A Prosthetic Foot Test-Drive Strategy for Improving Stability and Falls-Related Outcomes in Veterans with Leg Amputations
Abstract
The objective of this project is to assess the effects of prosthetic feet of varying stiffness on dynamic stability and falls-related outcomes in people with transtibial amputation and to determine whether a test-drive strategy using a multiaxial prosthetic foot emulator can be used to predict stability and balance-confidence outcomes. During this reporting period, we have maintained approval from the VA Central IRB and HRPO for the human subjects portion of the project as well as received additional approvals for IRB amendments to optimized study methodology. We have also performed extensive mechanical testing of commercial prosthetic feet, which is ongoing, but has already informed the development of a multiaxial prosthetic foot emulator that will mimic the sagittal and coronal plane mechanical properties of commercial prosthetic feet without physically changing feet. The multiaxial prosthetic foot emulator hardware is now designed in place at the Seattle site; software is awaiting completion of mechanical testing.
