This systematic review investigates the effect of verb tense inflection training (i.e., computerized visual communication protocol [C-VIC], thematic role training, ACTION treatment, morphophonology treatment, morphosemantic treatment, and modified constraint induced language therapy [CILT] with morphosyntactic constraints) on tense marking, sentence production, and narrative speech for people with agrammatic aphasia.

<div>The following findings were reported for expressive verb-focuses language interventions in adults with agrammatic aphasia:</div>
<div>
<ul>
<li>Computerized visual communication protocol improved verb inflection for trained items which generalized to the sentence level (generalization to narrative speech was not measured); however, generalization of untrained items was mixed.</li>
<li>ACTION treatment had positive effects on tense marking for both trained and untrained items that generalized to sentence production and narrative speech.</li>
<li>Thematic role training showed improvements in verb tense inflection, but included studies did not assess generalization.</li>
<li>CILT treatment with morphosyntactic constraints improved verb inflection but did not generalize to the sentence or narrative speech level.</li>
<li>Morphosemantic treatment yielded positive outcomes for verb tense inflection, sentence production, and narrative speech for both trained and untrained items.</li>
<li>Morphophonology treatment did not show any positive results for verb tense inflection or generalization.</li>
</ul>
