3M has announced the availability of its new "Ergonomic Mouse" that it says is clinically proven by the Centre for Ergonomic Research, Miami University and the University of Oslo, to reduce muscle strain.

The 3M Ergonomic Wireless Optical Mouse can help reduce the discomfort associated with carpal tunnel syndrome and repetitive strain injury, says the company.

With joystick looks, the mouse offers a vertical ergonomic grip, therefore encouraging the wrist to remain locked, apparently reducing the pressure on the median nerve and keeping arms and shoulders in a more relaxed, neutral position.

The mouse is compatible with Windows XP and up, and Apple and Mac OS 10 X machines and is on sale now priced from £143.92.
