The University of Wisconsin Madison was selected to do extra research on hamstring injuries for NFL football players. The NFL awarded the University of Wisconsin a grant through the league’s effort to learn more and combat injuries to lower extremities. Several researchers will use word-class quantitative imaging, analytics determining risk factors, and on-field bio-mechanics. The goal for the study is to pave the way for future research that involves orthobiologics as a treatment for muscle strain type of injuries.
