Claim Text:
1. A method of facilitating a gait of a user with a functional electrical stimulation (FES) orthotic system, wherein at a controller unit, the method comprises: receiving a foot orientation indicator for a foot of the user, the foot orientation indicator corresponding to an angular position of the foot relative to a reference axis, the reference axis being a longitudinal axis of the user in an initial state; receiving a body inclination indicator for the user, the body inclination indicator corresponding to a body position relative to the reference axis; receiving an acceleration indicator for the user; determining a motion state based on the foot orientation indicator and the body inclination indicator, the motion state indicating a movement status of the user; identifying the motion state is a fallen state when the acceleration indicator exceeds a drop acceleration threshold and the body inclination indicator exceeds a drop inclination threshold; identifying the motion state is an active state when the acceleration indicator indicates that the user is not stationary and is less than the drop acceleration threshold; and defining signal parameters for a stimulation signal based on at least the motion state, the stimulation signal being applied to the user for facilitating the gait of the user.
