Abstract
Various embodiments are described herein for a method and system for facilitating a gait of a user with a functional electrical stimulation (FES) orthotic system. In some described embodiments, the method includes receiving a foot orientation indicator for a foot of the user; receiving a body inclination indicator for the user; determining a motion state based on the foot orientation indicator and the body inclination indicator; and defining signal parameters for a stimulation signal based on at least the motion state. The motion state can indicate a movement status of the user and therefore, the stimulation signal can be applied to the user for facilitating the gait of the user.
Claims31
A method of facilitating a gait of a user with a functional electrical stimulation (FES) orthotic system, the method comprising:
- 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;
- 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;
- 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.
A functional electrical stimulation (FES) orthotic system for facilitating a gait of a user, the FES orthotic system comprising:
- a controller unit comprising a controller processor and at least one sensor, the controller processor configured to:
- receive 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;
- receive, from the at least one sensor, a body inclination indicator for the user, the body inclination indicator corresponding to a body position relative to the reference axis;
- determine a motion state based on the foot orientation indicator and the body inclination indicator, the motion state indicating a movement status of the user;
- and
- define signal parameters for a stimulation signal based on at least the motion state, the stimulation signal being applied to the user to facilitate the gait of the user.
