Lateral ankle sprains are one of the most common injuries suffered by athletes in sports. It is estimated that an upwards of 70% of athletes will develop chronic ankle instability following an initial sprain. Despite the high prevalence of CAI, knowledge of the mechanism or prevention of repeated ankle sprains is limited . Since most sprains occur in the latter halves of matches, the purpose of this study was to determine the effects of fatigue on lower limb movement variability in individuals with and without CAI during running gait using 3D inertial sensors
