Have you ever wondered what it would be like if you suddenly couldn't move an arm or a leg, or if you felt like a part of your body was slowly losing its life? It's a really hard experience to imagine, isn't it? This is the state of not being able to move our muscles at will, which is what we call `` Paralysis '' in medical science. This happens because of some problem in our nervous system. Because, the nerves give the signal that our muscles need to move. So, when you get paralyzed , you can't move some parts of your body. Let's talk about this in a little more detail , okay?

What exactly is paralysis?

Simply put, paralysis is the inability to control the muscles in your body voluntarily, that is, of your own free will. This is caused by our nervous system. Think of it like a cable that carries messages from our brain to our muscles. If there is a problem somewhere in this cable, the message does not go through properly. That is when the muscles stop working, which means paralysis . This paralysis can affect any part of the body. Also, there are two main ways to do this:

• Partial paralysis / Paresis: This is when you can control some muscles, but it's hard to control others. It's not completely paralyzed, but it feels weak.
• Complete paralysis: In this case, you cannot control any muscles in the area.

Also, depending on where the nervous system is damaged, paralysis can be divided into two types:

• `Flaccid paralysis`: In this, your muscles become very weak and limp, like a lifeless piece of cloth.
• Spastic paralysis: This is when the muscles become stiff and twitch frequently (spasticity). To be precise, the muscles simply contract and twitch as they please.

How common is paralysis ?

Did you know that in the United States alone, about 5.4 million people, or about one in every fifty, are reported to have some form of paralysis? There is some good news. Some people have this paralysis temporarily , and over time, they gradually or completely recover. For example, in a condition called `Bell's palsy`, the muscles in the face are temporarily paralyzed, but they often recover. `Palsy` is a condition that causes paralysis and shaking. However, ` Permanent paralysis` means that you will never be able to control your muscles again. That is, you cannot reverse the condition.

What are the different types of paralysis?

We also classify this according to the area affected by the paralysis.

• Localized paralysis :This affects a small area of ​​the body. This condition is most commonly seen on the face, hands, feet, or vocal cords.

• Generalized paralysis: This affects a large area of ​​the body. This is further divided according to the extent of the effect:
• `Diplegia`: This is when the same area of ​​the body is paralyzed on both sides. For example, both arms, both legs, or both sides of the face.
• `Hemiplegia`: This is when one side of the body is completely paralyzed. That is, both the arm and leg on one side. Imagine, let's say someone has a `Stroke` and their right side is paralyzed, that's how it is.
• `Monoplegia`: In this, only one arm or one leg is paralyzed.
• Paraplegia: This involves paralysis of both legs. Sometimes the lower abdomen can also be affected.
• Quadriplegia (or Tetraplegia): This involves the loss of all four limbs and often the trunk. People with quadriplegia may also lose all movement from the neck down.

What are the symptoms of paralysis?

If you have paralysis, the main thing is that you can't move the affected part of your body, some or all of it. Sometimes, depending on the area of ​​the injury, you may lose feeling in that area as well. Some people are born with paralysis, for example with conditions like cerebral palsy. Strokes and spinal cord injuries can cause paralysis suddenly . Some conditions can also cause paralysis gradually . In such cases, you may experience symptoms such as:

• Gradually, sensation and muscle control decrease.
• Muscle cramps.
• Tingling or numbness in the limbs.

What are the causes of paralysis?

As we have discussed before, paralysis occurs because of a problem with our nervous system. Our nervous system is like the message center of our body. It carries signals from the brain throughout the body and tells it what to do. So if something is damaged in this nervous system, those messages don't get to the muscles properly. Most of the time, it's a traumatic injury or a medical condition that damages the muscles and nerves. Stroke and spinal cord injuries are the two main causes of paralysis. There are other causes, including:

• Some conditions are present at birth, for example `Spina bifida`.
• Autoimmune diseasesAutoimmune diseases are diseases in which our own immune system works against our own body. Examples: Multiple sclerosis (MS) and Guillain-Barré syndrome.
• Brain injuries, such as traumatic brain injury and cerebral palsy.
• Neurological diseases, for example, Amyotrophic lateral sclerosis (ALS).

What are the possible complications of paralysis?

Paralysis can affect our breathing muscles and heart rate. It can also affect other body systems in the affected area. Depending on the type of paralysis, you may be at risk for:

• Difficulty breathing, cough and pneumonia .
• Blood clots and deep vein thrombosis ( DVT ).
• Difficulty speaking or swallowing ( Dysphagia ).
• Depression and Anxiety .
• Erectile dysfunction and other sexual problems in men.
• High blood pressure (Autonomic dysreflexia) or low blood pressure (Orthostatic hypotension) and heart disease.
• Urinary incontinence and loss of bowel control.
• Pressure injuries / Bedsores and blood poisoning (Sepsis).

Important: Not everyone will experience these complications, but it is important to be aware of them so you can seek medical advice quickly.

How to recognize paralysis?

When you go to see a doctor, he or she will examine you and ask about any accidents you have had. If your paralysis is gradual, he or she will ask how long you have had this problem. To find out more, your doctor may order one or more of the following tests:

• X-ray tests: To see if bones are broken and nerves are damaged.
• Imaging tests: A CT scan or MRI can be done to look for signs of a stroke, brain damage, or spinal cord damage. A full-body imaging scan can look at bones, muscles, and tissues.
• Myelogram: This checks for damage to the spinal cord and nerves.
• Electromyogram (EMG): This tests the electrical activity of nerves and muscles.
• ``Spinal tap (Lumbar puncture)'':This involves taking spinal fluid and checking it for infections, inflammatory conditions, and diseases like multiple sclerosis (MS).

Is it possible to recover from paralysis?

In fact, there is currently no cure for permanent paralysis. However, temporary paralysis conditions like Bell's palsy often resolve over time without treatment. In some cases, some improvement can be seen, especially within the first year.

How is paralysis managed or treated?

Treatment for paralysis usually includes physical therapy, occupational therapy, and speech therapy. These rehabilitation services include helping people adjust to their paralysis, providing exercises, and providing adaptive and assistive devices to help them perform daily tasks. These can help people with paralysis live independently and have a better quality of life. Other treatments depend on the cause of the paralysis and how it affects you. Your doctor may recommend the following along with rehabilitation:

• `Adaptive equipment`: Equipment that helps people eat independently and drive vehicles.
• Assistive equipment: Wheelchairs, Scooters, Crutches and Canes.
• Orthotic/prosthetic devices: For example, braces.
• Voice-activated technology: Use computers, lighting systems, and telephones.
• Treatment for complications of paralysis, for example, spasticity and urinary problems.

How to prevent paralysis?

Spinal cord injuries are the leading cause of paralysis. So, here are some steps you can take to reduce your risk of spinal cord injury:

• Always wear a seatbelt when riding in a vehicle. Make sure that small children are properly using a car seat or booster seat.
• Check the depth of the water before jumping into the water.
• Do not drive under the influence of alcohol or drugs, and do not travel with someone who is under the influence.
• Follow safety precautions when playing sports or engaging in other activities. For example, wear a helmet when playing sports or riding a bike. Have someone help you when doing things like gymnastics, and use cushioning mats where necessary.
• Never move someone who you think has a head , neck, or back injury. Immediately call 1990 (if in Sri Lanka) or the appropriate emergency service.

What is the prognosis for people with paralysis?

Learning to live with paralysis can be a challenge. It can change your life, the things you do, and even the way you think about yourself. These changes can lead to mental health problems and depression. So talk to your doctor about getting support, both physical and emotional. With time and rehabilitation, many people with paralysis adapt to their condition. Many people live independent, active lives with their paralysis. People with quadriplegia (the loss of all four limbs) often need help from others throughout their lives, but they can still keep their minds active.

Maintaining a healthy lifestyle is very important to reduce the risk of complications from stroke. It is generally recommended to choose exercises that suit your abilities and maintain an exercise routine.

When should I see a doctor?

If you have symptoms of a stroke, or if you think someone has suffered a head , neck, or back injury, you should call 1990 immediately. Also, seek medical advice immediately in the following situations:

• Difficulty breathing, swallowing, or speaking.
• It feels like numbness in the limbs or something.
• Muscle weakness (it may be constant or come and go).
• Suddenly unable to move your muscles.

What questions should I ask my doctor?

You can ask your doctor questions like these:

• Is this paralysis temporary or permanent?
• Will I ever regain some mobility? If so, how long will it take?
• What is the best treatment for me?
• What kind of mobility or assistive devices can help me?
• Should I be concerned about symptoms of complications?

Paralysis is a life-changing condition. Even temporary paralysis can affect your ability to do the things you love. If paralysis occurs suddenly, it can be challenging to adjust to major lifestyle changes. Your doctor can guide you through the rehabilitation and mental health services available to you. Many people with paralysis live active lives with assistive devices and the support of loved ones. So it's important to stay strong.
