Effect of Russian Current Stimulation on Muscular Performance and Muscle Activity of Quadriceps Femoris Muscle of Convalescent Patient after Leg Fracture

국문 초록 (Abstract)

본 연구에서는 하지 골절 후 회복기 환자에게 러시안전류 자극이 넙다리네갈래근의 근수행력과 활성도에 미치는 영향을 알아보기 위하여 실시하였다. 본 연구는 2013년 1월 9일에서 2013년 3월 16일까지 실시하였으며, 하지 골절 후 회복기에 있는 환자 20명을 대상으로 실험을 실시하였다. 러시아 전류자극기의 큰 도자를 넙다리네갈래근의 근위부에 위치하고, 작은 도자는 원위부에 부착시키고 한 주에 세 번, 6주 동안 적용하였다. 대상자의 넙다리네갈래근의 근활성도를 측정하기 위해 근전도가 이용되었고, 근수행력을 측정하기 위해 등속성기기가 이용되었다. 연구결과 기간별 넙다리네갈래근의 근수행력 차이는 러시안전류 치료 전과 비교하여 4주 후와 6주 후에서 유의한 근수행력의 증가를 나타내었다. 또한 넙다리곧은근, 안쪽넓은근, 가쪽넓은근의 근활성도는 치료 전과 비교하여 4주 후와 6주에서 유의한 증가를 나타내었다. 이와 같은 결과는 러시안 전류가 하지 골절 등과 같은 문제로 인해 약화된 하지 근육의 근력 강화를 위해 선택될 수 있는 효과적 치료 방법이라 할 수 있다.

The present study was aimed to comprehend the effect of the Russian current stimulation on the muscular performance and activity of quadriceps femoris muscle of the convalescent patient after the leg fracture.This study conducted test based on 20 patients after leg fracture. Russian current was applied for six weeks as three times in a week, between January 9, 2013 and 15 March 16, 2013. The electromyogram was used to measure the muscle activity of the quadriceps femoris, and the isokinetic equipment was used to measure the muscular performance. The muscular performance difference by duration depending on the application of the Russian current showed the significant increase in all muscular performances. The activity of all muscles of the quadriceps femoris muscle by duration showed significant increase. These results showed that the Russian current can be the effective treatment method for enhancing the muscular strength of the weakened lower limbs muscle due to the problem such as the leg fracture.
