Análise da velocidade e acurácia de movimentos em indivíduos após acidente vascular encefálico

Abstract

The Stroke might cause alterations in movement control due to the sequels of this process. Objective: Analyze the speed-accuracy trade-off of upper limb movement in individuals with sequels of Stroke through a computer software. Method: It is about a cross-sectional study, the sample was composed of 46 individuals divided into two groups: individuals post-stroke, between the ages of 35 and 83 years old, in which 10 were women and 14 were men; and 22 healthy controls aligned by age and sex, in which 8 were women and 14 were men, evaluated through the instruments: Mini mental state examination, Orpington prognostic scale, Fugl-Meyer Assessment Scale, dynamometer, box of blocks and throught the software “Fitts Reciprocal Aiming Task v.2.0. (Horizontal)”, that seeks to understand the motor control of the upper limb, verifying the speed and accuracy of movement through a computer task. Results: The individuals with sequels of Stroke showed a loss in the strength of the palmar grip and manual function. Besides, they showed a longer time in movement in all index of difficulty compared to Control group. However, they showed a similar behaviour to the healthy individuals throughout the execution of the index of difficulty. Conclusion: Thus, it can be concluded that the individuals with sequels of Stroke showed a deficit of the motor control of the upper limb, compared to the healthy individuals, however, these showed the same behavior, with a bigger deficit in the accuracy of movement.
