Validation of Modified AST

Validity and Reliability of the Modified Athletic Shoulder Test

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.

Study Overview

• Status: Completed
• Conditions: Strength
• Intervention / Treatment: Other: Realization of the Athletic Shoulder Test and the Modified Athletic Shoulder Test

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)

• Study Type: Observational
• Enrollment (Actual): 20
