Simple Steps to help you determine" How to Choose an Ergonomic Computer Mouse Designthat is Best for You":
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. Read more about Computer Mouse designs, including the Contour Perfit computer mouse that comes in multiple sizes for left and right hand users.
  • 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!!!!) Contour RollerMouse Station and RollerMouse PRO offer incredible solutions

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.
  • Make sure your Computer mouse is compatible with your dominant handedness. If you are left handed- you must use a left handed computer mouse. See Contour Perfit Computer Mouse for Left Hand and Evoluent Vertical Mouse for Left Hand. Contour Perfit Mouse offers 3 sizes in the left-hand version and five sizes in the right -hand version.
  • 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. Now recently, Contour Design announced the release of its second-generation RollerMouse input device, appropriately named the RollerMouse PRO. Contour's RollerMouse input device series is designed to reduce or eliminate the need for a mouse by offering a "rollerbar" and set of buttons below the keyboard navigate and click with a cursor.
  • 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.
  • Take Action to Improve Your Mouse: If you suffer from pain, have carpal tunnel syndrome or other computer-related cumulative trauma disorder, it is highly recommended that you change your computer mouse to eliminate excessive stress and pressure on your working tendons. The best computer mouse design solutions for carpal tunnel syndrome and any injury are the Contour RollerMouse Classic and Contour RollerMouse Pro, the Contour Perfit Computer Mouse and the Evoluent Vertical Computer Mouse.
