Título Factors related to working posture and its assessment among keyboard operators
Información bibliográfica Feb. 1991, Vol.22, No.1, p.29-35. 34 ref.
Resumen Video analysis of 15 keyboard operators was conducted over two four-hour periods to determine the effects of symptoms of over-use injury, the adjustability of the workstation, the type of keyboard, time of day and sex on working posture. The only factor which significantly affected posture was the type of keyboard, with operators at typewriters adopting a more extended shoulder position, reduced elbow flexion and increased wrist flexion, than those working at a VDU terminal. Analysis of the components of variance associated with repeated observations revealed that to minimise the variance associated with recording the posture of these subjects, and therefore obtain a representative mean posture, required at least nine observations for wrist angle, four for elbow angle, six for shoulder angle and three for trunk incline. The mean posture adopted by this group of operators was similar to the 'right angles' posture, with the trunk reclined 4°, shoulder extended 1°, elbow 92° and wrist extended 7°.
