60 second audio pod. Our mental state changes our gait, and our gait changes our mental state.
We highly suspect that this is not the “bouncy” gait we typically refer to, the loss of ankle rocker gait.
The Bouncy Gait: Premature heel rise gait. Taking another look.
This is a great video example of a premature heel rise during gait. You should be able to clearly see it on the left foot (and this was toned down after we brought it to his awareness!). The heel rise occurs early in the stance phase of gait, instead of the late stance phase.
We have talked about this bouncy type vertically oriented gait many times in blog posts and in our podcasts. This is a pretty prevalent problem in the world, mostly because so many people have impaired ankle rocker/dorsiflexion from weak anterior compartments and short/tight posterior compartments. None the less, for the majority, this is a pathologic gait pattern and it will impart undue stress into the posterior mechanism (calf-achilles complex). Just think about it, this person is going vertical at or prior to the tibia achieving 90degrees (perpendicular to the ground) instead of continuing to progress the tibia to 110+ degrees to enable normal timely pronation and foot biomechanical events. This is not a normal gait. Period. This will change the function of the entire posterior chain upward.
If you want to see another great example from the frontal plane, check out this cute video representation of a vertial/premature heel rise bouncy gait.
This gait style is caused by a premature heel rise from joint range limitation and/or from premature engagement of the gastrosoleus (and sometimes even the long toe flexors, you will see them hammering and curled in many folks). It can be a learned habitual pattern and nothing more, we have even seen it even in child-parental gait modeling in our offices. These people will never get to NORMAL full late-midstance of gait (without biomechanical compromise) and thus never achieve full hip extension nor adequate ankle dorsiflexion / ankle rocker. The gait cycle is an orchestrated symphony of timely events and when one or several timely events are omitted or impaired the mechanics are passed into other areas for compensation. This vertical gait style is very inefficient in that the gluteals cannot adequately power into hip extension into a forward progression drive, because the calf is prematurely generating vertical movement through ankle plantarflexion. This strategy is sometimes deployed because the person actually is significantly ankle dorsiflexion (ankle rocker) deficient. Meaning, they hit the limitations of dorisflexion and in order to progress forward they first have to go vertical. This vertical motion, because they are moving into ankle plantarflexion, re-buys more ankle dorsiflexion range which then can be used if they so choose. Obviously, the remedy is to find the functional deficit, remove it and retrain the pattern. There are a whole host of other problems that go with this compensation pattern but we wanted our mission to stay focused today. Remember, this is usually a subconscious motor pattern compensation. Is it like the toe walking issue we talked about last week (post link here) ? It is similar in some ways and can have primitive and postural motor pattern implications. We will follow up the “Idiopathy Toe Walking Gait: Part 2” shortly but we wanted to strategically put this blog post ahead of it, because there are similar characteristics and implications. Trust us, there is a method to our madness 🙂

a. I was listening to pod 49, great job. I am sending a personal message to point out an error regarding body composition. Under water weighing is considered the 2 compartment “Gold Standard” however caliper testing is used more due to cost and ability to be used in the field. Loved the learning stuff I sent some stuff similar to what you were talking about to the school administration but it went no where.
Thanks guys, Mark

Not very infrequently the foot tripod has been discussed. Especially the importance of the medial tripod (MT) has been of great benefit to me. Some kind of a peroneus paralysis was probably the cause of weak MT of the right foot. With a weak anterior muscle group or compartment. But what about the lateral tripod, ie the 5th distal end of the fifth metatarsal. Which muscles are most responsible for the foot stability here and what kind of exercises might be of therapeutic value? Thank you.

Dear Gait Guys,
I’ve had a problem for a while where my lower left leg whips across the midline of my body at the start of the swing phase. This happens immediately after my left foot leaves the ground and before my right foot makes contact. My left knee seems to be angled outward, and I think this is due to some sort of external rotation of the hip or femur during the the early part of my swing phase. I attached a picture to illustrate this problem in my gait. I recently came across a blog post you guys wrote (http://thegaitguys.tumblr.com/post/14262793786/gait-problem-the-solitary-externally-rotated
) and under the possibilities as to why there isn’t enough internal rotation, the second option describes exactly what happens when I run. So my question is, what can be done to correct this improper gait pattern? Thank you very much for taking the time to read this.

This is one of our all time favorite gait styles. Aside from the atonic arm swing, what we love about this one is the vertical nature of this gait style. If you look around you will see this one often. These are the bouncy folks. There is a bucket load of vertical body movement when in fact the head should stay static in gait and in running.
This gait style is caused by a premature heel rise from premature engagement of the gastrosoleus (and sometimes even the long toe flexors, you will see them hammering and curled). The person will never get to full late-midstance of gait and thus never achieve full hip extension nor adequate ankle dorsiflexion / ankle rocker. These are timely events and specific things are supposed to happen during these phases of gait that are omitted and thus passed into other areas for compensation. This gait style is very inefficient in that the gluteals cannot power into hip extension into a forward progression drive, because the calf is prematurely generating vertical movement through ankle plantarflexion. This strategy is sometimes deployed because the person actually is significantly ankle dorsiflexion (ankle rocker) deficient. Meaning, they hit the limitations of dorisflexion and in order to progress forward they first have to go vertical. Obviously, the remedy is to find the functional deficit, remove it and retrain the pattern. We will be going over this pattern quite a bit in our new DVD line when we can get to it, because there are other deficits that could drive this one such as short hip flexors and quads to name one.
