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

Shoulder Muscle Imbalance as a Risk Factor for Shoulder Injury in Elite Adolescent Badminton Players: a Prospective Pilot Study

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.

Inclusion Criteria:

All the elite badminton players from a high-level club and the National Institute of Sport, Expertise, and Performance

Exclusion Criteria:

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