Eligibility
Inclusion criteria
Inclusion criteria: 1. 18 years or older 2. Presence of non-specific LBP without the presence of another condition to explain the pain (ie. cancer, primary musculoskeletal conditions, sciatica) 3. Chronic NsLBP defined as pain persisting for >12 weeks, with pain occurring >4 days/week 4. Non-specific LBP as defined topographically and temporally by the Delphi definition 5. Average weekly pain intensity exceeding 6/10 on VAS scoring 6. LBP that causes severe disability, as defined by the Modified Oswestry Low Back Pain Disability Questionnaire (MODI) 7. Pain may radiate down the buttocks or backs of legs but must not radiate below the knees 8. In patients with features of more widespread, non-specific pain, the low-back pain must be the predominant complaint of pain and the pain intensity of these other pains should not exceed 3/10 on VAS scoring
Exclusion criteria
Exclusion criteria: 1. Pregnant or breastfeeding patients 2. Patients with immune deficiency or taking immune modulating drugs 3. Patients with an acute systemic disorder 4. Language other than English as first language
