Study of relationship hetween previous ankle sprains and functionalperformance deficits in athletes

Despite of the importance of functional-performance deficits, little research addressed them in athletes with previous ankle sprains. The aim of this work was the study of relationship between previous ankle sprains and functional-performance deficits in athletes. The subjects of research were 40 professional athletes gathering through an accidental sampling among volunteer participants in soccer, basketball, volleyball and handball teams of lorestan province. The subjects were divided into 2 groups: Injured group (athletes with previous ankle sprains) and healthy group (athletes without previous ankle sprains). In this descriptive study we used Foot and ankle disability index sport and functional-performance tests ( figure of 8 hop test and side hop test)to determine ankle deficits and limitations .The Cronbachʹs alpha was used to determine the validity of FAD! sport (n ~ 0/793).The Subjects filled the FAD! sport out that included 8 questions via interviewing. In this index 100 points indicated no disability and lower than 100 indicated existence of deficits and limitations in athletes ankles. Then they participated in figure of 8 hop tesl included hopping in 8 shape course with the length of 5 meters and side hop test included 10 side hops repetitions in course with the length of 30 centimeters. times were recorded via stopwatch. After collect and assess of information distributions, we used pearson correlation coefficient for assessing of relationships and independent T test for differences between variables. Finally the results showed that: There was a significant relationship between previous ankle sprains and functionalperformance deficits in athletes. It means the athletes who had previous ankle sprains indicated functional-performance deficits more than healthy athletes in completion of mentioned functional-performance tests. The foot and ankle disability index sport is valid, sensitive and reliable for assessing and detecting of functional-performance deficits in athletes. Therefore we can use the FAD! sport for goals such as prevention, assessment and rehabilitation of ankle sprains easily.
