Occupational Therapy -> Augmentative and Alternative Communication

Augmentative and Alternative Communication

AAC is an alternative way for an individual to communicate when there are difficulties with speech or writing. Occupational therapists (OTs) focus on assisting an individual communicate his or her wants and needs. OTs often collaborate with a speech and language pathologist to find effective AAC methods. An OT may assist in assessing an individual’s visual, perceptual, motor and cognitive skills in order to increase participation and independence with the AAC method.

Skilled interventions

  • AAC Voice Output Button Training

    AAC Voice Output Button Training aims to empower individuals with speech or language impairments by teaching them how to use voice output communication devices. These devices are crucial for facilitating communication in individuals who have difficulty with verbal expression due to conditions such as autism, cerebral palsy, or aphasia.
    The training involves several key components:
    • Device Familiarization: Introducing the individual to the AAC device, explaining its functions, and demonstrating how to activate the voice output button.
    • Button Activation Practice: Engaging in repetitive practice to develop the motor skills required to press the button accurately and consistently.
    • Symbol and Message Association: Teaching the individual to associate symbols or pictures on the device with corresponding messages or phrases, enhancing their ability to communicate specific needs or thoughts.
    • Contextual Use: Practicing the use of the AAC device in various real-life scenarios to promote generalization of skills. This includes using the device during meals, play, or social interactions to express choices, needs, or emotions.
    • Feedback and Reinforcement: Providing immediate feedback and positive reinforcement to encourage correct use and build confidence in using the device.
    Occupational therapists work closely with individuals to tailor the training to their specific communication needs and preferences. The intervention is designed to be engaging and supportive, often incorporating elements of play and interaction to maintain motivation. By enhancing the ability to use AAC devices effectively, this training supports improved communication, greater independence, and enhanced quality of life for individuals with communication challenges.

  • Picture Symbols

    Picture symbols serve as a foundational element in many AAC systems, especially for individuals with cognitive impairments, autism, or developmental disabilities. These visual representations help bridge the communication gap by providing a clear, understandable method for expressing needs, thoughts, and emotions.

    The intervention process involves selecting appropriate symbols that resonate with the user's environment and daily experiences. Symbols can range from generic icons to personalized images that reflect the user's personal life and preferences. The layout of these symbols on communication boards or electronic devices is tailored to the user’s physical abilities and cognitive skills.

    Therapists train users to recognize and select these symbols to form sentences or express ideas. This training extends to caregivers and educators, who are taught how to interpret the selections and encourage ongoing communication. The ultimate goal is to enhance the user’s autonomy and social interaction by enabling them to initiate communication and respond to others in their environment.

  • Speech-Generating Device (SGD)

    SGDs play a pivotal role in enhancing communication for individuals with conditions such as cerebral palsy, autism spectrum disorder, and post-stroke aphasia. These devices are tailored to the user’s specific needs, featuring customizable vocabulary and access methods that can be operated via touch, eye gaze, or switch scanning techniques.

    The intervention process begins with an assessment by a multidisciplinary team, typically including occupational therapists, speech-language pathologists, and sometimes neurologists or physiatrists. Based on the assessment, a suitable SGD is selected and customized with vocabulary and functions that align with the user’s daily communication needs and cognitive abilities.

    Training with an SGD involves teaching the individual how to navigate the interface, select items to generate speech, and integrate the device use into daily activities. The goal is to promote autonomy and enhance social interaction. Family members and caregivers are also trained to support the user, ensuring effective communication across all settings.

    Author: Case-Smith, Jane.  - Three themes were identified: "Finding the key" described a procedural reasoning process in which the participants searched for the underlying reasons for each student's behaviors and performance. "The whole child" emphasized the importance of the student's psychosocial core and described the therapist's use of interactive and conditional reasoning to form supportive relationships with their students. Because each participant valued the student's vision of a new self, she was able to help the student achieve new social roles and improved self-esteem. "Whose success is this?" told of the importance of a cohesive team, which included the parents, to the child's success. The child's achievement of important life goals and success as a student seemed to be the result of a team effort to which occupational therapy contributed.
