Lingual Kinematics During Speech in Persons with Multiple Sclerosis
Electromagnetic articulography (EMA) was used to examine lingual kinematicsin a heterogeneous group of seven adults with Multiple Sclerosis(MS), including two with relapsing-remitting and five with primary progressiveforms of MS, with the latter group including two participantswith dysarthria. Tongue tip and tongue body movements were tracked astwo sentences, one loaded with alveolar consonants and the other withvelar consonants, were read aloud …

Lingual Kinematics During Sentence Production in Adults with Dysarthria at 6 and 12 Months Post Stroke
The aim of the present study was to investigate lingual kinematics during sentence production in dysarthric individuals. Three males, aged between 35 and 69 years with dysarthric speech post stroke were assessed at 6 months and 12 months post stroke using the electromagnetic articulography AG-200. A group of 15 non-neurologically impaired males, aged between 36 and 72 years (mean = 56.33 years, SD = 15.59) served as the control speakers. Two targ…

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) …
A study of the resolution of paediatric dysphagia following traumatic brain injury: Practical implications for clinicians
Despite the potentially life-threatening complications of dysphagia (Martin, Corlew, Woods, Olson and Golopol, 1994), and the recognized benefits of early and informed intervention in the acute care setting (Mackay, Bernstein, Chapman, Morgan & Milazzo, 1992), limited research exists on the acute phase or the resolution of swallowing impairment in children subsequent to traumatic brain injury (TBI) (Rowe, 1999; Ward and Morgan, in press). The cur…
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 …
Speech outcomes following brainstem tumour in childhood
The perceptual and physiological speech characteristics of two children treated for brainstem tumours were examined. The differential patterns of performance across the speech profiles of both subjects reflect the variability in severity of dysarthria evident in the brainstem tumour population. Each subject's results were compared with a non-neurologically impaired control group. The perceptual profiles were compiled from a perceptual speech anal…
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…
Genetic regulation of laryngeal muscle development and differentiation
The molecular control of the development, differentiation and functional specialization of the intrinsic laryngeal muscles is largely unaddressed. This work begins to address these questions by examining the expression of myosin heavy chain genes and the muscle regulatory factor, Myf-5, in the larynx. We provide here a brief review of gene expression and the genetic control of skeletal muscle development, and report some preliminary findings of u…
Language performance in children treated for brainstem tumour: The impact of radiotherapy
Two female subjects aged between 10 and 12 years, 20 months post high-dose radiotherapy for a low-grade astrocytoma in the brainstem region, were found to have intact language abilities across a wide range of skills including higher-level language and literacy. Subjects were tested using a battery of standardised language assessments covering general receptive and expressive language abilities, confrontation naming, problem solving, complex reaso…
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…
Predicting the understanding of Cantonese connected discourse
Understanding of connected discourse has a high face validity in estimating an individual's ability to understand everyday speech. In situations where a direct measure of connected discourse understanding is not possible, it would be beneficial to be able to predict a person's ability to understand connected discourse from other speech and audiometric parameters. The aim of this study was to predict the understanding of Cantonese connected discou…
