Our upright position makes us
unique amongst mammals and, however
this evolutionary development has made
giving birth much more difficult and those
difficulties can be made much more worse
when we do not even take the advantages
of the help that gravity can provide.
History, worldwide prevalence, recent
research, and number of trials, suggest that
upright posture during labor is associated
with shorter duration of labor, reduced
reporting of labor pain, fewer instrumental
deliveries, operative births, fewer abnormal
fetal heart rate patterns and less postpartum
depression
