Pelvic pain during pregnancy is associated with asymmetric laxity of the sacroiliac joints

Abstract

Increased SIJ laxity is not associated with PRPP. In fact, pregnant women with moderate or severe pelvic pain have the same laxity in the SIJs as pregnant women with no or mild pain. However, a clear relation between asymmetric laxity of the SIJs and PRPP is found.

Pain, Disability, and Diagnostic Accuracy of Clinical Instability and Endurance Tests in Subjects With Lumbar Spondylolisthesis

“…It is a valid and reliable tool to assess the ability to transfer load between the spine and the legs via the pelvis. 42,50,51 Several studies demonstrated its usefulness as a screen for core muscles. 52 -56 Other studies analyzed this test in carefully selected subgroups of subjects, such as patients with sacroiliac joint pain 57 or with posterior pelvic pain since pregnancy.…”

Innominate movement patterns, rotation trends and range of motion in individuals with low back pain of sacroiliac joint origin

“…Putatively, the unilateral innominate movement pattern is indicative of a particular model of physiological restriction, which derives from an asymmetric stiffness between the pelvic joints in SIJ-positive individuals. 2.1 ± 1.6 1.9 ± 1.8 1.7 ± 1.5 1.5 ± 1.2 Sagittal innominate range of motion (degrees) (Mean ± SD) Right 2.8 ± 2.6 3.2 ± 2.2 4.5 ± 4.6 2.5 ± 2.6 Left 3.5 ± 2.1 3.7 ± 2.3 3.6 ± 3.0 2.9 ± 2.0 Asymmetric stiffness has been demonstrated previously in patients experiencing pregnancy related pelvic girdle pain (Damen et al, 2001(Damen et al, , 2002. Moreover, Bussey and Milosavljevic (2013), also found a similar unilateral pattern in AS participants.…”

Low back pain associated with pregnancy: a review of literature

“…Disability as the result of pain is often measured using the Quebec Back Pain Disability Scale. While this scale is used primarily to measure disability from nondescript low back pain not related to pregnancy, it can be adapted to use for pregnancy-related pain [21][22][23]. Several studies have attempted to develop a system to evaluate the extent and effect of pain specifically during and after pregnancy.…”
