The vertebral column of the ground-sitting
workers looked like bow, as they had to bend
their backs to get a closer proximity of the
products to their eyes. That could have impact
on the lower discs of the vertebral column [8].
Therefore, feeling of discomfort in lower back
of the workers sitting on ground (Category C)
was higher than other two categories
(Category A and B). Having been bent
forward and leaned constantly, extra pressure
was imposed on the waist. That was also due
to stiffness and least movement of waist
region [10-11,28], which led to cause more
pain in the workers sitting distantly from their
area of operation (Category B). However,
there was little deviation of feeling of pain
between those three groups and pain was
slightly more in Category B from the
Categories C and A. The workers who used to
sit on the ground had acquired specific type of
postures, either squatting or kneeling or just
sitting cross-legged. Movement of legs was
not possible in those specific types of postures
as well as in-sufficient work place layout.
Therefore, circulation used to get interrupted
by pressure and fluid could accumulate in
those regions leading to pain. Pain in the knees as
well as ankles were reported to be slightly higher
in the workers belonged to Category C. However,
in case of feeling of discomfort in knee and ankle
did not significantly differ between the three
categories. Persons sitting on high platform or
standing on ground for long time might also
suffer from those problems, as there were also the
possibilities to accumulate metabolites in those
lower proximities.
