Psychosocial factors are known to affect recovery from acute low back pain. The factors with the greatest influence and the optimal methods of measurement and interpretation have not been established. The purpose of this study was to examine baseline psychosocial variables and their ability to predict prolonged work restrictions. ⋯ Fear-avoidance beliefs about work was the psychosocial factor that could best be used to predict return to work in patients with acute work-related low back pain. Examination of fear-avoidance beliefs may serve as a useful screening tool for identifying patients who are at risk for prolonged work restrictions.

Multicenter Study
Evaluation of the presence of sacroiliac joint region dysfunction using a combination of tests: a multicenter intertester reliability study.
The authors examined the intertester reliability of assessments made based on a composite of 4 tests of pelvic symmetry or sacroiliac joint (SIJ) movement that are advocated in the literature for identifying people with SIJ region dysfunction. "Sacroiliac joint region dysfunction" is a term used to describe pain in or around the region of the joint that is presumed to be due to malalignment or abnormal movement of the SIJs. ⋯ Reliability of measurements obtained with the 4 tests appears to be too low for clinical use. Given the measurement error found in this study, the authors suspect it is likely that either the proper treatment technique will not be chosen based on the test results or the intervention will be applied to the wrong side. The 4 tests probably should not be used to examine patients suspected of having SIJ region dysfunction, although the role of therapist training in use of the procedures is unclear.

Case Reports
Impairment-based examination and disability management of an elderly woman with sacroiliac region pain.
The purpose of this case report is to describe the use of a cluster of sacroiliac tests in conjunction with an impairment-based model of examination, diagnosis, and management of sacroiliac region pain. ⋯ This case illustrates the use of an impairment-based model for examination and management of an elderly patient with what appeared to be sacroiliac joint dysfunction.

Clinical Trial Controlled Clinical Trial
Is base of support greater in unsteady gait?
We investigated dynamic interfoot distance (IFD) throughout the gait cycle in people with unsteady gait caused by vestibulopathy and in people without known neuromuscular pathology. We expected that the subjects with unsteady gait would use a greater IFD than subjects without neuromuscular pathology and that this IFD would be correlated with other measures of locomotor stability. ⋯ Gait at preferred speed permitted the unsteady subjects and the comparison subjects to select similar IFD values, but at the cost of slower gait in the unsteady subjects. When required to walk at a "normal" pace of 120 steps/min, subjects with vestibulopathy increased their IFD. These data suggest that wide-based gait alone cannot differentiate between subjects with and without balance impairments. Base of support and other whole-body kinematic variables are mechanical compensations of vestibulopathic instability. Further studies are needed to determine whether development of active control of these whole-body control variables can occur after vestibular rehabilitation.

Multicenter Study Comparative Study
A comparison of five low back disability questionnaires: reliability and responsiveness.
The aim of this study was to examine 5 commonly used questionnaires for assessing disability in people with low back pain. The modified Oswestry Disability Questionnaire, the Quebec Back Pain Disability Scale, the Roland-Morris Disability Questionnaire, the Waddell Disability Index, and the physical health scales of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) were compared in patients undergoing physical therapy for low back pain. ⋯ Measurements obtained with the modified Oswestry Disability Questionnaire, the SF-36 Physical Functioning scale, and the Quebec Back Pain Disability Scale were the most reliable and had sufficient width scale to reliably detect improvement or worsening in most subjects. The reliability of measurements obtained with the Waddell Disability Index was moderate, but the scale appeared to be insufficient to recommend it for clinical application. The Roland-Morris Disability Questionnaire and the Role Limitations-Physical and Bodily Pain scales of the SF-36 appeared to lack sufficient reliability and scale width for clinical application.
