About this study

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)

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • to practice an overhead sport at least 5 hours a week

Exclusion criteria

  • no shoulder pain
  • no history of shoulder pain
  • no history of shoulder surgery
  • no scoliosis or lower limb lengths differences

Treatment and study plan

Realization of the Athletic Shoulder Test and the Modified Athletic Shoulder Test

Other

The participants will have to perform both tests two times, with a 7-10 days rest period between the two sessions

Primary outcomes

  1. Strength of anteflexors in "I" position

    Time frame: Change from baseline to 10 days

    The strength developped in the "I" position will be assessed with a force plateform and a handheld dynamometer

  2. Strength of anteflexors in "Y" position

    Time frame: Change from baseline to 10 days

    The strength developped in the "Y" position will be assessed with a force plateform and a handheld dynamometer

  3. Strength of anteflexors in "T" position

    Time frame: Change from baseline to 10 days

    The strength developped in "T" position will be assessed with a force plateform and a handheld dynamometer

  4. EMG activity of upper trapezius

    Time frame: during the first session

    EMG activity of upper trapezius will be measured with surface electrodes (Delsys Trigno)

  5. EMG activity of lower trapezius

    Time frame: during the first session

    EMG activity of lower trapezius will be measured with surface electrodes (Delsys Trigno)

  6. EMG activity of serratus anterior

    Time frame: during the first session

    EMG activity of serratus anterior will be measured with surface electrodes (Delsys Trigno)
