Background Stroke is a leading cause of neurological impairments in language, motor and cognitive functions. Next to traditional stroke treatment, Non-Invasive Brain Stimulation (NIBS) offers the potential to facilitate stroke recovery as a complementary approach. Here, we aim at exploiting the principles of NIBS, specifically transcranial Alternating Current Stimulation (tACS), to promote functional recovery of people with neglect symptoms following stroke. Objective To determine whether neglect training complemented with tACS treatment in chronic stroke patients suffering from neglect improves neglect-related symptoms compared to neglect training with sham stimulation. Study design Double-blind randomized placebo-controlled intervention study. After enrollment and completion of baseline measurements, participants are randomly assigned to either the active tACS group or sham (control) group. Intervention We will combine an evidence based visual scanning training (VST) with 40 minutes of (active or sham) tACS at alpha frequency. The intervention is administered three times a week for a duration of six weeks. Outcomes of the study Performance on standard, conventional neuropsychological tests, as well as on ADL observation scales.

Timeframe: Testing will take place before the training (T0; baseline), after the first (T1), ninth (T2), and eighteenth (T3) training session, as well as one week (T4) and three months (T5) after termination of the training.
