Reliability of Iliotibial Band Morphologic Measurement Using Musculoskeletal Ultrasound Imaging / 中国康复理论与实践

ABSTRACT

Objective To investigate the reliability of the morphologic measure of the iliotibial band (ITB) with musculoskeletal ultra-sound imaging. Methods 20 healthy young subjects were measured with the musculoskeletal ultrasound imaging of the thickness of bilateral ITB at the levels of the femoral condyle by 2 testers, and one of the testers measured again 3-5 days later. The intraclass correlation coeffi-cient (ICC) and minimum detectable change (MDC) were calculated, and the thickness of ITB in both sides was compared. Results The ICC of test-retest was 0.89 (R) and 0.85 (L), and it was 0.82 (R) and 0.84 (L) of inter-testers. The MDC was 0.41-0.51 mm. There was no signifi-cant different between right and left sides for the ITB thickness among healthy subjects (P=0.97). Conclusion Musculoskeletal ultrasound imaging is a feasible and reliable to measure the ITB thickness among young healthy subjects.
