 A growing neurorehabilitation literature suggests that intense treatment may be desired to maximize the effects of therapy following neurologic injury. This investigation is designed to facilitate the development of efficacious, clinically applicable treatment for acquired apraxia of speech by examining the effects of intensity of treatment e.g., 9 hours per week vs. 3 hours per week, while holding total number of sessions constant with a group of speakers who have chronic apraxia of speech and aphasia.
