<div>This systematic review and meta-analysis investigates the effects of computerized cognitive training on working memory for post-stroke individuals. Comparators included cognitive rehabilitation, waiting control, or other restorative intervention. This study also investigated the effects of transcranial direct current stimulation (tDCS). Since no studies on tDCS were included in the meta-analysis, findings regarding this intervention were not included in this summary.</div>

<div>Meta-analysis showed the following outcomes for computerized cognitive training compared to controls:</div>
<div>
<ul>
<li>no significant improvement in short-term recall or visuospatial span;</li>
<li>significantly improved working memory (SMD = 0.39); and</li>
<li>no significant moderating effects of age, duration of intervention in minutes, or number of sessions.</li>
</ul>
<div>Limitations to this review included high heterogeneity of the included studies in terms of study design, interventions, outcomes measured, and participant characteristics.</div>
