  • Walking and balance exercise device
    Patent number: 7803125
    Abstract: A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s).
    Type: Grant
    Filed: June 9, 2009
    Date of Patent: September 28, 2010
    Assignee: Rehabilitation Institute of Chicago Enterprises
    Inventors: Julio Santos-Munne, Alex Makhlin, Ela Lewis, Michael Peshkin, David A. Brown, J. Edward Colgate, James L. Patton, Benjamin L. Rush, Doug Schwandt

A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s). Wheel modules are independently powered to both rotate and steer, and, responsive to the control unit, are capable of rolling the exercise device in a direction of travel intended by the patient.
