To evaluate the reliability and validity of the simplified Chinese version of the Quebec Back Pain Disability Scale (SC-QDS). ⋯ The SC-QDS has good internal consistency, test-retest reliability, and construct and discriminative validity. The SC-QDS is appropriate for clinical and research uses with Chinese-speaking patients with LBP in mainland China.

A prospective, observational study. ⋯ A single ESI in postmenopausal women adversely affects BMD of the hip. This is in conjunction with a rise in bone remodeling activity, as evidenced by an increase in bone-specific alkaline phosphatase and CTX. In addition, when compared with an age-matched control population, our study population exhibited a greater decline in BMD. Our findings show that epidural administration of corticosteroids has a deleterious effect on bone, which should be considered when contemplating treatment options for radiculopathy. The resulting decrease in BMD, while slight, suggests that ESIs should be used with caution in those at a risk for fracture.

Chronic pain and depression are highly comorbid; however, the longitudinal link is only partially understood. This study examined direct and indirect effects of chronic back pain on depression using path analysis in a general population sample, focussing on cognitive mediator variables. ⋯ These results support the cognitive mediation hypothesis which assumes that psychological variables mediate the association between pain and depression. The importance of helplessness/hopelessness is of relevance for the treatment of patients with chronic back pain.
