3. After recording the "0" readings first at TI, then over the occiput,ask the subject to produce a full cervical extension and rerecord the anglesat the occiput and T1 sequentially to obtain calculated cervical extensionangle.Note: When extension is near normal, placement of the inclinometer at T1in maximal extension may be impossible, and the examiner must place askin mark over the scapular spine. The "0" reference points are measuredinitially at the scapular spine, then at the occiput in neutral position. Thethird data point is recorded as the inclinometer remains on the occiputwhile the cervical spine is fully extended. The 4 th point is recorded againover the scapular spine.4. Repeat the procedure three times. Only the cervical flexion angleand extension angle need be consistently measured within +/-10% or 5°,whichever is greater The final measurement for impairment evaluation isthe greatest angle measured.5. Consult the Abnormal Motion Section of Table 51 to determine theimpairment of the whole person.
