Summary

This study tested two types of non-invasive brain stimulation (called paired associative stimulation) to see if they could help improve hand movement in people who had a stroke. 81 participants (60 stroke survivors and 24 healthy volunteers) took part. The main goal was to understand how the stimulation changes brain activity, not to prove it works as a treatment.
