Shoulder Muscle Imbalance as a Risk Factor for Shoulder Injury in Elite Badminton Players

Completed

• Conditions: Shoulder Injuries; Sport Injury

• Registration Number: NCT04486807
• Lead Sponsor: University Hospital, Caen

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 badminton players Design: Prospective cohort study Participants: Nineteen elite adolescents badminton players were included and followed over the badminton season (from september 2018 to may 2019 and/or from september 2019 to may 2020) .

Independent variables: A pre-season visit consisted in clinical and isokinetic shoulder strength testing. Clinical testing consisted in the shoulder range of motion (ROM) measurements and the table-to-acromion distance (TAD)Isokinetic internal and external rotator shoulder muscles strength was tested at 60 and 240°/s. Conventional and functional (eccentric-to-concentric) ratios (FR) were calculated. SSI collection was performed by an experienced sport physician.

Primary Outcome Measures

Name	Time	Method
Clinical measurements TAD	one preseason visit (september 2018 or september 2019)	table-to-acromion distance (in cm)
Clinical measurements, ROM	ne evaluation, one preseason visit (september 2018 or september 2019)	Shoulder internal and external rotation range of motion (ROM)
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 or from september 2019 to may 2020	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 or from september 2019 to may 2020	Significant Shoulder Injury (SSI) collection for time lost from participation due to the injury
Baseline Isokinetic strength testing (ratios)	one preseason evaluation (september 2018 or september 2019)	Shoulder rotator muscles isokinetic strength test, Measures: ratios between external rotator muscles (ER) and internal rotator muscles (IR) (ER:IR), in percent (%)
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 or from september 2019 to may 2020	Significant Shoulder Injury (SSI) collection for the type of injury
Baseline Isokinetic strength testing (peak torques)	one preseason evaluation (september 2018 or september 2019)	Shoulder rotator muscles isokinetic strength test, Measures: Peak Torque on internal rotator muscles (IR) and external rotator muscles (ER), in NM (newton.meter)
