通过人体测量来估计肌肉横截面积（CSA）对于客观临床研究不敏感。然而，计算机断层扫描（CT）能够进行特定的肌肉成像，以准确确定CSA。本研究涉及15名既往膝关节损伤的男性，研究了双侧CT在计算大腿中部肌肉密度（Houndsfield单位：HU）和股四头肌萎缩方面的可重复性。观察到肢体之间的力量（p<0.0001）、CSA（p<0.001）和HU（p<0.05）的显著差异。在为期四周的电运动刺激（EMS）计划之前，力与股四头肌CSA之间存在显著相关性，但随着时间的推移，这种相关性逐渐减弱。在没有CSA增加的情况下，神经源性对力量改善的贡献得到了证实。这些数据表明CSA不是萎缩肌肉力量潜力的可靠预测因子。计算机断层扫描为标准化组织密度和肌肉CSA评估提供了准确、可重复的方法。
The estimation of muscle cross-sectional area (CSA) by anthropometric measurements is insensitive for objective clinical research. However computed tomography (CT) enables specific muscle imaging for accurate CSA determination. This study, involving 15 males with previous knee injuries, examined the repeatability of bilateral CT in calculating mid-thigh muscle densities (Houndsfield units: HU) and quadriceps atrophy. Significant differences between limbs in strength (p<0.0001), CSA (p<0.001) and HU (p<0.05) were observed. Prior to a four week electro-motor stimulation (EMS) programme, a significant correlation between force and quadriceps CSA existed which diminished over time. Neurogenic contributions to improved strength were demonstrated in the absence of increased CSA. These data suggest CSA is not a reliable predictor of strength potential in atrophic muscle. Computed tomography scanning provides an accurate, repeatable method for standardized tissue density and muscle CSA assessment.
