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.
