Comparison Interventions on Kinetic and Kinematic Parameters
A study testing Manual therapy and Exercise in people with Young Football Players and Ankle Sprain Prevention, run by Medical University of Gdansk at 1 site in Poland.
Trial summary
Currently, it is difficult to find studies in the literature comparing proprioception exercises with the effect of manual therapy on improving balance, and in the long run it may translate into improved activity, functionality and injury prevention in athletes, when planning training or therapy, e.g. Read more about this study

About this study
Official title: Comparison of Selected Physiotherapeutic Interventions on Kinetic and Kinematic Parameters in Young Soccer Players
Currently, it is difficult to find studies in the literature comparing proprioception exercises with the effect of manual therapy on improving balance, and in the long run it may translate into improved activity, functionality and injury prevention in athletes, when planning training or therapy, e.g. in patients after ankle sprains.
- Conditions
- Young Football Players, Ankle Sprain Prevention
- Being tested
- Manual therapy, Placebo, Exercise
- Keywords
- soccer, proprioception, manualn therapy, postural balance, biomechanics
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Manual therapyOther
This technique involves mobilizing the upper ankle joints by mobilizing the talus and calcaneus, improving pronation.
PlaceboOther
The players will perform their own type of pro-receptive training.
ExerciseOther
Pro-receptive training will be performed.
| Study group | Role | What they receive |
|---|---|---|
| Group A "Diagonal Mobilization' | Experimental | Will be used: manipulation, placebo and exercise Receives: Other: Manual therapy; Other: Placebo; Other: Exercise |
| Group B "Placebo" | Placebo comparator | Will be used: manipulation, placebo and exercise Receives: Other: Manual therapy; Other: Placebo; Other: Exercise |
| Group C "Proprioception Training" | Active comparator | Will be used: manipulation, placebo and exercise Receives: Other: Manual therapy; Other: Placebo; Other: Exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Y balance test
Consists of the volunteer standing on one leg while simultaneously stretching the other lower limb in 3 different directions. These are: anterior, posteromedial and posterolateral.
Measured: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.
1. Balance
K-FORCE plates assess balance characteristics during testing.
Measured: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.
Secondary outcomes (2)
Assessment of proprioception.
The proprioception assessment involves assessing the angular position of the joint and then attempting to reproduce it, measured in degrees. The assessment will be conducted at 30 degrees, 60 degrees, and 90 degrees.
Measured: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.
Muscle strength assessment
The K-FORCE Push Test allows you to assess your strength characteristics during the hip abduction test.
Measured: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.

Where is the study taking place?
The record lists 1 site in Poland. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?
Y balance test (time frame: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.). The study lists 2 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.
