Augmentative and Alternative Communication (AAC)
What is AAC?
Augmentative and Alternative Communication is an area of clinical practice that attempts to compensate for severe oral expressive communication deficits using "low technology" options such as picture boards or "high technology" options like digital voice output devices. AAC devices may be used for a temporary or permanent deficit.
Who specializes in AAC?
Speech language pathologists specialize in evaluating and treating communication disorders of all levels of severity. For individuals with significant oral language impairments, it is important to select a speech language pathologist who specializes in AAC to gain the maximum benefit from evaluation and treatment sessions.
Who might need an AAC Assessment?
People with physical, sensory and/or cognitive impairments that may affect overall communication abilities
People who anticipate decline in their ability to speak due to progressive neurological disorders
People who are not able to communicate functional needs such as comfort, pain or nutrition
What kinds of conditions typically cause severe communication impairments?
Acquired conditions such as a cerebrovascular accident (CVA or also referred to as "stroke") or traumatic brain injury (TBI)
Progressive neurological conditions such as amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) or Parkinson's disease
Congenital ("since birth") conditions such as cerebral palsy (CP) or genetic syndromes (for example, Down Syndrome)
What could an AAC assessment include?
The evaluating speech-language pathologist gathers information regarding the communication needs of an individual and uses that information to select options for AAC systems. An AAC recommendation is made based on the individual's communication needs and their ability to use specific systems. The evaluation session could include any of the following:
Oral Mechanism Examination
Hearing screening
Articulation proficiency assessment
Language function evaluation
Voice/fluency assessment
Cognitive and behavioral observations
Vision/visual perception screening
Motor control evaluation
Determination of seating and positioning options
Assessment of communication needs
Evaluation with specific AAC systems
Determination of psychosocial factors and motivation level
