Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Low back pain responder rate at 3 months post-activation as compared with Baseline. A responder is defined as *30% low back pain reduction from Baseline without change in opioids. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secundary endpoints: Change in average low back pain from Baseline to 3 months post-Activation (Numeric Rating Scale) Change in average leg pain from Baseline to 3 months post-Activation (NRS) Percent pain relief of low back pain at 3 months post-Activation Percent pain relief of leg pain at 3 months post-Activation Change in low back pain with activity from Baseline to 3 months post-Activation (NRS) Change in leg pain with activity from Baseline to 3 months post-Activation (NRS) Patient global impression of change at 3 months post-Activation Change in disability from Baseline to 3 months post-Activation (ODI v2.1a) Change in quality of life from Baseline to 3 months post-Activation (SF-36v2) Exploratory endpoints: Change in average low back pain from Baseline through 6, 12 months post-Activation (NRS) Change in average leg pain intensity from Baseline through 6, 12 months post-Activation (NRS) Change in low back pain intensity with activity from Baseline through 6, 12 months post-Activation (NRS) Change in leg pain intensity with activity from Baseline through 6, 12 months post-Activation (NRS) Percent pain relief of low back pain through 6, 12 months post-Activation Percent pain relief of leg pain through 6, 12 months post-Activation Change in average daily leg pain intensity (NRS) from Baseline through 3, 12 months post-activation (Diary) Change in average daily low back pain intensity (NRS) from Baseline through 3, 12 months post-activation (Diary) Change in disability from Baseline Visit through 6, 12 months post-Activation (ODI v2.1a) Patient global impression of change through 6, 12 months post-Activation Change in quality of life from Baseline Visit through 6, 12 months post-Activation (SF-36v2) Change in opioid prescription from Baseline through 6, 12 months post-Activation (Concomitant Medications) Health economic endpoint: Economic value of HR-SCS at 12 months post-Activation (RUI, SF-36v2, Concomitant Medications, Proc | — |
