title: Application of the ICF in reduced speech intelligibility in dysarthria.
abstract: Regardless of the underlying neuromotor impairment, an almost universal consequence of dysarthria is a reduction in speech intelligibility. The purpose of this article is to examine critically and to discuss issues related directly to speech intelligibility in speakers with dysarthria. Reduced speech intelligibility resulting from dysarthria is examined using the World Health Organization's International Classification of Functioning, Disability and Health (ICF) conceptual framework. We propose that the ICF conceptual framework facilitates an awareness of the multidimensional nature of disablement. Furthermore, the ICF facilitates a broad understanding of the complex nature of dysarthria, ranging from the neuroanatomical and physiological substrates contributing to reduced speech intelligibility, to the effects of this type of communication disorder on an individual's functioning in society and beyond. Finally, a case example is presented that describes how the ICF can be applied to an individual with dysarthria and reduced speech intelligibility.
