Background
·
UI prevalence increases 11 times during
pregnancy
·
32-64% of pregnant women have UI
·
PFMT during pregnancy reduces UI at the end of
pregnancy and up to 3 months after delivery
·
Moderate intensity general exercise (walking,
cycling) does not cause fetal effect on blood supply
·
However, PFM and uterus share vascular supply
Study
·
Healthy pregnancies
·
26 women in intervention group, 33 controls
·
Intervention group
o Daily
PFM exercises - 16 weeks
o 6
to 8 second hold, 10 reps, four positions (left side lying, sitting, quadruped,
standing)
o Adherence
diary
o Weekly
PT sessions
·
Ultrasound measure of blood flow (pulse indices)
- unblinded
o Uterine
artery - common iliac artery to uterus
o Umbilical
artery - placenta to baby
o Middle
cerebral artery - fetal brain
Results
·
No significant changes in umbilical artery and
middle cerebral artery from intervention to control or before and after
exercise
·
significant decrease in uterine artery blood
flow at 36 weeks after exercise
Limitations - see paper
Discussion
·
Other studies have shown no changes in umbilical
artery flow even with changes in uterine blood flow
·
Need studies on women with pregnancy
complications
Conclusion - PFM exercises do not affect the fetus and
should be recommended in healthy pregnancies.
