Post-Stroke Dysphagia: Why Home Exercise Matters

Post-stroke dysphagia affects approximately 40–70% of patients in the acute phase. With a structured home programme prescribed by a speech-language pathologist (SLP), patients can accelerate recovery of swallowing function and substantially reduce the risk of aspiration pneumonia.

Important: Every exercise in this guide must be individually assessed and approved by your SLP before you begin. Some exercises are contraindicated depending on the pattern of stroke damage. Always follow your SLP’s specific instructions over general guidance.

Core Swallowing Exercises

1. Tongue Protrusion and Lateral Movement

Purpose: Strengthens the tongue’s ability to propel food towards the pharynx.

Steps:

• Extend the tongue forward as far as possible; hold for 5 seconds, then relax.
• Move the tongue to the left corner of the mouth, hold for 3 seconds; repeat to the right.
• 10 repetitions per set, 3 sets daily.

2. Lip Closure Exercise

Purpose: Prevents food and liquid leaking from the lips; improves oral phase control.

Steps:

• Press the lips firmly together; hold for 5 seconds, then relax.
• Optional tool: place a clean tongue depressor or smooth stick between the lips (not teeth) and practise holding it using lip pressure only.
• 10 repetitions per set, 3 sets daily.

3. Jaw Range-of-Motion Exercise

Purpose: Restores jaw opening amplitude and improves chewing ability.

Steps:

• Slowly open the mouth to its full range; hold for 3 seconds, then slowly close.
• Movements should be gentle. Stop immediately and report to your SLP if you feel pain in the temporomandibular joint.
• 10 repetitions per set, 2 sets daily.

4. Vocal Cord Adduction Exercise

Purpose: Strengthens vocal cord closure to reduce aspiration risk.

Steps:

• Produce a sustained, loud “Ah——” sound for 5 seconds. The voice should be clear and strong.
• Follow with 3 deliberate (voluntary) strong coughs — not the reflex coughing that follows choking.
• 5 repetitions per set, 3 sets daily.

5. Mendelsohn Manoeuvre

Purpose: Trains laryngeal elevation and prolongs cricopharyngeal opening to improve bolus passage.

Steps:

• Perform a dry swallow (no food or liquid) and feel the larynx rise.
• Repeat; at the peak of laryngeal elevation, gently place your fingertips on the larynx and consciously hold it at the highest point for 3–5 seconds before allowing it to descend.
• This is an advanced technique. Always practise first under SLP supervision before attempting at home. 10 repetitions daily.

Posture Adjustments for Safe Eating

Correct posture can significantly reduce aspiration risk even while swallowing function is recovering.

General Principles

• Sit fully upright at 90°: Always eat sitting straight up with back support. Keep the head in midline.
• Stay upright after meals: Remain seated for at least 30–60 minutes after eating to prevent reflux into the airway.
• Quiet environment: Turn off the television and minimise distractions so the patient can focus on swallowing.

For Post-Stroke Patients with Hemiplegia

• Support the affected (weaker) side with pillows to maintain a midline head position.
• Introduce food from the stronger side of the mouth.
• If your SLP prescribes a head-turn towards the affected side, follow this precisely — this technique closes off the weaker pharyngeal wall and directs the bolus through the stronger pathway.

Safety Guidance for Home Practice

Stop the exercise session immediately and contact your SLP if:

• The patient coughs persistently during or after exercises
• The voice becomes hoarse or sounds “wet” or “gurgly”
• The patient develops a fear of eating or swallowing
• Body temperature rises (may indicate aspiration pneumonia developing)

Hong Kong Rehabilitation Resources

Hospital Authority Services

Post-stroke speech therapy is available through:

• Acute and rehabilitation inpatient phase: Ward SLP assessment and treatment
• Post-discharge: Referral to Geriatric Day Hospital or specialist outpatient speech therapy
• Stable phase: Some clusters offer community speech therapy services

Community Resources

• Hong Kong Society for Rehabilitation: Stroke rehabilitation programmes for community-dwelling patients
• SWD Integrated Home Care Services (Type II): Includes rehabilitation support elements
• District Rehabilitation Training Centres: Some districts offer subsidised or free community training

When Can the Diet Level Be Advanced?

Diet level changes (IDDSI level upgrades) must only be made after formal re-assessment by an SLP. You may request a re-assessment when:

• It has been 3–6 months post-stroke and the patient has shown consistent functional improvement
• SLP-documented progress in home exercise sessions
• Reduced meal intake due to the current diet texture level is affecting nutrition

Do not self-upgrade the diet level because the patient appears to be swallowing better — silent aspiration can occur without visible coughing, even when patients feel they are managing well.
