The association Between Muscle and Kinematic Synergies When Walking at Different Speeds

Abstract

Many studies have shown that complex tasks such as walking are controlled by groups of coactive muscles or joints, or synergies. In the analysis of muscle synergies, it is important to reveal their biomechanical functions for specific tasks. However, how the function of muscle synergies is altered by walking speed has not been studied in detail. In this study, we analyzed the relationship between muscle synergies and kinematic synergies when walking at different speeds. In addition, we extracted the kinematic synergies from the angular velocity data in order to make it easier to correlate the muscle synergies and the kinematic synergies.
