So, when I watch someone walk and run, I look for over-supination at heel strike. I see if simply the shoe needs changing from stability to neutral. I teach the patient how to perform lateral power lacing. I evaluate any shoe inserts/orthotics to see if I can adjust for anti-supination. And, I may also wedge their midsole as shown in the photos below to see if this helps eliminate supination at heel strike, and ease their symptoms.
|Lateral (baby toe side) of the midsole is opened with a scalpel. This process can be easily done by some shoe repair stores.|
|In this case, a 1/4 inch wedge of grinding rubber from JMS Plastics is placed into the opening. Both sides of the midsole and both sides of the wedge are initially glued with Barge Cement and let to dry for 10 minutes.|
|All excess wedge material is cut and ground off and SuperGlue is used to seal any gaps that did not seal completely.|
So, when evaluating individuals with various injuries, watching them walk and/or run, can give you great clues to treatment. Gait evaluation should be done in most non-acute injuries to see if gait changes may help. This is one example of this process in action.
