WORK RELATED INJURIES
Work-related
musculoskeletal
disorders
(WMSDs)
are
a
group
of
painful
disorders
of
muscles,
tendons,
and
nerves.
Carpal
tunnel
syndrome,
tendonitis,
thoracic
outlet
syndrome,
and
tension
neck
syndrome
are
examples.
Work
activities
which
are
frequent
and
repetitive,
or
activities
with
awkward
postures
cause
these
disorders
which
may
be
painful
during
work or at rest.
Almost
all
work
requires
the
use
of
the
arms
and
hands.
Therefore,
most
WMSD
affect
the
hands,
wrists,
elbows,
neck,
and
shoulders.
Work
using
the
legs
can
lead
to
WMSD
of
the
legs,
hips,
ankles,
and
feet.
Some
back
problems
also
result
from repetitive activities.
WMSDs
are
very
difficult
to
define
within
traditional
disease
classifications.
These
disorders
have
received
many names, such as:
•
Repetitive motion injuries.
•
Repetitive strain injuries.
•
Cumulative trauma disorders.
•
Occupational cervicobrachial disorders.
•
Overuse syndrome.
•
Regional musculoskeletal disorders.
•
Soft tissue disorders.
Most
of
the
names
do
not
accurately
describe
the
disorders.
For
example,
the
term
"repetitive
strain
injuries"
suggests
that
repetition
causes
these
disorders,
but
awkward
postures
also
contribute.
These
terms
are
used
synonymously,
and
in
the absence of agreement, WMSD is used in this document.
WMSDs
are
recognized
as
leading
causes
of
significant
human
suffering,
loss
of
productivity,
and
economic
burdens
on
society.
The
data
available
are
limited
and
does
not
represent
the
magnitude
of
the
problem
because
there
is
a
great deal of under-reporting of these types of injuries.
WMSDs
arise
from
ordinary
arm
and
hand
movements
such
as
bending,
straightening,
gripping,
holding,
twisting,
clenching
and
reaching.
These
common
movements
are
not
particularly
harmful
in
the
ordinary
activities
of
daily
life.
What
makes
them
hazardous
in
work
situations
is
the
continual
repetition,
often
in
a
forceful
manner,
and
most
of
all,
the
speed
of
the
movements
and
the
lack
of
time
for
recovery between them.
WMSDs are associated with work patterns that include:
•
Fixed or constrained body positions.
•
Continual repetition of movements.
•
Force
concentrated
on
small
parts
of
the
body,
such
as
the hand or wrist.
•
A
pace
of
work
that
does
not
allow
sufficient
recovery
between movements.
Generally,
none
of
these
factors
acts
separately
to
cause
WMSD.
WMSDs
commonly
occur
as
a
result
of
a
combination
and interaction among them.
Heat,
cold
and
vibration
also
contribute
to
the
development
of WMSD.
Pain
is
the
most
common
symptom
associated
with
WMSDs.
In
some
cases
there
may
be
joint
stiffness,
muscle
tightness,
redness
and
swelling
of
the
affected
area.
Some
workers
may
also
experience
sensations
of
"pins
and
needles,"
numbness,
skin colour changes, and decreased sweating of the hands.
WMSDs may progress in stages from mild to severe:
•
Early
stage:
Aching
and
tiredness
of
the
affected
limb
occur
during
the
work
shift
but
disappear
at
night
and
during
days
off
work.
No
reduction
of
work
performance.
•
Intermediate
stage:
Aching
and
tiredness
occur
early
in
the
work
shift
and
persist
at
night.
Reduced
capacity
for
repetitive work.
•
Late
stage:
Aching,
fatigue,
and
weakness
persist
at
rest.
Inability to sleep and to perform light duties.
