Neuropathic pain - Fibromyalgia - deep rTMS
Brief summary
This study will investigate the efficacy and safety of "deep" rTMS on neuropathic pain or fibromyalgia. It will be randomized and sham controlled and will last 3 months. Patients will be randomized to receive acctive rTMS or sham rTMS and will receive repeated rTMS sessions (5 daily sessions then one session per week then every 2 to 3 weeks for up to 10 weeks).
Detailed description
This double blind sham controlled parallel group bicenter study will assess the efficacy and safety of repeated sessions of deep rTMS using H coil in patients with neuropathic pain or fibromyalgia. Primary outcome will be % of pain relief at week 13.
