Spinal Cord Stimulation (SCS)

Advanced Neuromodulation for Chronic Pain

Spinal cord stimulation (SCS) is an advanced pain treatment that uses electrical impulses to block pain signals before they reach the brain. It’s often used when injections and surgery have not provided adequate relief.

What Is Spinal Cord Stimulation?

In simple terms: A small device implanted near the spine sends electrical pulses that reduce pain signals.
Scientifically: SCS involves percutaneous or paddle-lead implantation in the epidural space, connected to an implanted pulse generator (IPG). It modulates dorsal column activity, altering pain perception via gate control and central mechanisms.

Conditions Treated

Chronic pain syndromes
Post-surgical pain (failed back surgery syndrome)
Radiculopathy not relieved by surgery
Neuropathic limb pain
Complex regional pain syndrome (CRPS)

The SCS Process: Step by Step

1. Trial Phase

Leads temporarily placed in epidural space.
External stimulator used for several days.
If >50% pain relief achieved → proceed to permanent implant.

2. Permanent Implant

Pulse generator implanted under skin (abdomen or buttock).

Leads connected to generator; programming tailored to patient.

Benefits of SCS

Pain relief without further major surgery
Reduces reliance on medications
Reversible and adjustable therapy
Long-term relief for many chronic pain patients

Risks & Limitations

Lead migration or device malfunction (rare)
Infection or bleeding
Not effective for everyone (trial ensures selection)

Recovery Timeline

Trial: Outpatient, minimal recovery needed
Implant: 1–2 weeks for incision healing; full activity in 6 weeks

Long-term: Device programmed and adjusted for optimal results
