 note = {Background : Ulnar collateral ligament（ UCL） injury to the elbow is common in athletic populations.
The anterior bundle of the UCL is the main stabilizer against valgus stress on elbow flexion; it provides the
greatest degree of joint stabilization and is therefore the most clinically important component for judo therapy.
Recently, musculoskeletal ultrasound（ MUS） has been used as a new technique in the field of judo therapy.
Because only a few studies have measured the reliability of the UCL using ultrasound, the reliability of
each angle of elbow flexion remains unclear. The purpose of this study was to investigate the measurement
reliability of the UCL thickness and length at each elbow flexion angle（ 30°, 60°, and 90°） using MUS.
Methods : MUS was conducted to evaluate the anterior bundle of the UCL of 10 elbows of 10 healthy
asymptomatic volunteers. The intra- and inter-rater reliabilities were tested using the interclass correlation
coefficients（ ICCs）.
Results : The inter-rater reliability was good to excellent（ ICCs : 0.877–0.951） for the UCL thickness at 60°
and 90° of elbow flexion. At 30° of elbow flexion, the ICCs was good （0.872 and 0.761 for the right and left
arms, respectively）. The inter-rater reliability was excellent（ ICCs : 0.945–0.998） for the UCL length at the
three angles of elbow flexion. The intra-rater reliability was good to excellent （ICCs : 0.804–0.975） for the
UCL thickness at the three angles of elbow flexion in the individual examiners. Similarly, the intra-rater
reliability was excellent（ ICCs : 0.978–0.996） for the UCL length at the three angles of elbow flexion.
Conclusion : The results of this study suggest that the reliability of the UCL thickness and length does not
differ among each angle of elbow flexion using MUS.},
