Stress urinary incontinence (SUI) primarily results from the weakness of pelvic floor muscles, working synergistically with the abdominal muscles. The current study aimed to compare thickness and contractile function of lateral abdominal muscles in women with and without SUI.
Thirty-nine women with SUI (SUI group; age: 38.87 ± 8.96 years, body mass index (BMI): 24.03 (5.94) kg/m) and 42 healthy women (control group; age: 36.21 ± 11.46 years, BMI: 23.90 (5.85) kg/m) were included. Transverse abdominis (TrA) and internal oblique (IO) muscle thickness at rest and during abdominal drawing-in maneuver (ADIM) were measured with ultrasound imaging in B-mode using a Logiq S7/Expert device and a 9-11 MHz linear transducer. Percentage change in thickness and contractile function of these muscles were also calculated.
No significant differences in the thickness of TrA and IO muscles at rest and during ADIM between the groups were found (p > 0.05). The percent change in thickness and contractile function of both right and left side TrA muscles and the right side IO muscle were lower in SUI group than control group (p < 0.05). The percentage change in thickness and the contractile function of the left side IO muscle did not change (p > 0.05).
Women with SUI had a smaller percentage change in thickness and contractile function of TrA and IO muscle than women without SUI. However, there was no difference in the morphological features of these muscles between the groups. Considering the lateral abdominal muscle, training may be important for management of SUI.
压力性尿失禁（SUI）主要是由于盆底肌肉的虚弱，与腹部肌肉协同作用。本研究旨在比较有和无 SUI 的女性侧腹肌的厚度和收缩功能。
纳入 39 名 SUI 女性（SUI 组；年龄：38.87±8.96 岁，体重指数（BMI）：24.03（5.94）kg/m）和 42 名健康女性（对照组；年龄：36.21±11.46 岁，BMI：23.90（5.85）kg/m）。使用 Logiq S7/Expert 设备和 9-11MHz 线性换能器的 B 模式，通过超声成像测量横腹肌（TrA）和内斜肌（IO）在休息和腹部内收运动（ADIM）时的厚度。还计算了这些肌肉的厚度和收缩功能的百分比变化。
两组间 TrA 和 IO 肌肉在休息和 ADIM 时的厚度无显著差异（p>0.05）。与对照组相比，SUI 组右侧和左侧 TrA 肌肉以及右侧 IO 肌肉的厚度和收缩功能百分比变化较低（p<0.05）。左侧 IO 肌肉的厚度百分比变化和收缩功能没有改变（p>0.05）。
与无 SUI 的女性相比，SUI 女性的 TrA 和 IO 肌肉厚度和收缩功能的百分比变化较小。然而，两组间这些肌肉的形态特征没有差异。考虑到侧腹肌，训练对于 SUI 的管理可能很重要。
