Abstract

Disclosed are methods and systems for non-invasive neuromodulation of the occipital nerves using ultrasound transducers to treat migraine and cluster headaches in their multiple variations as well other pain and tension conditions. Treatment may be unilateral or bilateral.

Claims

1. A method of non-invasively neuromodulating the target occipital nerves using ultrasound stimulation, the method comprising:

aiming an ultrasound transducer at the target,

applying pulsed power to said ultrasound transducer via a control circuit thereby modulating the activity of the target,

whereby therapeutic results are obtained.

2. The method of claim 1, wherein the plurality of control elements is selected from the group consisting of intensity, frequency, pulse duration, firing pattern, and phase/intensity relationships.

3. The method of claim 1 focusing the sound field of an ultrasound transducer at the target occipital nerves neuromodulating the activity of the target in a manner selected from the group of up regulation and down regulation.

4. The method of claim 1, wherein the acoustic ultrasound frequency is in the range of 0.3 MHz to 0.8 MHz.

5. The method of claim 1, where in the power applied is less than 60 mW/cm².

6. The method of claim 1, wherein the configuration of ultrasound power is selected from the group consisting of monophasic and biphasic.

7. The method of claim 1, wherein a stimulation frequency for of 300 Hz or lower is applied for inhibition of neural activity.

8. The method of claim 1, wherein the stimulation frequency for excitation is in the range of 500 Hz to 5 MHz for excitation of neural activity.

9. The method of claim 1, wherein the focus area of the pulsed ultrasound is 0.1 to 0.6 inches in diameter.

10. The method of claim 1, wherein the mechanism for focus of the ultrasound is selected from the group of fixed ultrasound array, flat ultrasound array with lens, non-flat ultrasound array with lens, flat ultrasound array with controlled phase and intensity relationships, and ultrasound non-flat array with controlled phase and intensity relationships.

11. The method of claim 1, wherein the neuromodulation of the occipital nerves is selected from the group consisting of unilateral and bilateral.

12. The method of claim 1, wherein the neuromodulation results in a durable effect selected from the group consisting of Long-Term Potentiation and Long-Term Depression.

13. The method of claim 1, wherein the disorder treated is selected from the group consisting of headaches in various forms, migraine headaches in various forms, cluster headaches in various forms, neuralgias, facial and other pain or tension syndromes.

14. The method of claim 1, wherein the ultrasound neuromodulation results in activation of the hypothalami, the thalami, the orbito-frontal cortex, the prefrontal cortex, periaqueductal gray, the inferior parietal lobe, and the cerebellum.

15. The method of claim 1, wherein the ultrasound neuromodulation results in deactivation of the primary motor area (M1) the primary visual area (V1), the primary auditory area (A1), and the somatosensory (S1), the amygdala, the paracentral lobule, the hippocampus, the secondary somatosensory area (S2), and the supplementary motor area (SMA).

16. The method of claim 1, wherein ultrasound therapy is combined with one or more therapies selected from the group consisting of medications, electrical stimulation, local anesthetic blocks, surgical transection, surgical resection, radiofrequency, alcohol/phenol infiltration, radiosurgery, cryotherapy, medication, avoidance of triggers, diet modification, physical therapy, chiropractic manipulation, and acupuncture.
