When you hold your little one, or when you hold their arms or legs, have you ever felt that their body is very stiff and difficult to bend? Sometimes babies' muscles can be unnecessarily stiff. Today we are going to talk about this condition, which is called Hypertonia . Don't worry, being aware of this is the first step.
What is Hypertonia?
Simply put, hypertonia is excessive muscle tension. It's like a piece of wood being stuck instead of a rubber band. Children with this condition have very stiff arms, legs, and necks, making it difficult to move them.
We all have some tension/resistance in our muscles. This is what we call muscle tone . Just hold your biceps in your hand while you're standing. That's the tightness you feel. This muscle tone is what helps us sit up straight, maintain our balance, and keep our senses working properly.
So, when this muscle tone becomes too high, that is, when hypertonia occurs, the movements are very mechanical, like a robot. Because the muscles cannot relax, the body's flexibility is very low. Such babies have difficulty maintaining balance, walking, reaching and picking up things. Sometimes they even need help eating.
What are the types of Hypertonia?
There are two main types of hypertonia. Doctors diagnose this by repeatedly bending a baby's arm or leg at different speeds and in different directions.
- Spastic hypertonia or spasticity: This is when reflexes and muscle spasms increase with movement. Imagine a baby's arm stiffening and twitching as it tries to move.
- Dystonic hypertonia or rigidity: In this, the stiffness of the muscles does not change with movement. It just seems to be constantly tight.
Who does this condition affect? How common is it?
Hypertonia, a condition that affects both infants and adults, can occur after an injury to our central nervous system – the brain and spinal cord. Sometimes it can occur after an accident, or it can be a sign of a congenital condition. It is usually diagnosed before a child is two years old.
It's hard to say exactly how common this is, because hypertonia can also be a symptom of other conditions. But it's not as common as hypotonia – muscle weakness – which affects a baby's motor skills .
How does Hypertonia affect a baby's body?
When your baby has hypertonia , it can be difficult to move their limbs. What happens is that there is a problem with the communication between the brain, nerves, and muscles. The muscles don't know when to contract or relax properly. Think of it like a broken traffic light. There's no signal for cars to stop or go. Similarly, because the baby's muscles are tight, it can be difficult to walk, and they can lose their balance and fall. Because the body doesn't respond quickly enough to help them regain their balance.
What are the symptoms of Hypertonia?
The symptoms of hypertonia are caused by muscles becoming too tight. These symptoms can vary from person to person. Also, the severity of the symptoms varies depending on the location of the damage to the brain or spinal cord.
These are the common symptoms:
- The range of motion decreases, such as the total distance an arm can be raised.
- It's hard to move your arms, legs, and neck.
- Losing balance and falling frequently.
- Joint movement is limited, and the body's flexibility is very low.
- There may be severe pain and soreness in the muscles.
- Involuntary muscle twitching and twitching (myoclonus).
In some severe cases, a condition called ``contracture'' can develop. This means that the joints are locked in place, and the muscles, tendons, tissues, and skin become permanently stiff, causing the joints to become stiff and rigid. When this ``contracture'' occurs, it is very difficult to move the affected body part.
What are the causes of Hypertonia?
The main cause of hypertonia is a communication defect in our central nervous system – that is, the brain and spinal cord. This system controls the interaction between nerves and muscles.
Muscle tone is controlled by pathways that connect nerves to the brain. If these pathways are damaged or blocked, the muscles cannot properly 'hear' the signals coming from the nerves. When muscle tone increases, the brain cannot tell the nerves, 'Okay, relax your muscles now.'
There are several reasons why the nervous system can be damaged in this way and cause hypertonia:
- Birth injury: For example, if the baby is deprived of oxygen while coming out of the mother's womb (birth canal).
- Brain tumor.
- Conditions that affect the way nerves communicate with muscles.
- Other types of damage to the central nervous system.
- Problems that occur during fetal development.
- Stroke.
Other conditions that have hypertension as a symptom
Hypertonia can be a symptom of several conditions that affect communication between the brain and the body's nerves and muscles. If a doctor diagnoses your baby with hypertonia, they will also examine your baby to check for other conditions that affect the central nervous system, such as:
- Cerebral palsy
- Multiple sclerosis
- Parkinson's disease
How is Hypertonia diagnosed?
To diagnose whether your baby has this condition, the doctor will first examine the baby's physical characteristics. There, they will pay attention to the following things:
- Balance and coordination.
- Motor skills: This means things like how to hold something, how to move your arms and legs, and how to sit up.
- Reflexes.
- Nerve function.
This test is not painful for the baby. Usually, a device like a reflex hammer is used.
The doctor will also ask about your family medical history . They will also find out if there were any complications before or during the baby's birth, and if this condition is the cause.
Tests for identification
If your doctor suspects hypertension, they may order several other tests to confirm the diagnosis. These tests include:
- Imaging tests to look at the brain and spinal cord: For example , an MRI scan or a CT scan .
- Electromyograms (EMG): This measures muscle and nerve activity.
How is Hypertonia treated?
Treatment depends on the severity of the hypertension condition and is primarily focused on managing symptoms.
Here are some treatments that can be used for hypertension:
- Exercise regularly, as much as possible.
- Attending physical therapy to improve your range of motion is very important. A physiotherapist teaches you how to loosen up tight muscles and make movement easier.
- Localized injections, such as botulinum toxin, are given directly into the affected muscles. This temporarily blocks nerve signals.
- Giving muscle relaxant medicine to reduce muscle spasms.
- Treating another underlying medical condition that has hypertension as a symptom.
Additionally, there are treatments available to improve mobility and ensure safety for people with hypertension, especially to reduce the risk of bone fractures from falls. Many people with severe hypertension use mobility equipment as a safe way to get around the world.
How quickly can I expect to recover from treatment?
Hypertonia is a lifelong condition, but with treatment, you can improve over time. The goal of treatment is to reduce symptoms and improve muscle function. How quickly you feel better depends on the cause and severity of the condition.
How can you reduce the risk of having a child with hypertension?
It is difficult to reduce the risk of having a baby with hypertension. This is because the cause is often not preventable, especially if it is related to an underlying medical condition. However, your doctor will work with you to discuss the safest ways to reduce birth injuries and labor complications during delivery. These things can help reduce some of the risk of developing hypertension.
What to expect if you have a child with hypertension?
Because hypertension is a lifelong condition, the prognosis depends on the cause of the diagnosis. Some children may feel better after long-term treatment, and the condition may not have a major impact on their overall health. However, in severe cases, hypertension can get worse over time. This can affect the child's overall health and well-being. In some cases , permanent immobility may occur. There is also an increased risk of falls, infections, and bedsores . Treating the underlying cause of hypertension can improve the child's outlook.
How do I take care of my baby with hypertension?
It's important to support your baby with this diagnosis. It may take a little longer for your baby to develop motor skills – things like grasping, reaching for objects, and crawling. However, by working closely with your baby's doctor and following the recommended treatment, you can help your baby's symptoms improve and reach age-appropriate developmental milestones .
As the child grows, long-term care may be needed. For example, continuing physical therapy can help improve their mobility as they become more involved with the world around them.
When should you see a doctor?
If your baby is showing symptoms of hypertension, you should definitely see a doctor. Such symptoms include:
- If you have difficulty moving your arms, legs, or neck.
- If the baby feels stiff when you touch it, even when it is just sitting.
- If your muscles seem to be twitching or twitching uncontrollably.
What questions should I ask the doctor?
It's a good idea to ask these questions when you see the doctor:
- "Are there any side effects to the medication prescribed to treat the baby's condition?"
- "How often should my child see a physical therapist?"
- "Is there another underlying medical condition causing my child's condition?"
What is the difference between Hypertonia and Hypotonia?
The difference between the two is simple. Hypertonia is when the muscles are too tight. Hypotonia is the opposite, when the muscles are too tight . Hypotonia is also known as 'floppy infant syndrome' . This is because there is no resistance from the muscles when the baby's body is moved, making the baby appear very limp and lifeless.
The message we want to take home from this story is
It can be really frustrating to hold your little one, feeling like they're a statue. But remember, there are treatments for this. Because hypertonia prevents your baby's muscles from relaxing, as they grow and reach their age-appropriate developmental milestones, they 'll need a little extra help from you and your doctor.
Being patient with your child's treatment, (often long-term), is a big part of helping your child live with this condition called Hypertonia. You are not alone, doctors and physical therapists are there to help you and your baby.
