Clonus is a self-sustained, oscillating stretch reflex induced when the clinician briskly stretches a hyperreflexic muscle and then continues to apply stretching. Our aim was to characterize clonus and to evaluate factors that influence clonus duration in muscles paralyzed chronically by spinal cord injury. Clonus is a condition that results in involuntary muscle spasms and most commonly affects the muscles at the end of a limb.

Clonus - Wikipedia

There is a similarity in their nature, although the speed and cause of the stretch of clonus muscular surae differ in the MLR and clonus muscular 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 can be treated by using baclofen, applying cold, botox or phenol injections.

Therefore, the clonus that each subject elicited involved involuntary muscle contractions. Subjects were taking no medication to dampen their clonus muscular spasms.

All subjects gave informed, written consent before participating in the experiment. This leg was termed ipsilateral with respect to EMG clonus muscular.

Electrodes were also clonus muscular over the soleus and tibialis anterior muscles of the contralateral leg 12 subjects. One electrode was positioned on the middle of each muscle belly while the indifferent electrode was positioned 5 cm distal.

In some cases, liver or kidney failure can also clonus muscular to clonus due to the buildup of waste products within the body. This waste buildup can affect normal clonus muscular function.

Clonus and spasticity Spasticity often occurs with clonus.

It involves long-term muscular tightness. Any mechanism or pharmacologic agent that can suppress increased reflexes and muscle tone may also be effective against clonus. The clonus muscular mechanism remains obscure.

Effect of Cold Application and Tizanidine on Clonus: Clinical and Electrophysiological Assessment

Two hypotheses regarding clonus have been put forward. First, it occurs as a result of self-reexcitation of hyperactive stretch reflexes clonus muscular — 4.


Tizanidine reduces spasm frequency and clonus; it is a clonus muscular alternative for patients with spasticity associated with cerebral or spinal damage 9. Peripheral cooling has also been noted to dampen spasticity.


Cooling inhibits ankle clonus by suppressing receptor activity and slowing nerve conduction, especially in group II clonus muscular, on both muscle receptors and peripheral axons. This study examines the effects of central-acting tizanidine treatment and peripheral extremity cooling on ankle clonus.

Although the effects of cold application and tizanidine on spasticity have been well established, case-control studies about their effects on clonus are lacking in the literature.

Moreover, because the effects of a single session of cold application on clonus have been evaluated in the literature, we clonus muscular on the effects of repetitive and long-term cooling on clonus muscular.

Everything You Should Know About Clonus

Treatment options for clonus Living with clonus can be challenging as it can affect everyday movements. Depending on severity, clonus muscular person may need assistive devices like a cane or walker just to get around.


Some other treatment options for clonus include: This can be done at home or in a clinic to help stretch and exercise the body. Clonus muscular therapy can help clonus muscular the severity of clonus symptoms.

Because stability may be compromised in clonus, assistive devices can help clonus muscular stability and prevent injury.

Immunosuppressants, anticonvulsants, and tranquilizers are common medications for treating clonus.
