The aim of this study was to assess the associations of overweight and obesity with lumbar radicular pain and sciatica using a meta-analysis. We searched the PubMed, Embase, Scopus, and Web of Science databases from 1966 to July 2013. We performed a random-effects meta-analysis and assessed publication bias. ⋯ Associations were similar for men and women and were independent of the design and quality of included studies. There was no evidence of publication bias. Our findings consistently showed that both overweight and obesity are risk factors for lumbar radicular pain and sciatica in men and women, with a dose-response relationship.

Systematic review and meta-analysis. ⋯ There is evidence of short-term efficacy (moderate for pain and small for function) of opioids to treat CLBP compared with placebo. The effectiveness and safety of long-term opioid therapy for treatment of CLBP remains unproven.

To observe the effect of different intensities of manual acupuncture (MA) stimulation on mechanical pain thresholds (PTs) and the expression of phosphorylated extracellular signal-regulated kinases (p-ERK) in lumbar spinal dorsal horn regions in rats with neuropathic mirror-image pain, so as to explore its mechanisms underlying analgesia. ⋯ Strong MA-stimulation can alleviate neuropathic mirror-image pain in SNL rats, which is closely related to its effect in down-regulating the expression of p-ERK in the bilateral spinal dorsal horn regions.
