Brief 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
Detailed Description:
Recently non-invasive brain stimulation NIBS techniques including transcranial direct current stimulation tDCS have been employed to enhance vocal skills tDCS can be used to temporarily and reversibly modulate brain functions and is an increasingly popular tool for investigating the relationships between the brain and behavior The aim of the present study is investigate the effect of tDCS applied to different areas on the voice of vocally healthy non-singers This is a randomized crossover clinical trial approved by the Research Ethics Committee of the Federal University of Pernambuco number 5758856 Vocally healthy people from the city of Recife and its Metropolitan Region aged between 18 and 45 years participated in the studyEach participant underwent four tDCS stimulations in different areas with a 7-day washout period between stimulations to study their vocal assessments before and after tDCS The targeted places were the primary motor cortex M1 primary somatosensory cortex S1 Cerebellum and dorsolateral prefrontal cortex DLPFC All participants were subjected to voice acessments analysis immediately before and after tDCS application in each area Data normality will be analyzed using the Shapiro-Wilk test rejecting the hypothesis of normal distribution when p005 ANOVA will be applied to design repeated measures in case of normality and in the existence of asymmetric data Friedmanns ANOVA will be used for repeated measures For the comparison of values before and after application of the technique and between modes of execution of the technique with and without non-invasive neuromodulation tests will be applied for related and independent samples respectively with a significance level of 5
