You will need to make an assessment of posture for five body parts:
A similar two-step approach is used to assess the posture of each body part. With regular use of ART, it is likely you will become familiar with this approach and will not need to refer to the assessment guide as often.
Determine whether the body part is placed in an awkward posture when performing the task. If the posture is awkward, then determine the amount of time that the posture is awkward.
|If the posture is not awkward, the colour is Green.|
|The colour is Amber if the posture is awkward for a part of the time (i.e. 15-30% of the cycle time).|
|The colour is Red if the posture is awkward for more than half the time (i.e. more than 50% of the cycle time).|
It is possible to use intermediate scores if the factors you are assessing falls between two categories (e.g. if the posture is awkward for about 40% of the cycle time)
More tips are provided towards the bottom of this page to help assess worker posture.
The neck is considered to be bent or twisted if an obvious angle between the neck and back can be observed as a result of performing the task.
The back posture is considered awkward if more than 20° of twisting or bending is observed.
The left image shows about 20° of forward bending.
The arm is considered to adopt an awkward posture if the elbow is raised to around chest height and the arm is unsupported (e.g. not resting on a workbench).
The wrist is considered to be bent or deviated if an obvious wrist angle can be observed.
Identify any awkward pinch grip or wide finger grip used during the task. This factor can be scored Green if the task involves use of a power grip, or a loose grip that the workers does not consider awkward.
This is a good time to ask the workers whether they feel any discomfort or cramping in the hands when gripping tools or work pieces.
