Efficacy of oral reading in the treatment of two patients with chronic Broca's aphasia.

Two patients with chronic Broca's aphasia participated in an oral reading treatment program. A multiple baseline design across responses was used. Materials consisted of 90 sentences randomly divided into three groups. Baseline performance was established; then each group of sentences was trained sequentially for 10 sessions. At the end of each session, oral reading performance was probed. For both patients, results indicated increases in accuracy of oral reading of treated materials, with maintenance of performance following termination of treatment. However, generalization to oral reading of untreated material as well as generalization to other oral language tasks were evident only for the aphasic patient with a severe apraxia of speech.
