About this trial
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.

Treatments tested in this trial
transcranial direct current stimulation
Other interventionprogressive increase in stimulation intensity up to 2 mA, then continuation at a plateau for a total of 20 minutes, then a decrease in stimulation intensity for 30 seconds at the end of the session before an automatic stop.
Placebo
Other interventionThe stimulation intensity is gradually increased up to 2 mA for 1 minute, then decreased to zero stimulation. A further increase in stimulation is programmed 10 minutes after the start of stimulation.
