A device that is a component of a balance/mobility management system equipped with built-in sensors, transducer and/or force plates that register movement of the patient when he/she adjusts his/her centre of gravity (COG) alignment according to the doctor's instructions, or, the platform provokes destabilizing perturbations and the output of these movements are measured and recorded to the system computer. It is used, e.g., for motor control test (MCT), posture studies, balance, mobility training, and/or sense of equilibrium studies. The patient will stand on this device.
