Abstract

This study analyzed the effects of auricular acupressure on improving sleep disorders of the elderly. The data was collected from domestic and foreign databases. The keywords were 'auricular,' 'sleep,' 'insomnia, and so on. RoB and RoBANS were used to evaluate the risk of bias in the selected literature. Meta-analysis was performed using RevMan 5.3. Seven of 386 studies were selected. Regarding the sleep score, those studies with an intervention period of less than four weeks showed WMD of 25.66 (95% CI; 20.18 to 31.14), which was significantly higher than that of the control group. Similarly, the studies with an intervention period longer than four weeks had significantly higher WMD than that of the control group, and the former exhibited WMD of 8.59 (95% CI: 6.26 to 10.92). In contrast, sleep satisfaction was significantly higher in the studies with a maintenance period of three days or less, which resulted in SMD of 13.37 (95% CI: 5.29 to 21.45). The score in the studies with a maintenance period longer than four days was significantly higher than that of the control group with SMD of 2.27 (95% CI: 1.82 to 2.72). Auricular acupressure was effective in alleviating sleep disorders among the elderly in terms of both sleep quality and sleep satisfaction.

본 연구의 목적은 이압요법이 60세 이상 노인의 수면장애 개선에 미치는 효과를 분석하기 위함이다. 자료수집은 국내외 컴퓨터 데이터베이스를 기반으로 하였다. 검색어는 'auricular', 'sleep', 'insomnia' 등을 조합하였다. 선정한 문헌의 비뚤림 위험평가는 RoB와 RoBANS도구를 사용하였고, 메타분석은 Cochrane Library의 RevMan 5.3 Program을 이용하였다. 총 386개의 문헌 중 7개 문헌이 선정되었다. 이압요법 중재 평균 횟수는 4.1회, 총 적용 기간은 평균 2.8주, 이압요법 1회 적용 시 유지 기간은 평균 4일이었다. 수면 장애 개선을 위해 자주 사용한 부위는 신문, 뒷머리, 심장으로 4편의 문헌에서 모두 사용되었다. 수면 정도는 총 중재 기간이 4주 미만인 문헌에서 WMD 25.66 (95% CI 20.18 to 31.14)로 대조군보다 유의하게 높았으며, 4주 이상인 문헌에서는 WMD 8.59 (95% CI 6.26 to 10.92)로 대조군보다 유의하게 높았다. 수면 만족도는 이압요법 1회 적용 시, 유지 기간이 3일 이하인 문헌에서 SMD 13.37 (95% CI 5.29 to 21.45)로 대조군보다 유의하게 높았으며, 4일 이상인 문헌에서 SMD 2.27 (95% CI 1.82 to 2.72) 대조군보다 유의하게 높았다. 이압요법은 수면 정도와 수면 만족도에 효과가 있어 노인의 수면 장애 개선에 효과가 있었다. 그럼에도 불구하고, 본 연구의 메타분석에 이용된 문헌은 모두 비 무작위 대조군 연구이며, 대조군에 아무런 조치도 취하지 않았으며, 주관적 도구만 사용하였다. 또한, 총 중재 기간, 1회 적용 시, 유지 기간에 따라 효과 크기가 다른 것으로 나타났으나, 문헌의 수가 적어 해석에 제한점이 있다.
