Due to continous working in one position computer operators are at greater risk of sustaining various repetitive stress injuries.To avoid these risk u should follow a good ergonomic design of work place.
the above figures shows how one should follow it :-
1)the seat of the chair should be of proper height with a back rest and arm rest.The height of arm rest should be at the level of elbows;when arms kept side of body with elbow flexed if armrest is available or can keep free and straight as shown in figure.
continous working without the forearm supported risks supraspinatus tendinitis.
2)The monitor should be in level with the eyes.Monitor above eye level compels the operator to adopt a chin forward posture.
chin forward posture in due course leads to cervical spondylosis.
3)The wrist should be in neutral position.This requires proper wrist support
and proper height adjustment of the keyboard.
Improper positioning of wrist risks carpal tunnel syndrome.
4)The keyboard should be 10cm at away from the edge of the table to allow the support to the wrist.
5)Monitor should be at a distance of 60-70cm from the operator eye.
6)The room should be well ventilated and illuminated.
7)The system should have power savind devices.
8)The table should have the leg support to prevent sciatic nerve and popliteal artery compression.
9)In between the work operator should take break,and should do some streches and exercises such as:-
a)close the eyes for few minutes and then open for regulation of circulation in occular muscles.
b)active mobilisation in all the directions of all the joints.
c)take a walk around if possible otherwise simply stand for sometime.
