About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Elite badminton playersDiagnostic test
The population was all the elite badminton players followed in a University Hospital Centre and the National Institute of Sport, Expertise, and Performance. We excluded players who had SSI in the 3 months prior to the isokinetic test or had shoulder surgery.

Questions about this trial
What is this clinical trial studying?
An observational study of Sport Injury and Shoulder Injuries, run by University Hospital, Caen at 1 site in France.
The full registered description is in the About this study section and the official record.

Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Baseline Isokinetic strength testing (peak torques) (time frame: one preseason evaluation (september 2018 or september 2019)). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2020.
