Systems and methods are provided for combined ultrasound and electrical stimulation for treating inflammation, autoimmune disorders, rheumatoid arthritis, and the like. Noninvasive ultrasound stimulation may be applied to the spleen, joints, limbs, or a region experiencing pain that has local swelling, and electrical stimulation may be applied to the face, neck, or other body region to access a peripheral nerve, vagus nerve, trigeminal nerve, or other nerves in appropriately-timed patterns to drive therapeutic effects. Stimulation timings or delay timings may be optimized based upon a desired clinical effect or treatment. Multiple targets may be stimulated in a coordinated fashion to better mimic natural physiology. A wearable ultrasound phased array device may be used to beam form energy to target the spleen while also having imaging capabilities to track the motion of the spleen to maintain localized stimulation of target regions.
