What is an Injury from abrupt jerk?

Answer 1

Abrupt jerks can be responsible for many injuries, but most commonly a jarring, jerking motion can cause brain and spinal cord injury.

In the brain, shaking or strong rotation of the head causes brain structures to tear. Nerve tissue is disturbed throughout the brain.This is called dffuse axonal injury.

In the spine, it could cause any of the following injuries:

* Anterior cord syndrome: characterized by damage to the front of the spinal cord, resulting in impaired temperature, touch, and pain sensations below the point of injury. Some movement can later be recovered.

* Central cord syndrome: characterized by damage in the center of the spinal cord that results in loss of function in the arms but some leg movement. Some recovery is possible.

* Posterior cord syndrome: characterized by damage to the back of the spinal cord, resulting in good muscle power, pain, and temperature sensation, but poor coordination.

* Brown-Sequard syndrome: characterized by damage to one side of the spinal cord, resulting in impaired loss of movement but preserved sensation on one side of the body, and preserved movement and loss of sensation on the other side of the body.

* Cauda equina lesion: characterized by injury to the nerves located between the first and second lumbar region of the spine, resulting in partial or complete loss of sensation. In some cases, nerves regrow and function is recovered.
