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.

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.

In studies evaluating the efficacy of clinical interventions, it is of paramount importance that the functional outcome measures are responsive to clinically relevant change. Knowledge thereof is in fact essential for the choice of instrument in clinical trials and for clinical decision-making. This article endeavours to investigate the sensitivity, specificity and clinically significant improvement (responsiveness) of the Danish version of the Oswestry disability index (ODI) in two back pain populations. ⋯ A minimum clinically important change (MCID) from baseline score was established at 9 points (71%) for PrS patients and 8 points (27%) for SeS patients using ROC analyses. This was dependable on the baseline entry score with the MCID increasing with 5 points for every 10 points increase in the baseline score. We conclude that the Danish version of the ODI has comparable responsiveness to other commonly used functional status measures and is appropriate for use in low back pain patients receiving conservative care in both the primary and secondary sector.

Controlled Clinical Trial
Contribution of nonspinal comorbidity to low back pain outcomes.
To determine the involvement of comorbidity to outcomes in a cohort of acute mechanical low back pain patients. ⋯ Significant ORs were barely greater than 1.00 and were likely the result of the large sample size. The clinical course for comorbid patients, who may seem more complicated at the start of treatment, is just as favorable.

Chronic low back pain (CLBP) is a common and debilitating problem in older adults. Little exists in the literature about primary care physicians' (PCPs') knowledge of and confidence in managing this problem. A self-administered survey was mailed to PCPs in western Pennsylvania to measure knowledge of the evaluation and treatment of common contributors to CLBP in older adults, confidence in diagnosing these contributors through physical examination, and the association between confidence levels and knowledge. ⋯ There was no relationship between knowledge scores and confidence ratings (P > .05 for all comparisons). The results point to a need for more PCP education about CLBP in older adults. It also suggests that accurate needs assessment should not rely on physician confidence ratings alone.
