“…Stimulation of low threshold mechanical Aβ fibers within specific painful dermatomes at anatomic positions other than spinal cord (the peripheral nervous system) may overcome these problems. Based on our review of the literature, sacral nerve root stimulation seems to be very effective (2,5,7–9,11–17) as an alternative to SCS. Pelvic pain is mediated mainly by sacral afferent parasympathetic fibers of S2–S4 and, therefore, S2, S3, and S4 nerve roots are appropriate targets for electrical stimulation.…”
