Today, Eric Cressey has a guest blog post for you.
I am so excited about the blog post and Eric’s upcoming course at the Fitness & Rehab Conference on March 27 & 28 in Vancouver. I have Eric presenting the whole weekend on corrective exercise for rehabilitation and performance.
Now lets get to the blog post.
One of the most common issues we see in both athletes and our general population clients is a lack of ankle mobility – and more specifically, dorsiflexion range-of-motion.
For just about everything in life – from sprinting, to lunging, to squatting – we need a certain amount of dorsiflexion (think of how far the knees can go over the toes, or the positive shin angle one can create without lifting the heel). If we don’t have it, we have to compensate.
One of the most common things we see in people with a lack of dorsiflexion ROM is an “out-toeing,” as this opens up the ankle and allows for them to get to where they need to be – even if it isn’t the most biomechanically correct way to do so. This out-toeing may also be caused by hip internal rotation deficit (HIRD), so it’s important to assess both. Check out this video for more information on how to assess for HIRD.
