If you have been feeling some pain in your wrist, weakness and lack of energy in your arm, chances are you are working long hours with a mouse and have not been resting.

The majority of us when using an average mouse we tend to have our palm facing downwards and place our palm on top of the mouse, using our thumb and pinkie to control the mouse. This method of operating a mouse is so common we do not feel that there is something wrong. It is an unknown fact that the above mentioned way of using a mouse has its flaws and it will hurt our wrist and carpal tunnel if one is using a mouse at work for a long period of time.

The position of the palm facing downwards and align to the table, is sometimes referred to as the ?pronated position?. When we are using our mouse in this position, the bone in the forearm has to twist together with our wrist. This causes extra pressure and this pressure is normally directed on to the carpal tunnel. If you add it up with bad position of hand while seating in front of a computer this effect might be worse.

The prolonged pressure onto the carpal tunnel might cause uneasiness to your wrist and arm and this is sometimes thought of as the Carpal Tunnel Syndrome. RSI or Repetitive Strain Injury can also occur when someone uses something excessively, for example an instrument of music, a type writer and in this instance a computer mouse. Constant long hours with a mouse in the pronated position can cause injury to the tissue and in some cases might lead to aching to some other area of the body.

The ?true? ergonomic mouse that is designed to be vertical in nature aims to minimize the pain and stress felt after prolonged hours of working with a mouse on the pronated position. With a mouse that is vertical, a user will have to use the mouse with their palm in the upright natural position. This hand shake like position avoids the turning of the arm, relieving pressure to the wrist and carpal tunnel.

This particular design of vertical ergonomic mouse is thought to have been working by a lot of user suffering from RSI. If you are a person who works long hours with a mouse you might give it a try to prevent getting RSI. Although some have managed to relieve themselves off fatigue and pain, taking enough rest and not stressing yourself is still a better way to go.
