[15], Surface electromyography (sEMG) has been considered as a diagnosis tool for MTD. Muscle tension dysphonia involves problems with the muscles around the vocal cords and in the throat. [1] It is important to consider other dysphonias in the differential diagnosis. Muscle tension dysphonia (MTD) was originally coined in 1983 by Morrison and describes a dysphonia caused by increased muscle tension of the muscles surrounding the voice box: the laryngeal and paralaryngeal muscles. Muscle tension dysphonia (MTD) is a condition characterized by changes in voice quality in the absence of vocal fold or laryngeal pathology. Neck that is tender or sore to the touch 7. This imbalance can be seen without any anatomical abnormality (primary MTD) or in the presence of an anatomical abnormality (secondary MTD). Muscle tension dysphonia (MTD) occurs when the muscles around the voice box are constricted during speech production. Muscle Tension Dysphonia Neurologic Voice disorders Paradoxical Vocal Fold Motion Disorder (PVFMD) / Exercise Induced Laryngeal Obstruction (EILO) Psychogenic Voice Disorders Recurrent respiratory papillomatosis (RRP) Reflux Laryngitis Reinke’s edema Spasmodic Dysphonia Vocal Cord Granuloma Vocal Cord Scarring Vocal Fold Atrophy Feeling the need to clear the throat often 9. A multidisciplinary team including otolaryngologists and speech language pathologists is useful for the evaluation and diagnosis of MTD. Her clinical experience enables her to provide comprehensive one-on-one, group and school program interventions. PVFMD is a breathing disorder that is caused by the abnormal movement of the vocal folds during breathing. It’s often overlooked and left untreated. MTD may occur on its own, called primary MTD - or as a result of another underlying disorder, called secondary MTD. [7] The goal of voice therapy is to encourage proper vocal used and decrease the tension of the laryngeal muscles. [15] When assessing the vocal cords, the most common finding in MTD is a posterior glottic gap. Among many of the struggles the Boys get candid about in their story, it was revealed that group member, Brian Littrell has been suffering from Muscle Tension Dysphonia. Palpation is a key exam maneuver when evaluating MTD. [3], Voice therapy is commonly used in the treatment of MTD. Muscle Tension Dysphonia (MTD) is the most common voice disorder. They can also happen as the result of a stroke. [3] Additionally incorrect use of the voice can cause increased tension and lead to MTD. Husky, hoarse, breathy and/or rough voice 2. This tension prevents the voice from working efficiently. [3], The voice quality in MTD can be described as breathy and can also sound harsh. Voice therapy offered by a Speech Pathologist is the preferred management option for the treatment of muscle tension dysphonia. Complete loss of the voice is possible. Muscle tension dysphonia (MTD) is the technical term for stressful or strenuous overuse of the voice, resulting in vocal dysfunction. not speaking). [8] It is caused by increased tension of the laryngeal muscles secondary to personality traits such as anxiety or life factors such as increased stress. Muscle tension dysphonia is a condition wherein the feel or the sound in your voice has changed and the primary cause is the tension in the muscle near your voice box. Muscle tension dysphonia, or voice strain caused by muscle tightness, can occur even when there is no damage to your vocal cords (also known as vocal folds). Laryngeal muscle tension may be one of the underlying etiologies in patients with functional dysphagia Muscle Tension Dysphagia (MTDg) defined: patients with idiopathic dysphagia complaints, a “normal” VFSS, and evidence of laryngeal hyperfunction on laryngoscopy PRIMARY: tension alone SECONDARY: tension + LHR and/or NLI Most of the time, it is due to extra effort that one puts into voice to try to work around another vocal problem. [3] Primary MTD makes up a significant proportion (as high as 40%) of patients seen for voice complaints. [7] Multiple factors cause the muscles of the larynx to become tense. In a previous post I discussed the production of the voice by the coordination of three different systems (see post here).These include the breath, the vocal folds, and the vocal tract (everything above the vocal folds including the throat, nose, and mouth). Tightness and even muscle aches in the throat 3. A tight ‘choking’ sensation when using voice, Increase fatigue and effort associated with increased voice use, Irritants such as upper respiratory tract infection, passive smoking, acid reflux. It involves putting extra effort into a vocal task that perhaps is not necessary or required to make sound. It is associated with excessive muscular tension or inappropriate use of the muscles around and above the vocal cords. What are the things that may trigger this kind of disorder? [13] This index is made up of many measurements of the voice include voice frequency measurements (high and low), maximum phonation time (MPT), and jitter (frequency instability). [15] Examples of voice therapy include voice exercises to help increase glottic closure, vocal hygiene, manual laryngeal therapy, respiratory exercises, nasal exercises and frequency modulation amongst other techniques. In addition, the medical professional may recommend that the patient see a speech therapist . These spasms interrupt normal voice (dysphonia) in “abrupt spurts” with a strained, strangled voice; with breathy, soundless voice; or with a mixture of both. Psychogenic voice disorders Psychogenic voice disorders have no apparent physical cause. Muscle tension dysphonia (MTD) is a condition of extra vocal work and strain. Muscle Tension Dysphonia – I’ve lost my Voice! [4], MTD has been known by other names including muscle misuse dysphonia, hyperfunctional dysphonia, and hyperkinetic dysphonia among others. Muscle tension dysphonia has several signs and symptoms, including: 1. When this happens it is usually referred to as a Muscle Tension Dysphonia or MTD. Purpose of review: The purpose of this review is to summarize current evidence regarding treatment for muscle tension dysphonia (MTD) and to present recent advances in evaluation and management. [3] There is increased muscle activity in MTD due to personal temperament, increased vocal use, and underlying medical or physical causes. Beside above, how is dysphonia treated? Botox makes the muscles in your larynx weaker. [3] It also has been found that MTD can occur in postmenopausal women due to decreased hormone levels which lead to swelling of the laryngeal tissues and eventual atrophy. Some possible causes include: An Ear, Nose and Throat doctor will examine your vocal cord function to determine diagnosis. It may be effortful to produce and discomfort or even pain can develop, particularly with heavy voice use or when speaking against background noise. MTD is a pattern of muscle use that can develop during laryngitis and remain even after swelling of the vocal cords has gone. MTD is a change in the sound or the feel of the voice due to excessive muscle tension in and around the voice box. It was a bit of a joke back in April at the start of lockdown when I lost my voice. Tips and tricks on how to manage and heal from muscle tension dysphonia (MTD) Tips for speaking and for singing. [15] Stroboscopy allows the visualization of vocal cord movement, which vibrate too quickly for human eye to perceive. Reinke's edema risk factors and causes Women are more likely than men to get Spasmodic dysphonia (SD) is a voice disorder resulting from involuntary movements (or spasms) of the voice box muscles. [16], In secondary MTD, the underlying medical cause should be addressed. The muscle tension is preventing your voice to work properly. Muscle Tension Dysphonia (MTD) Treating Pain, Strain, and Changes in Voice Function . [3], Primary MTD has no underlying medical or physical cause and no known psychogenic or neurologic cause. MTD is … [2], The pathophysiology of MTD is multifactorial. It is likely that more than one factor contributes to changes in the vocal mechanism leading to Muscle Tension Dysphonia. [2] Larynogopharyngeal reflux, a process that is similar to GERD, can bring stomach acid into the larynx. Muscle tension dysphonia (MTD) was originally coined in 1983 by Morrison[2] and describes a dysphonia caused by increased muscle tension of the muscles surrounding the voice box: the laryngeal and paralaryngeal muscles. Treatments for Spasmodic Dysphonia Your doctor may inject botulinum toxin, or Botox, into one or both vocal folds. [2] MTD can be distinguished for another similar dysphonia, adductor spasmodic dysphonia, by differences in voice characteristics. Recognition of the role of extralaryngeal tension is helpful in ensuring proper diagnosis and selection of appropriate treatment. Muscle Tension Dysphonia may be characterised by: The cause of Muscle Tension Dysphonia is not completely understood. This, in turn, creates an imbalance that alters the vibration of the vocal folds. It allows for the diagnosis of dysphonia caused by many different etiologies and can be confirmed by history, physical exam, laryngoscopy and videostroboscopy, a technique that allows for the direct visualization of the larynx, vocal cords, and vocal cord motion. This can provoke the larynx to tense to prevent the aspiration of the acid. The term “muscle tension dysphonia” is a general term for an imbalance in the coordination of the muscles and breathing patterns needed to create voice. [12] In MTD, all vocal tasks (vowels, singing, etc) are difficult for the patient while in adductor spasmodic dysphonia, some vocal tasks are difficult while others are unaffected. Muscle tension dysphonia is caused by abnormal contractions of the muscles of the voice box that control the voice. It's what's known as a “functional dysphonia,” referring to when a person develops a pattern of muscle use because of irritants, laryngitis, or stress, among other conditions. Voice that sounds strained, pressed, squeezed, tight or tense. This is a condition that causes the sound and feel of his voice to change due to extreme muscle tension in and around the voice box. Residual infections should be treated. [6] To make the exam more objective, various scales have developed to help standardize the process. A personalised treatment plan will depend on the severity of the dysphonia and the cause. I think it was the combination of a virus and the whole stress of the lockdown been announced. [16] The results of studies using sEMG in MTD is currently mixed. functional type), and MTD as a result of personality and/or psychological factors (i.e. Jenna Butterworth is a Speech Pathologist who sees both children and adults. [9], Secondary MTD is caused by an underlying medical or physical reason. Over time, untreated MTD results in worsening of symptoms, including loss of vocal range and pain when singing/performing. It also limits you to be effective in oral communication. She has experience from a spectrum of clinical environments including teaching hospitals, community and private practice. [12] There are objective parameters that help characterize the degree of dysphonia such as the Dysphonia Severity Index. This changes the position of the larynx and affects the cartilaginous structures within the larynx leading to abnormal phonation. This section will discuss primary MTD. [3], MTD is more commonly diagnosed in women,[5][3] the middle aged,[2] and individuals who have high levels of stress. In the case of secondary MTD, the muscle tension is thought to be the body’s natural compensatory process to adjust for the vocal injury. Massage in the area right below the floor of the mouth. Feeling a lump in the throat In most cases, MTD produces these vocal symptoms without any actual physical damage. [3] Vocal fold lesions such as a vocal fold nodule or other changes in the vocal fold mucosa can lead to increased tension in the larynx and cause dysphonia. Move up higher on both sides under the chin (below jaw) pinching the bottom of the tongue. Neurologic voice disorders occur as part of an underlying neurologic condition such as Parkinson's disease, multiple sclerosis, myasthenia gravis, or ALS. Psychological difficulties usually underlie this category of voice disorders. Some studies demonstrate increased EMG levels in MTD[17][18] while others do not demonstrate a difference in EMG between individuals with MTD and individuals without MTD. Excessive activity of the extralaryngeal muscles affects laryngeal function and contributes to a spectrum of interrelated symptoms and syndromes including muscle tension dysphonia and spasmodic dysphonia. What are the symptoms of MTD? Muscle tension dysphonia may make the voice sound weak, hoarse, breathy, strained, tense or rough. Trauma – such as injury, chemical exposure or an emotionally traumatic event. The vocal folds are located on top of the airway and typically open wide for breathing to allow air to pass through, and the vocal folds close together for talking in order to allow the vocal folds to vibrate to make sound. organic type), MTD stemming from vocal use (i.e. Muscle tension dysphonia is a condition characterized by hoarseness or a strained, rough quality of the voice. [16] sEMG can measure the muscle units of the muscles of the larynx to deduce if there is increased activity which means they are more tense. These disorders can affect the strength of the muscles of the voice box, and impact the control of the voice. For example, Muscle Tension Dysphonia (MTD) has been found to be a result of many different causes including the following: MTD in the presence of an organic pathology (i.e. Jenna is committed to providing evidence-based interventions for children and adults alike, tailoring therapy to each client’s individual needs. [15], Surgery may be used as a treatment when there is a vocal lesion such as nodule or polyp that is causing the MTD. [1] MTD can be broken in two groups: primary and secondary. [2] Patients may complain that their voice sounds abnormal as well as needing to strain to produce sound, and having increased dysphonia with increased vocalization.[1]. [3], "Videostroboscopy of Human Vocal Fold Paralysis", "The Assessment Methods of Laryngeal Muscle Activity in Muscle Tension Dysphonia: A Review", "Differential diagnosis of muscle tension dysphonia and spasmodic dysphonia", "Vocal Acoustic Analysis – Jitter, Shimmer and HNR Parameters", https://en.wikipedia.org/w/index.php?title=Muscle_tension_dysphonia&oldid=994194090, Creative Commons Attribution-ShareAlike License, Otolaryngology, Speech Language Pathology, changes in voice, hoarse voice, breathy voice, This page was last edited on 14 December 2020, at 15:17. MTD is a unifying diagnosis for a previously poorly categorized disease process. [3] Older men can also develop MTD as their vocal cords thin as they age. psychogenic type). What is Muscle Tension Dysphonia (MTD)? Primary MTD occurs without an underlying organic cause while secondary MTD occur due to an underlying organic source. When the vocal cords are impacted by the swelling, they cannot vibrate in the usual way. [3] Post infectious MTD is also possible. Muscle tension dysphonia is a pattern of muscle use that can develop during laryngitis and remain even after swelling of the vocal cords has gone. Swelling in this area is called Reinke's edema. Jenna creates and sources a wide variety of tools and resources for clients and families to use in order to maximize communication potential. The onset of Muscle Tension Dysphonia can be very subtle. [1] It also more often seen in those who use their voice often such as singers and teachers. Symptoms may become progressively worse with use and improve with rest (i.e. MTD occurs when the muscles of the voice box strain or become tense. Undergoing speech therapy can address the vocal habits that helped to develop the dysphonia initially, and help retrain the individual to make use of the vocal cords in a manner that will minimize … Because of the increased muscle tension of the paralaryngeal and laryngeal muscles, the larynx will be elevated on palpation. Muscle tension dysphonia (MTD) is a condition of hoarseness or other symptoms related to voice production, which occurs as a result of inappropriate use of the muscles around the larynx during speech or singing. Sudden breaks or fading of the voice 6. Muscle Tension Dysphonia Muscle tension dysphonia is hoarseness or other changes in the sound or feel of your voice resulting from excessive muscle tension in and around the voice box. Therapy may include voice exercises and strategies for effective voice use and reduction of muscle tension. excessive muscular tension or inappropriate use of the muscles around and above the vocal cords For example during an episode of laryngitis, the muscles of the larynx tense secondary to the inflammation and residual tension can remaining following the resolution of the illness. A person may work very hard to get the voice out or use too much “muscle tension,” sometimes without even noticing it. Muscle tension dysphonia is often found in those who require to use their voice a lot at work, such as teachers, singers and other professions where there is a high demand for voice use throughout the day. Filed Under: Adult Speech Therapy Tagged With: Problems communicating, Speech Disorders, Treatment, Voice. That means the voice will sound different. It allows for the diagnosis of dysphonia caused by many different etiologies and can be confirmed by history, physical exam, laryngoscopyand videostroboscopy, a technique that allows for the direct visualiz… The voice can sound strained, raspy or very soft. Background and purpose: Muscle tension dysphonia (MTD), a common voice disorder that is not commonly referred for physical therapy intervention, is characterized by excessive muscle recruitment, resulting in incorrect vibratory patterns of vocal folds and an alteration in voice production. Loss of vocal range when singing 8. Strained or tight voice 4. [3] There is little utility to surgery in primary MTD. The non-muscle part of the vocal cord, sometimes called the vocal fold, right under its surface, is called Reinke's space. [3] Individual with high vocal use like teachers, singers, and others professions with high vocal expectations can also develop MTD. [3][6] Voice production requires the coordination of multiple muscles and other structures in the larynx. [13][14], Videostroboscopy is the use of a camera to see the larynx and vocal cords. [3] MTD is a unifying diagnosis for a previously poorly categorized disease process. It occurs when a person habitually uses a dysfunctional muscular pattern to produce voice … [10][11], The voice in MTD has been described as hoarse and breathy. Muscle tension dysphonia is a functional disorder, or one in where there is nothing structurally wrong with the voice. People with muscle tension dysphonia have muscles that do not function properly, causing poor sound, discomfort, or a sensation of increased effort when speaking. More rarely, it can occur all by itself. [2] Other findings include increased movement of the vocal folds towards one another, and changes in the angles of the vocal fold openings. If acid reflux has contributed to the development of Muscle Tension Dysphonia, your GP or ENT doctor can advise you about the appropriate course of treatment. Weak or airy voice 5. 10 TIPS FOR MUSCLE TENSION DYSPHONIA TREATMENT: How to overcome MTD and become a success story.

Muscle Tension Dysphonia is vocal hoarseness that is not due to changes to the tissue of the vocal cords. [3] Laryngopharyngeal reflux is treated similarly to GERD with diet and lifestyle adjustments and consideration for a proton pump inhibitor. When the vocal folds close during breathing, instead of open, this blocks the flow of air and causes the patient to feel a severe sensation of trouble breathing.
