(WO9808572-A1)      The omnidirectional treadmill (1) comprises a frame and a track assembly mounted on the frame. The track assembly has a user active surface (2) for supporting the user (3). It has two supports with each moveable in a different direction. They are driven by an X-axis control motor (7) and a Y-axis control motor (8). Each support has several support members rotatable about axes parallel to the support direction. The combined movements of the user support members result in omnidirectional user movement.    A balance cuff (10) attaches near the user's centre of balance and a hinge (11) at the small of the user's back connects the cuff to a support strut (12). This links the user with the X-Y tracking mechanism (13) of the support frame (14). The controller (4) responds to the directional orientation of the user to selectively control the operation of the first and second drivers. This allows the directional user movement to conform with the orientation of the user on the active surface.    USE/ADVANTAGE -   E.g. rehabilitation, training, exercise or virtual reality equipment. Allows user to walk or run in any direction. Enables user to assume any posture e.g. kneeling, crawling, sitting and lying. Positions user at centre of surface.
