Background: The purpose of this study is to investigate the effect of ultra-thin microcurrent patch application on pain, tenderness, trunk flexion, and trunk extension in patients with back pain. Design: pretest-posttest design: single blind. Methods: Thirty men and women diagnosed with chronic back pain were classified into 15 microcurrent application groups and 15 placebo groups. Changes in pain were observed on a visual analog scale, tenderness was observed with a digital tenderness meter, and changes in trunk flexion and trunk extension angles were evaluated with a posture analyzer. The paired t-test was used to see the changes within each group before and one week after the experiment, and the independent t-test was used to see the change in the difference between the groups, and the significance level was 0.05. Results: In both the experimental group and the control group, there was a significant difference in pain within and between groups(p<0.05). In the experimental group, there were significant differences in the intra- and inter-group changes in the erector spinae muscle tenderness and low back pain disorder index(p<0.05). In the experimental group, there was a significant difference in the change in trunk flexion and extension within the group(p<0.05). Conclusion: In this study, it was confirmed that the application of ultra-thin microcurrent was effective for pain, tenderness, and movement of back extension in patients with low back pain. It is expected that it will be used as a basic data for microcurrent therapy and as a treatment method for improving the function of patients with back pain in the future.

본 연구는 손목 부위에 통증을 호소하는 일개 대학 재학생을 대상으로 환측 경혈(내관, 외관, 합곡, 족삼리)에 미세전류 패치를 부착하여 통증 강도와 악력에 미치는 효과를 확인하기 위한 유사실험 연구로, 비동등성 플라시보 대조군 전후 시차설계이다. 연구는 2023년 10월 31일부터 2023년 11월 27일까지 B시에 위치한 P대학교 재학생을 대상으로 진행되었으며, 실험군 23명과 대조군 23명을 포함한 총 46명이 참여하였다. 수집된 자료는 SPSS 23.0 프로그램을 이용하여 분석하였다. 동질성 검정은 카이제곱 검정과 독립 표본 t-검정을 사용하였고, 실험 후 집단 간 종속변수의 차이는 독립 표본 t-검정으로, 집단 내 종속변수의 차이는 대응 표본 t-검정으로 분석하였다. 2주간 미세전류 패치를 적용한 실험군은 일반 원형 밴드를 적용한 대조군에 비해 통증 강도는 유의하게 감소하였으며(t=7.78, p<.001), 악력은 유의하게 증가하였다(t=-0.75, p=.038). 이에 따라 미세전류 패치는 통증 완화 및 근력 향상에 긍정적인 효과가 있는 것으로 확인되었다.
