Analgesic effects of navigated motor cortex <scp>rTMS</scp> in patients with chronic neuropathic pain

Abstract

Navigation may improve HF-rTMS efficacy in patients with limb pain, whereas targeting remains to be optimized for more diffuse or facial pain. WHAT DOES THIS STUDY ADD?: To produce analgesic effects, HF-rTMS should be applied over the precentral cortex contralaterally to the painful side. Although the hMHS is the target normally chosen for stimulation, the optimal target has not been defined yet. Neuronavigational methods have been recently developed; they allow the integration of MRI data and are thought to improve rTMS efficacy.
