Abstract
The main aim of our research was to objectify the relationship between the presence of LBP, the training level of the postural muscles and the degree of the pelvic inclination of women in the third trimester of pregnancy. The relationship between pelvic inclination and LBP occurrence is compared within the context of two groups - reasonable physically active as compared to physically inactive women.
The exercises were focused on the functioning of the postural systém. We measured the inclination of the pelvis (using non-invasive anthropometric measuring) and observed the presence of pain in the selected area: clinically and subjectively with the aid of a standardized LBP related survey.
We observed a statistically significant difference between the pelvic inclination of physically active and inactive women (using a t-test for non-pair values with a significance level of p = 0.01). Another significant difference was evident between the subjective pain sensation of regularly exercising and non-exercising women, which was proved by both the median and the Wilcoxon-White tests (p = 0.01).
A significant relationship between pelvic inclination and the sensation of pain classified in a survey by means of a 1-10 scale was proven by the Spearman factor of serial correlations (p = 0.01). CONCLUSIONS: Using mathematical statistical methods, our study has proved the important role of physical activity during pregnancy - its relationship to pain sensation and to the degree of pelvic inclination.
We consider these results to be very important, especially from the perspective of LBP prevention during pregnancy.
