Evaluation of working postures: review and newest results
conference paper
A working posture is currently being evaluated mainly by regarding various body segments independently. Head/neck posture is mostly evaluated on the basis of experimental, biomechanical modelling and epidemiological studies relating neck load and health complaints to the inclination of the segment defined (head, neck, or head and neck as one). The evaluation of upper arm posture relies on similar types of studies relating shoulder (girdle) load and health complaints to the amount of upper arm elevation. Both measures of musculoskeletal load are to be seen as an equivalent of the force delivered to counteract the gravitational force on the body segment. From the review, however, it also appeared that some additional determinants of musculoskeletal load may be of importance in posture evaluation, i.e. the position of the head and/or neck with respect to the trunk, as well as the position of the upper arm with respect to the trunk.
