Forest plot of static balance with eyes open (a) and eyes closed (b) comparing CAI with control. Hertel and Olmest-Kramer, 2007a (velocity of centre pressure in mediolateral direction) and b (velocity of centre pressure in anteroposterior direction) [30]; Mitchell et al., 2008a (velocity of centre pressure in mediolateral direction) and b (velocity of centre pressure in anteroposterior direction) [33]. CAI chronic ankle instability, CI confidence interval, CON control, SMD standardized mean difference. Positive SMD indicates balance deficits in CAI
