The Microsoft Natural Ergonomic Keyboard 4000 is one of the best-selling wired ergonomic keyboards in the United States.  Users report improved typing comfort and reduced risk repetitive typing injuries.  The Microsoft Natural Ergonomic Keyboard 7000 delivers the same features in wireless technology.  However, many people use the mouse up to 3 times as often as they use the keyboard.  Now, Microsoft has added the Natural Wireless Laser Mouse 6000 to its “Natural” line of products. 

“Natural” defines the placement of the hand, wrist and forearm in the positions that are the least stressful and the least awkward while typing.  This is important because stressful exertions, awkward positioning and repetition are three of the main factors for the development of a repetitive strain injury such as carpal tunnel syndrome or tendinitis.

The Natural Mouse features a more spherical shape than the traditional mouse.  It is also taller so that it fits the shape of the relaxed hand.   These features promote a more vertical alignment with the forearm in a more neutral position (the “handshake” position) relieving stress on the tendons and nerves at the wrist.

Mouse features include: 2.4 GHz wireless technology with up to 30 feet of wireless range; 4-way scrolling; a point and click magnifier; a 6 month battery life with a battery life indicator; high definition laser technology; an instant viewer using the scroll wheel; and 5 customizable buttons that can be programmed to do a variety of functions. The retail MSRP for the Natural Wireless Laser Mouse 6000 is $79.95.

Wireless Mousing Tips:  You can lighten the Natural Mouse by removing one of the batteries.  Although the charge will last only about half as long, the mouse will perform all of its normal functions with less overall weight.  When using the mouse, it is important not to swivel at the wrist (keep the wrist straight and move through the forearm) and not to squeeze the mouse tightly (use the lightest grip possible while still giving you control).
