The durations of clonus burst were found longer than the durations of Soleus medium-latency reflex (MLR). There is a similarity in their nature, although the speed and cause of the stretch of triceps surae differ in the MLR and the clonus, and there is a sufficient period of time for group II afferents and for other spinal mechanisms to be involved in the clonus, together with Ia afferents.

Clonus sensitivity to resetting was studied by evoking a soleus H reflex at different time intervals between two successive clonic beats. The relationship between the interval separating the H reflex from the preceding beat and the inter-beat interval in which the H reflex was delivered was used to calculate the resetting index. Inputsotherthanthoseinducedbystretch causeclonus; examplesofcutaneou3 inputs causing it are given. The following facts are known about clonus. The usual rates are 5 to 8 Hz; in any muscle in one patient, the rate tends to remain the same.

University of Wisconsin School of Medicine and Public Health.Video 16/19 Clonus is a self-sustained, oscillating stretch reflex induced when the clinician briskly stretches a hyperreflexic muscle and then continues to apply stretching force to that muscle. Each time the muscle relaxes from the previous reflex contraction, the applied stretching force renews the reflex, setting up a rhythmic series of muscle contractions that continue as long as the tension is applied. 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 Clonus is a reflex typically caused by sudden, passive stretch of a muscle. For example, when you lift your leg and place your foot back on the ground, the slight upwards stretch of the ankle can trigger clonus.
