This study shows that augmentative and alternative communication (AAC) devices can improve communication for adults with chronic non-fluent aphasia (NA). Caregiver involvement enhanced the effectiveness of AAC interventions.
Area of Science:
- Neurology
- Speech-Language Pathology
- Assistive Technology
Background:
- Augmentative and alternative communication (AAC) interventions are common for adults with aphasia.
- Specific approaches and strategies used in AAC interventions are not always detailed in studies.
- Chronic non-fluent aphasia (NA) presents significant communication challenges.
Purpose of the Study:
- To examine the communication abilities of individuals with chronic NA using a dynamic display AAC device.
- To assess the effectiveness of a tailored AAC intervention protocol.
- To explore the impact of AAC on linguistic and cognitive functioning.
Main Methods:
- Three adults with chronic non-fluent aphasia participated.
- A dynamic display AAC device (Dialect with Speaking Dynamically Pro) was utilized.
- A treatment protocol adapted from Koul, Corwin, and Hayes (2005) was employed, with spouse as primary caregiver.
Main Results:
- All participants demonstrated improvements in the quality and effectiveness of their communication.
- Two participants showed enhanced linguistic and cognitive functioning post-intervention.
- The tailored AAC approach proved beneficial for communication enhancement.
Conclusions:
- Dynamic display AAC devices can effectively enhance communication in adults with chronic non-fluent aphasia.
- Tailored interventions and caregiver involvement are crucial for successful AAC implementation.
- Further research is warranted on AAC device use in this population.

Barriers to Effective Communication II
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
