Randomized Controlled Trial
Parenteral corticosteroids for Emergency Department patients with non-radicular low back pain.
Although not recommended for low back pain, the efficacy of systemic corticosteroids has never been evaluated in a general low back pain population. To test the efficacy of systemic corticosteroids for Emergency Department (ED) patients with low back pain, a randomized, double-blind, placebo-controlled trial of long-acting methylprednisolone was conducted with follow-up assessment 1 month after ED discharge. Patients with non-traumatic low back pain were included if their straight leg raise test was negative. ⋯ The change in NRS between discharge and 1 month differed between the two groups by 0.6 (95% confidence interval -1.0 to 2.2), a clinically and statistically insignificant difference. Disability, medication use, and healthcare resources utilized were comparable in both groups. Corticosteroids do not seem to benefit patients with acute non-radicular low back pain.

Randomized Controlled Trial
The effectiveness of graded activity for low back pain in occupational healthcare.
Low back pain is a common medical and social problem associated with disability and absence from work. Knowledge on effective return to work (RTW) interventions is scarce. ⋯ Graded activity was not effective for any of the outcome measures. Different interventions combined can lead to a delay in RTW. Delay in referral to graded activity delays RTW. In implementing graded activity special attention should be paid to the structure and process of care.

Reliable classification systems and clinical tests are sought for the care of patients with low back pain (LBP). The objectives of this clinical study were to evaluate inter-examiner reliability in the classification of patients with LBP, the influence of radiological findings on the classification and the reliability of some clinical tests. Two examiners independently assessed 50 outpatients with LBP. ⋯ The reliability of clinical tests was good (kappa>0.6) in 6 tests and moderate (kappa>0.4) in 12 tests. Good inter-examiner reliability was found for the SLR test, movement range and sensibility testing with spurs in dermatome areas. We conclude that the KWC for classifying patients with LBP seems to be a reliable classification system depending on a few key observations and that moderate and good inter-examiner reliability can be achieved in several clinical tests in the assessment of LBP.

Randomized Controlled TrialA randomized, single blind placebo controlled clinical trial on the effect of continuous ultrasound on low back pain.
Low back pain (LBP) is a very common problem in primary care and a major cause of disability. There is no evidence for the efficacy of therapeutic modalities such as ultrasound in LBP In a randomized, single blind placebo controlled clinical trial, we aimed to evaluate the effect of continuous ultrasound (US) in patients with non specific LBP Of the fifty eight patients recruited, 10 patients (8 women and 2 men) randomly allocated to ultrasound (n=5) or placebo controlled (n=5) groups. The patients were treated by either US or sham-US for ten sessions, three days per week, every other day. ⋯ Before and after treatment, the mean H reflex latency and Hmax/Mmax ratio, right and left side were similar in the groups (p > 0.05), and no significant changes were observed in the treatment groups (p > 0.05). After treatment, the extension and lateral flexion range of motion significantly increased in the US group (p = 0.04), but the back movements in the placebo group did not show significant changes (p > 0.05). The present study supports the significant effect of US on LBP, and suggests that US may improve the functional ability of patients with non specific low back pain.

Comparative Study
Use of the one-legged hyperextension test and magnetic resonance imaging in the diagnosis of active spondylolysis.
Active spondylolysis is an acquired lesion in the pars interarticularis and is a common cause of low back pain in the young athlete. ⋯ These results suggest that there is a high rate of active spondylolysis in active athletes with low back pain. The one-legged hyperextension test is not useful in detecting active spondylolysis and should not be relied on to exclude the diagnosis. MRI is inferior to bone scintigraphy (with SPECT)/computed tomography. Bone scintigraphy (with SPECT) should remain the first-line investigation of active athletes with low back pain followed by limited computed tomography if bone scintigraphy is positive.
