Single-Area Versus Multiple-Area Passive Recharge Burst During Spinal Cord Stimulator Trials: An Independent Prospective Randomized, Double-Blind Study.

In 30 seconds

This randomized controlled trial evaluated the effectiveness of single-area versus multi-area passive recharge burst therapy in a neurostimulation naive population for chronic pain management. The study found that multi-area programming led to an average pain relief of 67% by trial's end, with an 87% conversion rate to permanent implantation.

Key findings

• Average VAS pain score decreased from 70.2 to 22.2 by trial's end.
• Pain relief improved from 53% at mid-trial to 67% at the end.
• 87% of patients converted from trial to permanent implantation.
• 83% of patients completed the trial on multi-area burst therapy.

Why it matters

The findings suggest that multi-area passive recharge burst therapy can significantly enhance pain relief and improve various quality of life metrics in patients with chronic pain, potentially leading to higher success rates in neurostimulation trials.
