Effectiveness of Transcranial Direct Current Stimulation (tDCS) in the Management of Complex Regional Pain Syndrome

Overview

Transcranial direct current stimulation (tDCS) is a non-invasive therapy increasingly used in facilities treating patients with chronic pain. This complementary therapy has the advantage of being non-pharmacological, with transient and mild side effects, an excellent safety profile, and good efficacy in the contexts where it has been the subject of dedicated research: neuropathic pain, fibromyalgia, and visceral pain. Few studies have focused on the application of tDCS in the context of complex regional pain syndrome (CRPS), which is a common condition.

This protocol aims to compare a group receiving a tDCS protocol with a sham control group. The hypothesis of this study is that tDCS is effective in treating CRPS in terms of reducing pain and the functional and emotional consequences of pain. The primary objective of the study is to evaluate the effectiveness of tDCS on pain in patients with CRPS (complex regional pain syndrome), measured by the numerical pain scale (EN), after one month of treatment and one month after the end of treatment, compared to the sham arm. The secondary objectives are: * To assess anxiety and depression symptoms (HAD) * To assess the functional impact of pain (Concise Pain Questionnaire - QCD) * To assess central sensitization (Central Sensitization Inventory - CSI) * To identify adverse effects related to tDCS
