Abstract

The purpose of this study was to determine the interrater and intrarater reliability of a digital inclinometer used to measure cervical spine range of motion in children or infants who have a diagnosis of torticollis. This was a methodological study in which children and infants from one to twenty-four months participated in measurement of cervical range of motion for rotation, lateral bending, and midline alignment with a digital inclinometer. Fifteen measurements were taken by two different testers. Each tester repeated the same fifteen measurements separated by a brief time interval. Intraclass correlation coefficients were calculated for interrater reliability and for intrarater reliability using SPSS 15.0 for Windows. Intrarater reliability demonstrated acceptable limits for one tester for measurements in 3 directions of movement. One tester demonstrated intrarater reliability of a sufficient level for two directions of movement if an average of three measurements is considered. Interrater reliability in general was poor (less than .75) for a majority of the measurements.
