准确可靠的“个体化”腰背竖脊肌(ESM)数据对于评估其产力能力具有重要意义。了解力的产生能力,沿着脊柱负荷,增强了对下背部损伤机制的理解。本研究的目的是建立回归模型来估计ESM横截面积(CSA)。测量值来自大型历史人群的轴向-倾斜磁共振成像(MRI)扫描[L3/L4水平54名女性和53名男性,L4/L5水平50名女性和44名男性,L5/S1水平41名女性和35名男性]。结果表明,一个人的ESM CSA可以准确地估计基于他/她的性别,身高和体重。结果进一步表明,有没有测量和估计的ESM CSA之间的显着差异,预期的绝对误差小于15%。
Accurate and reliable “individualized” low back erector spinae muscle (ESM) data are of importance to estimate its force producing capacity. Knowing the force producing capacity, along with spinal loading, enhances the understanding of low back injury mechanisms. The objective of this study was to build regression models to estimate the ESM cross-sectional area (CSA). Measurements were taken from axial-oblique magnetic resonance imaging (MRI) scans of a large historical population [54 females and 53 males at L3/L4, 50 females and 44 males at L4/L5, and 41 females and 35 males at L5/S1 levels]. Results suggest that an individual's ESM CSA can be accurately estimated based on his/her gender, height, and weight. Results further show that there is no significant difference between the measured and estimated ESM CSAs, and expected absolute error is less than 15%.
