Tremor may be confused with rhythmic myoclonus (incorrectly termed cortical tremor), which is typically characterised by brief muscle twitches, confined to one limb or to adjacent body regions, associated with spike-wave complexes on the electroencephalogram (EEG) or spinal lesions. It is differentiated from other involuntary movement disorders, such as chorea, athetosis, ballism, tics, and myoclonus, by its repetitive, stereotyped movements of a regular amplitude and frequency. It is defined as an involuntary, approximately rhythmic, and roughly sinusoidal movement of one or more body parts. Tremor is one of the most common involuntary movement disorders seen in clinical practice. Evidence supporting various strategies used in the differentiation is then presented, followed by a review of formal guidelines or recommendations when they exist.

This article focuses on a practical approach to these different forms of tremor and how to distinguish them clinically. Essential tremor and the tremor of Parkinson’s disease are the most common tremors encountered in clinical practice. The causes of tremor are heterogeneous and it can present alone (for example, essential tremor) or as a part of a neurological syndrome (for example, multiple sclerosis). In addition to the detailed history, the differential diagnosis is mainly clinical based on the distinction at rest, postural and intention, activation condition, frequency, and topographical distribution. If your problems are mainly swallowing related, your treatment team will discuss with you the treatment options available.Tremor is one of the most common involuntary movement disorders seen in clinical practice. Lee Silverman Voice Treatment is an evidence-based voice therapy program for Parkinson’s disease. This can also help make swallowing safer. When appropriate, vocal fold atrophy or vocal cord immobility can be treated with in-office vocal fold injections designed to increase the volume of the vocal cords and help them come together better. An EMG is used to measure the electrical activity of your vocal muscles. Our experts often use specialized electromyography EMG equipment to perform these vocal cord muscle injections.

Spasmodic dysphonia and tremor (when appropriate) can be treated in the office setting with botulinum toxin to chemically weaken the muscles that are abnormally firing. If your symptoms are mainly voice related, your treatment team will recommend treatments aimed at improving your vocal quality, projection and effort required to speak: Voice and Swallowing Impact from Neurologic Disorders Treatment Rarer neurologic disorders that can dramatically affect voice and swallowing include:Īmyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) Stroke: Changes following a stroke range from minor problems from which a patient can fully recover all the way to profound voice and swallowing changes (including complete loss of some muscles that control the vocal cords and swallowing), depending on the areas of the brain and brainstem that were affected. Patients may experience an inability to project and be heard easily by others. Many patients notice that their voice becomes weak and tremulous. Parkinson’s disease: This neurologic disease is characterized by tremor and muscle weakness/slowness, both of which can affect voice and swallowing. Tremor may occur in the muscles of the throat or vocal cords alone but often is part of a systemic tremor that affects the neck, hands, arms or legs. Tremor: Tremor of the throat or vocal cords can cause changes that make the voice sound “shaky” or unsteady, and it may overlap with the diagnosis of spasmodic dysphonia. Patients often report that their voice is worse when speaking on the telephone or when they are anxious or nervous and more normal when laughing or singing. It gives patients either a strained or breathy voice, depending on which vocal cord muscles are dominantly affected, and may greatly affect the patient’s ability to communicate with others.

It is caused by abnormal firing of different muscles that move the vocal cords during speech. Spasmodic dysphonia: This disorder primarily affects the voice and not swallowing function. Occasionally, a voice or swallowing problem can be the first or only symptom of a neurologic condition.Ĭommon neurologic disorders affecting voice include: Often, patients already have a diagnosis from a neurologist and are referred to a laryngologist to be evaluated for interventions that can help with their voice or swallowing. What impact do neurologic disorders have on voice and swallowing function?Ī number of different neurologic disorders can cause changes in voice and/or swallowing function.
