Swallowing Post-Stroke: Regaining Function And Independence

Swallowing problems, or dysphagia, are common after a stroke, with over 50% of stroke victims experiencing difficulty. Dysphagia can cause serious complications, such as aspiration, where food or drink enters the lungs, leading to pneumonia or other chest infections. It can also impact a person's nutrition and hydration, and their ability to socialise. However, most stroke survivors will recover their swallowing function within a week, and the majority of those who don't will recover within six months. A range of swallowing exercises can help to restore the ability to swallow, and speech pathologists and dietitians can advise on the best course of treatment.

Dysphagia, or difficulty swallowing, is common after a stroke and can lead to life-threatening complications

Dysphagia, or difficulty swallowing, is a common complication following a stroke, affecting over 50% of stroke victims. It can lead to serious and life-threatening complications such as aspiration and pneumonia. Aspiration occurs when food or liquid enters the lungs instead of the oesophagus, which can cause chest infections and pneumonia.

The condition can be caused by the stroke's impact on the brain, which controls the swallowing muscles. This can result in weak or uncoordinated muscles, making swallowing difficult. Additionally, a stroke can affect other motor functions that indirectly impact swallowing. For example, if a patient is unable to sit up straight, swallowing can become more challenging.

Dysphagia can also impede a stroke survivor's ability to eat and drink, leading to malnutrition and dehydration. It can also negatively impact their social life, as dining and mealtimes become more difficult.

However, the majority of people with dysphagia following a stroke will recover their swallowing function within a week, and it is often temporary. Speech pathologists play a crucial role in diagnosing and treating dysphagia, conducting swallowing tests and recommending appropriate therapies. These may include swallowing exercises to strengthen the relevant muscles and improve respiratory function. Dieticians can also provide valuable support by recommending suitable foods and liquids that are easier to swallow.

It is important for stroke survivors and their caregivers to be aware of the signs of dysphagia and to seek help from medical professionals. With early diagnosis, appropriate treatment, and a strong support system, most patients can fully recover their swallowing function and improve their quality of life.

Diagnosing and treating swallowing issues early in recovery is important to prevent aspiration and pneumonia

Swallowing issues after a stroke, known as dysphagia, can lead to serious health complications such as pneumonia and lung infections if not identified and managed. Diagnosing and treating swallowing issues early in recovery is therefore crucial to prevent aspiration and pneumonia.

Diagnosis

A speech-language pathologist will typically assess a patient's swallowing ability through swallowing tests. These tests may involve observing the patient eating and drinking or using x-rays and/or endoscopic evaluations.

Treatment

If a patient is diagnosed with dysphagia, a speech-language pathologist will work with them to improve their swallowing ability. This may involve practicing various swallowing exercises, such as the effortful swallow, the Mendelsohn maneuver, and the supraglottic swallow.

In addition to these exercises, speech-language pathologists may recommend the following strategies to help with swallowing:

• Eating small bites very slowly
• Sitting upright in a chair at a table to eat
• Alternating solids and liquids
• Tucking the chin in and down or turning the head toward the affected side to help block the airway

Prevention

To prevent aspiration and pneumonia, it is important to be able to identify the signs of swallowing problems, which include:

• Coughing or choking when eating or drinking
• Bringing food back up, sometimes through the nose
• Food or drink going down the wrong way
• Feeling that food is stuck in the throat
• Inability to keep food or drink in the mouth
• Food or drink left in the mouth after swallowing
• Inability to chew food properly
• A croaky or 'wet' sounding voice
• Saliva escaping from the mouth
• Taking a long time to swallow or finish a meal
• Needing to swallow a lot or clear the throat repeatedly
• Shortness of breath when swallowing

Swallowing exercises can help stroke survivors recover from dysphagia and improve their ability to swallow safely

Dysphagia, or difficulty swallowing, is a common complication of stroke, affecting over 50% of stroke survivors. This can have a significant impact on a person's quality of life, as it may no longer be possible to share meals with family and friends. In addition, dysphagia can lead to serious health complications such as aspiration pneumonia, malnutrition, and dehydration.

The good news is that most stroke survivors recover their swallowing function within a week, and only about 11-13% continue to experience dysphagia after six months. Furthermore, swallowing exercises have been shown to be effective in helping stroke survivors recover from dysphagia and improve their ability to swallow safely.

There are several swallowing exercises that can be performed to strengthen the muscles involved in swallowing and improve coordination. These exercises should be performed under the guidance of a speech therapist or occupational therapist, who can assess the patient's specific needs and develop an appropriate treatment plan. Here are some examples of swallowing exercises:

• Effortful swallow: This exercise involves practicing pushing the tongue forcefully against the hard palate, simulating the clearing of a bolus.
• Mendelsohn maneuver: This exercise uses the hand to gently push against the larynx and open the esophagus during swallowing.
• Supraglottic swallow: This involves taking a deep breath, holding it, swallowing a small bite of food, coughing to clear the airway, and then exhaling.
• Shaker exercise: Lying on your back, raise your head off the ground until you can see your toes. Hold this position for a few seconds, then lower your head. Repeat this movement several times throughout the day.
• Resistive tongue exercise: Push your tongue firmly against the roof of your mouth, cheeks, and a spoon or tongue depressor. Hold for 10 seconds and repeat 5 times, 2 times per day.

In addition to these exercises, it is important to work with a dietitian to ensure the patient is consuming appropriate foods and liquids that are easier to swallow. It is also crucial for caregivers to be involved in the treatment plan and to recognize the signs of dysphagia, such as coughing or throat clearing, needing extra liquid to wash down food, or food sticking in the throat.

Speech-language pathologists play a crucial role in diagnosing and treating swallowing disorders after a stroke

Speech-language pathologists (SLPs) are essential in diagnosing and treating swallowing disorders, known as dysphagia, after a stroke. Dysphagia is a common complication of strokes, affecting over 50% of stroke survivors. It can lead to serious health issues such as aspiration, pneumonia, and malnutrition, as well as negatively impacting a person's social life.

SLPs play a crucial role in assessing and diagnosing dysphagia. They conduct swallowing tests to evaluate the patient's ability to swallow without choking and make recommendations for treatment and management. These tests may include observing the patient eating and drinking, assessing oral motor function, and performing special tests such as modified barium swallows or endoscopic assessments.

In terms of treatment, SLPs can provide a range of compensatory techniques and direct treatment strategies to improve the patient's swallowing function and safety. Compensatory techniques include positioning strategies, swallowing maneuvers, and food and liquid consistency modifications. Direct treatment involves exercises to improve the range of motion, coordination, and strength of the muscles involved in swallowing, such as the jaw, lips, tongue, and soft palate.

SLPs also play a vital role in patient education and caregiver involvement. They can provide guidance on safe eating and drinking practices, such as specific postures and food types that can facilitate easier swallowing. Additionally, they can empower caregivers to identify signs of swallowing difficulties and ensure adherence to the treatment plan.

Overall, the involvement of SLPs is crucial in diagnosing, treating, and managing dysphagia in stroke survivors. Their expertise helps improve patients' swallowing function, reduce the risk of complications, and enhance their overall quality of life.

Dysphagia can increase the risk of death and nursing home admissions, highlighting the importance of early intervention

Dysphagia, or difficulty swallowing, is a common complication of a stroke, affecting over 50% of stroke survivors. While most people recover their swallowing function within a week, some experience long-term difficulties. Dysphagia can have serious consequences, including an increased risk of death and nursing home admissions, making early intervention crucial.

Those with dysphagia are at a higher risk of aspiration, where food or liquid enters the lungs instead of the oesophagus. This can lead to coughing, choking, and chest infections such as pneumonia. Aspiration can be life-threatening, especially if the person has a reduced cough reflex, which is common after a stroke.

Research has shown that dysphagia during the acute phase of a stroke is associated with increased mortality, particularly within the first three months. A study by Smithard et al. found that residence in a nursing home was more likely for those who failed a swallow test during the first week of their stroke, with statistical significance at three months and years four and five. This indicates that dysphagia can lead to increased institutionalisation rates in the long term.

Additionally, dysphagia can result in longer and more expensive hospital stays. A study led by researchers from the University of Wisconsin School of Medicine and Public Health found that patients aged 45 or older with dysphagia had nearly double the chance of dying in the hospital. They also had longer hospital stays and were more likely to require nursing home care upon discharge.

The impact of dysphagia on quality of life cannot be overstated. It can affect a person's ability to eat, drink, and socialise. Early intervention is crucial to minimise these risks and improve outcomes for stroke survivors. Working with experts such as dietitians and speech pathologists can help manage dysphagia and improve swallowing function.
