Before revision: Objective: Higher-order tensor decompositions have hardly been used in muscle activity analysis despite the fact that multichannel electromyography (EMG) datasets used in muscle synergy studies naturally present multi-way structure .
After revision:  Higher-order tensor decompositions have hardly been used in muscle activity analysis despite the fact that multichannel electromyography (EMG) datasets used in muscle synergy studies naturally present multi-way structure .
