The aim is to study another alternative for the treatment of pain in people with CRPS. Indeed, the TRAB / Medullary occupational therapy department of the CMRRF in Kerpape used compression garments to reduce edema when it was present.In the case of CRPS of the upper limbs, gloves or compression sleeves are used to decrease the edema which is sometimes associated, although they are not supported for this indication. In this context, our clinical experience leads us to believe that there would also be some efficacy in neuropathic pain, this improvement being regularly described by patients.This study is expected to show a notable reduction in neuropathic pain thanks to the wearing of a compression garment.
