Devices and methods for treating motion sickness using electrical stimulation

A system for inhibiting, reducing or eliminating motion sickness using neuromodulation, the system comprising:

• a neuromodulation device configured to be worn on a head of a subject, the neuromodulation device comprising
• a first conductive surface in electrical communication with at least one first electrode, wherein the first conductive surface is configured for positioning on or near an ear of the subject in a first tissue region, wherein the first tissue region is on, over, or adjacent to one or more first neural structures of a first set of neural structures, and
• a second conductive surface in electrical communication with at least one second electrode, wherein the second conductive surface is configured for positioning on or near the ear in a second tissue region on, over or adjacent to one or more second neural structures of a second set of neural structures;
• and
• a controller comprising processing circuitry configured to deliver therapeutic stimulation pulses for providing motion sickness therapy to the subject, wherein delivering the therapeutic stimulation pulses comprises
• delivering a first series of stimulation pulses to the at least one first electrode, wherein the first series of stimulation pulses is configured to modulate peripheral activity via modulating central neural autonomic structures, and
• delivering a second series of stimulation pulses to the at least one second electrode, wherein the second series of stimulation pulses is configured to modulate one or more areas in a brain stem of the subject.
