Ergonomic Mouse Research by Medical University: Intensive working with a conventional computer mouse may result in complaints like tingling, pain and /or obstruction of the blood flow to and from your arms and hands. Another symptom is a restricted rotation of the head. However excellent the functionality of the standard computer mouse - we all use it with great ease - most of the time it is too small for the hand while its shape forces your hand and fingers in an unnatural gripping position. It lacks comfort. Therefore a group of mechanical engineers, working in close co-operation with the Medical Center of Erasmus University in the Netherlands, have re-designed the mouse, and invented the ergonomic mouse called the Handshoe Mouse. Prevent RSI and Carpal Tunnel Syndrome: This innovative, patented, truly ergonomic computer mouse, has been field tested in large organizations for almost two years and has shown to reduce the complaints as well as the risk of Repetitive Strain Injury (RSI), Carpal Tunnel Syndrome and other Neck, Shoulder, Arms and Hands (NSAH) complaints. Instead of over-using your hand and wrist, your arm will most of the time let the optical Handshoe Mouse float without any effort. The shape allows for the hand to continuously rest on the mouse body in a relaxed fashion, so there is no skin contact between your hand and the desk. As a result there is no skin irritation as caused by excessive rubbing when moving a conventional mouse. Contrary to conventional computer mice you don't have to continuously lift (hover) the fingers, to prevent accidental switching. The buttons of this ergonomic mouse are positioned in line with the fingers. Only minor pressure is required to click the buttons. The thumb rest of the HandShoe Mouse allows for a relaxed position and prevents excessive thumb action which can be harmful. HandShoe = "Glove" In Dutch the word HandShoe means "Glove". The Handshoe Mouse "fits like a glove" or, like some people say "feels like a saddle for the hand". The HandShoe Mouse is available in three standard sizes (Small, Medium and Large) which are available in a wireless and a wired version. So there is a Handshoe Mouse for everyone! The HandShoe Mouse is developed, based on proper university research and measurements and not on beliefs of individuals
