| Summary: | Gait training for above-knee prosthetic leg user (transfemoral) is needed as a
rehabilitation program to minimize walking disorder and improve walking ability.
The road surface in the real world is not always flat, so it is important to be able
to practice walking in a variety of conditions, including walking on various levels
of slope. One of the technologies that can be used for prosthetic leg user walking
training is VR because it has advantages that it can trigger better gait changes
and increases user’s motivation. However, the current use of VR in walking
training for prosthetic leg user is expensive because it generally uses CAREN (VR
CAVE) and a tilt-changeable treadmill to simulate slope of the road.
This study aims to evaluate whether the use of VR HMD with a high level of
immersion to display visual stimuli in the form of slope level can affect the gait of
prosthetic leg users. Gait is measured based on spatio-temporal and kinematic
parameters. This study was conducted on 6 users of prosthetic leg and 6 normal
people. In general, data processing used repeated measure ANOVA test,
Friedman test, mixed model ANOVA test, Wilcoxon test, and Bonferroni test.
The results showed that the visual stimuli in this study could interfere in changing
the prosthetic leg user’s gait, but the magnitude is not sufficient to change all the
gait parameters. However, because some parameters have p-values close to 0,05,
there could be changes in research results if the experimental design is changed.
There are also some differences in walking strategies between normal people and
prosthetic leg users in different slope levels of road. Therefore, the visual stimuli
displayed on the VR HMD has a great opportunity to be an intervention in the
current training system and make the training more effective.
