EFFECTS OF
AWKWARD POSTURE
AWKWARD POSTURES
High Task Repetition
Many work tasks and cycles are repetitive
in nature, and are frequently controlled by
hourly or daily production targets and work
processes. High task repetition, when
combined with other risks factors such high
force and/or awkward postures, can
contribute to the formation of MSD. A job is
considered highly repetitive if the cycle
time is 30 seconds or less.
What is awkward posture?
"Awkward posture refers to positions of the body
that deviate significantly from the neutral
position while performing work activities. When
you are in an awkward posture, muscles operate
less efficiently and you expend more force to
complete the task."
By Natashatul Aisyah binti Maslan (4171003021)
Khiranraj a/l Pichamuthu (4171004311)Many work tasks require high force loads
on the human body. Muscle effort increases
in response to high force requirements,
increasing associated fatigue which can
lead to MSD.

RISK FACTORS
Forceful Exertions
Repetitive/Sustaine
d Awkward Postures
Awkward postures place excessive force on
joints and overload the muscles and
tendons around the effected joint. Joints of
the body are most efficient when they
operate closest to the mid-range motion of
the joint. Risk of MSD is increased when
joints are worked outside of this mid-range
repetitively or for sustained periods of time
without adequate recovery time.
CONTROL MEASURES
Work Practice
Controls
Job Rotation
Eliminating excessive force and
awkward posture requirements will
reduce worker fatigue and allow high
repetition tasks to be performed
without a significant increase in MSD
risk for most workers.
Providing safe & effective procedures
for completing work tasks can reduce
MSD risk. In addition, workers also
should be trained on proper work
technique
Workers can rotate between
workstations and tasks to avoid
prolonged periods of performing a
single task, thereby reducing fatigue
that can lead to MSD.
Proper Body
Mechanics
Workers should be trained to use proper
lifting
