Influence of Gait and Running on Foot Posture

December 12, 2025 updated by: Aurora Castro Mendez, University of Seville

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

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Foot posture index
Time Frame: 15 minutes

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
Time Frame: 15 minutes
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

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Foot posture index
Time Frame: 60 minutes

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. .

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
