Click. Drag. Double-click; lift the mouse off the edge of the desk, rinse, and repeat. All day, every hour, hours on end, weeks to years...have you considered the enormous burden computing and typing have placed on your, and your employees', physiologies?
Simply put, the human body was not designed to do the same exact motion for hours on end, everyday for years. This is a recipe for failure - and fail we do! But you may not even be aware of it.
Suffering myself from a form of RSI or Repetive Strain Injury, I can tell you it is a job-killer - and your people may be too embarassed to even speak out! Why it's embarassing goes to the American motto we all cling to: "We get 'er done!" But this motto exacts a heavy toll on our bodies if we cling to it too tenaciously.
Over time with repetitive motions, the muscles and tendons of the wrist, arm, and even upper body become inflamed, sore, and cause a very real and painful condition that can require drugs, surgery, or even cessation of computer work. In short, it's a real problem and it's bound to show up, recognized or not, in your workforce. Consider that this is most likely occurring at your place of business, whether you know it or not.
The first thing is to raise awareness that some folks may be having the problem - and provide a safe and confidential way for them to let you know they are having an issue.
Besides medical attention, these RSI sufferers could benefit from one terrific simple change: introduce a high quality trackball instead of a mouse. Although not perfect, trackballs go a tremendously long way in relieving RSI pain and increasing productivity.
In a trackball, look for a large heavy ball that rotates smoothly. Don't bother with the cheap small ones; get high quality.
Keep in mind many employees fight trackballs at first, so be firm about them trying them out for a few weeks. Although most people grow to love a trackball, some folks simply never do; you can offer other input devices for the stubborn ones. Possibilities include alternatively-styled trackballs, trackpads, or if you must, try a better or different mouse.
Other key factors in alleviating this issue are wrist rests, proper chairs and desks, proper lighting and frequent breaks.
I hope you feel inspired to raise awareness and take some simple but effective actions for your RSI sufferers. Remember, you probably have people suffering with this issue whether you know it or not.
