Treatment of pudendal neuralgia by high-frequency rTMS of the medial wall of motor cortex bilaterally using an angled figure-of-eight coil

High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) of the motor cortex was shown effective in treating chronic pain, in particular neuropathic pain [1]. A flat figure-of-8 coil is classically used, focusing cortical stimulation in the superficial layers of the motor cortex [2]. Deeper brain structures can be stimulated by other types of coils (e.g., double-cone or H-coil), but their value to modulate pain perception remains controversial [3]. In fact, these coils stimulate more deeply but also more broadly the brain.
