Comparison of sacroiliac joint movement between primigravida and non pregnant women
Abstract:
The aim of this study was to compare the change of sacroiliac joint
displacement between primigravida women in third trimester and healthy female
subjects by detecting posterior superior iliac spine on the modified Gillet test. Thai
pregnant women aged between 20 and 35 years at 28-30 weeks gestation and Thai
healthy non pregnant women at the same age range participated in this study. Each
group consisted of 30 subjects. The displacement of sacroiliac joint was recorded by
digital camera from erect standing position to 90º flexion of hip and knee in each side
of both groups.
The results showed that sacroiliac joint displacements of the primigravida
women were significantly greater than those of the non pregnant women for both sides
(p<0.01). The sacroiliac joint displacements of pregnant women for left and right sides
were 3.69±1.49 mm and 3.95±1.72 mm respectively. The sacroiliac joint
displacements of non pregnant women for left and right were 2.16±1.01 mm and
2.08±1.19 mm respectively. Moreover, there was no significant difference in either
left or right sacroiliac joint displacement between pregnant women with and without
lumbopelvic pain.
In conclusion, this study provides information on the sacroiliac joint
displacements of primigravida women in third trimester and non pregnant women at
the same age range. This study indicates that primigravida women in the third
trimester have an almost two times greater sacroiliac displacement than the non
pregnant women. This can lead to pain and sacroiliac joint dysfunction after delivery.
Therefore, physical therapists should recommend lumbopelvic stabilization exercises
for post partum period in order to prevent a further dysfunction. In addition, this study
also provides quantitative measurement of sacroiliac joint displacement that can be
applied in clinics.
