ABSTRACT
Frequently, MMH tasks must be performed in unusual postures. These tasks are performed occasionally, but not frequently. Very little data are available to help design MMH tasks that are performed in unusual postures. Furthermore, the available data are based on either the psychophysical design approach or the static strength approach. Here we present design data for lifting, pushing and pulling in unusual postures. The lifting data conform to the psychophysical and biomechanical design criteria. The push and pull data are based on maximum volitional isometric (static) strength.
