Low back pain (LBP) is a common and major health problem. Although it is known that psychosocial factors are important predictors of LBP outcome, some factors, including financial compensation, have not been fully studied in Japan. This cross-sectional study aimed to examine the association between LBP compensation (workers' compensation and automobile insurance claims) and lifetime experience of chronic LBP and back pain disability (chronic disabling LBP) in a Japanese adult population. ⋯ The prevalence of compensated LBP was low. However, a history of compensated LBP was significantly associated with experiencing chronic disabling LBP.

Neck pain is a common health problem that restricts activities of daily living. The Neck Disability Index (NDI) was developed to assess disability in patients with neck pain. The normative score and the cut-off value are mandatory to assess an individual patient or a certain patient group for clinically important neck pain with disability, by distinguishing it from nonsignificant pain. The objective of the present study was to determine the normative score and the cut-off value of the NDI. ⋯ The normative score and the cut-off value of the NDI were determined. Our cut-off value is potentially useful in evaluating the therapeutic effectiveness of various interventions for neck pain.

The sitting position has become the most common posture in today's workplace. In relation to this position, kinematic analysis of the lumbar spine is helpful in understanding the causes of low back pain and its prevention. ⋯ This study showed that LLA decreased by approximately 50 % and PT increased by approximately 25 % in the sitting position compared with the standing position. No significant gender differences were observed for LLA, SS, and PT in the standing position. In the sitting position, however, LLA and SS were markedly larger for women.

Randomized Controlled Trial
Interscalene brachial plexus block for scapular and upper chest pain due to cervical radiculopathy: a randomized controlled clinical trial.
Animal experiments have shown that one of the pathways for pain originating from the cervical spine is the sympathetic trunk. However, there have been few reports regarding the cervical pain pathway and efficacy of interscalene brachial plexus block for upper limb, scapular and chest pain originating in the cervical spine in clinical cases. The purpose of the present study was to clarify the efficacy of interscalene brachial plexus block for upper limb, scapular and chest pain. ⋯ Interscalene brachial plexus block is useful for upper limb, scapular and chest pain due to disorders of the cervical spine. The scapular and chest pain pathway is more likely to be interrupted by an interscalene brachial plexus block that causes a stellate ganglion block compared to an interscalene brachial plexus block without stellate ganglion block.

Comparative Study
Treatment of unstable posterior pelvic ring fracture with percutaneous reconstruction plate and percutaneous sacroiliac screws: a comparative study.
The aim of this study is to compare the clinical effects of percutaneous reconstruction plate and percutaneous sacroiliac screws in treatment of unstable posterior pelvic ring fracture. ⋯ The clinical effect of the two methods is similar in treatment of Tile C pattern posterior pelvic ring fracture. However, the percutaneous reconstruction plate has lower risk of damaging nerves and blood vessels than the percutaneous sacroiliac screws. Moreover, intraoperative fluoroscopy is rarely performed.
