Inestabilidad crónica del tobillo y su influencia en el control postural en militares que pertenecen a la Brigada de Infantería Nro. 5to "GUAYAS".

Abstract

Chronic ankle instability is defined as a condition in which some patients suffer ankle sprains repetitvely, reporting a sensation of insecurity and pain on top of mechanical and functional instability. This kind of impairments are associated with a decrease of proprioception, generating a déficit in postural control. Objective: To stablish the relation between a chronic ankle instability and its influence on postural control in soldiers belonging to the fifth infantry brigade “GUAYAS”. Methodoloy: The approach is mixed with a correlational scope, cross section and with a non-experimental design. The sample was made of 80 active military between the ages of 24 to 54 which belong to the fifth infantry brigade “GUAYAS”. The instruments used for this study were medical records, Cumberland Ankle Instability Tool (CAIT), Weight Bearing Lunge Test (WBLT), Y-Balance test, Test Postural and Jack Test. Results: inside the total of 80 military, 56% showed chronic ankle instability. 44% didn’t show any kind of instability according to the CAIT test; 86% showed an active Jack test, and 14% was inactive. 89% showed limited dorsiflexión according to the weight bearing lunge test, however 11% didn’t show any Kind of limitation, Y balance test 89% have neuromotor deficits in dynamic balance, 11% do not have deficits in dynamic balance. Chi -squared statistical test established a relation between the variables CAIT, Jack test and weight bearing lunge with disturbances in the postural control, the most frequent alterations were hyperlordosis, divergent ankles, semiflexion of the knees, deformed fingers, and flat feet.
