Article Excerpts about Myoclonus
Myoclonus is a
term that refers to brief, involuntary twitching of a muscle or a group of
muscles. It describes a symptom and, generally, is not a diagnosis of a
disease.
(Source: excerpt from NINDS Myoclonus Information Page: NINDS)
Myoclonus describes a symptom and generally is not a diagnosis of a
disease. It refers to sudden, involuntary jerking of a muscle or group of
muscles. Myoclonic twitches or jerks usually are caused by sudden muscle
contractions, called positive myoclonus, or by muscle relaxation, called
negative myoclonus. Myoclonic jerks may occur alone or in sequence, in a
pattern or without pattern. They may occur infrequently or many times each
minute. Myoclonus sometimes occurs in response to an external event or
when a person attempts to make a movement. The twitching cannot be
controlled by the person experiencing it. (Source: excerpt from Myoclonus Fact Sheet: NINDS)

Definitions of Myoclonus:
Myoclonus: One or a series of shocklike contractions of a group of muscles, of variable regularity, synchrony, and symmetry, generally due to a central nervous system lesion. [myo- + G. klonos, tumult]
Source: Stedman's Medical Spellchecker, © 2006 Lippincott Williams & Wilkins. All rights reserved.
Involuntary shock-like contractions, irregular in rhythm and amplitude, followed by relaxation, of a muscle or a group of muscles. This condition may be a feature of some CENTRAL NERVOUS SYSTEMS DISEASES (e.g., EPILEPSY, MYOCLONIC). Nocturnal myoclonus may represent a normal physiologic event or occur as the principal feature of the NOCTURNAL MYOCLONUS SYNDROME. (From Adams et al., Principles of Neurology, 6th ed, pp102-3).

A clonic spasm of a muscle or muscle group

Shock-like contraction of a portion of a muscle, an entire muscle, or a group of muscles; may be part of a disease process or a normal physiological response.

Myoclonus is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Myoclonus, or a subtype of Myoclonus,
affects less than 200,000 people in the US population.
