Impact of lumbopelvic pain on the postural balance during sit-to-stand activity in pregnant women: a cross-sectional study

Abstract

Introduction: The emergence of painful pathologies during gestation, such as lumbopelvic pain (LPP), can influence in the achievement of functional activities, such as sit-to-stand, throughout the gestational period. Objective: To compare the variables of static and dynamic postural balance (sit-to-stand activity) among pregnant women with and whitout lumbopelvic pain and the outcome variables between the gestational trimesters. Method: A total of 100 pregnant women participated in this study allocated as follows: 51 in the LPP group and 49 in the group without LPP. All participants were subjected to an evaluation protocol: filling an identification form, Analogic Visual Scale (AVS) and Oswestry Disability Index (ODI). Evaluation of postural balance was subsequently performed using the Balance Master System®. Results: 64.7% of women during the third trimester of pregnancy reported LPP. No statistically significant differences were found between LBP presence or absence in postural balance variables (p>0.05). However, gestational age influenced the VFEC variable (p=0.001). Conclusion: Women during the third gestational trimester presented complaints of lumbopelvic pain. However, the data acquired suggest that women with LPP do not have alterations in postural balance during sit-to-stand movement when compared to pregnant women without pain.
