Intrinsic Risk Factors of Noncontact Ankle Sprains in Soccer
Background : Ankle sprain is an extremely common injury in soccer players . Despite extensive research , the intrinsic cause of this injury under noncontact conditions remains unclear . Purpose : To identify intrinsic risk factors for noncontact ankle sprains in professional soccer players . Study Design : Cohort study ; Level of evidence , 2 Methods : One hundred professional soccer players were assessed in the preseason for potential risk factors of noncontact ankle sprains . The assessment included ( A ) ankle joint asymmetries ( right-left ) in isokinetic muscle strength , flexibility , proprioception , and stability ; ( B ) somatometric asymmetries ; ( C ) previous injuries ; and ( D ) lateral dominance traits .  Noncontact ankle sprains were prospect ively recorded and diagnosed for a full competition period ( 10 months ) . Results : Seventeen of the players sustained at least 1 noncontact ankle sprain . Logistic regression revealed that players with ( A ) eccentric isokinetic ankle flexion strength asymmetries ( odds ratio [ OR ] = 8.88 ; 95 % confidence interval [ CI ] , 1.95 - 40.36 , P = .005 ) , ( B ) increased body mass index ( OR = 8.16 ; 95 % CI , 1.42 - 46.63 , P = .018 ) , and ( C ) increased body weight ( OR = 5.72 ; 95 % CI , 1.37 - 23.95 , P = .017 ) each had a significantly higher risk of a noncontact ankle sprain . A trend for younger players ( OR = 0.28 ; 95 % CI , 0.061 - 1.24 , P = .092 ) and for players with ankle laxity asymmetries ( OR = 3.38 ; 95 % CI , 0.82 - 14.00 , P = .093 ) to be at greater risk for ankle sprain was also apparent to the limit of statistical significance ( .05 < P < .10 ) . Conclusion : Functional strength asymmetries of the ankle flexors and increased body mass index and body weight raise the propensity for ankle sprains in professional soccer players . Age and asymmetries in ankle laxity are potential factors worth revisiting , as there was an indication for younger players and players with ankle instability to be at higher risk for ankle injury . Proper preseason evaluation may improve prevention strategies for this type of injury in soccer
