About this study
Official title: Mobility, Strength, and Functional Outcomes Before Surgery, at 3 Months, and at 6 Months
The aim of this study is to identify the factors associated with successful rehabilitation following hip arthroscopy for femoroacetabular impingement syndrome and to highlight any persistent functional deficits at different key stages of rehabilitation. This is a controlled multi-observational study. The pathological hip of patients will be compared to their second healthy hip as well as to a healthy control group.
Assessments of mobility, strength, functional tests, and questionnaire submissions will take place before the intervention and 3 and 6 months after the intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Patient groups: 30 subjects with femoroacetabular impingement syndrome | Not described | |
| Control group : 30 subjects with healthy hips | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
Muscle strength in Nm
Muscular strength is measured using a fixed dynamometer
Measured: Pre-intervention, at 3 months and 6 months post-intervention
Hip mobility in degree
Hip mobility is measured using an electronic goniometer
Measured: Pre-intervention, at 3 months and 6 months post-intervention
Functional results on the Y Balance Test
The functional results of the Y balance test will be measured using the composite score.
Measured: Pre-intervention, at 3 months and 6 months post-intervention
Functional results in the single-leg squat test
The functional results of the single-leg squat test will be measured using the SIngle-leg squat Movement Performance scaLe for Individuals with FemoroAcetabular Impingement syndrome (SIMPLAI-FAI). The score on this scale ranges from 0 to 8. A higher score indicates a better functional outcome.
Measured: Pre-intervention, at 3 months and 6 months post-intervention
Measurements of patient-reported outcomes using the Hip-Return to Sport After Injury Scale (HIP-RSI)
Analysis of scores obtained on the HIP-RSI questionnaire. This questionnaire assesses psychological readiness to resume sports activities following hip surgery. It consists of six items, and the final score ranges from 0 to 100. A higher score indicates greater psychological readiness to return to sports activities.
Measured: Pre-intervention, at 3 months and 6 months post-intervention
Measurements of patient-reported outcomes using the International Hip Outcome Tool-12 (iHot-12) questionnaire
Analysis of scores obtained on the iHot-12 questionnaire. This questionnaire assesses the quality of life of young, active patients suffering from hip problems. It consists of 12 items and the final score ranges from 0 to 100. A score of 100 indicates full function and no symptoms, whereas a score of zero signifies maximum limitations and extreme symptoms.
Measured: Pre-intervention, at 3 months and 6 months post-intervention

Questions about this trial
What is this clinical trial studying?
An observational study of Femoroacetabular Impingement Syndrome and Healthy Participants, run by University of Liege at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 5 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Raphaël Leroy, PT, PhD candidate (+32491128430, rleroy@uliege.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle strength in Nm (time frame: Pre-intervention, at 3 months and 6 months post-intervention). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 May 2026.
