Was postural control adversely affected by chronic ankle instability? Effect sizes and 95% confidence intervals compare affected and unaffected limbs in those with unilateral chronic ankle instability. Whether postural control deficits exist in the affected limb versus the unaffected limb in those with unilateral CAI is unclear. Results of Tropp28 are not displayed due to wide confidence intervals around the effect size (COP area  =  .26, 95% confidence interval  =  −32.54, 33.06). EC indicates eyes closed; EO, eyes open; AP, anteroposterior; ML, mediolateral. Article reference numbers are superscripted.
