A Visual Interactive Narrative Intervention (VINI) for aphasia education: Can digital applications administer augmented input to educate stroke survivors with aphasia?

Abstract

ObjectivePersons with aphasia (PWA) face additional barriers to proper healthcare due to inadequate patient education by health professionals unequipped to use augmentative and alternative communication (AAC). The current study examines a digital application that evokes and sustains health information processing through AAC specifically aimed at increasing comprehension with augmented input (AI). MethodsA digital application designed to educate PWA about their health condition was compared to a video-recorded doctor providing oral-only education. Sixteen PWA received both education interventions in a crossover manner. Health information processing was assessed through heart rate (HR) and skin conductance levels (SCL), which were collected continually during each administration of education interventions. ResultsPWA demonstrated greater cognitive processing of health information via HR and SCL indices during the digital application compared to the typical oral-only education intervention. The oral-only intervention led PWA to disengage with health information. ConclusionBy combining visuographic materials and adapted language into a customizable narrative structure, digital applications can utilize AI to educate PWA about basic health information (i.e., diagnosis and prognosis). Practice ImplicationsThe current study’s AAC requires minimal training and can be used as an aided support in conjunction with other techniques that increase PWA’s access to health information.
