Abstract

A method and apparatus for therapeutic treatment wherein pulsed, alternating current, electrical signals are applied to an applicator coil adjacent an area to be treated to produce multi-rhythmic, pulsed, alternating magnetic fields which have a therapeutic effect on the treated area. The frequency of the magnetic fields is in the range 0.5 Hz to 25 Hz and the waveform includes higher harmonics to approximate natural waveforms measured in the body, such as by an EEG.

Claims

1. An apparatus for therapeutic treatment comprising:

a generator unit for providing alternating current;

a control means, in electrical connection with said generator unit, for receiving as input alternating current from the generator unit and for providing electrical signals as output;

said electrical signals being multi-rhythmic pulsed alternating signals at a frequency in a range of 0.5 Hz to 25 Hz; and

one or more applicator coils, in electrical connection with said control means, for converting the electrical signals to magnetic fields.

2. The apparatus of claim 1 wherein the generator unit includes a step-down transformer for converting a primary alternating current voltage source to a secondary alternating current voltage source wherein the secondary alternating current voltage source has a voltage in a range of 15 volts to 50 volts.

3. The apparatus of claim 1 wherein the generator unit includes a step-down transformer for converting a primary alternating current voltage source to a secondary alternating current voltage source wherein the secondary alternating current voltage source has a voltage of 18 volts.

4. The apparatus of claim 1 wherein the generator unit includes a step-up transformer and DC to AC inverter circuit for, in combination, converting a direct current voltage source to an alternating current voltage source with a voltage in a range of 15 volts to 50 volts and a frequency of either 50 Hz or 60 Hz.

5. The apparatus of claim 1 wherein the generator unit includes a step-up transformer and DC to AC inverter circuit for, in combination, converting a direct current voltage source to an alternating current voltage source with a voltage of 18 volts and a frequency of 50 Hz.

6. The apparatus of claim 1 wherein the control means comprises a microprocessor and a triac, wherein the microprocessor provides signals to control the operation of the triac and the control means further comprises an arrangement of resistors and capacitors in electrical connection with the triac for converting alternating current to multi-rhythmic pulsed alternating electrical signals.

7. The apparatus of claim 1 further comprising display means for displaying operating parameters of the apparatus.

8. The apparatus of claim 1 wherein the applicator coils are of wire-wound construction.

9. The apparatus of claim 1 wherein the electrical signals approximate natural waveforms found in the human body.

10. A method of therapeutic treatment including the steps of:

locating one or more applicator coils adjacent an area to be treated;

applying electrical signals having frequency, amplitude and pulse characteristics to said applicator coils so as to produce multi-rhythmic, pulsed, alternating magnetic fields in a vicinity of the coils; and

adjusting the frequency, amplitude and pulse characteristics so as to produce a pulsating magnetic field having therapeutic effect in the area to be treated.

11. The method of claim 10 wherein the step of applying electrical signals includes applying signals with a frequency of 0.5 Hz for a time period between zero minutes and thirty minutes.

12. The method of claim 10 wherein the step of applying electrical signals includes applying a sequence of signals, said sequence comprising applying signals having a 2 Hz frequency for 30 seconds followed by signals having a 4 Hz frequency for 60 seconds followed by having a 8 Hz frequency for 90 seconds followed by having a 12 Hz frequency for 120 seconds and repeating said sequence four times for a total treatment time of 20 minutes.

13. The method of claim 10 wherein the step of adjusting the frequency, amplitude and pulse characteristics includes programming a microprocessor to automatically adjust the frequency, amplitude and pulse characteristics.

14. The method of claim 10 wherein the step of applying electrical signals includes repetitively applying at intervals a chosen treatment until manually stopped.

15. The apparatus of claim 10 wherein the electrical signals approximate natural waveforms found in the human body.

16. A method of therapeutic treatment including the steps of:

locating one or more applicator coils adjacent an area to be treated;

applying electrical signals having frequency, amplitude and pulse characteristics to said applicator coils so as to produce multi-rhythmic, pulsed, alternating magnetic fields in a vicinity of the coils, wherein the step of applying electrical signals includes applying a sequence of signals, said sequence comprising applying signals having a 2 Hz frequency for 30 seconds followed by signals having a 4 Hz frequency for 60 seconds followed by having a 8 Hz frequency for 90 seconds followed by having a 12 Hz frequency for 120 seconds and repeating said sequence a plurality of times; and
