뇌졸중 환자의 동작관찰훈련이 보행에 미치는 효과에 대한 메타분석; 국내연구를 중심으로 = Meta-Analysis on the Effects of Action Observation Training on Stroke Patients’ Walking; Focused on Domestic Research

다국어 초록 (Multilingual Abstract)

Purpose : The purpose of this study was to investigate the meta-analysis on the effects of action observation training on stroke patients‘ walking.
Methods : Domestic databases (DBpia, KISS, NDSL, and RISS) were searched for studies that conducted randomized controlled trials (RCTs) associated with action observation training in adults after stroke. The search outcomes were items associated with the walking function. The 18 studies that were included in the study were analyzed using R meta-analysis. A random-effect model was used for the analysis of the effect size because of the significant heterogeneity among the studies. Sub-group and meta-regression analysis were also used. Egger’s regression test was conducted to analyze the publishing bias. Cumulative meta-analysis and sensitivity analysis were also done to analyze a data error.
Results : The mean effect size was 2.77. The sub-group analysis showed a statistical difference in the number of training sessions per week. No statistically significant difference was found in the meta-regression analysis. Publishing bias was found in the data, but the results of the trim-and-fill method showed that such bias did not affect the obtained data. Also, the cumulative meta-analysis and sensitivity analysis showed no data errors.
Conclusion : The meta-analysis of the studies that conducted randomized clinical trials revealed that action observation training effectively improved walking of the chronic stroke patients.
