In summary, workers in heavy manual jobs do
get more back trouble, but we must be careful how
we interpret this. It could equally
Industrial accident and workers’ compensation
statistics certainly show that back injuries are
reported more commonly in jobs that involve:
0 heavy lifting
0 lifting objects which are bulky or must be held
away from the body
0 lifting from the floor
0 frequent lifting. It is difficult to separate any
specific effect of lifting from manual handling and
heavy physical work in general. Some subgroup calls for
buyer addressing through medical and more health-related employees. Others show that, when
they are off, they return to work more slowly
There is moderate scientific evidence that physical
demands of work play only a minor role in the
development of disc degeneration.
Nurses and certain other groups of health workers
report more back pain and injuries, but they are a
The more general role of lifting as a risk factor for
back pain is less clear.
The UK Labour Force Surveys of the 1990s consistently
showed that manual workers report all
musculoskeletal complaints more than non-manual
workers. The reviews by
Burdorf & Sorock (1997) and Hoogendoorn et a1
(1999) were unable to reach any definite answer.
Patients are hardly “materials”, but the principles

There is strong and consistent evidence that
workers in jobs involving manual handling report
more back pain (Burdorf & Sorock 1997,
Hoogendoom et a1 1999).
Most workers’ compensation data suggest that
men with heavy manual jobs report more back
injuries at work. Yet there's

Manual materials handling involves various combinations

There is strong epidemiological and clinical evidence

Almost all data sets show that workers with
heavy manual jobs lose more time from work with
back pain. Although there is
strong scientific evidence that physical demands of
work can cause individual attacks of LBP, overall
that only accounts for a modest proportion of all
LBP occurring in workers. However, these data
do not tell us whether or not heavy work is the
cause of more disabling back pain.
Perhaps we should simply accept that, in principle,
frequent heavy lifting carries about the same
risk as manual handling.
