NOVELTY - The apparatus (100) has an user positioning unit (120) connected with a frame for positioning a user with respect to an exercise device (124) and the frame to perform a predetermined exercise. A device adjustment unit positions the exercise device with respect to the frame and a properly positioned user to accommodate user size and shape diversity. The adjustment unit aligns the exercise device with a predetermined body part of the user. A feedback unit provides feedback to the user to indicate whether the predetermined exercise is performed correctly.    USE - Exercise and rehabilitation apparatus for use by user. Uses include but are not limited to rehabilitation patient, healthy exerciser, and caregiver e.g. medical doctor, nurse, and physical therapist.    ADVANTAGE - The exercise device allows rehabilitation patients and the general public to execute important coordination, strength, and stability exercises easily with minimal or without guidance from a physical therapist and health or fitness professional. The apparatus has a slight difference in directional resistance providing new coordination challenges, to increase rehabilitation and overall medical improvement with minimum length of time. The apparatus provides new ways to stimulate important muscular activation, and coordination patterns of a patient by the physical therapist while ensuring that the patient is able to execute the movements singly, without supervision. The apparatus reduces imbalances in muscular coordination around a joint of the user during injury, thus controlling or minimizing susceptibility by developing increased and improved joint stability.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for employing an exercise and rehabilitation apparatus.
