한국인과 서구인 청년층의 보행특성 비교 = A Comparison of Gait Characteristics between Korean and Western Young People

다국어 초록 (Multilingual Abstract)

It is important to analyze the characteristics of normal gait in clinical and biomechanical aspects. Although gait characteristics can be varied by anthropometric, racial and cultural factors, normal gait studies have been performed mostly for Western people. The present study conducted a gait analysis for Korean young adults and compared the gait characteristics with those of Western people for the establishment of Korean normal gait data. A total of thirty-two adults in twenties(20 males and 12 females) were participated in the gait experiment and their spatio-temporal and kinematic/kinetic gait characteristics were analyzed. The comparison of the gait characteristics between Korean and Western people, revealed that the stride length and walking speed of Korean were significantly smaller than those of Western people by 0.1~0.3m and 0.15~0.40m/s respectively. And the knee abduction moment of Korean was larger than that of Western people, while the other moments(such as hip flexion/extension moments, abduction/adduction moments, and knee flexion/extension moments) were smaller than those of Western people. The ranges of joint angles between the gait studies were largely different with each other, but most of motion patterns and excursions were similar.
