Validation and Inverse Analysis of The Athletic Shoulder Test (ASH).
A study testing Athletic Shoulder (ASH) and Inverse Athletic Shoulder (IASH) Tests in people with Shoulder Pain and Sports Physical Therapy, run by University of Vigo at 1 site in Spain.
Trial summary
To validate both the Athletic Shoulder (ASH) test, conducted on rugby players, and its inverse, the Inverse Athletic Shoulder (IASH) test, for swimmers. This involves assessing the strength relationship between shoulder flexion and extension at three different adduction angles (180º, 135º, 90º) to identify potential… Read more about this study

About this study
Official title: Validation and Inverse Analysis of The Athletic Shoulder Test (ASH): Reliability of a Novel Upper Body Isometric Strength Test

This involves assessing the strength relationship between shoulder flexion and extension at three different adduction angles (180º, 135º, 90º) to identify potential injuries associated with these imbalances.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Athletic Shoulder (ASH) and Inverse Athletic Shoulder (IASH) TestsProcedure or surgery
Participants perform the Athletic Shoulder (ASH) test and Inverse Athletic Shoulder (IASH) test to measure maximal isometric shoulder strength in three positions (180º, 135º, 90º) during two separate sessions. Data is used to assess test reliability and validity for high-performance swimmers.

What is being measured
The primary outcome is the main question the study is designed to answer.
Intraclass Correlation Coefficient (ICC) for ASH Test
Assessment of between-day reliability of the ASH test using intraclass correlation coefficients (ICC) for shoulder extension at three adduction angles (180º, 135º, 90º).
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).
Intraclass Correlation Coefficient (ICC) for IASH Test
Assessment of between-day reliability of the IASH test using intraclass correlation coefficients (ICC) for shoulder flexion at three adduction angles (180º, 135º, 90º).
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).
Coefficient of Variation (CV) for ASH and IASH Tests
Analysis of the coefficient of variation (CV) to evaluate data dispersion and consistency for both ASH and IASH tests.
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).
Minimum Detectable Change (MDC) for ASH and IASH Tests
Calculation of the minimum detectable change (MDC) to identify the smallest significant change in performance beyond measurement error for both ASH and IASH tests.
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).
Force Ratios Between ASH and IASH Tests
Evaluation of the agonist-antagonist strength ratios between ASH (extension) and IASH (flexion) tests across three adduction angles (180º, 135º, 90º).
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).
Comparison of Shoulder Strength Between Preferred and Non-Preferred Breathing Sides
Analysis of differences in isometric shoulder strength between the preferred and non-preferred breathing sides in ASH and IASH tests across three adduction angles.
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).
Evaluation of Test Fatigue and Its Impact on Reliability
Assessment of fatigue effects during ASH and IASH tests, considering the 20-second rest period and total number of efforts (36 per participant), and their potential impact on test reliability and strength measurements.
Measured: Measured at two time points: baseline (Day 0) and follow-up (Day 2).

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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Intraclass Correlation Coefficient (ICC) for ASH Test (time frame: Measured at two time points: baseline (Day 0) and follow-up (Day 2).). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
