The objective of this study is to evaluate a test-drive strategy for prosthetic foot prescription using a prosthetic foot emulator PFE to accurately reproduce the experience of wearing several commercially available prosthetic feet. The aims of this research are to 1 determine whether a PFE can be used to predict foot preference and mobility outcomes with corresponding commercial prosthetic feet, and 2 determine whether a brief trial of commercial prosthetic feet would be able to similarly predict longer-term foot preference and mobility outcomes with those feet. During the current reporting period, we have developed and finalized the project protocol manual of operations, study questionnaires and all IRB documents. We have fabricated and delivered the PFE to VA Puget Sound including training of local staff in PFE use. Mechanical testing of commercial study prosthetic feet for input to the PFE is ongoing. Once we receive all necessary IRB approvals, we will begin human subject testing.
