If you or a loved one have hemiplegia, it’s crucial to know about this condition. Hemiplegia comes from brain damage or spinal cord injury. It causes paralysis on one side of the body. This means you can feel weak, have trouble controlling your muscles, and feel muscle stiffness.

Treatments for hemiplegia focus on the cause. They could include physiotherapy, mCIMT, assistive devices, mental imagery, and electrical stimulation.

What is Hemiplegia?

Hemiplegia happens due to brain damage or spinal cord harm. It causes paralysis on only one side. If it starts before birth or within 2 years of life, it’s congenital. If it starts later, it’s acquired.

Hemiplegia Definition

Hemiplegia is a condition where one side of the body can’t move. It’s because of damage on the other side of the brain or spine. This means that the muscles don’t work on one side.

Hemiparesis vs. Hemiplegia

Hemiparesis means there’s a little weakness on one side. Hemiplegia is when the strength is fully lost on one side. Often, hemiparesis comes before hemiplegia.

Hemiplegia vs. Cerebral Palsy

Cerebral palsy includes many disorders that affect moving and muscle skills. Hemiplegia is a kind of cerebral palsy with paralysis on one side. But, not all cerebral palsy cases have hemiplegia.

Hemiplegia Symptoms

Hemiplegia happens when one part of your body is paralyzed. It shows up in ways that can really affect how you move and live. By knowing these symptoms, you can make it easier to deal with them.

Muscle Weakness and Stiffness

In hemiplegia, you will notice weak or stiff muscles on one side. You might see the muscles getting tight and hard to move, which is called spasticity. This makes simple actions like walking, holding things, or using your hands tough.

Poor Motor Skills and Balance

This condition can mess with how well you move and stay balanced. It can be hard to do simple things like walking or standing without help. You might also find stairs or rough ground really tricky to navigate. This hurts how freely you can move and do things by yourself.

Causes of Hemiplegia

Many things can cause hemiplegia. Each cause is different. Knowing the causes helps doctors treat it right.


Stroke is a top cause of hemiplegia. It happens when blood flow to the brain stops. This causes brain damage and paralysis on one side.

Quickly spotting and treating stroke symptoms is key. It lowers the chance of long-term hemiplegia.

Brain Infections

Brain infections like encephalitis or meningitis can lead to hemiplegia. These infections cause brain swelling. It harms the brain and affects body movement on one side.

Brain Trauma

Traumatic brain injuries from accidents or falls are another cause. When the head is hit, it can damage brain areas. This damage results in paralysis on the other side.


Sometimes, genetic factors play a role in hemiplegia. Conditions like Alternating Hemiplegia of Childhood (AHC) come from certain gene mutations. This can cause hemiplegia episodes.

Brain Tumors

Brain tumors can lead to hemiplegia too. Both benign and malignant tumors can damage the brain. This results in paralysis on one side.

Knowing about hemiplegia’s causes is crucial for doctors. It helps them make the best treatment plans. This care is vital for those with hemiplegia.


Types of Hemiplegia

Hemiplegia can show up in many different ways. Each type has its own features and effects. It’s key to know the types to diagnose and treat them right.

Facial hemiplegia affects the muscles on just one side of your face. This makes your face look uneven. It also makes it hard to show emotions. Eating, drinking, and talking can become difficult tasks.

Spinal Hemiplegia

Spinal hemiplegia causes paralysis on one side due to spinal cord issues. It’s often because of injuries, tumors, or certain diseases.

Contralateral Hemiplegia

Contralateral hemiplegia is when one side of the body is paralyzed, opposite to the brain’s issue. This happens because the brain’s motor signals cross over in the body.

Spastic Hemiplegia

In spastic hemiplegia, muscles on one side are very tight and have spams. This makes the body stiff and hard to move. Posture might look strange too.

Alternating Hemiplegia of Childhood

Alternating hemiplegia of childhood is rare and genetic. It causes episodes where hemiplegia switches sides. Something specific can trigger these episodes, and they might last for hours or days.

mCIMT is a special type of therapy that helps the arm or leg that doesn’t work well. It involves using the weak arm or leg more while holding back the strong one. This makes the brain learn to use the weak one better.

Assistive Devices

Devices like canes or walkers can be very helpful for those with hemiplegia. They make moving around easier and safer. This way, people can do more things by themselves every day.
