Abstract:

nd: Understanding differences in mechanics between pregnant and non-pregnant females are a first step toward identifying potential pathological mechanisms. Objectives: The objective was to investigate systematic changes in the range of motion of pelvis in all three trimesters of pregnancy and its correlation to BMI. Materials and Methods: One hundred and seventy-four primigravida pregnant females with age group of 20–30 years completed testing on three occasions (first trimester, second trimester, and third trimester) using goniometer. The patient was made comfortable and her height, weight was measured to calculate the BMI. Later with the help of goniometer range of motion of pelvis (hip and lumbar) was measured. Results: In this study, significant correlation was seen for anterior pelvic tilt, posterior pelvic tilt, and backward rotation for the first and third trimester. Very significant correlation was seen for anterior pelvic tilt, posterior pelvic tilt, lateral pelvic tilt, forward rotation, backward rotation in the second trimester, and for backward rotation in the third trimester. Extremely significant correlation was seen for posterior pelvic tilt in the first trimester, for anterior and posterior pelvic tilt in the second trimester, for posterior pelvic tilt in the third trimester. Conclusion: In this study, significant correlation was seen for the first and third trimester. Very significant correlation was seen for the second trimester and for third trimester. Extremely significant correlation was seen in the first trimester, second trimester, and third trimesters.
