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.

Psychopathology and the rehabilitation of patients with chronic low back pain disability.
Recent research has clearly demonstrated the important role that psychopathology and other psychosocial factors can play in chronic low back pain disability (CLBPD). The purpose of this study was to evaluate whether diagnosed psychopathology is a significant limiting factor in the successful rehabilitation of patients with CLBPD. One hundred fifty-two CLBPD patients (97 men, 55 women) were given a structured psychiatric interview for official DSM-III-R diagnosis of psychopathology upon entering an intensive 3-week functional restoration treatment program. ⋯ They were subsequently tracked for 1 year after program completion, with treatment outcome being defined as return-to-work status at this 1-year time period. Results demonstrated that, though more than 90% of patients obtained at least one Axis I diagnosis, and more than 50% obtained at least one Axis II diagnosis, neither type nor degree of psychopathology were significantly predictive of a patient's ability to successfully return to work. These prospective study results suggest that if a treatment program is structured to appropriately manage psychopathology, as is the case of an intensive functional restoration program, then psychopathology does not have to interfere with successful treatment outcome.

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
