Speech therapy plan for spinocerebellar ataxia (SCA)

1. Initial assessment and baseline measures

• SCA subtype and disease stage, neurological and respiratory history.
• Main communication situations: phone/video calls, work, group conversation, fatigue, unfamiliar listeners.
• Patient and family goals, for example: “be understood by my grandchildren” or “make phone calls independently.”
• Screen for cognition, hearing, vision, mood, and upper-limb coordination, since these affect communication strategies and AAC access.

1. Sustained /a/
2. Repetition of syllables and multisyllabic words
3. Days of the week or automatic speech
4. Reading passage
5. 1 to 2 minute spontaneous conversation

• Intelligibility with familiar and unfamiliar listeners
• Speaking rate, pauses, phrase length
• Articulation precision
• Loudness and vocal quality
• Stress, pitch variation, and prosody
• Fatigue and effort
• Functional participation, such as Communication Participation Item Bank or patient-rated communication impact

2. Goals

• Increase unfamiliar-listener intelligibility in a recorded 1-minute conversation from 55% to 70%.
• Use a learned rate-control strategy in 80% of structured conversation opportunities.
• Independently use a repair strategy when misunderstood in 4 of 5 observed breakdowns.
• Use a low-tech or electronic AAC support during calls or in noisy settings.
• Maintain safe, efficient eating and drinking with an individualized swallowing plan, if dysphagia is present.

3. Treatment program

Session structure

1. Check-in, fatigue and goal rating: 5 minutes
2. Warm-up and calibration: 5 minutes
   • posture, comfortable breath, sustained phonation only if appropriate
3. Targeted practice: 15 to 20 minutes
   • rate, articulation, prosody, and/or voice
4. Functional speech: 15 to 20 minutes
   • phone call simulation, ordering food, work phrases, family conversation
5. Review and home plan: 5 minutes
   • choose one primary strategy, one short daily practice task

4. Communication-partner training

• Face the speaker and reduce television/background noise.
• Allow extra time and avoid finishing sentences unless asked.
• Ask for a repetition of the key word or offer a closed choice: “Did you mean Tuesday or Thursday?”
• Confirm the message: “I heard that you need the appointment moved to Friday.”
• Use writing, typing, pictures, or topic cues without treating the person as cognitively impaired.

5. Augmentative and alternative communication (AAC)

• Alphabet board, keyword notebook, written topic cards.
• “Please give me time to speak” card.
• Prewritten medical, transport, workplace, and emergency messages.

• Smartphone text-to-speech, predictive text, saved phrases.
• Voice banking, if the person wishes and current speech is suitable.
• Tablet-based communication app.
• Alternative access methods if tremor, incoordination, visual issues, or fatigue make typing difficult.

6. Review schedule

• Reassess the same speech samples after 4 to 6 weeks.
• Compare intelligibility, speaking rate, patient-rated effort, real-life participation, and successful use of strategies.
• Then schedule maintenance/review every 3 to 6 months, or earlier if speech, swallowing, breathing, or functional communication changes.
• Re-evaluate AAC access and partner strategies at each review.

Red flags for urgent medical/SLP review

• Coughing or choking with food, fluid, or saliva
• Wet/gurgly voice after drinking
• Unexplained weight loss, dehydration, or recurrent chest infection
• Rapidly worsening speech, breathlessness while speaking, or new severe voice change
• A sudden new neurological change, which is not typical of gradual SCA progression and needs urgent evaluation
