Randomized Controlled Trial Comparative Study Clinical Trial
Assessing change over time in patients with low back pain.
This study compared the ability of the Roland-Morris (RM), Oswestry (OSW), and Jan van Breemen Institute (JVB) pain and function questionnaires to detect change over time. ⋯ Based on the latter finding, we believe the RM questionnaire may be the preferred instrument for assessing change over time in patients with low back pain.

This study describes recent United States trends and regional variations in the management of low back pain. ⋯ Rapidly increasing surgical rates and wide geographic variations suggest the need for a more consistent approach to back problems.

This study is a prospective cross-sectional analytic study. ⋯ The zygapophysial joint is an important source of pain but the existence of a "facet syndrome" must be questioned.

In a prospective, single-blinded study, the incidence of false-positive screening tests for sacroiliac joint dysfunction was investigated using the standing flexion, seated flexion, and Gillet tests in 101 asymptomatic subjects. ⋯ This study suggests that asymmetry in sacroiliac motion due to relative hypomobility as determined by these tests can occur in asymptomatic joints. Obviously, one should not rely solely on these tests to diagnose symptomatic sacroiliac dysfunction.

Randomized Controlled Trial Clinical TrialLymphocyte profiles in patients with chronic low back pain enrolled in a clinical trial.
Our earlier findings suggest that patients with musculoskeletal complaints have lower numbers and percentages of natural killer (NK) cells than asymptomatic subjects. This study examines patient lymphocyte profiles, as a secondary outcome measure, in a trial of manipulative therapies to treat chronic low back pain (LBP) of mechanical origin. ⋯ This is the first report of lymphocyte profiles in patients with diagnosed chronic LBP. Our finding of a lower percentage of NK cells in these patients confirms our earlier finding that patients with musculoskeletal problems have a lower percentage of NK cells than do asymptomatic subjects. However, manipulative therapy was not shown to have a clinically significant effect on either the absolute n
