Bifocal Transcranial Alternating Current Stimulation Targeting the Frontoparietal Network in Stroke Patients
Bifocal Transcranial Alternating Current Stimulation Targeting the Frontoparietal Network in Stroke Patients to Enhance Network Connectivity
Source: ClinicalTrials.gov · Last updated 15 May 2026
Brief summary (registry, in English)
Hand and arm function is often significantly impaired in stroke patients, making its recovery a primary goal in rehabilitative treatment. This study investigates the effects of bifocal transcranial alternating current stimulation (tACS) on the frontoparietal network in stroke patients during the subacute to chronic recovery phase. By using non-invasive brain stimulation, the study aims to modulate the neural network connectivity between the ipsilesional parietal and premotor cortices. Electroencephalography and kinematic data will be utilized to assess the impact of tACS on functional connectivity and its subsequent effect on motor function. The ultimate goal is to enhance functional coupling within these networks to promote motor function in stroke patients.
