Abstract: Backgroud: Strain elastography (SE) and shear wave elastography (SWE) are emerging techniques for evaluating the elasticity of soft tissue. This study aimed to determine interobserver and intraobserver reliability for elasticity measurements of different tissues and anatomic locations using SE and SWE. Methods: Ten healthy adult male individuals with 20 upper extremities participated in this study. The elasticities of the wrist extensor muscle, the common extensor tendon, and supraspinatus tendon were measured. Strain ratio and shear wave velocity were measured twice by 2 different examiners (examiner 1 with over 20 years of experience in musculoskeletal sonography and examiner 2 with 1 year of experience). Interobserver and intraobserver reliability was assessed using the intraclass correlation coefficient (ICC). Results: = 0.008, respectively). Conclusions: SWE is a reliable method for assessing the flexibility of soft tissue, but it is affected by expertise and the specific anatomical site.
