There seems to be some controversy with regards to gait retraining. Some folks seem to believe that it should be “left to itself” and they are fully compensated already (1). Perhaps this is true…or not. We have not seen any studies that compare gait retraining vs non gait retraining as a whole, but there seems to be plenty for specific conditions (2). We all see folks AFTER THE FACT and seek to correct the problems and reverse, halt or slow the progression of further pathology. That seems to be what many of us do.

This recent study (3) looks ate altered loads and muscle recruitment patterns in patients with osteoarthritis. they conclude:

“This study documents alterations in hip kinematics and kinetics resulting in decreased hip loading in patients with hip OA. The results suggested that patients altered their gait to increase medio-lateral stability, thereby decreasing demand on the hip abductors. These findings support discharge of abductor muscles that may bear clinical relevance of tailored rehabilitation targeting hip abductor muscles strengthening and gait retraining.”

There is substantial evidence that hip pathomechanics lead to osteoarthritis (4, 5). Wouldn’t it make sense to assist in altering motor patterns and correct those biomechanical faults before it becomes a problem? Lets change our focus (if we haven’t already) and concentrate on skill, endurance and strength, in that order for the betterment of ourselves, our patients and humanity.

People who are injured move differently

Like we have said before, often times when folks are injured they often lose cortical function (afferent input) from a particular area, and their gait becomes more primitive, often taking a broader base, slower movement, increased amplitude of movement and sometimes requiring assistance or something to help them balance, like our post here

"Findings suggest that movement variability in those with a musculo-skeletal injury differs from uninjured individuals. Interestingly, there was an overall trend toward greater movement variability being associated with the injured groups, although it should be noted that this trend was not consistent across all subcategories (eg, injury type).

Notice the differences in running (top) vs sprinting (bottom) activation patterns?

This picture (along with the MIchaud muscular firing pattern ones) are becoming some of my favorite ones to talk about. I just stare at them and look for differences and similarities. 

Check out that the abs do not seem to fire in running (in this study at least), but do in sprinting. Note also that most muscles fire longer (and we wil assume harder) during sprinting. Also check out the peroneals, which fire just as the foot touches down in sprinting, probably to make up for the instrinsics not firing, and assist in creating a rigid lever for push off.

4.Do you know the difference between a forefoot supinatus and a forefoot varus?
"A forefoot varus differs from forefoot supinatus in that a forefoot varus is a congenital osseous deformity that induces subtalar joint pronation, whereas forefoot supinatus is acquired and develops because of subtalar joint pronation. ”
