Why Therapeutic Exercise for Pregnant Women?
Primary conditions unrelated to pregnancy
Disorders related to physiologic changes during pregnancy
Physical and psychological benefits
Preventative measures

Physiologic Changes Related to Pregnancy – Support Element
Endocrine system – Alterations in hormone levels, GI function, etc.
CV system – Changes in blood volume, hemoglobin levels, vasodilation.
Respiratory system – Increased mucus in respiratory tract, predisposition to coughing, sneezing if pelvic floor and associated muscles are weak.

Physiologic Changes Related to Pregnancy Base Element
Musculoskeletal symptoms should not be considered normal.
COG shifts forward and upward (lumbar lordosis, forward head posture, rounded shoulders, etc).
Changes in hormone – Joint laxity (increased foot pronation).

Therapeutic Exercise Intervention for Wellness
Moderate aerobic exercise (carefully monitored and prescribed) is safe and beneficial for the
mother and fetus.

Exercise Intensity Guidelines
In pregnancy, maternal resting HR is elevated over nonpregnant values by 15–20 bpm.
Mitral valve prolapse occurs more frequently during pregnancy and may be aggravated by heart rates above 140 bpm.
Therefore, reduce exercise intensity by 25% to 60–75% to be safe.
A maximum HR of 140 bpm for novice exercisers and 160 bpm for experienced exercisers.

Therapeutic Exercise for Common Impairments

Adjunctive Interventions
Hot packs – Safe for back, neck,and extremities.
Ultrasound – Sites away from uterus.
Ice – Used on joint pain and inflammation.
NMES/TENS – Contraindicated (except for TENS during labor and delivery).

Impaired Muscle Performance
Abdominal Strength
Goal – Improve muscle balance, posture, support of uterus via pelvic floor, stabilization of trunk
and pelvis via lumbopelvic core.

Exercise Examples
Supine hip and knee flexion with hip abduction and lateral rotation.
Progressive heel slides.
External oblique exercises to counter anterior pelvic tilt in variety of positions.
Concentric and eccentric abdominal
contractions in quadruped.

Pelvic Floor Strength
Importance cannot be overemphasized!
Attention to pelvic floor strength should occur early
in the pregnancy and continue throughout the duration
and into postpartum.

Impaired Joint Integrity and Muscle Length
Joint Hypermobility
Greater degree of joint laxity throughout the body during
pregnancy.
Copyright 2005 Lippincott Williams & Wilkins
Abdominal Muscle Length
External/internal oblique, transversus abdominis, rectus abdominis – all lengthen.
Rectus muscles separate in midline, creating diastasis recti.

Diastasis Recti
Copyright 2005 Lippincott Williams & Wilkins
Corrective Exercise
1. Patient manually approximates recti muscles toward midline.
2. Performs a posterior pelvic tilt.
3. Slowly exhale while lifting head.

Correction of Diastasis Recti

Pelvic Floor Muscle Length
If coccyx pain is related to pelvic floor tension myalgia, pelvic floor relaxation
must be emphasized.
1. Place hand over anal cleft.
2. Place middle finger in cleft and other fingers on buttocks.
3. Pretend to “pass gas” while feeling for cleft bulging out against middle finger.

Impaired PostureBiomechanical Element
Restore ideal alignment
1. Lordosis intervention - Frequent inner core activation in various positions.
2. Wall abdominal isometrics.
3. Kyphosis intervention – Facilitate strengthening to scapular upward rotators, thoracic erector spinae, stretch pectoral muscles.
Copyright 2005 Lippincott Williams & Wilkins
PainCauses Include:
Biomechanical strain from increased body mass and dimension. Postural changes such as lumbar lordosis creating joint stress. Aggravation of preexisting conditions. Muscle fatigue from overload, particularly pelvic floor.
Pregnant Woman are particularly susceptible to: Lumbar pain Posterior pelvic pain Nocturnal back pain

High Risk Antepartum
20% of all pregnancies include bedrest prescription.
Woman who delay childbearing may expect a higher incidence of obstetric complications resulting in bedrest.
General strengthening, circulation exercises, and relaxation exercises are indicated to prevent secondary conditions as a result of bedrest.

Therapeutic Exercise Considerations
Improve circulationPromote relaxationAvoid increased intra-abdominal pressure by
minimizing abdominal contractions during exercise and ADLs.
Prevent decreased muscle tone and deconditioning.
Prevent neuromuscular discomfort.

Therapeutic Exercise Intervention for Common Impairments
Nerve Compressive Syndromes
Common during pregnancy due to:• Fluid retention• Edema• Soft tissue laxity• Exaggerated postural changes
Copyright 2005 Lippincott Williams & Wilkins
Common Nerve Compression Syndromes
Intercostal neuralgiaThoracic outlet syndromeCarpal tunnel syndromeLateral femoral cutaneous nerve entrapmentTarsal tunnel syndromePeroneal nerve compression
Copyright 2005 Lippincott Williams & Wilkins
Intercostal Neuralgia
Described as intermittent pain in the rib cage or chest from flaring of the rib cage. Intervention includes spinal elongation with arms overhead in supine, sitting, or standing postions,
and trunk sidebending away from the pain.
Copyright 2005 Lippincott Williams & Wilkins
Thoracic Outlet Syndrome
1. Strengthening of upper back and scapular muscles.
2. Lengthening of pectoral muscles.
3. Support can be provided through good brassieres and manufactured supportive devices.
Copyright 2005 Lippincott Williams & Wilkins
Carpal Tunnel Syndrome
1. Decrease hand flexion activities.
2. Night splints.
3. Finger mobility exercises.
4. Look at scapula position and correct scapula depression.
Copyright 2005 Lippincott Williams & Wilkins
Lateral Femoral Cutaneous Nerve Entrapment
1. Exercises to balance hip muscles.
2. Lying on side to draw uterus away from compressed side.
3. Soft tissue mobilization techniques for IT band.
4. Strengthening for underused synergists to ITB (e.g., posterior gluteus medius).
Copyright 2005 Lippincott Williams & Wilkins
Tarsal Tunnel Syndrome
1. Elevation of foot and ankle.
2. Active foot and ankle exercises to reduce edema and compression.
3. Evening posterior splint.
Copyright 2005 Lippincott Williams & Wilkins
Peroneal Nerve Compression
Discourage prolonged squatting during
exercise and delivery.
Copyright 2005 Lippincott Williams & Wilkins
Other Impairments
Temporomandibular dysfunctionPatellofemoral dysfunctionJoint discomfort or dysfunctionVaricosis

Summary
Many physiologic changes that occur during pregnancy affect a woman’s ability and motivation to exercise.
Adherence to precautions, contraindications, guidelines, and a safe exercise program can be established for pregnant women.
Exercise during pregnancy has many benefits including prevention or assistance in treatment of impairments.

Summary (cont.)
Therapeutic exercise focuses on key postural muscles affected by changes during pregnancy.
High risk pregnancy may require bedrest.Specific exercises may be performed and are
beneficial for high-risk patients.Therapeutic exercise is beneficial postpartum,
even after cesarean section.
