Post-stroke aphasia rehabilitation using computer-based Arabic software program: a randomized controlled trial

Abstract

Background: Aphasia is considered an acquired communication disorder. Language intervention in aphasia enhances the patient outcomes. Recently, computer programs are developed for the treatment of aphasia. It is an effective and a low-cost therapy choice. The aim of the study was to assess the effectiveness of language therapy using a computer-based Arabic software program for rehabilitation of post-stroke Arabic-speaking aphasic patients in comparison to the conventional language therapy. We conducted a randomized controlled trial with blinded endpoint evaluation. The trial included 50 aphasic patients. They were randomized into either group I or group II to receive 48 therapy sessions using the Arabic software program (group I) or the conventional therapy (group II). The primary outcome was a measure of improvement in language abilities. It was measured using the Arabic version of the Boston Diagnostic Aphasia Examination to detect any significant improvement in the language of both groups in comparison to pre-therapy results. The post-therapy results of both groups were compared to each other to document the effectiveness of the software program. Results: A total of 105 aphasic patients were screened and 50 subjects were randomized to the intervention groups [40 subjects were males, mean age of the patients: 57.04 years± SD 10.88 for group I and 58.80 years ± SD 11.58 for group II]. The therapy results showed a significant improvement from the baseline in both groups. There was no significant difference in the post-therapy results between group I and group II except for some items whereas group I showed more significant improvement. Conclusions: Language therapy using a computer-based Arabic software program was as effective as the conventional therapy in the improvement of language abilities of Arabic-speaking aphasic patients.
