 Traditionally if you wanted to know whether someone had a ligament injury or some joint problem, you take x-rays, you grab their knee when they're lying on a table, you move it around. And those are very good techniques to understand basic clinical problems, but they don't tell you what's really happening down at the level of the ligaments or the cartilage or the meniscus. And so the types of dynamic imaging that we're developing allow us to get the same kind of information you can get from an MRI when someone's lying on their back in a big tube. We can get the same kinds of measurements for people who are running or jumping or moving in a way that's important to them. We're working with Dr. Philippa and looking for more acetabular impingement, trying to understand why certain athletes develop this pony deformity and why in some it becomes symptomatic and some it doesn't. Working with Dr. Provencher on a study to improve techniques for assessing when an athlete or perhaps a soldier is ready to return to sports or return to duty after an ACL injury or another type of knee injury by again focusing on how they're performing during activities that are most relevant for them as opposed to the sort of standard return to sports assessment that people are using now the same for everybody. So again it's that idea of personalized approach to medicine. We're now well into our development of a ski safety program looking at modifications to ski equipment that we think are going to improve balance and performance in individuals in particular looking at differences between men and women and their specific equipment needs. It's like so much research the more questions you ask the more questions you create but that's what keeps driving us forward that's what keeps it interesting and we know we're never going to run out of things to look at.
