Devices and methods for recovering from brain trauma using electrical stimulation

A system for providing rehabilitative neurostimulation therapy after neurological trauma, the system comprising:

• a wearable neurostimulation device configured to be donned on a head of a wearer, the wearable neurostimulation device comprising at least two electrodes;
• one or more sensors, each sensor of the one or more sensors i) integrated into the wearable neurostimulation device, and/or ii) in communication with a controller of the wearable neurostimulation device;
• and
• the controller, wherein the controller is configured to
• after a stroke or a traumatic brain injury (TBI) experienced by a wearer of the wearable neurostimulation device, deliver a first stimulation therapy to the wearer via the at least two electrodes of the wearable neurostimulation device, wherein
• the first stimulation therapy is delivered at least once within fourteen days of the stroke or TBI, and
• the first stimulation therapy is configured to curtail potential damage stemming from the stroke or TBI, and
• after the first stimulation therapy, deliver a second stimulation therapy coordinated with a training regimen for supporting the wearer in regaining abilities compromised by the stroke or TBI, wherein delivering the second stimulation therapy comprises
• collecting, from each respective sensor of the one or more sensors, a time sequence of sensor signals,
• analyzing the time sequence of sensor signals of each respective sensor of the one or more sensors to identify evidence of participation by the wearer in the training regimen, and
• responsive to identifying the evidence of participation, activating the second stimulation therapy via the at least two electrodes of the wearable neurostimulation device, wherein
• the second stimulation therapy comprises directing non-invasive stimulation pulses via the at least two electrodes to i) the auricular branch of the vagus nerve (ABVN) and/or ii) the auriculotemporal nerve (ATN) to induce neuronal plasticity, thereby promoting creation of new neural pathways corresponding to the training regimen.
