Clinical Trial Summary

To investigate the effects of different montages of tDCS on muscle strength in healthy adults

Description:

Electrode montage or placement of tDCS over primary motor cortex can be categorized into unilateral (anodal or cathodal electrode over primary motor area) and bilateral tDCS (both anodal and cathodal electrode over the cortex). Previous studies reported benefits of different tDCS montages on muscle performance in healthy participants. However, there is no guideline for tDCS montages. This study aims to investigate immediate effects of different tDCS montages on muscle strength in healthy participants.
