How Does Neurostimulation Work?

Neurostimulation works by intercepting pain signals before they reach the brain. To do this, a small system is implanted within the body. This system, similar to a cardiac pacemaker, is used to replace pain with a different feeling. Some people describe this feeling as a gentle massaging sensation or, in some cases, simply the absence of pain.

  • Pain signals travel up the spinal cord to the brain.
  • A generator sends pulses to a lead (a thin wire).
  • The lead delivers these pulses to nerves along the spinal cord.
  • The pulses block the pain signals before they reach the brain.
  • The painful feeling is replaced with a more pleasant sensation.
