Perceptual Characteristics of Adductor Spasmodic Dysphonia [PDF]
Annals of Otology, Rhinology & Laryngology, 2000 The evaluation of perceptual symptoms is one of the mainstays in the diagnostic workup of adductor spasmodic dysphonia (ADSD). The most widely used perceptual rating system is the GRBAS scale. However, with this system, not all audible features of ADSD can be described. Therefore, we extended the GRBAS system by 6 parameters. The aim of this study was

Disfluency in Spasmodic Dysphonia
Journal of Speech, Language, and Hearing Research, 1997This study examined visual analog scaling (VAS) judgments of disfluency by normal listeners in response to oral reading by speakers with spasmodic dysphonia (SD) and by nondysphonic controls, as well as the variables of frequency of occurrence of disfluencies, speaking rate, number of reading errors, and temporal acoustic measures of interword interval

Spasmodic (Laryngeal) Dysphonia
2012Spasmodic dysphonia (SD) is an adult-onset focal dystonia characterized by abnormal vocal cord contractions activated by speech. There are three forms of spasmodic dysphonia. The commonest form, making up about 90% of cases, is adductor dysphonia in which spasmodic adduction of the vocal cords causes interruptions in phonation called voice breaks ...

Botulinum Toxin Treatment for Spasmodic Dysphonia
Acta Oto-Laryngologica, 1993Effective treatment of adductor type spasmodic dysphonia with botulinum toxin injection is presented. Patients showed objective and/or subjective improvement in phonation. The beneficial effect lasted for approximately 3 months. An immediate complication is temporary hoarseness or aphonia, mainly due to diffusion of BT into the adjacent muscles.

Laryngeal Sensory Symptoms in Spasmodic Dysphonia
Journal of Voice, 2023The purpose of this research was to determine whether an association between laryngeal hypersensitivity (LH) and spasmodic dysphonia (SD) exists using the LH Questionnaire (LHQ). This study also explored the prevalence of self-reported upper respiratory infection (URI) at the time of SD onset across SD phenotypes.Individuals with and without SD were ...

Contemporary management of spasmodic dysphonia
Current Opinion in Otolaryngology & Head and Neck Surgery, 2004To review current concept in spasmodic dysphonia management.The standard of care for spasmodic dysphonia in 2004 remains botulinum toxin chemodenervation for symptomatic management. This is supported by a large body of literature attesting to its efficacy in many different hands, particularly for the adductor form of the disorder.

Central Pathology in Spasmodic Dysphonia
Journal of VoiceSpasmodic dysphonia a voice disorder characterized by loss of voluntary control of vocal fold movements during speech production. The pathophysiology is not well understood, but there have been proposed connections to areas within the brain such as the reticular formation surrounding the tractus solitarius, spinal trigeminal and ambiguus nuclei ...
