“…In addition to the pelvic floor muscles, the abdominal muscles undergo substantial anatomical changes during pregnancy and delivery, causing rectus diastasis and a significant reduction in rectus abdominis muscle thickness 13. ) With regard to urinary incontinence in middle-aged and elderly women, Tajiri et al14 ) reported reduced TrA muscle thickness as one of the predictors of urinary incontinence. However, we could not find any study of the relationship between urinary incontinence and the thickness of the TrA muscle in postpartum subjects.…”

[Purpose] Urinary incontinence is a frequent postpartum complication. Thus, this study aimed to examine the associations of transversus abdominis muscle thicknesses at rest and during an abdominal drawing-in maneuver with urinary incontinence in females at 2 months postpartum. [Participants and Methods] The participants included 18 females at 2 months postpartum with or without urinary incontinence, and 10 nulliparous females as controls. Transversus abdominis thickness was measured at rest and during the abdominal drawing-in maneuver using diagnostic ultrasonography. The Japanese version of the International Consultation on Incontinence Questionnaire-Short Form was used to evaluate urinary incontinence. [Results] Females at 2 months postpartum were divided into groups with and without urinary incontinence according to questionnaire scores. The muscle thickness during the abdominal drawing-in maneuver contraction was significantly lower in those with urinary incontinence than in those without urinary incontinence and controls. [Conclusion] The results showed significantly reduced transversus abdominis thickness during contraction, which suggested reduced transversus abdominis strength in females with postpartum urinary incontinence. Thus, promoting synergistic contraction of the inner unit, including the transversus abdominis, in exercise therapy may be more effective for postpartum urinary incontinence.

“…However, in SUI patients, inadequate contraction of TrA during expiration leads to abdominal wall bulging [21], and the PFM is forced down, thereby decreasing urethral pressure [20]. Tajiri et al also noted the importance of TrA muscle, and reported a decrease in its thickness as the predictor of urinary incontinence [22]. the expiration, and compensate for the reduced contribution thickness change of TrA.…”

Lateral abdominal muscle thickness during breathing maneuvers in women with and without stress urinary incontinence

Introduction and hypothesis Stress urinary incontinence (SUI) patients predominantly experience involuntary leakage during respiratory functions that induce a rapid increase in intra-abdominal pressure (IAP) such as coughing and sneezing. The abdominal muscles have an important role in the forced expiration and modulation of IAP. We hypothesized that SUI patients have different thickness changes in the abdominal muscles compared to healthy individuals during breathing maneuvers. Methods This case–control study was conducted on 17 adult women with SUI and 20 continent women. Muscle thickness changes were measured by ultrasonography at the end of deep inspiration and expiration, and the expiratory phase of voluntary coughing for external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) muscles. The percent thickness changes of muscles were used and analyzed with a two-way mixed ANOVA test and post-hoc pairwise comparison at a confidence level of 95% ( p < 0.05). Results The percent thickness changes of TrA muscle were significantly lower in SUI patients at deep expiration ( p < 0.001, Cohen's d = 2.055) and coughing ( p < 0.001, Cohen's d=1.691). While, percent thickness changes for EO ( p = 0.004, Cohen's d=0.996) and IO thickness ( p < 0.001, Cohen's d=1.784) were greater at deep expiration and deep inspiration, respectively. Conclusions The percent thickness changes of abdominal muscles differed between women with and without SUI during breathing maneuvers. The present study provided information regarding the altered function of abdominal muscles during breathing maneuvers; therefore, it is important to consider the respiratory role of abdominal muscles for the rehabilitation of SUI patients.

“…In our previous study, the cutoff value for the thickness of the TA during maximal co-contraction of both the TA and PFM was 5.00 mm. This result indicates that the detectability of the risk of urinary incontinence is high and that quantitative assessment of the risk of UI is possible through measurement of the thickness of the TA during maximal co-contraction of both the TA and PFM 10 , 11 ) . In the present study, when the SUI disappeared, the thickness of the TA was greater than the cutoff value.…”

[Purpose] The purpose of this study was to devise a new urinary incontinence exercise using co-contraction of both the transverse abdominal muscle (TA) and pelvic floor muscle (PFM) and examine the intervention effect in middle-aged women with stress urinary incontinence (SUI). [Subjects] The subjects were fifteen women with SUI who were divided into two groups: the TA and PFM co-contraction exercise group (n=9) and the control group (n=6). [Methods] Participants in the exercise group performed TA and PFM co-contraction exercise. The thickness of the TA was measured before and after 8 weeks of exercise using ultrasound. The thickness of the TA was measured under 4 conditions: (1) at rest, (2) maximal contraction of the TA, (3) maximal contraction of the PFM, and (4) maximal co-contraction of both the TA and PFM. [Results] There were no significant differences among the results of the control group. In the exercise group, the cure rate of SUI was 88.9% after the intervention. There were significant differences in the thickness of the TA during maximal co-contraction of both the TA and PFM after the intervention. [Conclusion] The TA and PFM co-contraction exercise intervention increases the thickness of the TA and may be recommended to improve SUI in middle-aged women.
