Use of AAC to Enhance Social Participation of Adults with Neurological Conditions

David Beukelman


Susan Fager & Laura Ball

2006 AAC-RERC State of Science Conference

  • To review “AAC-State of the Science” for persons with acquired conditions that result in complex communication needs.
    • Amyotrophic lateral sclerosis
    • Brainstem impairment
    • Traumatic brain injury
    • Chronic, severe aphasia
    • Dementia
    • Parkinson disease
    • Multiple sclerosis
    • Myasthenia gravis
    • Huntington disease
als demographics
ALS: Demographics
  • Age of onset--20s to 60s
  • Initial spinal symptoms live 5 times longer than those with initial bulbar symptoms
  • Life expectance is much longer if one opt s for invasive ventilation
  • Artificial nutrition increases life expectancy somewhat, increases quality of life.
ALS: AAC Acceptance & UseNebraska ALS Database (N = 140) (Ball, Beukelman, Pattee & colleagues (2000, 2001, 2002, 2004, 2005, 2006)
  • 95% unable to speak prior to death
  • 96% accept AAC (6% delay; 4% reject), similar for men and women
  • All, who accept, use until within a month or two of death
  • Length of use is remarkably similar for those with initial spinal (23 months) or bulbar symptoms (26 months) (under-estimates because 15% continued to use while ventilated)
  • Communication functions documented (Mathy,Yorkston, & Gutmann, 2000)
als aac referral
ALS: AAC Referral

Delayed referral for AAC assessment remains a primary intervention issue.

  • Current medical interventions reducing percentage and type of persons with complex communication needs (Research Needed).
tbi aac acceptance and use
TBI: AAC Acceptance and Use
  • Most recent review (Fager, et al., 2006)
    • 94% accepted high tech AAC recommendation
    • 81% continued to use after 5 years
    • 87% letter-by-letter spelling
    • 13% symbols, icons, and drawings
    • 6% did not receive AAC device--funding issues
    • 12% discontinued use--AAC facilitator issues
tbi aac acceptance and use14
TBI: AAC Acceptance and Use
  • 100% who used low tech AAC accepted recommendation
  • 63% still using after 3 years
  • 37% discontinued because they regained functional, natural speech
  • All used letter-by-letter spelling, except 1 who used icons and drawings. His was injured as a child before becoming literate.

Speakers (N = 8)

tbi future directions

  • Current acceptance and use higher than reports in the 1987
  • Reduce cognitive load--to reduce reliance on letter-by-letter spelling
  • Supporting facilitator learning
  • Supporting the use of residual speech
brainstem impairment demographics
Brainstem Impairment: Demographics
  • 0 - 25% recover functional speech (depending on study) (Katz, 1992; Culp & Ladtkow, 1992; Soderholm, Meinander, & Alaranta, 2001)
  • 4 Clinical Profiles
    • Motor impairment--but not Locked-in Syndrome
    • LIS, but transitioning to brainstem motor involvement
    • Chronic LIS

Brainstem: AAC Acceptance and Use
  • 3 Published Reports of Groups of Individuals (Katz,, 1992; Culp and Ladkow,1992; Soderholm, Meinander, & Alaranta, 2001)
    • Use both high and low tech AAC
    • Of high tech AAC, approximately half direct selection and half scanning.
    • An undocumented group remains “Locked-in” using eye-gaze and signals (dependent scanning)
lis restoring head movement
LIS: Restoring Head Movement
  • Safe Laser Project (Fager et al, 2006)
    • 6 participants
    • Initially, all communication with eye movements
    • After intervention,
      • 3 developed sufficient head control to access AAC technology
      • 2 continue motor learning intervention
      • 1 discontinued--health and psychological issues
