Forefoot valgus wedge effect

The purpose for creating the definitions, Direct mechanical effect of foot orthoses and Central nervous system mediated effect of foot orthoses is that we will, for the first time, be delineating the two possible modes by which a foot orthosis creates their kinetic and kinematic effects on the human foot and lower extremity. Basically, if the kinematic or kinetic effects we see or measure with foot orthoses can not be explained by modelling the foot relative to the orthosis reaction forces created, then we must assume that these effects are CNS mediated. This seems quite basic, but to my knowledge, no one has ever defined the effects of foot orthoses like this.

I normally would be writing this as a Precision Intricast Newsletter or sending this off for a paper to JAPMA but, due to current other personal and academic projects, I didn't want to take the time. In addition, I thought that by having Drs. Fuller and Spooner do some "instant peer review" for me, I could then be able to distribute this information instantly to others, since I enjoy the immediate academic feedback while my thoughts are directed on a subject. Maybe someday I will publish this information.

My definitions should not make you take any longer to treat patients but they will hopefully make you consider that the gait changes and therapeutic effects that you see with foot orthoses may either be direct mechanical effects or CNS mediated effects. In the long run, Phil, understanding these definitions and their ramifications will make you a more efficient and effective clinician since you will better understand the possible mechanisms of action of one of the most important therapeutic modalities that you are utilizing on your patients.

Hope this answers your questions.

Fair points.
Thanks

If you want to increase the patient's stance phase pronation, this will do it!
