Swallowing Problems After a Stroke? Why Specialized Swallowing Therapy Matters
Eating and drinking are things most of us do without giving them much thought. But after a stroke, something as simple as taking a sip of water or enjoying a meal with family can suddenly become difficult, frustrating, or even frightening.
Difficulty swallowing is called dysphagia. It is a common complication of stroke, affecting nearly half of people who experience one. Dysphagia can make it difficult to eat and drink safely, get enough nutrition and fluids, and enjoy the social experiences that come with sharing a meal.
The good news? Swallowing therapy can help. And research continues to show us new ways to improve treatment and support recovery.
At True Self Speech Therapy, swallowing disorders are one of our areas of specialization. We work with adults experiencing swallowing difficulties related to stroke, neurological conditions, head and neck cancer, and other medical conditions. Our approach combines clinical expertise, evidence-based treatment, and a focus on helping people get back to the foods, drinks, and activities that matter to them.
Why Does a Stroke Affect Swallowing?
Swallowing is a surprisingly complex process. It requires many muscles and nerves to work together in a coordinated sequence. Your brain controls this process, helping move food and liquid from your mouth, through your throat, and into your esophagus (the tube that carries food to your stomach).
A stroke can damage the parts of the brain responsible for coordinating these movements. When that happens, food or liquid may have difficulty moving through the swallowing pathway. In some cases, it can enter the airway instead of the esophagus. This is called aspiration.
Aspiration can increase the risk of serious complications, including pneumonia.
Some common signs of swallowing difficulties include:
Coughing or choking when eating or drinking.
A wet, gurgly-sounding voice after swallowing.
Food feeling stuck in your throat.
Taking much longer than usual to finish meals.
Difficulty swallowing pills.
Avoiding certain foods or liquids because they are difficult to swallow.
Unexplained weight loss or dehydration.
Repeated respiratory infections or pneumonia.
One important thing to know: Not everyone who aspirates coughs or chokes. Some people experience silent aspiration, meaning food or liquid enters the airway without an obvious outward sign.
If you or a loved one has experienced a stroke and is having difficulty swallowing, an evaluation by a speech-language pathologist (SLP) with expertise in swallowing disorders is an important step.
What Does Swallowing Therapy Actually Involve?
Swallowing therapy is much more than doing exercises. A skilled speech-language pathologist evaluates how a person swallows, identifies areas of difficulty, and develops a treatment plan based on their specific needs.
Treatment may include several approaches:
1. Swallowing exercises
Specific exercises can help strengthen or improve coordination of the muscles involved in swallowing. Examples include the Shaker exercise, chin tuck against resistance (CTAR), and effortful swallowing.
2. Compensatory strategies
Sometimes changing how a person eats or drinks can make swallowing easier or safer. This may involve adjusting posture, changing the size of bites or sips, or using a specific swallowing technique.
Neuromuscular Electrical Stimulation (NMES)
This is an approach that has received increasing attention in swallowing rehabilitation.
NMES uses small electrical impulses delivered through electrodes placed on the skin of the neck. These impulses stimulate nerves that activate muscles involved in swallowing. The goal is to support muscle activity and provide additional sensory input while the person participates in swallowing exercises.
What Does the Research Say About Electrical Stimulation for Swallowing?
A recent randomized controlled trial by Chi-Nung Lin and Chia-Lung Shih, titled Efficacy of Neuromuscular Electrical Stimulation Combined with Traditional Swallowing Therapy in Acute Stroke Patients with Dysphagia, investigated whether adding NMES to traditional swallowing therapy could improve recovery after a stroke.
The researchers studied 57 adults with acute or subacute stroke who had severe swallowing difficulties and depended on feeding tubes for nutrition.
Participants were divided into two groups:
Group 1: Received traditional swallowing therapy combined with neuromuscular electrical stimulation.
Group 2: Received traditional swallowing therapy with sham (minimal) electrical stimulation.
Both groups were scheduled to receive 10 treatment sessions over two weeks. Traditional therapy included swallowing exercises, oral motor exercises, sensory stimulation, and techniques to improve swallowing muscle function.
The researchers measured swallowing function, swallowing symptoms, and quality of life before treatment, during treatment, and after treatment.
What Did the Researchers Find?
There were several encouraging findings.
1. People receiving electrical stimulation made greater improvements in their ability to eat and drink by mouth.
The researchers used a scale called the Functional Oral Intake Scale (FOIS) to measure how much a person could safely take by mouth.
This scale ranges from Level 1 (nothing by mouth) to Level 7 (a full oral diet without restrictions).
Both groups improved, but the group receiving electrical stimulation alongside traditional therapy made significantly greater progress. Two weeks after treatment ended, approximately 85% of the NMES group had reached a level of oral intake considered sufficient to meet their nutritional needs, compared with approximately 42% of the traditional therapy group.
This is an especially important finding for people who are dependent on feeding tubes after a stroke. It suggests that combining electrical stimulation with swallowing exercises may help some individuals make faster progress toward eating and drinking by mouth.
2. Swallowing symptoms improved more in the electrical stimulation group.
The researchers also used a questionnaire called the Eating Assessment Tool (EAT-10) to measure swallowing-related symptoms. Both groups reported improvements, but the group receiving electrical stimulation experienced significantly greater reductions in swallowing symptoms at each follow-up assessment. In other words, adding electrical stimulation appeared to provide additional benefits beyond traditional swallowing exercises alone.
3. Quality of life improved, although the benefits were less clear.
Swallowing difficulties affect much more than the physical act of eating. They can make people anxious about choking, limit food choices, interfere with social activities, and take away the enjoyment of meals.
Both groups experienced improvements in swallowing-related quality of life. However, the additional benefit of electrical stimulation was not statistically significant at the later follow-up assessments. This is a helpful reminder that swallowing recovery involves more than improving muscle function. Regaining confidence, independence, and enjoyment of meals is also important.
What Does This Mean for Someone Experiencing Swallowing Difficulties?
This study adds to the growing evidence that combining different treatment approaches may improve swallowing recovery after a stroke. It also reinforces an important point: Traditional swallowing therapy works, and specialized treatment techniques may offer additional benefits for certain individuals.
However, there are some limitations to keep in mind. This was a relatively small study conducted at one hospital, and participants were followed for only a short period. The study focused specifically on people with severe swallowing difficulties following a recent stroke, so its findings cannot automatically be applied to everyone with dysphagia.
The researchers also did not use instrumental swallowing studies, such as a modified barium swallow study (MBSS/VFSS) or a FEES (Fiberoptic Endoscopic Evaluation of Swallowing), to directly examine swallowing physiology.
More research is needed to understand the long-term benefits and determine which patients are most likely to benefit from electrical stimulation.
Still, the findings support the value of comprehensive, individualized swallowing rehabilitation.
Why Specialized Swallowing Therapy Matters
Not all swallowing difficulties are the same. Someone recovering from a stroke may have very different needs from someone living with Parkinson's disease, multiple sclerosis, ALS, or someone experiencing swallowing problems following head and neck cancer treatment.
Effective dysphagia treatment requires a thorough understanding of swallowing anatomy, physiology, neurological conditions, and the many treatment approaches available.
At True Self Speech Therapy, we specialize in adult swallowing rehabilitation. We believe that people deserve more than a generic list of swallowing exercises or recommendations to simply avoid certain foods.
Our approach includes:
Individualized swallowing evaluations: We take the time to understand your medical history, symptoms, eating habits, and personal goals.
Evidence-based treatment: We use research-supported swallowing exercises and specialized treatment approaches selected according to your needs.
Specialized equipment and techniques: Our clinicians have training in approaches such as VitalStim neuromuscular electrical stimulation and the McNeill Dysphagia Therapy Program (MDTP).
Functional, meaningful goals: We want to help you do more than improve a score on a swallowing assessment. We want to help you return to the meals, foods, and social experiences that are important to you.
Education for family members and caregivers: We work with care partners so they understand swallowing recommendations and can support progress outside of therapy.
We also recognize that swallowing difficulties can be stressful for the entire family. Our smaller, locally owned practice allows us to provide personalized attention and build relationships with the people we serve.
