Randomized Controlled Trial Comparative Study
Qigong versus exercise versus no therapy for patients with chronic neck pain: a randomized controlled trial.
Randomized controlled trial. ⋯ Qigong was more effective than no treatment in patients with chronic neck pain. Further studies could be designed without waiting list control and should use a larger sample to clarify the value of qigong compared to exercise therapy.

Cross-sectional population-based study using administrative databases, census data, and surveys of orthopedic/neurosurgeons, family physicians (FPs) and patients in Ontario, Canada. ⋯ Prior studies have not addressed the role of patient enthusiasm for surgery. Although patients and FPs had variable enthusiasm for surgery, surgeon enthusiasm was the dominant potentially modifiable factor influencing surgical rates. Prevalence of disease and community resources were not related to surgical rates. Strategies targeting surgeon practices may reduce regional variation in care and improve access disparities.

Retrospective descriptive study. ⋯ There is correlation between residual cord size, cerebrospinal fluid remaining anterior to the cord, presence of cord signal changes in the T2-weighted images, and neurologic deficit; however, none were predictive of outcome. There was no significant correlation found between ambulatory status and the presence of an epidural abscess, kyphotic angle, or vertebral body destruction.

Randomized Controlled Trial
Effective dose of peri-operative oral pregabalin as an adjunct to multimodal analgesic regimen in lumbar spinal fusion surgery.
A prospective, randomized, controlled, and double-blind trial. ⋯ Perioperative administration of pregabalin 150 mg before and 12 hours after surgery, but not 75 mg, significantly reduced opioid consumption and the use of additional pain rescue for 48 hours after surgery without significant side effects in patients undergoing spinal fusion surgery.

In vivo validation during functional loading. ⋯ The 3D cervical spine motion can be precisely measured in vivo with submillimeter accuracy during functional loading without the need for bead implantation. Fusion instrumentation did not diminish the accuracy of kinematic and arthrokinematic results. The semiautomated model-based tracking technique has excellent repeatability.
