Carpal Tunnel Syndrome (CTS) is the inflammatory disorder that is caused due to repetitive stress, physical injury or any other condition that causes the tissues around the median nerve to inflated. The carpal tunnel is a small canal or tunnel runs from the forearm through the wrist. Bones form three walls of the tunnel, which are bridged by strong, broad ligament.The median nerve passes through this tunnel, which actually supplies feeling to the thumb, index, and ring fingers, the nine tendons that flex the fingers and also provides function for the thenar muscles, which are actually the muscles at the base of the thumb.

When the protective lining of the tendons within the carpal tunnel become inflamed and swell or when the ligament that forms the roof becomes thicker and broader leads to Carpal Tunnel Syndrome. The result is compression on median nerve fibers due to the swollen tendons and thickened ligaments; there will be slow down in the transmission of the nerve signals through this carpal tunnel. This ultimately results in pain, numbness, and tingling sensation in the wrist, hand, and fingers.

Carpal tunnel syndrome is also categorized as Cumulative Trauma Disorder, overuse syndromes, chronic upper limb pain syndrome, or repetitive motion disorders which are all associated generally with repetitive and forceful use of the hands that damages the muscles and bones.  Many believe that constant repetitive use of the hand and poor computer set-up  are the primary causes the Carpal Tunnel Syndrome.

Causes of Carpal Tunnel Syndrome: 

The main Carpal Tunnal Syndrome causes is the repetitive motion at workplace. These cases contribute to half of the work associated illness and the Carpal Tunnel Syndrome they account for nearly half of all reported work-related illness, and Carpal Tunnal Syndrome is estimated to account for over 41% of the disorders caused due to repetitive motion. The primary ergonomics risk factors in the workplace that cause Carpal Tunnel Syndrome are: Repetition, High force, Awkward joint posture. Direct pressure, Vibration, and Prolonged constrained posture. Repetitive typing.  Read more about "Ergonomics Risk Factors"

The main cause of the computer-related Carpal Tunnel Syndrome is the incorrect posture-which produce the ergonomics risk factors noted above, especially in computer users. The rolling of the shoulders forward, rounding the lower back and thrusting the chin forward, shortens the neck and the muscles of the shoulder, there by compressing the nerves in the neck which ultimately have an effect on the wrist, fingers and the hand.
