Vertebral motion analysis (VMA) is an imaging technique that uses X-ray technology to create a video of the spine in real-time. This information allows a radiologist to discover injuries in the neck or back that could otherwise go undetected. Unlike static diagnosis images, like X-ray or MRI, VMA uses a device that can examine the spine in real-time.
The spine is an extremely important part of the body, and it is also very complex. Spine conditions including herniated disc degeneration and arthritis can develop due to age and injury, causing problems up and down the neck and back.
In some cases, a physician looking at a static MRI or X-ray may see multiple issues that could be the source of pain. By being able to take a moving image, doctors can see how certain movements affect the joints and discs in the spine while patients report whether or not they are experiencing pain.
