摘要:The objective of this study is to explore the feasibility of using shear wave elastography(SWE) to in vivo, noninvasively and quantitatively measure mechanical properties of important muscles around the human knee joint. Eight healthy males were recruited to participate in the study, and the mechanical property(Young‘s modulus) of 10 muscles of each participant was measured in seven standard test positions: supine, prone, sitting, and four quasi-static walks by using SWE. Results indicated that the ICC1,1 ranged from 0.953 to 0.987, and the 95% CI was in the range 0.836–0.992 for all the tested muscles. This indicated that the Young‘s modulus of the muscles, measured by SWE, exhibited excellent retest reliability. In the supine, prone, and sitting positions, significant differences were observed in Young‘s modulus of the other 9 muscles tested in different positions(P<0.05) with the exception of biceps femoris(BF). The results demonstrated that the SWE measurements of the Young‘s modulus can be used to accurately reflect the kinematics changes in muscles involved in human motion, and this verified the feasibilities of using SWE to make real-time and quantitative analysis of single muscle mechanical properties.
