About this study
A previous study of the Closed Kinetic Chain Upper Extremity Stability Test (EPOLTEST) in a population aged 18 to 25 years isolated 3 main factors influencing the CKCUEST score: upper extremity span, weight, and sex of the individual. A predictive equation for the CKCUEST score was thus established and to date has a capacity to determine the real score of approximately 51%.
The results of this first study show that a certain number of variables have not been studied.
The purpose of this study, EPOLTEST 2, is to take into account the variables already studied on a larger population (18-50 years old) and to add an assessment of shoulder muscle strength and abdominolumbar endurance.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Closed Kinetic Chain Upper Extremity Stability TestDiagnostic test
Each patient receive the same intervention, the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST). The CKCUEST is a functional test which assess shoulder's stability. Patient is in push-up position, with 91 cm between his hands. His body is straight and his foots are squeeze. patient has to touch his hand with his other one and returns in the initial position. Then, patient repeats this movement with his other hand, etc, during 15 secondes. The CKCUEST score is the movement's number performed.
Prone Bridge TestDiagnostic test
The prone bridge test also known as the "plank" or "hover" measures the muscular endurance of the abdominal muscles. Subjects will start in the "down" push up position with their feet together and their hands shoulder width apart. When the test starts the subject will push up to the prone bridge position so they are resting on their hands and toes making sure they maintain a straight line from the shoulders through the hips to the knees. The outcome measure will be the time where the subject stay in this position.
Measurement of the muscle strength of the shoulder complexDiagnostic test
Maximum isometric force of the external and internal rotators and abductors/adductors measured by a dynamometer.

Questions about this trial
What is this clinical trial studying?
A study testing Closed Kinetic Chain Upper Extremity Stability Test, Prone Bridge Test and Measurement of the muscle strength of the shoulder complex in people with Shoulder Pain, run by University Hospital, Brest at 1 site in France.
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 6 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: finished, as of the sponsor's last update on 10 Jun 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 France. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) score (time frame: Day 1). The study lists 10 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 10 Jun 2026.
