Abstract
An orthesis has a lever system having fulcrum simulating the patient'"'"'s shoulder joint. The system includes a series of levers facing the patient'"'"'s trunk to which is applied a force corresponding to that which is represented by the weight of the arm. The force is applied on the lever system at a point which is variable in response to the movement of the arm so that it approximately lies on the line between the center of gravity of the arm and the fulcrum joint.
