Abstract

Data defining electrical waveforms for physical therapy is created on a computer and stored in a removable machine-readable medium such as a CD-ROM or semiconductor memory module. The data is played back, for example on a portable CD-ROM player, to produce the physical therapy waveforms at any time and location convenient or desired by the patient. An interface circuit amplifies and conditions the resulting waveforms for applying them to the skin of the patient via leads and electrodes. Since most therapies use waveforms within the audio frequency range, ubiquitous low-cost audio playback equipment can be used. Advantages of the invention are providing physical therapy at any location and at low cost, without requiring presence of a clinician or other health care professional on location.

Claims

1. Apparatus for administering electrical physical therapy to a patient, comprising:

an audio playback device adapted to play prerecorded audio signals;

an interface circuit connectable to receive and amplify the audio signals;

at least two electrodes adapted to directly apply the amplified audio signals to skin of the patient; and

a lead for interconnecting each of the at least two electrodes to the interface circuit to convey a corresponding amplified audio signal to a respective of one of the electrodes.

2. Apparatus according to claim 1 wherein the prerecorded audio signals comprises at least two interferential audio frequency analog signals stored on a machine-readable medium.

3. Apparatus according to claim 2 wherein the machine-readable medium consists of magnetic tape.

4. Apparatus according to claim 1 wherein the prerecorded audio signals comprises digital data defining one or more audio frequency analog signals, stored on a machine-readable medium.

5. Apparatus according to claim 4 wherein the machine-readable medium consists of random access memory.

6. Apparatus according to claim 4 wherein the machine-readable medium consists of a CD-ROM.

7. Apparatus according to claim 4 wherein the machine-readable medium consists of semiconductor memory.

8. Apparatus according to claim 4 wherein the machine-readable medium consists of a PCM-CIA card memory.

9. Apparatus according to claim 1 wherein the audio playback device comprises a portable audio playback device.

10. Apparatus according to claim 9 wherein the audio playback device comprises a portable CD-ROM player.

11. Apparatus according to claim 9 wherein the audio playback device comprises a computer.

12. Apparatus according to any of claims 1-8 wherein the interface circuit includes an input jack connectable to an audio output jack of the audio playback device to receive the audio signals.

13. Apparatus according to claim 1 wherein the prerecorded audio signals comprise digital data defining one or more audio frequency analog signals, stored on a machine-readable medium, and the analog signals form a selected physical therapy modality.

14. Apparatus according to claim 13 wherein the selected physical therapy modality comprises at least one of interferential, low and/or high voltage galvanic, muscle stimulation, micro-current, Russian stimulation, transcutaneous electrical nerve stimulation (T.E.N.S.), Faradic, and synaptic electronic activation therapy modalities.

15. Apparatus according to claim 1 wherein the prerecorded audio signals comprise digital data defining two or more physical therapy modalities, the data defining each modality stored on a respective track of a machine-readable medium, thereby allowing the patient to receive a selected one of the physical therapy modalities by playing the corresponding track on the audio playback device.

32. Apparatus according to claim 1 wherein the prerecorded audio signals are downloadable via an internet connection.

16. A system for prescribing an electrical physical therapy treatment, comprising:

a computer having a display and input means for receiving input from a user to allow the user to define a physical therapy treatment; and

storage means connected to the computer for storing audio signals representing the defined physical therapy treatment onto a removable, machine-readable media, thereby allowing delivery of the defined physical therapy treatment directly to a patient in a convenient, portable form by delivering the removable media to the patient.

17. A system according to claim 16 wherein the audio signals representing the defined physical therapy treatment comprises at least one audio frequency waveform.

18. A system according to claim 16 wherein the audio signals representing the defined physical therapy treatment comprises digital data representing at least one audio frequency waveform.

20. A system according to claim 17 wherein the input means for receiving input from a user allows the user to select a frequency and an amplitude of said at least one audio frequency waveform.

21. A system according to claim 16 wherein the storage means includes means for storing the data onto a writable CD-ROM.

22. A system according to claim 16 wherein the storage means includes means for storing the data into a semiconductor memory.

23. A system according to claim 16 wherein the storage means includes means for storing the data onto a magnetic recording tape.

24. A system according to claim 16 wherein the storage means includes means for downloading the data from a remote location.

25. A method of prescribing and delivering electrical physical therapy to the body of a patient, comprising:

selecting a physical therapy treatment modality in terms of one or more audio frequency waveforms having selected amplitudes and frequencies;

recording the audio frequency waveforms on a machine-readable recording medium;

reading the audio frequency waveforms from the recording medium using an audio playback device to form audio frequency signals;

amplifying the audio frequency signals; and

applying the amplified audio frequency signals directly to the body of the patient thereby delivering the selected physical therapy treatment modality to the patient.

26. A method according to claim 25 wherein the recording comprises recording the audio frequency waveforms as digital data.

27. A method according to claim 26 wherein said recording medium consists of semiconductor memory.

28. A method according to claim 26 wherein said recording medium consists of a CD-ROM.

29. A method according to claim 26 wherein the amplifying includes increasing a voltage of the audio frequency signals.

30. A method according to claim 26 wherein the amplifying includes isolating the audio frequency signals from the amplified audio frequency patient.

31. A method according to claim 26 wherein the amplifying includes limiting a voltage of the amplified audio frequency signals.
