Is it excessive pronation or a lack of pronation control?
Getting on line and googling the term 'pronation' is one of the many things that makes me fairly froth at the mouth.
Go ahead and give it a try, you will find all sorts of lurid images and descriptions, confirming the dire consequences of overpronation. My personal favorite is the 'five red flags of overpronation", the biomecahnical equivalent of the 4 horsemen of the apocalypse!
But really, we need to put that aside, because right now, there is not a single person, in the world, who can adequately tell me what an "overpronater" actually is.
Do not get me wrong, and definitely do not misrepresent me, I am not saying that I do not think that a large degree of subtalar joint pronation cannot be an important contributor, or even cause of musculoskeletal injury. Nothing could be further from the truth,
I absolutely believe it can, but, we MUST stop suggesting that it is always bad, because, it just is not!
A new paper just published really got me thinking about how we might move on with this issue:
Comparison of foot muscle morphology and foot kinematics between recreational runners with normal feet and with asymptomatic over-pronated feet, Zhang et al, Gait & Posture. Volume 54, May 2017, Pages 290-294
The highlights of this paper are as follows:
