Abstract
Introduction

The cerebral vascular accident (CVA) is one of the pathologies that cause larger attack in the neuromuscular function. Patients with CVA sequel, demonstrate difficulties in voluntary motor control, the spasticity is the main interference cause. Several therapeutic resources can be instituted to rehabilitate those patients. The Electric Functional Stimulation constitutes an electrotherapist resource that promotes muscular contraction with functional objectives. Since then the objective of this study was to analyze the gait biomechanics difference on 6 hemiparetic patients divided in two random groups, and the functional electric stimulation was used in the first group in the triceps sural muscle. The second group in the previous tibiae muscle. This study was accomplished 4 times a week, during 30 minutes in the period of 4 weeks. The patients were a pre and post test appraised, being the Cerny protocol used to evaluate the gait, modified Ashworth scale to evaluate the muscular tonus, the manual force test and goniometer to analysis of the ankle movement amplitudes. The obtained balances were submitted to the statistical analysis using t-test student pared. Was verified that the first group presented a better result in relation to second group. In agreement with the study, the functional electric stimulation resulted in improvement in the spasticity reduction, movement amplitude increase and gait enhancement.
