Reliability of Posterior Shoulder Endurance Test in Overhead Athletes

• Conditions: Healthy; Shoulder Pain
• Interventions: Diagnostic Test: Posterior Shoulder Endurance Test

• Registration Number: NCT04199988
• Lead Sponsor: Dokuz Eylul University

Brief Summary

The purpose of this study was to investigate the reliability of posterior shoulder endurance test in overhead athletes and to compare the endurance of posterior shoulder muscles between athletes with and without shoulder pain.

Detailed Description

A total of 40 overhead athletes, 20 with shoulder pain and 20 with no shoulder pain, will be included in the study. Shoulder endurance will be measured as isometric and isotonic on both arms of athletes using the posterior shoulder endurance test. The measurements will be repeated after 3-7 days, and the test-retest reliability of the isotonic and isometric posterior shoulder endurance test will be investigated.
