The main neuromodulatory methods using neurostimulation principles are described. It concerns peripheral nerve stimulation (PNS), spinal cord stimulation (SCS), deep brain stimulation (DBS), motor cortex stimulation (MSC), and repetitive transcranial magnetic stimulation (rTMS). ⋯ In addition to the positive effects, side effects and complications are described and discussed in detail. In conclusion, neuromodulatory (neurostimulatory) techniques are highly recommended for the treatment of different types of pharmacoresistant pain.
