In our daily activities, even the simplest movement requires the activation of many muscles simultaneously. Muscles synergies represent a fundamental organizing principle of the neuromuscular system, acted in the central nervous system that recruits muscles and groupings them together within units to efficiently execute motor tasks in a coordinate manner. Understanding the concept of muscle synergies and their role in motor control is crucial in various fields. Research has shown that voluntary muscle synergies are highly adaptable and can be modified based on task requirements, training, and rehabilitation. The present thesis focuses on a novel approach, which has been introduced recently that complements conventional voluntary muscle synergies (task-muscle synergies): muscle synergies obtained from transcranial magnetic stimulation using motor evoked potentials (evoked-muscle synergies).
