本研究的目的是确定多裂肌大小和/或肌内脂肪是否与患有或不患有慢性腰痛的老年人的自我报告和基于表现的身体功能相关。病例对照研究 个人参加了临床实验室的标准化评估，并在附近的机构接受了腰椎磁共振成像 (MRI)。二次数据分析中纳入了 106 名社区老年人志愿者样本，年龄为 60-85 岁，患有慢性腰痛 (n=57) 和不患有慢性腰痛 (n=49)。平均左右，L5 多裂相对，即总横截面积 (rCSA)；肌肉脂肪浸润指数（MFI），即肌内脂肪的衡量标准；相对肌肉横截面积 (rmCSA)，即总 CSA 减去肌内脂肪 CSA，由 MRI 确定。以物理功能测量作为因变量进行线性回归建模。年龄、性别和体重指数作为协变量输入。 L5 多裂 MFI 和 rmCSA 的主要影响以及它们与分组分配的相互作用作为自变量进行比较。 Short Form-36 健康调查身体机能子量表 (SF-36 PFS)、计时起身 (TUG)、步态速度和快速下楼梯表现。发现 L5 多裂 MFI 和分组分配之间的相互作用项对所有身体功能测量中解释的方差有显着影响 (p≤.012)。 L5 多裂 rmCSA 的主效应以及与分组分配的相互作用均未对任何身体功能测量中解释的方差产生显着影响 (p>.012)。在患有至少中等强度的慢性 LBP 的老年人中，L5 多裂肌的组成（而不是大小）可能有助于解释身体功能。
The purpose of this study was to determine if multifidi size and/or intramuscular fat were associated with self-reported and performance-based physical function in older adults with and without chronic LBP. Case-control study Individuals participated in a standardized evaluation in a clinical laboratory and underwent magnetic resonance imaging (MRI) of the lumbar spine at a nearby facility. A volunteer sample of 106 community-dwelling older adults, aged 60-85 years, with (n=57) and without (n=49) chronic LBP were included in this secondary data analysis. Average right-left, L5 multifidi relative, i.e. total, cross-sectional area (rCSA); muscle-fat infiltration index (MFI), i.e. a measure of intramuscular fat; and relative muscle cross-sectional area (rmCSA), i.e. total CSA minus intramuscular fat CSA, were determined from MRIs. Linear regression modeling was performed with physical function measures as the dependent variables. Age, sex, and body mass index were entered as covariates. The main effects of L5 multifidi MFI and rmCSA, as well as their interaction with group assignment, were compared as independent variables. Short Form-36 Health Survey Physical Functioning subscale (SF-36 PFS), Timed Up and Go (TUG), gait speed, and fast stair descent performance. Interaction terms between L5 multifidi MFI and group assignment were found to be significant contributors to the variance explained in all physical function measures (p≤.012). Neither the main effect, nor the interaction with group assignment for L5 multifidi rmCSA, significantly contributed to the variance explained in any of the physical function measures (p>.012). Among older adults with chronic LBP of at least moderate intensity, L5 multifidi muscle composition, but not size, may help to explain physical function.
