Abstract EN
Background.
The metabolic energy expenditure (MEE) was the most important assessment standard of intelligent prosthetic knee (IPK).
Maximum swing flexion (MSF) angle and gait symmetry (GS) were two control targets representing different developing directions for IPK.
However, the few comparisons based on MEE assessment between the MSF and GS limited the development of the IPK design.
Objectives.
The aim of the present work was to find out the MEE difference of amputees using IPK with control targets of MSF and GS and determine which target was more suitable for the control of IPK based on the MEE assessment.
Methods.
The crossover trial was designed.
Six unilateral transfemoral amputees participated in the study.
The amputees were assessed when wearing the IPK with different control targets, namely, the maximum swing flexion angle and gait symmetry.
The oxygen consumption analysis during walking at different speeds on a treadmill was carried out.
Results.
All subjects showed increased oxygen consumption as walking speed increased.
However, no statistically significant differences were found in oxygen consumption for different control targets.
The ANOVA test showed that the overall effects of the control targets of the prosthetic knee on oxygen consumption were not significant across all walking speeds.
Conclusions.
The control targets of MSF and GS showed no significant differences on MEE in above-knee amputees using IPK.
From perspective of amputee’s metabolic costs, either maximum swing flexion or gait symmetry could be suitable control target for the IPK.
