    ABSTRACT: Redundancy of the motor control system gives the central
    control structures options for solving everyday motor problems. The
    choice of particular control patterns is based on priorities
    (coordinative rules) that are presently unknown. Motor patterns
    observed in unimpaired young adults reflect these priorities. We
    hypothesize that in certain atypical conditions, which may include
    disorders in perception of the environment and decision-making,
    structural or biochemical changes within the central nervous
    system, and/or structural changes of the effectors, the central
    nervous system may reconsider its priorities. A new set of
    priorities will reflect the current state of the system and may
    lead to different patterns of voluntary movement. In such
    conditions, changed motor patterns should be considered not
    pathological but rather adaptive to a primary disorder and may even
    be viewed as optimal for a given state of the system of movement
    production. Therapeutic approaches should not be directed towards
    restoring the motor patterns to as close to "normal" as possible
    but rather towards resolving the original underlying problem. We
    illustrate this approach with movements in amputees and patients
    with Parkinson's disease, dystonia, and Down syndrome.

    KEYWORDS: Voluntary Movement, Motor Control, Movement Disorders,
    Coordination, Posture, Pre-programming, Parkinson's disease, Down
