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