To diagnose a pregnant woman with pelvic pain, symptoms must be distinguished from lumbar pain first. Tests for the sacroiliac joint show good reliability to distinguish low back pain from sacroiliac joint pain.

If pain is evident in the sacroiliac joint, a combination of tests can be done to further exclude lumbar pain and other syndromes from the SIJ. A combination of the sacral sulcus tenderness test (or palpation of the long dorsal ligaments) and the pointing to the spina iliaca posterior superior (SIPS) test (or pointing to the joint test) have the best predictive value for pelvic pain. Two more sensitive tests are palpation of the symphysis and painful femoral compression, these two tests are also called posterior pelvic pain provocation test.

== Differential Diagnosis ==
Diagnosis of pelvic pain in women can be challenging because many symptoms and signs are insensitive and nonspecific. As the first priority, urgent life-threatening conditions (e.g., ectopic pregnancy, appendicitis, ruptured ovarian cyst, ovarian vein thrombosis, placental abruption) , fertility-threatening conditions (e.g. pelvic inflammatory disease, ovarian torsion, endometritis), painful visceral pathologies of the pelvis (urogenital and gastrointestinal), lower-back pain syndromes (e.g. lumbar disc-lesion, rheumatism or sciatica) , bone or soft tissue infections, urinary tract infections, femoral vein thrombosis, rupture of symphysis pubis and bone or soft tissue tumors must be considered.<ref name="KANA" /><ref name=":12">Morgen, IM. et al; Low Back Pain and Pelvic Pain During Pregnancy: Prevalence and Risk Factors; Spine; 2005 April; pp 983-991 </ref>
The most common urgent causes of pelvic pain are pelvic inflammatory disease, ruptured ovarian cyst, and appendicitis; however, many other diagnoses in the differential may mimic these conditions, and imaging is often needed. Transvaginal ultrasonography should be the initial imaging test because of its sensitivities across most etiologies and its lack of radiation exposure. A high index of suspicion should be maintained for pelvic inflammatory disease when other etiologies are ruled out, because the presentation is variable and the prevalence is high. Multiple studies have shown that 20 to 50 percent of women presenting with pelvic pain have pelvic inflammatory disease. Adolescents, pregnant and postpartum women require unique considerations.<ref>Morino M, Pellegrino L, Castagna E, Farinella E, Mao P. Acute nonspecific abdominal pain: A randomized, controlled trial comparing early laparoscopy versus clinical observation. Ann Surg. 2006;244(6):881–888. (: 2A)</ref>
The differential diagnoses of low back pain and pelvic girdle pain is very similar. PGP is mostly located between the posterior iliac crest and the gluteal fold near the sacroiliac joints, it has possible symphysis dysfunction. Pain is intermittent and may be provoked by daily activities such as walking, sitting or standing. A careful medical history focusing on pain characteristics is necessary to make a definitive diagnosis. The patient should be asked about the location, intensity, radiation, timing, duration, and exacerbating and mitigating factors of the pain. Review of systems, gynecologic, sexual, and social history, in addition to physical examination and an appropriate laboratory test, helps to narrow the differential diagnosis.<ref name=":4" />

The description with what the patient feels is important to know. Like a “catching feeling when walking” is often a sign of posterior pelvic pain, but further test need to be performed to see if it is really a posterior pelvic pain.<ref name=":1">Sturesson et al; Pain pattern in pregnancy and" catching" of the leg in pregnant women with posterior pelvic pain; Spine; 1997; PP 1880-1883 </ref> It is also very important to ask the patient about his pain history.

Description[edit | edit source]

Pregnant cross-section.jpg

According to the European guidelines created by Vleeming and colleagues,[1]Pelvic girdle pain (PGP) generally arises in relation to pregnancy, trauma, arthritis and osteoarthritis. Pain is experienced between the posterior iliac crest and the gluteal fold, particularly in the vicinity of the sacroiliac joints (SIJ). The pain may radiate in the posterior thigh and can also occur in conjunction with/or separately in the symphysis.”[1]

Clinically Relevant Anatomy[edit | edit source]

The pelvis is composed of the sacrum, ilium, ischium and pubis. The pelvic bone consists the pubic symphysis and the sacroiliac joint.

Sacroiliac Joints
The sacroiliac joints allow for the transfer of forces between the spine and the lower extremity.[2] To read more about the function of the sacroiliac joints review: Force and Form Closure

Pelvic Floor
The pelvic floor muscles have two primary functions in females. The muscles:[3]

  1. support the abdominal viscera (bladder, intestines, uterus) and the rectum
  2. control the mechanism for continence for the urethral, anal and vaginal orifices[3]

Epidemiology /Etiology[edit | edit source]

Pelvic girdle pain may begin around the 18th week of pregnancy and appears to peak between the 24th and 36th week.[4] Pelvic pain affects approximately 50% of women during pregnancy.[5] 25% of the women who experience pelvic girdle pain report having severe pain and 8% report pain that causes severe disability.[6]

The etiology of pregnancy-related pelvic girdle pain has not been clearly established in the literature.[7] However, the cause of this pain is believed to be multi-factorial and may be related to hormonal, biomechanical, traumatic, metabolic, genetic and degenerative factors.[8] [9] [10]

Hormonal[edit | edit source]

Women produce increased quantities of the hormone relaxin during their pregnancy. Relaxin increases ligament laxity in the pelvic girdle (and in other parts of the body) in preparation for the labour process. Increased ligament laxity may cause a small increase in the range of motion at the pelvis. If this increase in motion is not complimented by a change in neuromotor control (e.g., muscles around the pelvis act to improve stability), it is possible that pain may occur.[1] However, the link between relaxin and pelvic girdle pain during pregnancy has not been established in the literature.[9][10] Research to date also does not support the idea that an increase in the range of motion at the pelvis causes pain.[1][11] [12]

Biomechanical[edit | edit source]

As pregnancy progresses, the gravid uterus increases load on the spine and pelvis. To accommodate for the growth of the uterus the pubic symphysis must soften and laxity in the pelvic ligaments increases. The uterus shifts forward which changes the maternal centre of gravity and the orientation of pelvis.[13] This change in centre of gravity may cause stress or a change in load on the lower back and pelvic girdle.[9][14][10] This change in load can result in compensatory postural changes (e.g., an increase in lumbar lordosis).[9][14][10]

Risk Factors[edit | edit source]

The risk factors for developing pregnancy-related pelvic girdle pain are:

  • a previous history of low back pain or pelvic girdle pain.[15][10]
  • a previous trauma to the pelvis or back.[15][10]
  • physical demanding work (e.g., twisting and bending the back several times per hour per day).[1][5][16][17][18]
  • multiparity - may play a causal role in the development of pregnancy-related pelvic girdle pain[19]

Characteristics/Clinical Presentation[edit | edit source]

The clinical presentation of pregnancy-related pelvic girdle pain can vary from patient to patient and can change over the course of the patient's pregnancy.[5]

Pain[edit | edit source]

The onset of pain may occur around the 18th week of pregnancy and reaches peak intensity between the 24th and 36th week of pregnancy. The pain typically resolves by the third month in the postpartum period.[20][10]

Location[edit | edit source]

Pelvic girdle pain typically presents near the sacroiliac joints and/or gluteal area or anteriorly near the symphysis pubis[5]. The reported pain may radiate into the patient's groin, perineum or posterior thigh but does not mimic a typically sciatic nerve root distribution.[21][22] The location of the pain may vary throughout the course of the pregnancy.[23]

Nature and intensity of pain[edit | edit source]

Pelvic girdle pain may be described as a stabbing[24][25], dull, shooting or burning sensation.[25] The intensity of pain on a 100 mm visual analogue scale averages around 50-60 mm.[23][22]

Muscle Function and Perception[edit | edit source]

  • postpartum women may present with reduced hip abduction and adduction force[26] which may be related to fear of pain/movement.[26]
  • women may reported a feeling of "catching" in their upper leg during ambulation[25] and/or report feeling the lack the ability to move their legs during the active straight leg test[27] which may suggest nervous system involvement.[5]
  • altered gait coordination- women with postpartum pelvic girdle pain can present with a coupling between pelvic and thoracic rotations during gait (pelvic and thoracic rotations in the same direction occur at the same time) which has been proposed as a nervous system strategy used to cope with motor problems.[28]

Diagnostic Procedures[edit | edit source]

To diagnose a pregnant woman with pelvic pain it is important to rule out lumbar pain/involvement first. Tests for the sacroiliac joint show good reliability to distinguish low back pain from sacroiliac joint pain. A precise pain location of the provoked pain must be obtained for the test to have enough specificity.[29] Further diagnosis can be reached from signs and symptoms experienced and described by the pregnant women.

Common symptoms related to pregnancy-related pelvic pain include:

  • a difficulty walking quickly and covering long distances[1][30][5]
  • pain/discomfort/difficulty during sexual intercourse[30][5]
  • pain/discomfort during sleep and/or a difficulty turning over in bed[5][31]
  • decreased ability to perform housework[5][31]
  • decreased ability to engage in activities with children[5]
  • difficulty sitting[31]
  • difficulty standing for 30 minutes or longer[31]
  • pain in single leg stance i.e., climbing stairs[31]
  • inability or difficulty running (postnatal) due to pain[31]
  • decreased ability for mother-child interactions[16]
  • pain/discomfort with weight bearing activities[14]

If pain is evident in the sacroiliac joint, a combination of tests can be done to further exclude lumbar pain and other syndromes from the SIJ. A combination of the sacral sulcus tenderness test (or palpation of the long dorsal ligaments) and the pointing to the spina iliaca posterior superior (SIPS) test (or pointing to the joint test) have the best predictive value for pelvic pain. Two more sensitive tests are palpation of the symphysis and painful femoral compression, these two tests are also called posterior pelvic pain provocation test. The posterior pelvic pain (PRPP) provocation test and Patrick’s/Faber Test (flexion, abduction and external rotation) show high sensitivity if pain is evident in the SIJ.[29][32][33]

Other diagnostic tests and imaging for pregnancy related pelvic girdle pain:

  • Urinalysis, midstream specimen of urine (MSU).
  • High vaginal swab (HVS) for bacteria and endocervical swab.[1]
  • Pregnancy test.
  • MRI (most suggested imaging modality to evaluate PGP)[17]
  • Ultrasonography[17]
  • FBC/A full blood count: this is a very common blood test and is used to check a person's general health as well as screening for specific conditions. The number of red cells, white cells and platelets in the blood are checked.
  • Urgent ultrasound (if miscarriage or ectopic pregnancy is suspected).
  • Laparoscopy[34]

Examination[edit | edit source]

The description with what the patient feels is important to know. Like a “catching feeling when walking” is often a sign of posterior pelvic pain, but further test need to be performed to see if it is really a posterior pelvic pain.[25] It is also very important to ask the patient about his pain history. The use of a pain location diagram is strongly recommended, so that we can be sure that the pain is localized in the pelvic area. The patient may also point out the pain location on his or her body.[1][35]

The following tests are recommended for the clinical examination, to make the diagnosis of pelvic girdle pain:

For SIJ pain:

Symphysis :

Functional pelvic test:

Joint examination:[29]

  • Spine
  • Pelvic girdle
  • Hip
  • Assessment of the nerves supplying the muscles[29]
  • Assessment of functional abilities[29]

Radiological investigations also have an essential role in the evaluation of PGP. Standard anteroposterior, inlet and outlet pelvic films are used to measure the degree of symphyseal separation. PGP syndrome leads to the separation of the symphysis pubis in pregnant women, which result in a higher degree. The use of flamingo can be useful in quantifying the degree of pelvic girdle instability.[30]

Differential Diagnosis[edit | edit source]

Diagnosis of pelvic pain in women can be challenging because many symptoms and signs are insensitive and nonspecific. As the first priority, urgent life-threatening conditions (e.g., ectopic pregnancy, appendicitis, ruptured ovarian cyst, ovarian vein thrombosis, placental abruption) , fertility-threatening conditions (e.g. pelvic inflammatory disease, ovarian torsion, endometritis), painful visceral pathologies of the pelvis (urogenital and gastrointestinal), lower-back pain syndromes (e.g. lumbar disc-lesion, rheumatism or sciatica) , bone or soft tissue infections, urinary tract infections, femoral vein thrombosis, rupture of symphysis pubis and bone or soft tissue tumors must be considered.[30][35]

The most common urgent causes of pelvic pain are pelvic inflammatory disease, ruptured ovarian cyst, and appendicitis; however, many other diagnoses in the differential may mimic these conditions, and imaging is often needed. Transvaginal ultrasonography should be the initial imaging test because of its sensitivities across most etiologies and its lack of radiation exposure. A high index of suspicion should be maintained for pelvic inflammatory disease when other etiologies are ruled out, because the presentation is variable and the prevalence is high. Multiple studies have shown that 20 to 50 percent of women presenting with pelvic pain have pelvic inflammatory disease. Adolescents, pregnant and postpartum women require unique considerations.[38]

The differential diagnoses of low back pain and pelvic girdle pain is very similar. PGP is mostly located between the posterior iliac crest and the gluteal fold near the sacroiliac joints, it has possible symphysis dysfunction. Pain is intermittent and may be provoked by daily activities such as walking, sitting or standing. A careful medical history focusing on pain characteristics is necessary to make a definitive diagnosis. The patient should be asked about the location, intensity, radiation, timing, duration, and exacerbating and mitigating factors of the pain. Review of systems, gynecologic, sexual, and social history, in addition to physical examination and an appropriate laboratory test, helps to narrow the differential diagnosis.[17]

Physical Therapy Management[edit | edit source]

Physical therapy for pelvic girdle pain during pregnancy[edit | edit source]

According to the European guidelines by Vleeming and colleagues[1] exercises are recommended during pregnancy. These exercises should focus on adequate advice concerning activities of daily living and avoid maladaptive movement patterns.[1] It is important to follow an individualized program, focusing specifically on stabilizing exercises for a greater control.

Physical therapy for pelvic girdle pain after pregnancy[edit | edit source]

After pregnancy, it is also important to focus on specific stabilizing exercises. It has been proven that this type of exercises have a positive effect on pain, functional status and health-related quality of life.[1][17]
The treatment program actually includes several important factors like [36] :

  • Advice and education: Informing the patient about body awareness. The purpose of information is mainly to reduce fear and to encourage patients to take an active part in their treatment and/or rehabilitation. General information on PGP needs to be presented (anatomy, biomechanics, motor control) and the patients need to be reassured that their problems are not dangerous to them or their child and that they will probably improve/recover. Ergonomic advice in real life situations can also be helpful, these situations can be really specific like carrying or lifting a child. The patient needs to be encouraged to enjoy physical activity and manage and combine this with periods of rest in order to recuperate.[1]
  • Joint mobilization, massage, relaxation and stretching can be executed when indicated. Manipulation or joint mobilization may be used to test for symptomatic relief, but should only be applied for a few treatments. Adjusting asymmetrical motion of the SIJs prior to exercising with joint mobilization may influence optimal form closure and enhance the possibility to exercise without pain. Massage might be helpful, but it must be given as part of a multifactorial individualized treatment program.[19] Manual therapy could be applied even though the evidence is conflicting.[29][39]
  • Exercises to retrain motor control and strength of abdominal, spinal, pelvic girdle, hip and pelvic floor muscles.[29] Giving the patients specific stabilizing exercises can reduce pain intensity, lower disability and higher quality of life.[40]
  • Pain control: Exercise in water can help.[29] Conflicting evidence shows that acupuncture could relieve pain.[41] Massage and osteo manipulative therapy can also help to reduce pain during pregnancy but further research is required.[42][43] Craniosacral therapy has small pain-relieving effects. If it’s used in combination with standard treatment it diminishes morning pain and gives less deteriorated function. But it’s not recommended for pregnant women since the effect are clinically very small.[44] TENS is a safe way to help patients with pain relief.[45]

The program, for exercise and training, consists of:[17]

  • Specific training of the abdominal muscles, which are transversely oriented. This must be performed with co-activation of the lumbar multifidus at the lumbosacral region.
  • The following muscles will be trained: Gluteus maximus, latissimus dorsi, blique abdominal muscles, erector spinae, quadratus lumborum and the hip adductors and abductors.

In the initial stage, the treatment program focuses on the training of specific contractions of the deep muscle system, independently from the superficial muscle. The deep muscle system consists of transversus abdominis, obliquus internus, multifidus, pelvic floor and the diaphragm. During all exercises and daily activities they emphasize the importance of activating these muscles before adding the superficial muscles. Depending on clinical findings this focus was combined with information, ergonomic advice, body awareness training, relaxation of global muscles and mobilization.[17][40] Exercises for the superficial muscles were gradually added to the program, when low force contractions of the transversely oriented abdominal muscles were achieved.[40]

The Therapy Master, which is an exercise device, can be utilized to facilitate the exercise progression for most of the exercises.[17][40] In literature, the patients performed these exercises 30 to 60 minutes, 3 days a week, and this for 18 to 20 weeks. They also started with three series of ten repetitions of each exercise.[17] The quality of the execution of the exercise determined the number of exercises and number of repetitions. Each patient received specific stabilizing exercises out of a fixed menu (see photo). The patients may have muscle soreness, but the exercises may not provoke pain at any time. It’s also very important that the patient maintains lumbopelvic control during the performance of these exercises.[17][40] The exercises for enhancing the lumbopelvic control and stability should involve the entire spinal musculature. Focusing on only global muscles seems insufficient.[19]

Patients often have a flare-up of pain when exercising, but this is likely from progressing the exercise load too quickly. This study used an exercise diary so the patient could describe her progression, and seemed to be effective in avoiding flare-ups.[17] It is well documented that exercise supervision is critical for improving quality of exercise performance.[17][40]

Outcome Measures[edit | edit source]

Pelvic Girdle Questionnaire (PGQ)[46]

Prognosis[edit | edit source]

Pregnancy-related pelvic girdle pain appears to be a self-limiting condition that typically resolves by 3 months postpartum in a majority of women.[10] However, due to the complexity of the condition it has been recommended that a biopsychosocial approach aimed at improving the individual's self-knowledge and self-efficacy be used in the management of pelvic girdle pain to help minimize disability.[47]

Medical Management[edit | edit source]

Medical therapy for pelvic girdle pain during pregnancy[edit | edit source]

  • Intra-articular SIJ injections (under imaging guidance) for ankylosing spondylitis can be recommended. But high quality studies are required for SIJ therapeutic injection therapy.[1]
  • Taking simple analgesia (paracetamol)[29]
  • Low potency opiates like codeïne and dihydrocodeine[29]
  • Avoiding non-steroidal anti-inflammatory drugs (NSAID) during pregnancy[29]
  • The use of a pelvic belt has shown to relieve the pain in many patients. Coxal and femur compression deactivated some dorsal hip muscles, reduced vertical SIJ shear forces and increased SIJ compression. This enhanced SIJ stability.[48]
  • Acetaminophen in oral or rectal form in cases of mild pelvic pain[17]
  • Low-dose aspirin is considered safe during pregnancy[17]
  • Cyclobenzaprine, a muscle relaxant[17]
  • Opioids may be used on short-term and small dose for severe pain[17]
  • Surgery can be performed during pregnancy if the pain is having a disabling, paralysing effect or if neurologic compromise is highly probable, although surgery is considered to have a limited role in PGP.[17]

Medical therapy for pelvic girdle pain after pregnancy[edit | edit source]

  • Different guiding techniques for intra-articular injections in the SIJ were used either under fluoroscopy or with CT or MRI guidance, this showed immediate pain relief with decreasing effects over time.[1]
  • The use of a pelvic belt may reduce mobility/laxity of the SIJ. Effective load transfer through the pelvis, has been improved by the application of a pelvic belt. It has a positive effect on pain and daily activities. A pelvic belt may also be fitted to test for symptomatic relief, but should only be applied for short periods.[1][48]

Clinical Bottom Line[edit | edit source]

We can conclude that pregnancy related pelvic girdle pain often is caused by instability of the pelvis or sacroiliac joint. Biomechanical (the wedge shape of the sacrum, the additional compression forces which are generated by the muscles, fascia and ligaments) and hormonal (relaxin, progesterone) factors have an impact on the dynamic stability. These factors can cause an increased motion of the pelvic joints which leads to a stabbing pain deep in the sacral/gluteal region. Patients who suffer from pelvic girdle pain, have difficulty during walking, running, climbing stairs, sexual intercourse and also during sitting and sleeping.

To make the diagnosis of pelvic girdle pain the following tests are recommended for the clinical examination: posterior pelvic pain provocation test , Patrick ‘s Faber test, palpation of the long dorsal SIJ ligament , Gaenslen’s test, palpation of symphysis, modified Trendelenburg’s of the pelvic girdle and the active straight leg raise test (ASLR test). It’s also very important to ask the patient about his pain history.

During and after pregnancy it is important to follow an individualized program, in which stabilization exercises are very important. During this program it is important to focus on adequate advice concerning activities of daily living and to avoid maladaptive movement patterns. The following muscles need to be trained during the exercise program: the abdominal muscles, M. gluteus maximus, M. latissimus dorsi, M. oblique abdominal muscles, M. erector spinae, M. quadrates lumborum end the hip adductors and abductors.
