简要总结
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.

Muscle Echogenicity Assessment ( Physiological parameter)
时间窗: Thirty minute
Muscle echogenicity assessed by using ultrasound. Ultrasound assessment was performed on rectus femoris (RF), vastus intermedius (VI), vastus medialis (VM) and vastus lateralis (VL) muscles using with an ultrasound-imaging device (Philips Medical Systems EPIQ 5 Release 5.0.2, Amsterdam). Ultrasound Brightness mode (B-mode) with musculoskeletal scanning and a multi-frequency linear transducer (8-12 MHz, code: eL18-4) were used. For calculating echogenicity of muscles; all images obtained ultrasonography were analysed using the Image J software (Version 1.48v, National Institutes of Health, Bethesda, MD, USA) by two different analysers (five years and one-year of experience in US image analysis). The echogenicity results of the muscles performed by the two researchers recorded.
