Brief summary

The aim of this study is to simulate the orthopedic treatment called Morton's extension on non-deformed patients to check the different effects producted by sex in footprint.

Detailed description

The objective of this study is to perform an assimilation of the orthopedic treatment called morton extension on non-deformed patients to verify the difference effects due by sex on each metatarsal head and rearfoot on its static footprint, and plantar pressures variables in dynamic footprint.

MeasureTime frameDescription
Before Morton Extension Medium pressureThrough study completion, an average of 1 week.Static footprint will measure medium plantar pressures of first, second third fourth fifth and midfoot rearfoot and forefoot in Kilopascals (KPa). Subjects were instructed to stand barefoot on the force platform, participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline.
Extension Maximum pressureThrough study completion, an average of 1 week.Static footprint will measure maximum plantar pressures of first, second third fourth fifth and midfoot rearfoot and forefoot in Kilopascals (KPa).
