It must be pointed out that we made inferences about spatial fit, from body dimensions measured in a rigid
upright posture that does not represent the actual working posture (Kroemer, 1989). Further, the selfselected
height and the onset of effort were assessed after task performance of only a few minutes. The only
other study on spatial design requirements for pregnant women concerns the definition of a foetal region for
seated pregnant women in research on the protection in motor vehicle crashes (Culver and Viano, 1990).
Further study is necessary and may be directed to:
(1) the effects of pregnancy while working at common
workplace layouts using criteria such as comfort,
working posture and performance;
(2) specific requirements of pregnant women regarding
the workplace layout; and
(3) the effects of pregnancy amongst skilled female
workers in normal (non-artificial) work situation.
