Study summary

The aim is to determine whether the game of ice hockey has an effect on structural changes in the hip joint. The parameter to be investigated will be the increased frequency of structural changes of the hip joint in ice hockey players compared to a control group. Participants in the study will undergo MSK sonographic examination of both hip joints followed by functional hip mobility testing. The functional testing consists of three tests. Data will be processed in MS Office in MS Word, and the resulting data will be subject to statistical evaluation.

Read the detailed description

The examined hip joint structure will be examined monographically and simultaneously using functional tests, the Patrick test, a passive test of the range of motion in the hip joint to external and internal rotation in the joint, FADDIR test. Approximately 20 probands will be enrolled in the study based on voluntary participation from a group of players of the Charles University hockey team Prague, who have a valid medical examination with no restrictions on eligibility for selected sporting activities. The second group will consist of approximately 20 additional probands from the U20 age group of ice hockey players enrolled voluntarily with a valid medical examination with no restrictions on eligibility for the selected sporting activities. In addition, approximately 20 volunteers of the same age range will be included in the study and form the control group. In total, there will be approximately 60 participants in the study.

The conditions for inclusion in the first and second test groups will be an age range of 19-28 years, playing ice hockey for 6 years at least three times a week in the standard training regime of Czech ice hockey clubs. The player must be a registered player, i.e. his/her health condition must be suitable for ice hockey. The exclusion criteria for the test group will be persons outside the defined age limit with acute or chronic illnesses for any reason and persons with post-traumatic hip and pelvic conditions.

The inclusion criteria for the third control group will be the same age range of 19-28 years and no acute, especially infectious, diseases and persons with post-traumatic hip and pelvic conditions. This will be a normal recreational sporting population with no registration affiliation in any sport.

Study population

Twenty probands will be included in the study based on voluntary participation from the group of players of the university hockey team UK hockey Prague; the second group will consist of another 20 probands from the age group U20 ice hockey players included in the basis of voluntary participation, who have a valid medical examination without restrictions on eligibility for selected sports activities. In addition, approximately 20 volunteers of the same age range will be included in the study and form the control group. In total, there will be approximately 60 participants in the study.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 7, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
