Abstract

Background: Joint hypermobility (JH) allows a range of motion beyond normal physiolo­gical limits and is associated with connective tissue disorders. Its impact on vocal and lary­ngeal function remains underexplored. Objective: To examine the relationship between JH and vocal and laryngeal alterations in studies from the last decade. Methods: A systematic review was conducted across five databases (Web of Science, Scopus, PubMed, ScienceDi- rect, SciELO) using the keywords “hypermobility”, “voice”, and “larynx” Studies in Engli­sh, Spanish, or Portuguese analyzing vocal and/or laryngeal aspects in individuals with JH were included. Results: Ten studies were selected. The findings indicate that individuals with JH frequently present dysphonia, vocal fatigue, and perceptual alterations. Instru­mental evaluations revealed glottic closure deficits, supraglottic compression patterns, and structural changes. Reports emphasized the negative impact on quality of life, particularly among professional voice users. Conclusion: The findings highlight the complexity of vocal and laryngeal alterations in individuals with JH and underscore the importance of incorpo­rating JH assessments into the evaluation of patients presenting with dysphonia.
