About this study
Official title: Evaluation of Test-retest Correlation in Isokinetic Shoulder Testing
This study is a prospective, monocentric interventional clinical study in 30 healthy volunteers.
The aim is to objectively assess shoulder external and internal rotation strength using a Cybex dynamometer in a specific position (seated with the arm at 45° abduction and 30° elevation).
The investigator would like here to determine the reproducibility of measurements in this precise evaluation position, but also to determine reference values in healthy subjects.
The results of this study will enable us to improve our management and establish a database for comparison with pathological subjects.

- Isokinetic
- Being tested
- external and internal shoulder rotation using a Cybex dynamometer
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
external and internal shoulder rotation using a Cybex dynamometerDevice
Measurement of the reproducibility, in this precise evaluation position, of the results obtained between the different tests carried out 30 minutes apart, and thus the reliability of each measurement in this test.
measures :
- Concentric internal rotation 60degrees/sec
- Concentric external rotation 60 degrees/sec
- Concentric internal rotation 180 degrees/sec
- Concentric external rotation 180 degrees/sec
- Eccentric internal rotation 60degrees/sec
- Eccentric external rotation 60degrees/sec

| External and internal shoulder rotation force | Experimental | shoulder external and internal rotation force objectively using a Cybex dynamometer in a specific position (seated with the arm at 45° abduction and 30° elevation) Receives: Device: external and internal shoulder rotation using a Cybex dynamometer |
What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation between each measurement at peak torque
Correlation between each measurement at peak torque below, and for each arm (12 correlations) in seated position abduction at 45 and 30 degrees anterior elevation.
- Concentric internal rotation 60degrees/sec
- Concentric external rotation 60 degrees/sec
- Concentric internal rotation 180 degrees/sec
- Concentric external rotation 180 degrees/sec
- Eccentric internal rotation 60degrees/sec
- Eccentric external rotation 60degrees/sec
Evaluation of results using an intraclass correlation coefficient (ICC).
Measured: 1hour
Secondary outcomes (2)
Data in healthy patients
Evaluation of the peak torque of each measurement in healthy patients, have a database.
Measured: 1hour
Establishing the test's external validity
Validated external test :
- External validity
- Differences between dominant arm / weak arm measurements
- Differences between eccentric and concentric measurements
- Difference between "test" and "retest" measurements
Measured: 1hour

Questions about this trial
What is this clinical trial studying?
A study testing external and internal shoulder rotation using a Cybex dynamometer in people with Isokinetic, run by Clinique Saint Jean, France 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 2 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: finished, as of the sponsor's last update on 15 Jun 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 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?
Correlation between each measurement at peak torque (time frame: 1hour). 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 15 Jun 2025.
