5-year longitudinal follow-up of patients treated for chronic mechanical low back pain using restorative neurostimulation
Authors' conclusion
Restorative neurostimulation provides robust, sustained improvements in pain, function, and quality of life in patients with CLBP associated with multifidus dysfunction.

- Outcome
- Clinical outcomes: pain (NRS), disability (ODI), health-related quality of life (EQ-5D-5L)
- Follow-up
- 5 years

Main finding
As reported in the abstract
Pain, disability and quality of life, baseline to 5 years
Minimally clinically important change in either pain or disability
82%
Pain remitters (Numerical Rating Scale (NRS) ≤3)
62%
Observational data: associations, not effects.
Further findings
Device usage (therapy utilization, implantable device logs) · 5 years
- Device usage averaged 1106 hours over 5 years, with reductions in usage over time
- Lower usage associated with non-response; causality could not be determined
