Area of Science:

Augmentative and Alternative Communication (AAC)
Neurology
Speech-Language Pathology

Background:

Individuals with severe speech impairments, such as anarthria or dysarthria, often require augmentative communication devices.
The Canon Communicator is one such device used to aid communication.

Purpose of the Study:

To document the successful use of the Canon Communicator by individuals with neurological disorders.
To identify factors influencing the adoption and continued use of this device.

Main Methods:

A questionnaire was administered to speech-language pathologists (SLPs) serving 13 subjects who used the Canon Communicator.
Subjects ranged in age from 17 to 64 years and had used the device for 2 to 24 months.
Subjects had neurological disorders (cerebral palsy, CVA, closed head injury, ALS) but no aphasia.

Main Results:

The Canon Communicator was successfully used by 11 out of 13 subjects.
The decision to recommend the device was faster for older adults.
Despite using multiple communication systems, users preferred the Canon Communicator for frequent use.
No device malfunctions were reported, except for the power supply.

Conclusions:

The Canon Communicator is an effective augmentative communication device for individuals with severe dysarthria or anarthria due to neurological conditions.
The device demonstrates high user satisfaction and continued reliance, particularly among older adults.
Further research could explore specific features contributing to its success and long-term efficacy.
