Abstract

This study conducted systematic review and meta-analysis to analyze the effectiveness of a dual-task for cognitive function in patients with MCI in Korea. A search was conducted using eight databases, and the search terms were MCI, cognition, and dual task. This study includes RCT and nonRCT published from January 2013 to July 2023. A total of 682 studies were searched, and 8 studies that fulfilled the inclusion and exclusion criteria were finally analyzed. Methodological quality was assessed with the RoB, RoBANS. The meta-analysis used CMA 4.0 ver. As a result of the analysis, the overall effect size of the dual task was medium effect size. The effect size according to the outcome variables was large for orientation and executive function, and medium effect size for global cognitive function, visuospatial function, memory, and attention. As a result of analysis according to the intervention period, the effect was greater when applied for 4 to 8 weeks, and the effect size was larger when applied for 24 to 30 sessions. This study presented clinical evidence on the effectiveness and application method of a dual-task applied to improve cognitive function in patients with MCI.

본 연구는 국내 경도인지장애 환자의 인지기능을 위한 이중과제 프로그램의 효과를 분석하기 위해 체계적 문헌고찰 및 메타분석을 시행하였다. 8개의 데이터베이스를 사용하여 검색하였으며, 검색어는 경도인지장애, 인지, 이중과제였다. 2013년 1월부터 2023년 7월까지 출간된 문헌 중 무작위 및 비무작위 대조군 실험설계를 분석하였다. 총 682편의 문헌이 검색되어 포함 및 배제 기준을 충족한 8편의 문헌을 최종 분석하였다. 문헌의 질 평가는 RoB와 RoBANS를 사용하였다. 메타분석은 CMA 4.0 ver.을 사용하였다. 분석 결과 이중과제 프로그램의 전체 효과 크기는 중간 효과 크기였다. 결과변수에 따른 효과 크기는 지남력, 실행기능은 큰 효과 크기이며, 전반적 인지기능, 시공간기능, 기억기능, 주의기능은 중간 효과 크기였다. 중재 기간에 따른 분석 결과 적용 기간은 4~8주 적용이 효과가 더 크게 나타났으며, 총 회기에서는 24~30회기 적용의 효과 크기가 더 크게 나타났다. 본 연구는 경도인지장애 환자의 인지기능 증진을 위해 적용된 이중과제 프로그램의 효과 및 적용 방법에 대한 임상적 근거를 제시하였다.
