Ultrasound Imaging of Quadriceps Muscle in Patients With Knee Osteoarthritis

Official title:
Ultrasound Imaging of Quadriceps Muscle in Patients With Knee Osteoarthritis: Reliability of Echo Intensity Measurement

Clinical Trial Summary

Echo intensity (EI) assessment using ultrasonography helps monitoring disease-induced muscle quality changes. However, there are no study investigating the reliability of EI in patients with knee osteoarthritis (OA). The primary aim of the present study was to investigate the inter and intra-rater reliability of EI evaluation by grayscale histogram analysis of quadriceps femoris muscle in patients with knee OA. The second aim was to compare the mean grayscale values obtained using both the Free Hand Tool (FHT) and Rectangular Marquee Tool (RMT) methods in ImageJ. Thirty patients with knee OA were included in this cross-sectional study. The echogenicity measurements of the Rectus Femoris, Vastus Inter-medius, Vastus Lateralis and Vastus Medialis were performed by two different researchers. Reliability analysis of EI measurements were calculated with using intraclass correlation coefficient (ICC), standard error of measurement (SEM) and coefficient of variation (CV) and Bland and Altman plot analysis.
