Abstract

Objective
The aims of this study were to evaluate gait patterns in transtibial amputees with the barefeet relative to the shoe and also to identify the differences between their gait patterns of two different types of prosthetic feet.


Method
An optoelectronic motion analysis of gait was done in six transtibial amputees using both the SACH foot and the single axis foot. In both cases we compared the state of the barefeet with the shod.


Results
The gait abnormalities which were observed during the barefeet gait with the SACH foot showed knee joint hyperextension of 9.9±2.0o and the loss of ankle plantar flexion at the early stance phase. When the single axis foot was used, there was a reduction in knee flexion thrust from 9.9±3.7o to 7.2±3.8o and also in plantar flexion from 9.9±2.8o to 7.0±2.1o during the early stance phase.


Conclusion
There were significant gait abnormalities during the barefoot walking state in transtibial amputees with the SACH foot. We observed that gait patterns have been improved when the single axis prosthetic foot was used.

Key Words: Transtibial amputation, Gait, Barefoot
