Impact of Different Body Positions on Bioelectrical Activity of the Pelvic Floor Muscles in Nulliparous Continent Women

We examined pelvic floor muscles (PFM) activity (%MVC) in twenty nulliparous women by body position during exercise as well as the activation of abdominal muscles and the gluteus maximus during voluntary contractions of the PFMs. Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Activation of transversus abdominis, rectus abdominis, and gluteus maximus during voluntary PFM contractions was also assessed. Significant differences in mean normalized amplitudes of baseline PFM activity were revealed between standing and lying (P<0.00024) and lying and ball-sitting positions (P<0.0053). Average peak, average time before peak, and average time after peak did not differ significantly during the voluntary contractions of the PFMs. Baseline PFM activity seemed to depend on the body position and was the highest in standing. Pelvic floor muscles activity during voluntary contractions did not differ by position in continent women. Statistically significant differences between the supine lying and sitting positions were only observed during a sustained 60-second contraction of the PFMs.

Abstract Background: To determine the effects of the pelvic floor muscle training (PFM-T) in combination with transverse abdominal muscle (TRA) activation (cPFM-T) in female urinary incontinence.Methods: We enrolled nulliparous women in supine (SUG) (n = 22), sitting (SIG) (n = 19) and control (COG) (n = 14) groups. We performed the 8-week cPFM-T programme. We examined the effect of training on the parameters with the Kruskal–Wallis test, and the pairwise comparisons with the Mann-Whitney U-test and the Wilcoxon-rank test with the Bonferroni correction.Results: Before training, 15 participants reported occasional urinary leakage. After cPFM-T seven participants reported that urinary leakage had disappeared. Maximal isometric contraction of the pelvic floor muscles (PFM) until fatigue improved significantly in the SUG (p < 0.001) and SIG (p = 0.015) and not significantly in the COG (p = 0.499). Holding time increased in the SUG (p = 0.972) and the SIG (p = 0.717), and decreased in the COG (p = 0.132). The dynamic endurance of the PFM improved significantly in the SUG (p < 0.001), but not in the SIG (p = 0.798) and the COG (p = 0.153). The number of maximal fast contractions within 1 minute increased in both the SUG (p < 0.001) and the SIG (p=0.813) and decreased in the COG (p = 0.257). Relaxation improved significantly in the SIG (p = 0.011). TRA thickness increased in both training groups.Conclusions: Slow-twitch fibres of the PFM can be trained effectively with PFM-T in both the body positions.Trial registration: This study was registered in the Hungarian National Healthcare Service Center: 019234/2014/OTIG Registered 07 April 2014 modification: 096623-002/2015/OTIG Registered 11 November 2015 https://www.aeek.huThe study was retrospectively registered in ClincalTrials.gov NCT04577872 Registered 22 September 2020. https:// https://clinicaltrials.gov

Postural Support

The pelvic floor muscles form the base of the abdominal cylinder and work in synergy with other muscles around the cylinder - the abdominal muscles and the diaphragm. Activity in each muscle group affects the others. Coordinated recruitment of these muscle groups is necessary for generation and maintenance of intra-abdominal pressure, postural support of the trunk, and during functional tasks such as lifting, coughing and nose blowing. Coordinated release of these groups is required for micturition, while defaecation may need activity in some muscles and release in others. Vaginismus and vulvodynia both have a component of over activity of the pelvic floor muscles which impairs normal function, though this over activity may only occur at the time of attempted penetration. Some of the physiological factors that contribute to this overactivity come from outside the pelvic floor muscle complex itself and can be ameliorated by understanding and management of these muscle synergies. An EMG study of muscle activity of the abdominal and pelvic floor muscles during a simulated body posturing for female sexual arousal will help to explain how the pelvic floor muscle over activity in vaginismus arises. Treatment programmes that have been used to successfully address these problems will be explained.

Objectives. Evaluation of resting and functional bioelectrical activity of the pelvic floor muscles (PFM) and the synergistic muscles, depending on the orientation of the pelvis, in anterior (P1) and posterior (P2) pelvic tilt.Design. Preliminary, prospective observational study.Setting. Department and Clinic of Urology, University Hospital in Wroclaw, Poland.Participants. Thirty-two menopausal and postmenopausal women with stress urinary incontinence were recruited. Based on inclusion and exclusion criteria, sixteen women aged 55 to 70 years were enrolled in the study.Primary Outcome Measures. Evaluation of resting and functional bioelectrical activity of the pelvic floor muscles by electromyography (sEMG) and vaginal probe.Secondary Outcome Measures. Evaluation of activity of the synergistic muscles by sEMG and surface electrodes.Results. No significant differences between orientations P1 and P2 were found in functional and resting sEMG activity of the PFM. During resting and functional PFM activity, higher electrical activity in P2 than in P1 has been recorded in some of the synergistic muscles.Conclusions. This preliminary study does not provide initial evidence that pelvic tilt influences PFM activation. Although different activity of synergistic muscles occurs in various orientations of the pelvic tilt, it does not have to affect the sEMG activity of the PFM.

Objective.The objective of this study was to compare the role of the pelvic floor muscles between nulliparous and multiparous women in the third trimester of pregnancy, by analyzing the relationship between electrical activity (surface electromyography—EMG), vaginal palpation (modified Oxford scale), and perineal distensibility (Epi-no).Methods.This was an observational cross-sectional study on a sample of 60 healthy pregnant women with no cervical dilation, single fetus, gestational age between 35 and 40 weeks, and maternal age ranging from 15 to 40 years. The methods used were bidigital palpation (modified Oxford scale, graded 0–5), surface EMG (electrical activity during maximal voluntary contraction), and perineal distensibility (Epi-no device). The Pearson correlation coefficient (r) was used to analyze the Epi-no values and the surface EMG findings. The Kruskal-Wallis test was used to compare the median values from surface EMG and Epi-no, using the modified Oxford scale scores.Results.Among the 60 patients included in this study, 30 were nulliparous and 30 multiparous. The average maternal age and gestational age were 26.06 (±5.58) and 36.56 (±1.23), respectively. It was observed that nulliparous women had both higher perineal muscle strength (2.53 ± 0.57versus2.06 ± 0.64;P = 0.005) and higher electrical activity (45.35 ± 12.24 μV versus35.79 ± 11.66 μV;P = 0.003), while among the multiparous women, distensibility was higher (19.39 ± 1.92versus18.05 ± 2.14;P = 0.013). We observed that there was no correlation between perineal distensibility and electrical activity during maximal voluntary contraction (r = -0.193;P = 0.140). However, we found a positive relationship between vaginal palpation and surface electromyography (P = 0.008), but none between Epi-no values (P = 0.785).Conclusion.The electrical activity and muscle strength of the pelvic floor muscles of the multiparous women were damaged, in relation to the nulliparous women, while the perineal distensibility was lower in the latter group. There was a positive relationship between surface EMG and the modified Oxford scale.
