Modulation de l'excitabilité Des Aires Corticales Motrices Primaires Correspondant Aux hémi Diaphragmes à l'Aide de la tDCS (Transcranial Direct Current Stimulation)
In Brief
A clinical study evaluating Eldith DC stimulator ( Magstim Company Ltd. UK) for Excitability of Diaphragmatic Primary Motor Cortex. Completed, enrolled 12 participants across 1 site.
Detailed Summary
Transcranial direct current stimulation (tDCS) is a non invasive, painless, harmless way to modulate cerebral cortex excitability. It was shown that anodal stimulation increases cortical excitability and the cathodal one decreases it (Nitsche and Paulus, 2000; Lang et al. 2004). To date, there is no data in the literature regarding the effect of tDCS on the corticodiaphragmatic pathways. This preliminary study aims to test and validate the modulating effect of tDCS on the excitability of the primary motor cortex dedicated to the hemi-diaphragms in a sample of healthy subjects, as a prelude to further large studies in patients with paretic hemi-diaphragms. Diaphragmatic motor evoked potentials will be assessed before and after applications of three different modalities of tDCS (anodal, cathodal and placebo).
