We used a well-defined therapy protocol [i.e., Computerized Visual Communication System (C-VIC) training] to target production of tense morphology and an assessment specifically designed to measure improvements in the targeted behavior. We first trained Subject #1, a 65-year-old man with a severe nonfluent aphasia, to produce simple subject-verb-object sentences, then tense-marked sentences. Remarkable improvement was shown and was maintained five months after training was terminated. Sixteen months later, he maintained only the ability to produce trained root verb forms. A second training was initiated to examine the parameters of training that affect maintenance. Maintenance was demonstrated up to a year after termination of treatment. We attribute Subject #1's maintained performance to his continued involvement in general C-VIC sentence level therapy following tense training.<\/jats:p>","DOI":"10.1177\/154596830001400203","type":"journal-article","created":{"date-parts":[[2015,11,25]],"date-time":"2015-11-25T06:40:22Z","timestamp":1448433622000},"page":"105-118","source":"Crossref","is-referenced-by-count":10,"title":["Maintenance of Oral Production in Agrammatic Aphasia: Verb Tense Morphology Training"],"prefix":"10.1177","volume":"14","author":[{"given":"Katharina I.","family":"Boser","sequence":"first","affiliation":[{"name":"From the University of Maryland at Baltimore, School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Weinrich","sequence":"additional","affiliation":[{"name":"From the University of Maryland at Baltimore, School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise","family":"McCall","sequence":"additional","affiliation":[{"name":"From the University of Maryland at Baltimore, School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2000,6,1]]},"reference":[{"key":"bibr1-154596830001400203","volume-title":"National report cards numbers 1\u20138: Adults in health care settings","year":"1996"},{"key":"bibr2-154596830001400203","first-page":"299","volume-title":"Clinical aphasiology","volume":"20","author":"Aten J","year":"1990"},{"key":"bibr3-154596830001400203","first-page":"156","volume-title":"Clinical aphasiology","volume":"13","author":"Collins MJ","year":"1983"},{"key":"bibr4-154596830001400203","first-page":"240","volume-title":"Clinical aphasiology","volume":"10","author":"Holland AL","year":"1980"},{"key":"bibr5-154596830001400203","volume-title":"The Porch index of communicative ability.","author":"Porch B","year":"1967"},{"key":"bibr6-154596830001400203","volume-title":"Communicative abilities in daily living (CADL)","author":"Holland AL","year":"1980"},{"key":"bibr7-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1044\/jshd.4701.93"},{"key":"bibr8-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1044\/jshd.4902.152"},{"key":"bibr9-154596830001400203","first-page":"35","volume-title":"Clinical aphasiology","author":"Thompson C","year":"1981"},{"key":"bibr10-154596830001400203","first-page":"945","volume-title":"Handbook of psycholinguistics","author":"Bock K","year":"1994"},{"key":"bibr11-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1016\/0028-3932(89)90048-1"},{"key":"bibr12-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1016\/0093-934X(89)90075-8"},{"key":"bibr13-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1080\/02687039608248415"},{"key":"bibr14-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1016\/S0166-4115(08)61205-4"},{"key":"bibr15-154596830001400203","volume-title":"Advances in clinical rehabilitation","author":"Mitchum CC","year":"1988"},{"key":"bibr16-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1080\/02643299508252006"},{"key":"bibr17-154596830001400203","first-page":"39","volume-title":"Cognitive approaches in rehabilitation","author":"Howard D","year":"1989"},{"key":"bibr18-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1006\/brln.1996.0009"},{"key":"bibr19-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1006\/brln.1997.1757"},{"key":"bibr20-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1037\/0033-295X.89.6.708"},{"key":"bibr21-154596830001400203","doi-asserted-by":"publisher","DOI":"10.1080\/026432997381637"},{"key":"bibr22-154596830001400203","unstructured":"Weinrich M, Boser K, McCall D.
