Summary:
The uncontrolled manifold analysis provides the synergy index, which quantifies how well a neuro-musculo-skeletal system of the animal body is coordinated to maintain a certain movement such as walking. The synergy index has experimentally been estimated from observed data. In this study, we propose a theory that gives the synergy index of a stable rhythmic movement from dynamical models by using the Floquet theory for limit cycles. The synergy index of an oscillatory motion in a simple model is calculated as an illustration of the theory.
