다국어 초록 (Multilingual Abstract)

The purpose of this study is to analyze and compare differences in joint changes associated with the walking speed of typical adults. Additionally, it seeks to collect essential data for the development of customized exercise programs. To accomplish this, the research enlisted 27 adult participants residing in S City, Jeollanam-do, and conducted an analysis of how joint changes differed depending on their walking speed. A one-way analysis of variance(ANOVA) was performed to assess the differences in joint variables based on walking speed. When statistically significant differences emerged among the groups, further investigations were carried out to identify which groups exhibited distinctions, using Bonferroni post-hoc tests. A significance level of α=0.05 was applied to all statistical tests. Ultimately, the following conclusions were drawn.
While there were no changes in cervical posture associated with walking speed, significant posture changes were observed in the trunk as walking speed changed. In terms of hip changes related to walking speed, the extension/flexion angle of the right anterior hip was significantly higher during medium speed, compared to normal and high speeds. Conversely, the rotation angle of the left internal hip exhibited significant increases when walking speed exceeded the normal pace.
The analysis findings regarding pelvic-related variables indicated that, when compared to the normal speed, the right rotation angle was significantly reduced at the medium speed. Furthermore, the angles for left pelvic elevation and depression factors were significantly larger at the normal speed in contrast to the high speed.
Regarding the factors related to the knee joint, it was observed that the right extension and flexion exhibited significantly larger angles at the higher speed compared to the normal speed. Conversely, the flexion and extension factors of the left knee joint showed significantly larger angles at the medium speed compared to the normal speed.
In conclusion, it is essential to further investigate these biomechanical strategies across diverse demographic groups and contribute to the development of customized intervention methodologies. These methodologies, in turn, will provide optimized therapeutic and rehabilitation strategies for individual patients or specific cohorts with gait abnormalities, resulting in improvements in walking functionality and overall functional optimization.
