BACKGROUND: Otological complaints (OC) are highly prevalent in subjects with temporomandibular disorders (TMD) and so is the risk of neck dysfunctions. OBJECTIVE: To evaluate pain, deep neck flexor (DNF) performance, disability, and head and neck posture of individuals with TMD with and without OC. METHODS: In this cross-sectional study, 57 individuals were divided into a group with TMD and OC (n= 31) and a group with TMD without OC (n= 26). Self-reported pain intensity, masticatory and neck muscles pressure pain thresholds, DNF performance, neck disability, and head and neck posture were evaluated. Data were compared between groups using the independent t test and Mann-Whitney test with Bonferroni correction for multiple comparisons. Effect sizes were evaluated using Cohen’s index. RESULTS: The TMD with OC group presented less muscle activation [26 (24–28) vs. 24 (24–26) mmHg; p< 0.05], less endurance [105 (46–140) vs. 44 (28–78) points; p< 0.05], and greater neck disability (8.15 ± 5.89 vs. 13.32 ± 6.36 points; p< 0.05). No significant difference was observed in self-reported pain, head and neck posture, or pressure pain thresholds. CONCLUSION: Individuals with TMD with OC presented decreased DNF performance and increased neck disability compared to individuals with TMD without OC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
