Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to estimate the incidence and prevalence of Internal Rotation Deficit (IRD) defined by a measure of IRD 2 (Internal Rotation Deficit in position 2) strictly greater than 20 ° in a population of advanced-level handball players over a training season.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The secondary objectives of this study are :

A- To estimate and compare the prevalence of Internal Rotation Deficit within groups

B- To assess the association between the Internal Rotation Deficit and the appearance of a shoulder pain and/or discomfort when throwing

C- To assess the association between Internal Rotation Deficit and the appearance of a shoulder pathology demonstrated by clinical examination by at least one abnormality in one of the following three tests: the arming apprehension test, the relocation test or the O'Brien test

D- Assess changes in values of IRD 2, the ratio IRD 2/GRE 2, and the Total Range of Motion over the training season

E- Evaluate the association between the values of IRD 2 and the appearance of shoulder pain or discomfort when throwing

F- To evaluate the association between IRD 2 values and the appearance of a shoulder pathology (at least one anomaly in one of three tests: the arming apprehension test, the relocation test or the O'Brien test).

G- To assess the association between values of the IRD 2/GRE 2 ratio and the appearance of shoulder pain or discomfort when throwing

H- To assess the association between values of the IRD 2/GRE 2 ratio and the appearance of a shoulder pathology (at least one anomaly in one of three tests: the arming apprehension test, the relocation test or the O'Brien test).

I- To estimate the optimal threshold value of the IRD 2/GRE 2 ratio that would define an Internal Rotation Deficit in a more relevant fashion as compred to the IRD 2 alone
