Abstract:
Objective To measure the Young's modulus values of the quadriceps muscles(rectus femoris,vastus intermedius,vastus lateralis,vastus medialis)and tendons in Parkinson's disease(PD)patients using real-time shear wave elastography(SWE)technology,and to analyze the changes in muscle and tendon tone.Methods A total of 60 clinically diagnosed PD patients from Yunnan University Affiliated Hospital between April 2023 and April 2024 were included in the study group.Based on the scores and ratings of PD rating scale,patients were divided into Group A(symptomatic side,n=60)and Group B(less symptomatic side,n=60).An additional 60 healthy subjects were selected as the control group.The shear wave elastography function of the ACUSON Sequoia ultrasound diagnostic device from Siemens USA was used to measure the Young's modulus values(kPa)of the quadriceps muscles and tendons in a relaxed state,and to analyze and compare the changes in muscle and tendon tone.Results The Young's modulus values of quadriceps muscles(rectus femoris,intermedius femoris,vastus lateralis,vastus medialis)in groups A and B were higher than those in control group(P<0.05).The Young's modulus values of the intermediate and lateral femoris muscles in group A were higher than that in group B(all P<0.05).The Young's modulus values of quadriceps tendon in groups A and B were higher than that in control group.(P<0.05).The Young modulus value of quadriceps tendon in group A was higher than that in group B(P<0.05).Conclusion Patients with Parkinson's disease exhibit increased muscle and tendon tone in the quadriceps.Notably,the muscle tone of the vastus intermedius and vastus lateralis on the symptomatic side is higher than that on the less symptomatic side,while there is no significant difference in muscle tone between the rectus femoris and vastus medialis on the symptomatic and less symptomatic sides.
