1. Apparatus to monitor the balance performance of a human user, which apparatus comprises:
- a pair of independent foot-plates upon which the user may stand with one foot on one foot-plate and the other foot on the other foot-plate, each foot-plate having an indication of the general position over which a user'"'"'s foot should be placed and having means to detect the load imparted to the foot-plate by the user, said load-detecting means associated with each foot-plate being arranged to detect the load imparted to the respective foot-plate about a first axis lying generally along the length of a user'"'"'s foot from toes to heel correctly placed with respect to the foot position indication and simultaneously to detect the load imparted to the foot-plate about a second axis generally at right angles to the first axis; and
display means to display the load imparted to each foot-plate, said display means includes a representation of the user'"'"'s feet and displays in a graphical manner, for each foot-plate separately but simultaneously, the position of the detected loads with respect to the representation of a user'"'"'s feet;
wherein the display means continuously and simultaneously displays both the position of the load between the user'"'"'s toes and heel for each foot and the side-to-side position of the load along the second axis for each foot to determine the balance performance for the human user.

Abstract
An apparatus and a method to monitor the balance performance of a user comprises two separate but similar foot-plates each slightly larger than the foot of a user. Each foot-plate includes detectors to detect the load imparted to the foot-plate by a user, about two axes generally at right angles with one axis lying more or less along the length of the user'"'"'s foot and the other axis transverse thereto. The outputs from the foot-plates are fed to a processing unit which drives a display device, graphically to show to the user on a real-time basis the detected loads and so to allow a user to modify his balance performance.

13. A method of providing a human user with a real-time indication of the user'"'"'s balance performance, comprising:
-
standing the user on a pair of independent foot-plates with one foot on one foot-plate and the other foot on the other foot-plate, each foot-plate having an indication of the general position over which a user'"'"'s foot should be placed and each being configured to detect the load imparted to the foot-plate by the user about a first and second axes substantially at right angles with the first axis lying generally along the length of a user'"'"'s foot from toes to heel correctly placed with respect to the foot position indication; separately detecting the load imparted to each foot-plate about said first axis thereof and simultaneously about said second axis generally at right angles to the first axis; and providing a graphical display device which includes a representation of the user'"'"'s feet and continuously displaying on said graphical display device, for each foot-plate separately but simultaneously, the load imparted on each foot-plate and the position of the detected loads along both the first axis and the second axis for each foot such that the position of the load between the user'"'"'s toes and heel for each foot and the side-to-side position of the load along the second axis for each foot are displayed to determine the balance performance of the human user.
