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.

BACKGROUND AND OBJECTIVES: The various gestational adaptations may lead to changes in the gait pattern. Also, the lumbopelvic pain in this period can impact the gait dynamics. The objective of this study was to compare gait variables between pregnant women with and without lumbopelvic pain, according to the gestational trimesters, and to compare the outcome variables between the second and third gestational trimesters. METHODS: Analytical and cross-sectional study with 277 pregnant women. They were divided into two groups, considering the gestational trimester as a grouping factor. Subsequently, the two groups were subdivided considering the absence or presence of lumbopelvic pain. All participants were submitted to the evaluation protocol: identification form, visual analog scale, and gait assessment using the Balance Master System®. RESULTS: The chronological age averages of the second and third-trimester groups were, respectively, 29.9±4.6 and 29.7±3.7 years. When comparing gait variables between pregnant women with and without lumbopelvic pain, a statistically significant difference was observed only for the gait velocity (p=0.04) in the third-trimester group. CONCLUSION: It is suggested that women in the third trimester with complaints of lumbopelvic pain have reduced gait velocity when compared to those without pain.
