Comparação dos níveis de oxigênio muscular durante a execução de um protocolo de exercícios para resistência à fadiga em mulheres hígidas e com desordens temporomandibulares

Abstract

Temporomandibular Disorder (TMD) is a collective term for pain and dysfunction of the masticatory muscles and temporomandibular joint, characterized functionally by the limitation of jaw movement and may involve joint noise, pain, change in sensitivity and muscle activity. Factors such as poor sleep quality, increased depression, anxiety and nutritional deficit are some of the consequences provided by TMD, which significantly affects quality of life. A low extraction of oxygen in muscles responsible for mastication is detected in volunteers who have TMD and physical exercise may be an option to help control these levels, since it provides an increase in blood flow in the muscles involved. Knowing this, this study will be conducted in order to compare the levels of muscle oxygen saturation (SmO2) of the masseter after the execution of fatigue resistance exercises in healthy women with temporomandibular disorders. A total of 88 women were included, divided into 58 members for the TMD group and 30 for the healthy women group, and the masseter muscle oxygen saturation levels were evaluated before and after the execution of the fatigue resistance exercise protocol. The collected data were analyzed using the IBM Statistical Package for the Social Sciences (SPSS) version 26.0. For analyses between groups, the Kruskal-Wallis test was used and for comparison of the time factor, the Friedman test. There was no difference between the SatO2 of the masseter muscle between the groups after application of the exercise protocol, but there was a decrease in levels when the volunteer was evaluated before and after application.
