Reliability of Measuring the Cervical Sagittal Translation Mobility with a Simple Method in a Clinical Setting

Table 3

The inter-rater agreement for the total cervical translation mobility in the sagittal plane. Mean values, standard deviations (SD), medians, minimum and maximum ranges of motion for rater A and B and for the differences between A and B are presented, as well as the limits of agreement (individual reference interval (mean ± 1.96 * SD)), the 𝑃 values for the systematic differences, and the intraclass correlation coefficients (ICC).
