Fatigue’s Effect on Eversion Force Sense in Individuals with and without Functional Ankle Instability
Context: Force sense (FS), the proprioceptive ability to detect muscle-force generation, has been shown to be impaired in individuals with functional ankle instability (FAI). Fatigue can also impair FS in healthy individuals, but it is unknown how fatigue affects FS in individuals with FAI. Objective: To assess the effect of fatigue on ankle-eversion force-sense error in individuals with and without FAI. Conclusions: Greater AE indicates that FAI individuals are less accurate in their force production. Fatigue impaired force sense in all subjects equally. These deficits provide evidence of impaired proprioception with fatigue and in individuals with FAI.
