Abstract
The purpose of this study was to investigate the influence of anterior, posterior, and lateral pelvic tilt exercise upon the gait characteristics of patients with hemiplegia including their gait velocity, cadence, stride length, step length of the non affected side, step length of the affected side, foot angle of the non affected side, foot angle of the affected side, base of support, and so on.
The subject of this study was 24 men and women patients with hemiplegia. The patients, the subject of this study, were classified into 12 patients of treatment group applying pelvic tilt exercise using visual feedback and 12 patients of control group applying general pelvic tilt exercise, and then analyzed their gait before and after exercise. Temporal distance gait analysis (Boening, 1977) was used to analyze tli`Argait, and ink footprint was applied as one of measurement methods.
To find out meaningful difference between control group and treatment group, this study carried out independent sample t-test for each item by utilizing SPSSIWin 10.0, compared changes in control group´ s and treatment group´ s gait characteristics before and after exercise as percentage, and applied paired t-test to conduct before-after test in same group. Statistical significance level was a < 0.05. The results of this study were as follows.
As a result of independent sample t-test for control group´ s and treatment group´ s gait characteristics after exercise, it was not statistically significant so there was no meaningful difference between two groups. However, it was statistically significant in the change rate(%) of gait characteristics, and treatment group´ s patients with heiniplegia had been highly changed in gait characteristics in comparison with control group.
From the above-mentioned results, could find that pelvic tilt exercise using visual feedback for patients with heiniplegia was effective to improve their gait ability and it could increase the ability in comparison with general pelvic tilt exercise. In the future, studies on the effect of pelvic tilt exercise using visual feedback shall be continued based on more quantitative methods.
