Thirty-one
young adults with self-reported CAI were randomly assigned to an intervention group (six males and 10 females) or a control group
(six males and nine females). The intervention consisted of a 4-wk supervised balance training program that emphasized dynamic
stabilization in single-limb stance. Main outcome measures included the following: self-reported disability on the Foot and Ankle
Disability Index (FADI) and the FADI Sport scales; summary center of pressure (COP) excursion measures including area of a 95%
confidence ellipse, velocity, range, and SD; time-to-boundary (TTB) measures of postural control in single-limb stance including the
absolute minimum TTB, mean of TTB minima, and SD of TTB minima in the anteroposterior and mediolateral directions with eyes
open and closed; and reach distance in the anterior, posteromedial, and posterolateral directions of the Star Excursion Balance Test
(SEBT)
