Individuals working at
microscope workstations often report experiencing discomfort in
their necks, shoulders, lower backs, and wrists. A logical result
of this is that these individuals have difficulty maintaining their
concentration and productivity levels suffer. JAN has received many
requests for accommodating individuals who use microscopes at lab-type
workstations and has come up with the following accommodation suggestions:
First, determine whether
the workstation is adjustable and fits the worker. Products used
to make a workstation adjustable include tables, desks,
and ergonomic
and forward-leaning
chairs. Adjustability is especially important for workstations
that are multi-user stations. Corner
cushions help eliminate punctures from sharp corners and forearm
supports compensate for the lack of upper body support.
Second, manufacturers
produce microscopes that are adjustable to the user. These are
called ergonomic
microscopes. Static postures typically occur when the user
leans over to observe specimens. Over a period of time, this leaning
may lead to neck pain and lower back discomfort. Manufacturers
also have addressed the fine motor movement and wrist posture
necessary to adjust microscope knobs. Handle build-ups and microscope
headrests on existing microscopes may be other effective alternatives.
Third, many microscopes
can be retrofitted with a personal computer (PC) and digital imaging.
Products are also sold as integrated units called PC
scopes. Controls for the microscope are handled through the
PC. Alternative input devices may be used by the operator depending
on the individual’s functional limitations. Links to these
products can also be found below.
Questions to consider
when evaluating a microscope workstation include:
What type of applications
are needed? Microscopes are specialized to the industry. Typical
ones are medical research, manufacturing inspection, petrol-geology,
and micro-surgeries.
Is the workstation
used by multiple users? If so, adjustable
workstations should be considered. If not, adaptations may
be made to fit a single user.
What are the areas
of discomfort reported by the workers? Training of proper postures
along with the above mentioned products may be needed. Workers
should also be encouraged to take appropriate work and stretch
breaks to reduce fatigue.
