Contour Perfit Optical Mouse LEFT
Does Using the Computer Mouse with Your Left Hand Hurt? Here's the Perfect, I mean "Perfit" Solution! Contour Perfit Optical Mouse: The Contour Perfit Optical Mouse the latest generation of the Award Winning Contour Perfit Mouse. The Contour Perfit Optical Mouse maximizes comfort and ease due to the extraordinary fit this computer mouse provides. The biggest advantage of the Contour Perfit computer mouse is the multiple size options for both the right nad left hand. You can choose the size that best fits your hand size, therefore eliminating pain, excessive strain and fatigue that may occur with a poorly fitted mouse. Many computer users complain of pain or experience computer-related injuries due to the fact their mouse does not fit their hand well, the Perfit mouse solves that problem! The Contour Perfit Mouse is somewhat unique in that it comes in a variety of sizes - five right-handed versions and three left handed versions - which Contour claims offers performance and ergonomic benefits that simply can't be achieved by any "one size fits all" mouse. The Perfit mouse is available in extra-small, small, medium, large, and extra-large for the right hand and small, medium and large for the left hand. It is designed to fit the hand so precisely that multiple sizes are necessary to maximize the total impact of the ergonomic design. The Perfit Mouse is also designed to minimize biomechanical load and reduce hand and arm deviations from the neutral pronation position. The mouse's top surface is contoured to fit the palm of the hand to disperse pressure across the palm during use, and the thumb side of the mouse is higher than the other to minimize pronation strain. There is also a support provided for the thumb, which allows movement of the mouse with reduced Pinch Force, which is known to increase the risk of Carpal Tunnel Syndrome. The prescribed way to use the Contour Perfit Optical mouse is to lay your hand more or less flat on top of the mouse, with the weight of your hand and arm resting on your palm, your fingers together rather than spread, with your index, middle, and ring fingers resting lightly on the Contour Perfit Mouse's three buttons. The buttons are elevated and shaped to reduce load on the fingertips. The elevated wrist support reduces pressure on the wrist by keeping it off the desktop, maintains a straighter wrist alignment, minimizes lateral deviation, balances the hand in a neutral, tilted posture, and prevents static grip by allowing the hand to rock freely. This posture allows mouse clicking pressure to come mainly from the whole finger being depressed from its base joint, which, once you get used to it, begins to feel quite correct and natural, as well as less stressful on the muscles of your fingers and wrists. Research Proven: A research study, entitled "Ergonomic Test of Two Hand-Contoured Mice." conducted by Wanda Smith, Bob Edmiston, and Dan Cronin of Global Ergonomic Technologies, Inc. in Palo Alto, California, tested the Contour Perfit Optical Computer Mouse in a shootout with the Microsoft Ergonomic Mouse. At the end of the test, participants in the study were asked to rate, on a seven point scale, 27 usability, comfort, and design features of each mouse. The Contour Perfit Mouse came out on top in 21 of the 27 categories and was rated "significantly better" in six categories. In nine comparative features ratings evaluated, the Contour Perfit Optical Mouse was rated "best" in eight catgories and "significantly better" in four. The researchers summarized: "In this study, the Contour Perfit computer mouse resulted in significantly less overall muscle effort than the Microsoft mouse for most of the test tasks. Finger abduction and ulnar deviation resulted in the highest muscle effort - almost twice that for hand extension and arm pronation. The average muscle effort for finger abduction, ulnar deviation, and arm pronation during Contour Perfit Optical computer mouse use was significantly less than muscle load during Microsoft mouse use. In conclusion, this study appears to demonstrate that the Contour Perfit Optical mouse met its design objectives of reducing biomechanical load and discomfort compared to the most commonly used ergonomic mouse without sacrificing user performance." Yet another research study entitled "A Joint Labor/Management Comparative Study of Various Non-Keyboard Input Devices in a Call Center Environment," by US West's Corporate Ergonomist, Jim Stewart and the Communication Workers of America's occupational safety and health director, David LeGrande, was presented at the 3rd Annual Applied Ergonomics Conference held in Los Angeles, California. The ergonomic benefits of the Contour Perfit Mouse, Cirque Touchpad, and Logitech Mouseman were evaluated in this six week study conducted at the Albuquerque US West site. "A total of 66 subjects entered the study, and 61 completed all four phases of the study." According to Stewart's research, "The Contour Perfit optical computer mouse groups responded most positively during the study period, including a positive assessment of smoothness of general effort required, accuracy and ease of use." Also, the Contour Perfit Computer Mouse had the best ratings in "Comfort", "Ease of Use", "Accuracy", "Feel" and "Ease of Position" categories examined. Some of the findings showed a 48% reduction in pain after 3 weeks of using the Contour Perfit Mouse compared to the original "Control" device, which was the Logitech Mouseman. The Contour Perfit Mouse users post-study results showed an increase in pain of 37% after taking the Contour Mouse away and giving the users back the "Control" device for a four week period. Award-Winning! Contour's Perfit Mouse was also voted "The Best Ergonomic Product" at an exhibition of ergonomics products at the 13th Triennial Congress of the International Ergonomics Association in Tampere, Finland, where top ergonomists from all over the world came together to share their knowledge and experiences.
