INTRODUCTION: The return risk, after ankle sprain, can be associated with modifications of the postural stability and the muscular strength of the hip and the ankle. OBJECTIVES: The aim of this study was to evaluate the maximum gluteus activation during the walk on the treadmill, in women, comparing volunteers with second degree of ankle sprain history, with a group of volunteers with no sprain history. MATERIALS AND METHODS: Twenty-six young women were selected for the study, being 13 individuals with unilateral ankle sprain history and another 13 with no sprain history. The maximum gluteus activation was evaluated by the electromyography of surface (EMG), during the walk on the treadmill. RESULTS: On the group with sprain history there was not any significant difference on the measure of normal activation of the maximum gluteus during the walk, when compared unstable member and no unstable member (p > 0,57). However, on the group with no sprain history there was a significant difference between left and right members on the measure of normal activation of the maximum gluteus during the walk (p = 0,01). When comparing both groups, there was not any significant difference between unstable member and the others two members of the no sprain history group (p > 051). CONCLUSION: The results can be suggested that exist muscular, neuromuscular and sideways factors that can be determinate an adaptation after the ankle sprain, enabling a convenient walk activity.
