Reliability of Posterior Shoulder Endurance Test in Overhead Athletes

Reliability of Posterior Shoulder Endurance Test in Overhead Athletes and Comparison of Athletes With and Without Shoulder Pain

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.

Study Overview

• Status: Recruiting
• Conditions: Healthy; Shoulder Pain
• Intervention / Treatment: Diagnostic test: Posterior Shoulder Endurance Test

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.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Athletes with shoulder pain; Overhead athletes with shoulder pain	Diagnostic test: Posterior Shoulder Endurance Test; Isometric posterior shoulder endurance test: In the prone position, the athlete's shoulder will be placed at horizontal abduction, and the time for maintaining this position will be recorded. Isotonic shoulder endurance test: In the prone position, the athlete's shoulder will be placed at horizontal abduction and asked to perform horizontal adduction-abduction, and the athlete will horizontally abducted-adducted his/her arm to 90 degrees at a cadence of 30 beats per minute. The number of repetitions will be recorded.
Athletes without shoulder pain; Overhead athletes without shoulder pain	Diagnostic test: Posterior Shoulder Endurance Test; Isometric posterior shoulder endurance test: In the prone position, the athlete's shoulder will be placed at horizontal abduction, and the time for maintaining this position will be recorded. Isotonic shoulder endurance test: In the prone position, the athlete's shoulder will be placed at horizontal abduction and asked to perform horizontal adduction-abduction, and the athlete will horizontally abducted-adducted his/her arm to 90 degrees at a cadence of 30 beats per minute. The number of repetitions will be recorded.
