Dear Biomech-l readers,

by pure curiosity, I have been wondering a bit about the history of
the use of the Center of Pressure when studying human gait and
posture. I'm not a researcher in biomechanics but in robotics, so I'm
not fluent in finding proper references in this field. The concept of
Center of Pressure seems to appear first in ballistics, and I've found
aerospace textbooks from the 1940s mentioning it although I'm
confident it's a far much older concept.

My guess is that this concept hasn't been introduced in biomechanics
until there was a way to measure it, perhaps not before the advent of
"modern" force platforms in the 1950s. I couldn't find however
references explicitly mentioning the center of pressure at that time.

The earliest I could find so far is:
AN INVESTIGATION OF THE CENTRES OF PRESSURE UNDER THE FOOT WHILE WALKING
By GRUNDY, BLACKBURN, TOSH, MCLEISH and SMIDT
In THE JOURNAL OF BONE AND JOINT SURGERY 1975

But I'm sure this can't be the first use of the center of pressure.

Could anybody point me at the definitive reference on this question?
Thanks a lot,
Pierre-Brice Wieber.
