Myoclonus is defined as sudden, brief, shock-like involuntary movements affecting one or more muscles. The term encompasses a wide range of different physiologic and pathologic processes. When evaluating a patient with myoclonus, the first step is to identify the underlying etiology.

Sleep Medicine Clinics, 2021
Propriospinal myoclonus (PSM) consists of paroxysmal and sudden jerks involving axial flexion trunk and hip muscles, conditioning sudden myoclonias of the trunk and arms/limbs, both spontaneous and triggered by sensory stimulations, emerging in relaxed wakefulness typically during the transition between wake and sleep.

Current Opinion in Neurology, 1995
Genetic studies have suggested homogeneity between the Baltic-type and Mediterranean-type progressive myoclonic epilepsy. Magnetoencephalography was applied to elucidate the mechanism underlying the giant evoked responses in cortical reflex myoclonus. A new concept of negative myoclonus mediated by cortical reflex mechanism was proposed.

Neurophysiology of myoclonus and progressive myoclonus epilepsies
Epileptic Disorders, 2016AbstractThe high temporal resolution of neurophysiological recordings makes them particularly suited to faithfully describing the time course of rapid events such as myoclonus and to precisely measure its time relationship with other related activities.

The diagnosis and treatment of myoclonus pose a particular challenge to the neurologist. Few well-controlled double-blind studies of antimyoclonic agents have been performed, and clinical rating of the effectiveness of treatment has been primarily descriptive. As a result, therapy is often empiric. This article reviews the author's approach to treating

Myoclonus-Dystonia/Essential Myoclonus☆
2010Myoclonus-dystonia (M-D, formerly known as ‘Hereditary essential myoclonus’) is a rare movement disorder characterized by myoclonic jerks and dystonic movements or postures. M-D has an autosomal dominant inheritance with reduced penetrance because of maternal imprinting and is caused by mutations in the ϵ-sarcoglycan gene (SGCE) on chromosome 7q21.

Myoclonus in childhood may be a primary condition, or it may be associated with a number of identifiable conditions. Successful therapy is dependent on diagnosis of underlying conditions and subsequent choice of appropriate drugs.

Myoclonus can be classified as physiologic, essential, epileptic, and symptomatic. Animal models of myoclonus include DDT and posthypoxic myoclonus in the rat. 5-Hydrotryptophan, clonazepam, and valproic acid suppress myoclonus induced by posthypoxia.

A 5-year-old boy is reported with spinal myoclonus caused by cervical astrocytoma due to neurofibromatosis. The essential clinical and electromyographical signs of spinal myoclonus are the following: (1) Continuous rhythmical appearance in muscles innervated by the affected segments of the spinal cord. (2) Synchronous myoclonus in muscles innervated by
