Hemiparesis: muscle weakness on one side of the body.

  Articles

Hemiparesis is partial weakness on one side of the body. It can affect both the left and the right side of the body. Weakness can affect the arms, hands , legs , face, or a combination of both. About 80% of stroke survivors experience hemiparesis, making it one of the most common consequences of stroke .

People with hemiparesis can move the affected side of the body, but with limited force. One side of the body can become completely weakened and this condition is called hemiplegia.

Trauma to the left side of the brain usually results in weakness on the right side of the body. Trauma to the right side of the brain usually results in weakness on the left side of the body.

Depending on the type of spinal injury and the severity of the spinal injury, hemiparesis can affect the same side of the body as the spinal injury or it can affect the opposite side.

Some of the symptoms of hemiparesis are as follows :

  • Inability to balance
  • Dificulty to walk
  • Inability to grasp objects.
  • Decreased precision of movement.
  • Muscular fatigue
  • Lack of coordination
  • Leaning to one side when standing, walking, or sitting

This rating can also help when the same healthcare provider or other healthcare providers assess your strength later as it can be used for comparison.

Muscle strength scale

The scale for evaluating muscle strength is as follows:

  • 0/5: no movement
  • 1/5: mild muscle spasms
  • 2/5: Swing from side to side, but don't lift an arm or leg against gravity.
  • 3/5: Can move against gravity, but not against any force, such as a slight push from the examiner.
  • 4/5: Can move against a force, such as a push from the examiner, but not with the expected normal force.
  • 5/5: Can move against force with expected force

Diagnosis of the cause of hemiparesis can also be confirmed by imaging tests, which may include the following:
