To estimate the societal costs of low back pain with/without radiating leg pain (LBP). LBP is a major burden in terms of both personal suffering and societal costs. ⋯ LBP has an apparent impact on the overall resource use and work loss. The results indicate that there is a high short-term cost increase at the beginning of an LBP episode, but also that the costs decrease in the long term after the LBP symptoms have come to clinical attention.

An epidemiological study of the prevalence rate of inflammatory back pain and axial spondyloarthritis in a university in the south of China.
Inflammatory back pain (IBP) is an important clinical feature for axial spondyloarthritis (SpA). Yet, little is known about their prevalences in China. We conducted an epidemiological study in a university to detect the prevalences of IBP and axial SpA according to the Assessment of SpondyloArthritis International Society (ASAS) criteria. ⋯ For axial SpA, female/male was 4/9(P = 0.014). In southern China, the prevalences of CLBP and IBP were respectively 19.39 and 2.94% in university, and the prevalence of axial SpA was 0.34%. Although more female students had CLBP, males were more likely to suffer from axial SpA.

Previous studies suggest that life satisfaction assessment using the Life Satisfaction checklist (LiSat-11) is a meaningful outcome measure and may play an important role in setting rehabilitation goals in patients with chronic pain. Until now, there was no Japanese version of this questionnaire, and the psychometric properties of the original version of the LiSat-11 have only been investigated using classical test theory approaches. The objective of the present study was to evaluate the psychometric properties of the LiSat-11-J using Rasch analysis in a sample of Japanese people with low back pain (LBP). ⋯ The LiSat-11-J has unidimensionality, acceptable internal consistency, good test-retest reliability, and concurrent validity to the assessment of pain-related disability and psychological factors. However, targeting function and category order were not well. These two components showed improvement by rescoring category, but not sufficient. These results suggest that the LiSat-11-J is not well adequate to apply as an assessment tool of life satisfaction to the patients with LBP.

Intervertebral kinematic assessments have been used to investigate mechanical causes when back pain is resistant to treatment, and recent studies have identified intervertebral motion markers that discriminate patients from controls. However, such patients are a heterogeneous group, some of whom have structural disruption, but the effects of this on intervertebral kinematics are unknown. ⋯ Patients with treatment-resistant nonspecific back pain have greater MSI values than controls, especially if the former have received spinal surgery. However, excessive laxity, translation and MSV are not more prevalent in these patients. Thus, MSI should be investigated as a pain mechanism and for its possible value as a prognostic factor and/or target for treatment in larger patient populations.
