Summary

Upper Extremity Rotation Test is a new test the evaluates 90-90 position, which is one of the requirements for overhead throwing. The aim of the study was to evaluate the reliability of the Upper Extremity Rotation Test in overhead athletes and the relationship between the Closed Chain Upper Extremity Stability Test and the Upper Quarter Y Balance Test.

Detailed description

Upper Extremity Rotation Test is a new test the evaluates 90-90 position, which is one of the requirements for overhead throwing. The aim of the study was to evaluate the reliability of the Upper Extremity Rotation Test in overhead athletes and the relationship between the Closed Kinetic Chain Upper Extremity Stability Test and the Upper Quarter Y Balance Test. Upper Extremity Rotation Test was found to be reliable in overhead athletes. Upper Extremity Rotation Test showed high reliability in overhead atheletes. There was no correlation between the Upper Exremity Rotation Test and the Upper Quarter Y Balance Test. A moderate corelation was found between the Upper Extremity Rotation Test and Closed Kinetic Chain Upper Extremity Stability Test.

Conditions

• Upper Limb Asymmetry

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Upper Limb Rotation Test	The athlete is positioned with the shoulder, elbow lateral epicondyle, greater trochanter, and ankle lateral malleolus in contact with the wall. In the push-up position, the elbows are started at shoulder height with a 90° bend, and the feet are placed in a shoulder-width apart position. Athletes are instructed to perform a rotation of the shoulder and trunk by touching a vertically placed band on the wall for 15 seconds in the position of 90° abduction and 90° external rotation of the shoulder. The tested side is the upper extremity where the closed kinetic chain position is maintained.
DIAGNOSTIC_TEST	Closed Kinetic Chain Upper Extremity Stability Test	Athletes were placed in a push-up position with a distance of 91.44 centimeters (cm) (3 feet) between their hands for the test position. Subsequently, they were instructed to touch one hand to the other as quickly as possible. The total number of touches within a 15-second period was recorded. Modified push-up position was used for women, and regular push-up position for men during this time. Prior to the test, a familiarization trial consisting of 5 repetitions was performed. The test was then repeated 3 times, and the average of these repetitions was recorded as the score. Individuals were given a 45-second rest period between repetitions. The normalized score, representing the touch count per individual's height, was calculated. The power score was obtained by multiplying the touch count by 68% of the individual's body weight in kilograms.
DIAGNOSTIC_TEST	Upper Quarter Y Balance Test	The Upper Extremity Y Balance Test was created using three rulers placed on the ground in the medial, inferolateral, and superolateral directions. The rulers in the superolateral and inferolateral directions were positioned at a 90° angle to each other, while the ruler in the medial direction was placed at a 135° angle with respect to these two directions. In this test, both arms started in a push-up position with shoulder-width apart. The athlete was then instructed to touch, using their non-dominant hand, the maximum reachable point in the medial, inferolateral, and superolateral directions.
