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.

Healthy Subjects

Keywords

metatarsalgia; foot; orthopedics

Outcome Measures

Primary Outcomes (4)

• 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.

  Through study completion, an average of 1 week

• Before Morton 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.

  Through study completion, an average of 1 week

• After Morton Extension Medium pressure

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.

Interventions

Morton extension OTHER

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.

You may qualify if:

• no history of trauma to the foot;
• the presence of at least 10° of dorsiflexion at the ankle with the knee fully dorsiflexed;
• unrestricted motion of the functional subtalar joint of 30°;
• unrestricted motion along the longitudinal axis of the midtarsal joint of 15°;
