Study Summary
When a patient gets DBS surgery, the neurosurgeon makes a hole in the skull through which they can put the DBS lead down in deep parts of the brain that help control movement. For this study, research participants will also have an ECoG strip put through the same hole (no extra holes are being made for research purposes). The ECoG strip is a little less than half an inch wide, and a little more than 2.5 inches long. It is very, very thin; it is a thin plastic film with flat metal sensors that can record the electrical activity in the brain. The ECoG strips are FDA approved. The neurosurgeon will slide the ECoG strip under the skull but on top of the brain, over another area of the brain that helps control hand/arm movement (motor cortex), so that the study team can record the activity there. The study team will record brain activity from the DBS lead and the ECoG strip simultaneously to try to understand how the brain communicates and sends information. The study team will check that the ECoG strip is in the right place by delivering a very small electrical pulse to the wrist. If the ECoG strip is in the correct location, this electrical pulse will show up on the brain activity being recorded by the sensors in the ECoG strip. Fluoroscopy (i.e. X-ray images that can be taken quickly) will also be done at the end of the surgery to help confirm the location of the ECoG strip. During fluoroscopy, an X-ray beam is used to track a contrast agent ("X-ray dye") through the body, so that the body can be seen in detail. This involves some radiation exposure for the participant, so this is described in the consent form. Patients who want to sign up for the study will not be allowed to do so if they have had other radiation exposures within the past year that would go over a safe limit when added to the amount of radiation expected from the fluoroscopy for this study.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06692920
The ClinicalTrials.gov registry entry for NCT06692920 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 25 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Minnesota, which has 919 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Parkinson Disease appearing as the primary indexed condition, and to 1 intervention — of which DBS stimulation is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06692920 reports 1 study location spanning 1 distinct geographic area — top geographies include Minnesota. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
