Assistive Communication Devices in Rett Syndrome: A Case Report and Narrative Review

Abstract

Rett syndrome (RTT) is a severe neurodevelopmental disorder primarily affecting females, characterized by developmental regression and significant communication impairments. Despite the critical role of communication in maintaining quality of life, the long-term efficacy and optimal utilization of augmentative and assistive communication (AAC) devices in RTT remain underexplored. This study evaluates the impact of AAC devices on communication outcomes and quality of life in individuals with RTT through a case report and narrative review. We conducted a comprehensive literature review and thematic analysis categorizing technologies into communication aids, mobility aids, educational tools, and daily living aids, assessing their effectiveness and challenges. The results show that AAC technologies, including eye-tracking devices, speech-generating devices, and adapted computers, enhance communication, cognitive development, and quality of life for individuals with RTT. The case report of Patient E, utilizing the Tobii Dynavox device, highlights the transformative impact of AAC devices despite challenges in device complexity and therapist training. AAC devices are indispensable for supporting individuals with RTT, though challenges persist related to accessibility, device complexity, and therapist training. Future research should focus on longitudinal studies to assess the sustained impact of AAC technologies and explore family-centered approaches to AAC integration.
