Purpose: Aphasia - loss of comprehension or expression of language - is a devastating functional sequela of stroke. There are as yet no effective methods for rehabilitation of aphasia. An assistive device that allows aphasia patients to communicate and interact at speeds approaching real time is urgently needed., Methods: Behavioral and linguistic studies of aphasia patients show that they retain normal thinking processes and most aspects of language. They lack only phonology: the ability to translate (input) and/or output sounds (or written words) such as "ta-ble" into the image of a four-legged object with a top at which one works or eats., Results: We have made a phonology-free communication mobile app that may be useful for patients with aphasia and other communication disorders. Particular innovations of our app include calling Google Images as a "subroutine" to allow a near-infinite number of choices (e.g. food or clothing items) for patients without having to make countless images, and by the use of animation for words, phrases or concepts that cannot be represented by a single image. We have tested our app successfully in one patient., Conclusions: The app may be of great benefit to patients with aphasia and other communication disorders. Implications for Rehabilitation We have made a phonology-free mobile communication app. This app may facilitate communication for patients with aphasia and other communication disorders.
