Comparative Study
A minimal clinically important difference was derived for the Roland-Morris Disability Questionnaire for low back pain.
To compare methods commonly used to derive minimal important differences and recommend a rule for defining patients as clinically improved on the low back pain-specific Roland-Morris Disability Questionnaire (RMDQ). ⋯ A minimal clinically important difference is derived that is clinically relevant, incorporates the measurement error of the RMDQ, and allows subjects with different grades of severity to improve.

Use of multicontact electrodes and programmable implanted pulse generators has increased the efficacy of spinal cord stimulation for pain. Some investigators find dual column electrodes advantageous for difficult-to-treat axial low back pain, but we have reported significantly improved measures with a single percutaneous midline electrode vs. dual percutaneous electrodes and even better results with an insulated, 1 × 4, midline electrode. ⋯ Compared with the 2 × 8, the 1 × 4 resulted in marginally better patient-rated (109%, p = 0.06) and computer-calculated pain/paresthesia overlap (107%, p = 0.17); higher scaled amplitude to cover the low back (106%, NS); and significantly lower voltage (78%, p = 0.0004), increased extraneous coverage (141%, p = 0.0000), and improved symmetry (25%, p = 0.001). Thus, we observed no significant technical advantage for the insulated 2 × 8 in treating axial low back pain.

Are lifestyle-factors in adolescence predictors for adult low back pain? A cross-sectional and prospective study of young twins.
With more than half of the population experiencing low back pain (LBP) before the age of 20, research must focus on young populations. Lifestyle-factors might be important elements of prevention, since they are modifiable in nature. Therefore, the objective of the present study is to investigate the association between smoking, alcohol consumption and overweight in adolescence and 1) present LBP (cross-sectionally) and 2) the risk of future LBP (longitudinally). ⋯ Several of the Bradford Hill criteria for causality were fulfilled for smoking whereas the crucial aspect of temporality was missing for alcohol consumption and overweight. The twin-control study failed to confirm a statistically significant link between smoking and LBP.

Validation of a translated, culturally adapted questionnaire. ⋯ The Spanish version of the FABQ has good comprehensibility, internal consistency, and reliability. It cannot be analyzed parametrically, but only nonparametrically. The total FABQ is at least as valid as its subscales and simpler to score, making it more suitable for routine clinical use.

What is the clinical evidence base for McKenzie therapy in management of back pain? ⋯ This review provides evidence that McKenzie therapy results in a decrease in short-term (<3 months) pain and disability for low back pain patients compared with other standard treatments, such as nonsteroidal anti-inflammatory drugs, educational booklet, back massage with back care advice, strength training with therapist supervision, and spinal mobilization. No statistical differences were found between McKenzie therapy and other therapies at intermediate-term (3-12 months) follow-up. Data are insufficient on long-term (>12 months) outcomes or outcomes other than pain and disability (eg, quality of life). To date, no authors have compared McKenzie therapy with placebo or no treatment. Also, few data are available on the McKenzie method and its effect on neck pain. Future researchers should focus on these issues.
