To identify and critically appraise studies evaluating psychometric properties of functionally oriented diagnostic classification systems for Non-Specific Chronic Low Back Pain (NS-CLBP). ⋯ Multiple low risk of bias studies demonstrate strong inter-rater reliability for OCS classification specifically OCS-MCI subcategory. Future studies with low risk of bias are needed to evaluate reliability and validity of the MCI test battery and the PBA.

Randomized Controlled Trial
Healthcare expenditure and its predictors in a cohort of Australians living with sciatica.
To estimate the healthcare resource utilisation of an Australian cohort of people with sciatica and explore individual-level factors associated with expenditure. ⋯ Our results suggest inefficiency in the use of healthcare resources due to increased healthcare resource utilisation in people with sciatica treated with pregabalin, compared to placebo. Costs of treating sciatica varied based on individual quality of life and socio-economic characteristics.

The clinical significance of Modic changes in low back pain (LBP) is yet to be clarified. Thus, this study aimed to examine the association between Modic changes and LBP after adjustment for confounding factors. ⋯ Type I Modic changes in the lumbar region are significantly associated with LBP. Profiling Modic changes may be helpful to improve targeted treatment of LBP.

Recent animal studies have discovered dysregulation of local inflammatory activity as a novel mechanism to explain fat and connective tissue accumulation in the multifidus muscle in association with intervertebral disc (IVD) degeneration/injury. This study aimed to test whether similar mechanisms are active in humans by investigation of whether expression of inflammatory genes in the multifidus muscle differed between individuals with low and high levels of intra-muscular fat in the muscle. The secondary aims were to compare inflammatory gene expression in the intra-muscular, subcutaneous and epidural fat between groups. ⋯ The results support the hypothesis that IVD degeneration is associated with dysregulation of the inflammatory state of the local multifidus muscle, which provides initial evidence for translation of some, but not all, observations from recent animal studies to humans. Discovery of inflammatory dysregulation in epidural adipose tissue has potential for broad impact on tissue health and LBP symptoms.

To identify low back pain (LBP) trajectories from early adolescence through to early adulthood and to investigate whether sustained levels of elevated subclinical C-reactive protein (CRP) are linked with these LBP trajectories. ⋯ Diagnostic: individual cross-sectional studies with the consistently applied reference standard and blinding.
