Objective: The aim of the study is to re-evaluate the methodological quality and quality of evidence for a systematic evaluation/meta-analysis of the effect of mirror visual feedback therapy on physical function re-education after stroke.
Methods: Systematic evaluations/meta-analyses of mirror visual feedback therapy on physical function re-education after stroke were searched in the China Knowledge Network database, Wanfang database, Vipers database, China Biomedical Literature database, PubMed, Web of Science, and Embase using a computer, and the search time frame was up to January 2022. Methodological quality and quality of evidence ratings of the included studies were determined using the AMSTAR2 scale and GRADE classification by two authors.
Results: Seventeen publications were included. The evaluation with the AMSTAR2 scale showed that one study had an intermediate quality rating, five had a low-quality rating, and the remaining 11 were all very low quality. The GRADE scale showed 93 outcome indicators, of which 6 were intermediate, 23 were low grades, and the rest were very low grades, with low overall quality.
Conclusions: Mirror visual feedback therapy is efficacious for physical function re-education after stroke and promotes recovery from physical dysfunction, but the methodological quality and quality of evidence from the related systematic evaluations/meta-analyses are low.
