Hip InjuriesNCT01821183
Strength and Strength-ratio of Hip Rotator Muscles at Soccer Players
An observational study of Hip Injuries and Muscular Atrophy, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.
Trial summary
At this investigation we want to find out whether there is a difference in muscle strength of the internal and external rotation hip muscles between soccer players and non-soccer players caused by typical movement patterns seen in soccer sport. Read more about this study

About this study
Official title: Strength and Strength-ratio of Hip Rotator Muscles at Soccer Players Compared to Non-soccer Players
At this investigation we want to find out whether there is a difference in muscle strength of the internal and external rotation hip muscles between soccer players and non-soccer players caused by typical movement patterns seen in soccer sport.
Read the detailed description
Nontraumatic hip injuries are a problem often seen in Soccer Players. A biomechanical formation mechanism is probably. Little research has focused on the measurement of hip external and internal rotation strength at soccer players. The purpose of this study is to investigate the influence of soccer sports at the isometric force and force ratio of the hip rotator muscle system. Two samples of Athletes will be compared: Soccer Players (N15) and Non-soccer players (N15) matched in sex, age and level of physical activity to investigate hip rotator force in 3 different angles of hip flexion (0°/45°/90°). The measurement will be made with a handheld dynamometer.

Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. 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?
Strength of the internal and external rotators of the hip (time frame: "up to 10 months"). 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 7 Aug 2013.
