17. CRMA can quantitatively analyze the extent of the ligamentous laxity.

        CRMA is Computerized Radiographic Mensuration Analysis, or CRMA. It is also called “digitized X-ray.” The term “mensuration” simply
        means “the measurement of geometric quantities.” Medical and chiropractic doctors have, for nearly 100 years, been measuring the
        translational and angular malpositioning of vertebrae. CRMA is used to measure radiographics (X-ray) using a computer. CRMA
        provides for accurate, computerized measurement of the malpositioning of vertebrae due to ligamentous laxity.

        CRMA is a valuable tool to all health care practitioners, in that it provides quantifiably definite measurement. It assists in arriving
        establishing a differential diagnosis and the development of an appropriate treatment plan.

        The measurements of translation in the cervical spine in excess of 1 mm is considered to be abnormal movement of the cervical
        spine. Measurement in excess of 7 degrees of angular variation is considered to be abnormal.

                                                                               28
        Abnormal shifting of the Atlas on the Axis of more than 1.7 mm is considered abnormal .
        It provides substantiation for pain that might otherwise be labeled as “secondary gain,” “somatoform disorder,” or “faking”,
        “malingering.”

        For attorneys, it is a “blockbuster” development. It provides objective evidence of ligamentous injury that has been the major cause
        of chronic pain and disability in CAD injuries.

         DIGITAL MOTION X-RAY REVEALS SEVERE SPINAL INSTABILITY OF C1 LATERAL MASS SLIDING OF THE EDGE OF C2 AND THE INCREASE/DECREASE OF
