Parâmetros de estimulação funcional através da Fes-cycling em indivíduos com lesão de neurônio motor superior pós-AVC

Abstract

Introduction: Functional electrical stimulation cycling (FES-Cycling) is a type of aerobic exercise used with individuals after a stroke. The parameters of electrostimulation (ES) in FESCycling, in order to maintain a constant rhythm in the cycling movement, are not clear in the literature. Thus, it is necessary to test the ES parameters and the anticipatory muscle activation strategy in FES-Cycling. Objective: to investigate the stimulation parameters in FES-Cycling, in post-stroke individuals who presented spasticity or paresis of the lower limb and how to anticipate muscle activation during FES-Cycling. Method: Study of cases in which the electrostimulation parameters and the initial ES angulation in FES-Cycling were investigated in two individuals after chronic stroke. Results: the participants had different characteristics between them. The values found in our data of the electrostimulation parameters are similar to those found in other studies. However, there were variations in relation to the initial ES angulation. Final Considerations: The electrostimulation parameters used were satisfactory for use in FES-Cycling in post-stroke individuals with sequelae of spasticity in the plantar flexors and important weakness in the lower limbs. However, the parameters must be adjusted individually to generate visible muscle contraction and assist in cyclic movement during exercise.
