2. Place the base of the inclinometer on a horizontal flat surface (deskor table top) to obtain the neutral "0" position. With the subject in thesupine position, place the base of the inclinometer at the base of the headin a position identical to that used for measuring cervical rotation, but inline with the patient's nose. Record the rotational ankylosis angle.3. Consult the Ankylosis Section of Table 53 to determine theimpairment of the whole person.Example: A cervical region with ankylosis at 20° right rotation isequivalent to an impairment of 20% of the whole person.Consult Table 50 if radiographic methods are chosen to determineimpairment due to ankylosis.3.3d Impairments Due to Range of Motion Abnormalities-Thoracic RegionFlexion and ExtensionThoracic flexion/extension is a relatively limited motion with a degree ofextension significantly determined by the subject's posture and the degreeof fixed kyphosis in the thoracic spine. For this reason, in this region ofthe spine it is more convenient to substitute a slightly different concept formeasurement of flexion/extension. Instead of extension, the subject ismeasured in the "military brace" posture to obtain the angle of minimumkyphosis. Following this, the angle of thoracic flexion is obtained by fullyflexing the thoracic spine from the "military brace" position. The angle of
