Investigators

The patients were independently evaluated for the study after a calibration meeting. The prerequisite of the calibration process was the study of the original publication describing the guidelines for the assessment of condylar registration¹⁹. Based on this, 10 registrations that were not included in the later study were discussed and concluded in a structured Delphi process. In the following, four practitioners analyzed the motion recordings from two specialized institutions in Hamburg (M.O.A., T.P., L.K.) and Leipzig (H.A.J.). The Hamburg-based examiners worked in a Center specializing in TMD diagnosis and therapy from which the data originated. In contrast, the Leipzig-based examiner worked in a university dental clinic where he was responsible for the TMD consultations. The agreement among the examiners' findings was determined by calculating Fleiss' Kappa [κ].
