Postural control has classically been thought as achieved solely by mechanisms of feedback. However, since sensory feedback loops are slow and relatively noisy (Wolpert and Miall, 1996; Kawato et al., 1987), fast and coordinated body movements cannot be executed solely under feedback control. A modern view of motor control (called the internal model theory) proposes that the brain needs to acquirean inverse dynamics model of body movements to be controlled through motor learning, after which motor control can be executed in a pure feedforward (or predictive) manner (Kawato et al., 1987). This fundamental feature would allow modeling the capacity for plastic change and adaptation found in motor systems (Shadmehr and Krakauer, 2008), maintained throughout life by learning and learning-to-predictmechanisms.
