Abstract
Objective: The Cartesian Optoelectronic Dynamic Anthropometer (CODA) motion analysis system is a new instrument that measures 3-dimensional joint movement. The study aimed to investigate the reliability and validity of the CODA motion analysis system in assessing the cervical range of motion in healthy people.
Methods: A total of 41 healthy participants were included. Movements in 3 planes (flexion and extension, right and left lateral bending, and right and left axial rotation) were measured by using the CODA motion analysis system. The results for flexion-extension and lateral bending movements were compared with those obtained by a standard inclinometer. Intraobserver and interobserver reliability and validity were assessed using the intraclass correlation coefficient (ICC) method. SE of measurement (SEM) and minimal detectable change (MDC) values were also calculated to identify the measurement errors.
Results: High interobserver reliability (ICC range, 0.89-0.94) and validity (ICC range, 0.73-0.89) were found for all 3 planes, while the intraobserver reliability (ICC range, 0.76-0.92) was high, except for right lateral bending (ICC, 0.76) and left axial rotation movements (ICC, 0.84). All SEM and MDC values for intraobserver, interobserver, and criterion validity studies were less than 5° and 10°, respectively. Percentage of SEM of ≤10% and percentage of MDC of ≤30% were obtained for all variables.
Conclusion: The CODA motion analysis system is a highly reliable, noninvasive, easy-to-use, and reproducible 3-dimensional device for measuring cervical range of motion. It demonstrated good reliability for flexion-extension and lateral bending movements.
