The lumbar vertebral endplate is considered a potential cause of specific low back pain. However, in relation to future research, there is need for a reliable and detailed magnetic resonance imaging (MRI) protocol to be used in the evaluation of vertebral endplate signal changes. ⋯ In this study, we found convincing reproducibility of a detailed evaluation protocol of vertebral endplate signal changes, the "Nordic Modic Classification." The authors recommend that the evaluation protocol should be used in future studies investigating vertebral endplate signal changes.

Comparative Study
Prevalence of lumbar facet arthrosis and its relationship to age, sex, and race: an anatomic study of cadaveric specimens.
An anatomic, epidemiologic study of facet arthrosis in cadaveric lumbar spines. ⋯ Facet arthrosis is a universal finding in the human lumbar spine. Evidence of arthrosis begins early, with more than one half of adults younger than 30 years demonstrating arthritic changes in the facets. The most common arthritic level appears to be L4-L5. Men have a higher prevalence and degree of facet arthrosis than women.

Lumbar and hip movements, before and in response to rapid bilateral arm flexion, were evaluated in 10 people with recurrent low back pain (LBP) and 10 matched control subjects when standing on a flat surface or short base. ⋯ These data suggest that spinal movement is different in people with LBP, and reduced spinal movement in advance of predictable perturbation may be associated with compromised quality of trunk control.

Positional lumbar imaging using a positional device in a horizontally open-configuration MR unit - initial experience.
To evaluate whether positional MR images of the lumbar spine, obtained with a horizontally open-configuration MR unit, demonstrate positional changes of the dural sac, and to assess whether there are significant differences in positional changes between healthy volunteers and patients with chronic low back pain. ⋯ Using a horizontally open-configuration MR unit, positional MR imaging provided position-dependent change of the dural sac. Positional changes at the site of the degenerated disks may be different in patients with and without chronic low back pain.

Randomized Controlled Trial Comparative Study
Comparison of general exercise, motor control exercise and spinal manipulative therapy for chronic low back pain: A randomized trial.
Practice guidelines recommend various types of exercise and manipulative therapy for chronic back pain but there have been few head-to-head comparisons of these interventions. We conducted a randomized controlled trial to compare effects of general exercise, motor control exercise and manipulative therapy on function and perceived effect of intervention in patients with chronic back pain. Two hundred and forty adults with non-specific low back pain 3months were allocated to groups that received 8weeks of general exercise, motor control exercise or spinal manipulative therapy. ⋯ The motor control exercise group had slightly better outcomes than the general exercise group at 8weeks (between-group difference: PSFS 2.9, 95% CI: 0.9-4.8; GPE 1.7, 95% CI: 0.9-2.4), as did the spinal manipulative therapy group (PSFS 2.3, 95% CI: 0.4-4.2; GPE 1.2, 95% CI: 0.4-2.0). The groups had similar outcomes at 6 and 12months. Motor control exercise and spinal manipulative therapy produce slightly better short-term function and perceptions of effect than general exercise, but not better medium or long-term effects, in patients with chronic non-specific back pain.
