3차원 관절 전기측각기를 이용한 정상성인의 보행분석결과

Abstract

Background: The aim of this study is to present the basic reference data of kinematic gait analysis of normal Korean adults with 3 dimensional electrogoniometer, DomotionⓇ. Method: The basic kinematic gait parameters of hip, knee and ankle joints on the sagittal plane were obtained from 10 healthy adults with 5 repetition for each. Three-dimensional gait analysis was performed with DomotionⓇ electrogoniometer in 10 meters long flat floor. Each data collected was processed with IBM PC equipped with gait analysis program. R e s u l t s: Mean maximal hip flexion was 23.05°±4 . 6 2°and mean maximal hip extension was 6.46°±1 . 3 0°. Knee flexion was observed with two peak values. The first peak knee flexion was 6.50°±2.07°at 20.4% of gait cycle and the second peak flexion was 50.34°±2.23°at 75.8% of gait cycle. Mean maximum ankle dorsiflexion was 5.57°±1.19°at 44% of gait cycle and mean maximum ankle plantar flexion was 15.51°±1.73°at 68.5% of gait cycle. Conclusion: We concluded three dimensional gait analysis with electrogoniometer DomotionⓇ offers a valid and reliable kinematic data and the application of this tools for clinical gait evaluation will be helpful in management of pathological gait.
