Trial-to-trial similarity and distinctness of muscle synergy activation coefficients increases during learning and with a higher level of movement proficiency
Muscle synergy analyses are used to increase our understanding of motor control. Spatially
fixed synergy vectors coordinate multiple co-active muscles through activation commands,
known as activation coefficients. To better understand motor learning, it is crucial to know
how synergy recruitment varies during a learning task and different levels of movement
proficiency. Within one session participants walked on a line, a beam, and learned to walk
on a tightrope–tasks that represent different levels of proficiency. Muscle synergies were …
