ABSTRACT
Introduction:
Timely assessment and correction of post-stroke hemiplegia gait, to improve walking ability, has become an urgent problem for patients with hemiplegia.
Objective:
In order to improve the effect of exercise rehabilitation and tensile strength testing, a three-dimensional gait analysis method was proposed.
Methods:
The kinematics, dynamics, ground reaction force and surface EMG of lower limbs were measured by VICON (Nexus 1.8.5), a three-dimensional gait analysis system, and Noraxon, a wireless surface EMG, while 13 healthy subjects walked. The intra-group correlation coefficient (ICC) and standard error of measurement (SEM) were used to compare the relative and absolute reliability of the two test results.
Results:
the re-testability ICC was 78~0.96, the standard error SEM% of kinematics parameters was 4.18~15.6, and the SEM% of dynamic parameters was 3.31~21.82. The SEM% of ground reaction force was 1.70~16.67, and the SEM% of surface EMG signal was 8.00~11.11.
Conclusions:
3D gait analysis can improve the effect of exercise rehabilitation and tensile strength testing, and has good retesting reliability. Level of evidence II; Therapeutic studies - investigation of treatment results.
