: Postpartum women frequently experience nonspecific low back pain (NSLBP), yet the impact of delivery mode on the function of local core muscles, particularly the transversus abdominis (TrA) and lumbar multifidus (LM), is not well understood, limiting the development of targeted rehabilitation strategies. To compare NSLBP intensity and TrA and LM strength in women who underwent cesarean delivery (CD) or vaginal delivery (VD), and to examine the associations between pain intensity and muscle strength. : An analytical cross-sectional study was conducted on 36 women divided into two groups: 18 who underwent CD (Group A) and 18 who underwent VD (Group B). NSLBP intensity was assessed using the visual analogue scale, while TrA and LM strength were measured via a pressure biofeedback unit. : The two groups showed non-significant differences in age ( = 0.342), BMI ( = 0.429), or parity ( = 0.894), confirming comparable baseline characteristics. NSLBP intensity was significantly higher in the CD group ( = 0.000), and they exhibited weaker TrA ( = 0.009) strength than the VD group; however, there was a non-significant difference in LM strength ( = 0.602). The Spearman correlation analysis revealed non-significant associations between NSLBP intensity and TrA and LM strength in the CD group ( = 0.702, 0.129, respectively) and in the VD group ( = 0.149, 0.877, respectively). : Women undergoing CD experienced higher NSLBP intensities and weaker TrA strength than those undergoing VD, while LM strength remained similar between groups. However, NSLBP intensity showed non-significant associations with TrA or LM strength in either group, suggesting that other biomechanical or neuromuscular factors may contribute to the increased post-CD NSLBP. These findings highlight the need for targeted rehabilitation strategies beyond core muscle strengthening alone.
产后女性经常经历非特异性下腰痛（NSLBP），然而分娩方式对局部核心肌肉功能的影响，尤其是腹横肌（TrA）和腰多裂肌（LM），尚未得到充分理解，这限制了针对性康复策略的发展。为了比较剖宫产（CD）或阴道分娩（VD）女性的NSLBP强度以及TrA和LM的力量，并研究疼痛强度与肌肉力量之间的关联。：对36名女性进行了一项分析性横断面研究，分为两组：18名接受剖宫产的女性（A组）和18名接受阴道分娩的女性（B组）。使用视觉模拟量表评估NSLBP强度，而通过压力生物反馈装置测量TrA和LM的力量。：两组在年龄（ = 0.342）、体重指数（ = 0.429）或产次（ = 0.894）方面无显著差异，证实了基线特征具有可比性。CD组的NSLBP强度显著更高（ = 0.000），并且与VD组相比，其TrA力量较弱（ = 0.009）；然而，LM力量无显著差异（ = 0.602）。Spearman相关性分析显示，CD组中NSLBP强度与TrA和LM力量之间无显著关联（分别为 = 0.702，0.129），VD组中也是如此（分别为 = 0.149，0.877）。：与接受VD的女性相比，接受CD的女性经历更高的NSLBP强度和较弱的TrA力量，而两组之间的LM力量保持相似。然而，在任何一组中，NSLBP强度与TrA或LM力量均无显著关联，这表明其他生物力学或神经肌肉因素可能导致CD后NSLBP增加。这些发现凸显了除单纯强化核心肌肉之外的针对性康复策略的必要性。
