Summary

The goal of this clinical trial is to verify the effect on the voice of transcranial direct current stimulation (tDCS) in vocally healthy non-singers. The main question it aims to answer is: What is the brain area in which tDCS promotes better vocal performance in vocally healthy individuals? Each participants received anodal tDCS applied at an intensity of 2 mA for a duration of 20 minutes for tDCS stimulations in different areas with a 7-day washout period between stimulations. Vocal assessments was conducted before and after the intervention. The targeted places were the primary motor cortex (M1), primary somatosensory cortex (S1), Cerebellum, and dorsolateral prefrontal cortex (DLPFC).

Conditions

  • Voice and Resonance Disorders
  • Transcranial Direct Current Stimulation
  • Voice Disturbance

Interventions

DEVICE

Transcranial direct current stimulation

Anodal tDCS will be applied at an intensity of 2mA and duration of 20 minutes. The assembly of the electrodes during the tDCS sessions will be carried out as follows: primary motor cortex, the stimulation electrode (anode) will be positioned on C5 (international EEG 10-20 system), in S1 (2cm posterior to C5), at the PFCDL (Fp3), all with the cathode positioned on the region contralateral supraorbital. For cerebellar tDCS the anode will be positioned on the inion area and the cathode on the deltoide muscle.
