The article reviews common misconceptions about oral pharyngeal structure and function and suggests the need for more adequate training in order to make more reliable decisions about the adequacy of the speech mechanism. (CL)

This investigation compared five parameters of phonatory function in an examination of the use of acoustic measures in differential diagnosis in 39 subjects in 3 neuropathological groups (Parkinson, Huntington, cerebellar ataxia) and a normal control group. Results indicated higher variability in perturbation in all the neuropathological groups.…

Presented is a study of a 20-year-old girl with mild, breathy dysphonia, previously diagnosed as psychogenic. In actuality, her voice change was a sign of early myasthenia gravis. It is pointed out that voice changes can be a first and only sign of early neurologic disease. (Author/KW)

This tutorial in nonlinear phonology introduces the basic concepts and assumptions of this new theoretical approach and then demonstrates clinical applications of the theory for assessment and intervention. Data from a child with a severe phonological disorder are used to illustrate aspects of nonlinear theory. (Author/DB)

The perceptual assessment of voice disorders by speech pathologists and interjudge reliability were investigated through screening of 160 children (4-14 years old). Results demonstrated poor interjudge agreement between the listeners and indicate a need for more objective measures in the identification of voice disorders. (Author/SEW)

This article reviews 19 common myths in voice therapy. Issues examined include developmental factors, iatrogenic voice disorders, breathing habits, optimum pitch, palate training, and etiology based on perceptual cues. More referral, assessment, and decision making are needed, as well as development of standards for the management of voice…

Part 1 of this paper recommends procedures and standards for the acoustic analysis of voice in individuals with dysarthria. In Part 2, acoustic data are reviewed for dysarthria associated with Parkinson disease (PD), cerebellar disease, amytrophic lateral sclerosis, traumatic brain injury, unilateral hemispheric stroke, and essential tremor.…

Children with laryngeal pathologies or alterations in laryngeal structure and/or function often present with complex medical profiles. This article presents case studies for the speech-language pathologist that provide information regarding management decisions and specific treatment options. (Author/DB)

Resonance disorders can have a variety of causes but the appropriate evaluation includes a speech pathology evaluation and may require a videofluoroscopic speech study or nasopharyngoscopy assessment. Treatment may include surgery or the use of prosthetic devices, and usually speech therapy. An interdisciplinary approach is best. (Author/DB)
