Demographic and clinical characteristics of patients with low back pain in primary and secondary care settings in Southern Denmark.
To describe and compare the demographic and clinical characteristics of patients with acute or chronic low back pain across all health care settings treating this condition.Design and setting: Concurrent prospective survey registration of all consecutive consultations regarding low back pain at general practitioners, chiropractors, physiotherapists, and the secondary care spine centre in Southern Denmark. ⋯ The demographic and clinical characteristics of patients with low back pain differ considerably across the health care settings treating them.KEY POINTSThe study describes the symptoms and clinical findings of patients with low back pain consulting the Danish health care system in all its settings.Patients with chiropractors were youngest, while those with physiotherapists were the oldest and most frequently female.First consultations in general practice were generally with the least symptomatic patients while those returning for a subsequent consultation had more severe disease including more sick leave compared to patients in the other primary care settings.Our findings call for caution when generalizing between health care settings for patients with low back pain.

Meta Analysis
NEUROMUSCULAR ADAPTATIONS TO EXPERIMENTALLY INDUCED PAIN IN THE LUMBAR REGION: SYSTEMATIC REVIEW AND META-ANALYSIS.
Experimental pain models are frequently used to understand the influence of pain on the control of human movement. In this systematic review, we assessed the effects of experimentally induced pain in the lumbar region of healthy individuals on trunk muscle activity and spine kinematics. Databases were searched from inception up to January 31, 2022. ⋯ By contrast, activity of erector spinae, deep multifidus, and transversus abdominis was reduced during postural perturbation tasks. Reduced range of motion of the lumbar spine in the presence of pain was supported by low quality of evidence. Given the agreement between our findings and the adaptations observed in clinical populations, the use of experimental pain models may help to better understand the mechanisms underlying motor adaptations to low back pain.

Randomized Controlled Trial
High-Definition Transcranial Infraslow Pink-Noise Stimulation Can Influence Functional and Effective Cortical Connectivity in Individuals With Chronic Low Back Pain: A Pilot Randomized Placebo-Controlled Study.
Pain can be regarded as an emergent property of multiple interacting, dynamically changing brain networks and thus needs a targeted treatment approach. A novel high-definition transcranial infraslow pink-noise stimulation (HD-tIPNS) technique was developed to modulate the key hubs of the three main nociceptive pathways simultaneously, ie, the pregenual anterior cingulate cortex (pgACC) (descending inhibitory pathway), the dorsal anterior cingulate cortex (dACC) (medial nociceptive pathway), and both somatosensory cortices (S1) (lateral nociceptive pathway). This study aimed to evaluate safety and verify whether a single session of HD-tIPNS may disrupt functional and effective connectivity between targeted cortical regions. ⋯ The Clinicaltrials.gov registration number for the study is ACTRN12621001438842.

MRS was shown to reliably quantify relative levels of degenerative pain biomarkers, differentiating painful versus non-painful discs in patients with chronic discogenic low back pain (DLBP), and this correlates with surgical success rates. We now report results based on more patients and longer follow-up. ⋯ More successful, sustained outcomes were obtained when surgically treating chemically painful discs identified by NOCISCAN-LS post-processed disc MRS exams. Results suggest that NOCISCAN-LS provides a valuable new diagnostic tool to help clinicians better select treatment levels.

Chronic low back pain is difficult to treat and despite increased spending on health services, clinical outcomes for people with low back pain have not improved. Innovative, large scale initiatives seem necessary to stem the cost of low back pain. Psychological health contributes to the development and persistence of chronic low back pain and psychological interventions are important in the management of low back pain. ⋯ The current evidence is limited to cross-sectional associations, but strong preclinical data clearly shows the potential negative impacts of maternal separation on rodent pup health that compels consideration in human populations. PERSPECTIVE: The benefits stemming from enhanced child development include stable emotional foundations, possibly improving psychological health and low back pain management in the future. This perspective raises questions for future studies - within the context of low back pain, what ingredients bolster stable psychological health? And are these ingredients influenced by parental leave?
