    Would someone bring the ol' man up to speed here. I am attempting to read what appears to be a 'bloody good article' and i'm already stumped in the opening paragraph. I am guessing the 'peak' refers to the displacement and the 'excursion' refers to the time?
    Is there an on-line biomechanical glossary I can access? I have found a few by googling but would appreciate a knowledgable pod's opinion.
    Thanks, mark c

    Hopefully somewhere in the small print the authors mention their definitions ...

    However, if its the William, McClay et al paper, then:
    Peak rearfoot eversion was the max rearfoot eversion in degrees past vertical(~pronation)
    Rearfoot eversion excursion was the total range in degrees of eversion from its most inverted position to it most everted position.

    Craig it is the William, Maclay Davis & ? paper.
    Enjoyed it immensely. One question, why does, in the conclusion, the authors mention the increased likelihood of damage to the knees lateral soft tissues but not the possiblity of compression stress? to the medial osseous structures from using (rearfoot) inverted orthoses? Thanks, mark c

    Not sure why they said that, as both can happen. It is a challenge facing the profession is the effect that foot orthoses used to treat foot pain may have on knee joint moments. I know you have see this thread on: Do foot orthoses increase the risk for medial knee OA? The challenge we are giving thought to is, is it possible to have a simple clinical (or complicated for that matter) test that we can use to go some way to predicting what the foot orthotic might be doing to the moments further up the chain....
