dc.description.abstract<b>Context:</b> Bilateral deficits of postural control during unipedal stance have been reported after an acute ankle sprain and CAI, but it is little evidence of postural control deficits on bipedal stance. <b>Objective:</b> To determine effects of acute lateral ankle sprain on postural control of the bipedal stance. <b>Design:</b> A case-control design. <b>Setting:</b> Laboratory. <b>Patients or Other Participants:</b> Ten patients with LAS (7 males and 3 females) and gender-matched 10 subjects without any history of ankle injuries participated in the study. <b>Intervention(s):</b> Postural control was assessed with Sensory Organization Test (SOT). Subjects were asked to perform 3trials on each of the 6 SOT condition and each trial was lasted for 20 s. <b>Main Outcome:</b> Equilibrium scores for each trial were calculated and utilized to quantify bipedal postural control with higher equilibrium score indicating better postural control. <b>Results:</b> The injured group had significant lower equilibrium scores when compared with the uninjured group on the stable surface with eyes open (U=78, p=.035; SOT Condition 1) and with eyes closed conditions (U=.81, p=.019; SOT Condition 2). No significant group differences were found in other 4 SOT conditions (p>.05). <b>Conclusions:</b> The findings indicate that an acute LAS may negatively affect the ability of postural control during quiet bipedal stance.
