  1. JPE = Joint position error, CCFT = Cranio-Cervical Flexion Test. 95% CI = 95% confidence interval, ICC agreement = Inter class correlation coefficients. Meandiff_AB = mean difference between examiner A and B, SDdiff_AB = standard deviation of the mean difference between examiner A and B. SEM = standard error of mesuremeant, LOA = Limits of agreements, SDC = smallest detectable change.
