Study Overview

Status

Status

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

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

This is a randomized, repeated measures, matched group study. There will be three groups of participants, 20 participants per group, 60 participants total. Group one (G1) will receive custom-fabricated bilateral braces and a standardized home walking/exercise program. Group two (G2) will receive an off-the shelf ankle support and standardized home walking/exercise program. Group three (G3) will receive the standardized walking/exercise program without any brace or AFO. Subjects will be randomized upon enrollment in the study. Subjects will be followed for one year during this study and outcome measures will be collected 3 times over the course of the study. Subjects will be seen every 6 months for the duration of the study for testing as well as for other visits as noted in the table below.

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

30 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Change in Distance Walked on 6-Minute Walk Test (6MWT)
Time Frame: 6MWT will be done at initial testing and 12 months
Each participant walks at a self-selected velocity on level surfaces for 6 minutes. They will be allowed to use assistive devices if necessary.
6MWT will be done at initial testing and 12 months

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
Change in Temporal Spatial Gait Parameters Using the Computerized Gait Analysis System
Time Frame: Testing will be done at initial testing and 12 months
Participants will be asked to walk on a 12-16 foot long vinyl pad placed on the floor. The mat will record and analyze temporal and spatial parameters.
Testing will be done at initial testing and 12 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Daily Activity as Measured by Steps Per Day
Time Frame: Total steps per day will be measured at the start of the study and a week prior to testing at 6 months, and 12 months
Participants will be asked to wear a pedometer for 7 days at designated times in study. Total steps per day will be recorded.
Total steps per day will be measured at the start of the study and a week prior to testing at 6 months, and 12 months
