本研究的目的是建立11周至16岁儿童肌肉厚度、肌肉厚度与皮下脂肪厚度的比值和肌肉回声强度的正常值。采用标准化实时超声检查方法对四块肌肉进行横断面扫描。扫描被数字化，并用灰阶分析测量平均回声强度。使用多元回归方程来研究哪个独立参数(年龄、身高、体重或性别)影响每块肌肉的变量。肌肉厚度取决于孩子的体重。校正体重后，其他参数对肌肉厚度没有显著影响。肌肉厚度与皮下脂肪厚度之比取决于年龄。回声强度与这两个变量中的任何一个都没有相关性。因此，所有的正常值，包括计算它们的方程，都会被描述。这些正常数据可能有助于确定肌肉超声对疑似神经肌肉疾病儿童的诊断价值。
The purpose of this study was to establish normal values of muscle thickness, ratio of muscle thickness to subcutaneous fat thickness, and muscle echo intensity in children between 11 weeks and 16 years of age. Transverse scans of four muscles were made by standardized real-time ultrasound examination. The scans were digitized, and mean echo intensity was measured using gray-scale analysis. A multiple regression equation was used to study which independent parameter (age, height, weight, or sex) influenced the variables for each muscle. Muscle thickness depended on the child's weight. The other parameters did not significantly influence muscle thickness after correction for weight. The ratio of muscle thickness to subcutaneous fat thickness depended on age. Echo intensity showed no correlation with either of the variables. As a result, all normal values, including the equation to calculate them, are described. These normal data may help to determine the diagnostic value of muscle ultrasound in children with suspected neuromuscular disease.
