Efeito de exercícios de resistência muscular à fadiga por biofeedback associados ao uso de dispositivo interoclusal no tratamento de desordem temporomandibular miogênica – relato de caso

Abstract

Temporomandibular Disorders (TMD) are multifactorial and cause various signs and symptoms such as joint noises, limitation in range of motion or deviations during mandibular function, pain in the preauricular region, Tempormandibular Joint (TMJ) masticatory muscles. The objective of this study was to evaluate the effects of an 8-week protocol of biofeedback fatigue resistance exercises associated with the use of an interocclusal device in the treatment of myogenic TMD. For this, the patient was initially submitted to the Diagnostic Criteria for Research on Temporomandibular Dysfunction (RDC/TMD), Visual Analog Scale (VAS) and Electromyographic Assessment (EMG) for screening and diagnosis. Thus, a physical therapy treatment based on weekly progression exercises performed twice a week was used, totaling 16 sessions, including evaluations of electromyographic parameters and perceived pain in the first 24 hours and after 4 and 8 weeks after the initiation of the protocol. In conjunction with this training, an interocclusal device was used at night for 90 days, with intervals of 7, 15, 30, 60 and 90 days between dental follow-up appointments for review and occlusal adjustments of the device. At the end of the instituted therapy, the patient was again submitted to RDC/TMD. Combined dental and physiotherapeutic therapies demonstrated effectiveness in symptomatic pain reduction, promoting patient comfort and greater TMJ range of motion, according to the means of evaluation used.
