AAC Performance Data for an Individual With Amyotrophic Lateral Sclerosis
By Cook, Stephanie; Hill, Katya; RESNA 26th International Annual Conference 2003,Publication Date: 2003
Case study presents performance data that may be utilized in making clinical decisions regarding alternative access to an augmentative and alternative communication (AAC) system for people with amyotrophic lateral sclerosis (ALS). People with ALS may have rapidly changing needs regarding the deterioration of physical access to an AAC system. Methods and tools are available to measure selection and communication rates to compare access methods. A 70-year-old man with ALS participated in the study. He had no residual speech or writing ability, and was using a low-tech alphabet board for spelling. The participant’s performance data were collected while he used a Pathfinder synthesized speech hybrid AAC system. Responses while utilizing the Pathfinder system were loaded into a computer for analysis using the Performance Report Tool. Quantitative results are displayed in table format. Due to the rapid decline of the participant’s condition, frequent modifications were necessary to further customize the device to his progressing needs. The participant’s strengths and weaknesses were accurately assessed through the analysis system, allowing for modifications as needed. The authors conclude that with the use of evidence-based practice to customize AAC devices for people with ALS, the population’s potential for effective, accurate communication can greatly increase.
