The results of the video analysis are shown in Table 3. For
155 cm subject height was comfortable at 70 cm in the neutral
zone posture showing shoulder joint was abducted at 15 degree
and elbow joint showed extension at 125 degree abduction of
wrist joint.
At 65 cm OR table height there was less comfort experienced
by the subject as the shoulder joint was abducted to zero degree
and the elbow joint extended to more than 130 degree (i.e.
150 degree). On further raising the table height to 75 cm there
was the same less comfort. The shoulder joint was abducted to
40 degree with extension of the elbow joint to 120 degree to
perform the task.
When the OR table height was further raised to 85 cm there
was discomfort experienced by the subject since the abduction
of shoulder joint had increased further to 45 degree combined
