Reliability of Zygapophysial Joint Space Measurements Made from MRI Scans of Acute Low Back Pain Subjects: Comparison of Two Statistical Methods

摘要

ObjectiveThis purpose of this study was to assess the reliability of measurements made of the zygapophysial (Z) joint space from the MRI scans of subjects with acute low back pain (ALBP) using new equipment and 2 different methods of statistical analysis. If found reliable, the methods of Z joint measurement can be applied to scans taken before and after spinal manipulation in a larger study of ALBP subjects.
