Controlled Clinical Trial
The impact of esophagus retraction on early dysphagia after anterior cervical surgery: does a correlation exist?
Prospective study of 92 patients who underwent anterior cervical surgery. Intraoperative esophagus retraction and postoperative dysphagia were recorded and evaluated. ⋯ A correlation between intraoperative pharynx/esophagus retraction and postoperative swallowing disturbances could not be confirmed. The cause of the prevalence of the female gender is unknown. However, the absence of impaired deglutition in the control group suggests that a local phenomenon must be causative of swallowing disturbances following anterior cervical discectomy and fusion.

Cross-sectional comparison of self-reported low back pain (LBP) symptoms and Modic findings on magnetic resonance imaging (MRI). ⋯ Modic changes at L5-S1 and Modic type I lesions are more likely to be associated with pain symptoms than other types of Modic changes or changes located at other lumbar levels.

Randomized Controlled Trial Comparative Study
A comparison of two short education programs for improving low back pain-related disability in the elderly: a cluster randomized controlled trial.
Cluster randomized clinical trial. ⋯ In institutionalized elderly, the handing out of the Back Book supported by a 20-minute group talk improves disability 6 months later, and is even more effective in those subjects with LBP.

Clinical Trial
Provocative discography and lumbar fusion: is preoperative assessment of adjacent discs useful?
A cohort study of clinical outcomes of lumbar fusion patients with preoperative assessment of adjacent levels by provocative discography. ⋯ In this cohort study of chronic LBP patients with an uncertain indication for lumbar fusion, the preoperative status of adjacent levels as assessed by provocative discography did not appear to be related to the clinical outcome after fusion.

This study measured active cervical spine range of motion (ROM) in children ages 3-12 years using 2 methodologies: (1) a cervical spine ROM instrument, and (2) a digital videography based technique. ⋯ This study contributes valuable normative data for pediatric cervical spine ROM in children that can be used as a clinical reference and for biomechanical applications. In children 3-12 years of age, both flexion and rotation increased slightly with age. Of interest, there were no differences in ROM with gender, which contradicts adult literature where females have been shown to have more cervical spine ROM than males.
