Clinical Trial Summary

The objective of the study is the validate and to assess the reliability of a modified version of the Athetic Shoulder Test. The activity of peri-scapular muscles during the realization of the test will be assessed too.

Description:

The study will be divided into two sessions. A time of 7-10 days will be provided between the two sessions of tests to limit the influence of sport and training on the results. Session 1: - Warm-up - Realization of the Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior) - Realization of the modified Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior) Session 2: - Warm-up - Realization of the Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior) - Realization of the modified Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior)
