Myoclonus and other jerky movements form a large heterogeneous group of disorders.
Clinical neurophysiology studies can have an important contribution to support diagnosis …

Myoclonus is a sudden brief (20–250 ms) contraction (positive myoclonus), or a brief and
sudden cessation of tonic muscle (negative myoclonus) inducing a simple jerky movement …

Background Many different movement disorders have similar “jerk‐like” phenomenology
and can be misconstrued as myoclonus. Different types of myoclonus also share similar …

Tremor and myoclonus are very common manifestations of psychogenic movement
disorders (PMD). In this context, recording of movement disorders aims to provide objective …

Functional jerks are among the most common functional movement disorders. The diagnosis
of functional jerks is mainly based on neurologic examination revealing specific positive …

Objective To evaluate the accuracy of clinical phenotyping of myoclonus patients and to
determine differentiating clinical characteristics between cortical (CM), subcortical (SCM) …

Myoclonus is a movement disorder characterized by the occurrence of an involuntary abrupt
muscle contraction causing a sudden unexpected jerk. Many other movement disorders can …

Objective To demonstrate the usefulness of neurophysiological evaluation to distinguish
simple motor tics and functional myoclonus. Methods Careful clinical assessments …

Myoclonus, defined as shock-like involuntary movement, may be physiological or caused by
a very wide variety of hereditary and acquired conditions. Because myoclonus can originate …

Spinal Myoclonus (SM) is characterized by brief and sudden movements caused by the
activation of muscles belonging to adjacent spinal myotomes. Recent reports have indicated …
