ALS Speech Therapy: Treatments and Communication Strategies

Progressive Communication Impairment in ALS

ALS (amyotrophic lateral sclerosis) causes bulbar motor neuron degeneration → dysarthria, hypophonia, eventual anarthria. Cognitive-linguistic skills often preserved.

Multidisciplinary Interventions

1. Speech-Language Pathology (SLP)

• Compensatory strategies: slow rate, over-articulation, phrasing, breath support.
• Voice banking (record phrases for future speech-generating device).
• Message banking (record personally meaningful messages).

2. Augmentative and Alternative Communication (AAC)

• Low-tech: Alphabet boards, partner-assisted scanning, eye-gaze frames.
• High-tech: Speech-generating devices (SGDs) – tablet-based (Predictable, Proloquo4Text), dedicated devices (Tobii Dynavox, PRC-Saltillo).
• Access methods: Touch, switch scanning, head tracking, eye-gaze (critical when limb function lost).

3. Assistive Technology

• Text-to-speech apps, voice amplifiers, environmental control units (ECUs).

4. Swallowing Therapy

• Dysphagia management: diet modification, compensatory maneuvers (chin tuck), NMES, expiratory muscle strength training.
• Prevent aspiration pneumonia.

5. Respiratory Support Integration

• NIV (BiPAP) → interface with AAC (e.g., switch access during mask breaks).
• Tracheostomy → speaking valve (Passy-Muir) for voicing; AAC adaptation.

6. Caregiver Training

• Partner-assisted communication techniques.
• Device setup, troubleshooting, modeling.

7. Emerging Research

• Brain-computer interfaces (BCI) for direct neural communication.
• AI-driven predictive language models for faster AAC output.

Early SLP referral (at diagnosis) maximizes communication autonomy throughout disease course.
