Parkinson's disease and aided AAC: some evidence from practice

Area of Science:

• Neurology
• Speech-Language Pathology
• Assistive Technology

Background:

• Limited research exists on the effectiveness of aided augmentative and alternative communication (AAC) for individuals with Parkinson's disease (PD).
• Clinical observations suggest distinct training requirements for PD patients using AAC compared to other adult groups.
• A need for evidence-based practice and efficacy research in AAC for PD is apparent.

Purpose of the Study:

• To explore speech and language therapists' experiences and attitudes regarding aided AAC use in individuals with PD.
• To identify factors influencing the introduction, implementation, and successful use of AAC devices by PD patients.
• To lay the groundwork for future efficacy research and improved clinical practice.

Main Methods:

• A preliminary study involving interviews with thirty speech and language therapists.
• Questionnaires focused on therapists' experiences with low- and high-tech AAC devices for PD clients.
• Exploration of disease-specific and general factors impacting AAC use in PD.

Main Results:

• Therapists reported various factors influencing AAC adoption in PD patients.
• Identified factors included both PD-specific challenges (e.g., motor impairments) and general considerations (e.g., caregiver support).
• These factors are crucial for successful AAC implementation and user outcomes.

Conclusions:

• The study highlights the importance of understanding specific patient needs and contextual factors for effective AAC intervention in PD.
• Findings provide a basis for future research into AAC efficacy and clinical guidelines for PD.
• Involving individuals with PD and their caregivers in practice development is recommended for better outcomes.
