- •2.3.1. Has at least two of 2.3.1.1-2.3.1.4 (below):
- •2.3.1.1. Unilateral location
- •2.3.1.2. Pulsating quality
- •2.3.1.3. Moderate or severe pain intensity
- •2.3.1.4. Aggravation by or causing avoidance of routine physical activity (e.g. walking or climbing stairs) and at least one of 2.3.1.4.1. or 2.3.1.4.2. (below):
- •2.3.1.4.1. Nausea and/or vomiting

- •2.3.1.2. Treated and relieved by triptan(s) or ergot before the expected development of C1 above.
- •2.3.2. No medication overuse and not attributed to another causative disorder
- •3. Are refractory to conventional pharmacological CM treatment as defined by the failure to respond, or the intolerance, to at least 3 prophylaxis therapies (of which one is topiramate if not contraindicated).
- •4. Have failed botulinum toxin type A treatment, defined as less than a 30% reduction in headache days per month after two treatment cycles, at least 3 months apart, with the last treatment minimum 3 months ago
- •5. Are on optimal and stable CM prophylaxis therapy for at least 2 months.
- •6. Developed CM before the age of 60
- •7. Be an appropriate candidate for cervical SCS and for the surgical procedures required in this study based on the clinical judgment of the implanting physician
- •8. Be willing and able to comply with study-related requirements, procedures, and visits and to keep headache diaries
- •9. Be capable of subjective evaluation, able to read and understand English-written questionnaires, and are able to read, understand and sign the written inform consent in English
- •10.Have adequate cognitive ability to use a patient remote control and recharger as determined by the Investigator
排除标准
- •1. Have a medical condition or pain in other area(s), not intended to be treated with SCS, that could interfere with study procedures, accurate pain reporting, and/or confound evaluation of study endpoints, as determined by the Investigator
- •2. Have a contraindication to the cervical placement of SCS leads as determined by the investigator.
- •3. Have a PHQ-9 score of more than 19
- •4. Have previously diagnosed untreated severe psychiatric disorder(s)
- •5. Have a known history or suspicion of substance abuse or addiction (including alcohol and illicit drugs) as determined by the investigator
- •6. Have a current diagnosis of a progressive neurological disease such as multiple sclerosis, chronic inflammatory demyelinating polyneuropathy, severe arachnoiditis, severe peripheral neuropathy, brain or spinal cord tumor, central deafferentation syndrome, Complex Regional Pain Syndrome, acute herniated disc, severe cervical spinal stenosis or other as determined by the investigator
- •7. Have a current diagnosis of a coagulation disorder, bleeding diathesis that would put patient at any increased risk of bleeding during SCS procedure, progressive peripheral vascular disease or uncontrolled diabetes mellitus
- •8. Have an existing drug pump and/or another active implantable device (switched On or Off) such as a pacemaker or other SCS devices
- •9. Non-invasive neuromodulation is being used or planned
- •10. Previous exposure to any implantable neurostimulation device
- •11. Alternative therapy to treat migraine is being used or planned (e.g. acupuncture, acupressure, biofeedback, homeopathy)
- •12. Have a condition currently requiring or likely to require the use of MRI or diathermy
- •13. Have metastatic malignant disease or active local malignant disease
- •14. Have a life expectancy of less than 1 year
- •15. Have an active systemic or local infection
- •16. Be pregnant or breast-feeding (Female subjects of child-bearing potential must have a HCG negative blood serum test prior to implant and must be willing to use an adequate method of birth-control for the duration of the study)
- •17. Be concomitantly participating or planned to be participating in another clinical study
- •18. Have a pending or approved worker’s compensation claim, and an ongoing planned litigation related to work
