RESUMO
ObjectiveTo analyze the relationship of the static single-leg stance balance with ankle muscles strength and position sense in individuals with functional ankle instability (FAI). MethodsFrom March to May, 2023, 44 FAI individuals were recruited in Hebei Normal University, and the maximum isokinetic muscle strength (60°/s and 180°/s) and position sense as ankle flexion, extension, inversion and eversion were measured using isokinetic dynamometer; while the center of pressure (COP) sway distance and envelope area were measured as static single-leg stance with eyes open or closed using three-dimensional force plate. ResultsThe maximum isokinetic torque as ankle eversion at 180°/s correlated with the COP anterior-posterior sway distance with eyes closed (r = -0.378, P < 0.05). ConclusionExplosive ankle eversion strength is related with the balance in static single-leg stance, which may help to evaluate and intervent the ankle function of FAI individuals.
