Multifocal HD-tDCS and Motor Function (NCT06561165)
🩺 Plain-English Summary (8th-Grade Level)
The purpose of this study is to understand how the brain controls movement and how Non-invasive Brain Stimulation (NIBS) with a technique called High-density transcranial direct current stimulation (HD-tDCS) can alter brain processes to improve behavior. Participants in this study will be randomized to either HD-tDCS with standard intervention or personalized dose-controlled multifocal network-targeted HD-tDCS. The hypothesis is that dexterous hand function will improve after a standard HD-tDCS dose and increase even more after personalized dose-controlled multifocal network-targeted HD-tDCS.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (5 items) and avoid the listed exclusions (24 items).
