Effectiveness of Lumbopelvic Stabilization Exercises for Pregnancy-related Low Back Pain

Texas Woman's University

Overview

The purpose of this study is to examine the effectiveness of lumbopelvic stabilization exercises on women who have undergone Caesarian sections on: 1) disability using the Modified Oswestry Low Back Disability Index (OSW), 2) pain according to the Numeric Pain Rating Scale (NPRS), 3) percent change of muscle thickness of the deep abdominals using ultrasound imaging, and 4) perceived improvement using the Global Rating of Change (GROC).

Pregnancy-related low back pain is a very complex problem. Decreased strength and endurance in the trunk and hip muscles have been shown in those with pregnancy-related low back pain. Lumbopelvic stabilization exercises have been shown to decrease pain and disability in those with low back pain. However, there have been very few studies with post-partum women, specifically those who have undergone Caesarian section births. The purpose of this study is to examine the effectiveness of lumbopelvic stabilization exercises on women who have undergone Caesarian sections on: 1) disability using the Modified Oswestry Low Back Disability Index (OSW), 2) pain according to the Numeric Pain Rating Scale (NPRS), 3) percent change of muscle thickness of the deep abdominals using ultrasound imaging, and 4) perceived improvement using the Global Rating of Change (GROC).
