Sensations and movements of the upper limbs (shoulders, hands and forearms) are controlled by a set of nerves which are called Brachial Plexus. This group of nerves begin from the neck region and spread across the entire spinal region. The sensation producing nerves can be affected due to any injuries in these places, which in turn, will cause problems in the motor functioning of the limbs.
HOW IS BRACHIAL PLEXUS DIAGNOSED?
1 to 3 newborn babies out of 1000 births, suffer from Brachial Plexus.
