Efeito de uma sessão de facilitação neuromuscular proprioceptiva no tempo de reação e impulso agonista de indivíduos com doença de Parkinson

Abstract

Parkinson's disease (PD) is a degenerative and progressive disease in which there is a decrease in dopamine in the substantia nigra of the brain. This disorder causes motor problems such as resting tremor, muscular rigidity, bradykinesia and akinesia, as well as postural instability. Among the many treatment options, physiotherapy aims to minimize these problems, helping the individual to maintain their independence and improving their quality of life. To this end, methods such as NPF can be used, but, although it is well accepted in clinical practice, few studies relate the disease to PNF and variables related to the motor control of these subjects. With this in mind, this study sought to explore and understand the effects that the PNF method has on individuals with PD. To this end, three articles on the theme raised have been developed and will be presented in this dissertation. The first research involves a systematic review of the literature, whose purpose was to examine the existing content that correlates PNF with PD. The second and third studies analyzed the effects of a session based on the rhythmic initiation technique of the PNF method in individuals with PD, with respect to the variables of simple reaction time and agonist impulse. No significant differences were found for the variables proposed by the two studies, however, the results showed positive effects. In the second study, there was a decrease in the standard deviation of the final simple reaction time, which points to a lower variability and consequent uniformity of the evaluated aspect. In the third article, the mean area below the final agonist burst curve was greater than the mean initial area, which indicates that a rhythmic initiation session does not alter the pattern of muscle activation or variability in PD.
