腹肌收缩对盆底肌收缩能力的影响研究

Effect of abdominal muscle contraction on pelvic floor muscle contraction ability

目的 探讨腹肌收缩对盆底肌收缩能力的影响。方法 选取2023年2~9月在河南省人民医院进行盆底功能检查的171例产妇,采用Phenix U2测量阴道静息状态时的压力及盆底肌、腹肌不同收缩模式下的阴道动态压力,将盆腹肌同时收缩时阴道动态压力峰值的变化值(△3)与单独收缩腹肌及单独收缩盆底肌变化值之和(△1+△2)进行比较;测量盆底肌电位,比较单独收缩盆底肌及盆腹肌同时收缩时盆底肌电位的峰值。结果 静息状态下阴道压力、单独收缩腹肌、单独收缩盆底肌、盆腹肌同时收缩时阴道动态压力峰值平均值分别为52.00(8.00)mmHg、57.00(8.00)mmHg、60.00(10.00)mmHg、67.00(14.00)mmHg,△3大于△1+△2之和,二者之间差异有统计学意义(Z=-10.104,P<0.01);单独收缩盆底肌、盆腹肌同时收缩时盆底肌电位的峰值分别为14.00(6.00)μV、21.00(10.00)μV,二者差异有统计学意义(Z=-8.947,P<0.01)。结论 盆底肌训练时腹肌同时收缩可增加阴道动态压力峰值、提高盆底肌肌电位,收缩腹肌更有利于盆底肌的收缩,因此产后盆底肌训练时无需放松腹肌。

Objective To observe the effect of abdominal muscle contraction on pelvic floor muscle contraction ability.Methods From February 2023 to September 2023,a total of 171 postpartum women who underwent pelvic floor function examination in Henan Provincial People′s hospital were selected.Phenix U2 was used to measure the vaginal pressure at rest and peak dynamic pressure under different muscle contraction modes.The increase in vaginal dynamic pressure(△3)when pelvic and abdominal muscles were contracted at the same time was compared with the sum of the increase in the pressure when abdominal muscles and pelvic floor muscles were contracted respectively(△1+△2).Measure the pelvic floor muscle potential,and compare the peak potential when the pelvic and abdominal muscles were contracted at the same time with that when the pelvic floor muscles were contracted alone.Results The pressure at rest,peak vaginal dynamic pressure during contraction of abdominal muscles alone,contraction of pelvic floor muscles alone and contraction of pelvic and abdominal muscles at the same time were 52.00(8.00)mmHg,57.00(8.00)mmHg,60.00(10.00)mmHg and 67.00(14.00)mmHg respectively.△3 was greater than△1+△2(Z=-10.104,P<0.01).The peak pelvic floor muscle potential was 14.00(6.00)μV and 21.00(10.00)μV when the pelvic floor muscles were contracted alone and the pelvic and abdominal muscles were contracted at the same time,and the difference between them was statistically significant(Z=-8.947,P<0.01).Conclusion The simultaneous contraction of abdominal muscles during pelvic floor muscle training can increase vaginal pressure and improve pelvic floor muscle potential.Contraction of abdominal muscles is more conducive to the contraction of pelvic floor muscles,so it is not necessary to relax abdominal muscles during pelvic floor muscle training.
