Efficacy of Ericksonian Hypnosis in the Management of Chronic Pain Related to Parkinson's Disease

This study evaluates the efficacity of Erickson hypnosis in the treatment of chronic pain in patients with Parkinson's disease. Half of participants will follow a 2-month Erickson hypnosis protocole, while the other half will benefit from the usual care.

A large proportion of patients with Parkinson's disease suffer of chronic pain directly related to the disease. The management of painful symptoms is difficult and currently, there is no commonly admitted guidelines. Several studies have shown the efficacy of Erickson hypnosis to reduce the perception of chronic pain in different conditions. This efficacy has never been tested in Parkinson's disease. The objective of this study is to assess the efficacy of Erickson hypnosis protocol, compared to usual care, for the management of Parkinson's disease-related chronic pain. The study team assume that Erickson hypnosis will be more efficient than usual care to reduce perceived chronic pain. They also assume that regular practice of autohypnosis will contribute to long-term efficacy.
