What the trial is, and whether it could suit you
High-frequency repetitive transcranial magnetic stimulation (rTMS) of the primary motor cortex (M1) has shown its efficacy to alleviate pain in patients suffering from refractory neuropathic pain. rTMS is now considered as 3rd-line therapy (by the French Society for the Study and Treatment of Pain) for patient's refractory to drug therapy.
However, its efficacy in chronic neuropathic pain related to cancer has not yet been specifically studied, and it therefore remains relatively inaccessible for these patients. This project is a cross-over, double-blinded, and placebo-control study, including 5 sessions of either M1 or "sham" rTMS, a wash-out period (8 weeks), followed by 5 sessions of the other stimulation option (I.e., two arms: M1-sham or sham-M1; order randomized between patients). Treatment efficacy will be assessed in comparison to the placebo condition. Primary outcome is the pe
