Though the AlphaGrip has not undergone the extensive testing necessary to definitively claim that it is an ergonomic device, there are certain aspects that appear to make it more ergonomic than a standard keyboard and mouse. See what one customer said about the ergonomic benefits of AlphaGrip below.
- When holding an AlphaGrip, your hands are in a vertical orientation which is more ergonomic than the horizontal pronated hand position associated with typing on a standard keyboard.
- The AlphaGrip also requires less finger movement than that required on a keyboard to generate the same amount of text (see University of Utah graduate student Scott Rodgers' finger travel study.)
- With its thumb-controlled trackball, the AlphaGrip minimizes hand and arm movement as compared to a mouse which requires users to hold their hands up on a desk and out to the side.
- A recent study indicates that sitting up straight at your desk at a 90% angle (the widely recommended posture for using a keyboard) is responsible for many back problems, and that it is healthier to lean back at a 135% angle, which is the preferred position for an AlphaGrip user (see article, New Advice, Don’t Sit up Straight, by Sara Goudarzi on LifeScience.com).
- An AlphaGrip user can change his body position while continuing to work on his computer thus relieving the stress that accumulates from typing from the same position over a long period of time.
