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 ( and Dr. Shawn Allen ( & 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   

Enjoy !

Neuroscience piece:

1.Superhuman sight and hearing.
2. Kickstart device

Kickstart from Cadence Biomedical is designed to help improve the gait of people who have difficulty walking and help them regain their mobility and independence. But unlike its robotic cousins that are powered by weighty rechargeable batteries, the Kickstart is able to ditch the batteries altogether because it has no motors to power. Instead, it is purely mechanical and provides assistance by storing and releasing kinetic energy generated by a person when walking.

3. Bionic ear
Scientists have created a 3D-printed cartilage ear with an antenna that extends hearing far beyond the normal human range.
In general, there are mechanical and thermal challenges with interfacing electronic materials with biological materials," said Michael McAlpine, an assistant professor of mechanical and aerospace engineering at Princeton and the lead researcher. "Previously, researchers have suggested some strategies to tailor the electronics so that this merger is less awkward. That typically happens between a 2D sheet of electronics and a surface of the tissue. However, our work suggests a new approach — to build and grow the biology up with the electronics synergistically and in a 3D interwoven format."

4. Blog reader asks:
I recently came across "The solitary externally rotated foot", as well as the Cross Over Gait, and Applied Gait Hip Mechanics videos. First of all, your material very insightful, so thank you! I am an amateur runner that exhibits external foot rotation and cross over running, which I suspect causes my hip pain (where the GMed joins the femur) over long distances. Curiously, this pain completely disappears when running up hill. Is this an anomaly, or does the slope correct my gait somehow?

5. FACEBOOK readers asks:
  • HI: Can you tell us what role the gluteus medius plays in foot pronation. What if they are weak or tight? And how about the QL, too? Would a foot supinator have weakened QLs (they don't get to work much) and a foot overpronator have over-worked/loaded QLs (controlling spin)? And hey, if I toss in functional scoliosis in the lumbar region to this mix, well, what a tight mess I have, eh? Any insights on how to become unscrewed?

6. Karis
  • Hi there, I'm sure you get 100,000 messages so thank you for your time for reading this! Today I had a revelation that I have external tibial torsion. After much googling about my knees turning in quite a lot when my feet are straight I finally found it! Then I found your blog on Tumblr and read all about it and watched the videos. I just wondered if you had any advice on running, I am keen to start running but I didn't know whether to run with my feet sticking out as my natural position or anything else I should be doing? I also wondered if it can be corrected marginally by doing any strength exercises? Thank you for your help in advance! Karis

Some of the signs of overtraining may include an unexplained decrease in performance, changes in mood state, excessive fatigue, the need for additional sleep, frequent infections, continued muscle soreness and loss of training/competitive drive.

We have included an article that puts it into simple light for the athlete:

8. Toe walking in children
In most cases no etiology of toe walking is found. The medical literature considers it abnormal if it persists after 3 years of age. Idiopathic Toe Walking (ITW) is considered a diagnosis of exclusion and is employed only when all other possibilities have been eliminated with a meticulous clinical examination and various investigations. If any etiology is found, the treatment should be first non operative
The differential diagnosis in children who walk on their toes includes mild spastic diplegia, congenital short achilles,  and idiopathic toe walking (ITW).  A reduced ankle range of motion is just needs to find the source of the reduction.......meaning funcitonal,  ablative (structural). Reported treatments have included serial casting, Botulinum toxin type A or surgery to improve the ankle range of motion.  Is there an immediate impact of footwear, footwear with orthotics and whole body vibration on ITW to determine if any one intervention improves heel contact and spatial-temporal gait measures.
