Definitions

  • the present invention relates to the field of medicine and in particular to magnetotherapy of various diseases and disorders of human and other living beings.
  • the method according to the invention may be applied for therapy and prophylaxis of various diseases and disturbances.
  • the prior art discloses methods for therapeutic treatment of a human organism by means of magnetic field of high frequency electromagnetic oscillations producing a thermal effect /1/. These methods are commonly used in practice at physiotherapeutic rooms. However as they mainly use the heating effect so in some cases such methods may be counterindicated.
  • the prior art discloses methods for magnetotherapy consisting in treating various human organs by means of pulsed or variable low frequency magnetic filed while the choice of a specific magnet in the form of a catheter or solenoid, etc. depends upon the treated organ /2/. These methods provide local treatment of a specific organ but do not specify characteristics of such treatment.
  • the prior art discloses a magnetotherapy method /3/ for treatment of gynecological diseases wherein a biological object is irradiated by impulse magnetic low frequency field movable in time and space (similar to travelling wave) and being in coincidence with contraction of the cardiac muscle.
  • the apparatus for embodiment of the said method generates packets of pulse magnetic fields of direct current at the field generating rate per packet optimally coinciding with the cardiac contraction rate, and being synchronized with the latter, while the value of magnetic induction at each treated spot of the biological object varies from 0 up to maximum 40-60 mT sliding down to 0 again, representing thereby one of the most important therapeutic factors.
  • packets of pulse magnetic fields are discretely relocated for a distance corresponding to the interval between field axes within a packet.
  • the prior art also discloses a method /4/, similar to the said one, which is used for treatment of patients suffering from ischemic heart decease.
  • the method consists in synchronizing the travelling magnetic field to the cardiac cycle. Therapy under such methods generally is carried out in series for certain periods of time which duration is usually specified by a physician.
  • individual characteristics of an organ and an organism as a whole are not considered during the treatment procedure and thereby is lowered objectiveness of valuation of duration, number and frequency of sessions required for obtaining maximum favorable therapeutic effect.
  • the therapeutic effect may be negative.
  • the prior art discloses methods for measuring characteristics of biological organs, such as measurement of resistivity between two or more zones of a human body /5/.
  • the prior art also discloses methods for measuring impedance of biological tissues during exposure to magnetic field, e.g. a method for determining human resistance /6/.
  • This method allows to examine patients treated by magnetic field by way of measuring quasi-stationary potentials between the forehead and the hand, and by way of calculating the resistance gradient, but it does not allow to value state of health of certain organs.
  • an electromagnetic inductor of a specific shape which is predetermined by obtaining for the inductor maximum access to the selected organ, is positioned close by the organ, which organ is exposed during a certain period of time to pulse magnetic field at the impulse frequency of the magnetic field being harmonized with the biological cycle of the said organ, and in the course of the magnetotherapy procedure at least one characteristic of the tissue in the area of the said organ is measured.
  • the said method is characterized in that for a biological cycle determining the pulse frequency of magnetic field is selected a characteristic frequency response of the measured parameter to the effect of the magnetic pulse, and the therapy time is selected after obtaining a change of the measured parameter.
  • a measured parameter there may be taken any of thermometry, testing of electric impedance, tissue magnetic permeability, acoustic location or acoustic response to the magnetic effect in the area of the treated organ.
  • the method is further characterized in that the therapy session is administrated in two steps, the first preparatory step is administrated till obtaining the first change of the measured parameter, while the session is stopped at obtaining the next change of the measured parameter.
  • the first preparatory step is administrated till obtaining the first change of the measured parameter
  • the session is stopped at obtaining the next change of the measured parameter.
  • the first preparatory step is administrated up to obtaining a change of the first measured parameter, and at the further change of the other measured parameter the session is discontinued.
  • the field amplitude is gradually reduced in order to eliminate the possible depressing effect of overdosing magnetic field.
  • the frequency of pulse rate may be selected on basis of analysis of quasi- periodical signals.
  • the analysis may be made according to the technique disclosed in /7/.
  • FIG. 1 and 2 illustrate an example of the embodiment of the method under invention.
  • Figure 1 shows a diagram of therapy and changes of parameters obtained in the course of treatment of prostate diseases.
  • Figure 2 represents a graph showing changes of the detector signal according to the [Example.
  • the organ under treatment is effected by pulse packets of magnetic filed and the packet frequency rate is adjusted with one of the biological cycles (cardiac rhythm, alpha rhythm, etc.), usually at the range 1 to 10 Hz.
  • the pulse repetition rate in the packet is selected on the bases of the measured parameter response of the organ under treatment (usually about 100Hz and above).
  • the measured signal is examined and the magnetic field amplitude is settled at the level of absence of treatment sensations (which are of the reflex nature).
  • sensations of integral character such as an orgasm during genitals therapy.
  • the present embodiment of the method uses fields at the induction 1 -10 mT producing no physiological or reflex effect but having only a stimulating effect.
  • At least one parameter is measured, and namely the parameter which is able to indicate changes happening in organ tissues.
  • the parameter which is able to indicate changes happening in organ tissues.
  • resistivity or impedance of organ tissues or tissues located immediately around it Totally this may be a temperature of an organ, though this parameter is one of the most inertial ones.
  • the most preferable parameter for measurement is registration of tissue magnetic permeability. Any of this measurements may be preformed either by means of a special detector or by a detector combined with an inductor. Studies demonstrated that therapy by magnetic field stimulates biological processes in tissues, and this is revealed in changes of electromagnetic and other parameters of organ tissues subjected to treatment. Thus, as during therapy this parameter changes, so said change allows to determine duration and intensity of the therapeutic session.
  • the first step is aimed at overcoming inertia of organ state or pathology, and the process of stimulation or normalization is expediently carried out in a more 'soft" mode. Therefore the amplitude of magnetic filed may be reduced immediately in the therapy process, especially as the subliminal treatment during stimulation is more effective and produces no side effects.
  • Measured parameters may be valuated by computer analysis of quasi- periodical signals or by the specially reserved processor. On the basis of this analysis it is possible to select parameters for therapeutic effect, such as frequency of pulse packets and pulse repetition per packet, amplitude and session duration for each step.
  • the value of the resistivity characteristic of the tissue in the area of the treated organ is measured by a detecting element made in the form of a catheter on which an even number of conductive rings is arranged, said rings are connected to commutating, registrating and analyzing devices.
  • the detector (1) is introduced through urethral canal and positioned in the immediate contact with the prostate (2).
  • the therapeutic magnetic inductor (3) (introduced rectally) is positioned in such a way that the magnetic field is directed towards prostate.
  • a change of prostate conductivity in the periods between separate impulses of therapeutic magnetic field is registered by the detector.
  • the active (resistive) and the reactive components of organ conductivity undergo changes, so variable is the value of the signal coming from the detector to the signal analyzer or to the computer.
  • Figure 2 illustrates signal variations of such a detector. Clinical tests showed that the absolute value of conductivity signals may lie within a broad dynamic range depending upon individual features and specific state of a patient.
  • the signal value may gradually vary either up or down to the absolute value. However at a certain moment the majority of patients (about 80%) demonstrate a sharp change of signal strength (section A) which change constitutes about 30% of signal strength and is easily registered by the signal analyzer. This is applied to provide individual dosing during the magnetotherapy process.
  • the signal value is stabilized in the course of further treatment by magnetic filed but at the certain moment the second signal change takes place which is also registered by the analyzer. The said second change may be identified with the beginning of the normal organ functioning.
  • An extremely sustained treatment procedure may cause degradation of the stimulating effect and change intensity of biochemical processes, and on further continued exposure to magnetic field even depression may develop. Therefore it is desirable to discontinue the therapeutic treatment by magnetic filed at the onset of normal organ functioning or in the short period after the beginning of the said functioning, which may be traced by the second change of the measured parameter.
  • the first step may be determined by one of the parameters, and the end of the second step - by the second measured parameter.
  • the criterion for determining duration of the second period may be used external demonstration of the organ functioning. Thus, recovery of erection may serve as the criterion for the described example.
  • Magnetic field parameters are selected on the basis of computer analysis of quasi-periodical signals, e.g. as disclosed in /7/.

Abstract

La présente invention concerne le domaine de la médecine et plus particulièrement la magnétothérapie par impulsion appliquée à des objets biologiques. Une modification d'un paramètre mesuré permet de déterminer, individuellement pour chaque patient, le moment où il convient d'administrer le traitement. La mesure d'un paramètre peut être associée conjointement ou séparément à des valeurs de paramètres physiques, par exemple, l'impédance, la perméabilité magnétique, la température, un paramètre acoustique. La fréquence d'impulsion du champ magnétique est harmonisée avec un cycle biologique de l'organe (2) traité.
