Reliability of Measuring Coracohumeral Ligament Stiffness with Different Shoulder Positions of Frozen Shoulders.

ABSTRACT:

Background

Shear wave elastography (SWE) is utilized to detect the stiffness of the coracohumeral ligament (CHL) for the assessment of a frozen shoulder. However, the consistency of shoulder joint posture during the detection process has not been adequately established. This study aims to evaluate the reliability of various commonly employed shoulder postures in measuring CHL stiffness.

Methods

SWE was used to assess CHL stiffness in 55 patients with phase I frozen shoulder by two independent observers. Two measurements were taken, with a 1-week interval, at three shoulder positions: neutral, 30° external rotation, and 60° external rotation. The intra- and inter-observer reliability of CHL stiffness measurements were analyzed using a two-way randomized model with an intragro
