The purpose of this study was to assess the test-retest reliability of tendon excursion measurements with color Doppler imaging in patients with flexor tendon injuries following a modified Kleinert protocol.
One observer performed repeated measurements at 3 different time periods in 13 patients with flexor tendon injuries, following a modified Kleinert protocol. The intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and related indices of measurement error were calculated.
Measurements at 10 day after surgery had an ICC of.88 and an SEM of 1.1 mm. Measurements at 6 weeks after surgery had an ICC of.58 and an SEM of 2.0 mm. The measurements after 3 months had an ICC of.94 and an SEM of 1.2 mm.
Measurements at 10 days and more than 3 months after surgery were reliable and were as reliable as the measurements performed on healthy subjects. At 6 weeks after surgery the measurements were less reliable. Color Doppler imaging is a reliable and noninvasive method to assess tendon excursion, even in patients with small tendon excursion movements.
本研究旨在评估采用改良Kleinert方案的屈指肌腱损伤患者中，使用彩色多普勒成像测量肌腱滑动的重测信度。
一名观察者对13例屈指肌腱损伤患者按照改良Kleinert方案，在3个不同时间段进行重复测量。计算组内相关系数（ICC）、测量标准误（SEM）以及测量误差的相关指标。
术后10天测量的ICC为0.88，SEM为1.1毫米。术后6周测量的ICC为0.58，SEM为2.0毫米。术后3个月测量的ICC为0.94，SEM为1.2毫米。
术后10天及3个月以上的测量结果可靠，与对健康受试者进行的测量结果一样可靠。术后6周的测量结果可靠性较低。彩色多普勒成像即使在肌腱滑动幅度较小的患者中，也是一种可靠且无创的评估肌腱滑动的方法。
