To report the clinical course of older adults presenting for a new primary care visit for back pain, no healthcare visit for back pain within the prior 6 months, by describing pain intensity, disability, pain interference, and resolution of back pain over 12 months. ⋯ The majority of older adults in primary care practice settings presenting with a new visit for back pain have persistent symptoms, disability, and interference over 12 months of follow-up. Future research is needed to identify risk factors for persistent symptoms and effective interventions.

To investigate the successive change of low back pain (LBP) prevalence in childhood and adolescence and to examine the associations between LBP and extracurricular sports activities (ECSA) or body mass index (BMI) using a 6-year birth cohort study. ⋯ The point and lifetime prevalence of LBP and the rate of more severe LBP increased as the pupils got older. BMI may be associated with LBP in childhood and adolescence.

Comparative Study
A comparison of abdominal muscle thickness changes after a lifting task in subjects with and without chronic low-back pain.
Using ultrasound imaging, the abdominal muscles' response to the back extensor muscle fatigue was assessed in subjects with chronic low-back pain (CLBP). ⋯ Ultrasound imaging technique can provide critical information about the effect of fatigue on spinal muscle activation and consequently about the stability of the spine. As a more applicable and easy technique, ergonomists can use ultrasound imaging in musculoskeletal system assessment in worker populations in future studies.

Recent data show that the thoracolumbar fascia can be a source of pain. However, the spinal neuronal mechanisms underlying pain from a pathologically altered fascia are unknown. The present study aimed at finding out how dorsal horn neurons react to input from a chronically inflamed thoracolumbar fascia. ⋯ One of the prominent findings was the appearance of new receptive fields in deep tissues of the hindlimb. Together with the expansion of the spinal target region of fascia afferents into the segment L3, the appearance of new receptive fields is a possible explanation for the spread of pain in patients with non-specific low back pain.
