuropathy, uncontrolled diabetes, receiving dialysis, have insensate feet or severe phantom pain or a history of skin ulcers)
• •Severe circulatory problems including peripheral vascular disease and pitting edema
• •Pregnant women in the 2nd trimester or beyond or women who will be in the 2nd trimester within the enrollment period. This will be determined by asking the participant if she is pregnant or if they believe they may be pregnant. The question will only be asked at inclusion, as biomechanical changes will only be impacted if the woman is in the 2nd or 3rd trimester, and will not be impacted if the participant becomes pregnant while in the study.

• •Use of non-prescribed opioids or over-use of any prescription drugs
