Peripheral neuropathic pain is a disabling chronic pain condition that is difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) to the motor cortex is a treatment method with growing evidence in its ability to alleviate neuropathic pain. This also applies to new deep rTMS coils which permits stimulation of larger cortical areas and with deeper penetration. The aim of this study is to investigate the analgesic efficacy of 5 days of deep rTMS compared to sham stimulation. We will also assess effects of deep rTMS on sleep, psychological fatctors, everyday functioning, and executive functioning.
