Clonus In Infants
Medications, PT: Clonus is over-active reflexes. This can occur after strokes as well as in some other neurological conditions. Occasionally a person will have clonus without any neurological condition. Options include avoiding positions that trigger the clonus; persistent physical therapy after a stroke to help muscle retraining; muscle relaxant medications such as baclofen; and possibly Botox injections. ...Read more
Cerebral palsy: Ivh occurs in prematures, then resolves. Pvl is the result of changes in the brain due to prematurity. Cerebral palsy is a clinical diagnosis which includes spasticity and the ability to elicit clonus. This is often the result of events associated with prematurity. Clonus is a clinical finding that can be seen in normal children, but is more common in children with cerebral palsy. ...Read more
Treppe is a staircase effect by stimulating the muscle at a variable frequency like in a twitch but in treppe it is increasing in a step wise fashion so each time more muscles are recruited in treppe. Not seen in clonus and in tetanus
treppe generally caused by serotonin toxicity
clonus contraction and relaxation of muscle
tetanus is a chronic spasm of a muscle due to bacilus tetanus ...Read more
Spasms & relaxation: Ankle clonus is a series of abnormal reflex movements of the foot, induced by bending the foot upward at the ankle, causing alternate contraction and relaxation of the calf muscle. This can be present in stroke patients, spinal cord injury, and multiple sclerosis. If this is indeed present, talk to your doctor about getting a neurology referral. ...Read more
Ankle clonus is a movement disorder characterised by involuntary waves of muscle contractions in the ankle that occur in responce to streching the muscle in and around the ankle.

Developed nonsustained ankle clonus unilateral. 2 years ago had a neuro exam and this was not present. Is developing it a bad sign?
Sometimes it means something. Non sustained clonus sometimes does not hold up from exam to exam- some people are not good at detecting this.
Clonus of any kind should indicate something happening in the spinal cord or the brain. If you have it on one side, it should be the brain. Sometimes the cause is not found however.
If it was found in a new exam, a work up will be planned. ...Read more
I heard that immature myelin in toddlers can cause mild ankle clonus, is it true? When does the myelin will get mature?
Maturation: The nervous system matures from top down and inside to outside. Ankle clonus is normal in infants until they begin to walk, which the maturation allows. Persistence after 15-18 mo would be a problem. They first gain a wide grasp with fingers like pincers, but fine motor control of the individual fingers will not come in until well into school age. ...Read more

Unilateral hoffman's sign and on the same side have non sustained ankle clonus. What's the cause of this?
Poss c-spine prob: Hoffman's sign is used by clinicians when there is a suspicion of cervical spine pathology possibly pressing on the spinal cord. The sign is more accurate when present bilaterally but can be seen when unilateral. It has also been reported in hyperthyroidism and anxiety states. I hope this helps. Good luck and well wishes. ...Read more
So my son walking (13 months) is still a toddler? I may have from time to time ankle clonus (bits 1-2)? Yes or not?
22 months Boy have ankle clonus since he 3 weeks old. He have a normal milestone&posture. Could a normal child have a clonus for the rest in his life?
Nl devel reassuring: It is very reassuring that your child's development has been very normal in spite of ankle clonus. It is not uncommon to see several beats of anke clonus in healthy children and for children to tiptoe with walking for the first few years, but continuous clonus is unusual and subtle signs of muscle tightness may show up in the future. Hopefully not. ...Read more
Significance: Clonus is usually associated with an upper motor neuron problem and can be seen with spasticity. Real question is the cause, and how to manage the underlying problem. We do have anti-spasticity meds to help, and Botox might be an answer, but let's not put the cart before the horse. See a neurologist and get this diagnosed. ...Read more

My 24 months son have ankle clonus in both sides since newborn. Mostly clonus occured less than 5 beats, he has a good milestone. Is it normal?
I have had 5-6 months of clonus which came on suddenly. I have had spinal surgery, multiple tests from a neurologist which were all negative.?
Hard to say: Clonus is usually a sign of spasticity. Spasticity is usually seen from some abnormality of the upper motor nervous system which includes the brain, the cervical spine, and the thoracic spine. There are many possibilities from stroke, to intraop spinal injury, transverse myelitis, spinal cord infarction just to name a few. A good neurologist should be able to get to the bottom of it. ...Read more
