Q

Supine compression of IVC by the uterus causes most pronounced effects after what weeks?

A

20 weeks

17
Q

Lymphatic stress in pregnancy caused by fascial torsion, organ hypertrophy, diaphragm restriction have what effect on the pressure gradient?

A

Makes it less effective

18
Q

Most lymphatic sx occur in what trimester?

A

3rd trimester

Increased mass causes increased venous stasis

19
Q

Low back pain in pregnancy can be caused by stagnant hypoxial of neural and vertebral tissues due to what?

A

Direct pressure on IVC by uterus => dependent edema moves back into vasculature due to osmotic gradient

20
Q

Women incapacitated by LBP during pregnancy have higher levels of what hormone?

A

Relaxin

21
Q

Relaxin is elevated in what trimester?

A

1st trimester

Declines early 2nd trimester

22
Q

What does the hormone relaxin cause?

A

Widening and mobility of SI joints and pubic symphysis

Begins in 10-12 weeks

23
Q

What effect does the release of progesterone during pregnancy have on the thoracic cage?

A

Circumference increases 5-7 cm

Subcostal angle widens 68-103 degrees

Diaphragm pushed superiorly 4cm

Increased tidal volume 30-40%

24
Q

Indications for OMT during pregnancy

A

SD

Scoliosis or other pregnancy-associated structural dysfunction

Edema, congestion, or other pregnancy-associated conditions amenable to OMT

25
Q

Relative contraindications to OMT during pregnancy

A

Premature preterm rupture of membranes

Premature labor (change in cervix)

26

Prolapsed umbilical cord

Placental abruption

Ectopic pregnancy

Placenta previa

Threatened/incomplete abortion

Severe preeclampsia/eclampsia

27
Q

Goals of pregnancy OMT

A

Address all postural stressors

Treat any specific SD (allows body to better compensate for pregnancy chage, saves pt energy, MSK dysfunction increases demands up to 300%)

C2

T5-9

29

A

2nd trimester

31
Q

How is diagnosis of pubic symphysis rupture made?

A

Separation >1cm

Audible crack may be heard, acute pain radiating to back and/or thighs, palpable gap with local tissue edema, waddling gait with increased pain on gait or bending

32
Q

How long after delivery should you screen for somatic dysfunction?

A

Day 1 post-partum

Tx prior to resolution of homronal change on ligamentous structures

33
Q

How long post-partum should the second OSE occur?

A

4 weeks postpartum (2nd visit)

34
Q

What are the ACOG recommendations for exercise in pregnancy?

A

30 min or more, moderate exercise, most/all days of the week

35
Q

Should the valsalva maneuver be avoided in pregnancy exercise?

A

Yes, increased BP and intraabdominal pressure may decrease uteroplacental blood flow

36
Q

A

6000 feet

37
Q

Relative contraindications to aerobic exercise in pregnancy

Ruptured membranes

Preeclampsia/pregnancy-induced HTN

Incompetent cervix

Multiple gestation

IUGR

39
Q

The PROMOTE study by Dr. Hensel aimed to use OMT on women in what trimester to reduce LBP?
