Computer Mouse for Carpal Tunnel Syndrome

Poorly-fit Computer Mouse: leading cause of Hand/Wrist & Elbow Injuries & Carpal Tunnel Syndrome

If you suffer from elbow pain or wrist/ hand pain, carpal tunnel syndrome or other computer-related cumulative trauma disorders, you must change your computer mouse, read the simple steps below to find the best-fit Ergonomic Computer Mouse for you.

**Even if you do not yet have pain, take immediate action and follow the simple steps below to ensure you are using a computer mouse that is appropriate for you. The use of a computer mouse or poor ergonomic computer set-up is a growing source of lost productivity and even injury!

Why? Because of the constant and repetitive motion involved and the stress on joints and muscles when put in poor positioning for hours at end.

How pervasive is the problem? Most days, just about everyone performs millions of keying, pointing and clicking functions on their computer!

Computer Mouse and Repetitive Motion Injuries: The drastic increase in repetitive motion injuries due to mouse use is largely due to the problem that the generic, computer mouse that ships with most computers does not properly fit the computer users hand! Hence, this generic computer mouse contributes to injuries that range from calloused hands and wrists, to carpal tunnel syndrome, and other cumulative trauma disorders

In fact, recent studies by Tech Dyne, International, Inc concluded that the use of a generic, poor-fitting computer mouse for a single four-hour period caused a loss of strength in the hand in arm of up to 60% and caused the muscles being used in these repetitive operations to get overused, causing inflammation and injury.

How can computer mice be potentially so harmful? Three primary reasons:

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. Read more about Computer Mouse designs, including the Contour Perfit computer mouse that comes in multiple sizes for left and right hand users.

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.

Contour RollerMouse Station Computer Mouse alternative

Motion: The side-to-side swaying 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.

Five Simple Steps: Take Immediate Action to Find the Computer Mouse that is Most Appropriate for You:

Measure Your Hand: The overall size should fit the size of the hand to provide optimal support & comfort with minimal fatigue. Use our hand / computer mouse sizing chart to measure your hand.

Multiple size Ergonomic Computer Mouse: Contour Perfit Computer Mouse

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.

Ergonomic Computer Mouse: Evoluent Vertical Computer Mouse

Make Sure the contour and shape of the Computer Mouse fits your hand/ wrist. Computer mouse arch should conform to the natural arch of the hand in a neutral position. Operating posture should encourage neutral positioning of the wrist, fingers and hand. Contour Perfit Computer Mouse design provides a superior contour to best fit the hand. If you wrist or hand is uncomfortable in the pronated (hand down) position, the Evoluent Vertical Computer Mouse is the #1 recommended and highly rated vertical computer mouse. This unique vertical design keeps the hand / wrist in an upright and neutral position. There truly is no other vertical computer mouse product that comes close to the superior Evoluent Vertical Mouse.

Evoluent Vertical Mouse is the world's first handshake grip computer mouse series since 2002. The Evoluent™ Vertical Computer Mouse™ 2 supports your hand in a fully upright handshake position that eliminates the forearm twisting required by ordinary mice. Once you experience the superior comfort, you will never go back to ordinary mice. (Patented.)

Eliminates Arm Twisting: The patented shape supports your hand in a fully upright handshake position that eliminates forearm twisting. Many users said the Evoluent Vertical Computer Mouse cured their wrist or arm pain. An ordinary horizontal computer mouse requires your forearm to twist away from its natural position.

Reduces Hand Movements: The Evoluent Vertical Computer Mouse 2 does not move sideways when clicking with normal force because the thumb naturally opposes the fingers. Pointer control is as accurate as any other good computer mouse.

Easy Clicking: The button force is light for easy clicking, but still firm enough to avoid accidental actuation.
