Feasibility of an abstract verb naming treatment for aphasia

ABSTRACTPurpose Verb production impairments in aphasia have important implications for sentence production and communication in general. Verbs with low concreteness may be especially important for certain functional uses, and yet limited data regarding their response to treatment are available. This study was designed to examine a novel behavioral treatment approach to improve low concreteness verb naming in persons with aphasia.Method Three persons with nonfluent aphasia participated in a single-subject experimental design research study examining the feasibility of the novel treatment. The treatment was based on approaches that target the verb as the central node of meaning during sentence construction. The primary outcome measure was a sentence completion probe. Effects on untreated stimuli and on general language and naming assessments were also examined.Results Results indicated some limited changes associated with the treatment for two of the participants. Treatment performance data suggested possible improvements in verb processing that were not reflected in the primary outcome measure. Modest decreases in aphasia severity were noted for two of the participants.Conclusions The findings provide further support for targeting verbal production of verbs with low concreteness in aphasia. Several lessons learned may benefit future researchers examining areas related to the topic.KEYWORDS: Aphasiatreatmentabstractconcretenessverbs AcknowledgementSpecial thanks to Lisa Johnson and Heather Bailey for their assistance with this project.

Vary these between sessions as much as is reasonable, depending on the verb’s possibilities and the patient’s preferences.Additional informationFundingThis research was supported by SPiRE Award RX-RX001356-01 and VA RR&D Research Career Scientist Award IK6RX002706, both awarded to Julie Wambaugh.
