Brief summary
The aim of this study is to simulate the orthopedic treatment called Morton's extension on non-deformed patients to check the effects on each metatarsal head on its static 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 effects on each metatarsal head on its static footprint, specifically the mean pressures and before and after the application of the morton extension.
Interventions
OTHERMorton extension
A Morton extension with a height of 5 mm was insert from the proximal area of the first metatarsal head to the base of the proximal phalanx of the Hallux of the subjects' bare feet using a paper bandage. The material, shape, size, and thickness of the Morton Extension were the same.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Before Morton Extension Medium pressure | Through 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. |
| Before Morton Extension Maximum pressure | Through 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). 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. |
