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

The aim of this study is to investigate the feasibility of a 12-weeks (progressive) exercise program in patients with FAIS. Feasibility is evaluated on the recruitment strategy, patient adherence to the exercises and their experiences with and motivation for performing exercises. Furthermore, the investigators wish to investigate the variation of data before and after the exercise program to help estimate a suitable sample size for a future randomized controlled trial.

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 50 years (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
Number of completed exercise sessions
Time Frame: 0-12 weeks
Number of completed exercise sessions. A high adherence is defined as attendance of > 75% of planned sessions
0-12 weeks
Completion of training program
Time Frame: 0-12 weeks
The training program is considered completed if patients are not dropping out of the study before the end of the 12 weeks. Completion rate will be calculated as % patients who completed the study
0-12 weeks

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

Time Frame: Change from 0-12 weeks
HAGOS is a questionnaire developed for young, active persons experiencing hip and/or groin pain. It consists of 6 subscales: Pain, Symptoms, Activities of Daily Living, Sport, Participation in Sport and Hip-related quality of life. The main subscales used in this study are HAGOS pain and sport.
Change from 0-12 weeks
The International Hip Outcome Tool (iHOT-33)
