Frontal plane compensation?

    Hello.

    I am 3rd year Pod. student.

    I have one question about frontal plane compensation of subtalar joint.

    Does this concept mean that the subtalar joint axis lies closer to horizontal/sagittal plane, thus more frontal plane motion(inversion/eversion) available(plane dominance), resulting the foot more pronated?

    I referred to the Article, 'Plane dominance' (Green & Carol, 1984), but still get confused..

    Can anyone clarify this frontal plane compensation concept, especially why "compensation"?

    Thanks

    Hi,

    The compensation is because the reference point for planal dominance is the foot against a hard, flat surface - similar to the surface we live on most of the time in the West.

    Given that our feet were not built for hard.flat surfaces only, but a multitude of surfaces it is easy to see why you find the article confusing. Planal dominance would not, for instance, have much relevance if the subject walked on soft ground, or uneven ground - where each footfall is different.

    The article you cite is important, but it's also over 25 years old too - there have been updates on the planal dominance theory since then.

    You are correct about the axis lying more horizontally BTW.
