Weakness of a Limb Overview

Another name for Weakness of a Limb is Limb Weakness.

What is limb weakness?
A person with limb weakness has lost strength in an arm or leg. Weakness may be caused by a malfunction of the brain, the spinal cord, or nerves. These structures transmit signals from the brain, which stimulate the muscles to move the limb. The location of the limb weakness can provide a clue to the underlying cause.

What are the symptoms of limb weakness?
Limb weakness may occur on both sides of the body, or limb weakness may occur only on one side of the body. Symptoms that may occur with limb weakness include limb numbness and limb pain.

How does the doctor treat limb weakness?
Treatment for limb weakness depends on the underlying cause.
