Introduction

Friedreich's Ataxia (FA) is a rare genetic disorder affecting approximately 1 in 50,000 individuals worldwide. It's caused by mutations in the FXN gene, leading to a deficiency in the frataxin protein, which results in cellular damage, particularly in nerve and muscle cells. Symptoms include progressive gait and limb ataxia, muscle weakness, cardiac issues, and diabetes mellitus. Diagnosis involves clinical examination, genetic testing, and additional tests. Most individuals with FA will require assistive technology due to progressive physical and neurological impairments. Management strategies include symptom management, multidisciplinary approach, speech therapy, individualized education plans, and occupational therapy. Medical management, behavioral and psychological support, early intervention programs, and educational strategies are also crucial. Ongoing studies into the genetic mechanisms of FA and potential gene therapies are future research directions.

Assistive Technology and Communication Devices

Assistive technology plays a crucial role in enhancing communication, independence, and quality of life for individuals with FA. Given the speech and language difficulties and motor impairments associated with FA, many individuals may benefit from assistive technology.

Speech Generating Devices (SGDs)

Individuals with FA often have significant speech and language impairments. Augmentative and Alternative Communication (AAC) is crucial for enabling them to express their needs, thoughts, and feelings.

Importance of Symbols for Individuals with FA

Symbols are an essential component of AAC systems for individuals with FA due to several factors:

• Cognitive and Linguistic Challenges: Most individuals with FA have significant cognitive impairments and limited or no verbal language skills. Symbols provide a more concrete and accessible way to represent language concepts compared to abstract text.
• Visual Processing Strengths: Despite the presence of visual impairments in some individuals with FA, many demonstrate relative strengths in visual processing compared to auditory processing. Visual symbols capitalize on these strengths to support communication.
• Developmental Appropriateness: Symbols, particularly those that closely resemble real objects or actions, align with the developmental level of most individuals with FA. They provide a more natural starting point for communication development compared to text.
• Learnability and Retention: Well-designed symbols are easier to learn and remember than abstract text for individuals with significant cognitive and memory impairments. Consistent use of symbols across environments and communication partners can further enhance learnability.
• Engagement and Motivation: Colorful, engaging symbols can capture attention and motivate individuals with FA to interact with their AAC system. Personalized symbols reflecting an individual's interests and preferences can be particularly effective.

Assessment and Selection of Symbol Sets

A comprehensive AAC assessment is essential to determine the most appropriate symbol set for an individual with FA. Key considerations include:

• Symbolic Understanding: Assess the individual's ability to understand and use various types of symbols, from simple, concrete representations to more abstract concepts. Some standardized assessments, such as the Test of Aided-Communication Symbol Performance (TASP) or the Symbolic Communication Assessment Scale (SCAS), can help evaluate symbolic understanding.
• Visual Skills: Consider the individual's visual acuity, visual field, and visual perceptual skills when selecting symbols. Individuals with significant visual impairments may require larger, higher-contrast symbols or even tactile symbols.
• Motor Skills: Evaluate the individual's ability to accurately select symbols given their motor abilities. Symbols may need to be spaced farther apart or presented in a linear layout to accommodate motor challenges.
• Customization: Be prepared to customize symbol sets to reflect an individual's specific needs, interests, and environment. Personal photos, for example, can be highly meaningful and motivating.

Some commonly used symbol sets in AAC include:

• Picture Communication Symbols (PCS): A widely used set of clear, simple line drawings representing a wide range of vocabulary.
• SymbolStix: A set of colorful, stylized symbols designed for clarity and consistency across vocabulary categories.
• Photographs: Real-life photos can be highly relevant and recognizable, especially for concrete, personal vocabulary items.
• Tactile Symbols: Three-dimensional symbols that can be felt and explored, useful for individuals with significant visual impairments.

Ultimately, the selection of a symbol set should be driven by an individual's unique profile and preferences. Many individuals with FA may benefit from a combination of symbol types within their AAC system.

Access Methods

The choice of access method is crucial for successful AAC use and depends on an individual's motor, cognitive, and sensory abilities. For individuals with FA, common access methods include:

Direct Selection

Individuals with sufficient motor control may be able to directly select symbols on a screen or communication board using their finger, hand, or a pointer. Key considerations for direct selection with FA include:

• Accuracy: Assess an individual's ability to isolate a finger or accurately use a pointer to select symbols. Larger symbols and increased spacing between symbols may be necessary to accommodate motor challenges.
• Fatigue: Direct selection can be physically taxing, especially for individuals with significant motor impairments. Frequent breaks and careful positioning are essential.
• Interference from Involuntary Movements: Involuntary movements, such as tremors or spasms, can make direct selection challenging. Stabilizing techniques, such as using a keyguard or mounting the device, can help.

Eye Gaze

For individuals with significant motor impairments but good ocular control, eye gaze systems can provide an efficient access method. Key considerations for eye gaze with FA include:

• Calibration: Accurate calibration is essential for successful eye gaze use. This can be challenging for individuals with nystagmus, strabismus, or significant head movements. Multiple calibration attempts or customized calibration settings may be necessary.
• Visual Skills: Assess an individual's visual acuity, visual field, and oculomotor control to determine the appropriateness of eye gaze. Larger symbols, increased spacing, and high-contrast displays may be necessary to accommodate visual impairments.
• Positioning: Proper positioning of both the individual and the eye gaze device is crucial for comfort and accuracy. A stable head position and minimized glare on the screen are important considerations.

Switch Scanning

For individuals with severe motor impairments who cannot reliably point or use eye gaze, scanning allows them to select symbols using a switch or switches. Key considerations for scanning with FA include:

• Cognitive Demands: Scanning requires significant cognitive skills, including attention, timing, and sequencing. Careful assessment of an individual's cognitive profile is essential to determine the appropriateness of scanning.
• Auditory and Visual Prompts: Scanning relies on auditory and/or visual prompts to guide an

Switch Scanning

For individuals with severe motor impairments who cannot reliably point or use eye gaze, scanning allows them to select symbols using a switch or switches. Key considerations for scanning with FA include:

• Cognitive Demands: Scanning requires significant cognitive skills, including attention, timing, and sequencing. Careful assessment of an individual's cognitive profile is essential to determine the appropriateness of scanning.
• Auditory and Visual Prompts: Scanning relies on auditory and/or visual prompts to guide an individual through the selection process. Ensure that the prompts are appropriate given an individual's sensory abilities and preferences.
• Customization: Scanning patterns, speed, and switch placement should be customized to an individual's unique needs and abilities. Ongoing adjustments may be necessary as skills develop or change over time.
• Partner-Assisted Scanning: For individuals with the most severe motor and cognitive impairments, partner-assisted scanning may be the most appropriate access method. In this approach, a communication partner presents choices auditorily or visually, and the individual indicates a choice through a predetermined signal, such as an eye blink or vocalization.

Ultimately, the selection of an access method should be driven by a comprehensive assessment of an individual's strengths, needs, and preferences. Many individuals with FA may benefit from a combination of access methods depending on the context and their changing abilities over time.

Literacy Considerations

While many individuals with FA may not develop traditional literacy skills, it is essential to provide opportunities for literacy development within their AAC systems:

• Exposure to Print: Consistently pairing symbols with printed words can help build print awareness and recognition over time. Even if an individual does not develop independent reading skills, exposure to print can support language development and provide a foundation for future literacy learning.
• Sight Words: Some individuals with FA may develop sight word recognition, even if they do not develop full reading skills. Incorporating personally meaningful sight words into an AAC system can enhance communication efficiency and support participation in literacy-based activities.
• Phonological Awareness: Incorporating activities targeting phonological awareness, such as rhyming or initial sound identification, can lay the groundwork for literacy development. These activities can be adapted to an individual's cognitive and linguistic level and integrated into AAC use.
• Shared Reading: Regularly engaging in shared reading activities, using adapted books with symbol support, can build language skills and foster a love of literacy. Interactive reading techniques, such as pausing for participation or asking questions, can further enhance engagement and comprehension.

Ultimately, literacy goals for individuals with FA should be individualized based on their unique profiles and learning trajectories. AAC systems should be designed to grow with an individual's developing skills and provide ongoing opportunities for literacy learning.

Customization and Implementation
