Abstract

This study was to performed to get the reference data of the kinetic parameters for normal subjects according to the arm swing type. Forty-five normal subjects($22.62{\pm}2.69years$) pariticpated in this study and preformed 4 sequence according to the arm swing type as follows; first procedure-normal arm swing, second procedure-one arm swing, thrid procedure-no arm swing, fourth procedure-fitness arm swing. There were significant differences according to the arm swing type in the kinetic parameters such as walking speed, hip power, ground reaction force of vertical in terminal stance phase(p<.05). These finding can be utilized (a) as a reference for kinetic data of gait analysis in normal subjects, and (b) as an aide in evaluating and treating patients who have problems relating to gait.

본 연구는 정상 성인의 팔 흔들기 종류에 따른 보행 시 운동역학적인 변화를 알아보기 위해서 실시하였다. 정상 성인 대학생 45명을 대상으로 정상 팔 흔들기, 한 팔 흔들기, 두 팔 움직임 없음 보행, 인위적인 팔 흔들기의 4가지 팔 흔들기 종류에 따라 실험을 진행하였다. 이들의 운동역학적인 변화를 알아보기 위해 3차원적 관절 운동역학적 변화 검사인 6-camera Vicon MX motion analysis system을 통해 보행 변수를 측정하였다. 팔 흔들기에 따른 운동역학적인 매개 변수들인 각 관절에서 보행속도, 엉덩관절 일률, 말기 디딤기의 수직 지면반발력에서 유의한 차이를 보였다(p<.05). 이러한 연구결과는 팔 흔들기 종류에 따라서 정상인과 환자들의 치료와 평가를 위한 지침으로서 임상에서 사용할 수 있을 것으로 생각된다.
