impairment of the whole person.Example: A cervical region with ankylosis at 20° right rotation isequivalent to 20% impairment of the whole person.Consult Table 50 (p. 79) if radiographic methods are chosen to determineimpairment due to ankylosis.Thoracolumbar Region-Flexion and Extension Abnormal Motion1. Place the patient in the neutral position (Figure A8).2. Center the goniometer axis at the midlumbar level (Figure A8).Record the goniometer reading with the upper arm parallel to T12 and thelower arm parallel to the skin mark over the sacral midpoint.3. Flexion: With patient bending as far forward as possible (FigureA9), follow the range of motion. Note that the lower, "stable" arm of thegoniometer moves as well as the upper. Record the angle that subtendsthe arc of motion keeping both arms parallel to the T12 and sacral skinmarks.
