The 2018 biennial Conference on Motor Speech gathered researchers from around the world to discuss the topics of speech motor control and motor speech disorders. This year, ASHA Journals has published two issues that share important findings from this conference: (1) a special issue of the American Journal of Speech-Language Pathology (AJSLP) and (2) a forum published in the Journal of Speech, Language, and Hearing Research (JSLHR).
The AJSLP special issue focuses on clinical science and innovations and includes 13 articles. Three articles focus on the identification and characterization of motor speech disorders in children, including 5-year-old children with cerebral palsy and childhood apraxia of speech, and on the profiling of speech sound disorders. Three additional articles deal with the evaluation and management of motor speech disorders in individuals with Parkinson’s disease and apraxia of speech with aphasia. The remaining articles feature a range of themes.
The forum in JSLHR focuses on basic science and clinical innovation. These articles cover a wide swath of topics involving individuals with Parkinson’s disease or other severe motor disorders, including those who use augmentative and alternative communication (AAC) or a brain–computer interface (BCI).
We would like to thank Special Issue Editor Kristie Spencer and Forum Editor Michael Hammer for their work putting together these articles. Enjoy reading the collections below, or explore the individual articles in the “Explore the Issue” and “Explore the Forum” sections. If you missed it, you can also read highlights of these issues from the 2016 Conference on Motor Speech!
