Abstract
This is an ankle and/or wrist exercising device capable of simultaneous rotational movement about any single axis and/or any combination of two or three axes with the resistance to movement provided by the opposite limb, ergometer or a second person and with the motion being synchronized for each foot or hand relative to the opposite foot or hand. The device is comprised of two U-shaped yokes rotatably mounted upon a base, adapted to rotate about a Y axis and rotatably coupled to one another. There are two U-shaped brackets rotatably coupled to each of said U-shaped yokes, adapted to rotate about a Z axis perpendicular to said Y axis and rotatably coupled to one another. Two U-shaped gimbals are integrally coupled to each of said U-shaped yokes. Two stirrups are rotatably mounted upon each of said U-shaped gimbals and adapted to rotate about an X axis. The X axis is perpendicular to the Y axis and the Z axis. Each of said stirrups is coupled to the other by a beam adapted to transmit X axis motion.
