Randomized Controlled Trial Comparative Study
Multidisciplinary group rehabilitation versus individual physiotherapy for chronic nonspecific low back pain: a randomized trial.
A randomized trial. ⋯ The results of this study indicate that semilight outpatient multidisciplinary rehabilitation program for female chronic low back pain patients does not offer incremental benefits when compared with rehabilitation carried out by a physiotherapist having a cognitive-behavioral way of administering the treatment.

Low back pain: prediction of short-term outcome of facet joint injection with bone scintigraphy.
To prospectively evaluate use of bone scintigraphy with single photon emission computed tomography (SPECT) for identification of patients with low back pain who would benefit from facet joint injections. ⋯ Bone scintigraphy with SPECT can help identify patients with low back pain who would benefit from facet joint injections.

Randomized Controlled Trial Multicenter Study
Analgesic efficacy and safety of lornoxicam quick-release formulation compared with diclofenac potassium: randomised, double-blind trial in acute low back pain.
NSAIDs are widely used for patients presenting with low back pain. A quick-release formulation of lornoxicam, a potent NSAID from the chemical class of oxicams, offers a faster onset of pain relief compared with the standard tablet formulation. ⋯ Lornoxicam administered as a quick-release formulation was shown to be non-inferior to the equivalent formulation of diclofenac potassium in terms of onset of pain relief and more effective on most of the major standard efficacy outcomes.

Effects of focusing and distraction on cold pressor-induced pain in chronic back pain patients and control subjects.
Previous studies showed equivocal findings regarding the efficacy of focused attention and distraction to experimental pain. This study examined the relative efficacy of these strategies on perception of cold pressor pain in 41 chronic back pain patients and 41 healthy control participants. Participants were randomized to the 2 strategies and then completed a 7-minute cold pressor test. Pain intensity and discomfort ratings were obtained during the task. Participants who completed the first task were asked to complete a second cold pressor task without instructions. Pain and discomfort ratings differed by condition across time. In the distraction condition, pain levels started low but continued to rise throughout the cold pressor immersion, whereas in the focused attention condition, pain levels started higher, rose less quickly, and then decreased from the middle of the task. Focused attention was associated with higher pain and lower completion rates in chronic pain patients compared with healthy control subjects. Focused attention might therefore not be an effective intervention strategy for individuals with chronic back pain. Finally, in the second cold pressor test, patients' pain reports rose more rapidly than those of healthy control subjects. The results of this study can be explained in terms of differences in cognitive appraisal between pain patients and healthy control participants. ⋯ Marked differences were found between chronic back pain patients and control participants regarding focused attention as compared with distraction as a means of coping with cold pressor-induced pain. These differences underline the importance of taking into account previous experience with pain when recommending strategies to cope with painful procedures.

Randomized Controlled Trial Comparative Study
The effect of sedation on diagnostic validity of facet joint nerve blocks: an evaluation to assess similarities in population with involvement in cervical and lumbar regions (ISRCTNo: 76376497).
Zygapophysial or facet joint pain in patients suffering with chronic spinal pain without disc herniation or radiculopathy may be diagnosed with certainty by the use of controlled diagnostic blocks. But, in patients suffering with either lumbar or cervical facet joint pain, even this diagnostic approach may be confounded by false-positives when using a single diagnostic block. It may also be confounded by the administration of anxiolytics and narcotics prior to, or during, the controlled diagnostic facet joint blocks. The effect of sedation on the validity and potential differential results in patients suffering with combined cervical and lumbar facet joint pain has not been evaluated. ⋯ Perioperative administration of sodium chloride, midazolam, or fentanyl can confound results in the diagnosis of combined cervical and lumbar facet joint pain. False-positive results with placebo or sedation may be seen in a small proportion of patients.
