Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate if BurstDRTM SCS is clinically non-inferior to conventional SCS in patients already implanted with an internal pulse generator (IPG) capable of delivering both conventional and burst SCS | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate patient satisfaction and quality of life with BurstDRTM SCS compared to conventional SCS. Gather data in order to calculate the adequate sample size of a future randomised controlled trial. | — |
