Traditional methods for the evaluation of in vivo spine kinematics result in significant measurement variability. The purpose of the study was to determine the repeatability of sagittal lumbar intervertebral measurements using a new system for the evaluation of lumbar spine motion. A total of 205 intervertebral levels from 61 patients were retrospectively evaluated in the study.
The measurements using the VMA technology were found to be substantially more precise compared with the manual technique. The study authors wrote, “The VMA system markedly reduced variability of lumbar intervertebral measurements compared with a digitized manual analysis.”
