Abstract: This invention discloses, a therapeutic exerciser system, suspended from a horizontal trapezoid frame, with a movable balance point, connected by a cleated fiddle block pulley assembly, to an eye bolt installed in an overhead beam, or to the rolling traveler on an overhead track, and providing specially developed support sections. The disclosed therapeutic exerciser system, has a common upper body support section combined with, any one of three, inter-changeable, different types, of lower body supports; a bucket seat, a crotch piece, or a pelvic support. The range of motion available to the user is determined by their own ability and by the type of support that the bucket seat, crotch piece or pelvic support provides. This invention can also be used, by a treatment provider, to facilitate vestibular stimulation and sensory integration techniques and other treatment modalities, for users who may be unable to move themselves.
