“Input-dependent” movement

Bodies that are moving for purpose – sport, life, work, play – should be developed, encouraged, and have the capacity to move without being entirely dependent on vision or thought/concentration. One purpose of rehabilitation would be to help patients and clients move with as little dependence on these inputs, as possible and can be expected in safe function. While it was once believed in an hierarchical model of motor control, that all movement was sensory-driven motor response, we know that this is no longer the case. We ADDITIONALLY now know that the brain does not perfectly store exacting motor patterns for thousands of different automatized movements. The brain and body interact to assess an environment, use known parameters about surfaces, weights, forces, friction, and chooses an appropriate pattern that links action to this perception.
