If you like the EZ MiniCute Mouse, you'll love the IG UserNomic. The IG UserNomic Mouse is a vertical style ergonomic mouse that eliminates forearm twisting. The placement of the thumb scoop allows users to maintain an anatomically neutral position with no pre detirmined thumb position. Designed to eliviate the symptoms associated with MAS (mouse arm syndrome), a form of repetitive strain injury, the IG UserNomic Mouse puts the hand in a relaxed position with the fingers flexed half way between a fist and completely straight. This balances the tension between the flexors and extensors of the fingers reducing the potential for muscle, tendon and nerve damage.
