A central mouse is an ergonomic computer mouse designed to relieve the neck, shoulders, and arms when using a mouse. The mouse is right in front of you, between the keyboard and you. Unlike a traditional mouse, where you hold the mouse with one hand, you use the central mouse with two hands and your arms stay in the same position. This type of mouse promotes a natural (
in-line) working posture and is used to reduce physical complaints, such as pain in the neck, shoulders, arms and wrists.
