Effects of two recovery methods on the leg muscle fatigue of oceanauts in a manned submersible
Medycyna Pracy, 2022 Background The cabin of the manned submersible is a narrow and sealed space. The long-time work of oceanauts is easy to cause muscle fatigue and stiffness, which reduces efficiency.

Changes in EMG–EMG Coherence During Hand Grasp Movements [PDF]
International Journal of Humanoid Robotics, 2014 It is challenging to recognize human hand grasp movements through electromyogram (EMG) signals. In this paper, EMG–EMG coherence measure is used to describe correlations of EMG recordings during different hand grasp movements. Meanwhile, linear discriminant analysis (LDA) is utilized to evaluate the performance of the EMG–EMG coherence measure for ...
