Entropy Analysis of Kinematics and Electromyography Signals during Upper Limb Tracking Tasks

Abstract

Four kinds of upper limb tracking tasks with increasing complexity were performed to study the changes of kinematics and electromyography (EMG) signals towards different task demands. Results showed the entropy of elbow angle increased when tracking became more difficult while it was the opposite for biceps EMG signals. Entropy analysis might reveal the mechanisms of human motor control in neuromuscular system.
