Intervention Effect of Transcranial Alternating Current Stimulation (tACS) on Disorder of Consciousness (DOC)

tACS is described as a non-invasive form of brain stimulation that uses a low-intensity, alternating current applied directly to the head through scalp electrodes.

Sham tACS was delivered using the same protocol and current intensity, but the period of active stimulation was only during the ramp-up and ramp-down periods of 30 and 30 seconds.
