Ergonomic Guidelines for a Computer Mouse:

1. Overall size should fit the size of the subject’s hand to provide optimal support and comfort with minimal fatigue. Use our sizing chart to ensure the proper size and fit, multiple size options are recommended for small or large hands.
2. If you have a small hand, fit your computer mouse to your hand with the appropriately sized small computer mouse. See sizing chart.
3. If you have a large hand, fit your computer mouse to your hand with the appropriately sized large computer mouse. See sizing chart.
4. Contour and shape should fit the user’s hand. Mouse arch should conform to the natural arch of the hand in a neutral position.
Typical shapes are straight or kidney shaped. Operating posture should encourage neutral positioning of the wrist, fingers and hand.
5. Button size should fit the dimensions of the user’s hand. The number and location of buttons should correspond to the predominant direction of flexion of the digits.
6. The mouse should be compatible with the user’s dominant handedness.

Ergonomic experts recommend the #1 rated Computer Mouse alternative: Contour Roller Mouse Station. Eliminate the computer mouse entirely by placing the mouse functions as a platform station, underneath your keyboard. Note: this product is not and does not include the keyboard. The Contour Roller Mouse Station is the platform underneath the keyboard shown in the photo to the right.

World's first handshake grip mouse series since 2002

The Evoluent™ VerticalMouse™ 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 Mouse cured their wrist or arm pain.

An ordinary horizontal mouse requires your forearm to twist away from its natural position.



No Retraining Necessary
The grip is the same as an ordinary mouse, just turned sideways, and the buttons are operated by the same fingers. There is virtually no retraining necessary.

The Evoluent Vertical 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.

Reduces Hand Movements
1200 dpi true optical resolution sensor moves the pointer quickly to reduce hand movements. The pointer can be moved across a 17" monitor with only 1/2" (13 mm) movement of the computer mouse. Most other computer mouse products have 400-800 dpi and require more hand movement.

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

Approved ergonomic mouse of University of California at Berkeley:

The Evoluent VerticalMouse 2 was evaluated in 2007 by a team at the health services clinic in UC Berkeley, including medical doctors, physical therapists, ergonomists, and administrators. It was found to be comfortable, easily adapted to, and promote a neutral wrist and forearm posture. It is the only vertical type computer mouse approved for staff use within UC Berkeley and for sale in the campus store.
