Abstract

The purpose of this study was to analyze the changes in gait according to four style of bag's carryied method and three different bag's weights. Twenty healthy adults participated in four conditions. The first condition, they wearing a bag on one side shoulder and walked. The second condition, they carried a bag sling across on shoulder and walked. The third condition, they carried a bag on a back using both shoulders and walked. The fourth condition, they hold a bag in their right hand and walked. During all four conditions participants wore a SmartStep insole in their right shoe and had a pressure control device strapped to their right ankle. Each participant walked 10 meters carrying a 2.5 kg, 5 kg and 7.5 kg bag under all four conditions. There were significantly differents in stance phase rate; swing phase rate and walking speed according to bag weight of 2.5 kg, 5 kg, 7.5 kg.

본 연구는 네 가지의 가방 휴대방법에 따라 세 가지 가방의 무게를 달리하여 보행의 변화를 분석하고자 시행하였다. 20명의 건강한 성인이 연구에 참여하였다. 첫 번째 조건은 한쪽 어깨에 가방을 메고 보행하였고, 두 번째 조건은 한쪽으로 가로질러 가방을 매고 걸었다. 세 번째 조건은 양쪽 어깨에 가방을 메고 걸었고, 네 번째 조건은 한쪽 손으로 가방을 들고 걸었다. 각 네 가지 조건에 모든 대상자가 참가하였고, 오른쪽 신발에 SmartStep의 깔창을 깔고 오른쪽 발목에는 압력제어장치를 묶었다. 모든 대상자는 각각 4가지 조건에서 2.5 kg, 5 kg, 7.5 kg의 무게를 지닌 가방을 휴대하여 10 m를 걸었다. 각 조건에서 2.5 kg, 5 kg, 7.5 kg의 가방의 무게에 따라 입각기 비율, 유각기 비율과 보행속도는 통계학적으로 유의한 차이가 있었다.
