Bayesian Filtering of Surface EMG for Accurate Simultaneous and Proportional Prosthetic Control

Hofmann, David; Jiang, Ning; Vujaklija, Ivan; Farina, Dario (Institute of Electrical and Electronics Engineers, 2016-12-01)

The amplitude of the surface EMG (sEMG) is commonly estimated by rectification or other nonlinear transformations, followed by smoothing (low-pass linear filtering). Although computationally efficient, this approach leads ...
Motor Unit Characteristics after Targeted Muscle Reinnervation

Kapelner, Tamas; Jiang, Ning; Holobar, Ales; Vujaklija, Ivan; Roche, Aidan; Farina, Dario; Aszmann, Oskar C. (Public Library of Science, 2016-02-22)

Targeted muscle reinnervation (TMR) is a surgical procedure used to redirect nerves originally controlling muscles of the amputated limb into remaining muscles above the amputation, to treat phantom limb pain and facilitate ...
Online mapping of EMG signals into kinematics by autoencoding

Vujaklija, Ivan; Shalchyan, Vahid; Kamavuako, Ernest Nlandu; Jiang, Ning; Marateb, Hamid R.; Farina, Dario (Biomed Central, 2018-03-13)

Background: In this paper, we propose a nonlinear minimally supervised method based on autoencoding (AEN) of EMG for myocontrol. The proposed method was tested against the state-of-the-art (SOA) control scheme using a ...
