(3)Operation of levers and other mechanical devices;
(4)Maintenance of unbalanced postures while performing these tasks;

Aggravating factors for back injury and spine health issues are:-
(1)Gross overloading of the spine;
(2)Lifting with a bent back or with the object held well out from the body or to one side;
(3)Loss of balance while lifting;
(4)Using a jerking or twisting lifting motion;
(5)Unexpected weight bearing;
(6)Restricted room to maneuver;

Many jobs require performance of tasks in the seated position. Constant sitting in unergonomically designed chairs in stressful postures dictated by visual or manipulative tasks is a common source of recurrent or persistent back pain. Appropriate workplace and chair design promote maintenance of correct posture and the prevention of postural strain and spine health issues.
