Test-retest Correlation in Isokinetic Shoulder Testing

Clinique Saint Jean, France32 enrolled

Overview

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.

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

Outcomes

Primary Outcomes

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).

Time frame: 1hour

Secondary Outcomes

Data in healthy patients

Evaluation of the peak torque of each measurement in healthy patients, have a database.

Time frame: 1hour

Establishing the test's external validity

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

Time frame: 1hour
