What is Paralysis?

Paralysis is the inability to move a part of the body due to loss of muscle function. Paralysis may be complete (permanent) or partial (temporary). It can occur suddenly or gradually.

Paralysis occurs when the brain is unable to pass the messages to the muscles via the spinal cord. This may be due to nerve damage at any place in the brain or spinal cord, which together constitutes the central nervous system (CNS). Usually, the region in the body, below the nerve damage is paralyzed. For example, if the middle or lower region of the spinal cord is damaged, then the legs are likely to become paralyzed. In this condition, the affected individual is neither able to move their feet nor feel any sensation, even though the outer appearance of the leg appears to be perfectly normal.

Approximately 5.4 million people (1 in 50) have paralysis in the USA.
