Such a postural instability have been demonstrated through increased Center of Pressure displacement or movement velocity when standing in single limb stance. It is unknown, however, the the anticipatory (APA) and compensatory (CPA) postural adjustments in these individuals during postural perturbations that are common during daily living, athletic and therapeutic activities. Therefore, the main objective of this study was to investigate the strategies of postural adjustment in individuals with FAI. The electromyographic (EMG) activity of postural muscles from a group of individuals with FAI and a matching control group were recorded and analyzed during the task of kicking a ball in single limb stance under different conditions of postural instability (even floor, foam and trampoline). The individuals with FAI showed a delay in the latency of the peroneus longus muscle (PL) when compared with the control group. The magnitude of APAs and CPAs were similar between groups, as well as within experimental conditions. However, the background muscle activity of the leg and thigh muscles was different between conditions, especially between even floor and trampoline conditions for both groups. These results suggest that therapeutic activities, functional exercises and balance training should aim in improving the reaction time of the PL muscle. / Indivíduos com instabilidade funcional de tornozelo (IFT) apresentam déficits de equilíbrio. Esses déficits são demonstrados, na maioria dos estudos, através do aumento do deslocamento ou velocidade de movimento do centro de pressão corporal durante apoio unipodal. Entretanto, pouco se conhece sobre os ajustes posturais antecipatórios (APA) e compensatórios (APC) desses indivíduos durante perturbações posturais, que são comuns durante atividades do cotidiano, esportivas ou terapêuticas. O principal objetivo deste estudo foi investigar as estratégias de ajuste postural de indivíduos com IFT. Para tanto, a atividade eletromiográfica (EMG) dos músculos posturais em indivíduos com e sem IFT foram registradas e analisadas durante a tarefa de chutar uma bola em apoio unipodal em diferentes condições de instabilidade postural (superfície plana, espuma e mini trampolim). Os indivíduos com IFT mostraram um atraso na latência do músculo fibular longo (FL) quando comparados ao grupo controle. As magnitudes dos APAs e APCs foram similares entre os grupos, bem como dentre as condições experimentais. No entanto, a atividade EMG basal para os músculos da perna e da coxa diferiram entre as condições, principalmente entre a superfície plana e o mini trampolim, para ambos os grupos. Sendo assim, atividades terapêuticas, exercícios ou treinamentos funcionais e de equilíbrio devem objetivar melhorar o tempo de reação do músculo FL.
