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

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.
