Abstract
The present invention is a method and device for reducing trembling of a limb of a human subject. The method comprises suspending a mass from the limb via a suspension configuration. The suspension configuration having an effective spring constant and/or a non-zero coefficient of damping in at least one direction such that the mass is driven to oscillate in the at least one direction out of phase relative to the trembling motion. A further embodiment includes a motion sensor to sense the motion of the limb, an actuator to generate the damping force, and a control unit that is responsive to the motion sensor and actuator to generate a damping force that alleviates trembling.
