A retrospective study was conducted in order to investigate the relation be
tween increased plantar pressure and ulcers in the diabetic foot and contri
bute more information on this subject. Maximal plantar pressure (MPP) is re
ported on various areas of the plantar aspects of the feet in 328 diabetic
patients and 75 healthy subjects. An increase in MPP under all plantar area
s except for the heels was found to be related with increasing severity of
the diabetes symptoms. There was also a significant decrease in the applica
tion of high pressures to the heels, the metatarsal heads II-IV and the toe
s.
