Summary

rTMS of the motor cortex is an increasingly established analgesic technique for the treatment of neuropathic pain. However its efficacy is generally modest. One reason may be the that conventional rTMS targets only superficial and small cortical regions of the human brain. A newer cooled coil, the Hesed (H) coils, now allows deep and larger surface of stimulation and has been suggested to have analgesic effects in a small pilot trial in diabetic painful polyneuropathy. Based on its deeper mechanism of action and larger surface of stimulation, we hypothesize that this technique will be more effective than rTMS in patients with central pain, a highly unmet medical need. The primary objective of the present study will be to compare the efficacy of H coil, conventional rTMS and sham stimulation of the primary motor cortex in patients central neuropathic pain. Major secondary objectives will be to directly compare the analgesic efficacy of H coil versus conventional rTMS, and compare the efficacy of both techniques in patients with lower limb pain and those with upper limb pain/face. This will be a randomized tricentric sham controlled study

Conditions

  • Central Pain Syndrome

Interventions

DEVICE

rTMS

Conventional magnetic stimulations will be applied with a MacPROX100 machine using neuronavigation system. H-coil rTMS will be delivered with the Brainsway H-coil (Brainsway, Jerusalem, Israel) applied via a helmet placed on the head corresponding to the primary motor cortex (H10 coil) and connected to a Masgtim Rapid2 stimulatior (Mastim, Whitland, UK), while sham stimulation will be delivered with a sham coil placed in the helmet encasing the active rTMS coil. Active rTMS sessions with H-coil will use exactly the same parameters of stimulation as conventional rTMS.
