This study aimed to assess the frequency of temporomandibular disorders (TMDs) in patients with axial spondyloarthritis (axSpA) compared with the healthy individuals. We systematically searched PubMed, Embase, Scopus, Web of Science, CINAHL, and Google Scholar databases from their inception until 2022, without language restriction. A standardized dataset was used to extract data from the observational studies. Patients were required to have axial spondyloarthritis and clinical and/or radiographic evidence of temporomandibular joint dysfunction. Meta-analysis was performed with a random effects model. A systematic review was registered under number CRD42020206283. We identified seven relevant studies, which provided data for 745 patients and 216 temporomandibular disorders events. The combined odds ratio (OR) showed that the risk of temporomandibular disorders in individuals with axial spondyloarthritis was higher than the control group (pooled OR = 5.26, 95% CI 2.50-11, 06; p < 0.02; I 2  = 58%). Also, these individuals do not appear to refer possible temporomandibular joint symptoms to the rheumatologist or dentist. The results of this systematic review and meta-analysis suggest that patients with axial spondyloarthritis have an increased frequency of temporomandibular disorders. TMDs seem to be secondary to postural alterations rather than direct involvement of the temporomandibular joints (TMJs)., (© 2022 Wiley Periodicals LLC.)

Purpose: To describe the primary effects of electromyographic biofeedback therapy on swallowing via a systematic review., Methods: A blind search was carried out by two researchers in the PubMed and Bireme platforms and in the Medline, Lilacs, SciELO, PsycINFO, CINAHL, and Web of Science databases, and the journal articles identified therein were evaluated for inclusion in the study. Original articles associated with the theme were selected with no population-, region-, or language-associated limits. A protocol was created for this study with the following points: author, year, place, number and characteristics of participants, activities evaluated, instruments used, and main results. The PEDro scale was used to analyze the quality of the studies., Results: Among the 686 articles identified in the combined searches, 566 were duplicates. A total of 65 articles were discarded after the title and abstract were read, and a further 29 articles were discarded after the full text was read, yielding a total of six articles for inclusion. In summary, the results lead us to believe that positive effects on the laryngeal lifting capacity, improved swallowing functions, and increased excursion and maximal elevation of the hyoid bone, may be directly related to this method of therapy., Conclusions: Adjunctive therapeutic protocols with biofeedback electromyography exert positive effects on swallowing function.
