PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
