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.

Design outcomes

Primary

Measure	Time frame	Description
Significant Shoulder Injury (SSI) collection (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 for the type of injury
Change from Baseline Isokinetic strength testing (peak torques) at 8 months	Two evaluations, one preseason (september 2018) and one postseason (may 2019) visits	Shoulder rotator muscles isokinetic strength test, Measures: Peak Torque on internal rotator muscles (IR) and external rotator muscles (ER), in NM (newton.meter)
Change from Baseline Isokinetic strength testing (ratios) at 8 months	Two evaluations, one preseason (september 2018) and one postseason (may 2019) visits	Shoulder rotator muscles isokinetic strength test, Measures: ratios between external rotator muscles (ER) and internal rotator muscles (IR) (ER:IR), in percent (%)
Clinical measurements, ROM	One evaluation, one preseason visit (september 2018)	Shoulder internal and external rotation range of motion (ROM)
Clinical measurements TAD	One evaluation, one preseason visit (september 2018)	table-to-acromion distance (in cm)
Significant Shoulder Injury (SSI) collection (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 for the number of injury
Significant Shoulder Injury (SSI) collection (time lost from participation)	During the badminton season, the time lost from participation was recorded (in days) from september 2018 to may 2019	Significant Shoulder Injury (SSI) collection for time lost from participation due to the injury
