Mobilizing the Big Toe
by Carson Boddicker on Apr 7th, 2010
For those who have ever seen the movie(s) Kill Bill, you may remember the incredibly comedic remark of “wiggle your big toe” after she had escaped from the hospital and was supine in a car. At the time I thought it was ridiculous but she may have been onto something. Clearly proper motion of the hallux is a valuable, even essential piece of efficient locomotion so how does one go about identifying and correcting limitations in first MTP joi...

The Big Toe and Windlass Mechanism
by Carson Boddicker on Apr 5th, 2010
While it is not a big joint, the first metatarsophalangeal joint may be one of the most important joints in running gait. There is no question that dysfunctional patterns can result from too much or not enough movement at any joint, however, when the metatarsophalangeal joint does not play, a great deal of compensations can result. As I noted in a previous post, proper gait requires the ability to flex the knee to 40 degrees, the dorsiflex t...

Normal Gait Mechanics
by Carson Boddicker on Mar 30th, 2010
For optimal function and resistance to injury and to better understand exactly what it is you are trying to accomplish with training, it is first important to understand the mechanics of a healthy foot and ankle complex before we begin to discuss dysfunctional patterns and how to approach their management. At foot-strike the healthy foot contacts the ground on the lateral aspect of the foot in a slightly supinated position with the majority of...

Running Economy and Barefoot vs. Shod Footstrike
by Carson Boddicker on Mar 25th, 2010
In yesterday's post we discussed briefly the three general foot strike patterns. If you recall, the habitually barefoot athlete most frequently strikes the ground with a FFS or MFS, whereas the shod runner most often makes contact ahead of his center of mass with a RFS. This differentiation is critical for a number of reasons, and particularly energy return and increased economy. It seems that prior to foot strike, the barefoot athlete "pr...

Barefoot Running vs. Shod Running
by Carson Boddicker on Mar 24th, 2010
Barefoot running has become an increasingly popular in the past several years as more and more examples find themselves falling into the popular media. So what is the deal? Is there any credence to the craze? Yesterday we gained an elementary knowledge of the foot and ankle's anatomy. Today, you'll take home a comparison of mechanics in barefoot subjects and those who wear shoes. Before we begin, it would be prudent to define a few th...
