Efeitos agudos da etcc associada ao treino motor em pacientes com sequelas de avc: relato de casos.

Abstract

Neurological deficits due to stroke depend on the extent, location and collateral circulation of the affected area, being one of the main causes of incapacity and displacement of the work. Hemiparesis is one of the most characteristic sequels. Objectives: To evaluate the accute effects of tDCS and motor training in manual dexterity in hemiparetic patients after stroke. Methods: This is a descriptive double-blind, controlled series of cases. To carry out the study, each volunteer had two intervention moments with the researcher existing between these an interval of one week. In each intervention, patients passed by one of the two stimulation conditions (real or simulated), whitch was designated as a lottery form. However, neither the patients nor the researchers should know what was the stimulation condition in interventions. To evaluate, were used as scales: Boxa nd Blocks Test (BBT) used to evaluate gross manual dexterity; Nine Hole and Peg Test (9HPT) used to evaluate the fine manual dexterity; and hand grip dynamometry, used to estimate strength and neuromuscular response. The evaluation was divided into 3 distinct times: baseline (T0), after the tDCS (T1), and after the functional training (T2). Results: In the condition of real stimulation in the BBT aspect, 9BP and dynamometry, it was possible to observe the improvement in both patients in the general context. The simulated stimulation condition presented a general performance decrease, except in the 9BP test, where a patient had an improvement before the worsening of performance. In gross motor and force tests, after tDCS and motor training, all patients had final results better than inicial ones. Conclusion: It was possible to verify performance improvement of fine and gross manual dexterity, as well as in the grip strength of the affected hand. We suggest further research on this important therapeutic tool and its associations.
