Randomized Controlled Trial Multicenter Study Comparative Study
Adjacent segment motion after anterior cervical discectomy and fusion versus Prodisc-c cervical total disk arthroplasty: analysis from a randomized, controlled trial.
Post hoc analysis of data acquired in a prospective, randomized, controlled trial. ⋯ Adjacent segment kinematics may be altered after ACDF and TDA. Multivariate analysis showed time to be a significant predictor of changes in adjacent segment ROM. No association between the treatment chosen (ACDF vs. TDA) and ROM was observed. Furthermore clinical follow-up is needed to determine whether possible differences in adjacent segment motion affect the prevalence of adjacent segment disease in the two groups.

Randomized Controlled Trial Comparative Study
One-year follow-up in employees sick-listed because of low back pain: randomized clinical trial comparing multidisciplinary and brief intervention.
Randomized clinical trial comparing two interventions in employees sick-listed 3 to 16 weeks because of low back pain (LBP). ⋯ Hospital-based multidisciplinary intervention may be no better than brief intervention to increase RTW and improve health in sick-listed employees with low back pain.
