Ergonomics

How we can help

If RSI symptoms are already present, there are various things that can be done to reduce the severity of the symptoms. The easiest and cheapest solution is to apply the proper ergonic methods mentioned on the first page. A proper work environment and frequent breaks from repetitive actions can go a long way toward reducing the symptoms. Another huge stress relief comes from using the proper tool that is already designed with ergonomics in mind. Many of the products produced by ITAC Systems are just such tools.

The use of computer mice is a growing source of lost productivity, paint, and even injury, in the computer workforce today.

The Constant gripping, motion involved and pressing of buttons with fingers better suited to fine motor control is a daily contributer to repetivie stress injuries.

The mice that are shipping with computers today can contribute to injuries that range from calloused hands and wrists to loss of use in the hand. If fact, recent tests indicate that computer mice may greatly contribute to the growth of RSI, particularly amongh graphic artists and CAD engineers who use the mouse heavily to perform grahics-intense applications on a daily basis.

How can mice be so potentially harmful? There are 2 primary reasons for this:

• Shape: The shape of an ordinary mouse requires the user to grip and hold, which, over an extended period, will cause tendon and muscle fatigue in the hand and wrist.
• Motion: The side to side swaying motion used to propel the cursor around the screen has been linked to several injuries, including tendinitis and friction burns from contact with the mouse pad.

One very effective alternative to the problems of a mouse is a computer trackball. These devices elimiate the need for constant arm motion and wrist flex.

The MOUSE-TRAK Alternative

The MOUSE-TRAK trackball makes comfort, productivity and ergonomics top priorities. The MOUSE-TRAK trackball was designed specifically for power users and heavy use environments. MOUSE-TRAK provides an ergonomic alernative to common mice and commodity trackballs.

MOUSE-TRAK allows the hand and arm to remain in a natural resting position during operation.

There are no unnecessary movements such as those required to use a mouse

The middle fingers are used to rotate the ball, keeping them free from button pushing that can lead to tendinitis

Buttons are placed in the ergonomically correct 3, 6 and 9 o'clock positions are are easily reached and controlled.

Ball movement force is reduced through the use of precision stainless steel ball components
