Method for moving a portion of a paralyzed limb

Abstract

A method of moving a portion of a limb which has been partially paralyzed, comprises implanting a biasing device in the body of a person having a limb which is at least partially paralyzed, and attaching one end of the biasing device to a first portion of the limb to be moved. Another end of the biasing device is anchored to a second portion of the limb. The biasing device is operable for biasing the first portion of the limb in a first direction to hold the first portion in a first position, and the biasing device is further operable for allowing the first portion to move in a second direction when a force from a non-paralyzed muscle group acts on the first portion of the limb. The biasing device continues to bias the first portion in the first direction so that the limb returns to the first position when the force from the muscle group is removed.
