There are more than 650 skeletal muscles in the body, which contract in order
to close the joints and cause the bones to move. However, all these movements
take place as the result of an extraordinary co-ordination in the body.
A neuropathic disease, the ALS is known as the disease that the
world-renowned English scientist Stephen Hawking suffers from. The
disease causes degeneration in the motor neurons (motor movement
nerve cells), which regulates locomotion. It does this by traveling from
the brain to the spinal cord, and from there to the muscles. When the
nerves that trigger muscles are impaired, the muscles cannot be stimu-
lated. As a result, patients lose their speech and movement functions in
a short time. Starting with the weakening of the arm and leg muscles,
and gradually affecting speech, chewing and respiratory functions, the
