Abstract

Background: Morphological changes in the abdominal wall muscle in diastasis recti abdominis (DRA) patients with low back pain (LBP) symptoms and whether there is a wider interrectus distance (IRD) remain unclear.

Objective: The aim of this study was to determine the correlation between DRA severity and LBP and the morphological differences in abdominal wall muscles between patients who presented with symptoms of LBP and those who were asymptomatic.

Methods: A total of 57 postpartum DRA patients were enrolled, including 21 without LBP, 36 with LBP, and 30 healthy nulliparous women. The numerical rating scale (NRS) was used to evaluate the degree of LBP. The IRD and muscle thickness of the abdominal muscles were measured via an ultrasonography device at the end of a natural breathing cycle.

Results: The abdominal muscles of the rectus abdominis (RA), external oblique muscle (EO), and transversus abdominis (TrA) in the DRA patients were significantly thinner than those in the control group (p< 0.05), whereas the difference in the internal oblique muscle (IO) was not significant (p> 0.05). There were no statistically significant differences in abdominal muscle thickness or the IRD regardless of whether the patients with DRA had LBP symptoms, with similar findings between the NRS score and DRA severity (P> 0.05).

Conclusion: In DRA patients within one year postpartum, no significant difference was found in the severity of DRA or abdominal muscles, regardless of whether they were complicated by LBP symptoms. Shortening the IRD alone may not be beneficial for improving LBP symptoms in DRA patients. The relationship between DRA and LBP and the role of the abdominal muscles in postpartum LBP should be interpreted with caution.

自我报告的腰背痛与腹壁肌肉形态变化之间的相关性。
背景:有腰背痛(LBP)症状的腹肌直肠膨出(DRA)患者的腹壁肌肉形态变化以及直肌间距离(IRD)是否更宽仍不清楚:本研究旨在确定 DRA 严重程度与腰背痛之间的相关性,以及出现腰背痛症状的患者与无症状患者之间腹壁肌肉的形态差异:方法:共招募了 57 名产后 DRA 患者,包括 21 名无 LBP 患者、36 名有 LBP 患者和 30 名健康的无产褥期妇女。采用数字评分量表(NRS)评估枸杞痛的程度。在自然呼吸周期结束时,通过超声波设备测量腹部肌肉的内径和肌肉厚度:结果:DRA 患者的腹直肌(RA)、腹外斜肌(EO)和腹横肌(TRA)明显比对照组薄(P< 0.05),而腹内斜肌(IO)差异不显著(P> 0.05)。无论 DRA 患者是否有 LBP 症状,腹肌厚度或 IRD 均无明显统计学差异,NRS 评分与 DRA 严重程度的结果相似(P> 0.05):结论:在产后一年内的 DRA 患者中,无论是否合并有枸杞痛症状,DRA 或腹部肌肉的严重程度均无明显差异。单纯缩短 IRD 可能无益于改善 DRA 患者的 LBP 症状。在解释 DRA 与枸杞痛之间的关系以及腹部肌肉在产后枸杞痛中的作用时应谨慎。

期刊介绍: The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty. In each issue clinicians can find information which they can use in their patient setting the very next day.
