  • For the Patient

    What is the VMA™?

    VMA™ (Vertebral Motion Analysis) is an FDA-cleared, noninvasive and painless test that uses fluoroscopy to capture x-ray videos of your spine in motion. These videos are then used to produce measurements of the movement between the vertebra in your spine. This provides your physician with a wealth of information about your spine movement, resulting in a more thorough diagnosis.

    How does the VMA™ work?

    VMA™ technology measures spine motion using special equipment that guides each patient through prescribed movement sequences, such as bending forward, backward and side-to-side. Once the images are obtained, they are processed and analyzed using advanced computer software technology. The measurements compiled by this software are then used to generate detailed reports for your physician.

    VMA™ Patient Testing Experience

    The technologist will conduct a “test run” of each bending sequence prior to taking the videos with the C-Arm (a special piece of the X-ray machine that moves around you without contacting your body). You will be positioned in one of our patented patient normalizers. The normalizers are used to guide your movements in a gentle, consistent manner. These movements should not be uncomfortable and the equipment will guide you effortlessly through the test. The same devices are used to conduct both lumbar and cervical exams. If at any time you experience discomfort, you can press a STOP button that will immediately stop the normalizer’s motion.

    How long will the VMA™ test take?

    The testing procedure will take approximately 30 minutes for lumbar procedures and 15 minutes for cervical procedures. Please arrive early and allow plenty of time to locate the testing facility.

    How do I prepare for the VMA™ test?

    • Arrive 15 minutes prior to the appointment
    • Dress comfortably in loose-fitting clothing with no metal or zippers
    • Health permitting, please refrain from eating or drinking 4 hours prior to your exam

    Introducing the VMA™

    For over 70 years the flex/ex x-ray has been considered a standard of care for assessing instability. Due to its high level of variability, the standard flex/ex test can not provide the surgeon with a complete representation of the patient’s spinal instability. This often leaves the surgeon with incomplete and sometimes misleading results (data on file at Ortho Kinematics, Inc.)

    Spine surgeons want and need a more accurate and precise way to assess spinal instability. Ortho Kinematics strongly believes the VMA™ is the first functional test that can help surgeons make more informed clinical decisions.

    VMA™ Results Delivery

    VMA™ reports are delivered to the surgeon within hours via a HIPAA-compliant cloud-based system. Reports can be viewed on any computer, tablet or smartphone.

    Reversing Surgical Coverage Denials

    Coverage denials for fusion surgery are routinely made due to the absence of tangible instability data. The VMA™ report provides defensible data in the assessment of instability.
