抄録

We developed a simultaneous analyzing system for a total evaluation of TMJ sounds and condylar movement in TMD patients.<br>•We introduced this system and studied proper conditions for quantitative evaluation of condylar movement-velocity.<br>The outline is described below.<br>•This system was mainly developed for the purpose of diagnosis of TMJ and analysis of condylar micro-movement. An analyzing program including quantitative TMJ sounds, condylar movement, and the time-relationship between them was made.<br>•To accurately evaluate the location of sounds with various frequencies and TMJ micro-sounds, the digital filtering method was employed.<br>•It was proved that the pathway of condylar movement was not affected by some analyzing conditions, but velocity was strongly affected.<br>•A higher sampling frequency and lesser smoothing yielded a more marked difference of velocity between normal controls. It was therefore necessary to be at least over 100Hz of sampling frequency and below 7 points of smoothing to differentiate velocity between normal controls and patients.
