Introduction
Antenatal care is the care of the woman during pregnancy. The primary
aim of antenatal care is to achieve at the end of a pregnancy as a healthy
mother and a healthy baby. Ideally this comprise the series of events
occurring from conception through first second & 3rd trimester of the
pregnancy to the delivery of child
Presentation title 3
• First trimester- (0-12 weeks)- in this trimester both mother & fetus are
changing rapidly includes –
• Morning sickness – due to increase in level of hormones to sustain pregnancy
• Mood swings irritability & other physical symptoms – due to surges in
hormones
• Increase frequency of urination
• Reduced peristalsis of alimentary tract
• Second trimester (13-27 weeks)- the symptoms of the 1st trimester may
improve, baby grows larger & women begins to show larger belly
• appetite & weight
• Mother experiencing the movement of fetus (starts- 20 weeks)
• Skin pigmentation on face & belly due to pregnancy hormones
• Reduction in need to urinate often as uterus grows out of pelvic cavity,
reliveing pressure on the bladder 4
• Third trimester-(28-40 weeks)- physical & emotional challeges increases as
the fetus grows more in size & weight. Baby is considered full term at the
end of 37 weeks
• Edema on ankle, hand& face due to retained fluid
• Skin pigmentation becomes more apparent
• Backache
• Fourth trimester (first 12 weeks of postpartum)

PHYSIOLOGICAL CHANGES IN
ANTENATAL CARE
Presentation title 6
CHANGES IN GENITAL ORGAN
VULVA- becomes oedematous & hyperaemic
• Superficial varicosities may appear specially in multiparae
• Labia minora are pigmented & hypertrophied
VAGINA- vaginal walls become hypertrophied oedemantous & more vascular
• Increase blood supply of venous plexus surrounding the walls
• The length of the anterior vaginal walls is increased
• Secretion- copious, thin, & curdy white
• PH- acidic 3.5-6
• UTERUS- non pregnant state weighs about 60gm with the cavity of 5-10ml &
measures about 7.5 cm in length
• At terms it weighs about 900-1000gm & measures 35 cm in length
• Changes occurs in part of uterus body , cervix, isthmus
• There is an increase in growth a& enlargement of uterus
• Changes in muscle-1) hypertrophy & hyperplasia- occurs under the influence of
hormones estrogen & progesterone- limited to first half of pregnancy &
pronounced up to 12 weeks
2)stretching- the muscle fibers further elongate beyond
20 weeks due to distension by the growing fetus the
Wall becomes thinner
At term- measures about 1.5cm or less
8
• ARRANGEMENT OF MUSCLE FIBERS- 1) outer longitudinal- hood like
arrangement over the fundus; some fibres are continuous with round ligament
2) Inner circular- scanty & have sphincter like arrangement around the tubal
orifices
3) Intermediate- thickest & strongest layer arranged in criss-cross fashion through
which the blood vessels run.
9
VASCULAR SYSTEM- uterine artery diameter becomes double
• Blood flow increases by 8 folds at 20 weeks of pregnancy
• Vasodilatation is mainly due to estradiol & progesterone
• Veins become dilated & are valveless , numerous lymphatic channels opens up
the vascular changes are most pronounced at the placental site
WEIGHT- the increase in weight is due to increased growth of uterine muscles,
connective tissue & vascular channels
SHAPE- Nonpregnant pyriform shape is maintained in early months
• Changes to globular at 12 weeks
• As the uterus enlarges, the shape once more becomes pyriform or ovoid by 28
weeks
• changes to spherical beyond 36th week
11
POSITION- Normal anteverted position is exaggerated up to 8 weeks
• the enlarged uterus may lie on the bladder
• Afterwards, it becomes erect, the long axis of the uterus conforms more or less
to the axis of the inlet, there is a tendency of anteversion
• In primigravidae with good tone of abd muscle it is held firmly against the
maternal spine
Contractions (Braxton-Hicks):- The contractions are irregular, infrequent,
spasmodic and painless without any effect on dilatation of the cervix
ISTHMUS- During the first trimester, isthmus hypertrophies and elongates to
about 3 times its original length.
• It becomes softer
12
CERVIX- hypertrophy and hyperplasia of the elastic and connective tissues.
• Vascularity is increased
• softening of the cervix (Goodell’s sign)
• Epithelium: the squamous cells become hyperactive
• Secretion: The secretion is copious and tenacious
• Anatomical: The length of the cervix remains unaltered but becomes bulky. The
cervix is directed posteriorly but after the engagement of the head, directed in
line of vagina.
FALLOPIAN TUBE- The total length is somewhat increased.
• The tube becomes congested.
• Muscles undergo hypertrophy.
• Epithelium becomes flattened, and patches of decidual reaction are observed 13
14
OVARY- The growth and function of the corpus luteum reaches its maximum at 8th
week
• it measures about 2.5 cm and becomes cystic
• Hormones estrogen and progesterone—secreted by the corpus luteum maintain
the environment for the growing ovum before the action is taken over by the
placenta
• These hormones not only control the formation and maintenance of decidua of
pregnancy but also inhibit ripening of the follicles
• Breast- 2-4 weeks unusual tenderness and tingling may be experienced in the
breasts and enlargement begins soon- nodular & lumpy
• There is an increase in blood supply (veins may become visible on the chest)
• There maybe evidence of striation due to stretching of cutis
• 8 weeks-sebaceous glands in the pigmented area around the nipples become
enlarged and more active, appearing as noduless (Montgomery’s tubercles)
• 12 weeks-the nipples and an area around them (the primary and secondary
areolae), become more pigmented and remain so for as much as 12 months
after parturition. a little serous fluid may be expressed from the nipple
• 16 week- colostrum can be expressed.
• Human milk ‘comes in’ about the 3rd or 4th postpartum day.
15
16
• CUTANEOUS CHANGES-
Face(chloasma gravidarum or pregnancy mask)- an extreme form of pigmentation
around the cheeks forehead & around the eyes – patchy or diffuse; disappears
spontaneously after delivery
Breast
Abdomen- linea nigra- brownish black pigmented area
In midline stretching from xiphisternum to symphysis
Pubis
Striae gravidarum- slightly depressed marks with varying length & breadth found
in pregnancy
Vascular spider & palmar erythema
17
HAEMATOLOGICAL CHANGES
BLOOD VOLUME- due to increased in vascularity of enlarging uterus, blood volume
is markedly raised during pregnancy
• The blood volume starts to increase from about 6th week expands rapidly
thereafter to max 40-50% above nonpregnant level at 30-32 weeks
PLASMA VOLUME- starts to in 6 weeks
• Rate of increase almost parallels to blood volume
• Reached to the extent of 50%
• Total plasma volume increase to the extent of 1.25 liter
18
RBC & HAEMOGLOBIN- RBC mass has increased to the extent of 20-30%
• Increase in demand of o2 transport during pregnancy
• Disproportionate increase in plasma & RBC volume produces state of
hemodilution(fall in hematocrit)
• Hb fall is about 2gm% from the non pregnant value
19
METABOLIC CHANGES
GENERAL METABOLIC CHANGES- total metabolic is increased due to the needs of
growing fetus & the uterus
• Basal metabolic rate is increased to the extent of 30% higher than that of avrg
non pregnant women
PROTIEN METABOLISM- positive nitrogenous balance throughout pregnancy
• At term, the fetus & placenta contains about 500gm of protein & maternal gain is
also about 500gm
CARBOHYDRATE METABOLISM- insulin secretion is in response to glucose &
Amino acid
• Hyperplasia & hypertrophy of beta cells of pancreas
• Increase insulin level favors lipogenesis (fat storage) this mechanism ensures
continuous supply of glucose to the fetus
20
• FAT METABOLISM- an avrg of 3-4 kg of fat is stored during pregnancy mostly in
the abdominal wall, breast, hips & thighs
• IRON METABOLISM- : Iron is absorbed in ferrous form from duodenum and
jejunum and is released into the circulation as transferrin
• About 10% of ingested iron is absorbed
• Total iron requirement during pregnancy is estimated approximately 1,000 mg
• In the absence of iron supplementation, there is drop in hemoglobin, serum
iron and serum ferritin concentration at term pregnancy Thus, pregnancy is an
inevitable iron deficiency state
21
WEIGHT GAIN
• In early weeks, the patient may lose weight because of nausea or vomiting.
During subsequent months, the weight gain is progressive until the last 1 or 2
weeks, when the weight remains static.
• The total weight gain during the course of a singleton pregnancy for a healthy
woman averages 11 kg
• This has been distributed to 1 kg in first trimester and 5 kg each in second and
third trimester.
• Importance of weight checking: Rapid gain in weight of more than 0.5 kg a week
or more than 2 kg a month ,in later months of pregnancy may be the early
manifestation of preeclampsia and need for careful supervision.
• Stationary or falling weight may suggest intrauterine growth retardation or
intrauterine death of fetus.
• Obese women are in increased risk of complications in pregnancy, labor and
puerperium
22
The total weight gain at term is
distributed approximately as:-

RY
ENDOCRINE SYSTEM
• The changes of pregnancy are orchestrated by hormones progesterone,
estrogens and relaxin seem to be the most important for the physiotherapist.
Increased joint laxity has been demonstrated in pregnancy
•
25
MUSCULOSKELETAL CHANGES
• Increase in joint laxity and joint ranges
• There is increased mobility of the pelvic joints due to softening of the ligaments
caused mainly by hormone
• Increase in water retention- oedema & nerve compression
• The distance between the two rectus abdominis muscles can be seen to widen
throughout a pregnancy and the linea alba may even split under the strain
(diastasis recti), and this may lead to poorer
mechanical function. (elongation of muscle)
• the lumbar and thoracic curves are increased
during later months of pregnancy due to enlarged uterus produces backache and
waddling gait.
26
RESPIRATORY SYSTEM
• With the enlargement of the uterus there is elevation of diaphragm 4cm &
breathing becomes diaphragmatic
• Subcostal angle (68-103)*
• Transverse diameter of chest expands -2cm ;chest circumference 5-7cm
• The mucosa of the nasopharynx becomes hyperemic and edematous. This may
cause nasal stuffiness and rarely epistaxis.
• A state of hyperventilation occurs
during pregnancy leading to increase
in tidal volume and therefore
respiratory volume by 40%
• Due to progesterone acting on repi
Centre
• in sensitivity centre of co2 the
Women feels shortness of breath 27
NERVOUS SYSTEM
• Some sorts of temperamental changes are found during pregnancy and in the
puerperium. Nausea, vomiting, mental irritability and sleep disorders are
probably due to some psychological background
• Postpartum blues, depression or psychosis may develop in a susceptible
individual
• Water retention quite frequently causes unusual pressure on nerves, particularly
those passing through canals formed of inelastic material like bone and fibrous
tissue (e.g. the carpal tunnel), with resulting neuropraxia. This can be relieved by
the use of lightweight splint
• There is an increase in threshold to pain at full term and in labor probably due to
increased levels of plasma endorphins and progesterone
• CSF pressure remains unchanged during pregnancy but is increased during
uterine contractions and bearing down. There is more dependence on
sympathetic nervous system for maintenance of hemodynamics. 28
CARDIOVASCULAR SYSTEM
29
• ANATOMICAL CHANGES: Due to elevation of the diaphragm consequent to the
enlarged uterus, the heart is pushed upward and outward with slight rotation
to left
• Muscle particularly, the left ventricles hypertrophies leading to enlargement of
the heart
• During pregnancy the heart rate & stroke vol(amount of blood pumped by a
heart with each beat) due to the increase blood volume & o2 requirement of
maternal tissue and growing foetus
Cardiac output
• The cardiac output (CO) starts to increase from 5th week of pregnancy and
reaches its peak 40–50% at about 30–34 weeks
• CO is lowest in the sitting or supine position and highest in the right or left lateral
or knee chest position
• Cardiac output increases further during labor (+50%) and immediately following
delivery (+70%)
BLOOD PRESSURE- during mid-trimester, changes in blood pressure may occur
causing fainting
• In later pregnancy hypotension may occur in 10% of women in unsupported
supine position termed as SUPINE HYPOTENSION SYNDROME (POSTURAL
HYPOTENSION)
• The pressure of gravid uterus compresses the vena cava, reduces the venous
return due to which the cardiac output is by 25-30% & blood pressure may fall
by 10-15%
Presentation title 30
REGIONAL DISTRIBUTION OF BLOOD FLOW
• Uterine blood flow - increased from 50 mL/min in nonpregnant state to about
750 mL near term.
• Pulmonary blood flow (normal 6,000 mL/min) is increased by 2,500 mL/min
• Renal blood flow (normal 800 mL) increases by 400 mL/min at 16th week and
remains at this level till term
• The blood flow through the skin and mucous membranes reaches a maximum of
500 mL/min by 36th week.
• Heat sensation, sweating or stuffy nose complained by the pregnant women can
be explained by the increased blood flow
Presentation title 31
URINARY SYSTEM / RENAL
• Kidney- enlarge in length 1cm
• Renal plasma flow 50-75% max
• Glomerular filtration rate (GFR) 50% throughout pregnancy
• Ureter –become atonic due to high progesterone & so that they are a little
dilated
• Hypertrophy of muscle & sheath of ureter specially pelvic due to estrogen
• There is an increased urinary output, and small changes in tubular resorption
• Bladder- hypertrophy of muscle & elastic tissue of the wall
• Late pregnancy- bladder mucosa becomes edematous & stress incontinence
due to urethral sphincter weakness, frequency of micturition reappears
• 6-8 weeks- frequency of micturition (subsides 12 weeks)
32
b
ALIMENTARY SYSTEM
33
• Nausea ,vomiting -if inappropriately managed in severe cases (hyperemesis
gravidarum) can lead to maternal dehydration, malnutrition and weight loss
• The gut musculature becomes slightly hypotonic and the motility of GIT is
decreased due to high progesterone level
• Increased salivation (ptyalism)
• Taste is often altered very early in pregnancy Increased appetite & thirst –
frequent small snacks
• Heart burn- (reflux esophagitis) relaxation of cardiac sphincter due to
progesterone & relaxin
• Emesis gravidarum- morning sickness 50%
• Constipation- reduced gut motility due to progesterone
Increased water & salt absorption
LIVER AND GALLBLADDER
• Although there is no histological change in the liver cells, but the functions are
depressed. With the exception of raised alkaline phosphatase levels, other liver
function tests are unchanged
• There is mild cholestasis (estrogen effect).
• There is marked atonicity of the gallbladder (progesterone effect)
This, together with high blood cholesterol level during pregnancy, favors stone
formation
34
Physiotherapy management in
antenatal care
Presentation title 35
Aims
• to promote and maintain optimal physical and emotional maternal health
throughout pregnancy
• to recognize and treat correctly medical or obstetric complications occurring
during pregnancy
• to detect fetal abnormalities as early as possible
• to prepare for and inform both parents about pregnancy, labor, the
puerperium and the subsequent care of their baby
• the overriding goal is that pregnancy will result in a healthy mother
and a healthy infant
Presentation title 36
• Offering education for parenthood
• To prepare women for labor, lactation & care for infants
• To develop awareness and control of posture during and after pregnancy
• To prepare for labor, delivery and post partum activities
• To teach the mother elements of child care, nutrition, personal hygiene, and
environmental sanitation
Presentation title 37
ROLE OF PHYSIOTHERAPY IN
ANTENATAL CARE
 Prevention/treatment of musculoskeletal problems
 Promoting healthy lifestyle
 Postural & ergonomic advice
 Preparing for labor
 Teaching relaxation technique
 Optimal physical fitness
Presentation title 38
Biomechanics on child bearing year
• During pregnancy a number of biomechanical & hormonal changes occur that can
alter spinal curvature, balance & gait patterns
• The significant physical & physiological changes occur during child bearing year
require musculoskeletal adaptations
• Lumbopelvic instability
• Postural deviations
• Modified lower extremity weight bearing & challenges with balance & gait
39
Presentation title 40
• FUNCTIONS OF LOCAL MUSCLE SYSTEM- local muscle play an imp role in
stabilizing joints of pelvic girdle & vertebral column
• Transverse abdominis with multifidus including their fascia creates a corset of
support for the lumbopelvic region
• According to Richardson & coworkers co-contractions of transverse abdominis &
multifidus increases the stiffness of SI joint
• POSTURAL DEVIATIONS-
41

42
• MODIFIED LOWER EXTREMITY WEIGHT BEARING- static & dynamic changes of
lower limb
• Increased weight & anterior displacement of COG compensated by biomechanical
changes that results in posterior displacement of trunk center of mass
• The biomechanical changes related to realignment of spinal curvature include
increase in sagittal pelvic tilt
• CHALLENGES WITH BALANCE- balance & control of movement starts affected
mainly during 3rd trimester
• Static postural control decreases in situation of reduced base of support
• Decrease in postural stability of pregnant women increases the risk of fall when
compared to normal women

Goals & treatment during antenatal
period
• To educate the mother regarding changes of pregnancy
• To increase & maintain CVS fitness
• To maintain abdominal function & prevent to diastasis recti or correct if it exist
• To train the mother for improving control strength of pelvic floor muscle by
educating awareness regarding it
• To prevent msk injury by teaching specific exercises & preventive measures
• To encourage resistance training to muscle strength & endurance
• To educate correct body mechanics & diff positions
• To improve the postural deviation & maintain it by increasing the awareness of
posture control
• To prepare the mother for labor & postnatal exercise & it imps
46
Prevention/treatment of musculoskeletal problems
posture
• Pregnancy back care- Postural, hormonal and weight changes, ergonomic
education involving sitting and working positions, bending, lifting and
householdactivities should all be considered
• Nerve compression syndrome- carpal tunnel syndrome
the following may all give relief: • ice packs (a small bag of frozen peas wrapped in a
wet handkerchief could be used at home) • resting with the hands in elevation •
wrist and hand exercises • ultrasound • splinting limiting wrist flexion
47
SI joint
• Pregnancy could have many possible effects on the sacroiliac joint; for example
joint laxity may allow repetitive new movement at one, or both, joints causing
pain, if combined with sufficient activity
• This usually disappears in a few months, but indicates transient stress. A
support belt may provide comfort for some women
• various self help maneuver can be taught to relive SPD
48
• SCIATICA- h reduced activity levels, within pain-free range.
Advice from the physiotherapist on positioning, back care, posture correction,
activities of daily living and pain relief
• COCCYDYNIA- this condition is rare antenatally unless caused by a fall.
cushion when sitting, taking pressure through ischial tuberosities and thighs • ice
packs, heat, and TENS.
49
SYMPHYSIS PUBIS DYSFUNCTION (SPD)
• Difficult activities will include: • getting in or out of the car or bath • changing
position in bed, particularly ‘turning over’ • dressing • walking, which is
severely restricted or impossible. The possible link with sacroiliac dysfunction
• Rest and reduction of non-essential ‘chores’
• keeping the legs adducted and avoiding single leg standing
• Pelvic support may reduce pain levels
• Gentle isometric contraction of hip adductors, in sitting – small cushion
between the knees (whilst maintaining pelvic stability), may relieve adductor
tension.
50
• MUSCLE CRAMP- • calf stretches to relieve muscle spasm
• knee extension with dorsiflexion will release calf cramp
• massage – deep kneading
• vigorous foot exercises, to prevent the bruise-like pain which often follows a
cramp ‘event’
• a pre-bedtime brisk walk, vigorous foot exercises, and a warm bath may be
prophylactic
Ankle dorsiflexion and plantar flexion, and foot circling carried out for 30 seconds
regularly, should be suggested; women should be advised not to cross the knees
when sitting
51
General Guidelines for Exercise

a. mental imagery.
b. muscle setting – “Jacobson’s Method”
Presentation title 68
Touch relaxation
• It is used by involving the partner as the touch of partner seems to
provide relaxation
• Touch relaxation is responding to womens labour partners touch by
relaxing or releasing tense muscle
• This can be done with gentle pressure or stroking
• Women can start by tensing and releasing to her labour partners touch

PRENATAL PHYSIOTHERAPY / antenatal pt management

  • 2. Agenda Introduction Maternal physiology Antenatal care -aims -role of physiotherapy -references Presentation title 2
  • 3. Introduction Antenatal care is the care of the woman during pregnancy. The primary aim of antenatal care is to achieve at the end of a pregnancy as a healthy mother and a healthy baby. Ideally this comprise the series of events occurring from conception through first second & 3rd trimester of the pregnancy to the delivery of child Presentation title 3
  • 4. • First trimester- (0-12 weeks)- in this trimester both mother & fetus are changing rapidly includes – • Morning sickness – due to increase in level of hormones to sustain pregnancy • Mood swings irritability & other physical symptoms – due to surges in hormones • Increase frequency of urination • Reduced peristalsis of alimentary tract • Second trimester (13-27 weeks)- the symptoms of the 1st trimester may improve, baby grows larger & women begins to show larger belly • appetite & weight • Mother experiencing the movement of fetus (starts- 20 weeks) • Skin pigmentation on face & belly due to pregnancy hormones • Reduction in need to urinate often as uterus grows out of pelvic cavity, reliveing pressure on the bladder 4
  • 5. • Third trimester-(28-40 weeks)- physical & emotional challeges increases as the fetus grows more in size & weight. Baby is considered full term at the end of 37 weeks • Edema on ankle, hand& face due to retained fluid • Skin pigmentation becomes more apparent • Backache • Fourth trimester (first 12 weeks of postpartum) Presentation title 5
  • 6. PHYSIOLOGICAL CHANGES IN ANTENATAL CARE Presentation title 6
  • 7. CHANGES IN GENITAL ORGAN VULVA- becomes oedematous & hyperaemic • Superficial varicosities may appear specially in multiparae • Labia minora are pigmented & hypertrophied VAGINA- vaginal walls become hypertrophied oedemantous & more vascular • Increase blood supply of venous plexus surrounding the walls • The length of the anterior vaginal walls is increased • Secretion- copious, thin, & curdy white • PH- acidic 3.5-6
  • 8. • UTERUS- non pregnant state weighs about 60gm with the cavity of 5-10ml & measures about 7.5 cm in length • At terms it weighs about 900-1000gm & measures 35 cm in length • Changes occurs in part of uterus body , cervix, isthmus • There is an increase in growth a& enlargement of uterus • Changes in muscle-1) hypertrophy & hyperplasia- occurs under the influence of hormones estrogen & progesterone- limited to first half of pregnancy & pronounced up to 12 weeks 2)stretching- the muscle fibers further elongate beyond 20 weeks due to distension by the growing fetus the Wall becomes thinner At term- measures about 1.5cm or less 8
  • 9. • ARRANGEMENT OF MUSCLE FIBERS- 1) outer longitudinal- hood like arrangement over the fundus; some fibres are continuous with round ligament 2) Inner circular- scanty & have sphincter like arrangement around the tubal orifices 3) Intermediate- thickest & strongest layer arranged in criss-cross fashion through which the blood vessels run. 9
  • 10. VASCULAR SYSTEM- uterine artery diameter becomes double • Blood flow increases by 8 folds at 20 weeks of pregnancy • Vasodilatation is mainly due to estradiol & progesterone • Veins become dilated & are valveless , numerous lymphatic channels opens up the vascular changes are most pronounced at the placental site WEIGHT- the increase in weight is due to increased growth of uterine muscles, connective tissue & vascular channels SHAPE- Nonpregnant pyriform shape is maintained in early months • Changes to globular at 12 weeks • As the uterus enlarges, the shape once more becomes pyriform or ovoid by 28 weeks • changes to spherical beyond 36th week
  • 11. 11
  • 12. POSITION- Normal anteverted position is exaggerated up to 8 weeks • the enlarged uterus may lie on the bladder • Afterwards, it becomes erect, the long axis of the uterus conforms more or less to the axis of the inlet, there is a tendency of anteversion • In primigravidae with good tone of abd muscle it is held firmly against the maternal spine Contractions (Braxton-Hicks):- The contractions are irregular, infrequent, spasmodic and painless without any effect on dilatation of the cervix ISTHMUS- During the first trimester, isthmus hypertrophies and elongates to about 3 times its original length. • It becomes softer 12
  • 13. CERVIX- hypertrophy and hyperplasia of the elastic and connective tissues. • Vascularity is increased • softening of the cervix (Goodell’s sign) • Epithelium: the squamous cells become hyperactive • Secretion: The secretion is copious and tenacious • Anatomical: The length of the cervix remains unaltered but becomes bulky. The cervix is directed posteriorly but after the engagement of the head, directed in line of vagina. FALLOPIAN TUBE- The total length is somewhat increased. • The tube becomes congested. • Muscles undergo hypertrophy. • Epithelium becomes flattened, and patches of decidual reaction are observed 13
  • 14. 14 OVARY- The growth and function of the corpus luteum reaches its maximum at 8th week • it measures about 2.5 cm and becomes cystic • Hormones estrogen and progesterone—secreted by the corpus luteum maintain the environment for the growing ovum before the action is taken over by the placenta • These hormones not only control the formation and maintenance of decidua of pregnancy but also inhibit ripening of the follicles
  • 15. • Breast- 2-4 weeks unusual tenderness and tingling may be experienced in the breasts and enlargement begins soon- nodular & lumpy • There is an increase in blood supply (veins may become visible on the chest) • There maybe evidence of striation due to stretching of cutis • 8 weeks-sebaceous glands in the pigmented area around the nipples become enlarged and more active, appearing as noduless (Montgomery’s tubercles) • 12 weeks-the nipples and an area around them (the primary and secondary areolae), become more pigmented and remain so for as much as 12 months after parturition. a little serous fluid may be expressed from the nipple • 16 week- colostrum can be expressed. • Human milk ‘comes in’ about the 3rd or 4th postpartum day. 15
  • 16. 16
  • 17. • CUTANEOUS CHANGES- Face(chloasma gravidarum or pregnancy mask)- an extreme form of pigmentation around the cheeks forehead & around the eyes – patchy or diffuse; disappears spontaneously after delivery Breast Abdomen- linea nigra- brownish black pigmented area In midline stretching from xiphisternum to symphysis Pubis Striae gravidarum- slightly depressed marks with varying length & breadth found in pregnancy Vascular spider & palmar erythema 17
  • 18. HAEMATOLOGICAL CHANGES BLOOD VOLUME- due to increased in vascularity of enlarging uterus, blood volume is markedly raised during pregnancy • The blood volume starts to increase from about 6th week expands rapidly thereafter to max 40-50% above nonpregnant level at 30-32 weeks PLASMA VOLUME- starts to in 6 weeks • Rate of increase almost parallels to blood volume • Reached to the extent of 50% • Total plasma volume increase to the extent of 1.25 liter 18
  • 19. RBC & HAEMOGLOBIN- RBC mass has increased to the extent of 20-30% • Increase in demand of o2 transport during pregnancy • Disproportionate increase in plasma & RBC volume produces state of hemodilution(fall in hematocrit) • Hb fall is about 2gm% from the non pregnant value 19
  • 20. METABOLIC CHANGES GENERAL METABOLIC CHANGES- total metabolic is increased due to the needs of growing fetus & the uterus • Basal metabolic rate is increased to the extent of 30% higher than that of avrg non pregnant women PROTIEN METABOLISM- positive nitrogenous balance throughout pregnancy • At term, the fetus & placenta contains about 500gm of protein & maternal gain is also about 500gm CARBOHYDRATE METABOLISM- insulin secretion is in response to glucose & Amino acid • Hyperplasia & hypertrophy of beta cells of pancreas • Increase insulin level favors lipogenesis (fat storage) this mechanism ensures continuous supply of glucose to the fetus 20
  • 21. • FAT METABOLISM- an avrg of 3-4 kg of fat is stored during pregnancy mostly in the abdominal wall, breast, hips & thighs • IRON METABOLISM- : Iron is absorbed in ferrous form from duodenum and jejunum and is released into the circulation as transferrin • About 10% of ingested iron is absorbed • Total iron requirement during pregnancy is estimated approximately 1,000 mg • In the absence of iron supplementation, there is drop in hemoglobin, serum iron and serum ferritin concentration at term pregnancy Thus, pregnancy is an inevitable iron deficiency state 21
  • 22. WEIGHT GAIN • In early weeks, the patient may lose weight because of nausea or vomiting. During subsequent months, the weight gain is progressive until the last 1 or 2 weeks, when the weight remains static. • The total weight gain during the course of a singleton pregnancy for a healthy woman averages 11 kg • This has been distributed to 1 kg in first trimester and 5 kg each in second and third trimester. • Importance of weight checking: Rapid gain in weight of more than 0.5 kg a week or more than 2 kg a month ,in later months of pregnancy may be the early manifestation of preeclampsia and need for careful supervision. • Stationary or falling weight may suggest intrauterine growth retardation or intrauterine death of fetus. • Obese women are in increased risk of complications in pregnancy, labor and puerperium 22
  • 23. The total weight gain at term is distributed approximately as:- Presentation title 23
  • 24. MATERNAL PHYSIOLOGY ENDOCRINE CARDIOVASCULAR REPRODUCTIVE RENAL & GIT MUSCULOSKELETAL & POSTURAL NEUROLOGICAL 24 RESPIRATO RY
  • 25. ENDOCRINE SYSTEM • The changes of pregnancy are orchestrated by hormones progesterone, estrogens and relaxin seem to be the most important for the physiotherapist. Increased joint laxity has been demonstrated in pregnancy • 25
  • 26. MUSCULOSKELETAL CHANGES • Increase in joint laxity and joint ranges • There is increased mobility of the pelvic joints due to softening of the ligaments caused mainly by hormone • Increase in water retention- oedema & nerve compression • The distance between the two rectus abdominis muscles can be seen to widen throughout a pregnancy and the linea alba may even split under the strain (diastasis recti), and this may lead to poorer mechanical function. (elongation of muscle) • the lumbar and thoracic curves are increased during later months of pregnancy due to enlarged uterus produces backache and waddling gait. 26
  • 27. RESPIRATORY SYSTEM • With the enlargement of the uterus there is elevation of diaphragm 4cm & breathing becomes diaphragmatic • Subcostal angle (68-103)* • Transverse diameter of chest expands -2cm ;chest circumference 5-7cm • The mucosa of the nasopharynx becomes hyperemic and edematous. This may cause nasal stuffiness and rarely epistaxis. • A state of hyperventilation occurs during pregnancy leading to increase in tidal volume and therefore respiratory volume by 40% • Due to progesterone acting on repi Centre • in sensitivity centre of co2 the Women feels shortness of breath 27
  • 28. NERVOUS SYSTEM • Some sorts of temperamental changes are found during pregnancy and in the puerperium. Nausea, vomiting, mental irritability and sleep disorders are probably due to some psychological background • Postpartum blues, depression or psychosis may develop in a susceptible individual • Water retention quite frequently causes unusual pressure on nerves, particularly those passing through canals formed of inelastic material like bone and fibrous tissue (e.g. the carpal tunnel), with resulting neuropraxia. This can be relieved by the use of lightweight splint • There is an increase in threshold to pain at full term and in labor probably due to increased levels of plasma endorphins and progesterone • CSF pressure remains unchanged during pregnancy but is increased during uterine contractions and bearing down. There is more dependence on sympathetic nervous system for maintenance of hemodynamics. 28
  • 29. CARDIOVASCULAR SYSTEM 29 • ANATOMICAL CHANGES: Due to elevation of the diaphragm consequent to the enlarged uterus, the heart is pushed upward and outward with slight rotation to left • Muscle particularly, the left ventricles hypertrophies leading to enlargement of the heart • During pregnancy the heart rate & stroke vol(amount of blood pumped by a heart with each beat) due to the increase blood volume & o2 requirement of maternal tissue and growing foetus
  • 30. Cardiac output • The cardiac output (CO) starts to increase from 5th week of pregnancy and reaches its peak 40–50% at about 30–34 weeks • CO is lowest in the sitting or supine position and highest in the right or left lateral or knee chest position • Cardiac output increases further during labor (+50%) and immediately following delivery (+70%) BLOOD PRESSURE- during mid-trimester, changes in blood pressure may occur causing fainting • In later pregnancy hypotension may occur in 10% of women in unsupported supine position termed as SUPINE HYPOTENSION SYNDROME (POSTURAL HYPOTENSION) • The pressure of gravid uterus compresses the vena cava, reduces the venous return due to which the cardiac output is by 25-30% & blood pressure may fall by 10-15% Presentation title 30
  • 31. REGIONAL DISTRIBUTION OF BLOOD FLOW • Uterine blood flow - increased from 50 mL/min in nonpregnant state to about 750 mL near term. • Pulmonary blood flow (normal 6,000 mL/min) is increased by 2,500 mL/min • Renal blood flow (normal 800 mL) increases by 400 mL/min at 16th week and remains at this level till term • The blood flow through the skin and mucous membranes reaches a maximum of 500 mL/min by 36th week. • Heat sensation, sweating or stuffy nose complained by the pregnant women can be explained by the increased blood flow Presentation title 31
  • 32. URINARY SYSTEM / RENAL • Kidney- enlarge in length 1cm • Renal plasma flow 50-75% max • Glomerular filtration rate (GFR) 50% throughout pregnancy • Ureter –become atonic due to high progesterone & so that they are a little dilated • Hypertrophy of muscle & sheath of ureter specially pelvic due to estrogen • There is an increased urinary output, and small changes in tubular resorption • Bladder- hypertrophy of muscle & elastic tissue of the wall • Late pregnancy- bladder mucosa becomes edematous & stress incontinence due to urethral sphincter weakness, frequency of micturition reappears • 6-8 weeks- frequency of micturition (subsides 12 weeks) 32 b

Editor's Notes

  1. 2nd-Due to high level of progesterone leading to heartburns, indigestion,gas & constipation
  2. muscle-1-not only individual muscle increases in length & breadth but there is limited addition of new mucle fibres Stret- 1.5 or less the uterus feels soft & elastic in contrast to firm feel of nongravid uterus
  3. vascu- uterine enlargement is inconsistent during 2nd half of the pregnancy when stretching factor starts to operate
  4. Uterine contraction in pregnancy has been named after BraxtonHicks who first described its entity during pregnancy. From the very early weeks of pregnancy, the uterus undergoes spontaneous contraction. This can be felt during bimanual palpation in early weeks or during abdominal palpation when the uterus feels firmer at one moment and softer at another. Although spontaneous, the contractions may be excited by rubbing the uterus
  5. n. There are marked hypertrophy and hyperplasia of the glands which occupy about half the bulk of the cervix. All these lead to marked softening of the cervix (Goodell’s sign) which is evident as early as 6 weeks. It begins at the margin of the external os and then spreads upward. It not only provides diagnostic aid in pregnancy but also the changes in the cervix facilitate its dilatation during labor the squamous cells also become hyperactive and the mucosal changes simulate basal cell hyperplasia or cervical intraepithelial neoplasia (CIN). These changes are hormone induced (estrogen) and regress spontaneously after delivery.
  6. . It looks bright orange, later on becomes yellow and, finally pale. Regression occurs following decline in the secretion of human chorionic gonadotropin (hCG) from the placenta. Colloid degeneration occurs at 12th week which later becomes calcified at term . Hormones estrogen and progesterone—secreted by the corpus luteum maintain the environment for the growing ovum before the action is taken over by the placenta These hormones not only control the formation and maintenance of decidua of pregnancy but also inhibit ripening of the follicles. Thus both the ovarian and uterine cycles of the normal menstruation remain suspended. Luteoma of pregnancy results from exaggerated luteinization reaction of the ovary. Decidual reaction: There may be patchy sheet of decidual cells on the outer surface of the ovary. These are metaplastic changes due to high hormonal stimulation. The same stimulus may also produce luteinization of atretic or partially developed follicles.
  7. 1-The rise in oestrogens is responsible for the growth of the duct system and progesterone for that of the alveoli 5-This pigmentation is thought to be due to the stimulation of melanin production by the anterior pituitary
  8. 1-due to interposition of utero placental circulation . The activities of all systems are increased the rise is progressive & inconsistent THE LEVEL REMAINS STATIC ALMOST TILL TERM Plasma-3-the increase is greater in multigravida, in multiple pregnancy & with large baby
  9. Protein- chiefly distributed in uterus,breast & maternal blood Carb-2-sensitivity of insulin receptors is decreased specially during later months of pregnancy 3-There are oestrogen, progesterone cortisol prolactin free fatty acids & increase tissue resistance to insulin this mechanism ensures continuous supply of glucose to the fetus
  10. Fat1 – plasma lipids & lipoproteins increase appreciably during later half of pregnancy due to increased in oestrogen, progesterone -Iron is transported actively across the placenta to the fetus. 3-Iron requirement during pregnancy is considerable and is mostly limited to the second half of the pregnancy especially to the last 12 weeks 3-This is distributed in fetus and placenta 300 mg and expanded red cell mass 400 mg. (Total increase in red cell volume—350 mL and 1 mL contains 1.1 mg of iron.) There is obligatory loss of about 200 mg through normal routes. The iron in the fetus and placenta is permanently lost and a variable amount of iron in the expanded RBC volume is also lost due to blood loss during delivery (45 mg/100 mL) and the rest is returned to the store. However, there is saving of about 300 mg of iron due to amenorrhea for 10 months. (Iron loss in menstrual bleeding per cycle is 30 mg.) Iron need during lactation is 1 mg/day
  11. During pregnancy, there is variable amount of retention of electrolytes—sodium (1,000 mEq), potassium (10 g) and chlorides. The sodium is osmotically active and partially controls the distribution of water in various compartments of the body. Causes of increased sodium retention during pregnancy are: (1) increased estrogen and progesterone, (2) increased aldosterone consequent on the activation of the renin-angiotensin system and possibly (3) due to increased antidiuretic hormone. The amount of water retained during pregnancy at term is estimated to be 6.5 liters. The increased accumulation of fluid in the tissue spaces mainly below the uterus is due to— (1) diminished colloid osmotic tension due to hemodilution driving the fluid out of the vessels and (2) increased venous pressure of the inferior extremities. Thus, slight edema of the legs is not uncommon, in otherwise normal pregnancy
  12. Estrogen-There is evidence to show that the maternal and foetal adrenal glands and the foetal liver also contribute towards oestrogen synthesis in pregnancy . Relaxin - Research suggests that it is produced as early as 2 weeks of gestation, is at its highest levels in the first trimester and then drops by 20% to remain steady
  13. 1-The increased body weight must result in more pressure through the spine, and increased torsional strains on joints. Women become clumsier and are inclined to trip and fall. These factors, together with joint laxity and fatigue 2-In the third trimester there is increased water retention, which may result in a varying degree of oedema of ankles and feet in most women, reducing joint range. The oedema can also cause pressure on nerves, as in carpal tunnel syndrome where oedema in the arms and hands causes paraesthesia and muscle weakness affecting terminal portions of the median and ulnar nerve distributions
  14. Total lung capacity is reduced by 5% due to this elevation. However, diaphragmatic excursion is increased by 1–2 cm and breathing becomes diaphragmatic. Total pulmonary resistance is reduced due to progesterone effect There is a progressive increase in o2 consumption which is caused by the increased metabolic needs between mother & fetus Progesterone is a respiratory stimulant and sensitises chemoreceptors to carbon dioxide (CO2).[13] There is an increased production of CO2 (about 300 ml/min) and due to increased MV, PaCO2 falls to 30–32 mmHg in first trimester and remains in this range throughout pregnancy.  - a state of hyperventilaton occurs during pregnancy leads to increase in tidal vol Maternal o2 consumption is increased by 20-40% due to increased demand of fetus placenta & maternal tissues
  15. The increase in CO is caused by: (1) Increased blood volume. (2) To meet the additional O2 required due to increased metabolic activity during pregnancy. CO is the product of SV and HR (CO = SV × HR). The increase in CO is chiefly affected by increase in stroke volume and increase in pulse rate to about 15 per minute. A normal heart got enough reserve power to cope with the increased load but a damaged heart fails to do so. third trimester the weight of the foetus may compress the aorta and inferior vena cava against the lumbar spine when the woman is lying supine, causing dizziness and even unconsciousness; this is called the ‘pregnancy hypotensive syndrome’.
  16. 2-max by 16 week maintaioned until 34 weeks 3-increase gfr causes reduction in maternal plasma levels of creatinine, blood urea nitrogen,& uric acid renal tubules fails toi reabsorb glucose,uric acid aminoacid water soluble vitamins $ other substances completely U-The musculature of the ureters is slightly hypotonic so that they are a little dilated, and also seem to elongate to circumvent the enlarging uterus; the possible result of these factors may be vesicoureteral reflux or kinking with possible pooling and stagnation of urine; this may predispose to urinary tract infections. 5-there is elongation kinking and outward displacement of ureter B-As the pregnancy progresses the bladder changes position to become an intra-abdominal organ, is pressed upon and even displaced by the increasingly large and heavy uterus. Thus the urethrovesical angle may be altered and the intra-abdominal pressure raised; the smooth muscle of the urethra may become slightly hypotonic, and it seems possible that supportive fascia and ligaments of the tract and pelvic floor may become more lax and elastic 8-oedemantous due to venous & lymphatic obstruction especially in primigravida stage following early engagement ,micturition reappear- due to pressure on bladder as thre presenting part descends down the pelvis 9-may be due to resetting of osmo regulation caused incresse in water intake & polyuria in la 6-caused by the pregnancy may result in excretion of significant amounts of sugar and protein. Diabetes may be first diagnosed in pregnancy because pregnancy is one of the factors that may precipitate its onset in women genetically predisposed to the condition. This usually regresses after delivery (gestational diabetes).
  17. Nausea and vomiting, thought now to be the response of some to HCG, is not necessarily restricted to the early morning, nor does it always cease by the 16th week. It can be aggravated by certain foods, even by their odours, and by iron tablets, (hyperemesis gravidarum) The reduced speed of oesophageal peristalsis, a hormonally mediated slackness of the cardiac sphincter, displacement of the stomach and an increased intra-abdominal pressure as pregnancy progresses, all favour the gastric reflux or ‘heartburn’ of which so many women complain. Cardiac sphincter is relaxed and regurgitation of acid gastric content into the esophagus may produce chemical esophagitis and heart burn. Dyspepsia is common. There is diminished gastric secretion and delayed emptying time of the stomach. Risk of peptic ulcer disease is reduced There is diminished gastric secretion and delayed emptying time of the stomach. Risk of peptic ulcer disease is reduced. Atonicity of the gut leads to constipation, while diminished peristalsis facilitates more absorption of food materials
  18. 1- lumbopelvis instability – 16-32 weeks lumbar curvature increases perception of LBP suggest the adjustment of loading pattern of lumbar spine results in changing shape plays a major role in lumbopelvic instability lumbopelvic-hip region is primarily responsible for transferring the loads generated by body weight & gravity during functional activities such as sitting and standing Apart from that some changes caused by normal actions of hormones such as progesterone , estrogen & relaxin- relaxin main inductor of ligament relaxation leads to increased mobility of pelvic complex & peripheral joints which usually reults in instability of lower & upper segments that predispose individual to lower limb dysfunction
  19. 1- this majorly consist of transverse abdominis, deep fibres of multifidus pelvic floor muscles & diaphrgm optimal functioning of the muscle creates a cylindrical inside the bod y holding the organs & spine in place also knwn as abdominal hollowing
  20. As fetus grows with trimester mothers centre of mass changes which leads to changes in weight distribution pattern of mother thus continuous postural changes are counterbalanced Lumbothoracic curvature along with pelvic tilting are prominently observed Overstretching & weakness of abdominal muscle will result in increase lumbosacral angle as the pregnancy advances from 1st to 3rd trimester increased length of abdominis $ diastasis compromises the functional abilities of pelvic stabilizers
  21. 1- of lower limb are also affected by ligament laxity promoted by hormone relaxin Postural deviations related to pregnancy impact the overloading in lower extremity joints in term of pain in knees sijoiunt hip these functional impairments are due to lenghtning of abd muscle that reduces the functional stability of hip joint Balance- due to joint & muscular overloads related to the increased body mass & superior & anterior displacement of centre of gravity 4-it is identified as pregnant women tried to maximize their postural stability & control with sideways movement by adjusting their step width this strategy requires the adoption of wwalking pattern that produces changes in joint segment & lower limb muscle which result in excessive plantar overload
  22. 1- all above mentioned postural modifications leads to compensatory mechanism in gait pattern which in turn overload the different segment of body & may lead to msk discomfort during child bearing year There is a biomechanical derangement of structures due to changes during pregnancy includes increase in weight & uterine growth which enhances the anterior loading of trunk & displaces the COG of body these changes results in greater oscillation of COP in anteroposterior direction leading to medio-lateral oscillation of COG - the main feature of change in gait also includes greater hip flex angle, greater hip ext angle hip abd moments & longer stance phase duration In addition to this there is reduction in plantar flexion & decreased propulsion forces leading to longer step length & width along with higher sways in both antero-posterior as well as medio-lateral this gait deviations results in redistribution of planter loads with oincreased loads on forefoot & decreased load in rear foot which is significantly prevalent during entire child bearing year
  23. 2-and information regarding access to further help if she is experiencing back pain or other physical discomfort For relive of pain gentle massage hot pack or tens should be provided During the third trimester of pregnancy, fluid retention can lead to oedema, which, as well as being visible in the ankles, feet, hands and face of the pregnant woman, can lead to reduced joint mobility and a variety of nerve compression syndromes-
  24. The increased weight during pregnancy thrusts the sacrum downwards between the ilia in all upright postures, and in walking, each sacroiliac joint alternately transmits the total loading. Is there a potential for the joint to fail as a result of joint laxity This usually disappears in a few months, but indicates transient stress. 2- A support belt may provide comfort for some women. Changes in orientation or degrees of movement at a sacroiliac joint may affect the symphysis pubis, and also the spine. It has also been shown that pain from the lumbar spine, and occasionally from the hip, may be referred to the sacroiliac region 1pic-the woman lying supine, and the knee of the affected side flexed, the toes are hooked under the lateral aspect of the straight knee. The therapist passively takes the flexed knee across the body while holding the shoulder of the affected side against the plinth. Thus tension is applied to the affected sacroiliac joint and any slack is ‘taken up’; at the end of range a single, gentle thrust is given. The woman may benefit from 2 pic -Hips 90* lower leg supported horizontally on even surface presses with the thigh against a firm surface hold and release -Side lying is usually the most comfortable resting position with a pillow between the knees
  25. The width of the symphysis pubis has been shown to increase asymptomatically in pregnancy from about 4.8 mm to 7-9mm The pain is described as a ‘burning’ or ‘bruised’ feeling in and around the joint, which may also radiate suprapubically and to the medial aspect of the thigh(s). Pain varies in severity and may be of gradual onset or incidious. It may be linked to a specific activity or a traumatic incident. It is provoked by weightbearing, especially unilateral, and hip abduction
  26. – calcium deficiency, ischaemia and nerve root pressure among them. Towards term, increased fluid retention together with reduced activity, particularly in the evenings, may be an additional factor. The technique of stretching in bed with the foot dorsiflexed and not plantar flexed for preventing and easing calf cramp should also be shown. Additional suggestions for cramp relief include avoiding long periods of sitting, a pre-bedtime walk, calf stretches, a warm bath, and foot and ankle exercises in bed before going to sleep.
  27. Caution should be taken in the 1st trimester when stretching add Stretch add is by unilateral slow & genbtle using contract relax Prior to prescribe the hip add length
  28. Streghtening of ER Corner press outs
  29. Posterior tilting is emphasized to improve posture as anterior tilting of pelvis is adopted during pregnancy -pelvic tilting exercises can be taught by sitting on the edge of the chair & then progressed in crook lying prone kneeling, side lying & standing -it includes isometric abdominalis bridging , cat camel, heel slides maintaining posterior tilting & posterior tilting using physioball -It is helpful in postural correction, maintaining transversus abdominus strength & easing back ache –pelvic floor contraction is taught by asking the women to draw the pelvic floor up & into the pelvis & maintain 6-8 sec hold then relax Women should be encouraged to increase both the length of contraction & no of reps as streght & endurance increases
  30. 1- all four rectus/ transverse abdominis, external/internal oblique, The mother is in crook lying positionwith pelvis in posterior tilt –while maintaining women is asked to slide one foot until the leg is straight These are some exercises to prevent diastasis recti of rectus abdominus muscle the belly od rectus frequently gets separated at linea alba during pregnancy predisposing factors- a large fetus, multiple pregnancies,excessive amniotic fluid,obesity Head lift- crook lying-hands crossed-liftes head off the floor while exhaling & pulls the rectus mucle with with hand -lower head inhales Spinal-considering the fact during child bearing year it is imp to focus on activating deep local muscle as early rehab by incorporating the cocontraction of transverse abdominis & multifidus -should involve prophylactic program to avoid major lbp related issues
  31. Sit-feet flat on floor hips knees @ right angle using foot rest lumbar lordosis should be well supported using cushion Lying- sleeping on left side with knees slightly bend & pillow in between Stand-encourage to hold her head up with chin tuck in & shoulder blades pilled backward with chest forward avoid knees in hyperextension & buttocks tucked in Gentle stretches with postural correction exercises to be practiced Emphasize the relaxation technique to reduce stress during pregnancy
  32. Mitchell-used for stress relieve strategy during first stage of labour as it provides physiological relaxation Stress relieveing is imp when they face Braxton hicks contraction This aapproch activates oly antagonist so it is an energy consevating method
  33. Tension relax technique activates agonist & antagonist muscle of body This strategy is max contraction of muscle is followed by max relaxation
