Low back pain (LBP) is a common clinical problem and is of major socioeconomic importance. However, at the current time, there is little information about the pathogenesis of this disease. Furthermore, treatment option of LBP has not been fully explored.

We invite investigators to contribute original research papers as well as review articles that will stimulate the continuing efforts to understand pathology, epidemiology, diagnosis, and methods of treatment of LBP. Potential topics include, but are not limited to:

• Pathology of low back pain (animals and humans)
• Epidemiology of low back pain
• Diagnosis of low back pain (animals and humans, e.g., genetics, questionnaire, MRI, and block)
• Treatment of low back pain (animals and humans, e.g., rehabilitation, exercise, medication, and surgery)
• New approach for treatment of low back pain (animals and human, e.g., cytokine inhibitor, and disc regeneration)
