Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The four main parameters to be evaluated in the study are as follows:
* Ankle muscle strength (4 directions in concentric and eccentric modes)
* Joint range of motion (ROM)
* Static balance
* Dynamic balance Strength measurements will be assessed using an isokinetic dynamometer (Isomed 2000), joint range of motion using a goniometer, dynamic balance using the Y Balance Test (YBT), and static balance using the Diers Formetric 4D pedobarographic balance system. Strength measurements will be performed at angular velocities of 30°/s and 120°/s for plantar flexion and dorsiflexion and 60°/s and 90°/s for inversion and eversion in both the dancer and control groups.
The primary objective of the study is to determine the relationship between a history of ankle injury and these intrinsic parameters. It also aims to compare the control group with ballet dancers who have not suffered an ankle injury in the last year in terms of these intrinsic parameters.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ballet dancers without ankle injury
Ankle muscle isokinetic strength, joint range of motion, and dynamic and static balance will be measured in ballet dancers who have not taken a break from dancing in the last 12 months.
No interventions assigned to this group
Ballet dancers with ankle injury
The isokinetic strength of the ankle muscles, joint range of motion, and dynamic and static balance of ballet dancers who have taken at least a week off from dancing due to an ankle injury within the last 12 months will be measured.
No interventions assigned to this group
Control
The ankle isokinetic muscle strength, joint range of motion, dynamic and static balance of healthy male and female volunteers over the age of 18 without ankle injuries will be measured.
No interventions assigned to this group
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria

* For the Control Group:

4. Reside in the province of İzmir
5. Agree to participate voluntarily and have signed an informed consent form
Exclusion Criteria
