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.

Condition or disease Intervention/treatment Phase
Ankle Injuries Other: Neuromuscular Training Other: Strobe Glasses Not Applicable

Detailed Description:

Lateral ankle sprain (LAB) is one of the most common musculoskeletal injuries of 15% of all injuries reported in all sports.Chronic ankle instability (CAI) is characterized by life-long persistent symptoms in 40% of people with recurrent LAB sprain.

It has been reported that there is a change in sensorimotor function in the activity of individuals with CAI, and they are more dependent on visual information in balance parameters on one leg.While the somatosensory input was clinically feasible; The obstruction of the visual input has been limited in two ways, the eyes being fully open or fully enclosed.However, this changing dynamic has provided a means for the prevention of visual input during more sporty maneuvers, to directly reach compensatory neuroplastic sequelae after injury and to function in a functional way to train the neuromuscular system.This technological innovation makes this possible by reducing the visual input without completely eliminating it.This innovation, called stroboscopic goggles technology, provides a mechanism to disrupt to any degree between eyes closed and open in the visual system.

Stroboscopic vision, characterized by intermittent vision obstruction, can be a clinical tool that allows clinicians to study sensory feedback in a progressive manner without fully seeing visual information. So use stroboscopic goggles to prevent visual information, you can improve the functionality by emphasizing the somatosensor information.In particular, visual manipulations can significantly influence the healthy adult electrocortical dynamics and balance control by triggering the contradiction between visual adult, vestibular and proprioceptive inputs.

The aim of this study, which was planned for this purpose, will be to evaluate the effects of neuromuscular exercises performed on stroboscopic environment on equilibrium, neural feedback and running mechanics.

Arm Intervention/treatment
Experimental: Training Group
Neuromuscular training will be performed in this group for 6 weeks.
Other: Neuromuscular Training

The experimental group will perform neuromuscular exercise for 6 weeks.

The other experimental group will perform neuromuscular exercises with strobe glasses.


Experimental: Strobe Group
This group will perform neuromuscular training for 6 weeks with a strobe glasses.
Other: Neuromuscular Training

The experimental group will perform neuromuscular exercise for 6 weeks.

The other experimental group will perform neuromuscular exercises with strobe glasses.


Other: Strobe Glasses
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.

No Intervention: Control Group
This group will not perform any neuromuscular training program.



Primary Outcome Measures :
  1. FAAM (Foot and Ankle Ability Measure), [ Time Frame: 8 weeks ]
    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 %.

  2. Ankle ROM [ Time Frame: 2 weeks ]
    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.

  3. Balance [ Time Frame: 2 weeks ]
    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.

  4. EEG (Electroencephalography) [ Time Frame: 2 weeks ]
    The theta and beta waveform of EEG values of people will be measured during the static and dynamic balance evaluation.

  5. FAAM-S (Foot and Ankle Ability Measure Sport Scale) [ Time Frame: 8 weeks ]
    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.

  6. BMI (Body Mass Index) [ Time Frame: 2 weeks ]
    Body mass index will be calculated before neuromuscular training. It will be evaluated in kg/m2.
