Design outcomes

Primary

MeasureTime frame
1. Pain measured using the numerical rating scale (NRS) at baseline, injection 1, injection 2, and 1 month, 3 months, 6 months and 12 months post-activation of the ReActiv8 device 2. Functional disability measured using the Oswestry Disability Index (ODI) at baseline and 3 months, 6 months and 12 months post-activation of the ReActiv8 device

Secondary

MeasureTime frame
1. Health-related quality of life measured using the EQ-5D at baseline and 3 months, 6 months and 12 months post-activation of the ReActiv8 device 2. Medication use recorded using questionnaire at baseline and 3 months, 6 months and 12 months post-activation of the ReActiv8 device 3. Work status recorded using questionnaire at baseline and 3 months, 6 months and 12 months post-activation of the ReActiv8 device 4. Physical function measured using the sit-to-stand and 5-minute walk tests at baseline and 3 months, 6 months and 12 months post-activation of the ReActiv8 device
