Sex Differences in Morton's Extension Application on Plantar Pressure Distribution in Different Foot Regions in Female and Male Patients Without Deformities: A Pre-Post Test Study

Mayuben Private Clinic50 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Before Morton Extension Medium pressure

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.

Time frame: Through study completion, an average of 1 week.

Extension Maximum pressure

Static footprint will measure maximum 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.

Time frame: Through study completion, an average of 1 week.

After Morton Extension Medium pressure

Time frame: Through study completion, an average of 1 week.
