Abstract: Objective To evaluate the test-retest reliability and validity of the 3-dimensional Digital Goniometer for Cervical (3DDGC) in measurement of cervical range of motion. Methods 39 healthy participants were measured of cervical range of motion 2 times in 1 hour with 3DDGC by one observer, and with cervical range of motion (CROM) device once. The intraclass correlation coefficient (ICC) of test-retest and the Pearson correlation coefficient between devices were caculated. The measurement errors were evaluated with standard er-ror of mean (SEM). Results The ICC was 0.89 of 3DDGC as the cervical rotation to the left, and it was 0.90-0.98 of the other directions, with the SEM of 2.07-3.85° . The Pearson correlation coefficient was 0.73-0.92, with the SEM of 1.66-3.17° . Conclusion 3DDGC is valid and reliable in test-retest in measuring cervical range of motion, which need more research clinically.
