ID: 204152 Single Versus Dual Lead Spinal Cord Stimulation Trials

Spinal cord stimulation (SCS) has been used to treat chronic low back pain (LBP) since it was first proposed by Shealy et al. (1). SCS required placing electrodes in the posterior epidural space near the dorsal columns with electrical stimulation delivered at low-frequency 30-60 Hz (LFSCS) with concordant paresthesia elicited in the areas of pain (2). 10 kHz high-frequency spinal cord stimulation (HF10) was introduced and required no paresthesia mapping and used standardized reproducible epidural lead placement. Several studies have shown the clinical superiority of HF10 over LFSCS, including the two SENZA-RCTs(4,5). Since no paresthesia mapping is needed, we wanted to see if single lead trial would be comparable to standard dual lead trial.
