PURPOSE Ankle sprain is one of the most common injuries among athletes and instability and injury to this joint is responsible for long time loss of physical and recreational activity. Also, it can impose high costs to sport teams. Prevention of this injury is an important concern of practice and rehabilitation. One way of reducing the possibility of ankle joint injury is using an ankle orthosi...

OBJECTIVE: Deficits in static postural control related to chronic ankle instability (CAI) and fatigue have been investigated separately, but little evidence links these factors to performance of dynamic postural control. Our purpose was to investigate the effects of fatigue and CAI on performance measures of a dynamic postural-control task, the Star Excursion Balance Test. DESIGN AND SETTING: F...

CONTEXT Although lateral ankle sprains are common in athletes and can lead to chronic ankle instability (CAI), strength-training rehabilitation protocols may improve the deficits often associated with CAI. OBJECTIVE To determine whether strength-training protocols affect strength, dynamic balance, functional performance, and perceived instability in individuals with CAI. DESIGN Randomized c...
