"The classification between hormonal and mechanical pelvic girdle instability is no longer used. For treatment and/or prognosis it makes no difference whether the complaints started during pregnancy or after childbirth." Mens (2005)

Symptoms

A combination of postural changes, the growing baby, unstable pelvic joints under the influence of pregnancy hormones and changes in the centre of gravity can all add to the varying degrees of pain or discomfort. In some cases it can come on suddenly or following a fall, sudden abduction of the thighs (opening too wide too quickly)or an action that has strained the joint.

PGP can begin as early as the first trimester of pregnancy. Pain is usually felt low down over the symphyseal joint, and this area may be extremely tender to the touch. Pain may also be felt in the hips, groin and lower abdomen and can radiate down the inner thighs. Women suffering from PGP may begin to waddle or shuffle, and may be aware of an audible clicking sound coming from the pelvis. PGP can develop slowly during pregnancy, gradually gaining in severity as the pregnancy progresses.

During pregnancy and postpartum, the symphyseal gap can be felt moving and/or straining when walking, climbing stairs and turning over in bed. These activities can be difficult or even impossible. Pain may remain static, i.e. in one place such as the front of the pelvis producing the feeling of having been kicked, in other cases it may start in one area and move to other areas, you may even experience a combination of symptoms. Any weight bearing activity has the potential of aggravating an already unstable pelvis producing symptoms that may limit the ability for the woman to carry out many daily activities. She will experience pain involving movements such as dressing, getting in and out of the bath, rolling in bed, climbing the stairs and sexual activity. Pain will also be present when lifting, carrying, pushing or pulling.

The symptoms (and their severity) experienced by women with PGP vary, but include:
  • Present swelling and/or inflammation over joint.
  • Difficulty lifting leg.
  • Pain pulling legs apart.
  • Inability to stand on one leg.
  • Inability to transfer weight through pelvis and legs.
  • Pain in hips and/or restriction of hip movement.
  • Transferred nerve pain down leg.
  • Can be associated with bladder and/or bowel dysfunction.
  • A feeling of symphysis pubis giving way.
  • Stooped back when standing.
  • Malalignment of pelvic and/or back joints.
  • Struggle to sit or stand.
  • Pain may also radiate down the inner thighs.
  • Waddling or shuffling gait.
  • Audible ‘clicking’ sound coming from the pelvis.

Severity

The severity and instability of the pelvis can be measured on a three level scale.

Pelvic type 1:The pelvic ligaments support the pelvis sufficiently. Even when the
muscles are used incorrectly, no complaints will occur when performing everyday activities. This is the most common situation in persons who have never been pregnant, who have never been in an accident, and who are not hyperactive.

Pelvic type 2:The ligaments alone do not support the joint sufficiently. A
coordinated use of muscles around the joint will compensate for ligament weakness. In case the muscles around the joint do not function, the patient will experience pain and weakness when performing everyday activities. This kind of pelvic often occurs after giving birth to a child weighing 3000 grams or more, in case of hyperactivity, and sometimes after an accident involving the pelvis. Type 2 is the most common form of pelvic instability. Treatment is based on learning how to use the muscles around the pelvis more efficiently.

Pelvic type 3:The ligaments do not support the joint sufficiently. This is a serious
situation whereby the muscles around the joint are unable to compensate for ligament weakness. This type of pelvic instability usually only occurs after an accident, or occasionally after a (small) accident in combination with giving birth. Sometimes a small accident occurring long before giving birth is forgotten so that the pelvic instability is attributed only to the childbirth. Although the difference between Type 2 and 3 is often difficult to establish, in case of doubt an exercise program may help the patient. However, if Pelvic Type 3 has been diagnosed then invasive treatment is the only option: in this case parts of the pelvis are screwed together. (Mens 2005)

Psychosocial impact

PGP in pregnancy seriously interferes with participation in society and activities of daily life; the average sick leave due to posterior pelvic pain during pregnancy is 7 to 12 weeks.

In some cases women with PGP may also experience emotional problems such as anxiety over the cause of pain, resentment, anger, lack of self-esteem, frustration and depression

  2. A change in the activity of the muscles in the pelvis, hip

". The step lengthens as the pregnancy progresses due to weight gain and changes in posture. Both the length and height of the footstep shortens with PGP. Sometimes the foot can turn inwards due to the rotation of the hips when the pelvic joints are unstable. On average, a woman's foot can grow by a half size or more during pregnancy. Pregnancy hormones that are released to adapt the bodily changes also remodel the ligaments in the foot. In addition, the increased body weight of pregnancy, fluid retention and weight gain lowers the arches, further adding to the foot's length and width. There is an increase of load on the lateral side of the foot and the hind foot. These changes may also be responsible for the musculoskeletal complaints of lower limb pain in pregnant women.

During the motion of walking, an upward movement of the pelvis, one side then the other, is required to let the leg follow through. The faster or longer each step the pelvis adjusts accordingly. The flexibility within the knees, ankles and hips are stabilized by the pelvis. Normal gait tends to minimize displacement of centre of gravity whereas abnormal gait through pelvic instability tends to amplify displacement. During pregnancy there may be an increased demand placed on hip abductor, hip extensor, and ankle plantar flexor muscles

Self help management

Self help management techniques include:
  • When getting into bed sit on the edge keeping knees close together, lie down on your side, lifting both legs at the same time. Reverse this to get up.
  • Try not to attempt to pull yourself up from lying on your back.
  • Keep knees together when rolling over in bed.
  • Sleep with a pillow between the legs; add more in other areas for support.
  • When getting into a car: Sit down first and then swing legs keeping them together.
  • Avoid sofas and chairs that are too low or too soft.
  • Try to reduce the stress on the joint.
  • Avoid any movement with your knees apart.
  • Take smaller steps when walking.
  • Avoid stairs if possible.
  • Take breaks.
  • Move within the limits of pain.
  • Avoid twisting, bending or squatting.

 activities. PGP can take from 11 weeks, 6 months or even up to 2 years postpartum to subside. However, some research supports that the average means to complete recovery is 6.25 years, and the more severe the case is, the longer recovery period.

Overall, about 45% of all pregnant women and 25% of all women postpartum suffer from PGP. During pregnancy, serious pain occurs in about 25%, and severe disability in about 8% of patients. After pregnancy, problems are serious in about 7%. There is no correlation between age, culture, nationality and numbers of pregnancies that determine a higher incidence of PGP.

If a woman experiences PGP during one pregnancy she is more likely to experience it in subsequent pregnancies; but the severity cannot be determined.
