With an overall combined 45+ years of clinical / medical experience in addition to extensive teaching and lecturing experience heavily weighted in biomechanics, neurology, orthopedics, manual medicine, acupuncture, advanced gait and running knowledge,  Dr. Ivo Waerlop (summitchiroandrehab.com) and Dr. Shawn Allen (doctorallen.co & shawnallen.net) are finally bringing what has long been needed to the information/web age, that being enough knowledge and experience to help clarify the truths and dispel the myths that are abundant on the internet and in seminar halls. We are proud to keep our views and opinions on various products truthful and unbiased for the sake of searching for the facts, uncovering the truth and dispelling myths put upon consumers.

This is one of our favorite things to do, podcast.  Every 2 weeks we gather some important information on breaking developments in neuroscience, research, and clinical practice and we sit down and talk for an hour. This podcast has grown faster than either of us expected. We have listeners in countries all over the world. Last time we checked we were in over 90 countries and in places we did not even think spoke, let alone understood, the english language. It is cool to have listeners in Russia, Tasmania, Israel, Japan, South Korea, Chille, Ireland, UAE, Canada, Mexico, Germany, Argentina, Australia, China and the list goes on. We will never get to many of those countries to lecture but it is exciting to know that the internet has brought our voices that far. All you need to do is "Google" us and you will find all the different places where our podcast has been uploaded.  Search "podcast the gait guys". You can always find us on iTunes and download us to your phone or laptop.  We recently started loading them up to our YOUTUBE Channel and SoundCloud. Our thousands of self-authored articles can always be found on our Facebook, Twitter and TheGaitGuys.com   

Enjoy !

1. from Eric on our FB page:

a. Had a 9yr old girl for a shoe fitting recently. She had a forefoot valgus, with a rearfoot that is neutral or slightly varus. Fairly high arch and rigid Midfoot for a child that age as well. usually a child's foot is super flexible so this makes me wonder if it's a compensation for a true FF varus. How do I tell if he has an anatomic FF valgus vs a compensated version?

b. I asked Blaise Dubois his opinion on Treadmill vs outdoor running and he mentioned that the literature indicates TM's aren't much different than outdoor. He cites (Wank 1998). To me, running feels completely different and I can't run nearly as efficiently on a TM as outdoor. i know some people are the opposite, which i subscribe to specificity of training.

the question i have is what basis do you use for your opinion on different motor patterns? i agree with you, but the literature seems to disagree. this is a piece from cybex so of course it will be "pro-treadmill", but they quote several studies that concur with Wank... http://media.cybexintl.com/cybexinstitute/research/Truth_on_Fit_Apr10.pdf

hope i'm not sending too many questions. i figure you can ignore them if you have too many from other listeners.

2. On the Hip Bio Pt 6 you mention ext rot leg to gain leg length.  This one has been racking my brain.  I could see how this could happen if the person supinates the foot at the same time, but is there some other external rotating mechanism occurring in the hip that would cause this lengthening?  Thanks,Ryan

Hi Gait Guys,

I am a chiropractor in South Africa, and find gait, biomechanics and running fascinating...I'm hoping to become a true gait geek one day.Reading your blog has taught me so much, you guys seem to look at gait from every angle and don't take things at face value.

I would like to find out about your Shoe Fit Certification Program. Can people from outside the USA complete the course? Would I be able to take the exam online? and would it give me any creditation in South Africa

 Hope to hear from you soon. 

 Regards, Claire

3. I have been watching your video’s on you tube.  I have a cavus foot in which I have had severe nerve pain, why is the high arch caused by nerve pain?

And would any of your exercises help with my nerve pain

Thanks,Wendy

4. Hi guys,
Found your youtube channel. Very interesting stuff. Have started reading up on the whole gait cycle. Its very interesting. 
I have a quick question that I hope that you can help me with:
Are you aware of any correlation of hip impingement (cam/pincer) in terms of having an irregular gait cycle? 
I am suffering from both CAM & PINCER impingement in my right hip. Had surgery in January, but they did not shave sufficiently off the bone, so going back to surgery soon.
I am therefore interested in seeing how surgery possible could help me with bettering my walk and strain on my lower back / leg / foot. And also in terms of looking into some theory on how to retrain myself in walking cycles. 
The problem is, that this kind of rehab/research is not available here in Denmark. So would appreciate if you are aware of any research on the above, and would be able to point me in the direction of that.
Thank you – and keep those great videos coming. :-)
Best,
Terje (Denmark)
