Influence of Prosthetic Foot Stiffness on Transtibial Osseointegrated Bone-Anchored Limb Outcomes
University of Colorado, Denver
60 participants
Nov 25, 2025
INTERVENTIONAL
Conditions
Summary
A clinical trial utilizing cross-over study design in which individuals with transtibial amputation using either a bone-anchored limb or standard socket prosthesis will perform activities of daily living with varying prosthetic foot stiffness categories to complete the following 4 Specific Aims: 1) Determine the influence of prosthetic foot stiffness on dynamic bone-implant loading, 2) Determine how prosthetic foot stiffness influences function, pain, and multi-joint biomechanics outcomes, 3) Establish how prosthetic foot stiffness influences osseoperception and fall risk, and 4) Establish target ranges of optimal foot stiffness based on the sensitivity biomechanical outcomes to variability in foot stiffness.

Interventions
Each participant will complete a motion capture collection, tests of physical function, and sensory tests in their currently prescribed prosthetic foot.
Each participant will complete a motion capture collection, tests of physical function, and sensory tests in a prosthetic foot that is two categories stiffer than their currently prescribed prosthetic foot.
Each participant will complete a motion capture collection, tests of physical function, and sensory tests in a prosthetic foot that is two categories softer than their currently prescribed prosthetic foot.
