The efficacy of language rehabilitation therapy: a meta-analytic review of traumatic brain injury and stroke cognitive rehabilitation literature

Abstract

This meta-analysis evaluated 10 studies of language rehabilitation and recovery that were conducted after a patient endured a traumatic brain injury or stroke. The primary purpose of this meta-analysis was to determine the overall effect size across these studies and to assess the significance of this aggregate effect size. Results indicated a significant effect size in the control conditions (r = .3, p < .05) in which patients received no rehabilitative therapy. A significant effect size was also present in the intervention conditions (r = .4, p < .05). Results showed that language rehabilitation therapies are effective therapeutic interventions, with significant improvements being shown above and beyond what could attributed to the passage of time.
