Use of Augmentative/Alternative Communication in Patients with Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is often associated with oropharyngeal weakness, which impairs oral communication. Augmentative/alternative communication (AAC) is sometimes used to compensate for this deficit. We reviewed our experience in providing AAC services to individuals with ALS in order to identify characteristics that might predict successful outcomes. Medical records of twenty-four patients with ALS who completed AAC evaluations were reviewed. A difference was noted between users and nonusers of AAC devices when combined scales measuring oral communication and total functional abilities were utilized. Highly motivated patients with specific communication goals are most likely to benefit from AAC services. Prospective studies, including technology acceptance, are needed to identify the ALS patients who will successfully use AAC systems.
