How long is clonus normal in babies?
Clonus is a series of involuntary muscle contractions and relaxations. It’s a reflex that’s present in babies because their nervous systems are still developing. You might notice your baby’s foot moving up and down after you flex their foot.
If you’re concerned about your baby’s development or if you notice anything unusual, it’s always a good idea to talk to your pediatrician. They can assess your baby and determine if there are any underlying concerns.
Remember, clonus is a normal part of baby development. Most babies will grow out of it by eight months old. But, if you have any questions, always reach out to your doctor for reassurance.
When does clonus go away?
Physical therapy can be very helpful in treating clonus and muscle spasms. Therapists can teach you exercises that help strengthen and stretch your muscles, which can reduce the frequency and severity of your spasms. Over time, as your muscles get stronger and more flexible, you’ll likely notice a significant improvement in your symptoms.
For people with chronic conditions like multiple sclerosis (MS), meningitis, or stroke, clonus may be a more persistent issue. While these conditions may require long-term treatment, there are still ways to manage clonus and improve your quality of life. For example, medications can be used to relax muscles and reduce spasms. Additionally, adaptive devices and assistive technology can help people with clonus perform daily tasks.
It’s important to remember that everyone’s experience with clonus is unique. If you’re concerned about clonus or muscle spasms, talk to your doctor. They can help you understand the cause of your symptoms and recommend the best treatment options for you.
What is the normal range of ankle clonus?
Now, let’s dive a bit deeper into what this means for ankle clonus. Think of the oscillation period as the time it takes for the ankle to go through one complete cycle of clonus – from contraction to relaxation and back again. So, with an average period of 160-200 milliseconds, your ankle would be completing this cycle about 5 to 6 times every second.
It’s important to remember that these are just average values. The actual frequency and oscillation period of clonus can vary depending on factors like the individual’s age, muscle condition, and the underlying cause of the clonus. If you’re experiencing ankle clonus, it’s always best to consult a healthcare professional to get a proper diagnosis and discuss appropriate treatment options.
What is the duration of clonus?
The duration of clonus can vary depending on the underlying cause and the severity of the condition. In general, clonus lasts for a few seconds, but it can sometimes persist for longer periods, even minutes, in some individuals. Clonus is often triggered by a sudden stretch of the muscle, and it can be exacerbated by fatigue, stress, or changes in body temperature.
The frequency of clonus is typically around 5-8 Hz, and the average period of oscillations of the ankle clonus is approximately 160–200 ms. Interestingly, plantar flexion (pointing the toes downward) comprises 45% of the period and dorsiflexion (pointing the toes upward) 55% of the period, which is a little more than the plantar flexion phase.
Let’s break down the duration of clonus a bit more. The duration of a single cycle of clonus is determined by the time it takes for the muscle to contract and relax. This period is often referred to as the “oscillation period”. The oscillation period is influenced by a number of factors, including the properties of the muscle itself, the strength of the nerve impulse, and the overall health of the nervous system.
In addition to the oscillation period, the overall duration of clonus is also influenced by the number of cycles that occur. This number can vary depending on the severity of the condition and the factors that are triggering the clonus. For example, clonus that is triggered by a sudden stretch may only last for a few cycles, while clonus that is caused by a more serious neurological condition may persist for many cycles.
It’s important to remember that clonus is a symptom, not a diagnosis. If you are experiencing clonus, it is important to see a doctor to determine the underlying cause and receive appropriate treatment. Understanding the duration of clonus can help you communicate your symptoms to your doctor, which can lead to a more accurate diagnosis and treatment plan.
When is clonus abnormal?
Clonus is a series of involuntary muscle contractions and relaxations that resemble spasms. It often occurs in the feet or hands, and is usually associated with a neurological condition. When clonus is sustained for more than 10 beats, it’s a clear sign of an underlying neurological issue. This means it’s not something to ignore. It’s important to note that clonus itself isn’t always abnormal. Sometimes it can occur after strenuous exercise or a sudden change in temperature. However, if you experience sustained clonus, especially if it’s accompanied by other symptoms such as weakness, numbness, or difficulty moving, you should see a doctor to rule out any underlying health concerns.
Sustained clonus can be a symptom of various conditions, including:
Upper motor neuron disorders: These conditions affect the nerve pathways that carry signals from the brain to the muscles.
Spinal cord injury: Damage to the spinal cord can disrupt the communication between the brain and the muscles, leading to clonus.
Multiple sclerosis (MS): This autoimmune disease damages the myelin sheath, which protects nerve fibers. This can lead to a range of symptoms, including clonus.
Cerebral palsy: This condition affects muscle movement and coordination due to brain damage.
If you experience sustained clonus, it’s crucial to get a proper diagnosis from a medical professional. The doctor will likely perform a physical exam and may order tests such as an MRI or electromyography (EMG) to determine the underlying cause. Early diagnosis and treatment are essential to manage any underlying condition and prevent complications.
Can clonus ever be normal?
It’s important to remember that clonus in infants is a complex phenomenon, and it’s best to consult with a medical professional to get a proper diagnosis. While some babies might show signs of clonus as a normal variation, others might display it as an early sign of neurological conditions. A doctor will assess the infant’s overall health and neurological development to determine if the clonus is a cause for concern.
It’s also important to understand that clonus in adults can be caused by a variety of factors, including neurological conditions, medications, and even stress. If you experience clonus, it’s essential to seek medical advice to rule out any underlying health issues.
How to stop ankle clonus?
Sometimes, ankle splints can help to support your ankles and reduce the involuntary movements. It’s always best to talk to your doctor before starting any new supplements, including magnesium. Magnesium might help relax your muscles, but it’s important to get professional advice.
Surgery is a less common option for ankle clonus, usually considered when other treatments haven’t worked. It usually involves carefully removing a small part of the damaged nerve that’s causing the muscle spasms. This is a big decision, so it’s crucial to have a thorough discussion with your doctor about the risks and benefits.
Here’s a little more detail about ankle clonus and surgery:
Ankle clonus is a condition where your ankle repeatedly contracts and relaxes in a rhythmic way, even when your foot is in a relaxed position. It’s often a symptom of an underlying neurological issue. It can be really uncomfortable and disruptive to your daily life.
Surgery is usually considered only as a last resort for ankle clonus. It’s a complex procedure and, like any surgery, it has potential risks and side effects. It’s important to weigh these factors carefully with your doctor to decide if surgery is the right option for you.
Important things to remember:
It’s crucial to talk to your doctor about your ankle clonus and any treatments you might be considering. They can help you understand your options and make informed decisions.
Surgery is generally considered a last resort for ankle clonus, and there are many other treatments that can help.
Your doctor can provide you with the best advice based on your specific situation.
Remember, it’s important to be proactive in managing your health and to seek professional advice when needed.
Is clonus normal in premature babies?
The Babinski sign is a reflex that’s often seen in babies. It’s a normal part of development. To test for the Babinski sign, a doctor will gently stroke the bottom of the baby’s foot. If the baby is less than two years old, their big toe will usually point up and their other toes will fan out. This is a positive Babinski sign.
It’s important to remember that clonus and the Babinski sign can be caused by a variety of things. If you have any concerns about your baby’s health, it’s best to talk to their doctor. They can help determine if your baby’s clonus is normal or if it’s a sign of a more serious problem.
Clonus is a series of involuntary muscle contractions that occur in rapid succession. It can happen in any part of the body, but it’s most common in the ankles and feet. In babies, clonus can be caused by a number of things, including:
Prematurity: Premature babies are more likely to have clonus because their nervous systems are still developing.
Brain injury: A brain injury can also lead to clonus.
Spinal cord injury: A spinal cord injury can also lead to clonus.
Infection: Certain infections can cause clonus.
Medications: Some medications can cause clonus as a side effect.
If your baby has clonus, your doctor will likely do a physical exam and order some tests to determine the cause. They may also recommend physical therapy or other treatments to help manage the clonus.
It’s important to note that clonus can be a serious symptom, so it’s essential to get your baby checked out by a doctor if you notice any signs of it. With prompt diagnosis and treatment, most babies with clonus can go on to live healthy, happy lives.

What is the prognosis of ankle clonus?
Ankle clonus is a neurological sign that can be observed in infants. It refers to a rhythmic, involuntary contraction of the foot muscles when the foot is passively dorsiflexed (bent upwards). While ankle clonus can be a normal finding in newborns, it can also be a sign of underlying neurological problems.
If a baby develops neurological signs other than ankle clonus within the first four months of life, and these signs persist after five months, it’s important to monitor their development closely. This is because these babies may be at higher risk for developing neurological abnormalities.
It’s important to remember that prognosis is a complex topic and depends on the specific underlying cause of the neurological signs.
Here’s what we can say about the possible implications of this type of presentation:
Early identification: The earlier a neurological issue is identified, the better the chances of successful intervention and management.
Close observation: Close observation and regular monitoring by a healthcare professional are crucial to track the child’s progress and adjust treatment plans as needed.
Individualized care: Each child is unique, and their care plan should be tailored to their individual needs and circumstances.
It’s essential to avoid making generalizations or drawing definitive conclusions about a child’s future based solely on the presence of ankle clonus.
Instead, focus on providing early intervention, comprehensive evaluation, and ongoing support for the child. This approach offers the best chance for positive outcomes and helps families navigate the challenges associated with potential neurological concerns.
Remember, the information provided here is not a substitute for professional medical advice. It’s crucial to consult with a qualified healthcare professional for a comprehensive evaluation and personalized guidance.
Is ankle clonus normal?
A Babinski sign is another reflex that can be tested by stroking the bottom of the foot. A normal reflex is for the toes to curl down. If the big toe moves upward and the other toes fan out, this is called a positive Babinski sign, and it’s abnormal. A positive Babinski sign can be a sign of a problem with the nervous system, but it can also be a normal finding in young children.
It’s important to remember that these are just general guidelines. If you have any concerns about your child’s reflexes, it’s always best to talk to their doctor.
Ankle clonus is a rhythmic, involuntary contraction and relaxation of the ankle muscles. It is often caused by a problem with the central nervous system, such as a stroke, brain injury, or multiple sclerosis. It can also be a sign of other conditions, such as meningitis, encephalitis, and certain types of medications.
Ankle clonus is typically tested by having the patient lie on their back with their legs extended. The doctor then quickly and forcefully dorsiflexes (bends the foot upward) the patient’s foot. If the ankle repeatedly clonus (rhythmically flexes and extends), this is considered a positive ankle clonus.
The intensity and duration of ankle clonus can vary depending on the underlying cause. In some cases, it may be only a mild and temporary symptom, while in other cases it can be severe and persistent.
If you are experiencing ankle clonus, it is important to see your doctor to determine the underlying cause and receive appropriate treatment.
What is a sustained ankle clonus?
Sustained ankle clonus is a reflex that can be observed in newborns and adults. It’s a sign that the corticospinal tracts, which are bundles of nerve fibers that connect the brain to the spinal cord, may not be working properly.
Here’s a breakdown:
Clonus: This refers to rhythmic, involuntary muscle contractions. It’s like a series of quick, repetitive twitches.
Ankle clonus: This specifically refers to clonus in the ankle.
Sustained ankle clonus: This means that the clonus continues for a prolonged period, even after the foot is dorsiflexed (bent upward).
The presence of sustained ankle clonus in newborns is significant because it suggests that the corticospinal tracts are not functioning as they should. These tracts are crucial for controlling movement and coordination.
A similar reflex to the plantar response has been described for the hand in term and preterm newborns. This reflex is called the Babinski reflex, and it involves the toes fanning out and the big toe extending upward when the sole of the foot is stroked.
It’s important to understand that not all newborns who exhibit ankle clonus have a serious neurological condition. In some cases, it may be a temporary phenomenon, and the clonus may disappear as the baby grows and develops.
However, if you notice sustained ankle clonus in your newborn, it’s always best to consult a healthcare professional. They can assess the situation and determine if further evaluation is needed. This will help ensure that any underlying issues are detected early and addressed appropriately.
What is clonus of the ankle?
Clonus of the ankle is a reflex that indicates a problem with your nervous system. It happens when your ankle repeatedly moves up and down (dorsiflexion) after a quick and forceful upward movement of your foot.
This simple test helps doctors determine if the problem is in your central nervous system (brain and spinal cord) or your peripheral nervous system (nerves in your arms, legs, hands, and feet).
How is the Clonus test done?
It’s a very easy procedure that doesn’t require any special equipment. Here’s how it works:
1. Relax your leg. Sit comfortably with your leg relaxed and your foot dangling.
2. The doctor will gently move your foot upward. They’ll quickly lift your foot upward, stretching your calf muscles.
3. Observe your ankle movement. If you have clonus, your ankle will continue to move up and down, like a rhythmic beating, even after the doctor stops moving your foot. The number of times your ankle moves is important and is noted by the doctor.
What does clonus mean?
Clonus can be a sign of several medical conditions, including:
Upper motor neuron lesions: These are problems with the nerves that connect the brain to the muscles. These problems can be caused by things like stroke, brain injury, spinal cord injury, or multiple sclerosis.
Spinal cord disorders: Conditions like spinal cord tumors, spinal cord injury, or spinal muscular atrophy can affect the nerves that control muscle movement and lead to clonus.
Certain medications: Some medications, such as certain anticonvulsants or muscle relaxants, can cause clonus as a side effect.
Remember: Clonus is not a diagnosis in itself. It’s a sign that needs to be investigated further to determine the underlying cause. If you experience clonus, it’s important to see a doctor to get a proper diagnosis and treatment.

When Should Ankle Clonus In Babies Stop?
Understanding Ankle Clonus
First things first, let’s get a handle on what ankle clonus even is. Basically, it’s a series of rhythmic, involuntary muscle contractions in your baby’s ankle. You might see their foot bouncing or twitching uncontrollably.
It’s usually a reflex, meaning it’s an automatic response to a particular stimulus, like when you quickly dorsiflex their foot (point their toes upwards).
When Should It Stop?
Here’s the thing: ankle clonus is actually pretty common in newborns and babies. It’s a normal part of their developing nervous system. Usually, it fades away as their brain matures.
The good news is that there’s no specific age when it *has* to stop. Some babies might stop showing clonus within a few weeks of birth, while others might show it for a few months. It’s all about individual development.
When to Worry?
Now, while ankle clonus is often harmless, it’s always wise to keep an eye out for any red flags. If you notice ankle clonus along with other signs like:
Difficulty feeding
Weak muscle tone
Poor reflexes
Excessive fussiness
Problems with movement
Then it’s essential to get in touch with your pediatrician. These symptoms might indicate a more serious neurological condition, and early diagnosis is crucial.
What Can I Do?
If you’re concerned about your baby’s ankle clonus, don’t hesitate to reach out to your doctor. They’re your best resource for getting personalized advice and ensuring your little one is healthy and happy.
FAQs:
Q: How do I check for ankle clonus in my baby?
A: It’s simple. Just gently support your baby’s leg with one hand and quickly point their toes upwards (dorsiflex) with the other hand. If their foot starts to bounce or twitch rhythmically, that’s ankle clonus.
Q: Is ankle clonus a sign of brain damage?
A: Not necessarily. In most cases, ankle clonus is a normal reflex in babies. It’s only a concern if it’s accompanied by other neurological symptoms.
Q: Why does ankle clonus happen?
A: Ankle clonus occurs due to the immature development of the nervous system in babies. As their brain matures, the reflex typically fades away.
Q: What if my baby’s ankle clonus is still present at 6 months?
A: While ankle clonus usually disappears by a few months, it’s not always a cause for worry. However, if your baby is still showing ankle clonus at 6 months, or if it’s accompanied by other concerning symptoms, it’s best to speak to your doctor for further evaluation.
