Comparative Study
Minimal clinically important change of the Neck Disability Index and the Numerical Rating Scale for patients with neck pain.
Prospective, single-cohort study. ⋯ The estimated MCIC should be used as an indication for relevant changes in clinical practice. Using the optimal cutoff point of the ROC curve, false positives and false negatives are equally weighted; and if there are no objections doing so, the optimal cutoff point of the ROC curve may be a good choice.

Randomized Controlled Trial Comparative Study
Artificial disc versus fusion: a prospective, randomized study with 2-year follow-up on 99 patients.
A total of 115 patients were randomized in a 1:1 ratio to a Bryan artificial disc replacement (56) or an anterior cervical fusion with allograft and a plate (59). ⋯ The Bryan artificial disc replacement compares favorably to anterior cervical discectomy and fusion for the treatment of patients with 1-level cervical disc disease. At the 2-year follow-up, there are statistically significant differences between the groups with improvements in the NDI, the neck pain and arm pain VAS scores, and the SF-36 physical component score in the Bryan disc population.

Randomized Controlled Trial Multicenter Study Comparative Study
The effects of lifestyle intervention for hypertension on low back pain: a randomized controlled trial.
Randomized controlled trial. ⋯ Multidisciplinary lifestyle intervention aimed to reduce hypertension is not effective at reducing prevalence of low back pain or disability. However, in the subgroup of persons doing moderate or heavy work, the intervention seemed to reduce prevalence of low back pain during the 1-year follow-up.

Randomized Controlled Trial Comparative Study
One-year follow-up comparison of the effectiveness of McKenzie treatment and strengthening training for patients with chronic low back pain: outcome and prognostic factors.
A randomized controlled trial with multivariable analyses of prognostic factors. ⋯ Poor long-term outcome of exercise therapy for chronic low back pain can be explained by a number of patient-related factors. Different prognostic factors were associated with different outcomes. These factors were more important in determining outcome than the exercise-programs studied.

Comparative Study
From chronic low back pain to disability, a multifactorial mediated pathway: the InCHIANTI study.
Clinicoepidemiologic study in the Chianti area (Tuscany, Italy). ⋯ The cross-sectional association between LBP and self-reported disability, in specific tasks is modulated by performance measures. Specific performance-based tests that explore the functional consequences of LBP may help design specific interventions of disability prevention and treatment in patients with LBP.
