Test-retest Correlation in Isokinetic Shoulder Testing (ISO2024)

June 11, 2025 updated by: Clinique Saint Jean, France

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: External and internal shoulder rotation force
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)
Device: external and internal shoulder rotation using a Cybex dynamometer

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure

  • 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).

Establishing the test's external validity
Time Frame: 1hour

Validated external test :

1) External validity

  • Differences between dominant arm / weak arm measurements
  • Differences between eccentric and concentric measurements
  • Difference between "test" and "retest" measurements
