초록

본 연구는 발의 피로와 통증을 줄이고 발의 정상적인 기능을 유지해주는 기능적 인솔 적용 유무가 노인 보행 시 하지의 생체 역학적 변인 및 패턴에 미치는 영향을 규명하고자 하였다. 본 연구의 대상자는 10명(연령, 73.2 세: 신장, 152.1 cm: 체중, 59.4 kg)이며, 기능적 인솔 착용과 비 착용 시의 보행을 분석하였다. 보행분석은 퀄리시스 시스템 (Qualisys system)으로 촬영 후 비쥬얼 3D (Visual-3D)로 분석하였다. 그 결과, 기능적 인솔을 착용했을 경우, 보장과 유각기 속도가 유의미하게 증가하였다 (p<.05). 또한 하지의 신전 모멘트가 입각기에서 유의미하게 증가하였다 (p<.05). 본 연구 결과 기능적 인솔은 노인의 보행 안정성을 향상시는 효과가 있었다. 그러나 이 연구의 결과를 일반화하기 위해서는 더 많은 대상자들을 통해 보다 많은 정량적 자료를 축적할 필요가 있으며, 대상자들에게 오랜 시간동안 인솔을 사용하게 한 후 보행변인 및 패턴의 변화를 검토하는 연구가 추후 이뤄져야 할 것으로 판단된다.

This study verified the difference in biomechanical variation and the pattern of the lower limb between using or not using functional insoles on the gait of elderly people. Ten females subjects were selected (age: 73.2 years, height: 152.1 cm, body mass: 59.4 kg) for testing their gait with using functional insoles and without using functional insoles. The gait motions were captured with the Qualisys system and the gait parameters were calculated with Visual-3D. As a result, the subjects' stride length and swing time were significantly increased (p<.05). Also, the lower limb's extension moment was significantly increased (p<.05) when using the insole. These differences suggest the functional insole used in the experiment increases the subjects' gait stability. However, to generalize the results of this study, it is necessary to accumulate more quantitative data with more subjects. Further studies to examine gait variables and changes of walking patterns need to be conducted by gathering and utilizing the results of those subjects who have used insoles for a long period of time.
