Cross-Sectional Nakagami Images in Passive Stretches Reveal Damage of Injured Muscles

Figure 5

Regression analysis confirmed that mechanical forces were highly correlated to echogenicity (a) and Nakagami (b) parameters in longitudinal images for both normal (black solid squares) and injured (red open squares) muscles. The echogenicity also showed moderate correlation with mechanical stress in cross-sectional images (c). The injured muscle showed low correlation between cross-sectional Nakagami parameters and mechanical stresses (d).
