title: Correlation of ankle eversion to inversion strength ratio and static balance in dominant and non-dominant limbs of basketball players.
abstract: BACKGROUND
  To compare ankle eversion to inversion strength ratio (E/I R) and static balance control between the dominant and non-dominant limbs of basketball players and to correlate ankle E/I R and static balance control in the dominant and non-dominant limbs of basketball players.
  
  
  METHODS
  Twenty-one healthy basketball players in the age-group of 18-25 years participated in this study. Isokinetic ankle eversion and inversion muscle strength was assessed at 30°/s and 120°/s in both dominant and non-dominant limbs using the Biodex isokinetic dynamometer. Similarly balance was assessed on a force platform with eyes open and eyes closed in both dominant and non-dominant limbs.
  
  
  RESULTS
  Repeated measure ANOVA for strength measurement, found that there was significant main effect of speed, P=0.001 (P<0.05). However, there was no significant main effect in the sides P=0.099 (P<0.05).There was significant main effect of sides with respect to balance. Balance was affected more in non-dominant limb P=0.000 as compared to dominant limb. However, there was not much of a significant difference with eyes open and eyes closed position.
  
  
  CONCLUSIONS
  The E/I ratio was >1.0 at the angular velocity of 120°/s increasing the chances of ankle injuries in basketball players. There was no correlation between ankle strength and balance in both dominant and non-dominant limbs.
