简要总结
The purpose of this study is to assess the effectiveness of craniofacial nerve stimulation for the treatment of neuropathic pain.
详细描述
Subjects will be randomized at enrollment into either a delayed or immediate continuation group. The immediate continuation group will immediately continue with the stimulation after a 30-day trial period and will be monitored for a total of 12 months. The delayed activation group will have their device turned off after the 30-day trial period for the next 3-months. At the 3-month visit, both groups be evaluated and the delayed activation group will have their devices reactivated.
Subjects will have neuropathic pain of various etiologies, including trauma, surgery or post-herpetic infections. Stimulators will be placed at the site target of the painful area, including the epifascial plane under the skin but above the muscles in the vicinity of the targeted branches of; A. Branches of Trigeminal Nerves in the Ophthalmic, Maxillary, or Mandibular B. Sensory branches of Facial Nerves C. Branches of the Occipital Nerves (Greater and/or Lesser) D. Branches of the Cervical Plexus (Superficial and/or Deep)

入选标准
- •Subject is ≥ 18 years of age at time of informed consent
- •Subjects have been diagnosed with Cranial-facial pain with an average VAS > 5 (on a 0-10 scale) over the course of the last month based on baseline pain diary.
- •Subject diagnosis with neuropathic cranial-facial pain refractory to conventional medical management for at least 12 months prior to enrollment;
- •Based on the medical opinion of the Principal Investigator, subject has a stable pain medication regimen for 3 months prior to study entry.
- •Based on the medical opinion of the Principal Investigator, subject has a stable Tricyclic regimen for 3 months prior to study entry
- •No medication overuse and not attributed to another causative disorder
- •Based on the medical opinion of the Principal Investigator, there is no evidence of anatomic abnormalities that could jeopardize the placement of the device or pose a hazard to the subject;
- •Based on the opinion of the Principal Investigator, subject is willing and able to operate the patient programmer, recharging equipment, diary and has the ability to undergo study assessments and provide accurate responses;
- •Based on the opinion of the implanter, subject is a good surgical subject for the implant procedure;
- •Subject is willing to undergo surgical implant procedure, attend visits as scheduled, and comply with the study requirements;
- •Subject is male or non-pregnant female as determined with a negative pregnancy test at baseline visit, and if sexually active, must be using a medically acceptable method of contraception for the duration of their study participation;
- •Subject is deemed to be neuro-psycho-socially appropriate for implantation therapies based of the assessment of a Clinical Psychologist, using face-to-face encounters and the psychological testing described in the measures;
