Chiropractors see many causes of pelvic pain in pregnancy; symphysis pubis dysfunction(SPD) and diastasis symphysis pubis (DSP) are just two of them. Our treatment is very effective for pain relating to the spinal and pelvic joints and the treatment is particularly suitable for pregnant women since it is a safe and natural treatment. Chiropractic treatment does not promote the use of painkillers and non-steroidal anti-inflammatory medication (NSAID's) in pregnancy.
The quality of life for some women affected by SPD can be greatly diminished as it can affect their marriage, family relationships, sex life, social life and can cause employment and financial problems. They are often unable to lift their baby out of a cot because of the need for crutches just to be able to stand up. Some women end up in wheelchairs and feel cheated of the pleasure of being able to sit on the floor and play with their children.
Pelvic Dysfunction was described as early as 1870 by Snelling, he said: “The affection appears to consist of relaxation of the pelvic articulations, becoming apparent suddenly after parturition or gradually during pregnancy, and permitting a degree of mobility of the pelvic bones which effectively hinders locomotion and gives rise to the most peculiar, distressing and alarming sensations.”
It is important to have early treatment as the condition, can be severely disabling and early chiropractic treatment will reduce the risk of you becoming a chronic sufferer.
Pelvic dysfunction is not life threatening – but it can be life limiting!
What is Pelvic Dysfunction
The pregnancy hormone ‘relaxin’ softens and ‘relaxes’ the ligaments of the body in order to allow the pelvis to open slightly during labour. This is to help the baby move more easily through the pelvic canal. The levels of the hormone relaxin peak at around 12 weeks of pregnancy and therefore it is not uncommon for symptoms of pelvic dysfunction to occur around this time.
However, not all women suffer from pelvic pain during pregnancy, some only suffer post-natally, after giving birth. Some women will experience pelvic pain in their first pregnancy and not subsequently, while others will suffer from this distressing problem with each and every baby.
There are two conditions under the general term of Pelvic Dysfunction: Symphysis Pubis Dysfunction and Diastasis Symphysis Pubis. The symptoms are the same, so what is the difference?
Symphysis Pubis Dysfunction
This simply means that the joint at the front of the pelvis (the symphysis pubis) is not working as it should be. Together with the two large joints at the back of the pelvis (the sacroiliac, or SI joints), the symphysis pubis plays an important part in holding the pelvis steady during any activity, which involves the legs. If the joint is not firmly ‘tied’ by its ligaments it cannot perform its role effectively, resulting in excessive strain being placed on all the pelvic joints. This can give rise to the symptoms of SPD.
It is important to remember that as the hormones of pregnancy equally affect the sacroiliac joints, they too become slightly looser. It is therefore common for the problem to lie with one or both of the sacroiliac joints, with this putting extra stress on the symphysis pubis. In other words, the term SPD is flagging up the fact that the pelvic girdle is not functioning correctly, and unless an abnormal gap is definitely shown at the symphysis pubis (see diastasis symphysis pubis), the condition will be termed SPD.
The ‘Normal Gap’
The normal non-pregnant gap at the symphysis pubis (the distance between the two sides of the joint) is 4-5mm but in every pregnancy there will be an increase in this gap of at least 2-3mm. This is due to the fact that the ligaments that ‘tie’ the joint together become slacker under the influence of the pregnancy hormones. Therefore, it is considered that a total width of up to 9mm between the two bones is normal for a pregnant woman.
Following delivery, this natural extra gapping decreases within days although the supporting ligaments will take 3 to 5 months to fully return to their normal state to make the symphysis pubis a strong joint again.
Diastasis Symphysis Pubis
DSP means an abnormally wide gap is present between the two pubic bones at the symphysis pubis, diagnosed conclusively by investigation such as x-ray (post-partum), ultrasound or an MRI scan (magnetic resonance imaging). An abnormal gap is considered to be 10mm or more, sometimes with the two bones being slightly out of alignment. This abnormal gap remains evident after the time that the joint should have regained the normal non-pregnant width.
What Causes SPD?
The most popular view is that SPD occurs simply as a result of the pregnancy hormones, causing a laxity of the pelvic ligaments, which then no longer hold the joint steady with movements of the legs. It is sometimes thought that women whose joints are more flexible before pregnancy may be more susceptible to the effect of hormones during pregnancy.
Another theory is that the cause of SPD is hormonal in conjunction with biomechanical – the fact that the pelvic girdle has to carry an expanding uterus and growing foetus. Some also believe that SPD is primarily a problem of misalignment of the pelvis, leading to extra pressure on the cartilage of the symphysis pubis, and leading to the belief that the first line of treatment of SPD should be to address the possibility of pelvic misalignment.
Other Risk factors
Other risk factors of developing SPD include:
- Multiparity (more than one pregnancy)
- Having large babies
- Pre-existing symphysis pubis problems
- Past pelvic / sacroiliac / low back pain
- Past trauma (car accident, obstetric trauma, etc.) that may have damaged the pelvic girdle area.
Symptoms of SPD
These vary with the severity of the condition and symptoms will be experienced differently for every woman. It has been found that the severity of the symptoms does not relate to the degree of separation at the symphysis pubis joint and therefore, in the presence of pain, a separation between 5 and 9mm is diagnostic.
The pain may remain static, i.e. in just one place such as the front of the pelvis, or in other cases it may start in one area and move to other areas. It is likely that you will experience a combination of the symptoms. These include:
- Pain over the symphysis pubis joint
- Pain described as a deep bruising, burning or stabbing pain
- Tender to touch – having the fundal height measured may be painful
- Lower back pain, especially in the sacroiliac area
- Hip, groin and lower abdominal pain
- Reduced hip range of motion, abduction (moving out to the side) especially painful
- Radiating pain to the inner thigh
- Waddling / shuffling gait
- Increased pubic pain on normal activity, e.g. walking, parting and lifting the legs
- Audible clicking / grinding sound coming from the pelvis (at the symphysis pubis)
- Bladder dysfunction (temporary incontinence with changes in position)
Because the pelvis serves as an anchoring point for many of our muscles and the pelvic joints play an important role in weight bearing activities, chiropractors often hear from their patients that they have a difficulty with: Rolling over in bed Going up or down stairs Getting in and out of cars Sitting down / getting up Putting on clothes Bending Lifting / standing on one foot Lifting heavy objects Getting moving, especially after sleep Getting in / out of the bath Difficulty walking with a long stride.
When does the pain of SPD usually start?
The pain of symphysis pubis dysfunction often comes on early in pregnancy, even as early as 12 weeks, when the level of the hormone ‘relaxin’ increases.
The pain can develop slowly, gradually gaining in severity as the pregnancy progresses, owing to postural changes and the change in centre of gravity, the growing baby, and the increasingly unstable pelvis.
In some cases the pain can come on suddenly, e.g. after a fall or sudden separation of the thighs (too wide too quickly).
It is important to ask for help and accept help at every opportunity. The key points to remember are:
- Take tiny steps to go upstairs one at a time, setting off with your better leg if you have one and bringing the second leg to meet the first before going up another step. Walking sideways upstairs is often easier!
- Use a pillow between the legs when sleeping and under the ‘baby bump’
- Sit without crossing the legs and sit evenly on both buttocks
- Stand with even weight on both feet
- Keep the legs symmetrical when moving, sitting, standing, and laying down
- Avoid lifting, twisting, prolonged standing, strenuous activity, vacuum cleaning etc.
- Bend the knees and keep the legs ‘glued’ together when turning in bed and getting in/out. Silk/satin sheets can help to make it easier to turn over in bed
- Avoid straddle movements and squatting
- Move slowly and without sudden movements. Be extremely careful not to slip
- Rest – take the weight of the body off the pelvis whenever possible
- Sit down for tasks usually completed standing e.g. getting dressed, ironing, preparing food etc.
- Using a plastic bag on the car seat may make it easier to enter the car backwards and then swing the legs into the car as one unit
- If possible, shower rather than bath
- Aquanatal swimming classes – avoid breastroke as this can put more strain on the pelvis
- Obtain a pelvic support belt (ISIS Chiropractic Clinics keep these in stock) and if the pain is severe, elbow crutches will help take the weight off the pelvis and aid mobility
Plan or think ahead about every task! Ask yourself: 'How can I make it easier?', 'Do I have everything I need?', 'Do I really need to do that?'. After a while you will not even be aware of the planning and things will become second nature. Listen to your body – do not do too much of any one thing, i.e. Do not walk too far, do not sit for too long, do not exercise for too long – if it hurts, don’t do it! And remember, most people have no idea how you feel both physically and mentally. They can say and do things that might hurt or upset you without realising!
Chiropractic Treatment of SPD
The chiropractor will take a thorough medical history and do a full chiropractic and orthopaedic examination to diagnose the condition.
Chiropractic treatment may involve:
- Evaluation / treatment of the sacroiliac joints and pubic symphysis
- Work on the soft tissues (muscles / ligaments)
- Ligament release techniques
- Diaphragmatic release
- Blocking techniques (using wedge-shaped blocks placed under the pelvis to relieve the pressure on the joints)
- Activator techniques (non-manipulative techniques for the dysfunctional joints)
- Webster’s technique (to treat malpositioned babies, often associated with SPD)
- Application of ice
- Ultrasound and laser therapy
- Exercise advice
- Supply a sacroiliac (pelvic joint) stability belt
The majority of women who receive chiropractic treatment for SPD, both before or after the baby is born, will experience a positive response, particularly if the cause lies in pelvic misalignment. Chiropractic treatment aims to address the root cause of the problem instead of addressing only the symptoms. From the Chiropractic point of view, it is better for a woman with mild SPD to get treatment early on to prevent the problem from becoming more severe later or impeding the birth of your baby.
