Systems, devices, components and methods for triggering or inducing resonance or high amplitude oscillations in a cardiovascular system of a patient
Various embodiments of systems, devices, components, and methods for providing external therapeutic vibration stimulation to a patient are disclosed and described. Therapeutic vibration stimulation is provided to at least one location on or adjacent to a patient's skin (such as through clothing or a layer disposed next to the patient's skin), and is configured to trigger or induce resonance or high amplitude oscillations in a cardiovascular system of the patient. Inducing such resonance can aid in training autonomic reflexes and improve their functioning.
