Yolŋu with Machado–Joseph disease: Exploring communication strengths and needs
Purpose: Yolŋu are Aboriginal Australians from northeast Arnhem Land in the Northern Territory (NT). Machado–Joseph disease (MJD) prevalence in the NT Aboriginal population is the highest in the world. Yolŋu living with progressive dysarthria associated with MJD could benefit from augmentative and alternative communication (AAC). However, there are no aided AAC systems in Yolŋu languages. This research aimed to explore the views of Yolŋu with MJD…
Sound-field Amplification: Enhancing the Classroom Listening Environment for Aboriginal and Torres Strait Islander Children
Sound-field amplification is an educational tool that allows control of the acoustic environment in a classroom. Teachers wear small microphones that transmit sound to a receiver system attached to loudspeakers around the classroom. The goal of sound-field amplification is to amplify the teacher's voice by a few decibels, and to provide uniform amplification throughout the classroom without making speech too loud for normal hearing children. This…
Physiological features of dysarthria in Friedreich's ataxia
Due to the paucity of literature concerning the motor speech impairment in persons with Friedreich's ataxia (FA), the aim of this study was to investigate the perceptual and physiological features of dysarthria in a 30-year-old male with FA, 22 years post diagnosis. The four speech subsystems were comprehensively evaluated using physiological measures of respiratory (Respitrace), laryngeal (Laryngograph, Aerophone II), velopharyngeal (Nasometer) …
Voice changes following androgenic hormone treatment in women
Androgenic medications have been known to cause changes to the vocal folds and to voice quality for many decades. One such androgen is Danazol, a synthetic derivative of testosterone. Although altered perceptual voice features have been consistently reported following treatment with Danazol, objective measurements of the voice changes have been limited. The current study incorporates a comprehensive assessment battery of vocal function including …
Velopharyngeal dysfunction following severe traumatic brain injury in childhood: A physiological and perceptual analysis
The velopharyngeal function of 23 subjects who had sustained a traumatic brain injury (TBI) in childhood was assessed using both accelerometric and perceptual techniques. Horii Oral Nasal Coupling (HONC) indices were obtained from the production of nasal and non-nasal sounds, words and sentences. These values were compared with those of a non-neurologically impaired control group matched for age and sex. The TBI group exhibited significantly incr…
Towards a better understanding of the role of subcortical nuclei participation in language: The study of a case following bilateral pallidotomy
Pallidotomy is a neurosurgical procedure that involves the creation of discrete lesions within the globus pallidus, in an attempt to relieve the akinetic and hyperkinetic symptoms associated with Parkinson's disease (PD). Populations undergoing such procedures provide an unprecedented opportunity to test operative theoretical models of subcortical participation in language. This paper reports the effect of circumscribed lesions of the globus pall…
Assessment of dysarthric speech: A case for a combined perceptual and physiological approach
Traditionally, the assessment of dysarthric speech has mainly involved the use of perceptual evaluation measures. The inherent inadequacies of this method of assessment have resulted in the development of a range of instrumental assessment techniques to provide more objective analyses of the underlying physiological impairments of the speech apparatus in individuals with a dysarthric speech disturbance. The aim of the current study was to highlig…
