A method of treatment by vibration stimulation is provided. The method includes providing an expandable stimulation member adapted to impart vibrations to body tissue of a human subject introducing the stimulation member into a body cavity of the human subject expanding the stimulation member to a volume such that the stimulation member abuts against body tissue within the body cavity bringing the stimulation member to vibrate such that vibrations are imparted to the body tissue in the body cavity of the human subject according to a vibration pattern, wherein the vibration pattern includes a main periodic element of a first frequency and an excitation stimulus of a second frequency higher than the first frequency.
