P 172. Focal tDCS in Chronic Stroke patients: A pilot study of physiological effects using TMS and concurrent EEG

We report results of MEPs, EEG, and motor behavior. We show, for the first time, that tDCS and EEG recording can be concurrently applied in stroke patients. Bilateral M1 stimulation using small Ag/AgCl electrodes is well tolerated and can augment corticospinal excitability in the affected hemisphere. In the literature, there is only one prior studying using concurrent EEG recording during cathodal tDCS in healthy subjects and two patients with epileptic encephalopathy (Faria et al., 2012). As far as we know, no studies have applied tDCS simultaneous with EEG recording in chronic stroke patients. We report the first study investigating feasibility and proof-of-concept of tDCS in 15 chronic stroke patients using EEG recording simultaneously with tDCS. With continuous EEG recording and neurophysiological data, we hope to gain insight into the mechanisms of biological responses to tDCS and the behavioral changes resulting from stimulation.
