Vertebral Motion Analysis - VMA
What is VMA?
VMA stands for Vertebral Motion Analysis, a noninvasive, painless test that uses fluoroscopy to capture X-ray videos of your spine in motion. This enables physicians to make a thorough diagnosis by understanding the measurements of the movement between the bones in your spine. Tri-City Medical Center is 1 of only 7 hospitals in the nation to implement this technology.

How VMA works
This new technology measures spine motion using equipment that guides the patient through prescribed bending patterns, such as forward and backwards and side-to-side. Once the images are obtained, they are processed and analyzed by advanced computer technology to produce measurements and reports, which are then compiled and given to your physicians.
How do I prepare?
Once your physician has ordered the test, you will be contacted by the radiology department to set up a convenient time for your appointment. Please plan to arrive approximately 15 minutes before your exam to fill out paperwork or provide any information necessary for the facility. Plan to wear comfortable, loose-fitting clothing without metal or zippers at your waist, but know that you may be asked to wear a hospital gown for the procedure. Please refrain from drinking or eating anything up to 4 hours prior to the appointment unless you have a medical condition such as diabetes.
What can I experience during the test?
The technician will walk you through a "test run" of the entire process prior to capturing the videos through the fluoroscopy machine. There are two systems that will guide you in bending your spine in a consistent manner. The first device will have you lying on a table flat and will move your body slowly in a controlled motion with your spine. The second device will do the same thing while you are standing. The bending movements should not be uncomfortable and the equipment will guide you effortlessly through the test. If at any time you experience discomfort, you can press a STOP button that gives you control to end the examination.
How long is the test?
The test will take approximately 40 minutes. Please arrive early and allow plenty of time to locate the testing facility.
