About this trial
The primary purpose of this research is to evaluate a new kind of noninvasive brain stimulation intervention using the investigational ultrasound device, which might be useful for treating fibromyalgia. The device is for investigational use only and is not yet approved by the FDA for the intended use.
* Participants will be asked to visit the study center 7 times for in-person assessment and treatment sessions. In addition, participants will be asked to complete an online assessment 7 times. During in-person or online visits:
* Participants will undergo an MRI scan twice during the first and last in-person visit (1 hour each) The second MRI may be optional. * There will be 6 treatment sessions (45 minutes each) within a 2-week period * The online assessment occurs (15 minutes each)
* two consecutive days before the first treatment session * 15 days after the first treatment session * 22 days after the first treatment session * 29 days after the first treatment session * 44 days after the first treatment session * 60 days after the first treatment session
