Motor speech disorders

This special issue of Folia Phoniatrica et Logopaedica contains contributions representing a diverse set of perspectives on current theoretical and clinical aspects of child and adult motor speech disorders. Topics covered include dysarthria associated with Friedreich’s ataxia, Parkinson’s disease and apraxia of speech. Theoretical considerations concerning the diagnostic classification of dysarthria and the use of a computational neural model of speech motor symptoms are discussed. Further articles highlight the importance of dysarthria research in languages other than English to test theoretical models of dysarthric speech. For speech pathologists, students and all health professionals involved in this field, this issue provides a valuable update of current international research into the assessment, diagnosis and treatment of motor speech disorders.
