Development of yes/no systems in individuals with severe traumatic brain injuries

Abstract

The development of yes/no systems by 82 individuals with severe traumatic brain injuries (TBI) was studied in a rehabilitation setting and through a follow-up survey. The purpose of the study was to investigate the need for augmentative and alternative communication (AAC) for this population, the different types of yes/no systems utilized both in a rehabilitation setting and after discharge, the time frame for developing a yes/no system, and the long-term needs for clinical intervention. Results indicated that individuals with severe brain injuries can successfully use simple AAC systems. The time frame for development of these systems is highly variable and depends to a large extent on cognitive, motor, and medical factors. These individuals need continuous intervention or consultation regarding their communication because of the changing nature of TBI.
