For many individuals the early symptoms of CTS go unnoticed. Employers and co-workers can help one another identify the onset of CTS by watching for and pointing out any unconscious shaking of the hands, rubbing of the wrists, or unusual postures or hand positions at the keyboard.
At the first sign of CTS, you should be examined by a doctor who specializes in hand and wrist disorders. The doctor can perform a number of simple tests to detect CTS, and can prescribe specific steps for avoiding the problem.
Summary
Carpal tunnel syndrome is common among computer keyboard users. It can strike anyone, and its consequences are serious. Awareness of the problem and its causes is crucial to preventing CTS. With proper ergonomics and attention to the work routine you can prevent CTS; with early detection and treatment it need never become debilitating. The employer's attention to stress levels, proper ergonomics, and the early warning signs of CTS are important in keeping the ailment at bay in the workplace.
Summary
We hear a lot about hazards associated with working with computers, and learn from experience that long hours at the keyboard can bring on eyestrain and various aches and pains. These concerns, and the steps we can take to make computer work safer
and more comfortable are the subject of many books and articles.
The good news is that problems can be avoided through well-designed offices, properly set-up workstations, and sensible work habits. Checklists and guidelines for setting up and using computers abound. The bad news: there is substantial variation in opinion as to what constitutes proper workstation set-up, quick and easy solutions to ergonomic problems are not always possible, and checklists don't capture the complexities of the possible combinations of people, task, equipment, and workspace. Fortunately, there are measures that really do work. A few quick and universally agreed upon precautions:
Use the minimum force necessary to press the keys.
Vary your tasks during the day to avoid sitting in one position for several hours or performing the same hand motions without interruption.
Take periodic breaks.
Keep your wrists in a natural, unforced, straight position.
