Transcranial Direct Current Stimulation Associated With Peripheral Electrical Stimulation for Pain Control in Individuals With Sickle Cell Disease

About the study

So far, no study investigated the safety and efficacy analgesic of transcranial direct
current stimulation (tDCS) associated to peripheral electrical stimulation (PES) in
individuals with SCD who suffer from chronic pain. Several studies have reported a decrease
in O²Hb concentration in the regions below the electrodes and in other cortical areas during
anodic or cathodic tDCS, which implies a risk factor for vasoocclusive events in individuals
with SDC due to polymerization of hemoglobin when exposed to these low O²Hb concentrations.
For this reasion, the aim main of this study is to assess the effect of a single session of
transcranial direct current stimulation (tDCS) associated to peripheral electrical
stimulation (PES) on safety and efficacy analgesic in individuals with sickle cell disease
(SCD). Others aims sencondaries are evaluate the effect of a single session of transcranial
direct current stimulation (tDCS) associated to peripheral electrical stimulation (PES) on
biomarkers neurophysiological and inflammatory.
