Figure 2

An example of a postural reflex response to sudden loading (muscle obliquus abdominis externus). Instance of load drop (): 200 ms window for analysis () and 50 ms reference window for calculating baseline EMG activation are shown. The arrow depicts the muscle activation onset, solid line depicts the linear convolution, and the dotted line depicts the root mean square (RMS).
