Dorsal root ganglion stimulation and laser-evoked potentials recovery in patients with neuropathic pain


  • The laser-evoked potential (LEP) gradually recovers within 7 days after dorsal root ganglion stimulation (DRGS) in patients with neuropathic pain, which may mediate neuroplasticity in the nociceptive system.

Why this matters

  • Chronic neuropathic pain is a severe condition involving the dorsal root ganglion that can develop into a long-lasting disease and decrease a patient’s quality of life.

  • DRGS therapy has shown to be a promising and effective method of relieving neuropathic pain, particularly in patients with groin and knee pain.

  • Patients have reported pain relief immediately after DRGS; however, objective neurophysiological evidence is lacking.
