Hemiparesis Definition

Hemiparesis is a general term of the mild to moderate degree of muscle weakness. It will happen when one side of the body gets weak and impacts the limbs and facial muscles.

It will affect the 8 people out of every 10 stroke survivors. The patients who have hemiparesis are experiencing limited movement in their legs, facial muscles, hands, and arms.

This weakness on one side of the body can make difficult to perform everyday activities. Experiencing this pain on one side of the body can cause:

  • Difficulty in walking 
  • Difficulty in grasping the objects
  • Cause the muscle fatigues 
  • lack of coordination
  • Loss of balance 

Hemiplegia Definition

Hemiplegia is the symptom that occurs after the damage of the Central Nervous System like the stroke. It will affect the part of the one side part of the body and cause.

Such as it affects your left side, then it will cause the pain on the left side of the body. It will cause abnormal muscle tone, loss of motor skill, loss of posture control and loss of sensory factor.

Hemiplegia symptoms are more severe than the hemiparesis. It will cause a complete loss on the affected side body or paralysis may not be extensive. Some symptoms of the hemiplegia are difficult to control your bladder, speak and control your bowl. 

Forms of Hemiparesis 

The people who are experiencing the hemiparesis may have difficulty moving their legs, arms, walking and they may also have a loss of balance.

Due to this, performing everyday activities such as eating, grabbing objects, dressing, or even using the bathroom become more difficult.

The loss of abilities that relate to the stroke or the hemiparesis and also depend upon the area of the person’s brain that has been changed. Here are some forms of hemiparesis: 

1. Right side hemiparesis

The right side hemiparesis involves the injury to the left side of the person’s brain. Because the left side of a person’s brain controls the language and speaking.

The person who experiences this type of hemiparesis can also experience difficulty in talking and also understanding what the other people say. As well as they don’t determine left from right. 

2. Left Side Hemiparesis 

The left side hemiparesis involves the injury to the right side of the brain. The right side of the controls the learning process, certain types of behavior, and also the non-verbal communication.

The injury in this area of a person brian may also cause the people to talk excessively. They also experience short attention spans and memory problems. 

3. Ataxia

Ataxia involves the injury to the lower portion of the brain. This kind of injury may affect their body’s ability to coordinate the movement.

The result is referred to as the ataxia and it may also lead to difficulties with posture, balance, and walking. 

4. Pure Motor Hemiparesis

Pure motor hemiparesis is one of the most common types of hemiparesis. People who are experiencing this type of hemiparesis also experience the weakness in their leg, face, and arm.

In this condition, a person may also affect the person’s body parts equally, or it may affect the one body part more than others. 

5. Ataxic Hemiparesis Syndrome

The Ataxic hemiparesis syndrome that involves the weakness or the clumsiness on the one side body.

This condition of a person’s leg is often more affected than their arm. The symptoms of ataxic hemiparesis syndrome happen over a period of the hour to days.

What Is The Difference Between Hemiplegia And Hemiparesis?

Hemiparesis is characterized by the weakness on one side of the body parts. The person who is suffering from the hemiparesis may not be able to move their one side arms or they may feel tingling or other odd cessation on the just one side of the body. 

Hemiplegia is characterized by the paralysis on one side of the body. Though the stereotypes of the paralysis also suggest that paralysis completely removes the ability to move and the reality is a bit more complicated.

The people who are suffering from paralysis may retain some sensation, and the degree to which they are and also paralyzed can change over time. Thus it can be hard to establish a clear line that will separate the hemiparesis and hemiplegia. Particularly in the case of the milf hemiplegia and the severe hemiparesis.

Symptoms Of The Hemiparesis 

Symptoms Of The Hemiparesis

The most common symptom of the hemiparesis is partial paralysis or weakness on one side of the body. The symptoms of the hemiparesis depend on the side of the brain or spine code which is damaged.

The injury of the left side brain can cause the numbness on right side of body. If the injury is caused on the right side of the brain, then it will cause left-sided weakness.

The  Symptoms of the hemisphere depend on the type of spine injury and also it will depend on the level of the injury.

Causes Of The Hemiparesis 

Causes Of The Hemiparesis

The brain and spinal cord control the muscle movements. So, if the brain or spinal cord is damaged then they are not able to control or direct the muscles. Some of the most common cause of the hemiparesis are:

  • Stroke 
  • Traumatic injury may affect the brain, nerves or spine.
  • Congenital medical conditions like cerebral palsy, which is present from birth which may cause weakness on one side of the brain. Like it will cause numbness on the right side of the body 
  • Spine Disease
  • Brain or spine Tumour
  • Infection on the brain, meninges or spine
  • Psychiatric or psychological condition
  • Postictal paralysis
  • Inflammatory and autoimmune conditions

Which Side Of The Brain Is Worse To Have A Stroke?

Which Side Of The Brain Is Worse To Have A Stroke?

It’s difficult to say that what’s the side of the brain is worse to have a stroke. Because most of the stock is happen when the supply of the oxygens is cut off some position of the brain.

This will cause the brain cells to die, so the area which is responsible for the strength and movement of the body is damaged. This process will cause the hemiparesis.

Just like the left side of the brain, have control of speaking and understanding language ability. The right side of the brain controls those speaking, paying attention and motor skill abilities.

Which side of your body effects depends on the affected part of the brain. If the stroke will happen on the left side of the brain. Then you have muscle weakness or left side of body pains.

Just like if you have a stroke on the left side of the brain, then you have numbness on right side of body. But in some people pain in body or weakness occurs on the opposite side of the brain injury. 

Treatment Of Hemiplegia And Hemiparesis 

Treatment Of Hemiplegia And Hemiparesis

The treatments of the hemiplegia and hemiparesis depend on the injury of the brain and spinal cord. But doctors are recommending some treatments to treat this condition.

Here are some recommended treatments:

Physical Therapy

In this treatment, physical therapists will prevent atrophy and also prevent muscle spasticity. The physical therapist gives this therapy by keeping the joints loose and flexible To treat hemiparesis. 

Occupational Therapy

Occupation therapy can help to treat the weakness on one side of the body. This therapy or technique you can learn by taking care of common and with some activities. 

Electrical Stimulation

During the electrical stimulation, the physical and occupational therapist attaches the small electrical pads on the weaker extremities. They send small electrical currents through these pads to make the muscle contract.

After some time of this therapy, the weaker muscles will train and become stronger again. According to the one study, researchers have tested this electrical stimulation on 10 people who are suffering from the numbness on right side of body.

They gave them electrical stimulation in addition to kinesiotherapy for 7 weeks To treat hemiparesis.

After the weeks they had found improved moments in strength, mobility, and endurance. Because kinesiotherapy is becoming more effective when it comes to electrical stimulation. 

Aids Mobility

Using wheelchairs and walkers can help the hemiparesis patient to lead an independent life. 

Adaptive Equipment

Practicing day to day tasks can help to treat the hemiparesis. Doing cleaning, eating, driving and doing some more activities. 

Assistive Technology

Using assistive technology like voice-activated devices can help to do work more productively. 

Modified Constraint-Induced Movement Therapy

In this therapy, the stronger side of the body can focus on the weakness part of the body to compensate. This action will help to strengthen the weaker side muscles and treat hemiparesis.

According to one study, the researchers had tested this therapy of the 30 people who are receiving from the stroke. They practice this therapy for 4 weeks and gently notice them. After the 4 weeks, they had noticed the improvement in mobility in these participants. 

How To Diagnosis The Hemisparesis

If the person has any symptoms of the hemiparesis, then their doctor will do a physical examination. It can be difficult to determine whether the patient’s symptoms are the result of pain, weakness, or also another cause.

The physical examination will include testing the reflexes, strength, and sensation.

Then the doctor will also rate the strength of the sale of 1-5. This rating can also help the doctor to assess the patient’s strength at a later time, as it can be used as a comparison of the strength.

The hemiparesis diagnosis also confirms the imaging studies, which may also include the following. 

  • CT scan of brain or spine 
  • MRI brain or spine
  • Complete Blood test 
  • X-ray
  • Electromyography EMG
  • Myelography

Is It Possible to Recover From Hemiparesis?

Yes, It is possible to recover from the hemiparesis but you may not regain your full pre-stroke level of the strength.

According to the president of the American Association of Nurse Practitioners, the full recovery from hemiparesis will take a week, month, or even years, but with regular rehabilitation exercises and therapy can help to accelerate recovery.

To improve the outlook, start rehabilitation as soon as possible. Also, be sure to follow the doctor’s treatment plan, and also the medical team will know about any changes in the condition.

Working towards the smaller and short terms goals will help to feel like the treatment is more attainable too. 

Recovery Of Hemiparesis

Physical and also occupational therapy is important for the recovery of hemiparesis.

This therapy may include the use of electrical stimulation to the brain, imagery, and also the use of assistive devices such as a cane, wheelchair, or walker.

Also, the modifications to the home may need to be made to accommodate and help to increase mobility. Here are some of the modifications:

  • Raise the toilet seats
  • Ramos
  • Grab the bars
  • Non-slip adhesive strips in the bathtub
  • Electric razors
  • Electric toothbrushes
  • A bench in the tub

How Does A Stroke Cause The Hemiparesis

In most of the cases, the strokes happen when the supply of oxygen is cut off to a portion of the brain, causing the brain cells to die.

When the areas of the brain which are responsible for the movement, damage, and strength of the body can lead to hemiparesis.

The side of your body that gets weakened by the stroke can be determined by the affecting part of your brain. For example, if the strike happens on the left side of the brain, then the left side of the body muscle gets weak.

That is referred to as ipsilateral, or on the same side as the injury. While in some cases, though the weakness may contralateral or on the opposite side of the injury.
