Mean Entropy Results.

	p Value “Normal” vs. “Active”	p Value “Normal” vs. “Normal in Symptomatic”	p Value “Normal in Symptomatic” vs. “Active”
Whole ROI	0.049*	0.246	0.276
Muscle belly	0.083	0.038*	0.381
Fascial border	0.016*	0.275	0.098

ROI = region of interest. A statistical test (Mann–Whitney U test) was performed between mean entropy measured from healthy control subjects and active subjects. “Normal” sites have statistically significant (p < 0.05) lower mean entropy than “active” sites when the whole ROI or only the fascial border are analyzed. Mean entropy evaluated in the muscle belly is significantly higher in “normal” sites than in “normal in symptomatic” sites.
