Orthopaedic Simulation of Morton's Extension to Test the Effect on Plantar Pressures of Each Metatarsal Head in Patients Without Deformity: A Pre-post-test Study.

Not Applicable

Completed

• Conditions: Healthy Subjects
• Interventions: Other: Morton extension

• Registration Number: NCT05879094
• Lead Sponsor: Mayuben Private Clinic

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.

Primary Outcome Measures

Name	Time	Method
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.
After 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.
