Comparison Of Ergonomic Mouse

The document evaluates 8 ergonomic computer mice and a regular mouse by measuring muscle activity via EMG. It finds that most mice lead to high extensor and flexor muscle loads due to forcing the hand into unnatural positions that require gripping or hovering. Only The Horse mouse provides full hand support and a shape that allows fingers and thumb to rest in a relaxed position, minimizing unnecessary muscle exertion according to EMG measurements.
