Clonus is a set of involuntary and rhythmic muscular contractions and relaxations. Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is, accompanied by spasticity. Unlike small, spontaneous twitches known as fasciculations, clonus causes large motions that are usually initiated by a reflex. Studies have shown clonus beat frequency to range from three to eight Hz on average, and may l

A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus. [1] [2] A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.

The usual rates are 5 to 8 Hz; in any muscle in one patient, the rate tends to remain the same. Like other reflexes induced by stretch, clonus occurs with an appropriate degree of increased muscle tone. Clonus is a rhythmic, oscillating, stretch reflex, the cause of which is not totally known; however, it relates to lesions in upper motor neurons and therefore is generally accompanied by hyperreflexia.
