Motor synergies is a concept within motor control research positing that the central nervous system simplifies the control of the body's numerous degrees of freedom by coordinating multiple muscles, joints, or other elements to function as coherent units. This research area investigates the structure, emergence (including during learning), and functional role of these coordinated patterns, exploring how they reduce motor complexity, contribute to efficient and stable movement execution, and offer a theoretical framework to address the degrees of freedom problem in motor control.
