Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Chronic low back pain and fusion: a comparison of three surgical techniques: a prospective multicenter randomized study from the Swedish lumbar spine study group.
A multicenter randomized study with a 2-year follow-up period and an independent observer was conducted. ⋯ All the fusion techniques used in the study could reduce pain and improve function in this selected group of patients with severe chronic low back pain. There was no obvious disadvantage in using the least demanding surgical technique of posterolateral fusion without internal fixation.

Randomized Controlled Trial Multicenter Study Clinical Trial
Radiography for low back pain: a randomised controlled trial and observational study in primary care.
Lumbar spine radiography has limited use in diagnosing the cause of acute low back pain. Consensus-based guidelines recommend that lumbar spine x-rays are not used routinely. However there have been no studies of the effect of referral for radiography at first presentation with low back pain in primary care. ⋯ Referral for lumbar spine radiography for first presentation of low back pain in primary care is not associated with improved physical functioning, pain or disability. The possibility of minor psychological improvement should be balanced against the high radiation dose involved.

Multicenter StudyPersistent low back pain and sciatica in the United States: treatment outcomes.
Patients with persistent low back pain (LBP) appear to be different in several important ways from patients who have traditionally been classified as patients with acute or chronic LBP, and data on the effectiveness of the treatments prescribed for them are lacking. The aim of the current study was to evaluate the short- and long-term effectiveness of the treatments currently prescribed for these patients. The data reported in this article were gathered as part of a multicenter, prospective, cross-sectional study of patients who were treated for persistent LBP by neurologic and orthopedic surgeons who are recognized specialists in spinal disorders. ⋯ The outcome of surgery for persistent LBP varied from dramatic for one subgroup of surgical patients, to poor for another subgroup of patients. Patients who were selected immediately for surgical treatment improved substantially. Those treated surgically later by study physicians or by physicians not associated with the study fared less well.

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.

2001 Volvo Award Winner in Clinical Studies: Lumbar fusion versus nonsurgical treatment for chronic low back pain: a multicenter randomized controlled trial from the Swedish Lumbar Spine Study Group.
A randomized controlled multicenter study with a 2-year follow-up by an independent observer. ⋯ Lumbar fusion in a well-informed and selected group of patients with severe CLBP can diminish pain and decrease disability more efficiently than commonly used nonsurgical treatment.
