Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders, also known as dysphagia. NMES is a non-invasive procedure that involves placing electrodes on the skin of the neck and/or face, delivering a low-level electric current to activate the muscles used for feeding and swallowing. This therapy has been cleared by the Food and Drug Administration (FDA) and is often used in conjunction with traditional treatments to improve swallowing and feeding skills in children and adults. While the effectiveness of NMES for dysphagia is still being studied, initial research suggests that it can improve swallowing function, strengthen swallowing muscles, and reduce the risk of aspiration.

Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders (dysphagia)
Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders, also known as dysphagia. Dysphagia is a condition characterised by difficulty swallowing, where food or liquids cannot pass easily from the mouth to the throat and down into the oesophagus to the stomach. This can result in food or drink being swallowed incorrectly and can lead to poor nutrition, weight gain, or pneumonia. NMES is a specialised form of electrical stimulation therapy designed to treat dysphagia. It involves placing electrodes on the skin of the neck and/or face, over the muscles used for chewing and swallowing, and delivering a small electric current to activate these muscles.
NMES is a non-invasive procedure, meaning it does not involve any incisions or entry into the body. It is typically administered by a speech and language pathologist or an occupational therapist, in conjunction with traditional treatments for dysphagia. The frequency and duration of NMES treatment may vary depending on the patient's specific condition and goals. In some cases, a videofluoroscopy swallow study may be conducted before and after treatment to evaluate the patient's swallowing skills and measure any improvements.
Several studies have demonstrated the long-term therapeutic effects of NMES, which can last from two to four weeks. NMES can improve swallowing function by strengthening the swallowing muscles, rehabilitating the swallowing reflex, and regulating cortical excitability. It has been found to increase the sensory input of the oral pharyngeal region and enhance the sensitivity of muscle contractions. NMES has been particularly effective in treating post-stroke dysphagia, where it has been shown to improve swallowing initiation and reduce the risk of penetration and aspiration.
While NMES has shown promising results, the evidence regarding its effectiveness for dysphagia is still being evaluated. Clinicians must consider the specific patient, any contraindications or precautions, and the potential benefits or risks associated with using NMES as a treatment tool. Side effects of NMES may include redness and irritation to the skin, but these typically resolve within 24 to 48 hours with the use of topical moisturisers.

NMES uses electrodes to deliver a small electric current to the face and neck
Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders, also known as dysphagia. Dysphagia is the inability of food or liquids to pass easily from the mouth, through the throat, and down into the oesophagus to the stomach during the process of swallowing. This can lead to serious health issues, such as poor nutrition, weight gain, or pneumonia.
NMES is a non-invasive procedure that uses electrodes to deliver a small electric current to the face and neck. The electrodes are placed on the skin, over the muscles used for chewing and swallowing. This low-level electric current stimulates and activates these muscles, improving the patient's swallowing and feeding skills. The treatment is often used alongside traditional therapies and can be particularly effective for children with swallowing disorders.
Before NMES treatment begins, a videofluoroscopy swallow study may be required to assess the patient's swallowing abilities and determine the severity of their dysphagia. This information is used to set goals and decide on the frequency of treatment sessions. During a typical NMES session, the patient may experience a tingling or pulling sensation as the electric current stimulates the muscles. The treatment is generally well-tolerated, with the most common side effect being temporary skin redness and irritation.
Several studies have demonstrated the long-term therapeutic effects of NMES. This form of therapy can improve swallowing function by strengthening the swallowing muscles, rehabilitating the swallowing reflex, and regulating cortical excitability. It can also increase sensory input in the oral pharyngeal region, enhancing the sensitivity of muscle contractions. NMES has been shown to be particularly effective for patients with post-stroke dysphagia, improving their swallowing initiation and reducing the risk of penetration and aspiration.

The treatment is non-invasive and FDA-approved
Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders, also known as dysphagia. The treatment is non-invasive and FDA-approved.
NMES uses a low-level electric current to stimulate the muscles used for chewing and swallowing. Electrodes are placed on the skin of the neck and/or face, over the muscles responsible for these functions. The treatment is painless, with the electric current starting as a slight tingling sensation and building to a pulling sensation.
NMES is a safe and effective treatment for dysphagia, with no known associated risks. Side effects are minimal and typically limited to redness and irritation of the skin, which can be easily treated with a topical moisturiser.
The treatment is often used in conjunction with traditional therapies, such as feeding and oral motor therapies and exercises, to improve swallowing and feeding skills. It is particularly beneficial for children with swallowing disorders, as well as post-stroke patients, by improving swallowing initiation and reducing the risk of aspiration.
As an FDA-approved treatment, NMES devices are regulated and subject to specific contraindications and precautions. These include considerations for patients with pacemakers, implanted electrodes, or certain medical conditions. Prior to marketing and selling NMES devices, manufacturers must file a premarket notification with the FDA, providing detailed information about the device and its intended use.

NMES can improve swallowing function by strengthening the swallowing muscles
Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders, also known as dysphagia. This condition, dysphagia, is characterised by difficulties in swallowing, resulting in the inability to effectively pass food or liquids from the mouth to the throat and down into the oesophagus for further digestion. Dysphagia can lead to serious complications such as poor nutrition, weight gain, or even pneumonia.
NMES is a non-invasive therapy that employs a low-level electric current to stimulate and activate the muscles responsible for chewing and swallowing. This is achieved by placing electrodes on the skin of the neck and/or face, targeting the muscles involved in the feeding process.
NMES can effectively improve swallowing function by strengthening the swallowing muscles. Several studies have demonstrated the long-term therapeutic benefits of NMES, which can persist for 2–4 weeks after treatment. This strengthening effect enhances the overall swallowing function, making it easier for patients to swallow and reducing the risk of associated complications.
In addition to muscle strengthening, NMES therapy can also rehabilitate the swallowing reflex and regulate cortical excitability. Furthermore, some studies suggest that NMES increases sensory input in the oral pharyngeal region and enhances the sensitivity of muscle contractions. These combined effects contribute to improved swallowing initiation and overall swallowing function.
The use of NMES has been particularly beneficial for patients with post-stroke dysphagia, where more than half of stroke survivors develop swallowing difficulties. NMES has been shown to significantly improve swallowing performance in these patients, reducing the risk of aspiration and improving their quality of life.

NMES may also increase the sensory input of the oral pharyngeal region
Neuromuscular electrical stimulation (NMES) is a treatment for swallowing disorders, also known as dysphagia. It is a non-invasive procedure where electrodes are placed on the skin of the neck and/or face, delivering a low-level electric current to activate the muscles used for feeding and swallowing. This therapy has been cleared by the Food and Drug Administration (FDA) and is often used alongside traditional treatments to improve swallowing and feeding skills.
NMES has been shown to improve swallowing initiation and function in patients with dysphagia, particularly those who have experienced a stroke. It can also reduce the risk of aspiration, which is a common complication of dysphagia. Furthermore, NMES has long-term therapeutic effects, strengthening the swallowing muscles, rehabilitating the swallowing reflex, and regulating cortical excitability.
The increased sensory input from NMES may also provide additional benefits beyond swallowing. The stimulation of sensory nerves in the oral and pharyngeal regions can potentially have a positive impact on taste and temperature perception, and overall sensory function. This could be especially beneficial for individuals with sensory impairments or those recovering from sensory loss due to various medical conditions.
While NMES has shown promising results, it is important to note that it may not be suitable for everyone. Clinicians must carefully evaluate each patient's condition and consider any precautions or contraindications before incorporating NMES into their treatment plan. More systematic research is needed to fully understand the benefits of NMES for specific patient populations and to optimize its use in clinical practice.
