This study was designed to assess the repeatability of the Emed(R)
ST2 system and identify the range of pressure values observed in the normal foot.
METHODS: Measurements were taken from twenty-three healthy subjects, 14 females
and 9 males, on two occasions
7 days apart. Begin of contact (BC), end of contact
(EC), contact time (CT), peak pressure (PP), instant of peak pressure (IPP),
contact area (CA) and pressure-time integral (PTI) were recorded. RESULTS : The
coefficient of repeatability (CR) was less than 16.0% for all 63 parameters
considered. In 87.3% of the parameters investigated (55 of 63) the CR (expressed
as a percentage of the mean) was less than 10%.
The highest areas of PP were
found under the great toe and second metatarsal heads, with mean (S.D.) equal to
435 kPa (202) and 407 kPa (146), respectively, followed by the third metatarsal
head 345 kPa (96) and the hindfoot 332 kPa (93).
The CT (% ROP (range of
pressure)) was in the range
74-85% under the metatarsal heads, and 71% under the
great toe. CA was highest under the heel at 33.8 cm(2). CONCLUSION: Emed(R) ST2
system was found to be repeatable. The presented range of parameters compared
very well to the results presented in the literature for the Emed(R) ST4 system.
