Claim Text:
1. A rehabilitation system including a compliant bimanual rehabilitation device, comprising: a base that defines a left side, a right side, a front side, a rear side, an x-axis, a y-axis, and a z-axis of said device, wherein said base has a top side and a bottom side; a carrier assembly slidably coupled to said base, said carrier assembly being slidable along the y-axis of said device; an upper assembly rotationally coupled to said carrier assembly, said upper assembly being rotational about the z-axis of said device, said upper assembly having a left end corresponding to said left side of said device and a right end corresponding to said right side of said device; a left handle slide slidably coupled to said left end of said upper assembly, said left handle slide being slidable along the x-axis of said device; a right handle slide slidably coupled to said right end of said upper assembly, said right handle slide being slidable along the x-axis of said device; a left compliant handle assembly coupled to said left handle slide and extending from said left handle slide; a right compliant handle assembly coupled to said right handle slide and extending from said right handle slide; a left handle fixedly coupled to said left compliant handle assembly; a right handle fixedly coupled to said right compliant handle assembly, wherein one of said left handle and said right handle is a guiding handle and the other of said left handle and said right handle is a following handle, wherein said left handle and said right handle are indirectly linked to each other at an adjustable, predetermined coupling stiffness, such that when said device is in use, a paretic arm of a user or operator of said device is linked to a sound arm of said user of said device, such that a movement of said guiding handle dictates a corresponding movement of said following handle according to a predetermined symmetry mode; said left handle and said right handle indirectly linked to each other via said left handle slide and said right handle slide, said left handle slide and said right handle slide being coupled to each other, thus also coupling said left compliant handle assembly and said right compliant handle assembly to each other; said left handle slide and said right handle slide being coupled to each other via a cable and pulley assembly including at least one cable and at least two pulleys; wherein when said at least one cable is looped around said at least two pulleys an even number of times, said left handle and said right handle move in a same absolute direction, and when said at least one cable is looped around said at least two pulleys an odd number of times, said left handle and said right handle mirror each other.
