Abstract: The purpose of this discussion is to review the methods utilized to calculate the intraclass correlation coefficient (ICC) as well as indications on the interpretation and application of the statistic in the assessment of reliability. The index result of the ICC and several examples of clinical and research applications of the ICC are given with respect to the reliability of isokinetic testing.
