Repercusiones vocales del síndrome de hiperlaxitud articular

Abstract

IntroductionJoint hypermobility is a frequent syndrome in children and women, its impact on the musculoskeletal system are diverse and occur with different degrees of severity. Its consequences on vocal function have been studied sparingly, often preventing its optimal clinical approach. ObjectiveTo describe the vocal behaviour of women with joint hypermobility syndrome. Material and methodA sample of 40 women with a medical diagnosis of joint hypermobility syndrome was studied. The assessment was carried out using video laryngeal stroboscopy, electroglottography, acoustic analysis, intensity and vocal overload tests. ResultsIn video laryngeal stroboscopy it was possible to demonstrate less muscle development, vibratory asymmetry and arytenoid imbalance. In the electroglottography, the CQ of the sample was 0.4±0.05. The average maximum intensity was 85.8±6.2dB and the maximum phonatory time was 11.8±3.1s. In the tasks of the overload the sample showed rapid fatigability. ConclusionsThe vocal behaviour of the subjects suffering from joint hypermobility syndrome implies glottic insufficiency, due to a lack of muscular development of the vocal folds.
