About this study
The objective of the study is to examine the reliability of the Upper Limb Rotation Test in adolescent male basketball players aged between 14 and 16. According to the sample size calculation for the study, 51 athletes were included. The Upper Limb Rotation Test was administered to the athletes twice, with a one-week interval. The athlete was positioned in a plank stance with shoulder, elbow lateral epicondyle, greater trochanter, and ankle lateral malleolus making contact with the wall. The athletes were instructed to perform a 90° abduction and 90° external rotation of the shoulder, accompanied by trunk rotation for a duration of 15 seconds. The number of repetitions was recorded. The tested side was the upper extremity in which the closed kinetic chain position was maintained. The test was repeated three times, and the average of the results was calculated. The Upper Extremity Rotation Test is a reliable assessment tool for evaluating performance in adolescent basketball players aged 14-16, particularly in relation to shooting skills.

The tested side was the upper extremity in which the closed kinetic chain position was maintained. The test was repeated three times, and the average of the results was calculated. The ICC (intraclass correlation coefficient) value, SEM (standard error of measurement), and MDC (minimal detectable change) values were calculated to assess the test-retest reliability of the evaluation tool. A low SEM value indicates higher reliability of measurements. The MDC value represents the smallest detectable change between two measurements. Differences below this value are considered practically undetectable or statistically insignificant.

What is being measured
The primary outcome is the main question the study is designed to answer.
The Reliability of the Upper Limb Rotation Test
The Upper Limb Rotation Test was administered to the athletes twice with a one-week interval between the tests. The athlete was positioned in a plank position with shoulder, elbow lateral epicondyle, greater trochanter, and ankle lateral malleolus touching the wall. The athletes were instructed to perform a 90° shoulder abduction and 90° external rotation, along with a body rotation, for a duration of 15 seconds. The number of repetitions was recorded. The tested side involves the upper extremity where a closed kinetic chain position is maintained. The test was repeated three times, and the average of the results was calculated.
Measured: through study completion, an average of 1 year

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The Reliability of the Upper Limb Rotation Test (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06269601, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
