  • the invention relates to equipment and a method for alleviating and/or eliminating both strain or chronic tension of the muscles and acute or chronic pain and soreness of varying degrees by means of infrasonic massage.
  • the equipment provides sound massage by emitting infrasonic waves (1-16 Hz) and other low frequency (over 16-50 Hz) soundwaves and frequencies that are higher than 50 Hz.
  • the effect of the equipment is enhanced by heat elements, in which vibrator parts are inserted.
  • the heat elements improve the result of the infrasonic massage.
  • the effect of the equipment is based on scientific research conducted by various scientists in different universities and institutes. In US 4,538,596, David A. Colasante states that low-frequency sound energy triggers a relaxation response in man.
  • the relaxation response appears either as a decrease in muscle tension or a drop in the breathing rate or in the heart rate per minute, or as all of these.
  • Johnson, Hensel and Matheson state that vibration therapy has a statistically significant effect on relaxation. In their study, they used an acoustophysicai chair, supplying 37 Hz to the legs of the chair and 47 Hz to the back. The measurements were carried out by the E G method. The study is described in "Vibration effects on three measures of relaxation" in Perceptual and Motor Skills, 1985, 54, 1071-1076, summary, University of the Pacific. Further, in the summary of "Changes in wakefulness during exposure to whole body vibration" in Electroencephalography and Clinical Neurophysiology, 1985, 61 , p.
  • the low-frequency vibration is stated to alleviate or eliminate both acute and chronic pain and soreness efficiently.
  • the pain barrier has been stated to rise and the pain to be alleviated in about or over 50% of the cases, and the duration of the effect has been satisfactory. As a rule, the effect has been greater in acute cases than in chronic ones.
  • T.C. Lundeberg in "Vibratory stimulation for the alleviation of chronic pain" in Ada Physiologica Scandinavica, Supplementum, 523: 1-51 abstract, 1983.
  • the study was conducted on 731 persons, 135 of which suffered from acute pain and 596 from chronic pain. Vibration therapy was given at a moderate pressure, the selected vibrations were 50-100 Hz and lasted a maximum of 30-45 min.
  • the study also included a comparison between low-frequency (20 Hz) and higher frequency (100 and 200 Hz) and placebo vibration.
  • the result was that about 50% of the study subjects reported the vibration treatment to have a positive effect with the original settings of the test.
  • the pain barrier was observed to rise and the pain to be alleviated in over 50% of the cases, and in the case of more severe pain, in less than 50% of the cases.
  • the study also revealed positive correlation between the degree of pain and the absence of pain. Lundeberg has conducted or been involved in many studies that deal with correlation and interaction between vibration treatment and alleviation of pain. He has observed that vibration also has a positive effect in the long run.
  • One of the studies dealing with the long-term effects is "Long-term results stimulation as a pain relieving measure for chronic pain" in Pain 20 (1): 13-23 abstract 1964 sep. The institute involved in these studies has often been Karolinska Institutet, Sweden.
  • the low-frequency vibration has a positive effect on relaxation and alleviation of pain and soreness
  • the present equipment is smaller, and it is simpler to use.
  • the equipment can be used independently of the time, place, assisting persons and massaging position.
  • the fastening means of the equipment are such that the same equipment fits as many different people as possible, so that the method can be used widely. Because of the flexibility of the fastening means, the same fastening means also fit different parts of the body.
  • the present invention is based on the use of infrasonic vibration. So far, the attempts to focus infrasound directly on the point to be massaged have not been successful.
  • the infrasounds are generated using piezo buzzers or other such sound sources emitting about 400 Hz sound.
  • the sound of the piezo buzzers is modulated and swept. This produces the part comprising a low-frequency sound component to the point being massaged.
  • the modulation takes place at low frequencies, and the modulation frequency can be adjusted.
  • As a by-product, interference is also produced.
  • the produced modulated sound and sound sweep are supplied from the vibrator part to the point that is being massaged.
  • the heat element facilitates the focusing of the vibrator part or parts and improves the massaging result due to its insulating effect.
  • the heat elements do not receive heat from any separate source or any source external of the body.
  • the equipment comprises three main components: a control unit; a vibrator part, the number of which can vary but in this embodiment is at most two; and a heat element, the number of which can also vary; and connecting cables between the main components.
  • the control unit comprises the components needed to control the massage equipment, and the modulation and sweep circuitry.
  • the vibrator part/parts are connected to the control unit with a connecting cable.
  • the heat element/elements need not be used, but they facilitate the focusing of the massage and improve the result.
  • the heat elements have been made detachable, since heat is not suited to everyone, for example not to patients with rheumatism.
  • heat elements are used, they are integrated in the same physical entity by inserting the vibrator part in the heat element's pocket.
  • vibration treatment Many kinds of therapy and massage apparatuses based on vibration treatment are previously known, and so the technology involved also varies. When a comparison is made, one must pay attention to the type of vibration produced, the vibration frequency, the way that the vibration penetrates the point of treatment/massage, and whether the vibration is supplied directly or indirectly. In the indirect method, for example, the focusing of the treatment does not produce as good results as in the direct method.
  • the vibration can be produced, for example, by using electromagnetic, mechanical, pneumatic, hydraulic and sound vibration. In the present invention, modulated and swept sound is used by means of piezo buzzers. The vibration can also vary within a certain frequency range. Also, different applications are differently independent of the place, time, massaging position and assisting persons, particularly where self-treatment is concerned. We shall also compare the invention with the publications in these respects, wherever the publications provide sufficient information.
  • US 4,343,303 discloses an apparatus designed to focus vibration treatment on certain parts of the body, such as the neck, head, back and waist regions.
  • the apparatus can be provided with a vibrator or, preferably, two vibrators arranged on each side. Instead, the vibration type and the frequency used in the apparatus are not mentioned.
  • the power source producing the vibration is a battery attached to the apparatus.
  • the apparatuses are preferably coated with plastic, and the material on the inside is soft material suitable for the body. All the controls are contained in the apparatus that will be attached to the body.
  • the integrated system is rather heavy and cannot be changed easily.
  • the source of vibration we have accurately defined the source of vibration, the vibration frequency and the type of vibration.
  • the heat element is flexible throughout: it does not comprise hard plastic that would inhibit the use of the same element in different parts of the body, such as the arm, leg, back, side, neck, etc.
  • the range of use of one and the same element is thus essentially wider in the present invention than in the above patent publication.
  • the energy we use is sound modulated and swept by piezo buzzers, so the present arrangement differs essentially from the apparatus disclosed in the publication.
  • the apparatus (apparatuses) of US 4,979,502 is also designed to focus vibration treatment on certain parts of the body, but it also contains a vibrator and adjustable heat.
  • the power source of the apparatus is a battery.
  • the vibration and heat are controlled manually. Different versions of the apparatus are described: for example, apparatuses for the upper part of the body, the back, waist, head and the legs.
  • the publication does not state the type of vibration, nor the frequency (Hz), although it is mentioned that the vibration can be adjusted.
  • the heat is generated by means of batteries in specific heat resistors. Since batteries, heat resistors, slots for vibrator parts, room for vibrators, controls, etc. are arranged in the apparatus, and since the apparatus is hard on the outside, the apparatus with the integrated structure is rather heavy and therefore not as versatile as the present invention.
  • heat is not generated separately for the heat element from any source.
  • the heat element does not comprise any controls or batteries.
  • the heat element of the present invention simply insulates heat, and one of its functions is to focus the massage on exactly the correct point.

  • the structure of the apparatuses disclosed in the patent publication is such that they cannot be readily modified for other parts of the body.
  • the vibration type is defined, and so are the quality and frequency of the vibration.
  • US 3,053,250 discloses a coat-shaped apparatus comprising several fastening points, tightening belts, and slots for other components, for example, for vibrators and controls, and so the coat is rather heavy, since a large number of components have been integrated therein. Sound energy is not recommended, whereas electric and mechanical vibration are.
  • the publication does not state the vibration frequency used.
  • the present invention uses modulated and swept soundwaves, the sound graph of the modulated sound being defined accurately at a certain modulation and sweep frequency, i.e. different energy is used.
  • the heat elements are also flexible in many respects: the same heat element is suited to different parts of the body and to people of different sizes. Further, the heat elements of the invention are neither large nor heavy, extending from the shoulders to the waist at the front and back of the body and thereby hampering the movements.
  • the massage equipment using infrasound is thus also suited to self-treatment. On account of the above, and since modulated sound and a sound sweep technique are used in the present massage equipment, the equipment is different from the apparatus/apparatuses disclosed in the above patent publication.

  • the apparatus is large, and it comprises as integrated parts a vibrator or vibrators, a control system, fastening means, energy sources, etc., so it cannot be readily used for the other parts of the body than the upper part, i.e. chest and back, for which it has been designed.
  • the frequency of the vibration to be used is not defined.
  • the material of the apparatus varies from synthetic to natural material, but the apparatus is rather large and heavy.
  • the equipment of the present invention is based on the use of modulated and swept soundwaves by sound heads and through a vibrator part, i.e. the energy form and technology are different.
  • the modulation frequency can be selected quite accurately, even by the figure (Figs. 4 and 5) or the effect.
  • the heat elements help to focus the massage.
  • the heat elements are versatile because of their adhesive tapes and straps. They are suitable for different people and for different parts of the body, so a minimal number of heat elements are needed. They help to focus the massage and also provide thermal insulation.
  • the only component integrated in the heat element is the vibrator part, so the lightness and versatility of the heat element are different from the above patent publication (Harness).

Abstract

L'invention concerne un appareil de massage destiné à atténuer ou à éliminer les tensions musculaires aiguës ou chroniques, ainsi que les douleurs, par l'utilisation d'un infrason généré par modulation et balayage de la sortie de transducteurs piézo-électriques ou similaires. L'invention est basée sur de nombreuses études scientifiques et leurs résultats. Le son modulé comprend un composant infrasonore de 1 à 16 Hz et d'autres fréquences kilométriques, ainsi que quelques fréquences plus élevées. La sortie est analysée et les fréquences obtenues sont représentées par des graphes (figures 4 et 5). Cette nouvelle approche a permis de fabriquer ce nouvel appareil de massage utilisant les vibrations sonores. L'appareil étant souple et petit, le massage peut être indépendant du temps, du lieu, de la position du corps et du personnel auxiliaire. Par ces propriétés, il est également idéal pour l'auto-traitement. Les éléments chauffants aident à concentrer le massage au bon endroit, c'est-à-dire sur la partie ayant besoin d'être traitée. Les revendications du brevet concernent l'appareil de massage (produisant un son modulé) en tant que tout, ainsi que ses différentes parties.
