What this trial studies

This study evaluates the effects of transcranial Direct Current Stimulation (tDCS) combined with Transcranial Ultrasound (TUS) on individuals with opioid-use disorder and chronic pain. Participants will receive either active stimulation or sham stimulation to determine the impact on drug use and psychosocial assessments. The study aims to establish whether active stimulation leads to better outcomes compared to a placebo effect. The research is designed to provide insights into innovative treatment options for addiction in the context of chronic pain.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 with a diagnosis of opioid-use disorder and chronic pain lasting more than six months.

Not a fit: Patients who are pregnant, have a history of neurological disorders, or are currently using certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could offer a novel non-pharmacological treatment for individuals struggling with opioid addiction and chronic pain.

How similar studies have performed: While the combination of tDCS and TUS is a novel approach, previous studies have shown promise in using brain stimulation techniques for addiction treatment.

Inclusion Criteria

Participants must meet all of the following:

* Provide informed consent
* Age 18-85 years
* Diagnosis of opioid use disorder (DSM-5) with ongoing non-prescription opioid use confirmed by self-report and urine toxicology
* Report current opioid craving
* Enrolled in a certified Opioid Treatment Program and receiving methadone maintenance treatment

* Reside locally with no plans to relocate during the study Exclusion Criteria

Participants will be excluded if they:

* Are pregnant
* Have frequent illicit stimulant use or acute stimulant intoxication
* Are using substances or medications that may interfere with study assessments (e.g., stimulant medications, buprenorphine-based therapies, naltrexone)
* Have significant neurological conditions (e.g., stroke, epilepsy, brain tumor), abnormal EEG findings, history of brain surgery, significant head injury, or unexplained syncope
* Have contraindications to noninvasive brain stimulation (e.g., metal in the head, implanted brain devices)
* Have moderate to severe depression or active suicidal ideation/behavior
* Have active malignancy
* Consume substances that could confound opioid toxicology results (e.g., poppy-seed products)
