Trial for the Treatment of Pelvic and Back Pain in Pregnancy

Randomised Controlled Trial for the Treatment of Pelvic Girdle Pain in Pregnancy

• Status: Unknown
• Phase: N/A
• Study type: Interventional

Summary

The investigators aim to conduct a prospective open label randomized controlled trial to test the hypothesis that following initial assessment by a physiotherapist, group care exercise class is as effective in reducing pain as individual physiotherapy care.

Detailed description

Back pain is reported to affect at least 75% of women at some stage during their pregnancy. In the United States one review found that approximately a third of women find back pain in pregnancy a severe problem. It has been reported that 20% of all pregnant women suffer from the condition to such an extent that they require medical help. Six years after pregnancy, problems remain in about 7% of women with PGP, causing severe disability and reducing ability to work. The increase in back pain in pregnancy occurs most likely as a result of the natural underlying posture deviations been accentuated in pregnancy. Anterior displacement of the sacrum, posterior displacement of the trunk and a significant increase in the anterior tilt of the pelvis results in exaggerated lordosis of the lower back. Stretching, weakness, and separation of abdominal muscles further impede neutral posture and place even more strain on paraspinal muscles. Joint laxity in the anterior and posterior longitudinal ligaments of the lumbar spine puts strain on the lumbar spine and there is widening and increased mobility of the sacroiliac joints and pubic symphysis to facilitate the baby's passage through the birth canal. A significant cause of back pain in pregnancy appears to result from pelvic girdle pain (PGP). Back pain in pregnancy is more common in women with pre-existing back pain, back pain in a previous pregnancy, advanced maternal age and multiparity. Despite the high incidence of back pain in pregnancy (75% of women attending antenatal clinics at Cork University Maternity Hospital) only a fraction of women (25% in the same audit) report back pain to their health care providers presumably due to their perception that there are minimal interventions for the safe treatment of back pain in pregnancy. Similar results have been shown in other studies. A Cochrane review on interventions for preventing and treating pelvic and back pain in pregnancy republished in October 2008 found no studies dealing specifically with prevention of back or pelvic pain in pregnancy. They included eight studies (1305 participants) that examined the effects of adding various pregnancy-specific exercises, physiotherapy, acupuncture and pillows compared with usual prenatal care. They concluded that all but one study had moderate to high potential for bias. Adding pregnancy specific exercises, physiotherapy or acupuncture to usual prenatal care appears to relieve back or pelvic pain more than usual prenatal care alone, although the effects appear small. Recent trials investigating the effect of acupuncture on PGP concluded that acupuncture and stabilising exercises constitute efficient complements to standard treatment for the management of PGP in pregnancy but acupuncture alone has no significant effect on pain or on the degree of sick leave compared with non penetrating sham acupuncture. The pain of PGP is experienced between the posterior iliac crest and the gluteal fold, particularly in the vicinity of the sacroiliac joints. The endurance capacity for standing, walking and sitting is diminished. Diagnosis can only be reached after exclusion of lumbar causes and this diagnosis should be based on a medical history, a physical standardised examination with specific clinical tests that reproduce pain in the pelvic girdle. The European guidelines state that available evidence is insufficient to recommend any particular treatment modality.

Conditions

• Pelvic Girdle Pain
• Symphysio Pubic Dysfunction

Interventions

Type	Name	Description
PROCEDURE	Individual care	The first treatment group (individual care group) will involve 3 sessions held weekly. Each session will last approximately 45 minutes.
PROCEDURE	group care	The second treatment group (group care group) will be assigned to weekly group exercise classes, focusing on core stability and strengthening exercises. Classes will last one hour and will be conducted for 4 weeks. In both treatment groups pain scores will be followed up for 1 week post last treatment.
