Effects of Gait Retraining With Auditory Feedback

August 16, 2024 updated by: Luke Donovan, University of North Carolina, Charlotte

Effects of Gait Retraining With Auditory Feedback on Biomechanics and Ankle Joint Health in Individuals With Chronic Ankle Instability

There is evidence to support individuals with chronic ankle instability (CAI) have altered gait biomechanics which may lead to re-injury and poor patient outcomes. Currently, there are no interventions specifically targeting these abnormal gait biomechanics. Evidence supports the use of an external focus of attention feedback to promote motor learning and retention. The overall purpose of randomized clinical trial is to determine the effects of a 2-week (8 session) gait retraining protocol using an auditory external feedback instrument can (1) alter biomechanics during functional tasks (walking, step-down, lunge, lateral hops, and balance) (2) improve ankle cartilage measures and (3) improve patient-reported outcome measures.

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.

Study Type

Study Type

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

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

18 years to 40 years (Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Auditory Feedback
Participants will complete 8 sessions over a 2-week period of walking gait retraining on a treadmill while receiving auditory feedback.
Other: Auditory Feedback
Participants will complete 8 sessions over a 2-week period of walking gait retraining on a treadmill while receiving no feedback. Participants will be instructed to walk on a treadmill at their desired pace in a manner that does not cause the auditory tool to elicit a noise.
Active Comparator: No Feedback
Participants will complete 8 sessions over a 2-week period of walking on a treadmill without receiving feedback.
Other: No Feedback
Participants will complete 8 sessions over a 2-week period of walking gait retraining on a treadmill while receiving no feedback. Participants will be instructed to walk on a treadmill at their desired pace in a manner that they perceive to be their normal walking speed and mechanics.

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
Changes from baseline in lower extremity kinetics during walking
Time Frame: Immediate post-intervention, 1-week post-intervention
Plantar pressure and center of pressure trajectory measured with an in-shoe plantar pressure system
Immediate post-intervention, 1-week post-intervention
Changes from baseline in talar cartilage deformation before and after walking
Time Frame: Immediate post-intervention, 1-week post-intervention
Talar cartilage thickness and cross-sectional area will be measured with an diagnostic ultrasound imaging system
Immediate post-intervention, 1-week post-intervention
Changes from baseline in self-reported ankle function
Time Frame: Immediate post-intervention, 1-week post-intervention
Changes from baseline in self-reported function as measured by the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living and Sport questionnaire. Scores range from 100% (no decrease in function) to 0% (complete loss of function).
Immediate post-intervention, 1-week post-intervention

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
Changes from baseline in static balance
Time Frame: Immediate post-intervention, 1-week post-intervention
Static balance will be measured via a force plate
Immediate post-intervention, 1-week post-intervention
2. Changes from baseline in plantar pressure during forward lunges, lateral hops, and a step-down
Time Frame: Immediate post-intervention, 1-week post-intervention
Plantar pressure during forward lunges, lateral hops, and a step-down will be recorded with an in-shoe insole system.
Immediate post-intervention, 1-week post-intervention
