Sacral Nerve Root Stimulation (SNS) was compared with Peripheral Subcutaneous Field Stimulation (PSFS). SNS attenuated pain 50 – 60% at low stimulation with good patient satisfaction.
PERIPHERAL SUBCUTANEOUS FIELD STIMULATION VS SACRAL NERVE ROOT STIMULATION IN THE MANAGEMENT OF REFRACTORY COCCYGODYNIA. (PRELIMINARY REPORT)

IASP poster PM 366, Montreal 2010
- severe cases
- refractory to radiofrequency denervation
- “sander quad lead was inserted via a retrograde approach to stimulate the S4 & S5 Sacral Nerve Roots”
- Peripherally implanted leads were prone to migration, needed higher voltager to stimulate and gave 30-40% reduction in VAS
- Sacral Nerve Root Stimulation gave 50-60% relief as low voltages and was met with high patient satisfaction.
Comment – from what I understand, scaral nerve root stimulation is a simple procedure. I believe they are done at the pelvic pain clinic at Foothills hospital in Calgary.
