Radiography and Clinical Decision-Making in Chiropractic.

The concern over x-ray exposure risks can overshadow the potential benefit of radiography, especially in cases where manual therapy is employed. Spinal malalignment cannot be accurately visualized without imaging. Manual therapy and the load tolerances of injured spinal tissues raise different criteria for the use of x-rays for spinal disorders than in medical practice.

Response to Comment on "Estimating the reproducibility of psychological science".

Gilbert et al. conclude that evidence from the Open Science Collaboration's Reproducibility Project: Psychology indicates high reproducibility, given the study methodology. Their very optimistic assessment is limited by statistical misconceptions and by causal inferences from selectively interpreted, correlational data.

Exploratory evaluation of the effect of axial rotation, focal film distance and measurement methods on the magnitude of projected lumbar retrolisthesis on plain film radiographs.

Objective: The purpose of this exploratory study was to evaluate the amount of error in retrolisthesis measurement due to measurement methods or projection factors inherent in spinal radiography. In addition, this study compared how accurately these methods determine positions of the lumbar vertebrae being studied and the expected projected size of the retrolisthesis.

Methods: Vertebral models were situated in a retrolisthesis position.

Guidelines for the practice and performance of manipulation under anesthesia.

Background: There are currently no widely accepted guidelines on standards for the practice of chiropractic or manual therapy manipulation under anesthesia, and the evidence base for this practice is composed primarily of lower-level evidence. The purpose of this project was to develop evidence-informed and consensus-based guidelines on spinal manipulation under anesthesia to address the gaps in the literature with respect to patient selection and treatment protocols.

Methods: An expert consensus process was conducted from August-October 2013 using the Delphi method.
