Assessing Communication Deficits for Augmentative and Assistive Communication (AAC)
The SLP is responsible for identifying cognitive and language strengths and weaknesses to determine how they will affect AAC selection and use (DeRuyter & Becker, 1988).  Many standardized assessments have been developed to measure speech and language abilities of individuals with neurological impairments (e.g., stroke, TBI).  These tools can be used to gather information of functional speech, language, and cognitive-communication abilities for AAC purposes (Fletcher, 1997).  Also, non-standardized evaluations are used to assess speech, language, and cognitive-communication abilities (Tanchak & Sawyer, 1995).

Communication disorders dramatically change over course of recovery.  It is important to look at individual needs to address natural speech recovery.
 

Implementing Augmentative and Alternative Communication
The goal of implementing an augmentative and alternative communication (AAC) system is to provide communication assistance so that the TBI survivor is able to participate effectively in a rehabilitation program and is able to communicate wants and needs (Beukelman & Mirenda, 1998).  SLPs should provide a series of AAC systems as recovery progresses. 
 
 
Severe Communication Impairments
  • Stimulate consistent responses
  • Require sufficient cognitive recovery to integrate new learning and appreciate an alternative system as means of communication
aTrain family, staff, and frequent communication partners to assume responsibility for communication and accept survivors mode of response
aFacilitate a yes/no response (e.g., eye blink, head turn, chin up, thumb up/down, writing, pointing, universal head shakes)
aSingle switch used to teach cause and effect 
aSingle switch accessing used for communication or environmental control
aCommunication boards, communication books, lap boards, and the like are implemented for selecting limited picture symbols (1-4) for choice making via pointing, scanning, and/or partner reliance
O
Moderate Communication Impairments
  • Provide a means for patient to express basic needs
aCommunication partners shift to communication facilitator by introducing topics, resolving communication breakdowns, and creating motivating communication opportunities
aCompensate for attention and memory impairments (e.g., daily planner, schedule books, memory log)
aAlphabet boards, pictures, word boards, yes/no techniques, eye gaze boards, scanning, etc. utilized to support conversational interaction to fulfill wants and needs and share information
aIncrease number of pictures displayed on communication board
aEnvironmental specific communication boards are used to promote interaction in various environments with contextual support
aWritten choice communication
aSingle switches for call buttons, appliances, etc. for environmental control
aTrain survivor to slow speech rate for greater intelligibility
aKeyguards and hardware for mounting communication aids to desks or wheelchairs to increase accessibility
aGradually increase complexity of communication 
aUse of communication system to supplement poor speech indelibility
aUse of speech output and/or printed output for alternative or augmentative communication
O
Mild Communication Impairments
  • Provide functional ways to interact with various people in various settings
aAugmented writing systems 
aPrepare for long term communication system
aUtilize AAC systems with orthographic symbol, including letters, words, and sentences)
aHigh tech AAC devices
aTopic identification using communication board
aSupplemented speech using an alphabet board
aPortable voice amplification system
aCompensatory strategies for mild dysarthria
aCompensatory strategies for executive functioning impairments (e.g., daily planners, calendars, note taking, eliminate environmental distractions, break down complex tasks)
Beukelman & Mirenda, (1998), pp. 508-514; Davies (1994), pp. 293-298; Jaffe, Mastrilli, Molitor, & Volka, (1985), pp. 174-191

Treatment changes as the patient responds more appropriately to the environment.  Throughout recovery process, utilization of multiple modalities (e.g., gesturing, writing, pictures, drawing) will increase communicative effectiveness.
