Why Are There So Many Computer-Related Injuries with Computer Mice?
These are the primary reasons why so many computer users have reduced productivity, discomfort, pain and even injury, an ordinary computer mouse just is not the best-fit solution for most people, here is why:
Shape: the shape of an ordinary or generic computer mouse that does not correctly fit the user's hand, requires the user to grip and hold, which over an extended period will cause tendon and muscle fatigue in the hand, wrist and even the elbow and arm.
Overall size: the size of the computer mouse does not properly fit the size of the individual’s hand. This means there is not enough support for the hand, having optimal support and comfort is required to minimize fatigue with computer mouse operations. Individuals with smaller hands should use smaller mice. On the contrary, individuals with larger hands should use larger mice.

Right and left hand compatibility- the computer mouse is not compatible with the user’s dominant hand. The computer mouse should be compatible with the dominant hand of the computer user, left-handed computer mouse users should use an ergonomic computer mouse designed for the left hand.
Wrist Position: An ordinary, generic horizontal computer mouse requires your forearm to twist away from its natural position, this causes more strain on your carpal tunnel, wrist tendons and ligaments. Read more about how the Evoluent Vertical Mouse eliminates arm twisting. The Evoluent Vertical Mouse supports your hand in a fully upright handshake position that eliminates the forearm twisting required by ordinary mice.
Motion: The side-to-side swaying and/or back and forth motion of a generic, ordinary computer mouse used to propel the cursor around the screen has been linked to several injuries, including tendonitis and friction burns from contact with the desk surface or mouse pad (make sure you use a gel-padded mouse pad wrist rest!!!!)

So, How do you Choose an Ergonomic Computer Mouse that best meets your needs?
The typical dimensions for a computer mouse are: Length- typical mouse dimensions are 4.6 inches to 5.75 inches. Width- typical mouse dimensions are 2.5 inches to 3.75 inches. Height- typical mouse dimensions are 1.0 to 2.0 inches. Make sure your hand measurements match those of the dimensions of the computer mouse. This will provide optimal support and comfort with minimal fatigue with mouse operations. Individuals with smaller hands should use smaller mice. On the contrary, individuals with larger hands should use larger mice
Ensure the proper size and fit of your computer mouse: Follow the Hand / Computer Mouse sizing chart guidelines. If you have a large hand, for optimal fitting, you must use a large sized computer mouse, if you have a small hand, for optimal fitting you must use a small computer mouse. Contour Perfit Optical Mouse comes in five different sizes for the Right hand computer mouse, three different sizes for the Left hand, it is the #1 recommended Ergonomic Computer Mouse for multiple size needs. Please see the Contour Perfit Computer Mouse Product Reviews and Product Awards this superior computer mouse has won.
Ensure the computer mouse contour and shape should fit the users hand: Typical shapes are the straight mouse or the kidney-shaped mouse. The contour of the mouse refers to how the mouse arches and conforms to the shape of the hand thus providing optimal postural support.
Reduce Excessive Side to Side and/or Back & Forth Motions, Contour Roller Mouse Classic was designed to reduce awkward computer mouse reach postures and ease computer-related pain of the shoulder, neck, elbow, wrist and hand. because it eliminates the side to side swaying and the back and forth motions required with traditional computer mouse use.

Button Size, Location and Activation Force: The button size should fit the dimensions of the fingers, the location of the buttons, usually top surface or lateral surface should be evaluated on an individual basis and determined by user preference. The button activation force should be minimized in order to reduce finger fatigue. Button activation forces should be approximately between 0.5 and 2.0 Newtons.
