Topic: Foot Mechanics
Posted By: ProfessorRothbart
Subject: Foot Mechanics
Date Posted: 01/31/2021 at 6:25am
I have been a researcher and medical clinician for over 50 years.  My area of interest is the impact foot mechanics has on sport performance.
Is there interest in starting a discussion on the impact that abnormal foot pronation (e.g., gravity drive pronation) has on body mechanics (and ultimately level of performance)?

Please share your thoughts!
Really interested in it.

Abnormal ( http://athletics.fandom.com/wiki/Gravity_Drive_%28Abnormal%29_Pronation" rel="nofollow - gravity drive ) foot pronation results in torsional mechanics, foot to jaw.  The result is diminished performance in any and all sports.

Normal ( http://athletics.fandom.com/wiki/Hip_Drive_%28Normal%29_Pronation" rel="nofollow - hip drive ) foot pronation results in linear mechanics, foot to jaw.  The result is optimal performance in all sports.

Take a look at these two websites describing the difference between the two and then we can continue this discussion.

I remember one person posted a video of themselves doing fh vs a robot.  Everbody else was looking at the swing.  What stuck out to me was that he was "the opposite of pigeon toed".  Many players rock back onto their heels too, I've noticed, if they don't have their toes pointed right.

It's something I look at first from my ryu kyu kempo days.  There was a lot of attention paid to where you toes point when you're doing a kata

can't say I could glean much from those links though.  I'm not smart enough to make heads or tails of what it was saying

Hint - a common observation when dealing with torsional mechanics is an abducted (toes pointed outward) stance and gait

Hi Dr Rothbart,

Thank you in advance for reaching and sharing your science about pain inflicted by sports or any activity.

I am not done with reading your fancy http://www.rothbartsite.com" rel="nofollow - website and the materials to which you linked above but... 

Ouch! toes pointing outwards with weigh transfer inwards when unloading a FH loop means bad news for the playing knee and ankle doesn't it? It hurts only thinking about it.

WELCOME!

Idk man, most people have normal feet I think?

Ankle and feet injuries aren't all that common in TT I think... Most of it is knees, lower back, elbow, shoulder.

On the contrary, Achilles tendon problems are common in TT.  Knees and back, shoulder a d elbow too of course.

Linked below is an interesting thread from the world of podiatry.  I am curious how long the thread here will get before the OP tries to sell us all some insoles?

Thanks. This is interesting. I've actually had some minor issues with my right ankle while playing table tennis for a while now. Nothing major, but enough to make me think something could be up.

Hopefully this helps!

I kind of figured, but still interested.  Not in insoles. My feet are among my healthier parts.

It won't to me.  I couldn't help noticing that you have advocated insoles for treatment of everything from women's fertility problems to dental issues.  

If it makes sounds like a duck....

Just to clarify.  I am retired from practice, nothing to sell.  I am now strictly in research.  You can access my http://www.researchgate.net/profile/Brian_Rothbart" rel="nofollow - researchgate site , if you so desire.

Now, let us proceed.  I have always been interested in the link between body mechanics and level of performance in sports (all sports, including table tennis).  

Ideally, all weight bearing joints should function around their anatomical neutral position (e.g., joint congruity).  This results in (1) linear mechanics which (2) automatically results in a minimal expenditure of energy in performing the task at hand.  This translates into optimal performance.

Conversely, if the weight bearing joints are forced to function around a skewed position (a position that alters the weight joints away from their anatomical neutral position), the athlete is (1) engaged in torsional mechanics which (2) automatically forces the athlete to expend a greater amount of energy to perform the task at hand.  This translates into a compromised level of performance.

If this interests you, I will continue.

Hi,

This I know: in the 1970's, rapt attention was paid to the deified Istvan Joyner's forehand loop and all its details, as his forehand loop confirmed the proposition declared in a pop song by Belinda Carlisle that "heaven is a place on earth" in the form of Mr. Joyner's forehand loop.

In the cases of proper positioning, (as a right hand player) his right foot pointed perpendicular to the path of his shot and his left foot pointed forward in the direction of the shot.

Thanks.

The salient issue is: is the joint in question functioning around its anatomical neutral position (linear mechanics) or is it forced to function around an altered position (torsional mechanics).

The effectiveness of Joyner forehand loop was most likely the result of linear mechanics.  This is true in all sports.  Those athletes who are the elite of the elite almost invariably have been blessed with linear mechanics.

Let me be more specific:  Speed, power, consistency of form, prone to resist overuse injuries are all subsets of mechanics.  They are enhanced with linear mechanics, compromised with torsional mechanics.

Once that is understood, the next logical question would be:  If one is born with torsional mechanics (and indeed it is an inherited trait), how can it be reversed.  That is kernel of my research, reversing torsional mechanics.

I've already been to your Research Gate site.  More importantly I've been to PubMed to see what you've done that had at least some degree of peer review and the kind of thing that in your mind passes for evidence.  Actually comparing the two is itself informative. 

It certainly looks like you still have a website selling insoles.  

I'm not planning to engage with you further, because like I said, I've seen enough already.  More than enough.  But I will be keeping an eye on things here.

Apparently so.

Level of Performance in all sports revolves around the issue of Torsional mechanics.  The Russians have understood this for several decades.  In the United States and Europe it still is poorly understood.

If there is interest to discuss this in more detail, I would be happy to do so.

OK, I can't resist noting that  the Russians certainly understood the effects of doping on athletic performance for decades and attributing their perfomance in sports to something related to podiatry is a very big stretch. 

Turns out that "Professor" Rothbart still has a website where he sells his services through a telephone consultation.  (I'm not going to link to it). 

He modestly calls himself "the Father of Chronic Pain Elimination".  He claims to have discovered something called Rothbart's Foot.  A search of Pubmed (the definitive repository of peer-reviewed biomedical publications) shows not a single publication from anyone referring to this condition, indeed any reference he himself has made to it does not appear in any journal indexed in PubMed.  There are always places that look like medical journals where you can publish pretty much any sort of quackery, and people who are not in the business can be easily taken in.     

Also on his website that I won't link to, he indeed does sell his insoles, apparently based on a telephone conference and his "proprietary" analysis of photos that you send him. Maybe he is not as retired as he claims (and he's doesn't seem to be a professor anywhere at the moment).  There are also  lots of patient "testimonials", which (and here is a pro tip) is almost always a sign of quackery.  But he wants you to know that he only takes on 20 patients at a time because his services are so valuable.  He also lists membership in so-called medical societies that are highly questionable by the following criteria:

https://en.wikipedia.org/wiki/Alternative_medicine" rel="nofollow - https://en.wikipedia.org/wiki/Alternative_medicine

I could go on, but this thread will not do anyone any good.  Time to lock it up.

One last thing, if you really do have foot or ankle problems, go see a podiatric physician or a specialist in orthopedics who works near where you live.  They will actually examine you, do whatever diagnostic imaging and functional analysis is necessary, and recommend a therapy.
