Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in pain intensity

    Pain assessment at before and after each intervention: Actual pain intensity will be assessed using a 0-10 visual analogue scale (VAS), where 0 is no pain and 10 the worst imaginable pain. Visual analogue scale allows to evaluate the intensity pain of a quantitative way, the subjects will fill a VAS before and after treatment.

    One day

Secondary Outcomes (5)

  • Analysis of brain waves delta, theta, alpha and beta

    One day

  • Dosages of TNF-alpha and BDNF in patients with SCD

    One day

  • Motor cortical reorganization

    One day

  • Impact of pain in functionality

    One day

  • Hospital anxiety and depression scale (HADS)

Interventions

transcranial direct current stimulation (tDCS) uses a pair of electrodes and sponges soaked in saline solution placed over specific regions of the head to polarize neurons and produce changes in resting membrane potentials. This changes may increase or decrease neuronal excitability and produce diverse clinical effects, including analgesia. PES uses also a pair of electrodes over specific regions of the body to promote neuronal action potentials in peripheral nerves. PES over motor threshold increases cortical excitability, and at the sensory threshold decreases excitability.
