What is spasmodic dysphonia?
In spasmodic dysphonia, the muscles inside the vocal folds experience sudden involuntary movements called spasms which interfere with the ability of the cords to vibrate and produce voice.
Spasmodic dysphonia causes voice breaks and can give the voice a tight, strained quality. People with spasmodic dysphonia may have occasional breaks in their voice that occur once every few sentences. Usually, however, the disorder is more severe and spasms may occur on every other word, making a person\’s speech very difficult for others to understand.
Types of spasmodic dysphonia
and Adductor spasmodic dysphonia is the most common form of spasmodic dysphonia. It is characterized by spasms that cause the vocal cords to slam together and stiffen. These spasms make it difficult for the vocal folds to vibrate and produce sounds. Words are often cut off or are difficult to start because of muscle spasms. Therefore, speech may be choppy. The voice of someone with adductor spasmodic dysphonia is commonly described as strained or strangled and full of effort. Stress often makes the muscle spasms more severe.
Causes of spasmodic dysphonia
The exact cause of spasmodic dysphonia is unknown. Because the voice can sound normal or near normal at times, spasmodic dysphonia was once thought to be psychogenic, or originating in a person\’s mind, rather than from a physical cause. In rare cases, psychogenic forms of spasmodic dysphonia do exist; however, in most instances, the muscle spasms are caused by abnormalities in the central nervous system.
A disorder that involves involuntary muscle contractions is also called a dystonia; therefore, another name for spasmodic dysphonia is laryngeal dystonia. Spasmodic dysphonia is considered a form of focal dystonia, a neurological disorder that affects muscle tone in one part of the body. Writer\’s cramp is another type of focal dystonia. Other dystonias can affect multiple regions of the body or the entire body.
Spasmodic dysphonia may co-occur with other dystonias that cause involuntary and repetitious movement of such muscles as the eyes; face, body, arms, and legs; jaws, lips, and tongue; or neck.
Spasmodic dysphonia is thought to be caused by abnormal functioning in an area of the brain called the basal ganglia. The basal ganglia consist of several clusters of nerve cells deep inside the brain. They help coordinate movements of the muscles throughout the body. Recent research has found abnormalities in other regions of the brain, including the brainstem.
How to make the Diagnosis
The ENT surgeon examines the vocal cords by fiberoptic nasolaryngoscopy to evaluate the structure and movement of vocal cords during speech and other activities. The speech-language pathologist evaluates the types of voice symptoms to see if they are characteristic of spasmodic dysphonia or other voice disorders and voice quality. The neurologist evaluates the patient for signs of other muscle movement disorders.
Conventional treatment of SD
The most common treatment for spasmodic dysphonia is the injection of very small amounts of botulinum toxin directly into the affected muscles of the larynx. Botulinum toxin is produced by Clostridium botulinum, the same bacterium that occurs in improperly canned foods and honey. The toxin weakens muscles by blocking the nerve impulse to the muscle. Botulinum toxin injections generally improve the voice for a period of three to four months, after which the voice symptoms gradually return.
Repeat injections are necessary to maintain a good speaking voice. Initial side effects, including a temporary weak, breathy voice and occasional swallowing difficulties, usually subside after a few days to a few weeks. Botulinum toxin will relieve symptoms of most cases of adductor spasmodic dysphonia and is helpful in many cases of abductor spasmodic dysphonia.
Speech therapy is another form of treatment that may work to reduce symptoms in mild cases. Other people may benefit from psychological counseling to help them accept and live with their voice problem.
Yoga Therapy for Dystonia
Those doing yoga exercise benefits movement-disorder like Parkinsons, multiple sclerosis patients, strokes, fibromyalgia and arthritis. The relaxation associated with yoga can be positive for anyone with a movement disorder.

Yoga can help Parkinson’s
Parkinson’s disease is one of the most well-known movement disorders. Parkinson’s is a neurological condition that affects movement. The symptoms include tremors, shaky hands, impaired balance, coordination impairments and poor posture. According to the Parkinson’s disease and Movement Disorder Society, yoga can help control symptoms of the disease. Yoga helps reduce the stiffness and rigidness associated with Parkinson’s due to the stretching involved. In addition, doing yoga can also increase mobility, flexibility and strength in patients with Parkinson’s disease.
Yoga can help Multiple Sclerosis
Multiple sclerosis, more commonly known as MS, is a neurological disorder that causes messages from the brain to your body to slow down or stop. This is because your immune system attacks the myelin that protects nerve cells. MS causes muscle weakness, poor coordination and balance, and memory problems. Yoga has the potential to relax you, which can assist alertness and memory skills. Yoga releases the muscle tension and thus reduces the spasticity.
