Presented herein are systems, methods, and devices that provide for stimulation of nerves and/or targets such as mechanoreceptors, tissue regions, mechanoresponsive proteins, and vascular targets through generation and delivery of mechanical vibrational waves. In certain embodiments, the approaches described herein utilize a stimulation device (e.g., a wearable device) for generation and delivery of the mechanical vibrational waves. As described herein, the delivered vibrational waves can be tailored based on particular targets (e.g., nerves, mechanoreceptors, vascular targets, tissue regions) to stimulate and/or to elicited particular desired responses in a subject. As described herein, in certain embodiments, the delivery of mechanical stimulation to a subject provides for treatment of anxiety.
