A. Genaidy et al., RANKING OF STATIC NONNEUTRAL POSTURES AROUND THE JOINTS OF THE UPPER EXTREMITY AND THE SPINE, Ergonomics, 38(9), 1995, pp. 1851-1858
Constrained body postures are usually cited as the major cause of musc
uloskeletal static loading. Thus, the main goal of the present study w
as to develop a ranking system for the stressfulness of the non-neutra
l static postures around the wrist, elbow, shoulder, neck and lower ba
ck. This was based on the ratings of perceived discomfort. Sixteen men
participated in the study. The results indicated that static postural
stresses yielded varying effects on the discomforting rating levels.
On the basis of these preliminary findings, a ranking system was devel
oped for the stressfulness of non-neutral postures around the joints o
f the upper extremity and the spine.
