Spinal Cord and Peripheral Nerve Stimulation

Spinal Cord Stimulation (SCS)

Spinal cord stimulators are implantable devices that deliver low-level electrical pulses to the spinal cord. These pulses help "mask" pain signals and replace them with a tingling sensation (or no sensation at all). SCS is commonly used for:

• Failed back surgery syndrome (FBSS)
• Chronic back or leg pain
• Complex regional pain syndrome (CRPS)
• Neuropathic pain that hasn’t responded to other treatments

Most patients try a trial device first to see if SCS works for them before getting a permanent implant.

Peripheral Nerve Stimulation (PNS)

PNS works similarly to spinal cord stimulation but targets nerves outside the spinal cord. A small electrode is placed near the painful nerve to interrupt abnormal pain signals. It can be helpful for:

• Nerve injuries
• Post-surgical pain
• Headaches or facial pain
• Localized nerve pain in the arms, legs, or torso

PNS is minimally invasive and often reversible, with both temporary and long-term options available.

Dorsal Root Ganglion (DRG) Stimulation

DRG stimulation is a more targeted form of spinal cord stimulation that focuses on the dorsal root ganglia—nerve bundles along the spine that transmit pain from specific body regions. It’s especially effective for:

• Complex Regional Pain Syndrome (CRPS)
• Focal neuropathic pain (especially in the foot, groin, or knee)
• Pain after surgery or trauma in a specific area

DRG therapy is known for its precision, providing focused pain relief without widespread numbness or tingling.
