Randomized Controlled Trial Comparative Study Clinical TrialAre nonspecific practice guidelines potentially harmful? A randomized comparison of the effect of nonspecific versus specific guidelines on physician decision making.
To test the ability of two different clinical practice guideline formats to influence physician ordering of electrodiagnostic tests in low back pain. ⋯ The clarity and clinical applicability of a guideline may be important attributes that contribute to the effects of practice guidelines.

Clinical TrialLong-term exercise adherence after intensive rehabilitation for chronic low back pain.
The purpose of this study was to examine exercise compliance in patients with chronic low back pain (CLBP) after participation in an intensive spine rehabilitation program. ⋯ It is concluded that exercise behaviors can be increased and maintained in CLBP patients without adversely affecting pain or function.

Twenty volunteers and 20 patients with no prior spine surgery had two standing lateral radiographs taken, on the average, 66 months apart and 2 weeks apart, respectively. ⋯ The pelvic radius technique is recommended for evaluating lordosis to the pelvis because this approach provided not only good measurement reliability on standing radiographs for lumbopelvic lordosis, but also determination of pelvic balance over the hips and the option to assess pelvic morphology quantitatively. Lumbopelvic lordosis and pelvic balance were strongly correlative. This finding, along with higher reliability and lower longitudinal variation on repeated radiographs, indicated greater clinical application for these specific measurements.

Mechanical testing of cadaveric motion segments. ⋯ The posterior anulus can be stress shielded by the neural arch in extended postures, but the effect is variable. This may explain why extension exercises can relieve low back pain in some patients.

Cross-sectional magnetic resonance imaging (MRI) study. ⋯ Low back pain is associated with signs of disc degeneration and sciatic pain with posterior disc bulges. Low back pain is strongly associated with occupation.
