Muscle tension dysphagia (MTDg) is a diagnosis of exclusion
Dysphagia is a medical term used to describe difficulty swallowing food, liquids, pills, and/or saliva. While the cause is sometimes obvious, such as following a stroke or surgery, some swallowing problems have no clear underlying cause. Muscle tension dysphagia (MTDg) is a type of dysphagia that is caused by a muscle tension imbalance in the upper body, including the larynx, neck, jaw, tongue, and/or upper torso. This tension can impact an individual's ability to swallow.
MTDg is considered a diagnosis of exclusion, meaning that it is only diagnosed when other potential causes of dysphagia have been ruled out. This is because the symptoms of MTDg can overlap with various other conditions, and it is important to ensure that the patient receives an accurate diagnosis and appropriate treatment. For example, other causes of dysphagia include laryngopharyngeal reflux (LPR), gastroesophageal reflux (GERD), dry mouth, oral and dental health issues, and side effects of medication. In addition, dysphagia can be caused by issues with the cervical spine, such as degenerative disorders of the cervical neck ligaments, or compression or interruption of the vagus nerve, which is involved in the swallowing process.
To diagnose MTDg, a comprehensive evaluation is conducted to rule out other potential causes. This may include a detailed patient history, physical examinations, and various instrumental swallowing and voice assessments. For example, a Modified Barium Swallow Study (MBSS) is a video x-ray study that assesses the patient's ability to swallow food and liquids. Another assessment is a Fiberoptic Endoscopic Evaluation of Swallowing (FEES), which involves passing a small tube through the nose and into the throat to evaluate the swallowing process. These assessments help to ensure that MTDg is the correct diagnosis before proceeding with treatment.
Once MTDg is diagnosed, treatment options can be explored. Studies have shown that therapy aimed at reducing laryngeal muscle tension can be effective, with many patients experiencing a significant reduction in dysphagia symptoms. Other treatment options for dysphagia caused by neck issues may include exercises to strengthen the swallowing muscles, electrostimulation of the swallowing muscles, and a modified diet. Atlas therapy, which focuses on correcting misalignments in the cervical spine, may also be beneficial for some patients.
In summary, MTDg is a diagnosis of exclusion, requiring a comprehensive evaluation to rule out other potential causes of dysphagia. This ensures that patients receive an accurate diagnosis and appropriate treatment for their swallowing difficulties, which can have a significant impact on their quality of life.

MTDg is caused by a muscle tension imbalance in the upper body
Muscle Tension Dysphagia (MTDg) is a swallowing disorder caused by a muscle tension imbalance in the upper body, including the larynx, neck, jaw, tongue, and upper torso. This condition can significantly impact a person's quality of life, and in some cases, lead to various health complications.
MTDg is often underdiagnosed, and patients with this condition typically report a significant impact on their ability to swallow solids, experiencing throat discomfort, and a sensation of food sticking in their throat. The diagnosis of MTDg is made through exclusion, meaning that other possible causes of dysphagia, such as oesophageal webbing and gastroenterological malignancies, must be ruled out first.
The underlying cause of MTDg is a muscle tension imbalance in the upper body. This imbalance can be triggered by various factors, including irritants (such as reflux or toxic exposure), emotional concerns, anxiety, and improper or excessive use of upper body muscles. The vagus nerve, which plays a crucial role in swallowing, can be affected by neck issues, leading to swallowing difficulties.
Neck pain, a common symptom of MTDg, can be caused by different clinical conditions that require interventions beyond physiotherapy. It is important to identify the underlying causes to determine the appropriate treatment approach. In some cases, neck pain and swallowing difficulties may be related to degenerative disorders of weakened cervical neck ligaments or cervical disc disease.
Treating neck instability and correcting spinal deformities can help improve swallowing difficulties. Atlas therapy focuses on correcting misalignments in the cervical spine, particularly the atlas vertebra, to alleviate pressure on the nervous system and improve swallowing function. Overall, MTDg is a complex condition that requires a comprehensive evaluation to ensure effective patient-centred diagnosis and care.

MTDg symptoms include difficulty swallowing solids, throat discomfort, and food sticking in the throat
Muscle Tension Dysphagia (MTDg) is a swallowing disorder caused by a muscle tension imbalance in the upper body, including the larynx, neck, jaw, tongue, and/or upper torso. MTDg is often underdiagnosed, and patients report a significant impact on their quality of life due to swallowing difficulties. The most common symptoms of MTDg are difficulty swallowing solids, throat discomfort, and the sensation of food sticking in the throat.
MTDg is diagnosed as a condition of exclusion, meaning that other possible causes of dysphagia must be ruled out first. These include oesophageal webbing, malignancies of gastroenterologic nature, neurological diseases such as Parkinson's and other dementias, and other muscle tension-based laryngeal disorders like irritable larynx syndrome.
To diagnose MTDg, a comprehensive evaluation is conducted by a care team, including an ENT/laryngologist and a speech pathologist. This evaluation involves taking a detailed history and performing various instrumental swallowing and voice assessments, such as a Fiberoptic Endoscopic Evaluation of Swallowing (FEES), Modified Barium Swallow Study (MBSS), and/or videostroboscopy.
The treatment for MTDg focuses on reducing laryngeal muscle tension. Studies have shown that therapy aimed at unloading laryngeal muscle tension has resulted in a significant reduction in dysphagia symptoms. Additionally, postural modifications can help in the rehabilitation of patients with MTDg by improving the speed and safety of swallowing.
It is important to note that neck pain and swallowing difficulties can also be related to other conditions, such as viral or bacterial pharyngitis (e.g., strep throat), muscle spasms, torticollis, and various clinical conditions that require interventions beyond physiotherapy. A differential diagnosis is crucial to ensure appropriate referrals for therapeutic interventions.

Treatment for dysphagia caused by neck issues includes atlas therapy
Dysphagia is a swallowing disorder that can be caused by a variety of issues, including muscle tension in the neck. While dysphagia has many causes, cervicogenic dysphagia, which stems from neck issues, plays a crucial role in the condition. The cervical spine, particularly the atlas (C1) vertebra, is a critical area where swallowing-related nerves pass through and muscles attach. As a result, pain, postural misalignment, trauma, or degenerative changes in the neck can negatively affect the swallowing process, impairing both sensory and motor functions.
Atlas therapy is a treatment option for dysphagia caused by neck issues. This therapy not only targets the atlas vertebra but also assesses the alignment of the entire cervical spine and surrounding tissues. By addressing overall dysfunction in the neck region, atlas therapy provides a comprehensive approach to relieving swallowing difficulties.
In addition to atlas therapy, there are other treatment options available for dysphagia caused by neck issues. These may include conservative care treatments, swallowing exercises, electrostimulation of the swallowing muscles, and a modified diet. For example, neuromuscular electrical stimulation (NMES) provides specific electrical impulses to help train the swallowing muscles, while respiratory muscle strength training (RMST) improves breathing, cough strength, and swallowing.
Postural modification is another important aspect of treating dysphagia caused by neck issues. Forward head posture, for instance, has been linked to increased tension in the neck muscles and ligaments, which can impact swallowing. By addressing forward head posture and other postural issues, individuals can improve the speed and safety of swallowing.
In some cases, medical interventions such as steroid injections or regenerative proliferative injections may be recommended to treat underlying conditions contributing to dysphagia. It is important to work with a healthcare professional to determine the most appropriate treatment approach for each individual case of dysphagia caused by neck issues.

Dysphagia can be caused by damage to the vagus nerve
Tight neck muscles can cause dysphagia, or difficulty swallowing. This condition is called muscle tension dysphagia and is diagnosed only when other causes for dysphagia have been ruled out. It is characterised by excess tension in the muscles of the larynx, neck, jaw, tongue, or chest, impacting an individual's ability to swallow.
Dysphagia can also be caused by damage to the vagus nerve, which is the tenth of twelve cranial nerves and contains 75% of the parasympathetic nervous system's nerve fibres. The vagus nerve carries signals between the brain, heart, and digestive system, playing a key role in managing involuntary functions like heart rate, breathing, and digestion. When the vagus nerve is damaged, it can lead to gastroparesis, where food is unable to move from the stomach into the intestines. This can result from diabetes, viral infections, abdominal surgery, or scleroderma.
In the context of dysphagia, damage to the vagus nerve can cause swallowing difficulties. The vagus nerve innervates most of the pharynx and larynx mucosal surfaces, as well as the muscles that elevate the palate and cause the larynx to contract. Compression or interruption of the vagus nerve signals due to neck instability can lead to swallowing difficulties. This is known as cervicogenic dysphagia and is associated with degenerative disorders of weakened cervical neck ligaments.
The superior laryngeal nerve (SLN) and the recurrent laryngeal nerve (RLN) are branches of the vagus nerve that are specifically involved in swallowing. Lesions on either of these nerves are associated with increased aspiration, which is a common diagnostic endpoint for dysphagia. Unilateral SLN lesions, for example, can decrease sensitivity to the swallow stimulus, requiring a bigger bolus to trigger the swallow reflex. This results in longer swallow transit times.
In summary, dysphagia is a complex condition that can arise from various causes, including tight neck muscles and damage to the vagus nerve. When the vagus nerve is compromised, it can lead to swallowing difficulties due to its role in coordinating the complex process of swallowing.
