Influence of Gait and Running on Foot Posture

Influence of Gait and Running on Foot Posture Index and Navicular Drop Modifications for Non-athletes.

Objective: To evaluate in a sample of healthy non-athlete subjects, if the foot tends to a pronated position during a period of running compared to walking, evaluated during and after one hour after performing said activity.

Design: Quasi-experimental study, experimental and control group. Setting: Subjects who attend the Podiatry Clinical Area of the University of Seville.

Participants: N=72 healthy non-athlete volunteer adults who regularly run.

Study Overview

• Status: Recruiting
• Conditions: Foot Pronation in Healthy Adult
• Intervention / Treatment: Behavioral: foot posture index

Detailed Description

Interventions: The volunteers will participate in the research on three occasions, the day of data collection, one day when they will carry out a one-hour walking period and on another occasion where they will carry out an hour of running. Changes in foot posture [FPI] or foot pronation position (navicular drop [ND]) were identified in various periods of time at the time of the initial assessment and examination (p1), after 30 minutes of walking or running ( p2), 45 minutes of walking or running (p3) and 60 minutes of walking or running (p4) of the activity elapsed.

Main outcome measures: Foot position will be measured using the Foot Posture Index (FPI) and navicular height using the navicular drop test (ND) at p1, p2, p3 and p4.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
control; healthy adults than gait over 1 hour,	Behavioral: foot posture index; the tendency to foot pronation in healthy subjects will be compared during one hour of walking versus one hour of running in subjects who usually run.; Other Names: Navicular drop test
experimental; healthy adults that run over 1 hour	Behavioral: foot posture index; the tendency to foot pronation in healthy subjects will be compared during one hour of walking versus one hour of running in subjects who usually run.; Other Names: Navicular drop test

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Foot posture index	The FPI consists of 6 criteria obtained from the subject's foot where each of them gives a score from -2 to +12. Its use is simple and is scientifically validated. The subject must be in a comfortable standing position where they support their feet as they usually do naturally. Its realization lasts approximately 2 minutes maximum for each of the feet, and after its execution an independent total value is obtained for each one of them that indicates a pronated, supinated or normal posture that goes from -12 to +12 value. .	15 minutes
navicular drop test	to evaluate the difference between the original height of the navicular tuberosity in sitting position and in load corresponds to the drop of the scaphoids, therefore, to the descent of the internal longitudinal arch	15 minutes
