Also, almost all the respondents (94%) used a static
chair in their workplace while only a few used a
rolling/moveable chair.
This could be a possible reason
for the occurrence of pain — especially low back pain.
Our finding is in agreement with previous studies
(Gradjean, 1981; Green & Briggs, 1990).
Ortiz-
Hernandez et al (2003) reported that maintaining
fixed positions for a long time causes “Tingling in
extremities”.
Green & Briggs (1990) had reported that
a static sitting position for extended hours increases
intradiscal pressure, disc degeneration and poor disc
nutrition, and this may be related to the reported back
pain. Also, only a few respondents (6.9%) reported
using height adjustable chairs in order to ease their
view of the VDU and balance their posture.
