Fundamental research by a Dutch university has shown that extending your hand and continous hovering of your fingers above the buttons of a conventional computer mouse causes an un-interrupted excessive load of your hand and fingers. The same study shows that this is also the case when using most, so called, ergonomic mice. Professor Han-Ming-Chen of national Taiwan university proved that the use of any non-slanted mouse will cause discomfort in your forearms and shoulders while using a mouse with a suitable slanted angle provides a more neutral hand position. It reduces forearm and shoulder muscle activity and thus the risk of RSI and carpal tunnel syndrome.
A too large slanted angle will again result in higher muscle activity and thus increase risk. On top of this it has been shown that continuous low intensity muscle activity may damage the finer muscle tissue, also known as the cinderella effect.
Field research has shown that the ideal, slanted HandShoe Mouse fulfills all ergonomic requirements as concluded from the world wide, extensive, university based research.
