Ankle Clonus Causes
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
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

My eight year old seems to have clonus reaction in ankle when sitting with her heels raised. Full neuro exam normal. What can the cause be?
Possible causes for bilateral ankle clonus if spine and brain MRI are normal? Clonus is more prominent on the left side. Can clonus ever be bening?
I have bilateral ankle clonus. Spine MRI was normal. Seeing a neurologist soon. Could MS-disease cause this by affeting the brain instead of spine?
Clonus: Clonus is a sign that suggests the pathway that regulates muscle contraction was disrupted at some time. It is possible that changes in the brain, not the spine, caused this. But consider this- some people are born this way, and it does not mean that you will eventually be found to have MS. If you had clonus in one ankle, maybe I would think otherwise. ...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.
It is usually sign of neurological disorder as body normally prevents such contractions from occuring. ...Read more
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
Maybe, maybe not: If I find this in any patient over 2 years of age I am concerned. A more thorough evaluation would be needed for such a patient to rule out other issues. ...Read more

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

I took my 3 year old son to the Doctor and found that he had 3-4 beats of clonus in his Left ankle? What could this mean? Should I be worried?
Hyperreflexia: Or overactive tendon reflexes suggests injury to brain or spinal cord. This could be from inflammation like infection, electolyte imbalance, tumor or other lesion. Kids tend to have active ankle reflexes, and several beats of clonus in the ankle is a common finding but asymmetry or persistent clonus needs investigation. It is very common in mild cerebral palsy. Symptoms and developement are clue ...Read more
28 months boy have 4-5 beats ankle clonus in both side since newborn, without other symptoms. He have a good milestone, he can walking-running normally.
The significance of: Ankle clonus in infancy is not reliably known and relates to the number of beats (>10 seemingly important) and persistence at advancing age. The fact that your son has reached developmental milestones normally is very important. I would, however, have your son followed by a good neurologist as there are possible issues down the road. Good wishes:) ...Read more
