[The reliability of axiographic tracings]

The aim of this study was to compare the within- and between-session reliability of axiographic tracings. 22 patients with different degrees of TMJ dysfunction were examined using the SAS system. Within one and between two axiographies, respectively, the most frequent evaluation according to an index assignment was "very good". However, when tracings between two axiographies were compared the evaluations "extensive", "low", or "none" could be found in a considerable number of cases. These findings indicate a loss of reliability of irregularities between two axiographies. Testing of differences in reliability between different types of movement showed no significant effects.
