Sažetak
Some authors defend the idea that orthopedic instability, occlusal interferences, and the presence of muscular and/or articular unilateral pain, that are so common in patients with temporomandibular disorders, should necessarily lead to a marked asymmetry in the functioning of the masticatoy muscles and as this asymmetry is quantified in the electromyographic records it could be of great use in diagnosis.
AIM OF THE WORK: The purpose of our study was to determine if muscular function in dysfunctional patients is more asymmetrical than in healthy individuals, in order to use this clinical signal in the diagnosis of craniomandibular disorders.
METHOD: We carried out electromyographic tests on a group of 22 patients, who had previously been diagnosed as suffering from a temporomandibular dysfunction. After submitting them to Helkimo test, we compared the results of the electromyographic tests with a control group comprising 19 healthy individuals.
MATERIAL: For the electromyographic tests we used a K6-I electromyograph, which allowed us to calculate the average electromyographic activity generated by each one of the muscles monitored, in registers of 15 seconds in length.
RESULTS: There are significant differences in the means and medians of both groups. The asymmetry index variable discriminates the individuals that belong to each group.
CONCLUSIONS: The results of the comparative study indicated that muscular asymmetry is more pronounced in dysfunctional patients. However, the discrimination capacity of the Asymmetry Index variable should be combined with that of other electromyographic
variables in order for it to be used as a diagnostic criteria in Cranio-Mandibular Dysfunctions.
