title: Ranking of static non-neutral postures around the joints of the upper extremity and the spine.
abstract: Constrained body postures are usually cited as the major cause of musculoskeletal static loading. Thus, the main goal of the present study was to develop a ranking system for the stressfulness of the non-neutral static postures around the wrist, elbow, shoulder, neck and lower back. 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 developed for the stressfulness of non-neutral postures around the joints of the upper extremity and the spine.
