Abstract:
Construction work has recently been an area of focus in terms of programs
to reduce work-related musculoskeletal disorders (WMD). In an attempt to
begin to define where interventions would have the greatest benefits, a
survey tool was used in the U.S. and Slovakia to determine self reported
prevalences of WMD and related job factor perceptions. Responses were obtained
from nearly 300 Slovak unionized equipment operators and nearly 400 U.S.
unionized operating engineers. Results of the investigation indicate considerable
similarity between both symptom prevalence and job factor perceptions across
both countries. However, significantly more Slovak equipment operators
reported missing work due to WMD than did their U.S. counterparts. A difference
which may be attributed to the absence of “sick days” among U.S. operating
engineers. In addition, the U.S. operators reported considerably more work-related
hand and wrist symptoms and considerably fewer upper back symptoms than
their Slovak counterparts. Both of these differences are most likely due
to differences in equipment control design and layout. When comparing percentages
of operators visiting physicians, there were very few differences. In general,
perceptions of the work environment between the two groups were quite similar.
Differences noted included considerably greater problems with the use of
tools with design problems among Slovak operators and considerably greater
problems related to working at or near their physical limits, bending or
twisting their back in an awkward way and reaching overhead or away from
their body among U.S. operators. This evaluation and comparison has provided
insight into cultural, equipment and work organization differences. In
both the U.S. and Slovakia, the data obtained should allow more focused
and productive ergonomic interventions within the profession of construction
heavy equipment operators.
