A myocontrolled neuroprosthesis integrated with a passive exoskeleton to support upper limb activities

Abstract

This work aimed at designing a myocontrolled arm neuroprosthesis for both assistive and rehabilitative purposes.The performance of an adaptive linear prediction filter and a high-pass filter to estimate the volitional EMG was evaluated on healthy subjects (N=10) and neurological patients (N=8) during dynamic hybrid biceps contractions. A significant effect of filter (p=0.017 for healthy; p <4°).This study proposes a reliable and feasible solution to combine NMES with voluntary effort. © 2014 Elsevier Ltd.
