- Change in Oswestry Disability Index (ODI) [ Time Frame: 1 year ]Comparison of 1-year change from baseline in ODI between Treatment and Control. ODI is measured on a scale of 0 to 100 where a higher score is a better outcome.
- Change in Low Back Pain Numerical Rating Scale (LBP NRS) [ Time Frame: 1 year ]
Comparison of 1-year change from baseline in LBP NRS between Treatment and Control.
NRS is measured on a scale of 0 to 10 where a higher score is a better outcome.
- Change in EQ-5D [ Time Frame: 1 year ]
Comparison of 1-year change from baseline in EQ-5D between Treatment and Control.
EQ-5D is measured on a scale of -0.5 to 1.0 where a higher score is a better outcome.
