摘要

Purpose

To examine the effects of single-dose anodal tDCS on isometric maximal voluntary contraction (MVC) and isometric endurance performance in lower limb exercises with healthy adults.

Methods

For this systematic review and meta-analysis, we searched PubMed, ISI Web of Science, Scopus, and CINAHL for studies published between database inception and June 11, 2024. All randomized controlled trials on anodal tDCS interventions for MVC and isometric endurance in lower limb exercises were included, with no date restrictions. The quality of the evidence was assessed using the Jadad Scale, and the certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. The Open Science Framework registered the protocol in June 2024 (DOI https://doi.org/10.17605/OSF.IO/AG93M).

Results

20 interventions were included, comprising 15 for MVC and 5 for ‘Time to Task Failure’ (TTF), which refers to isometric endurance performance measured in seconds. The findings showed no difference in the MVC (SMD = 0.06; 95% CI = − 0.14, 0.25; P = 0.57) and TTF performance (WMD = 0.07; 95% CI = − 0.26, 0.40; P = 0.68).

Conclusion

The current meta-analysis indicated that anodal tDCS did not increase isometric MVC and isometric endurance performance in lower limb exercises in healthy adults.
