Brief Summary

The aim of this study is to investigate the effect of neuromuscular training on balance by using stroboscopic glasses in athletes with chronic ankle instability.

Conditions

Ankle Injuries

Keywords

balance; chronic ankle instability; function; running

Outcome Measures

Primary Outcomes (6)

• FAAM (Foot and Ankle Ability Measure),

  Pre-test evaluation will be done. After the end of neuromuscular training for 6 weeks, the final test will be evaluated. This value will be saved as %.

  8 weeks

• Ankle ROM

  The two bars of Optojump are placed on the treadmill with a speed of 3.5m / sec and the foot strokes, imbalance and heel strokes will be recorded and the normal joint movements of the ankle with the Myo-motion device will be recorded.

  2 weeks

• Balance

  Static and dynamic balances of athletes before and after neuromuscular training will be evaluated. Center of pressure area (COP) foot pressure point shall be evaluated in mm. And İt is defined as a measure indicative of the time and/or distance a subject spent away from a central point.

  2 weeks

• EEG (Electroencephalography)

  The theta and beta waveform of EEG values of people will be measured during the static and dynamic balance evaluation.

  2 weeks

• FAAM-S (Foot and Ankle Ability Measure Sport Scale)

  Pre-test evaluation will be done. After the end of neuromuscular training for 6 weeks, the final test will be evaluated. The Sports subscale is scored the same as FAAM (Foot and Ankle Ability Measure) 4 being 'no difficulty at all' to 0 being 'unable to do'. The score on each item are added together to get the item score total. The number of items with a response is multiplied by 4 to get the highest potential score. If the subject answers all 8 items the highest potential score is 32, if one item is not answered the highest potential score is 28, if two are not answered the highest potential score is 24, etc. The item score total is divided by the highest potential score. This value is multiplied by 100 to get a percentage. A higher score represents a higher level of physical function.

  8 weeks

• BMI (Body Mass Index)

  Body mass index will be calculated before neuromuscular training. It will be evaluated in kg/m2.

  2 weeks

Study Arms (3)

Training Group

EXPERIMENTAL

Neuromuscular training will be performed in this group for 6 weeks.

Other: Neuromuscular Training

Strobe Group

EXPERIMENTAL

This group will perform neuromuscular training for 6 weeks with a strobe glasses.

Other: Neuromuscular Training; Other: Strobe Glasses

Control Group

NO INTERVENTION

This group will not perform any neuromuscular training program.

Interventions

Neuromuscular Training OTHER

The experimental group will perform neuromuscular exercise for 6 weeks. The other experimental group will perform neuromuscular exercises with strobe glasses.

Strobe Group; Training Group

Strobe Glasses OTHER

Stroboscopic glasses, which is characterized by intermittent vision obstruction, is a clinical tool that allows clinicians to examine sensory feedback in a progressive manner without fully seeing visual information.
