Claim 1:
2. The apparatus in claim 1 wherein the 3-axis pivot is a gimble with a vertical yaw axis for rotation of a paddle when the user flexes and extends their wrist, a roll axis perpendicular to the yaw axis for rotation of a paddle when the user pronates and supinates their wrist, and a pitch axis perpendicular to the yaw axis and perpendicular to the roll axis for rotation of a paddle when the user adducts and abducts their wrist, and wherein the yaw axis is perpendicular to the tie bar and the roll axis is at an acute angle relative to the tie bar so the tie bar remains stationary so the rotation around any axis of a first paddle does not affect the rotation around any axis of a second paddle.
