Change Since Baseline in Numerical Rating Scale (NRS) for Pain (Overall) Evaluated Separately for Each Study SCS Therapy Primary · Baseline and in-office visit 3, average of 21 days

The purpose of primary endpoint 1 is to evaluate the change since baseline in Numerical Rating Scale (NRS) for pain (overall) for each study SCS therapy. The evaluation of primary endpoint 1 is based on the NRS for pain (overall) obtained at the final study testing visit compared with the baseline measurement obtained prior to initiation of the commercial trial period, for subjects randomized to each study SCS therapy. Numerical Rating Scale (NRS) was collected for overall pain experienced over the past 24 hours on a scale of 0-10, with 0 being No Pain and 10 being Worst Possible Pain.

Inter-therapy Comparison of Change Since Baseline in Numerical Rating Scale (NRS) for Pain (Overall) Primary · Baseline and in-office visit 3, average of 21 days

The purpose of primary endpoint 2 is to provide an inter-therapy comparison of change since baseline in Numerical Rating Scale (NRS) for pain (overall). Primary endpoint 2 analyses includes all participants included in primary endpoint 1 analyses. Numerical Rating Scale (NRS) was collected for overall pain experienced over the past 24 hours on a scale of 0-10, with 0 being No Pain and 10 being Worst Possible Pain.

Change Since Conclusion of Commercial Trial in Numerical Rating Scale (NRS) for Pain (Overall) Evaluated Separately for Each Study SCS Therapy Secondary · In-office visit 1 at approximately 7 days and in-office visit 3 at approximately 21 days, average of 14 days

The evaluation of secondary endpoint 1 will be based on Numerical Rating Scale (NRS) for overall pain experienced over the past 24 hours (scale of 0-10, with 0 being No Pain and 10 being Worst Possible Pain) obtained at conclusion of commercial trial compared to NRS for overall pain at the final study testing visit

Therapy B Spinal Cord Stimulation Parameter Set0.3± 0.32
Investigational Device-related Adverse Event-free Rate Secondary · Baseline and in-office visit 3, average of 21 days

The evaluation of secondary endpoint 2 will be based on the number of subjects free from investigational device-related adverse events assessed at in-office visit 1 (randomization visit) through in-office visit 3 (study completion). The investigational device-related adverse event-free rate was pre-defined within the protocol as the overall rate from all implanted Prospera SCS devices, regardless of randomized therapy output setting (Therapy A or Therapy B).
