About this study
Official title: Comparison of Ankle Isometric Strength and Proprioception Between 9-10-Year-Old Junior Ice Hockey Players and Age-Matched Controls
This observational cross-sectional study aims to profile ankle isometric strength and proprioception in 9-10-year-old junior ice hockey players and to compare these outcomes and limb symmetry indices with age-matched non-athlete children. Ankle isometric muscle strength is assessed using a handheld dynamometer, and ankle proprioception is evaluated using a digital inclinometer. Measurements are performed bilaterally for dominant and non-dominant limbs. Group comparisons and limb symmetry analyses are conducted to identify potential neuromuscular differences related to sports participation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Junior Ice Hockey Players | Children aged 9-10 years who participate in organized junior ice hockey training on a regular basis | |
| Non-Athlete Children | Age-matched children aged 9-10 years who do not participate in organized sports or structured athletic training. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Ankle Isometric Strength
Ankle isometric muscle strength of the dominant and non-dominant limbs measured using a hand-held dynamometer (Lafayette Manual Muscle Testing System). Peak force values are recorded for dorsiflexion, plantar flexion, inversion, and eversion.
Measured: Single assessment session
Secondary outcomes (1)
Ankle Proprioception
Ankle joint proprioception assessed bilaterally for the dominant and non-dominant limbs using a joint position sense test with a digital inclinometer. Proprioceptive accuracy is expressed as absolute error in degrees between the target and reproduced ankle joint position.
Measured: Single assessment session

Questions about this trial
What is this clinical trial studying?
An observational study of Ankle Joint Function and Ankle Proprioception, run by Emine Merve Ersever.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 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: opening soon, as of the sponsor's last update on 13 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
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?
This study is still under way. Results are not available in the source record yet.
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?
Ankle Isometric Strength (time frame: Single assessment session). 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 13 Jan 2026.
