Should Runners Learn to Dance? Physical Therapy and Performance Implications (Part 2)

In Part 1, we discussed several observations involving the sports of running and dancing.  These observations lay the groundwork for this post, so if you have not read Part 1 yet, I suggest you at least skim it.

Now....some of you may be asking yourselves, "What do these observations mean to me as a runner!?"  Today I'd like to delve deeper into one of my methods for developing functional single-leg stance (adapted for runners from the Selective Functional Movement Assessment).  Remember, this method also applies to the early rehabilitation of dancers, so if you run by day and dance by night, listen closely!

First, let's take a look at dysfunctional single-leg stance:

Do you see how this runner is leaning away from the leg on which he is balancing?  He is unable to stabilize his body through his trunk and lower extremity.  So, if you exhibit dysfunctional single-leg stance like the runner above, how should you go about developing a functional one?

As a sports physical therapist, my first goal is to help teach my patient the feeling of functional single-leg stance.  In other words, I use inexpensive tools to encourage the body to activate the required stabilizing muscles.  Check out the picture below.

**Take note of the 90-degree angle at the L hip and knee as well as the upright trunk position....think of trying to stay pencil-straight from your stabilizing (planted) leg to your head.  Proper positioning of the band involves hanging it around an object like a weight machine or a tree and pulling it towards your body with palms down.  Make sure that you have enough tension in the band.

I am having the patient use a band (can be a piece of Theraband or other stretch-like material) to facilitate activation of the trunk musculature.  One of the main reasons runners display dysfunctional single-leg stance is because they are not able to engage the trunk in concert with pelvic stabilizing muscles and the respective lower extremity.  If you utilize a band as illustrated above, you will notice that you can more easily maintain the single-leg stance position.  At that point, you are beginning to teach your body proper muscle activation patterns, which are extremely important for injury-free running.  How long should you maintain this position?  Enough time to challenge yourself.  Build up to 4-5 sets of 45-second bouts.  When you can maintain functional single-leg stance with the band for 45-seconds at a time repeatedly, retest yourself.  I'll bet that your once-dysfunctional single-leg stance is now functional = minimum of 10-seconds maintaining proper form without losing your balance.  Obviously, additional progressions for this functional movement exist, but the exercise illustrated above is the BASE for more advanced sequences.

Following development of functional single-leg stance, a series of low-level plyometrics is often initiated, beginning with double-leg hops and progressing to single-leg hops.  This portion of the exercise prescription following a running-related injury can be quite tricky and is best completed under the guidance and supervision of a physical therapist who specializes in treating runners.

If you have any questions or comments regarding the information just presented or a personal running-related injury question, feel free to contact me at or via DoctorJunes on Twitter.  I would be happy to help you in any way that I can.  And please, don't be like one of the dance accidents in the YouTube video below!
