Strike index is the only one that I know of. I vaguely remember a relatively recent ACSM thematic poster with this info, but I'm not sure.

Jay Hertel has a couple of papers that have examined the range of COP.  We have also reported such data building upon the analysis that Jay developed.  I hope this helps.  Erik

Max:

I am curious to know  what you hypothesize will come out of this data, once compiled.

As an exert of foot typing and biomedical engineering of the lower extremity, I have some thoughts in this direction especially when it comes to selecting cohorts for biomechanical research and for developing treatment plans for metatarsalgia, foot orthotics, etc...

Dennis,

Absolute COP values are difficult to interpret. People with larger feet may have greater COP displacements simply because their feet are bigger. I was curious to see if anyone had used/seen a normalization method (i.e. to foot dimensions).

Max

I believe its not as simple as foot size, Max.

Differences between subjects (and even differences of the 2 feet of any one subject) including different vault heights, different rearfoot total ranges of motion and positional placement in closed chain, different forefoot total ranges of motion and positional placement in closed chain prevent "normalization".

Variability in CNS motor control of muscle engines predictability will not produce cohorts that can be "normalized".

Variability also exists in retesting the same feet at different times.

"Normalization" is also reduced when considering differences in intertester and intratester examiners,

to name a few other variables.

Yes I am aware, thank you. Typically, other factors are collected simultaneously (rearfoot eversion, ankle dorsiflexion, etc...). This current question is purely methodological.

Max

OK

Sorry if I diverted your topic.
