Vibration pattern for vibration stimulation

A method of treatment of a human subject, comprising the steps of:

• introducing a stimulation member into a nasal cavity of a human subject, said stimulation member being adapted to impart vibrations to body tissue of the human subject;
• anchoring the stimulation member to the head of the human subject by means of at least one of a head band, a facial mask, a pair of glasses, and a helmet;
• selecting a first frequency by:
• imparting vibrations to said nasal cavity at a variable frequency;
• gradually adjusting the variable frequency up to a maximum frequency;
• monitoring a bodily response to the treatment, the bodily response being indicative of a physiological condition of the subject;
• determining the first frequency based on the monitored bodily response;
• and
• imparting vibrations to the nasal cavity of the human subject according to a vibration pattern,
• wherein the vibration pattern comprises a main periodic element with the first frequency and an excitation stimulus with a second frequency higher than the first frequency, and the second frequency is within a range of 1.5-5 times as high as the first frequency,
• wherein the vibrations are generated by one or more of:
• an electroactive material, wherein the stimulation member comprises said electroactive material, the electroactive material being controlled such that the stimulation member vibrates according to the vibration pattern;
• and
• a vibration generator comprising a frequency regulating module configured to provide vibrations according to the vibration pattern to a pressurized fluid in the stimulation member, and
• wherein the step of monitoring a bodily response further comprises one or more of the steps of measuring a bodily response selected from a list comprising:
• nasal secretion, sneeze frequency, pain sensation, pupil size.
