The effects of neutral posture deviation on perceived joint discomfort ratings in sitting and standing postures
Ergonomics, (1993)
Abstract
There is a pressing need to rank body deviations from
neutral postures which occur due to variety of body
movements around different joints. Such knowledge is
needed to better understand potentially adverse effects
of poor working postures on the industrial population.
The main objective of this study was to examine the
effects of postural deviations on perceived joint
discomfort ratings assessed under similar working
conditions. Twelve males and seven females participated
in the laboratory study. The results revealed several
distinct classes of joint deviations from neutral
postures, which need to be assigned different weights
of postural stress. A preliminary ranking system for
assessment of stressfulness of human body deviations
about different joints was proposed.
