Methods: Two examiners made 2 individual measurements of each of the individual cervical ranges of
motion of 23 patients (15 men, 8 women; aged 21 to 42 years) with no cervical symptoms. The patients
were asked to move their necks to end range while they sat upright. The accuracy of the CROM
instrument and SpinT goniometers was assessed with a testing instrument capable of rotating and/or
tilting to preset angles and upon which either device could be positioned.
