Every semester we have interns from the University of Nevada, Reno helping out at our clinic. Here is an example of what we had one of our interns do this afternoon. These are 10 structures that are stretched during one of our knee extension exercises. The intern had to come up with all 10 structures without looking at a textbook or the internet. She could only talk with patients and other employees/interns if she was stumped. However, she only got stuck on the 10th structure, the 9 others she quickly remembered from our Kinesiology class.
