This application is a 35 U.S.C. 371 national stage filing from International Application No. PCT/IB2013/061206, filed Dec. 20, 2013, which claims priority to Italian Application No. MI2012A002236, filed Dec. 27, 2012, the teachings of which are incorporated herein by reference.
The present invention relates to an innovative vibrating system and to a method for corporeal stimulation.
In the literature various beneficial effects, both physical and psychological in nature, resulting from stimulation of the cutaneous mechanoreceptors by means of vibration are known. This type of stimulation is, however, somewhat difficult to perform in practice over the whole of the body, since the physical contact between the body and the conventional supports, such as chairs, couches or beds, interferes both with the production and the transmission of the suitable stimulating vibrations and the general sensations perceived by the user. In the first case, in fact, the fixed points defined by the body resting points are not stimulated and may on the contrary have a damping effect on the stimulations which it is attempted to produce in other parts of the body. In the second case, the sensation of contact on the supporting points (which generally cover an area much greater than the zones which can be stimulated by vibration using the known methods) generalizes the attention of the user and lessens, or even eliminates entirely, stimulation of the cutaneous mechanoreceptors to be produced by means of vibration, a large number of these mechanoreceptors being present only in certain well-defined parts of the body.
Some practical attempts to extend stimulation over the whole of the body have produced results which are random and not uniform.
US 2009/0139029 describes for example a bed with a device for producing vibration in sections of the bed. This produces generalized vibrations which cannot be properly controlled over the user's body.
U.S. Pat. No. 6,217,533 describes a generic vibrating device to be placed, for example, underneath the mattress of a bed, on a chair or underneath a cushion. The vibration effect is even more uncontrollable and dispersed.
These systems are not effective for being able to control in a suitable and precise manner the vibrations applied to the body.
In order for the vibration to provide effective stimulation it has in fact been found that it must be administered, depending on the mechanoreceptor to be stimulated, at a given frequency, at a precise amplitude, with a specific acceleration, for a given period of time and in well-defined zones. In fact, only these elements in combination are able ensure ideal activation of the cutaneous mechanoreceptors which are, as stated, sensitive only to a given set of parameters applied. However, the practical embodiments proposed hitherto do not allow full and precise adjustment of these parameters and the results obtained are therefore often limited.
Systems for suspending the body of a user in various ways have also been proposed.
However, they do not deal with the application of controlled vibrations, but only ensure a comfortable and relaxing support system. For example, WO2008/117330, WO2006/079327 and DE10353714 describe support devices on which a user may lie in such a way as to relax the muscles.
The general object of the present invention is to provide a vibrating system and a method which avoid the aforementioned problems and which allow more precise, extensive, variable and effective stimulation of the cutaneous mechanoreceptors by means of vibrations.
In view of this object, the idea which has occurred is to provide, according to the invention, a vibrating system for corporeal stimulation, comprising elements for supporting the user's body which are positioned so as to support separately the nuchal zone, dorsal zone, buttocks zone, hand zone, popliteal zone and heel zone, so as to keep the body supported only in these zones and in a semi-supine position, each support element, except in some cases the support element for the nuchal zone, being provided with a vibrating unit for transmitting to the body a controlled vibration upon emission of a programmed command from an electronic control unit.
The support elements are made of rigid material so as to allow perfect transmission of the signal wave.
Still according to the invention the idea has occurred to provide a method for producing localized vibrations in the body of a user for corporeal stimulation by means of vibrations, comprising suspending the user's body on supports only in the nuchal zone, dorso-lumbar zone, buttocks zone, hand zone, popliteal zone and heel zone, so as to keep the body supported in a semi-supine position and cause vibration of these supports upon operation, except in some cases the support in the nuchal zone, with a controlled vibration frequencies and amplitudes.
Advantageously, as will be clarified below, the support zones and the operating mechanisms are as follows:
In order to illustrate more clearly the innovative principles of the present invention and its advantages compared to the prior art, an example of embodiment applying these principles will be described below with the aid of the accompanying drawings. In the drawings;
With reference to the figures,
This system advantageously allows corporeal stimulation by means of proprioceptive resonance to be performed, as will be clarified below.
This system 10 comprises a structure 11 for supporting the body, which is provided with separate supporting elements which are positioned so as to support the nucha (element 12), the dorsal zone (understood as meaning the dorso-lumbar zone, element 13), buttocks (element 14), hands (elements 15), popliteal zone (elements 16) and the heels (elements 17).
All the elements of the structure are supported by a frame 18 resting on the ground which also maintains the relative position thereof. Advantageously, the frame provides support brackets for the support elements which can be suitably adjusted so as to ensure correct supporting of the aforementioned body zones also when there is a variation in the dimensions and proportions of the user's body. Advantageously, for example at least the longitudinal position of the support element for the heels and/or the support element for the popliteal zone may be adjusted.
In particular, a longitudinal bar or rail 19 may be provided for slidably supporting and fixing uprights 20, 21 for supporting, respectively, the support elements 16 for the knee pit and the support elements 17 for the heels. In this way, it is possible to adjust the horizontal distance of the elements 16 and 17 relative to each other and with respect to the seat formed by the elements 14. Similarly, means for adjusting, for example, the element 12 supporting the nucha may also be provided.
The semi-supine position assumed by the user's body is shown schematically in
The inclination of the body is such as to distribute the weight on the supports with almost complete relaxation of both the antagonistic muscles and the agonistic muscles.
Any muscular contraction is thus avoided and a better distribution of the arterial, venous and lymphatic circulation is permitted.
The structure described allows the body to be supported by means of ten predetermined contact points which correspond to precise articular joints. On the other hand, any contact in the area of the calf muscles, thighs, lumbar region, shoulders and cervical region is avoided, thus preventing any form of compression of the cutaneous and lymphatic circulation and the muscle masses.
Such a type of support structure is described (solely for relaxation purposes without any vibration or movement) in application WO2008/117330.
This type of support structure, however, has surprisingly been found to be suitable, together with innovative vibration systems, for providing a vibrating system for applying local vibrations to the supports which are located at different points and which have an effect on the whole of the user's body, as will be described below, with extremely surprising and unexpected results.
According to the principles of the invention, the support elements 13, 14, 15, 16, 17 are provided with suitable vibrating units connected to a central control unit 22.
The support element 12 for the nucha is instead advantageously of the passive type, namely without a vibrating device, so as to avoid stimulation in the vicinity of the cervical zone which may be bothersome.
Administration of the vibrations is performed at the ten points where the body makes contact with the ergonomic support structure. Essentially, these points correspond advantageously to the two palms of the hands, the right-hand and left-hand part of the curvature in the dorso-lumbar region, the popliteal fossae and the two Achilles tendon zones.
Preferably, audio headphones 23 are also provided, being connected to the control unit so as to receive from it audio signals, as will be explained below.
This control unit may be advantageously formed with a microprocessor system, known per se, suitably programmed for the operation of electric motors and for the emission of synchronous audio sounds, as will be explained below.
The control unit 22 may also comprise input means 24 such as, for example, a remote control unit 24 (cable or wireless) for selecting programs and functions of the system 10.
Advantageously, the various vibrating units have structures which are substantially identical to each other and are preferably oriented with their main axis longitudinal or transverse to the support structure, depending on the length of the plate of the support element and their position.
Preferably, each plate of the support elements is resiliently supported on the frame 18 (by means of suitable anti-vibration blocks made of resilient material) so as to be able to vibrate without transmitting the vibrations to the frame and thus prevent the formation of low-frequency harmonic waves. The corresponding vibrating unit is instead rigidly fixed to its plate and is advantageously provided internally with an electric motor which operates a suitable mass causing it to rotate eccentrically about the main axis of the unit.
In this way, the eccentric rotating mass imparts to the respective plate an alternating undulating vibration, the frequency of which depends on the speed of rotation of the motor, which is controlled by the control unit 22. The control unit, by controlling the angle and the direction of rotation of the motor forwards or backwards, may easily adjust the amplitude of the vibration within a wide range of values.
Advantageously, the motors of the vibrating units may be of the brushless type so as to have a low inertia and allow more rapid variations of the speed and the direction of rotation under the operational control of the control unit 22.
Moreover, for better control, each motor may comprise a suitable encoder for feedback control of its movement by the control unit 22.
The motors (which are advantageously low voltage) may be easily operated so as to produce vibrations of the vibrating units with a controlled amplitude and acceleration and a precise frequency, it thus being possible to obtain various operating programs for the system depending on the proprioceptive system which is to be stimulated and subjected to resonance.
Advantageously, the dorsal (or dorso-lumbar) support element is divided into two surfaces, i.e. right-hand surface and left-hand surface, independently vibrating by means of respective vibrating units 25 and 26. For reasons of elasticity and robustness, it has been found to be advantageous if the two surfaces are in any case formed with a single plate partially divided by a suitable incision in the middle.
As can be clearly seen in
In order to prevent possible breakage, the incision 29 advantageously terminates in a circular hole in the vicinity of the zone 30.
As can be seen again in
In the preferred structure shown here, the vibrating unit comprises a rigid housing 33 connected by means of screws 34 and 35 underneath the respective part 27. The housing, which is advantageously cylindrical, contains an electric motor 36, on the output shaft of which the eccentric mass 37 is mounted so as to rotate about an axis 38 which is substantially parallel to the plate 27 and to the longitudinal axis of the body.
Advantageously, a bearing supports the shaft on the opposite side of the rotating mass 37 in relation to the motor so as to prevent undesirable flexing of the shaft and ensure optimum control of the oscillation.

The housing, which is advantageously cylindrical, contains an electric motor 46, on the output shaft of which the eccentric mass 37 is mounted so as to rotate about an axis 48 which is substantially parallel to the plate and to the longitudinal axis of the body.
Advantageously, a bearing supports the shaft on the opposite side of the rotating mass 47 in relation to the motor so as to prevent undesirable flexing of the shaft.
Each vibrating unit 50 comprises advantageously a rigid housing 53 which is advantageously generally cylindrical and is connected by means of screws 54 and 55 underneath the respective plate 49 and contains the electric motor 56, on the output shaft of which the eccentric mass 57 is mounted so as to rotate about an axis 58 which is substantially parallel to the plate and transverse to the longitudinal axis of the body.
Advantageously, a bearing supports the shaft on the opposite side of the rotating mass 57 in relation to the motor so as to prevent undesirable flexing of the shaft.
As can be seen again in
With reference again to
Preferably, the support elements 15 for the hands are also (considered individually) similar to the single elements 16 or 17, except for the shape of their top plate (indicated by 69 in
The respective vibrating unit 70 is fixed underneath the plate 69, with the axis 78 of rotation of the vibrating mass which is directly parallel to the plate and transverse to the body.
It has been advantageously found that the speed of rotation of the eccentric masses usefully ranges between 1500 and 6000 rpm depending on the mechanoreceptor to be stimulated and the effect to be obtained therefrom. Furthermore, the single eccentric masses may advantageously have a weight which is between 10 and 25 grams and, preferably, about 15 to 18 grams (in particular about 17.23 g with an effective eccentric mass of about 15.47 g).
Advantageously, it has also been found to be preferable if the eccentric mass has a diameter of between 10 and 20 mm and preferably about 14 mm, with a rotation about an axis displaced by between 3 and 8 mm (and in particular about 4.5 mm) with respect to its geometric axis. The centre of the eccentric mass may be advantageously at between 4 and 7 mm (and in particular about 5.75 mm) from the geometric axis of the eccentric mass.
With the vibrating systems distributed in a support structure as described above it has been found that it is possible to apply programmed vibration cycles, the stimulation effect of which is transmitted—via the signal which the mechanoreceptors send to the central nervous system and back to the efferent zones (driving effect)—to the whole body and not only to small local zones corresponding to the support points. It has also been found that the specific structure of the vibrating units, together with their position and orientation, is surprisingly effective, despite its simplicity, preventing for example harmonic vibrations which would disturb the overall effect. It has also been found that this structure of the vibrating parts is advantageous for being able to implement vibration programs which may also be complex in nature and are preferably synchronized using exteroceptive proprioception with synchronized modulations and sounds transmitted via the headphones.
The proprioceptive stimulation performed by means of the system described produces an almost immediate effect, owing to self-resonance of the stimulated mechanoreceptors, without the interference and attenuation which would occur in the presence of other passive contact and support zones distributed underneath the user's body.
The strategic position of the plates supporting the body has been found to be most suitable for the action of multiple focal vibration which, via stimulation of the cutaneous mechanoreceptors by the driving effect, acts on several points of the muscle chains and other organs in the human body.
The structure according to the invention allows easy control of the frequency and, in particular of the acceleration ramps, this allowing, also by means of a vibration with a relatively small amplitude, a precise action at the predefined points without creating parasitic harmonic effects and without an invasive vibrating effect in the body structures.
Owing to the system described advantageously it has also been possible to obtain, without difficulty, frequency control of the vibrations within a range of between 15 and 150 Hz and, in particular, between 20 and 140 Hz, so as to obtain a wide range of stimulation effects. For example, depending on the prechosen program and depending on the objective to be achieved, it is possible to generate easily frequencies aimed at producing different stimulation reactions of the so-called Meissner's corpuscles with frequencies of between 20 and 60 Hz, depending on the desired objective, or also frequencies aimed at producing resonance of the so-called Pacinian corpuscles with frequencies of between 90 and 110 Hz, depending on the desired objective.
Moreover, various amplitudes of the vibrations (for example ranging from 1 to 4 mm) may be easily obtained so as to adapt to the desired stimulation effects (for example, in the region of 1.5 mm for stimulation of the Meissner's corpuscles and 2 mm for stimulation of the Pacinian corpuscles).
The structure according to the invention has also proved particularly suitable for controlling the acceleration ramps within a wide range of values. For example, the following ramps have been found to be useful: a ramp of 0 to 40 Hz in 2.5 seconds for initially adapting to the mechanical vibration of the Meissner's corpuscles, a ramp of 0 to 40 Hz in 0.5 seconds for activating the resonance of the Meissner mechanoreceptors, and a ramp of 0 to 90 Hz or 0 to 110 Hz in 0.4 seconds for activating the resonance of the Pacinian mechanoreceptors.
It should also be noted that, with a structure according to the invention, it is possible to act on the skin tissue, excluding the vibration effects in the deeper lying layers of the body, owing to the size of the motors and limited oscillation of the eccentric mass.
Since this vibration is distributed at the points which are most sensitive to proprioception, it may be regarded as being a specific global activator of the skin mechanoreceptors, without producing undesirable vibration effects in the inner lying body parts. The controlled area in which stressing is activated allows specific “activation” of various mechanoreceptors for different results.
The activation of these corpuscles has, for example, the property of stimulating cerebral zones and in particular neurons with high enteroceptive resonance, also called “mirror neurons”.
The most evident result, already obtained during the first session, in global stimulation of the Meissner mechanoreceptors, is total muscular repolarisation, i.e. complete relaxation of the muscles, perceived by the user as a general “floating” sensation. This “floating” effect immediately generates a strong sensation of pleasure and is not just a simulated effect, but is indicative of total separation from the bodily perception, due to inhibition of the synapse of the neuromuscular junctions.
Examples of the benefits which can be obtained with the system described and using the various operational possibilities associated with it are remodelling of the skeletal posture, psychological and physical relaxation, muscular relaxation, strengthening of the muscles, increase in muscle tone, relief from stress, increased creative abilities, improved sporting performance, post-performance relief, muscular decontraction, alleviation of back pain, reduction of articular pain, and improved lymphatic, venous and arterial circulation.
The control unit may contain in its memory various programs which can be selected using input means such as a remote control. Further programs may be stored as required, by means of suitable known data and program input interfaces (for example, SD card reader units, USB pens, etc.).
The programs stored in the control unit may for example each have a total duration of between 10 and 20 minutes and, in particular, between 12 and 15 minutes. The duration of the vibrations at given frequencies for a specific effect may be shorter than the entire program, for example with pauses between one vibration cycle at a certain frequency and another cycle, or with cycles at a certain frequency interspersed with other cycles at a different frequency for different effects.
It should be noted, however, that the benefits of the vibration have been found to be maximum when it is administered for a minimum duration of at least 8 minutes and, preferably, at least 10 minutes, but not longer than 20 minutes and preferably, not longer than 15 minutes, following which a tolerance reaction sets in.
Advantageously, the application of this method makes use of the overall involvement of proprioception including the exteroceptive stimulation of the hearing. The guiding voice and harmonic modulations synchronized with the vibrations favour abandonment to the therapy as a result of attenuation of the circular thought patterns and negative emotional states.
The sound recordings may be useful both for the treatment and for instructing the user during the various operational steps. The control unit may store sounds and voices (for example as audio files or as synthesized effects) which are then transmitted through the headphones depending on the program being run by the control unit and are usefully synchronized with the vibration program of the supports.
Advantageously, for one (or each) program, the control unit will have stored in one of its memories one or more tables with data relating to suitable acceleration ramps, times, amplitudes, frequencies, etc., associated with the particular program. During execution of the program, the control unit may thus simply retrieve in sequence at appropriate intervals this data in order to implement the entire programmed cycle.
In particular, for each motor the following may be programmed: the mechanical frequency which is to be produced, the amplitude at which the eccentric mass must rotate, the acceleration ramp which from zero reaches the desired frequency, and the duration of administration. The combined or separate action of the various motors is determined depending on the objective to be achieved (such as repolarisation, muscular strengthening, increase of muscle tone and the like).
Programming of the various parameters for execution of a specific program may be performed on a separate terminal (for example a personal computer) and then transferred to the control unit, or the remote control itself (suitably provided with an input and output interface) may be used, as may be now imagined by the person skilled in the art.
At this point it is clear how the predefined objects have been achieved. With the system and the method according to the invention, stimulation of the cutaneous mechanoreceptors with the consequent desired effects may be effectively applied in a highly precise and programmed manner.
Obviously the description above of an embodiment applying the innovative principles of the present invention is provided by way of example of these innovative principles and must therefore not be regarded as limiting the scope of the rights claimed herein.
For example, the system may be equipped with a more complex control and programming unit, or further motors and other user interfaces may be added. For example vibrating units applied to bandages on the stomach muscles, calf muscles, quadriceps, etc., may be used. In particular, in this way a further six motors with rotating masses may be added.
