Has anyone any idea if studies have been done to determine what percentage of the uk population have gross over pronation at the STJ?

Thanks

What is gross over pronation ?

Do you mean extended periods of a proned foot during late propusion, or fixed pes valgus? If it is the lattewr you may get some data from studies relating to rheumatoid disease.

Hi Cameron

"Do you mean extended periods of a proned foot during late propusion"

Kind of. In particular the foot that is very marked in eversion through out the stance period. But no rheumatic.

Thanks
Ian

Don't really know of any studies of dynamic rearfoot motion that have looked directly at prevelance in populations. You could look at:

Staheli, L.T., Chew, D.E., Corbett, M.: The longitudinal arch. J Bone and Joint Surg. 1987, 69A: 426-428

Although this is not UK population.

Best wishes,
Simon

Thanks Simon, I will try to look it up.

You won't find any truly representative data on the prevalence of dynamic "overpronation at the STJ". No large-scale epidemiological studies have looked at this.

However, the Cheshire Foot Pain and Disability Survey (link) reported the following prevalence of self-reported flat feet:



...and the Feet First study of 784 people aged over 65 in the US (link) reported an overall prevalence of flat feet of 19%. Their definition of a flat foot was one in which "the examiner was unable to insert his/her fingers under the arch of the foot with the respondent in a standing position".

Thanks Hylton, very helpful.
