Turkish Version of the Ankle Instability Instrument

Study Overview
=================
Brief Summary
-----------------
This study aimed to translate the Ankle Instability Instrument into Turkish language, to perform a cultural adaptation study and to evaluate its validity and reliability in the Turkish population. Ankle Instability Instrument was developed to determine the ankle instability level of individuals with a history of ankle injury. Assessment of ankle instability is particularly useful in determining the complaints and functional levels of individuals with a history of functional or chronic ankle instability. It is anticipated that introducing this scale to our language will contribute to other studies in this field.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ankle Instability Instrument | The Ankle Instability Instrument includes 9 questions that can be answered with yes or no. The first version was developed with 21 questions and later modified into 9 questions. The Ankle Instability Instrument determines the development of functional ankle instability in individuals with an ankle injury. The International Ankle Consortium reported that answering yes to 5 of 9 questions will confirm the presence of functional ankle instability. There are French and Iran versions of the Ankle Instability Instrument. | 2 weeks | 
| Cumberland Ankle Instability Tool | The ankle instability levels of the participants included in the study will be determined by the Cumberland Ankle Instability Tool. The Cumberland Ankle Instability Tool is a self-assessment scale that determines the presence of functional or chronic ankle instability and the severity of the instability. This scale consists of 9 items and the total score varies between 0 and 30. Lower scores indicate more severe instability. | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Short Form 12 | Short Form 12 is a valid and reliable scale for determining the level of quality of life. This scale consists of 12 items and can be scored as 8 subscales. These subscales are; physical function, restricted roles due to physical problems, pain, general health, energy / vitality, social functions and mental health with restricted roles due to mental problems. All items are evaluated with a 5-point Likert-type scale, and higher scores indicate better quality of life while lower scores indicate poor quality of life. This scale is used to evaluate the quality of life of healthy individuals with any pathology. Short Form 12 can be scored between 0-100 for each domain. | 1 day |
