1. A wearable device configured to:
store a baseline center of gravity (COG) profile for a user, wherein (a) the baseline COG profile defines a plurality of COG offset criteria indicative of potential fall events, (b) each of the plurality of COG offset criteria corresponds to at least one of a body position or a body movement, and (c) the wearable device is configured to be worn by the user;
generate COG data in real-time via one or more sensors of the wearable device;
determine whether the COG data generated in real-time satisfies at least a first COG offset criterion of the plurality of COG offset criteria indicative of a potential fall event;
upon to determining that the COG data satisfies at least the first COG offset criterion, identify a first pulse stimulation protocol for a first plurality of electrodes of the wearable device and a second pulse stimulation protocol for a second plurality of electrodes of the wearable device, wherein (a) the first pulse stimulation protocol is defined based at least in part on the baseline COG profile and is configured to stimulate a first set of target muscles of the user's to at least partially counteract the potential fall event in real- time while the COG data satisfies at least the first COG offset criterion, and (b) the second pulse stimulation protocol is defined based at least in part on the baseline COG profile and is configured to stimulate a second set of target muscles of the user's to at least partially counteract the potential fall event in real-time while the COG data satisfies at least the first COG offset criterion;
upon identifying the first pulse stimulation protocol and the second pulse stimulation protocol, determine a user muscle condition, wherein the user muscle condition is relevant for the user while the COG data satisfies the first COG offset criterion;
modify the first pulse stimulation protocol and the second pulse stimulation protocol to counteract the potential fall event based at least in part on the user muscle condition; and
cause (a) the first plurality of electrodes to provide one or more first electrical pulses corresponding to the modified first pulse stimulation protocol to stimulate the first set of target muscles of the user to at least partially counteract the potential fall event based at least in part on the user muscle condition, and (b) the second plurality of electrodes to provide one or more second electrical pulses corresponding to the modified second pulse stimulation protocol to stimulate the second set of target muscles of the user to at least partially counteract the potential fall event based at least in part on the user muscle condition.
