Early evidence suggests human assumed central sensitization (HACS) is present in some people with acute low back pain (LBP). Factors influencing individual variation in HACS during acute LBP have not been fully explored. We aimed to examine the evidence for HACS in acute LBP and the contribution of brain-derived neurotrophic factor (BDNF), clinical, psychological and demographic factors to HACS. ⋯ Human assumed central sensitization (HACS) is present in acute low back pain (LBP) but factors contributing to individual variation are not fully explored. This study investigated the relationship between factors such as brain derived neurotrophic factor (BDNF) and HACS in acute LBP. Our findings indicate that HACS was present in specific LBP subgroups but BDNF was unrelated to HACS. Combinations of BDNF genotype, demographic and psychological factors explained a small proportion of the variation in sensory measures during acute LBP.

Self-efficacy is one of the important factors affecting chronic diseases. In the current epidemiological context of low back pain (LBP), LBP self-efficacy has become a topic of great practical interest for researchers. However, no bibliometric analysis related to LBP self-efficacy has been performed to date. The purpose of this study was to conduct and explore the current state of research in LBP self-efficacy from 1980 to 2021, by using bibliometric analysis and scientific mapping. ⋯ The volume of literature on LBP self-efficacy has increased linearly over the past 41 years and will continue to increase. The field of study has become more refined. This bibliometric analysis provides valuable support for future directions and research trends in LBP self-efficacy.

Observational Study
External Validation of SpineNet, an Open-source Deep Learning Model for Grading Lumbar Disc Degeneration MRI Features, Using the Northern Finland Birth Cohort 1966.
This is a retrospective observational study to externally validate a deep learning image classification model. ⋯ In this study, SpineNet has been benchmarked against expert human raters in the research setting. It has matched human reliability and demonstrates robust performance despite the multiple challenges facing model generalizability.

Low back pain (LBP) is highly prevalent and disabling for older adults. Movement-evoked pain is an emerging measure that may help to predict disability; but is not currently a part of geriatric LBP clinical care. This study tested the safety and feasibility of a new Movement-Evoked Provocation Test for Low Back Pain in Older Adults (MEPLO). We also compared associations between movement-evoked pain via 2 different scoring methods and disability-associated outcomes. ⋯ This study shows the safety and feasibility of testing movement-evoked pain in older adults with persistent LBP, and its potential superiority to traditional pain measures. Future studies must validate these findings and test the extent to which MEPLO is implementable to change with geriatric LBP standard of care.

Symptomatic postoperative lumbar epidural hematoma (PLEH) may lead to poor outcomes even after evacuation. This study aimed to verify the short-term clinical outcomes after the evacuation of PLEH and to clarify the characteristics of the patients with poor postoperative outcomes. ⋯ Delayed evacuation of PLEH can lead to poor postoperative outcomes after lumbar spine surgery. Moreover, patients with poor outcomes remained with postoperative leg numbness. Early evacuation of symptomatic PLEH is key to avoid poor outcomes and persistent leg numbness.
