DC/TMD Examiner Protocol: Longitudinal Evaluation on Interexaminer Reliability

Table 1

Reliability (intraclass correlation coefficients (ICC)) for opening, lateral, and protrusive movements (mm). ICC calculations based on ICC values between the “reference” and Examiner 1 and the “reference” and Examiner 2 (average measurements).
