Exercise Therapy for Femoroacetabular Impingement Syndrome (SWEaT)

December 18, 2023 updated by: Schulthess Klinik

The Effect of Patients' Characteristics on the Responsiveness to Exercise Therapy for the Management of Femoroacetabular Impingement Syndrome: a Multi-center, Single-group, Intervention Study

The aim of the clinical trial is to investigate the characteristics of patients, who respond vs. not respond to exercise therapy for the nonsurgical management of femoroacetabular impingement syndrome (FAIS).

Study Overview

Status

Status

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

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

Patients with a diagnosis of FAIS will be recruited from 2 clinical centers and will receive exercise therapy (study intervention). Exercise therapy is a semi-standardized intervention and will last 12 weeks (3 months). Hip pain, function and quality of life will be assessed using a patient-reported questionnaire at baseline, 3, 6 and 12 months' follow-up. Hip joint contact pressure will be evaluated using motion analysis and modelling at baseline, 3 and 12 months' follow-up. Hip morphology will be evaluated using imaging at baseline and hip surgery rate will be evaluated at 6 and 12 months' follow-up.

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 (Estimated)

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 50 years (Adult)

Accepts Healthy Volunteers

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: Exercise therapy
Exercise therapy consists of improving dynamic hip joint stability by means of hip-specific and functional lower limb strengthening, core stability and postural balance exercises.
Other: Exercise therapy
  • Education
  • Hip-specific strengthening exercises
  • Functional lower limb strengthening exercises
  • Core stability exercises
  • Postural balance exercises

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 hip pain, function and quality of life
Time Frame: Baseline to 6 months' follow-up
Hip pain, function and quality of life will be assessed using the International Hip Outcome Tool - 33 Items
Baseline to 6 months' follow-up

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.
