This systematic review investigates the effects of treatments for sentence production deficits (e.g., those targeting verbs, sentence structures, or morphology) on gains on trained items, generalization to untreated items, maintenance of the gains, and transfer for individuals with chronic aphasia.

The following findings were noted for the impact of various sentence production treatments for individuals with chronic aphasia:<br />
<ul>
<li><span style="color: #333333;">Sentence production treatments led to improvement on trained items for 80/84 participants; however, results are subject to publication bias. </span></li>
<li><span style="color: #333333;">Most participants (72/84) showed generalization to untrained items, and this was true of treatment of underlying forms (TUF), mapping therapies (MT), computerized visual communication (C-VIC), and verb network strengthening treatment (VneST). </span></li>
<li><span style="color: #333333;">Inter-modality generalization was noted to comprehension (16/25) following sentence production treatments and to written language (6/7) following verbal, TUF treatments.</span></li>
<li><span style="color: #333333;">Across-level generalization to narratives was also seen for most participants in whom it was measured (43/59). </span></li>
<li><span style="color: #333333;">A limited number of studies measured generalization to ecological context such as conversation (3/12). </span></li>
<li><span style="color: #333333;">Maintenance of gains was seen for most participants (42/49); however, the interval measured was typically short (2-6 weeks post-treatment).</span></li>
</ul>
