Policing Gait on the Web

There is some decent information here but we do have some issues with this video. We were asked on our Facebook PAGE to talk about our thoughts on this piece.  We are not trying to criticize anyone, merely helping to keep the information accurate on the web:

1. They are promoting external rotation of the limb into the ground. They refer to this as “screwing” (as they put it) the foot into the ground. The issues here are that the foot supinates when you do this and when you do this too far you weight bear on the lateral foot and disengage the medial foot tripod. They do refer to limits on this but we need to heighten the awareness here. Someone with a forefoot valgus will go to far most likely, and someone with a forefoot varus will disengage the medial tripod quickly.  Most people will also disengage the FHB (flexor hallucis brevis) quickly during this “screwing” technique.  Furthermore, people can also become too dependent on their glutes to hold the “screwed” or supinated position and this is not a safe and reasonable way to support the limb and pelvic posturing. We see this as a very detrimental strategy when sustained PPT (Posterior Pelvic Tilt) is maintained during gait and stance.  There needs to be help from the lower abdominals and adductors as well.   Their “20%” torque is a nice mention and may help many to keep this moderate but this is really dependent on foot type and tibial torsion issues which are not discussed here. As always, not everything fixes everyone, and some things go against an admirable intention.  No digs against these nice fellas, we are just stating what we feel are critical facts not discussed. We watched part 2 and 3 in the hopes of hearing about these issues above, but they were not discussed. We wanted to comment on the videos but they have disabled the comments on youtube.

2. This posturing promotes knee hyperextension which is never good. Go ahead, try it yourself.  You cannot employ a whole lot of this external screwing during gait without changing the knee biomechanics into the hyperextension direction.  It is another reason we mention a caveat here.  If you try it, just pay close attention to what you are doing. You may try to get around the hyperextenion by dropping the pelvis anterior, disengaging your abdominals and changing hip and low back function. 

3. Merely doing what they propose here does not necessarily ramp up the intrinsic muscles of the feet (4:00 mark).  They can remain silent in this maneuver.  Keeping the toes pressed might be more productive to this end.

We watched part 2 and 3 of their Rebuilding the Foot youtube videos and frankly they just scare us a little (go ahead have a look yourself) so we will not comment on anything there. Although we strongly do not advise many of their recommendations in either part 2 or 3 for our clients you may find some stuff you like here … . . heck, who are we to say what you will be willing to try !

To each his own. We give these guys mad props for putting themselves on the net and trying to share their info.  It takes guts to put your stuff on the web, we hope they will enable the comments section so productive dialogues can ensue there in the future.

comments from a follower of the gait guys.

From a reader …..

“From what I’ve gathered from your posts/videos, I have some major issues with my foot function… ie weak Tib Anterior and Extensors.  You have one video up where you demonstrate that a competent foot should be able to keep a solid arch and lower your big toe without losing arch integrity.  I come no where close to this.  In fact, I think it’s pretty amazing at what the foot is supposed to do which is demonstrated by you.  When looking at what Dr. Allen’s foot does and looks like compared to most everyone else’s his seems much more muscular and solid unlike the case studies you put up.  I almost liken most peoples feet to looking like a skeleton with very little muscle mass and function.”

Dr. Allen’s response…….

It has taken me quite a bit of time to get my foot to function this well.  I am lucky in that i know what it is supposed to do and what exercises to implement to get it there.  We have some exercises that we do which we are compiling and will eventually put in DVD format.  We are completing our 3 part shoe fit and foot function DVD for the December Austin Texas IRRA program launch and the completed package should be available end of  January 2012.  Yes, finally they will be done ! There is another reason my foot functions as well as it does……. and we will be sharing some thoughts on this in several weeks once we can compile the information. Hint, awareness and encouraging skill is a big key.  It all starts with Skill……. then build Endurance, and then Strength.  S. E. S. as we say.

Now available for your viewing.

The course by The Gait Guys, Biomechanics 202: Foot Function and the Effects on the Core and Body Dynamics

Whether  you are looking for continuing education credits, or just looking to learn more about true foot function and how it integrates with the rest of the body…….this is a great little lecture.

  • Describe how the motor and sensory homunculus relate to the foot and are integral to training and rehabilitation
  • Discuss the 3 rockers of the foot
  • Give examples of problems that result from a loss of the 3 rockers of the foot
  • Explain the concept of pelvis neutrality and its effect on training
  • Describe and examine the tripod of the foot
  • Breakdown most movement into 2 basic rules or tenets
  • Give examples of the problems which can arise if the 2 basic rules or tenets of movement are not followed
  • Discuss the clinical consequences of loss of the medial and lateral tripods of the foot

Audio Podcast: The Gait Guys, Barefoot Concepts

This is a blast from the past from our parent company, The Homunuculus Group ! Our podcast from 2008 ! Still solid info several years later. Just trying to get you all up to speed before we start up the podcasts here in a month or so.

Here we talk about the foot, intrinsic foot musculature, Nike Free, Vibram 5Fingers and some of Dr. Ivo’s always brilliant  neuromechanical discussions.

Enjoy !
