Reproducibility and validity of digital inclinometry for measuring cervical range of motion in normal subjects

Abstract

DI-based CROM measurements are reproducible and valid for recording sagittal and frontal plane motions in healthy subjects. The higher range in rotations, relative to the Zebris-based findings, is most probably attributable to the test position. Being relatively cheap, portable and convenient for tester and subject alike, the DI seems to be an effective instrument for assessing CROM.
