Motor speech disorders (dysarthria) comprise a group of speech disorders resulting from disturbances in muscular control due to impairment of any of the basic motor processes involved in the execution of speech. During the period of 10 years from 1980 to 1989, the incidence of motor speech disorders in the author's clinic was 16.7% (248 out of total of 1, 485 patients with language and speech disorders). In clinical practice, it is quite important not to overlook progressive neurological diseases, such as bulbar palsy . In this paper, points of clinical examination are described together with perceptual and acoustic methods of evaluation of pathological speech. The importance of total rehabilitation of dysarthric subjects is emphasized, and the use of different types of speech aids is recommended.
