Brief Summary

Background: To assess the impact of pre-season clinical measures and rotator muscles strength on the risk of significant shoulder injury (SSI) in elite adolescent badminton players Design: Prospective cohort study Participants: Nine elite adolescents badminton players were included and followed from September 2018 to May 2019. Independent variables: A pre-season visit consisted in clinical and isokinetic shoulder strength testing. Isokinetic internal and external rotator shoulder muscles strength was tested at 60, 120 and 240°/s. Conventional and functional (eccentric-to-concentric) ratios (FR) were calculated. SSI collection was performed by an experienced sport physician.

Conditions

Sport Injury; Shoulder Injuries

Outcome Measures

Primary Outcomes (7)

• Change from Baseline Isokinetic strength testing (peak torques) at 8 months

  Shoulder rotator muscles isokinetic strength test, Measures: Peak Torque on internal rotator muscles (IR) and external rotator muscles (ER), in NM (newton.meter)

  Two evaluations, one preseason (september 2018) and one postseason (may 2019) visits

• Change from Baseline Isokinetic strength testing (ratios) at 8 months

  Shoulder rotator muscles isokinetic strength test, Measures: ratios between external rotator muscles (ER) and internal rotator muscles (IR) (ER:IR), in percent (%)

  Two evaluations, one preseason (september 2018) and one postseason (may 2019) visits

• Clinical measurements, ROM

  Shoulder internal and external rotation range of motion (ROM)

  One evaluation, one preseason visit (september 2018)

• Clinical measurements TAD

  table-to-acromion distance (in cm)

  One evaluation, one preseason visit (september 2018)

• Significant Shoulder Injury (SSI) collection (number of injury)

  Significant Shoulder Injury (SSI) collection for the number of injury

  During the badminton season, the number (number, n) of injury was recorded from september 2018 to may 2019

• Significant Shoulder Injury (SSI) collection (type of injury)

  Significant Shoulder Injury (SSI) collection for the type of injury

  During the badminton season, the type of injury (number, n) was recorded from september 2018 to may 2019

• Significant Shoulder Injury (SSI) collection (time lost from participation)

  Significant Shoulder Injury (SSI) collection for time lost from participation due to the injury

  During the badminton season, the time lost from participation was recorded (in days) from september 2018 to may 2019

Study Arms (1)

Elite adolescent badminton players

The population was all the elite adolescent badminton players from a high-level club. We excluded players who had SSI in the 3 months prior to the isokinetic test or had shoulder surgery. They were included and followed from September 2018 to May 2019.

Eligibility Criteria

• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The population was all the elite adolescent badminton players from a high-level club

You may qualify if:

• All the elite adolescent badminton players from a high-level club.

You may not qualify if:

• Players who had SSI in the 3 months prior to the isokinetic test or had shoulder surgery
