摘要：

目的:探讨单侧下背痛患者脊柱核心肌群的变化,为指导制定下背痛运动治疗方案提供一定的研究依据。方法:178例单侧下背痛患者根据病程长短分为急性期组(n=76)和慢性期组(n=102),采用Onis软件和Image J软件分析受试者腰部MRI图像,比较痛侧和非痛侧腰大肌(PM)、腰方肌(QL)、多裂肌(MF)和竖脊肌(ES)的肌肉横截面积(CSA)、肌肉平均信号强度(MSI)和脂肪浸润(FI)比例。结果:急性期组中,痛侧PM和ES的CSA较非痛侧肌肉小(P<0.05),MSI和FI比例较非痛侧肌肉高(P<0.05);慢性期组中,痛侧MF和ES的CSA较非痛侧肌肉小(P<0.05),MSI和FI比例较非痛侧肌肉高(P<0.05);急性期组痛侧ES的CSA较慢性期组痛侧肌肉大(P<0.05),MSI和FI比例较慢性期组痛侧肌肉低(P<0.05)。结论:急性期组和慢性期组患者存在痛侧竖脊肌的肌肉萎缩和脂肪浸润,慢性期组患者痛侧多裂肌萎缩明显。通过MRI研究LBP患者腰椎核心肌群情况,可为出现异常变化的肌肉设计针对性训练动作和方法提供依据,有助于尽快恢复脊柱力学,改善功能障碍。
