Fig. 7

Scatter plot comparing MLE- and IPE-measured CV values from 22 S-EMG signals measured on the biceps brachii muscle of healthy volunteers, during 10-s isometric contractions, at 20 % of the MVC. The red dashed line is the identity line and the green dashed line is the regression line. The correlation coefficient was 0.99 (\(p < 0.01\)), the slope of the regression line was 1.06, and its linear coefficient was −0.24 m/s
