Effect of Lower Limb Muscle Activity on Balancing through Sprinter Patterns of PNF

Abstract

본 연구는 PNF 중 스프린터 패턴 적용 시 하지의 근 활성도가 균형 능력에 미치는 영향을 알아보고자 다음과 같이 실시하였다. 편마비 환자 24명을 대조군과 실험군으로 나누어 실험군에 주 3회, 6주 동안 PNF의 상 하지 패턴의 결합인 스프린터 패턴(Sprinter pattern)을 실시하였다. 하지 근활성도는 내 외측광근, 내 외측슬괵근, 외측비복근의 활동전위의 실효치 값을 분석하였다. 균형 능력 검사는 FICSIT-4, FSST, MTD-Balance system 이용하여 측정하였다. 운동 적용 방법에 따른 측정 시점에 대한 대조군과 실험군의 유의성 검정은 Two-way repeated measure ANOVA를 실시하였고, 각 측정 항목들 간의 상관관계를 알아보기 위하여 Pearson correlation으로 분석하였다. 그 결과, 스프린터 패턴의 적용은 마비측 하지의 근 활성도를 증가시켜 정적 및 동적 균형능력을 향상시키는데 효과가 있었음을 확인할 수 있었다. 따라서 마비측 하지의 효율적 근동원을 위한 치료적 중재프로그램으로 적극적인 활용과 함께 다양한 운동 패턴들과 결합시켜 새로운 중재를 개발할 필요가 있을 것으로 생각된다. In this study, for examining an effect of lower limbs' muscle activity on balance capability when applying sprinter pattern among the PNF, the experiment was conducted as followed. Under the object of 24 people diagnosed by hemiplegia, they were divided into control group and experimental group and the experiment was conducted on the experimental group, three times per a week for six weeks. Experimental group received Sprinter pattern of combined PNF upper extremity and lower extremity pattern. For the lower limbs' muscle activity, effective values of Vastus medialis laterails, medial lateral hamstrings, lateral gastrocnemius' action potential were analyzed. The balance ability tests was conducted with FICSIT-4, FSST and MTD-Balance system. For the significance test of control group and experimental group for measuring time by exercise application method, two-way repeated measure ANOVA was conducted and for the significance test among the groups by each measuring time, independent t-test was conducted. Also, for examining the correlation among the measuring item, pearson correlation was used for the analysis. As the result, the application of sprinter pattern increased muscle activity of lower limbs in paretic side and improve static and dynamic balance ability effectively. Therefore, it will be necessary to develop new intervention by combining active application of the therapeutic intervention program for lower limbs' effective muscle mobilizing in paretic side with various exercising patterns.
