8 studies
<div>Meta-analysis resulted in inconclusive findings, with no indication of superiority for any treatment intensity for language interventions in adults with chronic aphasia. Specific findings included:</div>
<div>
<ul>
<li>There was limited evidence to suggest that lower intensity (i.e., less than 3 hours of intervention per week) aphasia treatments for people with chronic aphasia resulted in marginally more favorable outcomes immediately after treatment. However, these differences were not statistically significant . </li>
<li>No significant difference in effect size was noted at one month follow-up.</li>
<li>Treatment intensity demonstrated no significant effect on secondary outcomes such as quality of life.</li>
</ul>
<div>Further research is indicated due to an overall paucity of research and small sample sizes and notable risk of bias in included studies.</div>
