Multicenter StudySensitivity, specificity and predictive value of the clinical trunk muscle endurance tests in low back pain.
To describe the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of five clinical tests used to measure trunk muscle endurance in low back pain. ⋯ It seems that the prone double straight-leg raise test has more sensitivity, specificity and predictive value in low back pain than other tests and could be used as a useful clinical method for testing the spinal muscle endurance to predict the probability of the occurrence of low back pain.

The LBP patient perception scale: a new predictor of LBP episode outcomes among primary care patients.
To describe a new tool designed to capture patients' perception of their low back pain (LBP) episodes-the patient perception scale (PPS) and test its ability to predict episode outcomes. ⋯ The PPS-pt could potentially be used as part of the standard initial patient evaluation of new LBP patients, as a proxy for "yellow flags" (markers of psychosocial risk) where a positive score might be the equivalent to high-risk identification. The apparent advantage of this scale is its brevity and simplicity of administration. The separation, through this scale of pain episodes into simple and complex LBP might be a useful tool for helping direct resources and avoiding chronicity.

Randomized Controlled Trial Multicenter Study
Physiotherapist-directed exercise, advice, or both for subacute low back pain: a randomized trial.
Advice and exercise are widely recommended for subacute low back pain, but the effectiveness of these interventions is unclear. ⋯ In participants with subacute low back pain, physiotherapist-directed exercise and advice were each slightly more effective than placebo at 6 weeks. The effect was greatest when the interventions were combined. At 12 months, the only effect that persisted was a small effect on participant-reported function.

Randomized Controlled Trial Multicenter Study
Results of the prospective, randomized, multicenter Food and Drug Administration investigational device exemption study of the ProDisc-L total disc replacement versus circumferential fusion for the treatment of 1-level degenerative disc disease.
A prospective, randomized, multicenter, Food and Drug Administration-regulated Investigational Device Exemption clinical trial. ⋯ ProDisc-L has been found to be safe and efficacious. In properly chosen patients, ProDisc-L has been shown to be superior to circumferential fusion by multiple clinical criteria.

Multicenter Study Clinical Trial
Efficacy and safety evaluation of once-daily OROS hydromorphone in patients with chronic low back pain: a pilot open-label study (DO-127).
To evaluate the safety, tolerability, and efficacy of once-daily osmotic controlled-release oral delivery system (OROS) hydromorphone in patients with chronic low back pain of moderate-to-severe intensity. ⋯ OROS hydromorphone may be an effective treatment for chronic low back pain of moderate-to-severe intensity. Adverse events were typical of those associated with opioid therapy.
