Functional magnetic resonance imaging has been used to investigate nociceptive processes in patients with chronic pain. However, the results may be confounded with changes in neurovascular coupling induced by chronic pain. The objective of this study was to examine spinal neurovascular coupling in a rat model of chronic back pain induced by muscle inflammation. ⋯ Nevertheless, neurovascular coupling was comparable between groups on days 14 and 28, whether neurovascular coupling was calculated with the amplitude or the area under the curve of SCBF responses (all P > 0.2). These results indicate that spinal hemodynamic changes reflect neuronal activity in this animal model, although the time course of SCBF responses is affected by chronic inflammatory back pain. This warrants a careful use of spinal functional magnetic resonance imaging in animal models and patients with chronic back pain.

To evaluate the effectiveness of low-dosed outpatient biopsychosocial interventions versus active physical interventions on pain intensity and disability in adults with nonspecific chronic low back pain. ⋯ This meta-analysis suggests that low-dosed PCBI has favorable effects in terms of disability and pain intensity compared to active physical treatments alone. All conducted meta-analyses indicate that biopsychosocial interventions produce better outcomes than active physical treatment alone. Therefore, we strongly recommend decision makers and clinical practitioners to analyze how psychosocial elements can be introduced into outpatient (low-dosed) CLBP interventions.

Persistent nonspecific back pain is now established as a biopsychosocial phenomenon that can be meaningfully affected by individuals' cognitions, emotions, lifestyle factors and family and social relationships. Recent guidelines for the treatment of adolescents with persistent nonspecific back pain, as well as those for youth with mixed chronic pain, strongly recommend interdisciplinary care in which adolescents receive treatment for both mind and body. The objective of this scoping review was to examine the interventions evaluated in randomized trials for adolescents with persistent back pain to determine whether they correspond to these guidelines and to reveal future research priorities. ⋯ This scoping review describes in detail the interventions included in randomized trials for adolescents with persistent, nonspecific back pain. The review is important because it reveals discrepancies between those interventions and the interventions recommended for this population.
