Observational Study of the Analgesic Effect of Treatment With rTMS in Patients With Chronic Neuropathic Pain (rTMSDOULNEURO)
Observational Study of the Analgesic Effect of Treatment With rTMS in Patients Suffering From Chronic Neuropathic Pain Refractory to Conventional Treatment and Monitored and Evaluated in Consultation Multidisciplinary Chronic Pain in Lower Normandy
For ten years, rTMS, repetitive transcranial magnetic stimulation of the motor cortex, has found its place in the treatment of drug-resistant neuropathic pain. Patients relieved by some sessions may thereafter receive a chronic invasive stimulation via electrodes implanted through a neurosurgical procedure. This is common practice at the University Hospital of Caen and in different CHU with the proper equipment rTMS. It seems permissible to provide in our center only a non-invasive technique for patients challenged with brain surgery, since according to the various meta-analyzes the analgesic efficacy of rTMS seems to be correlated to the repetition of sessions.
Assessment centers and the treatment of pain allow a multidimensional assessment, bio-psycho-social of patients in order to optimize their management and experience efficiently analgesics first- and second-line.
We propose a study evaluating the analgesic efficacy of rTMS, in relevant stimulation parameters reproduced according to a literature review, during 3 months after 5 active sessions separated by one week apart, in 15 patients with neuropathic pain chronic refractory to treatment of first and second line, followed by multidisciplinary center specializing in chronic pain Lower Normandy. The quality of life will also be assessed by validated scales, and the results will be compared to the literature data.

analgesic effect of rTMS
Observe the analgesic effect of rTMS, reference method of noninvasive stimulation of the motor cortex validated by data from the literature and current practice, after 5 separate sessions a week apart, patients with neuropathic pain chronic, refractory to first and second-line treatments proposed in a multidisciplinary center specializing in chronic pain Lower Normandy.
