Abstract

A system for delivering more than one energy waveform to a patient. The system comprising a first pair of electrodes and a second pair of electrodes adapted to be positioned on the patient and adapted to deliver energy to the patient, a stimulation pad comprising the first pair of electrodes and the second pair of electrodes, and a stimulation control unit in communication with the first and second pairs of electrodes. The stimulation control unit configured to combine a first energy waveform having a first frequency and a second energy waveform having a second frequency into a multiplexed signal, and deliver the multiplexed signal to the first pair of electrodes and the second pair of electrodes.

Claims (35)

1. A system for delivering more than one energy waveform to a patient, comprising:

a first pair of electrodes and a second pair of electrodes adapted to be positioned on the patient and adapted to deliver energy to the patient;

a stimulation pad comprising the first pair of electrodes and the second pair of electrodes; and

a stimulation control unit in communication with the first and second pairs of electrodes and configured to:

combine a first energy waveform having a first frequency and a second energy waveform having a second frequency into a multiplexed signal; and

deliver the multiplexed signal to the first pair of electrodes and the second pair of electrodes.

2. The system of claim 1 , further comprising an impedance modification element configured to be positioned apart from at least one of the first pair of electrodes and the second pair of electrodes.

3. The system of claim 2 , wherein the impedance modification element comprises a cooling element adapted to decrease the temperature of tissue within the patient to thereby increase impedance of tissue within the patient.

4. The system of claim 1 , wherein the first energy waveform is a pain-relieving energy waveform and the second energy waveform is a muscle-activating energy waveform.

5. The system of claim 4 , wherein the first energy waveform comprises a first set of pulses and the second energy waveform comprises a second set of pulses, wherein the first set of pulses have a lower amplitude and a higher frequency than the second set of pulses.

6. The system of claim 1 , wherein the first energy waveform and the second energy waveform are generated by the stimulation control unit.

7. The system of claim 1 , wherein the first frequency is different than the second frequency.

8. The system of claim 1 , further comprising a housing, wherein the housing comprises the first pair of electrodes, the second pair of electrodes, and the stimulation control unit.

9. The system of claim 1 , wherein the multiplexed signal is delivered to the first and second pairs of electrodes simultaneously.

10. A system for delivering more than one energy waveform to a patient, comprising:

a first set of electrodes and a second set of electrodes adapted to be positioned on the patient and adapted to deliver energy to the patient;

a stimulation pad comprising the first set of electrodes and the second set of electrodes; and

a stimulation control unit in communication with the first and second sets of electrodes and configured to:

generate a first energy waveform having a first frequency and a second energy waveform having a second frequency; and

deliver the first energy waveform and the second energy waveform to the first and second sets of electrodes.

11. The system of claim 10 , further comprising an impedance modification element adapted to increase impedance of tissue within the patient, wherein the impedance modification element is further adapted to increase neuromuscular electrical stimulation by reducing lateral energy spread between the first and second sets of electrodes.

12. The system of claim 11 , wherein the impedance modification element comprises a cooling element and is configured to be positioned apart from the first and second sets of electrodes.

13. The system of claim 10 , wherein the first energy waveform is a pain-relieving energy waveform and the second energy waveform is a muscle-activating energy waveform.

14. The system of claim 10 , wherein the first energy waveform comprises a first set of pulses and the second energy waveform comprises a second set of pulses, wherein the first set of pulses have a lower amplitude and a higher frequency than the second set of pulses.

15. The system of claim 10 , wherein the first frequency is different than the second frequency.

16. The system of claim 10 , wherein the first energy waveform is delivered from the stimulation control unit to the first set of electrodes and the second energy waveform is delivered from the stimulation control unit to the second set of electrodes.

17. The system of claim 10 , wherein the first energy waveform and the second energy waveform are delivered to the first and second sets of electrodes simultaneously.

18. A system for delivering more than one type of energy waveform to a patient, comprising:

a stimulation control unit configured to generate a first energy waveform having a first frequency and a second energy waveform having a second frequency; and

a first pair of electrodes and a second pair of electrodes; and

a stimulation pad comprising the first pair of electrodes and the second pair of electrodes, wherein the first pair of electrodes and the second pair of electrodes are in communication with the stimulation control unit, the first and second pairs of electrodes adapted to be positioned on the patient and adapted to deliver energy to the patient, wherein the first and second pairs of electrodes are configured to:

receive the first energy waveform and the second energy waveform from the stimulation control unit; and

combine the first energy waveform and the second energy waveform into a multiplexed signal.

19. The system of claim 18 , further comprising an impedance modification element configured to be positioned apart from at least one of the first pair of electrodes and the second pair of electrodes.

20. The system of claim 18 , wherein the first energy waveform is a pain-relieving energy waveform and the second energy waveform is a muscle-activating energy waveform.
