Methods and related systems for modulating neural activity by cyclical blocking of conduction in peripheral neural structures with ultrasound are disclosed. In an aspect, neural activity is blocked cyclically with an ultrasonic blocking stimulus source positioned adjacent a skin surface in a vicinity of a nerve. In an aspect, a conduction block is produced in a sensory nerve. Neural modulation may be used, for example, to modulate an immune or inflammatory response or process.
