Impact of different body positions on bioelectrical activity of the pelvic floor muscles in iparous continent women.

Bottom Line: 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).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
We examined pelvic floor muscles (PFM) activity (%MVC) in twenty iparous 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.

Mentions: The analysis of the baseline test results revealed statistically significant differences between supine lying, standing, and sitting. The mean resting activity of PFMs was the lowest in supine lying (Figure 2) and was significantly different compared to standing (P = 0.00024) and sitting (P = 0.0053) positions. No statistically significant differences were seen between standing and sitting positions (P = 0.4).
