简介：对于大多数可用于诊断腕管综合征（CTS）的正中神经（MN）和屈肌腱的动态超声测量，可靠性和参考值尚未建立。方法：对20名健康受试者进行腕关节超声成像。腕管入口的线条是在手部运动中获得的。根据形状和位移测量结果，计算了井内和井间的可靠度和参考值。结果：MN和大多数屈肌腱测量的类内相关系数（ICCs）为>= 0.51的形状参数和>= 0.71的位移参数。在运动过程中，MN随着尺骨运动而变平，肌腱变得更圆，相应手指的屈肌腱相互移动。结论：MN和大多数屈肌腱的形状和位移测量具有中等到优异的可靠性结果。这些参考值对CTS的诊断有一定的参考价值。
Introduction: 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). Methods: 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. Results: 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. Conclusion: 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.
