Ergonomic factors
RULA: The mean wrist score of 2.3 indicates
that the wrists of employees were in extension
(sagittal plane) of up to 151 in both observations.
The mean neck score of 1.9 means that the necks
of the population were in either flexion, rotation,
or side bending. The final mean RULA score of
4.5 indicates that the employees’ postures at their
workstations need to be investigated further and
altered in some cases. There were no employees in
the Hi-Tech company who received RULA scores
of 1–2, which indicates an acceptable posture. The
final RULA score ranged from a minimum of 3 to
a maximum of 6.5 (see Fig. 2). The mean arm/wrist
RULA score was identical in men and women
