Cumulative disorders are a rising occupational hazard


December 24, 1990|By Michael Enright | Michael Enright,Special to The Sun

In the old days, the term "occupational hazard" conjured up images of a helmeted construction worker balanced at the peak of an unfinished building as a menacing swinging steel girder was lowered into place.

In today's workplace, the obstacles to a healthy office environment may not be as obvious or dangerous as a falling brick or a collapsing mine shaft, but they are certainly more commonplace and, in some cases, just as debilitating.

Everywhere you look in the modern office or workshop lies the potential for an illness or accident -- from desks and chairs that are too high or too low to poorly arranged computer keyboards and inferior tools. Statistics show that

poorly designed workstations or desks often result in problems with an employee's musculoskeletal system, particularly in women and elderly workers.

In November, a Bureau of Labor Statistics survey found that employers reported 6.6 million occupational injuries and illnesses in 1989, about 136,000 more than were reported the previous year.

But perhaps most alarmingly, the survey shows that in the Automated Age, where more and more tasks are broken down into repetitive, assembly-line jobs, there has been an explosion in the number of repetitive trauma cases. In 1981, the BLS reported that 18 percent of reported occupational illnesses were disorders associated with repetitive trauma. Last year,

the figure was 52 percent.

And repetitive trauma -- instances of occupational illnesses caused by repeated motion, pressure or vibration -- shows no signs of abating any time soon, according to doctors, ergonomists and labor experts.

"This is a growing problem with no end in sight," said Louis Slesin, the editor of VDT News, a New York City-based compute

newsletter. "Better equipment and training is the solution, along with changing work habits, but industry isn't going to like it one bit."

Several experts on ergonomics -- the study of the worker in the workplace -- stress that there is no "magic bullet" to cure all office ailments resulting from cumulative trauma disorder or repetitive

stress; there are, however, several precautions and treatments that employers should consider to eliminate or minimize these problems:

Better equipment: The advice here is basic -- chairs, desks, computers, printers, facsimile machines, etc. should be user-friendly instead of forcing the worker into contortions just to operate them.

Adjustable chairs are a must in the modern office. A person who regularly uses a keyboard or typewriter should be positioned so that their elbows are roughly even with the typing panel. Shorter workers should have access to a footrest that can be placed under their desk and prevent their feet from dangling for long periods of time.

Just as a good schoolteacher admonishes a student for poor posture, a conscientious employer who has provided his or her employees with quality work equipment should make sure workers are using it properly.

Employees can become very comfortable sitting or typing in awkward positions, doctors and physical therapists say -- that is, until they suddenly find themselves with a painful backache, bursitis or tendinitis. Employers may not want to be as upfront as the schoolteacher about poor posture, but some tactful reminders about sitting up straight pinned to the office bulletin board may help.

Doctors and physical therapists say they are always seeing patients whose telephone-handling skills have left them with sore necks and shoulders. The telephone should not be squeezed between the head and your shoulder; a telephone headset should be provided for workers who need to use their hands and the telephone simultaneously. Also, computer terminals that are placed to either side of the desk, instead of directly in front of the user, can cause neck strain.

The glare from video display terminals should be reduced according to each person's preference. Some ergonomists recommend that employers have new employees' eyes checked before hiring to determine any potential problems. The tilt of a VDT can also cause neck and eye strain.

Employers in workshops might reduce the size or weight of a load in a repetitive job task or provide armrests to better absorb the weight. To keep word processors' wrists from resting too low on the keyboard, padded edges can provide a comfortable lift.

Monitoring: Just as any good business manager or owner watches his production output, so must they oversee working conditions and those areas of the business where illnesses and physical complaints occur more often.

"Treat every single case as if it were real," says Bob Bettendorf of the Institute for Office Ergonomics in Stamford, Conn. "The possibility that the problem occurred elsewhere or isn't there at all exists, but don't dwell on it because drawing attention to it probably won't help you or the employee."

Monitoring can also accurately assess the incidence of the disorder, the employees most likely at risk, and the preventive measures best suited for a problem.
