Ergonomic experts recommend the Evoluent™ VerticalMouse™ for all computer users. One of the biggest problems in computer use is a poor fitted computer mouse. If you do not properly fit your computer mouse to your hand, you may be causing excessive strain, fatigue and stress to your hand and wrist muscles and joints.
The Evoluent VerticalMouse 2 supports your hand in a fully upright handshake position that eliminates the forearm twisting required by ordinary mice. Ergonomically, this is the power position for the wrist and hand. This power position is when the grip is strongest and the stress on the joints and tendons is least. Repetitive mouse activities out of the power position may result in cumulative trauma or pain. This power position is also the optimal position for mouse utilization and can maximize muscle strength and reduced muscle fatigue and injury. Properly fitting the computer mouse to your hand is one of the easiest, most economical and effective solutions for improving workstation ergonomics.
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. The Evoluent Vertical 2 computer mouse was found to be comfortable, easily adapted to, and promote a neutral wrist and forearm posture. The Evoluent Vertical 2 computer mouse is the only vertical type computer mouse approved for staff use within UC Berkeley and for sale in the campus store.
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.
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.
Offers Effortless / Easy Clicking: The button force is light for easy clicking, but still firm enough to avoid accidental actuation.
