چکیده
The aim of this study was to investigate the feasibility of electrotactile feedback in closed loop training of force control during the routine grasping task. The feedback was provided using an array electrode and a simple six-level spatial coding, and the experiment was conducted in three amputee subjects. The psychometric tests confirmed that the subjects could perceive and interpret the electrotactile feedback with a high success rate. The subjects performed the routine grasping task comprising 4 blocks of 60 grasping trials. In each trial, the subjects employed feedforward control to close the hand and produce the desired grasping force (four levels). First (baseline) and the last (validation) session were performed in open loop, while the second and the third session (training) included electrotactile feedback. The obtained results confirmed that using the feedback improved the accuracy and precision of the force control. In addition, the subjects performed significantly better in the validation vs. baseline session, therefore suggesting that electrotactile feedback can be used for learning and training of myoelectric control.

A robust control strategy for closed-loop control of hindlimb movement induced by epidural electrical stimulation (EES) of the spinal cord is developed here. The method is based on adaptive fuzzy neuro-sliding mode control (AFNSMC). An AFNSMC is designed for multi-joint extension movement as well as flexion movement. The multi-joint flexion and extension movements are generated by stimulating t...
