Estimation of Joint Kinematics and Fingertip Forces using Motoneuron Firing Activities: A Preliminary Report

2021 10TH INTERNATIONAL IEEE/EMBS CONFERENCE ON NEURAL ENGINEERING (NER), pp. 1035–1038.

By: F. Xu*, Y. Zheng* & X. Hu*

topics (OpenAlex): Muscle activation and electromyography studies; EEG and Brain-Computer Interfaces; Neuroscience and Neural Engineering
TL;DR: A novel decoding method that used finger-specific motoneuron firing frequency to estimate joint kinematics and fingertip forces and showed that the MU firing based approach led to smaller prediction errors for both joint angles and forces compared with the conventional EMG amplitude based method.
