Passive gravity balancing orthosis apparatus for assisting and training patients suffering from muscle weakness by relieving the patients afflicted member of its weight using a plurality of articulated supporting members. Relief is obtained by identifying and fixing the center of mass of the combined articulated equipment members and supported weight of the patient's member in space using a defined parallelogram mechanism and once so identified making the total potential energy for any configuration of the articulated members of the system constant. At least one zero free length spring is used to connect the center of mass to a support outside the articulated members. Additional springs connect the center of mass to the articulated members.

An orthotic apparatus for assisting a person having an orthotic disability, such as foot drop, comprising an ankle belt component and a shoe/foot belt component connected by a pair of coil springs which are adjustably and releaseably attached between the belts. The foot at the beginning and end of the step will flex, due to the springs, and still return to lift the foot, which allows for normal walking and requires no special adaptation to the shoe.
