Control of a robotic knee exoskeleton for assistance and rehabilitation based o...
Villa-Parra,Ana Cecilia; Delisle-Rodriguez,Denis; Botelho,Thomaz; Mayor,John Jairo Villarejo; Delis,Alberto López; Carelli,Ricardo; Frizera Neto,AnselmoIntroduction: This work presents the development of a novel robotic knee exoskeleton controlled by motion intention based on sEMG, which uses admittance control to assist people with reduced mobility and improve their locomotion. Clinical research remark that these devices working in constant interaction with the neuromuscular and skeletal human system improves functional compensation and rehabilitation. Hence,...
Dexterous hand gestures recognition based on low-density sEMG signals for upper...
Mayor,John Jairo Villarejo; Costa,Regina Mamede; Frizera Neto,Anselmo; Bastos,Teodiano FreireAbstract Introduction Intuitive prosthesis control is one of the most important challenges in order to reduce the user effort in learning how to use an artificial hand. This work presents the development of a novel method for pattern recognition of sEMG signals able to discriminate, in a very accurate way, dexterous hand and fingers movements using a reduced number of electrodes, which implies more confidence a...
Adaptation of a smart walker for stroke individuals: a study on sEMG and accele...
Loterio,Flávia Aparecida; Valadão,Carlos Torturella; Cardoso,Vivianne Flávia; Pomer-Escher,Alexandre; Bastos,Teodiano Freire; Frizera-Neto,AnselmoAbstract Introduction: Stroke is a leading cause of neuromuscular system damages, and researchers have been studying and developing robotic devices to assist affected people. Depending on the damage extension, the gait of these people can be impaired, making devices, such as smart walkers, useful for rehabilitation. The goal of this work is to analyze changes in muscle patterns on the paretic limb during free a...
Comparison of the influence of stimuli color on Steady-State Visual Evoked Pote...
Tello,Richard Junior Manuel Godinez; Müller,Sandra Mara Torres; Ferreira,André; Bastos,Teodiano FreireIntroductionThe main idea of a traditional Steady State Visually Evoked Potentials (SSVEP)-BCI is the activation of commands through gaze control. For this purpose, the retina of the eye is excited by a stimulus at a certain frequency. Several studies have shown effects related to different kind of stimuli, frequencies, window lengths, techniques of feature extraction and even classification. So far, none of th...
