초록

이 연구의 목적은 인체모형을 이용하여 옮기기 활동을 하는 동안 발의 배치(11자 배치와 $90^{\circ}$배치)와 옮기는 지면의 높이(휠체어 좌석과 같은 높이와 다른 높이)가 허리척추에 미치는 영향을 알아보는 것이었다. 자발적으로 실험참여에 동의한 건강한 남성 15명을 대상으로 4가지 조건에 따라 옮기기 활동을 실시 하였다. 옮기기 활동 동안 허리척추의 작업부담을 알아보기 위해, 위팔두갈래근, 척추세움근, 넙다리근의 근활성도를 표면근전도로 측정하였고, 힘판을 이용하여 수직 지면반발력을 측정하였고, L4/L5에 가해지는 압박력을 3DSSPP를 이용하여 측정하고 분석하였다. 그 결과, 오른쪽 넙다리근의 근활성도를 제외한 나머지 근육의 근활성도는 각 조건 사이 유의한 차이가 없었다. 수직 지면반발력은 각 조건 사이 유의한 차이가 있었다(p<.05). 또한 L4/L5에 가해지는 압박력은 같은 높이인 경우 발의 배치에 따라 유의한 차이가 있었다(p<.05). 따라서 옮기기 시 발을 11자로 배치하는 것보다 발을 90°로 배치하는 것이 체중이 한쪽으로 쏠리는 경향과 L4/L5 압박력을 줄이는데 도움이 되기 때문에 환자 옮기기 시 이를 적용하는 교육이 필요할 것이다.

The purpose of this study was to investigate the effect of foot placement and height of bed surface on lumbar spine load in a dummy transfer activity. Fifteen healthy male students participated in this study. All subjects were involved in four different conditions according to foot placement (11 figure and $90^{\circ}$ figure) and height of bed surface (44 cm and 66 cm) randomly. Muscular activations of the biceps brachii, rectus femoris, elector spinae using surface-EMG, vertical ground reaction using force plate, and L4/L5 compression force using 3DSSPP (3D Static Strength Prediction Program) were measured and analysed. The results showed that muscular activations were not significantly different for the various conditions except for the rectus femoris on the right side (p<.05). Futhermore, the vertical ground reaction and L4/L5 compression force were significantly different conditions (p<.05). In conclusion, it is suggested that foot placement at $90^{\circ}$ figure is safer for transfer activity compared with the 11 figure.
