1. A wearable device comprising:
a webbing extending between a first end and a second end, wherein the first end and the second end comprise respective fastening components that interact to enable connection between the first end and the second end to secure the webbing around a waist of a user such that the webbing defines (i) an interior surface to be placed against a body of the user and (ii) an opposite exterior surface when the first end is connected with the second end;
a controller secured to the webbing;
one or more sensors in electronic communication with the controller, wherein the one or more sensors are secured to the webbing and configured to generate center of gravity (COG) data indicative of a balance of the user;
a first plurality of electrodes secured on the interior surface of the webbing, wherein (a) the first plurality of electrodes are (i) in electronic communication with the controller, and (ii) configured to cause delivery of electrical pulses in accordance with a first electrical pulse stimulation protocol responsive to a first signal from the controller, (b) the first signal is provided from the controller responsive to a determination that a fall event for the user is likely, and (c) the electrical pulses are configured to stimulate a first target muscle group of the user; and
a second plurality of electrodes secured on the interior surface of the webbing, wherein (a) the second plurality of electrodes are (i) in electronic communication with the controller, and (ii) configured to cause delivery of electrical pulses in accordance with a second electrical pulse stimulation protocol responsive to a second signal from the controller, (b) the second signal is provided from the controller responsive to the determination that the fall event for the user is likely, and (c) the electrical pulses in accordance with the second electrical pulse stimulation protocol are configured to stimulate a second target muscle group of the user, wherein the controller is configured to modify the first electrical pulse stimulation protocol and the second electrical pulse stimulation protocol based at least in part on a muscle condition of the user.
