Personalized Prosthetic Foot Prescription and Rehabilitation for Veterans With Lower Limb Loss

Study Summary

The goal of clinical trial is to assess an integrated, patient-centered strategy combining user preference-based prosthetic foot prescription and subsequent targeted physical therapy to maximize satisfaction and mobility outcomes for Veterans and others with lower limb loss. The main aims it will address are: * Assess the effect of prosthetic foot selection based on experiential preference as determined using a variable stiffness foot on mobility and satisfaction * Assess the effect of a targeted physical therapy intervention following preference-based foot selection on mobility, balance, and satisfaction? Participants will walk with an emulator prosthetic foot to experience three different conditions that emulate different commercial feet to determine their most- and least-preferred foot. Participants' satisfaction, perceived mobility, and functional mobility will be measured and compared between their most- and least-preferred feet using the corresponding commercial feet. Participants will then be randomly assigned to receive either the standard-of-care (control group) or personalized physical therapy intervention for eight weeks using that preferred prosthetic foot. Participants' satisfaction, mobility, and balance will be measured pre- and post-intervention.

Primary Outcome

Patient-reported outcome measure that assesses functional satisfaction with the prosthesis. The maximum value is 15 and the minimum value is 5, with higher better scores meaning a better outcome. This sum score (max 15) is used for reporting and analysis.
