Brief Summary

In this study, it is aimed to evaluate different ankle functions and postural control variables in university level volleyball players and students with stable ankles and to examine the results obtained. In this way, we aim to contribute to the physiotherapy and rehabilitation literature and clinical studies of physiotherapists who are interested in athlete health. The hypothesis set in this study is: H0: There is no difference between ankle functions and postural control variables of volleyball players and healthy controls. H1: There is a difference between ankle functions and postural control variables of volleyball players and healthy controls.

Outcome Measures

Primary Outcomes (5)

• Postural control

  Postural control is evaluated according to the results of the static stability test performed on the PK Prokin 252 balance device with proven reliability. Postural control outcome is measured by the findings of the Prokin System, wich are: Average center of gravity on the X-axis (mm), Average Y-axis center of gravity (mm), Forward-backward standard deviation (mm), Medial-lateral standard deviation (mm) variables.

  Baseline

• Ankle Joint Range of Motion

  Range of motion assessment is made using a goniometer. Dorsiflexion and plantarflexion in the tibiotalar joint, and eversion and inversion in the subtalar joint is evaluated both actively and passivley. These evaluations will be repeated 3 times and their averages will be recorded.

  Baseline

• Ankle Joint Proprioception

  The assessment is made by a goniometer. First the referance degree is passively tought and then while eyes are closed, the person tries to reach the referance degree. The movements starts from 145 degrees of plantar flexion to the degrees of 105, 120, 130 and 140.

  Baseline

• Vibration Sense

  Vibration evaluation is made with the help of tuning fork (128 Hz). The eyes are closed throughout the application. Reference points are the big toe, fifth toe, and medial malleolus. The person is instructed to say when the feeling of vibration ends. A timer was used to count the time.

  Baseline

• Ankle Joint Muscle Strength

  The maximum isometric strength of the ankle is evaluated with the manual dynamometer measurement, the validity and reliability of which has been proven. JTECH Commander Powertrack Manual Dynamometer was used for measurements. Dorsiflexion, plantar flexion, eversion and inversion movements are assessed.

Study Population

The study was carried out with female individuals aged 18-25 who have stable ankles and have not had an ankle injury in the last 1 year. The study includes volleyball players playing in university teams and healthy university students who meet the same criteria.

You may qualify if:

• Female gender,
• Being between the ages of 18-25,
• Having a score of ≥24 on the Cumberland Ankle Instability Questionnaire,
• Volunteering for the study.

You may not qualify if:

• Presence of neuromuscular system disease,
• Presence of vestibular or visual problems,
• Presence of acute or chronic pain,
• An ankle injury in the last year,
• For the control group, regular participation in sports activities or physical activity for more than 150 minutes, 5 days a week.
