1. A method for measuring dynamic parameters of arterial wall motion, comprising:

  • presurizing a cuff that surrounds an artery;

    measuring the cuff pressure;

    determining from the cuff pressure a velocity and acceleration of the arterial wall;

    determining power of the arterial wall motion as the wall stretches and contracts in response to the cuff pressure, the power being defined as the product of the velocity of the arterial wall and the acceleration of the arterial wall; and

    from the power, determining changes in energy of the arterial wall, the energy being defined as the power measured over a predetermined time.
