With the spotlight shining on ergonomics issues lately, the modern
workplace has been labelled as "dangerous" by the press.
Today's office workers-manning the new frontier in wired skyscrapers
and small businesses-are learning the hard way about work-related
health disorders.
An office worker can spend anything from 25 to 40 hours a week
in a static position working at a computer. Travelling to and from
work may involve long journeys either sitting (or more likely standing)
on a train or bus with no room for movement. When we get home, it
is far easier to sit and eat dinner in front of the TV, spending
the rest of the evening sprawled on the sofa, than it is to go out
and get some exercise.
Back pain is one of the most common work related health problems
– yet it can be easily prevented by ensuring that your working environment
is back friendly. In the United Kingdom the charity BackCare estimate
that back pain and related illness cost industry $10 billion annually
through absenteeism.
The modern workplace is full of new ergonomic dangers and pitfalls
that call for pioneering safety measures. Just as the new technology
of the information place is a source of these dangers, it is also
part of the cure. Telephone headsets, such as the ones manufactured
by Plantronics, Inc., are a prime example of a safety enhancement
accessory that should be incorporated into the modern office environment.
Once worn only by telephone operators back in the 1950s, headsets
are finding their way into offices across the world, and with good
reason. Headsets are known to add many advantages to the workplace.
According to a Santa Clara Valley Medical Study, headsets reduce
neck, upper back, and shoulder tension by as much as 41 percent.
An additional study by H.B. Maynard & Co., Inc. concluded that
adding hands-free headsets to office telephones improved productivity
by up to 43 percent. Headsets are also known to reduce the chances
of work-related physical disorders, specifically injuries of the
neck and upper body, resulting in reduced workers' compensation
costs.
“Unlike manual worker safety, the issue of occupational injury
among office staff is still not taken seriously enough by employers”,
said Elizabeth Simpson MCSP, SRP at the European Institute of Health
and Medical Sciences . “This is partly because the injuries caused
by bad telephone habits cannot be seen and take time to manifest.
Research has shown that the use of telephone headsets can reduce
neck pain, back pain and headaches in subjects who use the phone
and computer simultaneously for a minimum of two hours a day.”
Telephone Handsets and Demands on the Neck
It is in the use of the telephone handset that the most significant
work related disorders of the neck could occur. When the seemingly
simple act of squeezing the handset against the shoulder and neck
is performed routinely, or held for long periods of time, anything
ranging from discomfort to structural tissue damage can occur.
The use of telephone headsets is beneficial for improving head
and neck postures. With the freedom a headset provides, awkward
and prolonged static postures of the head, neck and shoulders can
be avoided. In an even greater sense, the freedom offered by hands-free
movement allows workers extra mobility, reducing static loads on
the entire body, and potentially contributing to greater worker
comfort and productivity. Headsets also are known to alleviate stress
on the neck for all-day users, as well as for those who use the
telephone sporadically throughout the day.
Upper Body Disorders
Upper body disorders, medically referred to as "musculoskeletal
disorders," represent a variety of problems involving repetitive
stress injuries of the tendons, muscles, nerves and supporting structures.
They can range in severity from occasional to frequent, or from
annoying to debilitating.
The disorders of the upper body and extremities have been studied
for many years. Most often, such studies have focused on the arms,
hands, wrists, shoulders and elbows. Literally volumes have been
written regarding the specific disorders associated with these body
parts, i.e. carpal tunnel syndrome in the wrists, epicondylitis
in the elbows, DeQuervains disease in the hands, just to name a
few.
Fewer, but not less important, studies have addressed the symptoms
associated with the neck experienced by workers performing repetitive
job functions. The simple truth is that the same work exposures
that affect the upper body also can affect the neck. Work exposures
such as awkward postures and repetitive movements have been linked
to disorders of the neck; disorders that are no less serious than
those involving the hands, wrists or elbows.
A recent publication of NIOSH (1997) reviewed more than 230 research
studies of work- related disorders of the upper extremities. Among
these studies, 89 of them included investigations of work factors
relating to disorders in the neck and shoulders. The review committee
for this publication concluded that there was "strong evidence
that high levels of static contraction, prolonged static loads or
extreme working postures . . . increased the risk for neck and shoulder
musculoskeletal disorders."
A Call for Awareness
Although awareness in the information place is growing, it lags
behind the need to holistically revolutionize the modern workplace.
Because of the extraordinary rate of change in technology, health
problems often set in before the potential usage dangers are realized.
In effect, employers, healthcare providers, physical therapists
and employees can be blind-sided when staffers are physically impaired
on the job site. The prescription: set the right direction to reduce
the risks to workers by doing tasks more effectively with the proper
tools, and provide the appropriate training and education so workers
can use new technologies safely.
