Validation of Modified AST

Completed

• Conditions: Strength

• Registration Number: NCT05146115
• Lead Sponsor: University of Liege

Brief 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.

Detailed 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)

Primary Outcome Measures

Name	Time	Method
EMG activity of upper trapezius	during the first session	EMG activity of upper trapezius will be measured with surface electrodes (Delsys Trigno)
EMG activity of lower trapezius	during the first session	EMG activity of lower trapezius will be measured with surface electrodes (Delsys Trigno)
Strength of anteflexors in "I" position	Change from baseline to 10 days	The strength developped in the "I" position will be assessed with a force plateform and a handheld dynamometer
Strength of anteflexors in "Y" position	Change from baseline to 10 days	The strength developped in the "Y" position will be assessed with a force plateform and a handheld dynamometer
Strength of anteflexors in "T" position	Change from baseline to 10 days	The strength developped in "T" position will be assessed with a force plateform and a handheld dynamometer
EMG activity of serratus anterior	during the first session	EMG activity of serratus anterior will be measured with surface electrodes (Delsys Trigno)
