Perturbation time for the flat foot was significantly longer (P &lt; 0.05) for the sprained group (2.2 \u00b1 0.4 seconds) than for controls (1.8 \u00b1 0.5 seconds). However, failure rate was higher (P &lt; 0.05) among the sprained group than controls for perturbation with the foot flat and baseline oscillation on demi-pointe.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Findings demonstrated altered sensorimotor control in chronically unstable ankles.
