Method and arrangement for alleviating the stress-related sleep disorder and reducing the stress level of a person

A method for reducing a person's stress by applying low frequency vibration to person's body or to at least one part of the body with an apparatus which includes a plate type base member capable of having brought to contact therewith mechanical vibrators by which said base member can be set in vibration, said method comprising

• A) detecting a person's stress level by assessing or measuring,
• B) using mechanical vibrators present on a first side of the apparatus' plate type base member for setting the plate type base member in vibration in such a way that one of its surfaces transmits mechanical vibration, comprising a plurality of low frequency (pressure) pulse trains which are conducted to the person's body or selected body part, wherein successive mechanical vibration pulse trains to be transmitted to the body or a selected part of the body comprise
• a first vibration component, which consists of a plurality of first successive pulse trains or vibration cycles transmitted at successive time periods to the body or a selected part of the body, each of said pulse trains having a duration of several minutes and a frequency of the vibration being constant within the range of 20-50 Hz through said duration of the pulse train, while (pressure) pulses of the vibration are at same time adapted to be such that the pressure pulses included in each pulse train have a contact power with the body or said body part within the range of 40-70 dB, whereby the constant frequencies of the successive pulse trains are mutually different and change monotonously and mostly linearly when proceeding from a first vibration cycle to a second one;
• and further
• a second vibration component, which consists of at least one second pulse train or second vibration cycle transmitted to the body or a selected part of the body, wherein the pressure pulses included in the pulse train have a frequency fluctuating within the range of 20-50 Hz, preferably within the range of 20-40 Hz, over the course of 2-10 seconds, preferably over the course of 5-7 seconds (frequency-modulated vibration cycle), and said frequency change of the pressure pulses occurs in accordance with sine, triangle or square wave,
• C) detecting a stress level and deciding, on the basis of the measured or detected stress level, whether the treatment is continued again from step A.

An arrangement for alleviating a person's stress-related sleep disorder, especially for alleviating stress-related transient adjustment insomnia with an apparatus which comprises a plurality of vibrator elements, mounted on the apparatus' one or more solid or flexible resonatable base members and being capable of converting an electrical impulse into a pulse of mechanical vibration, as well as a data processing unit with a capability of producing a control instruction for setting up an electrical impulse train by using the mechanical vibrators present on a first side of the apparatus, i.e. on an opposite side of the base member with respect to the person's body, for setting the base member to vibrate in resonance with said mechanical vibrators in such a way that the base member's second surface, which is opposite to said first side and closer to the person's body, transmits to the body or to a selected part of the body low frequency mechanical vibration consisting of successive pressure pulses of mechanical vibration, wherein the pressure pulses make up

• a first vibration component, which comprises a plurality of successive soothing vibration cycles transmitted to the body or said part of the body at successive time periods, which comprises low frequency successive pressure pulses, each pulse train of which has a duration of several minutes and a vibration frequency which is constant within the range of 20-50 Hz through said duration of the pulse train, while the (pressure) pulses of the vibration are at the same time adapted to be such that the pressure pulses included in each pulse train have a contact power (I) with said body part within the range of 40-70 dB, and
• a second vibration component, which is transmitted thereafter to the body or to said part of the body and which comprises at least one second massaging vibration cycle, the pressure pulses included in said one second vibration component having a frequency (f) fluctuating within the range of 20-50 Hz, over the course of 2-10 seconds, and said frequency of the pressure pulses changes in accordance with sine, triangle or square wave.

A piece of software installed in a data processing unit and adapted to generate by means of a central processing unit, as a control instruction, a signal pulse train with a capability of generating a plurality of low frequency pulse trains, said pulse trains of mechanical vibration comprising

• a first vibration component, which consists of a plurality of first successive pulse trains or vibration cycles transmitted at successive time periods to said part of the body, each of said pulse trains having a duration of several minutes and a frequency of the vibration being constant within the range of 20-50 Hz through said duration of the pulse train, while the vibration is at the same time adapted to be such that pressure pulses included in each pulse train have a contact power (I) with the body or the selected body part within the range of 40-70 dB, whereby the constant frequencies of the successive pulse trains are mutually different and change monotonously and mostly linearly when proceeding from a first vibration cycle to a second one;
