Temporal Interference Stimulation for Upper-Limb Motor Recovery in Early Subacute Stroke

This study aims to test whether transcranial temporal interference stimulation (tTIs) can improve upper limb motor function in patients in the early subacute stage after acute ischemic stroke. Participants will be randomly assigned to receive either active tTIs treatment or sham stimulation. All subjects will receive routine rehabilitation. The treatment will be given once daily for 20 consecutive days. Researchers will assess upper limb motor function before treatment, during the intervention and after the treatment course to compare the effect between the two groups. Safety will also be monitored throughout the study.
