Stroke or cerebrovascular accident (CVA) is one of the main health problems worldwide, and in Brazil, it is accountable for 17% of cardiovascular disease cases. The Type A Botulinum Toxin (TAB), in addition to providing the relaxation of spastic muscles, promotes. The use of an isokinetic dynamometer is associated to such adjustment, which, after a few sessions, allows the decrease in hypertonia and the training of the antagonist musculature. Based on these assertions, the present study aims at analyzing the effectiveness of the isokinetic dynamometer training on the ankle extensor muscle performance in a spastic hemiparetic patient with stroke sequelae after TAB treatment. This is the case report of a male individual, with right hemiparesis, who underwent ten training sessions at the Cybex Humac Normr system, with a pre and post-training assessment and right after the first TBA treatment. The result of this study demonstrated improvement in muscle strength, total performance, torque and muscular power after eccentric training of the ankle extensor muscle and decrease in the muscular strength deficit in the lower limbs. We conclude that the TBA treatment, due to its relaxation effect on the spastic musculature, permitted a neuromuscular re-education and improvement of the selective motor control, allowing the ankle extensor muscle performance development through isokinetic dynamometry at low angular velocities, both in the eccentric and the concentric modes. Considering the lack of information in the literature, it becomes necessary to carry out a more comprehensive study, with a larger sample size and control group.
