What do you feel if I apply transcranial electric stimulation? Safety, sensations and secondary induced effects

Can Transcranial Direct Current Stimulation Improve Muscle Power in Individuals With Advanced Weight-Training Experience?

“…Thereby, future trials should explore the efficacy of combining tDCS with strength training to improve jumping performance-related outcomes. Furthermore, as tDCS has been associated with side effects such as itching, pain, fatigue, among other (9), future trials should also assess if regular stimulation procedures during training may cause any kind of adverse effect.…”

Assessing cortical synchronization during transcranial direct current stimulation: A graph-theoretical analysis

“…All subjects were informed of the experimental procedures and provided written informed consent before the experiment. The experimental protocol was performed in accordance with the safety procedures for non-invasive brain stimulation (Poreisz et al, 2007;Fertonani et al, 2015), and it was approved by the Ethics Committee of IRCCS Centro San Giovanni di Dio, Fatebenefratelli, Brescia, Italy.…”

“…This procedure ensured that the subjects felt the tingling sensation at the beginning of the stimulation. At the end of the experimental protocol, the participants completed a questionnaire about sensations experienced during each stimulation session to evaluate whether the tDCS caused any discomfort (Fertonani et al, 2015).…”

Bursts of transcranial electrical stimulation increase arousal in a continuous performance test

“…At the end of each experimental session, all participants completed a questionnaire to evaluate possible discomfort and perceived influences on the performance induced by tES (Fertonani et al, 2010(Fertonani et al, , 2015. In the present experiment, it was absolutely necessary that participants did not perceive any difference between real and sham stimulation, because the mere sensory stimulation could mimic the expected arousal effects.…”
