Studies have shown that there is co-activation between abdominal and pelvic floor muscles (PFM) in physiological conditions. This study aimed to assess pelvic floor and isokinetic trunk flexors function in non-active incontinent women, and to investigate the association between the strength of these muscle groups and the severity of stress urinary incontinence (SUI).
A cross-sectional study was carried out. Twenty-five incontinent women were enrolled after one-hour pad test results and compared to twenty asymptomatic women. The severity of SUI was determined by the Pad test and Urinary Distress Inventory, Short Form (UDI-6). PFM function was assessed using the modified Oxford Scale, intra-vaginal PFM electromyography, and PFM endurance according to the PERFECT scheme. Trunk flexors strength was assessed using a Cybex Norm II dynamometer.
Incontinent women had a weaker PFM and isokinetic abdominal muscle strength compared to continent women (P<0,05). SUI severity was negatively correlated with PFM strength (r=-0,620, P=0,001), isokinetic trunk flexors strength (r=-0,605, P=0,001), and PFM endurance (r=-0,561, P=0,003) in incontinent women. A positive correlation between PFM function and isokinetic trunk flexors strength was found in incontinent women (r=0,488, P=0,013).
Non-active incontinent women had weaker pelvic floor muscles and isokinetic trunk flexors strength compared to continent ones. The positive correlation found between these two muscle groups may be explained by their synergic activity. These findings suggest that the severity of SUI could be related not only to PFM strength but also to abdominal muscle weakness. Further research is needed to recommend abdominal wall training as an alternative method to treat SUI.
研究表明，在生理状态下，腹部和盆底肌肉（PFM）存在协同激活。本研究旨在评估非活跃性尿失禁女性的盆底和等速躯干屈肌功能，并探讨这些肌肉群的力量与压力性尿失禁（SUI）严重程度之间的关系。
进行了一项横断面研究。在一小时垫试验结果后，招募了 25 名失禁女性，并与 20 名无症状女性进行了比较。SUI 的严重程度通过垫试验和尿失禁困扰量表（UDI-6）来确定。使用改良牛津量表、阴道内 PFM 肌电图和 PERFECT 方案评估 PFM 功能，根据 PERFECT 方案评估 PFM 耐力。使用 Cybex Norm II 测力计评估躯干屈肌力量。
与无症状女性相比，失禁女性的 PFM 和等速腹内肌力量较弱（P<0.05）。SUI 严重程度与 PFM 力量（r=-0.620，P=0.001）、等速躯干屈肌力量（r=-0.605，P=0.001）和 PFM 耐力（r=-0.561，P=0.003）呈负相关。在失禁女性中，PFM 功能与等速躯干屈肌力量呈正相关（r=0.488，P=0.013）。
与无症状女性相比，非活跃性尿失禁女性的盆底肌肉和等速躯干屈肌力量较弱。这两个肌肉群之间发现的正相关可能是由于它们的协同活动。这些发现表明，SUI 的严重程度不仅与 PFM 力量有关，还与腹肌无力有关。需要进一步的研究来推荐腹壁训练作为治疗 SUI 的替代方法。
