Study Summary
The purpose of this study is to compare the functional differences between two types of foot prostheses for people with ankle disarticulation (Syme's) amputations. The two feet being tested are low- and high-profile feet, with the difference being the latter has an extended keel and attaches to the posterior of the prosthetic socket, rather than the distal end. The hypothesis is that the high-profile foot (i.e., the crossover foot) will lead to functional and biomechanical improvements compared to low-profile feet.
Primary Outcome
The symmetry between prosthetic and sound side step lengths. Step lengths were calculated as the distance between heels from heel strike of the contralateral foot to heel strike of the ipsilateral foot.
Interventions
- DEVICE Crossover foot
- DEVICE Energy Storing Foot
