Pain associated with diabetic peripheral neuropathy (DPN) is treated medically with gabapentin/pregabalin, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors1 which are often not satisfactory long-term. Spinal Cord Stimulation (SCS) is an effective alternative per 3 randomized controlled trials (RCTs)2,3,4. We reviewed and compared 3 published RCTs2,3,4 comparing SCS to conventional treatments for painful DPN in subjects with mostly type 2 diabetes (Table 1). Study outcome measures included a composite primary endpoint where patients could be identified as treatment responders by reduction in pain diary scores or Patient Global Impression of Change, ≥50% reduction in VAS measurement for pain, and a compound primary endpoint of ≥50% reduction in pain score and no neurologic decline. EQ5D questionnaires were used to assess Quality of Life. The difference in treatment success between SCS and control for the primary endpoint in the Intention-to-Treat populations ranged from 52 - 58%. Improvement in EQ5D index scores at 6 months ranged from 0.124 - 0.380. The similarity of outcomes in 3 RCTs2,3,4 demonstrate that SCS is an effective treatment modality for DPN pain compared with conventional medical approaches. Patients from 1 study4 have been followed-up to 18 months8 and patients in another2 up to 10 years9 with similar outcomes, demonstrating long-term benefits of SCS for patients with painful DPN.
