Abstract

Cervical range of motion (ROM) is evaluated in both clinical and research settings. This study's purpose was to determine if ROM data obtained with the OSI CA 6000 Spine Motion Analyser (SMA) from asymptomatic and symptomatic cervical subjects were reliable within and between testers. Cervical ROM was measured in all three planes in 30 adult asymptomatic and 20 adult symptomatic subjects. A standardized protocol was used to fit each subject with the OSI SMA cervical hardware. Subjects were tested in a seated position with the trunk stabilized. Subjects performed four trials of each pain-free cervical motion during testing. The hardware was completely removed and replaced by the same tester and ROM trials in all three planes were repeated for intratester asymptomatic and symptomatic reliability. The same procedure was completed by a second tester for asymptomatic intratester and intertester reliability. Repeated measures analysis of variance and intraclass correlation coefficients (ICC [2,1 and 2 k]) were used to analyse intra- and intertester reliability data. Intratester ICCs were 0.85 or higher (except for flexion 0.76) for asymptomatic subjects and 0. 87 or higher (except for flexion 0.68) for symptomatic subjects for all motions. Intertester ICCs were 0.88 or higher for all motions. Standard error of measurements were less than 3.92 degrees for all motions. Measures of cervical spinal ROM obtained with the OSI SMA showed good intertester reliablity for all motions, and good intratester reliability for all motions with the exception of the motion of flexion for one of the examiners, which showed moderate reliability.
