Today’s show notes:

Neuroscience piece:

McPartland et al (2005) measured Anandamide (AEA) levels pre- and post, Myofascial Release, Muscle Energy Technique, High velocity manipulation all of which load fascia patients experienced analgesic/euphoric cannabimimetic effects, which correlated with an increase in serum AEA levels (more than double pre-treatment evels). 
Neither cannabimimetic effects, nor changes in AEA levels, occurred in control subjects.

Hi Guys: Not quite sure how I came across your podcasts but really enjoying them, even if I’m only slowly starting to understanding them. I was catching up on some old ones during my marathon training and the ones on evolution reminded me of some of my musing on the arch in the foot (well I guess correctly that should be the medial longitudinal arch). I though you might be able to give me the answers or point me in the right direction

Are we only species with this?
What is the advantage?
When and how does it develop and why isn’t it formed in utero?
Are flat feet then a genetic or developmental issue and why?

7. Another TUMBLR reader asks question about:
Hi Gait Guys,

I am currently a third year podiatry student needing some biomechanics and orthotic-making training. I enjoy your youtube videos but was wondering if you offer or could recommend a dvd that I could purchase to further my education. The way the information is presented it in class is not as good as the way you do it! I am also interested in the biomechanics of shoes… I am having trouble finding information about how walking in a cushioned/plantarflexed sneaker effects function (Does is help us get to forefoot running or hinder us?). I enjoyed your blog on different curved lasts as well. How would I be able to apply the way the shoe is lasted to a patient? For example, if the patient is rigid and I want them to be wearing a shoe that is lasted like a slipper how do I guide them into buying a shoe constructed as such? Do I just tell them to go for a shoe made with a straight toe box? Is there such a thing as a toe box curved laterally? 

One last question- do you recommend a medial FF post for a patient that has a mobile RF varus that causes a FF supinatus? I was told a post like this would limit PF of the first ray and DF of the hallux which would limit toe off and cause other problems. 
Thank you. I appreciate any advice you may have. I am out of my element with biomechanics and really want to improve at it.

sign-life-away asked you:
Is forefoot walking bad for you? Everyone says I walk awkwardly, as if i have something up my bum. I have been trying to walk “naturally” (heel-toe) but I go back to forefoot strike. Does this contribute to why my legs have always been muscular?
