and what have we been saying about loss of ankle rocker and achilles tendon problems for years now?
Here is a FREE, FULL TEXT article talking all about it
“A more limited ankle Dorsi Flexion ROM as measured in Non Weight Bearing with the knee bent increases the risk of developing Achilles Tendinopathy among military recruits taking part in intensive physical training.”
J Foot Ankle Res. 2014 Nov 18;7(1):48. doi: 10.1186/s13047-014-0048-3. eCollection 2014.Limited ankle dorsiflexion increases the risk for mid-portion Achilles tendinopathy in infantry recruits: a prospective cohort study.Rabin A1, Kozol Z, Finestone AS.

Screens are valuable. But, only if they screen all the pertinent areas, only if the screener knows what to look for, and only if one realizes they are just a screen and not a platform for corrective exercise prescription. Guys like us and Gray Cook have been saying this for years.
Are we the only ones that did a “face palm” after reading this study? I mean, “duh”. Or are we missing something ?
Pronation gets more dorsiflexion all on its own so how in the world can this be a translatable study ?
Besides, in the pronation posture, length if achieved was perhaps mostly medial gastrocoleus divisions.
And……was the knee bend or straight? Hint: This matters, both those posterior muscles do not cross the knee, only one does.
Conclusion: After a 3-wk gastrocnemius-stretching program, when measuring dorsiflexion with the STJ positioned in supination, the participants who completed a 3-wk gastrocnemius stretching program with the STJ positioned in pronation showed more increased dorsiflexion at the ankle/rear foot than participants who completed the stretching program with the STJ positioned in supination.

New connections and pathways are fragile and only through repetition and practice and focused attention can those connections be established enough to become habitual or default behaviors.

The eccentric aspect of the shuffle walk
I’m an Osteopath from Australia and am a keen follower of your work. I just had a quick question about your tib ant training via the shuffle gait. I am comfortable with the theory behind it, my only issue is that clinically, tib ants role as an eccentric controller of pronation is significant. Therefore, shouldn’t we develop an exercise which trains it in an eccentric fashion? perhaps there is some controlled pronation in the shuffle gait that I have missed, but i’m interested to hear your thoughts as they are thoughts I respect!
Thanks very much for all your work, it’s great to see practitioners using evidence based practice in a creative and practical way.
Hi D. Good question and it is a major point.. If you think about the exercise, you are slowly putting the ball of the foot back on the ground AND maintaining the arch as best as possible. In essence, the arch will drop a bit as your weight is born on the foot, so it will pronate, but you are trying to hold it up, so in a manner of speaking you are controlling the arch descent, so you are eccentrically focusing on the activity. If we were to reshoot the video, this would be part of teh dialogue, because we do have our clients focus on this. Remember, we are giving this exercise to many folks who have pronation control issues (yes, and ankle rocker issues) so we are kinda hitting the aspect you are questioning. How this helps a bit. As they get better, they take bigger steps in the shuffle walk, so that means more acceleration of the prontation, so they will have to try to maintain the arch under greater loads…….hence, more eccentric focus. That is the way we see it anyways.
