Application of transcutaneous nervous electric stimulation in individuals with temporomandibular dysfunction: randomized clinical trial

Abstract

INTRODUCTION: Physiotherapy has several resources for the treatment of temporomandibular dysfunction, such as transcutaneous electrical nerve stimulation (TENS), but with many variations in protocols and dosimetric parameters. OBJECTIVE: To analyze the efficacy of transcutaneous electrical nerve stimulation (TENS), with fixed phase duration and frequency, in the analgesia and functionality of temporomandibular disorders. METHODS: The sample consisted of 20 individuals, separated in a treated group and placebo, during 2 weeks of treatment, evaluated by Questionnaire on Mandibular Symptoms and Oral Habits, analyzing pain and joint function. RESULTS: Both groups presented reduction in pain and general score, compared to the pre-intervention moment, for the function, only the TENS showed a reduction of the values, but there were no differences between the groups. CONCLUSION: TENS was not different from placebo in pain control, however, it promoted functional improvement in volunteers.
