Objective discrimination between mandibular open/close excursion patterns: a clinical case report.
The purpose of this clinical case report was to describe the kinematic variables of movement that best discriminated between asymmetrical and symmetrical mandibular excursion patterns in a patient with myogenic temporomandibular dysfunction. Two mandibular movements (deemed to be asymmetrical and symmetrical by both patient and physiotherapist) were each recorded six times on three occasions at six, twelve, and 15 weeks after commencement of an exercise programme. The mandibular movements were captured with a 12-camera Motion Analysis System (Motion Analysis Corp., Santa Rosa, CA) with kinematic variables expressed in six degrees-of-freedom. A two-way analysis of variance (ANOVA) for repeated measures was used to analyze the data. The asymmetrical pattern was characterized by increased axial rotation and decreased sagittal rotation but with no differences in translation values when compared to those of the symmetrical pattern. The results support the clinician's and patient's judgment regarding differences in quality of mandibular excursion patterns made over the course of time.
