An ergonomic vertical mouse will change the position of your hand and help to relieve the aches and pains associated with extended use of a computer mouse.
Typically, this change in posture is to one of a more natural posture that people often report as “more comfortable” than the hand position used for a traditional mouse. If you are experiencing aches and pains in your wrist, hands, forearm, elbows or shoulders, you may find that by simply changing the position of your hand (to more a handshake position) can help to reduce or even eliminate it.
