Avaliação quantitativa da adaptação sensório-motora a uma tarefa funcional

Abstract

Movement is an essential aspect of life and allows the human being to interact with the environment, but the mechanism by which the neuromusculoskeletal system uses to promote improvement in the performance of motor tasks has not yet been well delineated. Objective: Quantitatively characterize the evolution pattern of the biomechanical strategies adopted in the process of sensorimotor adaptation in healthy individuals, exposed to a functional motor task demand. Methodology: This is a cross-sectional, observational study, including 30 healthy subjects exposed to a motor task, consisting of a video game that uses the Nintendo Wii® platform to identify the improvement of motor performance combined with the use of a software of kinematic analysis of the movement, the CvMob, to characterize the evolution of motor strategies throughout the practice of the game. Results: 29 subjects, 1 exclusion, mean age of 26 years ± 3.05, of which 17 (58.63%) were female and 12 (41.37%) were male. The number of hits, which shows improvement in performance, presented an initial mean of 17.9 ± 6.05 and a final mean of 28.90 ± 1.87. The variability was measured by the percentage of the standard deviation in relation to the mean in the first evaluation, which was 33.38% for the score in the game and 28.90% for the Elements of Motion (EOM) and in the seventh the percentage of the standard deviation in the score game score was 6.49% and in EOM, 24.40%. It was possible to identify a trend to the inverse correlation between the score and the amount of EOM with p = 0.00013 and r = - 0.977. Conclusion: During the process of sensory-motor adaptation there is a modification in the strategies used in the task, characterized by the reduction in the number of EOM, suggesting the development of a more efficient final motor strategy.
