‘Gluten Brain’: Wheat Cuts Off Blood Flow To Frontal Cortex 


Influence of midsole hardness of standard cushioned shoes on running-related injury risk

Case From a blog reader
I’m a swedish elite cross-country skier and newly graduated physio and I find your podcasts very interesting and informative! I have a question about something I’ve never heard you talk about, and which has been a problem for me for the last year.
It’s about the IP-joint of the big toe. I’ve had discomfort/pain in the joint for the last year, mostly after my workouts. It’s a bit swollen and there is crepitus to some degree(especially when I manually flex the toe while compressing it and at the same time have a pressure downwards/ventrally of the distal phalanx. I think it may be coming from a trauma I had 4-5 years ago when I stubbed my big toe really hard in a rock in an orienteering competition, which caused me to rest from running for a week or two.
So, my question to you is if you have any suggestion for me or others in my situation? Treatment? Which types of shoes to use? How would a future joint-fusion affect my running?
I’m only 23 years old and I’m really worried that this ache/discomfort will just get worse and worse.. I’ve asked a lot of great physios here in Sweden, but most of them don’t know much about what to do.
I’d be really grateful if you could take the time to give this a thought and share it.
Another reader case:

Good morning. I am a former collegiate runner, I competed at Eastern Michigan University and Grand Valley State University, my father is a Chiropractor in northern Michigan. While in school I was recalled to active duty in the reserves after 9/11 and was unable to finish my eligibility. I am now 32, living in North Carolina, and trying to make a comeback to running and competing in Triathlons. At 6’2” and 170lbs. during college  I was competitive at the collegiate level  but always a step behind the true elites in the distance races in college, probably just because of my size, etc. competing against guys carrying 30 less lbs.

I train with a team called Without Limits  (iamwithoutlimits.com ) in Wilmington NC. My coach had mentioned that I had a really long loping stride which felt normal to me, but I cannot remember if I ran this way in college or not. When I finally counted, I had a cadence of 140 steps per minute rather then the optimal 180…

Long story short, I got really out of shape, now getting into pretty good form again, but I am having problems with the IT band and pain in the knee on the right leg. I never ever had this in college training at very high levels (90-100 mile weeks in the off and early parts of each season) …so now I have the bike component that I am working on, but being a larger distance runner I am trying to fine tune my gait/stride and see if I can improve my running that way and also figure out what is going on with this IT band issue as I am only running 30-40 miles/week now but on the bike and in the pool a lot. I am back down to 175 and pretty lean but carrying a little extra muscle from biking and swimming.

Would you be interested, if I could send you several high quality videos from different angles, in taking a look at my gait (or even riding the bike on the trainer) and see if you notice anything ? I have been working on improving my cadence since the IT band issues began, and found your videos online while doing research.  I understand this would be better done on a treadmill or in the parking lot at your office where you could watch up close, but if you are interested, please let me know. I look forward to hearing from you.

A 3rd case this week, on Dystonia

Do you guys have any recommendations for analysis and treatment of acquired focal and gait dystonia?
It started as a splinting mechanism with a very loose right si and some L5 radiculopathy over 5 years ago.  The dystonia would come and go then eventually stuck all the time.
All the dystonia is on the right side and I don’t have any systemic neurological disease.
Forward walking, stair climbing, running (although barefoot running in grass and in particular undulating surfaces is ok in small amounts, asphalt or treadmill
brings on dystonia within seconds) are all a problem. Can cycle, run in water for 40 minutes or so no problem, so I think Si may still be hypermobile.  Walking backwards no problem.
Dystonia presents as stiff right leg with knee hyperextension, right eccentric weak, right glute medius weak, sticky posterior weight shift, but full and
painless movement through complete range of hip and knee.  I do have some focal dystonia as well mostly knee extension with hip flexion and foot supination and eversion with hip and knee flexed.

There must be someone who deals with this somewhat locally to me, Virginia Beach, VA.  Hoping you all may have some contacts on the east coast.
