The study aims to investigate the relationship between abdominal muscle activity and the cross-sectional area (CSA) of the lumbar muscles and assess their role in the functional assessment of patients with chronic non-specific low back pain (CNSLBP).
142 patients with CNSLBP were included in this study. Disability levels were evaluated with the Roland-Morris Low Back Pain and Disability Questionnaire. The functional assessments of the participants were evaluated with a 6-minute walk test. Abdominal muscle activity was measured using a pressure biofeedback unit. The CSA of the bilateral multifidus, erector spinae, and psoas muscles were measured T2-weighted MRI images at the L2-L5 levels.
Significant correlations were found between the abdominal muscle activity during the posterior pelvic tilt movement and the CSA of the erector spinae muscle at the L4 and L5 levels, and the psoas muscle at the L2-L5 levels (correlation coefficient range from 0.32 to 0.48). Abdominal muscle activity yielded a significant additional contribution to the variance on the functional assessment (R change=0.101).
The relationship of abdominal muscle activity with lumbar muscles and the contribution of muscle activities to functional assessment should be considered in the management of patients with CNSLBP.
本研究旨在探讨腹肌活动与腰椎肌肉横截面积（CSA）之间的关系，并评估其在慢性非特异性下腰痛（CNSLBP）患者功能评估中的作用。
本研究纳入了 142 例 CNSLBP 患者。采用 Roland-Morris 下腰痛和残疾问卷评估残疾程度。采用 6 分钟步行试验评估参与者的功能评估。使用压力生物反馈单元测量腹肌活动。在 L2-L5 水平上，使用 T2 加权 MRI 图像测量双侧多裂肌、竖脊肌和腰大肌的 CSA。
在后骨盆倾斜运动期间的腹肌活动与 L4 和 L5 水平的竖脊肌以及 L2-L5 水平的腰大肌 CSA 之间存在显著相关性（相关系数范围为 0.32 至 0.48）。腹肌活动对功能评估的方差有显著的附加贡献（R 变化=0.101）。
在 CNSLBP 患者的管理中，应考虑腹肌活动与腰椎肌肉的关系以及肌肉活动对功能评估的贡献。
