Workstation Ergonomics (improper posture)

WORKSTATION ERGONOMICS

Introduction

The capacity to move from a seat to an upright position is kinetically considered as an important indicator for physical independence . The capability is also considered as a marker for risk of falls (Campbell et al , 1989 . In the field of human kinetics , the ability to maintain balance through particular physical examinations is employed to determine the level of agility of a person . There are also tests that allow scoring an individual 's agility and these are mainly based on the time to complete a task of moving

from a sitting to a standing position

Standing up pertains to an action that involves the shift of the body from a stable stance to another position that involves the coordination of almost all parts of the human body . The simultaneous movement from a sitting to a standing position is thus associated with two major issues associated with the musculoskeletal system . The voluntary action of a number of body parts assists in the transformation of an individual 's posture from that of being seated to standing upright . In addition there is a need for a control and maintenance of the body 's equilibrium as the center of gravity is shifted during the transition from sitting to standing . The displacement of the center of gravity generally involves moving in a forward fashion , coupled with a backward and vertical movement of the other parts of the body . This study aims to determine the effect of posture at the workstation on the...
