This paper considers a range of available designs and describes in detail one study of therapy for an aphasic patient, using a modified multiple\u2010baseline approach. Two targets were chosen for the patient: reducing dyspraxic errors in reading aloud and increasing the use of a sentence\u2010initial grammatical subject in speech. The results of the study appear to show differential improvement on the two targets. These findings are discussed with reference to their implications for future therapy. Whereas the experimental demands of some designs might clash with therapeutic priorities, the modified multiple\u2010baseline approach is sufficiently flexible for clinical use, while, it is argued, adequately demonstrating therapeutic effect. Although initially time\u2010consuming, the information provided by regular measurement should make therapy a more efficient process and it is suggested that such studies can and ought to be incorporated into the clinical routine.<\/jats:p>","DOI":"10.3109\/13682828609018543","type":"journal-article","created":{"date-parts":[[2007,11,18]],"date-time":"2007-11-18T01:19:04Z","timestamp":1195348744000},"page":"47-62","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Measuring progress in aphasia therapy: A multiple baseline study"],"prefix":"10.1111","volume":"21","author":[{"given":"Anne","family":"Hesketh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,3,24]]},"reference":[{"key":"e_1_2_1_2_1","unstructured":"Bishop D.
