미세전류 자극이 보행 개선에 미치는 효과

The effects of microcurrent stimulation for gait improvement

본 연구는 ATP 생성에 효과적인 500㎂의 미세전류를 지연성 근육통이 유발된 다리근육에 적용하여 보행개선에 효과가 있는지 알아보기 위해 실시하였다. 40명의 대상자를 실험군 20명, 위약군 20명으로 무작위 할당하였다. 지연성 근육통 유발 직후, 24시간 후, 48시간 후에 미세전류를 적용하여 체중심, 분속수 및 환측 입각기의 변화를 측정하였다. 그 결과 지연성 근육통 유발 전에 비해 48시간 후의 체중심, 분속수 및 환측 입각기의 변화가 통계적으로 유의한 차이를 보였으며, 48시간 후 실험군은 위약군에 비해 체중심의 변화가 통계적으로 낮아졌고, 환측 입각기의 비율은 높아졌다. 따라서 500㎂의 미세전류는 손상된 근육의 복원과 치유를 촉진시켜 보행개선에 효과를 보였다

This study was conducted to apply microcurrents of 500㎂ effective for ATP generation to leg muscles to which delayed onset muscle soreness (DOMS) had been induced in order to examine whether the microcurrent stimulation was effective for gait improvement. Forty subjects were randomly assigned to an experimental group of 20 subjects and a placebo group of 20 subjects. Microcurrents were applied immediately after inducing DOMS and 24 hours and 48 hours thereafter and changes in the center of pressure (COP), cadence, and affected stance phases were measured. According to the results of the measurement, changes in the COP, cadence, and affected stance phases at 48 hours after the induction of DOMS were statistically significant compared to the values before the induction. The COP of the experimental group became statistically significantly lower and the ratio of affected stance phases of the experimental group became statistically significantly higher compared to the placebo group at 48 hours after the induction of DOMS. Therefore, 500㎂ microcurrents showed effects for gait improvement by promoting the recovery and healing of damaged muscles.
