Lateral ankle sprains are a common athletic injury accounting for 25-50% of injuries in sports that include running and jumping. Individuals who suffer from a lateral ankle sprain may develop residual symptoms of chronic ankle instability (CAI). CAI research has examined static and dynamic to static movements and unidirectional tasks; however, static to dynamic transitional movements remains largely unexplored in this population. Therefore, the purpose of this study was to evaluate dynamic postural stability during directional gait initiation in healthy young athletes (HYA) and athletes with CAI. There were no significant differences between the two groups for forward and directional gait initiation for center of pressure-center of mass separation at heel strike minus one, posterior and lateral displacement of the center of pressure during S1, step length, step velocity, and posterior and lateral velocity of the center of pressure during S1, We concluded that gait initiation at a 90? step angle may not be a challenging enough task to alter dynamic postural stability in those with CAI.
