Abstract

BackgroundLocalized low back pain is a frequent complaint after spinal anesthesia for cesarean delivery (CD).ObjectivesThis study aimed to examine the pressure pain threshold (PPT) and biomechanical properties (stiffness, elasticity, relaxation time, and creep) of the L4-5 supraspinous ligament at the spinal anesthesia needle insertion site in women who had CD. These measurements were compared with those from the controls who never had pregnancy or anesthesia, and correlations between the variables were explored.MethodsA retrospective cohort study involved 44 women, divided into two groups. Group A: 22 women experienced spinal anesthesia for CD, and Group B: 22 women represented the controls. L4-5 supraspinous ligament's PPT was measured using pressure algometry, and its biomechanical properties were assessed with the MyotonPRO device.ResultsSignificant differences were found in PPT between the two groups (P = 0.0001), but non-significant differences were observed in stiffness, elasticity, relaxation time, or creep (P = 0.318, 0.344, 0.241, and 0.227, respectively). There were also non-significant correlations between PPT and biomechanical properties.ConclusionWomen who experienced spinal anesthesia for CD showed increased tenderness and lower PPT at the L4-5 site, 6-12 weeks postpartum, with minor changes in supraspinous ligament biomechanics. The relationship between PPT and these properties was negligible.

腰麻剖宫产后压力痛阈与腰4-5棘上韧带生物力学的相关性研究。
背景:局部腰痛是剖宫产(CD)脊柱麻醉后常见的主诉。目的本研究旨在检测CD患者腰麻针插入部位L4-5棘上韧带的压痛阈值(PPT)和生物力学特性(刚度、弹性、松弛时间和蠕变)。将这些测量结果与从未怀孕或麻醉的对照组进行比较,并探讨变量之间的相关性。方法回顾性队列研究44例妇女,分为两组。A组:22名女性接受脊髓麻醉治疗CD, B组:22名女性作为对照组。采用压力测量法测量L4-5冈上韧带PPT,并使用MyotonPRO装置评估其生物力学性能。结果两组间PPT差异有统计学意义(P = 0.0001),而刚度、弹性、松弛时间、蠕变差异无统计学意义(P分别为0.318、0.344、0.241、0.227)。PPT与生物力学性能之间也无显著相关性。结论经脊髓麻醉治疗CD的妇女在产后6-12周出现L4-5部位压痛增加、PPT下降,且棘上韧带生物力学变化较小。PPT与这些属性之间的关系可以忽略不计。

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.
