Reliability and reference values are not well-established for most dynamic sonographic measurements of the median nerve (MN) and flexor tendons that may be used for diagnosing carpal tunnel syndrome (CTS).
Wrists of 20 healthy participants were imaged using ultrasound. Cines of the carpal tunnel inlet were acquired during hand motion. Based on shape and displacement measurements, intra- and interrater reliability and reference values were calculated.
Intraclass correlation coefficients (ICCs) for measurements of the MN and most flexor tendons were ≥0.51 for shape parameters and ≥0.71 for displacement parameters. During motion, the MN flattened with ulnar movement, tendons became more circular, and flexor tendons of corresponding fingers moved toward each other.
Shape and displacement measurements of the MN and most flexor tendons had reliability results ranging from moderate to excellent. The reference values may be useful for the diagnosis of CTS.
用于诊断腕管综合征（CTS）的大多数正中神经（MN）和屈肌腱的动态超声测量的可靠性和参考值尚未得到很好的建立。
使用超声对 20 名健康参与者的手腕进行成像。在手运动过程中采集腕管入口的电影。基于形状和位移测量，计算了内部和外部观察者的可靠性和参考值。
MN 和大多数屈肌腱的形状参数的组内相关系数（ICC）≥0.51，位移参数的 ICC≥0.71。在运动过程中，MN 随尺侧运动变平，肌腱变得更圆，相应手指的屈肌腱相互靠近。
MN 和大多数屈肌腱的形状和位移测量的可靠性结果从中等到优秀不等。参考值可能对 CTS 的诊断有用。
