Chronic inflammation increases the production of cytokines and activates proinflammatory pathways which may lead to nonspecific low back pain (LBP). We systematically reviewed the literature to investigate whether inflammatory biomarkers are associated with nonspecific LBP. ⋯ Our findings support the notion of a positive association between inflammatory biomarkers and nonspecific LBP, specifically for CRP, TNFs, and IL-6. Although further high quality longitudinal studies are needed to confirm these findings and evaluate the magnitude of these associations, our findings suggest a role of inflammation in the pathogenesis of nonspecific LBP.

The Illness Invalidation Inventory (3*I) was designed to assess individuals' perceived invalidation regarding chronic pain experiences. However, no study has yet investigated the psychometric properties of the 3*I among individuals with chronic low back pain (CLBP). Given the personal and societal impact of CLBP and the potential for invalidation associated with this condition, the current study sought to examine the psychometric properties of the 3*I among individuals with CLBP. ⋯ The 2-factor model of the 3*I "family members" subscale identified in the current study reflects previous findings and extends the psychometric validity of the 3*I to a US multiethnic sample of individuals with CLBP.

A 21-year-old male Army basic trainee was evaluated in a direct-access physical therapy clinic for left-sided low back pain. Following examination, radiographs and a bone scan were ordered. ⋯ The patient underwent a tissue biopsy and subsequently was diagnosed with Ewing's sarcoma. J Orthop Sports Phys Ther 2020;50(5):276. doi:10.2519/jospt.2020.9109.

Modulation of pain perception by oxytocin (OXT) has attracted increased scientific and clinical interest. Neural mechanisms underlying these effects are poorly understood. In this study, we aimed to investigate the effects of intranasally applied OXT on intrinsic neural activity in patients with chronic low back pain (cLBP). ⋯ Our data suggest significant oxytocin-related modulation of intrinsic regional activity and neural network strength in patients with chronic low back pain and healthy controls. In patients, distinct regions of the pain matrix may be responsive to modulation by oxytocin. Therapeutic effects of oxytocin for improved pain treatment need to be further investigated.
