The purposes of this study were to determine intra and interrater reliability for Root's method for measuring first ray position and mobility for experienced and inexperienced examiners. This study was a single-blind prospective reliability study examining experienced and inexperienced examiners in their measurements of first ray position and mobility. A total of 36 subjects and four examiners (two experienced and two inexperienced) participated in this study. Five recorders recorded all data. Subjects came in on two separate occasions, one week apart, so that examiners could evaluate their bilateral first ray position and mobility, using Root's technique for both measurements. Kappa correlation coefficients with an alpha level set at P ≤ 0.05 were used to determine intra and interrater reliability. There were four significant correlations found for intrarater reliability and three significant correlations found for interrater reliabilities. Results indicated poor to fair agreement for all measurements. More research is indicated to further determine the usefulness of this measurement technique.
