Chronic ankle instability was first defined by Freeman as recurrent ankle sprains following an ankle sprain and the feeling of dislocation in the ankle lasting longer than six months. The recurrence of ankle sprains in athletes leads to the realization of ankle instability. Functional ankle instability gives the feeling that a re-sprain will occur at any time due to decreased static and dynamic support in the joint.Neuro-vestibular-ocular exercises is an approach that combines neuromuscular training and vestibular-ocular training techniques.At the same time, we are doing this study because of the mixed studies on the effect of fascial relaxation on the performance and proprioception of a specific group of football players.
A total of 60 football players with instability \<27 according to the CAIT scale, whose proprioception and performance (jump, sprint, zig-zag test, kick speed) values were taken at the beginning, will be divided into two groups.Myofascial release will be applied to the lower extremity posterior line chain described by Myers by the physiotherapist to the first group.The other group (30 people) will be given neuro-vestibular-ocular exercises.Both groups will continue their training programme as ready.The training will be done in 2 sessions and 30 minutes per week.

CAIT Scale
Participants will be included based on the CAIT questionnaire and who get 27 points or less from this questionnaire. In the test, cut off score of less or equal to 27 as indicate of chronic ankle instability. The precision of the instrument is increased as it is a multiple answer option instrument. The CAIT is able to measure the severity of instability by using a numeric value and also can be filled out for both the left and right ankle, making it possible to assess both ankles individually.
Time frame: a day before the rehabilitation-at the time of discharge(8 weeks)
proprioception evaluation
The goniometer is used as a tool to measure proprioceptive perception of the ankle joint. Subjects are placed in the starting position with their eyes closed. The ankle subtalar joint is in neutral position (STJN) and the goniometer is set to zero. 20 degrees of inversion and 10 degrees of eversion are passively performed on the ankle and it is placed in neutral position.(13) The measurements are repeated 3 times and deviations from the target angle are measured with a goniometer.

Landing Error Scoring System (LESS)
Jumping performance will be measured by Landing Error Scoring System (LESS). Materials required for this;12 inch platform Target line (At a distance of half the subjects height)2 cameras at 1 meter height (At 10 feet in front of the landing area and at 10 feet to the right of the landing area)LESS scale.The athlete is instructed to jump forward from the box with both feet.Both feet should make contact beyond the target line.After contact, jump right back up to maximal height and land again on both feet.This is repeated for three trials.The video of the jumps is taken from both the cameras in front and at the side.The feet, ankle, knees, hip, trunk, shoulder, neck and head posture is assessed through the video.It is a 19-point continuous scale. According to the performance sheet, the questions 1-15 are Yes/No questions that are rated as 0 or 1. The questions 16 and 17 are rated as 0,1 and 2 depending on the joint displacement

30 meters Sprint Test
Sprint performance will be assessed by a 30-meter sprint test. A maximal 30 m sprint will be performed 3 times on the field. There is a 3-minute recovery period between the 30-m sprints. The shortest time taken to cover the 30 m distance in the sprint test will be taken into account.
Time frame: a day before the rehabilitation-at the time of discharge(8 weeks)
Zigzag agility test(with and without the ball)
There was a recovery time of 2 minutes between trials. The shortest time will be recorded as the performance of the zigzag agility tests with and without the ball. In the test, 4 cones are placed at the corners and 1 cone is placed in the center of the track. The long side of the track is 4,05 m (16 feet), the short side is 3 m (10 feet) (1feet=0,3 m)In the zigzag agility test with the ball, there is no specific rule such as the number of ball contacts. Time was measured using a stopwatch
Time frame: a day before the rehabilitation-at the time of discharge(8 weeks)
Kick Speed
The ball will be placed 11 meters away from the goal line. Cones will be placed 1 and 2 meters away from the starting position of the ball. The player will stand next to the cone at the 2nd meter and accelerate. Participants will be asked to kick the ball as fast as possible using the inside of the unstable foot. The measurement will be done with the apple app called "speed gun". The rest time between attempts will be 20 seconds. They will be told not to reduce the speed to improve the accuracy of the shot, the best time will be included in the trial results.
