This investigation describes a treatment program for an adult patient with apraxia of speech. The program was composed of a series of physiologic (nonspeech) and phonetic (articulatory) tasks that began with oroneuromotor control activities and progressed to consonant-vowel (CV) syllable, word, and sentence drills. All activities were paced by a metronome. Detailed descriptions are provided about the (a) nature of the specific treatment steps,(b) sequence of steps followed, (c) criteria used for progression within and between steps, (d) actual number of trials and time required to reach criteria for each step, and (e) steps that were especially easy or difficult to master. A multiple probe design employed to test program efficacy revealed that (a) all tasks in the treatment program were successfully acquired, (b) control of all treatment behaviors was maintained, and (c) carry-over from treated to nontreated behaviors did not occur. Results confirmed that the program positively affected the patient's performance. Suggestions are offered outlining possible modification of the treatment steps so as to yield similar results with greater clinical efficiency.
