About this study
The study aims to explore the effect of body position (side-lying versus standing) on hip abductors muscle strength and activation in individuals with and without PFPS and then to compare these measures between the two groups in each position
Read the detailed description
A cross-sectional comparative study involving 44 subjects (22 subjects with PFPS and 22 healthy controls), aged 18-35 years. The study will measure hip abductor muscle strength (Peak torque, Maximal total work) using the Biodex Isokinetic System 4 PRO and muscle activity (%MVC) of the gluteus medius, gluteus maximus, and tensor fascia lata using Surface EMG (Noraxon Ultium EMG). Measurements will be taken in both standing and side-lying positions.

What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| PFPS Group | Subjects with unilateral PFPS diagnosed by an orthopedist; age 18-35 years; normal BMI | |
| Control Group | Healthy individuals without knee pain; age 18-35 years; normal BMI |
What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
An observational study of Patellofemoral Pain (PFPS), run by Ahram Canadian University at 1 site in Egypt.
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 1 inclusion and 1 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: opening soon, as of the sponsor's last update on 26 Dec 2025. 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 Egypt. 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 MOHAMED GOUDA MOHAMED, bachelor of physical therapy (+201092948701, mohamed.gouda@acu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle activity (%MVC) of the gluteus medius, gluteus maximus, and tensor fascia lata (time frame: During the assessment procedure (single time point)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07305610, which also lists 1 linked publication.
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 26 Dec 2025.
