1. A ground reaction force plate apparatus comprising:
a plate for receiving a force to be measured as applied by a subject to the plate;
a base support on which a plurality of load cells are provided in an arrangement with only the load cells supporting the plate and with the plate spaced apart from the base support,
wherein each load cell is a sensor with a single sensing axis extending longitudinally along the sensor, wherein the sensor is configured to measure data relating to a force vector applied along the sensing axis when the subject applies the force to the plate;
wherein the single sensing axis of at least one of the sensors is oriented towards a centre of the plate; and
a data collection controller for logging time series measurements of the load cells over a time period in which the subject applies the force to the plate;
wherein the time series measurements of the load cells are processed to calculate three-dimensional components of the force applied by the subject to the plate over the time period.
