Acceleration and weakness in parkinsonian dysarthria.

This report presents some of the underlying neuromuscular mechanisms of dysarthric speech production as they are manifested in selected individuals with parkinsonism. Earlier explanations of parkinsonian dysarthria emphasized that the balanced hypertonus of rigidity formed the basis of reduced range of movements in speech. The present data reveal two problems in the neuromuscular control signals that can result in a reduced range of speech movements in the absence of rigidity. These neuromuscular problems are described as acceleration and weakness. The implication of these findings for the evaluation and treatment of parkinsonian dysarthria is discussed.

Cineradiographic assessment of articulatory mobility in the dysarthrias.

This paper describes cineradiographic techniques for the assessment of articulatory mobility in dysarthric subjects. Sample data for the mobility ranges of articulatory points on the tongue, lower lip, and jaw are presented for four normal speakers and four dysarthric speakers. In addition, fleshpoint displacements during the articulatory movements of the dysarthric subjects are used to illustrate abnormalities in the range, rate, and direction of speech movements. Discussion of the point-parameterized cineradiographic data emphasizes possibilities for the clinical evaluation of dysarthric impairments.

Laryngeal aerodynamics associated with selected voice disorders.

Measures of estimated subglottal air pressure and laryngeal air flow during speech production are compared for adults with normal laryngeal function and those with laryngeal abnormalities. The most traditional measure, air flow during sustained vowel production, is not a strong predictor of laryngeal function during speech production. Subglottal air pressure and laryngeal air flow offer insight into voice disorders and provide directions for therapy as well as a method for the quantitative assessment of treatment outcomes.

Perceptual-physiologic approach to evaluation and treatment of dysphonia.

The value of a perceptual-physiologic approach to both the evaluation and treatment of voice disorders is described and illustrated with an example of a patient with ventricular fold phonation. Objective measures are obtained to facilitate the understanding of the underlying pathophysiology and to document change over time. Evaluation data are recorded and interpreted collectively by a speech-otolaryngology team and may be valuable for medicolegal cases. Finally, the evaluation methods, particularly videolaryngoscopy, may be used for biofeedback purposes to facilitate voice therapy.

Restoration of intelligible speech 13 years post-head injury.

This case study demonstrates the efficacy of treatment of a patient with severe dysarthria long after the accepted period of 'neurological recovery'. A physiological approach to treatment was utilized and resulted in a change from non-verbal communication to functional verbal communication.
