ABSTRACT:
An apparatus is disclosed for monitoring the movement and force production of the lumbar spine during flexion and extension in each of several sagittal-frontal planes of the body, as well as during movement into he transverse (twisting) plane. The apparatus includes a rotatable platform upon which the patient is adapted to stand, and the platform is pivotable about a vertical axis, so that the platform may be pivoted to a selected angle and locked in position. A pelvic stabilization belt is mounted to the platform, and an overhead frame member is provided for rotation about a horizontal axis which is adapted to pass through the lumbro-sacral junction of the patient. An upper body yoke is mounted to the overhead frame member for rotation about a generally vertical axis which is perpendicular to the horizontal axis. An upper body engaging member is mounted to the yoke, and a control system is provided whereby the apparatus may be operated in a flexion/extension mode, or in a twisting mode, and with the foot platform in a selected angular position.
