Does abdominal diastasis influence lumbar pain during gestation?

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

BACKGROUND AND OBJECTIVES:

To evaluate and compare the presence and size of recti abdominis diastasis in the second and third gestational trimester and to correlate them to lumbar pain incidence and intensity.

METHODS:

This is a cross-sectional observational study with 128 pregnant women divided in two groups: 53 pregnant women in the second gestational trimester and 75 pregnant women in the third gestational trimester. Lumbar pain was evaluated with Roland Morris questionnaire and Pain Visual Analog Scale. Recti abdominis diastasis was measured with a caliper rule. Data were analyzed according to Spearman correlation and Mann-Whitney U test.

RESULTS:

Comparison between groups has shown that pregnant women in the third gestational trimester had more recti abdominis diastasis, more reports of severe lumbar pain by the visual analog scale (p=0.0017) and further impact on daily life activities (p=0.0012). There has been positive correlation between recti abdominis diastasis size and scores obtained by Roland Morris questionnaire and visual analog scale.

CONCLUSION:

Recti abdominis diastasis size, pain intensity and incapacity determined by low back pain were more severe in pregnant women in the third gestational trimester.
