Epidural Spinal Cord Stimulation

Reviewed by the HeyPsych Medical Review Board

Board-certified psychiatrists and mental health professionals

Indications

Primary Indications

Persistent neuropathic pain unresponsive to medication and less invasive therapiesChronic pain after spinal surgeryMotor rehabilitation in selected spinal cord injury patients

Mechanism

Electrical stimulation of the dorsal columns of the spinal cord alters pain signal transmission and may modulate spinal and supraspinal circuits to promote motor function.

Protocol

Preparation

Patient undergoes trial stimulation period to assess benefit before permanent implantation.

Procedure

Placement of trial leads into the epidural space under fluoroscopic guidance
External pulse generator connected for trial phase (5–7 days)
If successful, surgical implantation of permanent leads and pulse generator

Frequency: Continuous stimulation with adjustable parameters

Duration: Long-term therapy with follow-up programming sessions

Total Treatment Time: Implant surgery plus ongoing maintenance

Equipment

Implantable pulse generator
Epidural leads (percutaneous or paddle)
External programmer for parameter adjustments

Session Structure

Pre-Session

Trial period lead placement and patient education.

Treatment Phase

Continuous electrical stimulation via implanted device.

Post-Session

Follow-up visits for device programming and troubleshooting.

Expected Outcomes

Immediate

Pain relief during trial period

Short Term

Significant reduction in chronic pain
Improved quality of life

Long Term

Sustained pain reduction
Possible motor function improvement in SCI

Side Effects

common

Lead migration

Limitations

High upfront cost; effectiveness depends on patient adherence and device maintenance.

Cost Considerations

typical session cost: N/A (implant surgery cost varies widely)

total treatment cost: $20,000–$50,000 including device and surgery

insurance coverage: Often covered for chronic pain indications; experimental for motor recovery

cost effectiveness: High for select chronic pain patients

Special Populations

Clinical Notes

Trial stimulation is essential before permanent implant to ensure benefit.
Programming adjustments may be needed over time for optimal effect.
Device battery replacement required every 5–10 years.
