Effects of Combined Breathing Exercise and Neuromuscular Electrical Stimulation on Patients with Severe COPD

중증 만성폐쇄성폐질환 환자를 위한 복합호흡운동과 신경근전기자극의 효과

This study was designed to examine the effects of complex breathing exercise and neuromuscular electrical stimulation of Quadriceps Femoris muscle on pulmonary function and cerebral cortex activity in patients with severe chronic obstructive pulmonary disease. After collecting samples from 20 patients with severe chronic obstructive pulmonary disease aged 60 to 80, 10 patients each were randomly placed in an experimental group and a control group. The experimental group conducted complex breathing exercise and neuromuscular electrical stimulation of Quadriceps Femoris muscle, and the control group only conducted complex breathing exercise. As a pretest, pulmonary function and cerebral cortex activity were measured. The intervention program was applied to each group for 30 minutes, once a day, for 4 days a week, for 6 weeks, and the posttest was carried out the same way as the pretest. As a result, both groups showed significant differences in FEV1.0(Forced Expiratory Volume in One Second)(p<.001)(p<.05), and there were significant differences between the groups as well(p<.05). When comparing alpha waves in each domain of cerebral cortex, both of the experimental and control groups showed significant differences in Fp1, Fp2, F3 and F4 domains (p<.01)(p<.05). During the 6-week experiment, complex breathing exercise and neuromuscular electrical stimulation of Quadriceps Femoris muscle improved pulmonary function of patients with severe chronic obstructive pulmonary disease, and in relation to cerebral cortex activity, a positive breathing change was found due to the increase of alpha waves in the forehead domain. Therefore, it is considered that applying neuromuscular electrical stimulation of Quadriceps Femoris muscle to patients with severe chronic obstructive pulmonary disease additionally along with complex breathing exercise will bring a better therapeutic effect.

복합호흡운동과 넙다리네갈래근의 신경근전기자극 치료가 중증 만성폐쇄성폐질환 환자들의 폐기능과 대뇌겉질 활성도에 미치는 효과를 알아보고자 하였다. 60~80세 중증 만성폐쇄성폐질환 환자 20명을 대상으로 실험군은 복합호흡운동과 넙다리네갈래근의 신경근전기자극을, 대조군은 복합호흡운동만을 실시하였다. 사전 검사로 폐기능과 대뇌겉질 활성도를 측정하였고, 중재는 6주 간, 주 4일, 1일 1회, 30분씩 각 집단에 시행한 후, 사후검사를 사전검사와 동일하게 재측정하였다. 그 결과 집단 내 폐기능 변화는 실험군과 대조군 모두 1초간 노력성 날숨량에서 유의한 차이가 있었고(p<.001)(p<.05), 집단 간 폐기능 변화 비교에서 1초간 노력성 날숨량의 변화는 유의한 차이가 있었다(p<.05). 집단 내 대뇌겉질의 영역 별 알파파 변화 비교에서는 Fp1, Fp2, F3, F4 영역에서 대조군과 실험군 모두 유의한 차이가 있었다(p<.01)(p<.05). 따라서 6주 동안의 복합호흡운동과 넙다리네갈래근의 신경근전기자극은 중증 만성폐쇄성폐질환들의 폐기능을 향상시키고, 대뇌겉질 활성도에서 앞이마부 영역의 알파파가 증가되어 긍정적인 호흡의 변화가 나타났음을 알 수 있었다. 따라서 중증의 만성폐쇄성폐질환 환자들에게 복합호흡운동 뿐만 아니라 부가적으로 넙다리네갈래근에 신경근전기자극을 병행하면 보다 좋은 치료적 효과를 볼 수 있을 것으로 생각된다.
