Prediction of Internal Risk Factors of Ankle Functional Instability in Gymnast Girls Aged 11-16 Years

The lower limb has been reported as the most common anatomical site for gymnastics injury, which mainly includes ankle sprains; Therefore, this study aimed to predict the internal risk factors of ankle functional instability in gymnast girls aged 11-16.

The current research was applied and descriptive. First, 35 female gymnasts aged 11-16 with ankle functional instability in jump-landing and landing skills and 35 healthy gymnasts were selected. The Cumberland Functional Instability Questionnaire was used to identify athletes with ankle functional instability. Dynamometer, goniometer and Y test were used to measure ankle strength, ankle range of motion and dynamic balance. SPSS23 software and logistic regression and Pearson correlation tests were used for data analysis.

The results showed that there is a significant relationship between ankle range of motion and muscle strength (inversion and eversion) and dynamic balance in different directions with ankle functional instability. However, there is no significant relationship between plantar flexion and dorsiflexion muscle strength with ankle functional instability.

it seems that among the internal factors of ankle instability injury, the variables of evertor muscle strength, range of motion of dorsiflexion and plantarflexion, and balance in the external posterior direction have a significant contribution in the regression model, and the four variables of the strength of evertor muscles, range of motion of dorsiflexion and plantarflexion, and the Y test In the posters-external direction, they can predict the occurrence of ankle functional instability.
