Abstract: A method for determining postural stability of a person can include acquiring a plurality of pressure data points over a period of time from at least one pressure sensor. The method can also include the step of identifying a postural state for each pressure data point to generate a plurality of postural states. The method can include the step of determining a postural state of the person at a point in time based on at least the plurality of postural states.

Abstract: Systems and methods for monitoring equilibrium of a user are presented. A stability monitoring device in a shoe insole area utilizes pressure sensors to measure pressure information in real-time. The pressure information is transmitted over an RF network to a device for analyzing the pressure information and calculating postural state information including the current postural state, next postural state, and/or a range of postural stability. The person or a third party may be notified if the postural state information indicates an unstable state. Additionally, the postural state information may be analyzed to determine activity level of the user, diagnostic information, or performance information. Metrics may be displayed by the system for assisting physical therapy or training regimens.
