Background: Prospective studies have described evidence about the risk of developing pregnancy-related pelvic girdle pain (PPGP) such as, parity, previous history of low back and pelvic girdle pain. No previous studies have prospectively associated PPGP with postural control.
Aim: This study aimed to identify postural control predictors of PPGP during pregnancy.
Methods: Forty-six pregnant women were surveyed throughout their pregnancy for the presence of PPGP. At baseline, participants were evaluated for muscle latencies, mediolateral centre-of-pressure (COP) displacement and velocity during single-leg lift performed with eyes open and closed. PPGP was considered if they presented with one positive clinical assessment as well as pain within the pelvic area.
Results: Eighteen (45%) of the participants developed PPGP. This group presented with PPGP around a mean 29th week (SD = 5.7), with mean pelvic pain intensity of 4 mm VAS (SD = 2) on a (0-10 cm VAS) and mean PPGP questionnaire score of 21.5 points (SD = 10.6) out of a possible 100 points with 0 indicating no functional disability. The two factors that were significantly associated with PPGP were the right and left biceps femoris (BF) muscle. For every 50 ms of difference of BF muscles latency between eyes open and closed, the risk of PPGP increases by 20% (right BF) and 30% (left BF) to develop PPGP.
Conclusion(s): This study shows that BF muscle delay during single-leg lift presented at baseline was a significant predictor for the development of PPGP in late pregnancy.

Background And Aims: Pregnancy-related pelvic girdle pain (PPGP) is estimated to affect between 20% and 70% of pregnant women with 10% experiencing it for more than 3 months postpartum. Women may also experience depression during this period. Understanding the prevalence of depression in women with PPGP is important to inform clinical management.

Introduction: The influence of pregnancy-related pelvic girdle pain (PPGP) on lumbopelvic muscles has not been comprehensively examined in postpartum individuals. Previous research also presented self-reported activity limitations without objective measures.
Methods: Thirty postpartum individuals with PPGP (PPGP group) and 30 age-, parity-, and postpartum duration-matched asymptomatic individuals (healthy group) were recruited.

() is a gene encoding an enzyme related to the last step of juvenile hormone biosynthesis. cDNA has a total length of 1695 bp and an open reading frame (ORF) length of 1482 bp, encoding 493 amino acids. Sequence analysis showed that its amino acid sequence has a PPGP hinge, an FGCG structural domain, and other structural domains specific to the P450 family of enzymes.

Objectives: Investigate effects of integrated training for pelvic floor muscles (PFM) with and without transabdominal ultrasonography (TAUS) imaging-guided biofeedback in postpartum women with pregnancy-related pelvic girdle pain (PPGP).
Design: Three-arm, single-blinded randomized controlled trial SETTING: University laboratory PARTICIPANTS: Fifty-three postpartum women with PPGP randomized into stabilization exercise with TAUS-guided biofeedback (BIO+EXE), exercise (EXE), and control (CON) groups.
Interventions: The BIO+EXE and EXE groups underwent an 8-week exercise program, with the BIO+EXE group receiving additional TAUS-guided biofeedback for PFM training during the first 4 weeks.

Introduction: During pregnancy, many changes in the musculoskeletal system and pregnancy-related disorders affect posture and postural stability. Pregnancy-related pelvic girdle pain (PPGP) is a common disorder in pregnancy; the cause remains unknown. The purpose of the present study was to determine if PPGP affects static postural stability and its relation to the stage of pregnancy.
